<br> Keywords: ic card-saving water control system-controlled water-saving controller <br> Summary: IC card water control system to improve management level, IC card can save water control system for schools economizing, save costs, IC card water .control system enables a wide range of social benefits. <br> <br> More than ten years, from the dining of the first round of the revolution to meal sale management system popularity from decentralised to access the campus network, both from a variety of .functions to a campus card-card technology matures, logistics management has always been at the forefront of reform on campus. But in recent years, various electric products on campus and high-tech products are becoming diversified, more quantitative era, abandon the old power .management mode, the power of commodity into logistics management reform a new hotspot. As the campus power management mode, metering modes and metering products in demand appeared. <br> <br> First, in the colleges of water, electricity management problems in the .current context: <br> <br> 1. in the area of management, in the absence of these products as well as the consumer's do not consciously, to student apartment fire safety aspects; <br> 2, free water and electricity to the .students create a wasteful habits, regular human walking hostel lamp off phenomena; <br> 3. use the vintage meter needs for meter reading, heavy workload, the charge is also a problem, often arise between members of the selection Committee <br> Or .simply did not pay for electricity phenomenon; <br> 4. social development students on their own learning and the increasingly high demands on the quality of life, televisions, computers and other electrical appliances in the dormitory has not uncommon that a new round of hostel .revolution trend will let go of power management direction. You can let go of power is also increased the burden of the school; <br> <br> Second, the IC card water saving / energy-saving equipment advantages: <br> <br .> 1, IC card control system to improve water management; implementation of management science and modern. Schools to use smart card after water-saving controller, like bath, laundry, open water, etc. all with their own water-saving card complete, .on-demand consumption, automated clearing, so that the rationalization, service charges, scientific management, eliminate waste. <br> <br> 2, IC card water control system for schools economizing and save costs. Using IC card after saving water control system .not only convenience while reducing school expenses: IC card automatically clearing functions reduce logistics managers, thus saving the manpower and artificial unit wage costs; the former bath, laundry is often tap open to let the water arbitrary outflow, and IC card after water-saving .controller does not exist without running water, because every drop of water waste is a waste of accounting in the water, so as to eliminate the waste of water, and reduces administrative costs with a party and water expenses. <br> <br> 3 ., IC card water control system enables a wide range of social benefits. Use water-saving controller IC card, so that the water automatically clearing, achieve more accurate, more efficient; reducing water waste, conserve water, electricity, fuel and other resources, .also made a contribution to society. The promotion and application of the system mainly to improve the efficiency of water use, strengthening economic accounting, so that every drop of water can play its maximum effect. Its primary benefit is the primary source for saving water, .saving this part of the water heating energy consumption (ranqi, coal-fired or electricity, etc.), the fees of the three aspects of access to benefit from savings, followed by Save section property management aspects of sewage treatment costs is also an important .aspect. <br> <br> <br> 4. energy-saving control system function characteristics <br> <br> 1) using special waterproof design, adapted to the baths and other environments. <br> 2) automatic water control and .charging, you can achieve unattended, use the e-wallet transactions, avoid managing vulnerabilities and more scientific and efficient. <br> 3) according to the actual water consumption or consumption billing deduction, water or power start billing, water or when billing is .stopped, the deduction of payment in real time, enabling individual consumption, consumers and contractors are fair and reasonable, taking into account their interests. <br> 4) due to billing deduction is visible, the consumer will consciously reducing water use by increasing water .supply / power supply units use the turnover rate, and thus serve to conserve resources. <br> 5) using real-time billing deduction, multi-use, no not more. Users do not need to use water power is consciously switching valve or .power switch, eliminate the waste of water / electrical phenomenon, saving valuable resources. Relative also reduces on water and power supply equipment capacity requirements. <br> 6) to buy the card after consumption, an effective solution to early-stage investment for equipment ., training of conservation consciousness, Lee Lee Lee enterprises, has promoted the construction of spiritual civilization. IC card management facilitate accurate, improves management efficiency and quality. <br> <br> 3. use the intelligent control system analysis <br> <br .> Water control and management system will produce a real economic and social benefits of? when payback is the school administrators are most concerned about. Let's look at the following set of data: <br> <br> Compare the installation after Setup <br> .Average number of 1800 persons / bathing day 2300 person / day <br> Students average pay $ 2 to $ 1.2 yuzi <br> Water per capita water the 110 l 383 l <br> Monthly consumption 18200 tons 6578 tons <br> Monthly price .(2.5 Yuan / ton) 45500 16445 <br> Per capita consumption of coal from coal 3.5 kg 1.06 kg <br> Monthly consumption of coal 163.8 tons 63.39 tons <br> Average monthly coal costs (300 yuan / ton) 49140 19016 <br .> Monthly gross income of $ 93600 71760 <br>-Total expenditure of $ 94640 35461 <br> <br> This is one University in Jiangsu Province (a total of 1 million students and teachers of the school for 5 thousand people) during the .installation of intelligent control system, other factors are basically the same, the school Logistics Management Department carefully comprehensive statistics and actual test results. <br> <br> From the above table is not difficult to see, using the intelligent control system, while nearly .one-third of school revenues decrease, expenses were reduced to threeParts per second, monthly revenue around $ 35000 while saving water, saving coal are approximately two-thirds of the economic benefits are obvious. <br> Let's do a simple analysis: <br .> <br> Economic benefits <br> <br> 1, the control of the system is not installed before school bathroom weekly open 6 times, each time the bath time is 4 hours, an average of about 1800 persons bath, bathroom shower head .totaled $ 250, field measured a nozzle flow per hour about 0.7 tons. <br> <br> 2, this calculation, the bathroom every open once water consumption reached: 0.7 × 4 × 250 = 700 tons; students each time the bath was .: 60 minutes ÷ (1800 ÷ 4 ÷ 250) = 33.3 minutes (including partial bath after closing valve of waste water in time). Such as the use of coal heating, the price per tonne of hot water for $ 7 (oil heating to .about $ 22, natural gas is about $ 18). Normal bath time calculation, the average needs of boys and girls need 15 minutes to 25 minutes, while the actual average available 33.3 minutes with 13.3 minutes be mercilessly wasted. Therefore, schools open a .bathroom that has 0.7 × 13.3 ÷ 60 × 1800 = 279.3 tons of water to be mercilessly wasted; many expenses 7 Yuan / ton × 279.3 tons = 1955.1 Yuan ($ for oil, natural gas-6930 5670 element). According to the year bathroom .use 6 months time calculation, the waste of water resources in the schools, the cost is so shocking! <br> <br> 3. install devices operating conditions: after the installation of this system, because the bath head usage dramatically improve student awareness .of the importance of saving every day noticeably enhanced allows to increase the number of bathing to 2300, bath time is reduced to 20 minutes, each nozzle reduces water consumption per hour is 0.5 tons. If you press 0.07 Yuan / minute (oil, natural gas .required $ 0.22 0.18 element), then a day of net income to $ 0.07 × 20 × 2300 - $ × 0.5 × 7 (20 × 2300 ÷ 60) = $ 537. One year down to net income of $ × 537 (182 ÷ .7 × 6) = $ 83772. Now the average daily water over 300 tons, saving nearly in half. Then, use an intelligent control system will increase the burden on students? does. To the boys, for example, General bath for 15 minutes ., about consumer 1 Yuan or so, not only does not increase, but also will be less. Do not install this system will increase the fees, losses? the answer is no. Because of the increased rates will no doubt be some students to public .baths and bath bath school students will become less and less, this is not high income becomes more poor, in fact, this is also true of the loss of school baths "curse"; even if a fee increase, but if there is a lack .of effective management tools, not to save water, school baths also be loss. According to statistics, a quantity in the 300 or so heads of school bathroom, annual losses to 15 million Yuan, and intelligent control system, not only compensate for the losses ., the annual increase revenue shijiwanyuan, the benefits of using the system is self-evident. At the same time, the intelligent control system for small, quick return on investment. A set of 200 or so system, investment requires only one year, the .school shijiwanyuan is fundamental to be able to recover (mainly from savings). <br> <br> 4, using the intelligent control system, in the Festival's income at the same time, you can also bring many benefits to schools: <br> .<br> First, save the students' bath waiting time. In order to grab on, the previous 4 point open bathroom, 3 point half even earlier students wait at the gate too late to students in the bathroom, and a waste of valuable time .for students. Now not only not at the door, but also do not have in it, and so on, to wash, to speed up the bath cycle, facilitates students, extension of the bathroom. <br> <br> 2. optimized .bath environment. Overcrowding, wash before bathroom not good bath and wear well, a lot of trouble, and now due to turnover, the capacity of the order of the bath, bathroom, environment, washing of comfortable rest assured. <br> <br .> 3. avoid embarrassment. See someone being bath nearby, so that and not let the awkward, acquaintances or teacher to the worse. Find the nozzle of their birthday looking around more bad, now have a number one, you can keep the change need .not let, completely avoiding the embarrassing. <br> <br> 4. fees and more equitable. More water fees, less water, less fees and, more in line with the consumer psychology students, while also avoiding certain students who deliberately wasted water ., delay time of bad habits. <br> <br> 5. reduce the labor intensity of the work. The system is a duty system, bathroom situated a managers sufficiently, staff can be reduced, saving labour costs, administrators no longer have to .worry about student not credit card, tickets, truly modern, scientific management, greatly improves the management level. <br> <br> 6. daily accurate bath number, income statistics report, no accounting loss. <br> <br> Social benefits .<br> <br> Our country is a serious shortage of water resources of the country, according to the material statistics show that China's per capita water occupation rate than the world average of 10%, while in the water so scarce cases, China's water .resources, waste and very serious, to conserve water has no delay. Although China has vigorously promote water-saving works, but only the propaganda is not enough, you must have a set of effective management methods and means, and the use of intelligent control .system is the University's waste of water resources, water management to one of the most ideal solution. Using an intelligent control system, all major colleges and universities most direct impact is obvious reduce water consumption, more than half the average saving water in. A million .or so colleges and universities, the average water use in thousands of tons, and intelligent control system, the annual saving 50 000 tons, of social benefits is amazing. Using this system, you can have a multiplier effect, can be described as "a .time investment, life-long benefit. "<br> <br> 4. intelligent control management system gains analysis <br> <br> More than ten years, from diningIn the first round of the revolution to meal sale management system popularity from decentralised .to access the campus network, both from a variety of functions to a campus card-card technology matures, logistics management has always been at the forefront of reform on campus. But in recent years, various electric products on campus and high-tech products are .becoming diversified, more quantitative era, abandon the old power management mode, the power of commodity into logistics management reform a new hotspot. As the campus power management mode, metering modes and metering products in demand appeared. <br> <br> I. .campus electricity management trends <br> <br> Hostel electricity management trends in the cost of the evaluation of schools <br> The first stage of the old fashioned knife gate out each bedroom below $ 20 <br> Low-cost, fuse fuse limit .load, no management function, not adapted to modern halls of power management needs of circuit breaker switch out each bedroom below 30 yuan, with leakage protection, each bedroom 50 Yuan <br> In the load control mode switch on a new, equally no management .function, but in the dormitory has set the power outlet, on the resulting electricity metering and billing requirements powerless <br> The second phase of the vintage meter transition products each bedroom below $ 100 <br> In knife gate or opening switch after the introduction ., is a school management to adapt to the new situation of a transition means, because of the cumbersome, a vulnerability that does not meet the regulatory requirements <br> IC card electricity transition products each bedroom 300 yuan <br> In the same venue in .knife gate, each bedroom for pre-paid electricity system, measurement accuracy, security, centralized management of statistics, not widely promoted and national electricity Office and several provinces electricity sector at the beginning of 2001 has been issued a circular, are not permitted to continue .to promote the IC card meter, installed must gradually replace <br> The third phase of the intelligent control system of intelligent products each bedroom below 350 Yuan <br> With intelligent control products. By top software, networking, control management Terminal, you can .implement with a card management with automatic operation control, comprehensive and descriptive statistics summary function, functional, cost, and usability aspects fully meet College user requirements. <br> <br> Second, intelligent control products before use, compare, after use <br .> <br> (A), the management of the comparison: <br> <br> ■ Intelligent control products before use: <br> 1. in the area of management, in the absence of these products as well as the consumer's do .not consciously, to student apartment fire safety aspects; <br> 2, free water and electricity to the students create a wasteful habits, regular human walking hostel lamp off phenomena; <br> 3. use the vintage meter needs for meter reading, heavy .workload, the charge is also a problem, often arise between members of the selection Committee or simply does not hand over the tariff of the phenomenon; <br> 4. social development students on their own learning and the increasingly high demands on the quality of .life, televisions, computers and other electrical appliances in the dormitory has not uncommon that a new round of hostel revolution trend will let go of power management direction. You can let go of power is also increased the burden of the school; <br> < .br> ■ Intelligent control products: <br> <br> 1, high security, not only for students of electricity metering, also play a role are these and eliminate the fire and so disastrous events; <br> 2. let go of power .to meet the students' learning, higher demands of life; <br> 3. enhance the consumer's power-saving consciousness, significantly reduces the power resources of invalid expenditures; <br> 4. prepayment type design eliminates meter reading, billing questions, or .difficult to reduce the workload of the managers; <br> 5, to reduce the school on the consumer release of electricity generated by the burden. <br> <br> (Ii) costs and economic benefits: <br> For a 1000 hostels .campus, for example, we can calculate the intelligent control system to the user. <br> Intelligent control products before use: <br> School district each Hostel in addition to the normal television sets, lighting and other electrical power, plus the amount of .power and other students of waste, every average electricity consumption of hostel 25 degrees; <br> If the average of each dorm two computers, each computer average 6 hours / day, monthly electricity consumption is 90 degrees. Per unit of $ 0.5 standard calculations ., the school district as a whole should pay for electricity will reach (90 + 25) * 0.5 * 1000 * 8 = $ 460000.00 <br> Apart from the daily lighting $ electricity due to liberalization of electricity, schools must also bear the additional $ .36 million. <br> <br> ■ Intelligent control products: <br> <br> When using electronic control system, because the school district's student electricity charge, students will consciously save electricity, then schools per month you can give each dorm 20 .degrees free electricity charges, saving over the accumulated. School students free electricity charging 0.7 Yuan / degree. Then <br> <br> A. paragraph 30 million investment in equipment. <br> B. students should pay the electricity bill for the full .year of about 90 * 0.7 * 1000 * 8 = 504000.00; <br> C. school district spending on tariffs of the year (90 + 20) * 0.5 * 1000 * 8 = 440000.00; <br> D. the school's electricity 440000 - .504000 =- 64000.00 element; <br> Calculation in accordance with the above, the school district uses intelligent control products of first-year school expenses for 440000 + 300000-504000 = $ 236000.00 than the same period of the previous year expenditure savings 460000 - .236000 = 224000.00 element; <br> <br> From the second year, due to the use of intelligent control products for electricity management, school not only saves electricity, at the end of the school district will also recover 64000 profits. <br> .<br> Use comparative earnings before and after <br> <br> Compare project before using smart electronic control systemAfter using smart electronic control system <br> Management model releases electricity deregulation of electricity, school monthly free supply each dormitory, exceeding 20 ° electric .charges <br> Average power consumption 11.5 million degrees 11 million degrees <br> Year tariff paid situation 46 million 44 million <br> Tariff seizures no 100% <br> Tariffs of the principal schools 100% users <br> School profitability without 64000 .<br> <br> From the above series of calculation is not difficult to see that the use of intelligent control products not only can meet the students' learning and life quality requirements, ease the school open electricity, but also as a self-financing .logistics group brought economic benefits. <br> But after installing electric control system, power waste situation has been significantly improved, not only saving of nearly one million unnecessary waste, tariff collection rate can reach 100%. <br> Thus, in the campus .socialization management reform, use control management system is a campus management trend. <br> <br> <br> <br> <br>.
