ICFeasibility Analysis Report of Card Intelligent Water Control System
KBSThe series of smart card water controllers is a high-tech intelligent water-saving management system developed by Guangzhou Zhengfeng Electronic Technology Co., Ltd. according to my country’s current water conditions and actual characteristics. This system adopts the method of using the user to insert the card to produce water, remove the card and cut off the water. Through the management card, rate setting and data collection can be easily carried out without complicated networking. The operation is simple and easy to use. Wide range of applications: such as schools, industrial and mining, public bathrooms, boiling water rooms, rental houses, laundry rooms, etc. KBS series intelligent water control system is a new measure to solve the waste of water resources. At present, water saving has become an urgent problem to be solved in the world. To save resources and prevent waste, Zhengfeng Electronics will provide you with the most perfect solution!
Will the water control management system produce real economic and social benefits? When to recover the investment cost is the most concerned issue for investors. Let us first look at the following set of data: This is a college (the school has a total of about 12,000 teachers and students) after the smart card water control system is installed, and other factors are basically the same, the logistics management department of the school has been carefully The results of comprehensive statistics and field tests.
From the above table, it is not difficult to see that after using the smart card water control system, although the total income of the school is the same, the expenditure has been reduced by two-fifths, and the monthly income has increased by about 25,000 yuan. At the same time, it saves nearly two-fifths of water and coal. , The economic benefits are quite obvious.
Let us do a simple analysis:
1, Before installing the water control system
The student bathroom of the school is open 6 times a week, each bathing time is 4 hours, an average of about 1,400 people take a bath every day, the total number of shower heads in the bathroom is 200, which is open 25 days a month, and the flow rate of a nozzle is about 0.7 tons per hour measured on site. .
Based on this calculation, every time the bathroom is opened, the water consumption will reach: 0.7×4×200=560 tons; the average time for students to take a bath is: 60 minutes ÷ (1400 ÷ 4 ÷ 200) = 34.2 minutes (including part of the Waste water time by closing the valve). If coal is used for heating, the price per ton of hot water is 3 yuan (oil heating is about 22 yuan, natural gas is about 18 yuan). Calculated according to the normal bathing time, boys need an average of 15 minutes, girls need 25 minutes, and the actual average time is 34.2 minutes, of which 14.2 minutes are wasted mercilessly. Therefore, every time the school opens the bathroom, 0.7×14.2÷60×1400=231.9 tons of water are wasted mercilessly; the extra cost is 3 yuan/ton×231.9 tons=695.7 yuan (oil is 5101.8 yuan, natural gas is 5101.8 yuan). Is 4174.2 yuan). Calculated on the basis of 6 months of bathroom usage a year, the school’s water waste and expenditure are shocking!
Based on this calculation, every time the bathroom is opened, the water consumption will reach: 0.7×4×200=560 tons; the average time for students to take a bath is: 60 minutes ÷ (1400 ÷ 4 ÷ 200) = 34.2 minutes (including part of the Waste water time by closing the valve). If coal is used for heating, the price per ton of hot water is 3 yuan (oil heating is about 22 yuan, natural gas is about 18 yuan). Calculated according to the normal bathing time, boys need an average of 15 minutes, girls need 25 minutes, and the actual average time is 34.2 minutes, of which 14.2 minutes are wasted mercilessly. Therefore, every time the school opens the bathroom, 0.7×14.2÷60×1400=231.9 tons of water are wasted mercilessly; the extra cost is 3 yuan/ton×231.9 tons=695.7 yuan (oil is 5101.8 yuan, natural gas is 5101.8 yuan). Is 4174.2 yuan). Calculated on the basis of 6 months of bathroom usage a year, the school’s water waste and expenditure are shocking!
2、Operation status after installation of equipment
After the installation of this system, due to the greatly increased utilization rate of the shower head, the students’ awareness of saving water has increased significantly, so that the number of bathing persons per day can be increased to 2,000, the bathing time is also shortened to 20 minutes, and the water consumption per hour for each nozzle is reduced to 0.7 tons. If the charge is 0.06 yuan per minute (0.22 yuan for oil and 0.18 yuan for natural gas), then the net income per day is 0.06 yuan × 20 × 2000-3 yuan × 0.7 × (20 × 2000 ÷ 60) = 1,000 yuan. At the end of a year, calculated on a 6-month period, the net income can be 1,000 yuan × (182 ÷ 7 × 6) = 156,000 yuan. Now the average daily water consumption is more than 340 tons, saving two-fifths. So, will the use of intelligent water control systems increase the burden on students? Will not. Taking boys as an example, the general bath time is 15 minutes, and the cost is about 1 yuan. Not only does it not increase, but it will decrease. Without installing this system, will raising the fee standard reduce losses? the answer is negative. Because of the increase in the fee standard, some students will undoubtedly be pushed to the public baths of the society, and the number of students who go to the school baths to bathe will become less and less, making the low income even more pitiful. In fact, this is also the loss of the school baths. The real “curse”; even if fees increase, school baths will also lose money if they lack effective management methods and do not save water. According to statistics, a school bathroom with about 300 sprinklers will lose more than 60,000 yuan per year if it is used for six months a year. The use of intelligent water control systems will not only make up for the loss, but also make up for the loss every year. With an increase of more than 100,000 yuan in income, the benefits of using this system are self-evident. At the same time, the smart card water control system has low investment and quick results. A set of 200-point system requires only 100,000 yuan in investment, and the school can basically recover it in one year (mainly from saving).
Using a smart card to control the water system, while saving capital and increasing income, it can also bring many benefits to users:
1. The charges are more fair and reasonable. Charge for more water, and charge less for less water, which is more in line with the consumer psychology of students, and it also avoids the bad habit of some students deliberately wasting water and delaying time.
2. Reduce the labor intensity of the staff. The system is an unmanned system. It is sufficient to have a manager at the entrance of the bathroom. The staff can be appropriately streamlined to save labor costs. The manager no longer has to worry about students not swiping their cards or giving tickets. It is truly modern and scientific management. , Which greatly improves the management level.
3. The water controller can be used completely offline, avoiding failures caused by network wiring.
my country is a country with severe water scarcity. According to statistics, my country’s per capita water share is less than one-tenth of the world average. With such scarcity of water resources, my country’s water waste is quite serious. Water conservation is urgent. Although my country is also vigorously advocating water-saving projects, publicity alone is not enough. There must be a set of effective management methods and means. The use of intelligent water control systems is the ideal solution to the waste of water resources and difficulties in water management in colleges and universities. One of the options. After using the intelligent water control system, the most direct experience of major universities is that the water consumption has been significantly reduced, and the average water saving is more than half. A college of about 10,000 people uses an average of more than 100,000 tons of water per year. After adopting the smart card water control system, 50,000 tons of water can be saved each year, which brings amazing social benefits. Using this system can bring twice the result with half the effort, which can be described as “one time investment, lifelong benefit”.
