introduction

With the development of society, the situation of electricity consumption in the dormitory of colleges and universities has undergone tremendous changes. Electronic equipment, communication networks, and cable television have all entered student dormitories. Induction cookers, electric water heaters, etc. involving electricity safety are also used. Enter at the same time. Today, large-scale public buildings have been established nationwide. Dormitories in colleges and universities have all been listed as major concerns. Each institution has successively established regulations for the use of water and electricity, management of the use of air-conditioning equipment, measures to strengthen conservation of electricity and electricity, and implementation of measurement supervision. Methods and so on. How to effectively manage energy in dormitory applications without sacrificing the need for electricity and the security of electricity use is a matter of total consideration.

1. Specification requirements

In the “Code for the Design of Dormitory Buildings” JGJ36-2005 Section 6.3 Electrical, the basic requirements for the design of the dorms were put forward: 6.3.1 The electricity load standards for each quarter of the dorms were stipulated. 6.3.2 Provisions have been made for the use of electricity in the public areas of dormitories and in the dormitory rooms for minors. 6.3.3 Security requirements are put forward for the design of the distribution system of the dormitory. Can refer to the implementation in the design. But often the construction unit has its own management needs, so in addition to the implementation of design specifications in the design, but also from the perspective of the user's management, comprehensive design.

On December 7, 2009, the Ministry of Education of the People's Republic of China and the Ministry of People's Republic of China jointly issued Order No. 28, “Regulations on the Administration of Fire Safety in Colleges and Universities,” which set out clear requirements for rectification measures for fire hazards in colleges and universities:

Article 32 In the case of fire hazards that cannot be eliminated in a timely manner, the entity with the hidden danger shall promptly report to the head of the fire safety manager of the school and related units or the leader of the fire safety work safety, put forward a rectification plan, determine the rectification measures, deadlines, and the department responsible for rectification, Personnel and implement rectification funds.

2. Design requirements

In the dormitory building, the distribution design of the dormitory should be comprehensively considered in terms of management requirements, safe use of electricity, and reasonable use of electricity.

1) Management requirements: Traditional time-limited power supply methods are no longer adapted to the needs of development, and the method of charging electricity bills from the average accommodation fee is not suitable for the current management model. It is imperative to implement electricity commodification using on-demand power purchases. Imperative management tools.

2) Safe use of electricity: Electricity safety is an important part of dormitory management and students' use. Students should avoid the situation of fire caused by overload when using electrical equipment. Therefore, overloaded automatic power-off control measures should be considered in the design.

3) Proper use of electricity: Although electricity consumption is adopted for students, it is not completely liberalized. In order to cultivate students to save electricity and good living habits, and regulate the student's daily routine, it is necessary to implement a timed control strategy for electricity circuits in student dormitories.

3. Dormitory Electricity Metering Management System Solution

Ankerui integrates many years of experience in the implementation of electric energy measurement management systems, and designs and provides electric energy measurement management system solutions for dormitory electricity consumption.

3.1 Detailed explanation of system function

1) Electricity metering and billing: When the user dormitories use electricity, the circuit corresponding to the meter is automatically metered (automatically decremented) and the metering accuracy is up to 1.0.

2) Remaining battery low limit alarm: When the remaining power of the subscriber unit has been reduced to the set low limit (usually set to 10 degrees), the system will automatically prompt the user to purchase electricity as soon as possible without powering off the unit.

3) Remaining power is not charged off: The user should first purchase electricity from the school's designated power purchasing department. The power-selling computer will automatically send data to the power unit corresponding to the multi-user power meter to automatically complete the user's power supply. When the user's remaining power is At zero hours, the system will automatically cut off the unit's power supply, and the system will automatically restore the unit's power supply only when the user repurchases power.

4) Regular power control: The school can control the time of students' electricity consumption according to their own management requirements, and can provide two sets of control time tables for holidays and work days.

5) Load limitation: The school can set the maximum load of the student user unit according to its own management requirements. When the actual load of a unit exceeds the set power load, the system will automatically cut off the power supply of the unit, automatically power on after 3 minutes, if the user's load still exceeds the limit, the power meter will again power off, so 3 times After that, it will be permanently powered off and can only be powered back to the management center.

6) Checking electricity consumption in dormitory: Through the system software, the user can inquire about the electricity usage situation of the user dormitory at any time: current active power, accumulated electricity consumption, remaining electricity and other information.

7) Remote meter reading: This system does not require staff to go to the scene to collect power consumption, but directly collects power consumption data on the management computer through the data collector.

8) System Operation Log, Account Operation Log, and Trace Audit: The system records operator actions in the database and traces all operations.

4. The significance of building electricity measurement management system for dormitory

The introduction of electricity measurement management systems for residential quarters in schools has the following advantages:

4.1 From the perspective of charging management

In the past, the vast majority of schools counted student electricity charges as accommodation fees. With the increasing use of household appliances in student apartments, the disadvantages of such fee management methods became more apparent. Students felt that such fee management was unreasonable.

After introducing the electricity measurement management system into the dormitories, the prepaid electricity management method has been truly implemented. How much electricity is used by the students is more than necessary, and when the students change the dormitory, the data can be converted. When the students graduate, they can also retire. The fees are scientific and reasonable, and at the same time, they develop the habit of students saving electricity.

4.2 From the perspective of management workload

Now that the logistical management of dormitories has tended to be socialized, many schools have divided this work into logistical service companies. For a company, the most desired thing is to use less money in return for larger benefits and follow old-style management methods. Logistic management needs a lot of manpower support; and the introduction of electricity measurement management systems for dormitory will greatly reduce the workload of logistics management, mainly reflected in:

1 timing control

In order to develop students' energy-saving electricity and good living habits, they all provide time for electricity supply. Administrators need to turn on and off the power supply of the dormitory at the prescribed time every day. They always get up earlier than the students and sleep late than the students; After using the electricity metering management system, the school can use the time control table for students' electricity consumption according to their own management needs.

2 centralized meter reading

Many schools have stipulated that the electricity consumption of each dormitory should be collected during certain periods of time. This is not only a heavy workload but also easily error-prone; the introduction of dormitory electricity consumption measurement management system does not require staff to collect electricity from the site. Copying, but directly through the data collector to collect electricity data to the management computer. Whenever it is necessary to view the electricity consumption of the student dormitories, they can be summarized at a glance, quickly and accurately, and the workload of logistics managers is greatly reduced.

3) Real-time monitoring

In the past, if you want to know the electricity situation of the student dormitories, you need to go to the dorm to see it. After introducing the dormitory electricity measurement management system, the administrator can directly see the dormitory electricity status directly in the duty room. When any fault occurs, there will also be a display on the real-time monitoring interface.

4.3 From the perspective of financial management

After introducing the dormitory electricity consumption measurement management system, the operator can log in to the system only with his own user name and the correct password. The system will provide services for the operator according to his authority. At the same time, the database will record all operations of the operator and can be recorded at any time. Query through the system.

4.4 From the perspective of electricity safety

The dormitory is a place for students to study and live. Safety is of primary importance. When students use electricity, it is inevitable that there are irregularities. It is easy to produce electricity accidents because of publicity or students' self-consciousness. The electricity accidents that occur in colleges and universities will cause trouble to schools and cause harm to students. Such accidents have also been reported by the media. After the introduction of electricity measurement management systems for residential quarters, major electricity accidents such as fires caused by electricity will never occur, because the dormitory electricity consumption measurement management system can carry out load limitation and use technical means to cut off electricity, completely eliminating major Security risks.
