　　Pre paid electrical control system for school dormitories

　　1、 Platform Introduction

　　The construction of smart and safe campuses is becoming increasingly popular. As an important part of smart campus construction, the prepayment of electricity and electricity safety management measures for student dormitories are essential. The prepaid electrical control system for student dormitories can solve the drawbacks of traditional manual meter reading, which is time-consuming, labor-intensive, inconvenient for statistical management and recharging. It also provides a solution for the electrical safety of student dormitories, eliminating fire hazards caused by the use of malicious loads.

　　The prepaid electrical control system for school dormitories integrates functions such as energy metering, billing management, and power consumption process management. It has remote real-time meter reading and metering, control of student schedules, identification and warning of malicious loads, self-service payment for campus one card, query, and printing of energy consumption reports. It creates a cost-effective and safe campus, facilitates information management by the school, and supports data integration with the smart campus system.

　　2、 Platform Features

　　◆ B/S architecture

　　The system design adopts B/S architecture, which does not require the installation of a client. Users can complete all operations such as configuration, setting, querying, and control through a browser. And it can support more users to be online at the same time.

　　◆ Query function

　　Students can use their mobile phones to recharge and check their electricity usage on the One Card platform. The platform has a user remaining battery reminder function.

　　◆ Three loop independent control

　　It can be divided into three independent power distribution channels: air conditioning, sockets, and lighting. The power supply protection, power supply control, and power supply time of the two power sources are independent of each other.

　　◆ Time control

　　According to the actual requirements of the school, effective date settings, holiday settings, on/off settings, and comments can be made, and the already set ones can be filtered and viewed.

　　◆ Remote real-time meter reading and measurement function

　　The system can remotely read real-time electricity data, which is uploaded to the system data server through the data gateway.

　　Real time monitoring, identification, warning and control of malignant loads

　　The system has the function of identifying malignant loads, automatically identifying various types of malignant loads prohibited by the college regulations (such as fast heating, hair dryer, electric blanket, hand warmer, etc.), and automatically cutting off power to protect the electrical safety of the dormitory.

　　◆ Automatic power restoration function

　　Power supply can be automatically restored after overload power outage or automatic power outage using malicious loads, and the automatic power supply time can be set. Managers can set the number of automatic power supply times. If the set number of times is exceeded, the system cannot automatically supply power anymore. After finding out the cause of the power outage with the administrator, the power supply management personnel will manually restore the power supply.

　　◆ Household billing management

　　It can provide free basic power settings, pre order power, no fee shutdown, power usage inquiry, refund management, support for changing operators midway, printing reports, etc.

　　◆ White list management

　　This function is used to maintain the whitelist information of electrical appliances. The system supports learning function and comes with a database of no less than 30 commonly used electrical appliance usage characteristics in schools. Electrical appliances that are not in the feature database can be entered into the database through on-site learning to distinguish between malicious loads and whitelist loads.

　　◆ Low current at night

　　The dormitory can be set to use low current at night, which can only be used for charging mobile phones or night lights.

　　◆ Main functions

　　Electrical Characteristics

　　◆ Control function

　　1. Prepaid management control

　　Support prepaid function. Basic amount can be set for free use; Four levels of alarms can be triggered for the remaining amount: insufficient balance alarm (level 1), pre trip alarm (level 2), overdue alarm (level 3), and reaching the credit limit alarm (level 4). Each level of alarm will cause the backlight of the electricity meter to remain on. The pre trip alarm tripping mode can be set to not trip, automatically close after tripping, or not close after tripping. After tripping, the electricity meter can be automatically closed by pressing the button. When the credit limit is reached, the electricity meter will trip, and only after payment can it continue to be closed for use.

　　2. Time management control

　　Support time management control. L1, L2, and L3 can be set to work day and holiday modes respectively. There are 8 time periods that can be set each day, and each time period can be set to either on state or night mode. During the on state period, the electricity meter remains on, and during the night state period, if the branch power exceeds the upper limit of the night allowable power, it will trip.

　　3. Load management control

　　Support rich load management control, with specific working functions as follows:

　　Current upper limit limitation: Limit the branch current. When the branch current exceeds the set value, the branch trips.

　　Load total power limit: Limit the power consumption of the branch. When the branch power exceeds the set value, the branch trips.

　　Nighttime power limit: It needs to be used in conjunction with time management control. In night mode, if the branch current exceeds the set value, the branch will trip

　　4. Malignant load identification: Restrict branch access to undefined malignant loads, and trip the branch when it is connected to an unauthorized malignant load.

　　Load whitelist recognition: Allow defined loads with malignant load characteristics to be used normally (such as water dispensers, etc.).

　　Air conditioning mode: In air conditioning mode, the electricity meter continuously detects the weak standby current of the air conditioner. Once there is an action of unplugging the air conditioner socket, the electricity meter trips and can only be closed and powered on by management personnel.

　　Allow automatic closing of tripping actions other than air conditioning mode. The allowed number of times and the waiting time for tripping can be set.

　　◆ Installation appearance

　　The IC card prepaid energy meter adopts a management mode of purchasing electricity first and then using it, which to some extent solves the problem of difficulty in collecting electricity fees for the power department. However, there are significant problems with IC card prepaid energy meters. Firstly, due to the lack of supervision by the power sector over IC card energy meter users, it is difficult to detect and investigate when the IC card is compromised, resulting in a significant loss of electricity bills for the country; Secondly, IC cards are prone to contamination and damage.

　　The main purpose of this design is to solve the problems of IC card prepaid energy meters, while inheriting the management mode of purchasing electricity first and then using it. The management microcomputer of the power department manages the electric energy meter through RS485 network to prevent users from stealing electricity; Selecting RF cards as user cards to solve the problem of IC cards being easily contaminated and damaged.
