Set up a prepaid energy meter: Each dormitory should be equipped with a prepaid meter. The meter can be topped up via a mobile app or card, allowing users to add electricity bills at any time before they run out.
Install an intelligent remote control system: Set up a power management system to control and monitor power usage. It can automatically cut off the power supply when the electricity consumption exceeds the preset value, avoiding the overdraft of the electricity bill.
Use mobile payment platforms: Use mobile payment platforms such as Alipay and WeChat to provide convenient payment methods for electricity bills in student dormitories.
Reminder service: Regardless of whether the student is ** or not, when the remaining power is lower than a certain threshold, an automatic reminder should be sent to help the student replenish the electricity bill in time.
Energy Consumption Education: Through education, students will be raised to pay attention to energy conservation and environmental awareness.
Power query and consumption details: The system should provide real-time power remaining query, historical power consumption statistics and other functions, so that students can clearly know their power usage.
Hold energy-saving competitions: To stimulate students' awareness of energy conservation, you can hold power-saving competitions between dormitories to see which dormitories use more electricity.
Set a fair electricity price: Ensure the fairness of the electricity price and adjust the electricity tariff in a timely manner according to the electricity market**.
Create an online community: Create an online community for all students, where students can discuss electricity use issues, share energy saving experiences, and raise awareness together.
Complaint and feedback function: Set up an easy-to-use complaint and feedback function so that students can give feedback in time when they encounter problems, so as to facilitate the quick resolution of problems.
Management of prepaid electricity consumption in school dormitories.
DDSY1352 Single-phase prepaid energy meter (dormitory electricity management terminal) is mainly used to meter single-phase AC electricity, which is suitable for electricity management in student dormitories (apartments). The terminal can be one live wire incoming, multiple live wire parallel output, there are three ways, four ways and no way to choose, can be metered lighting, sockets, air conditioning circuits, toilets, water heaters, etc.;It can be prepaid control, and can carry out load control and time control for each outgoing line respectively, and support nearly 30 trip event recording and storage functions, so as to realize the power commercialization, power safety and on-demand control of power management in school dormitories.
Gauge function. Key features:
Control functions. Prepaid control.
The dormitory power management terminal supports the prepayment function
A base amount can be set for students to use for free
Four levels of alarm can be carried out on the remaining amount: insufficient balance alarm (level 1), pre-trip alarm (level 2), arrears alarm (** alarm when the upper limit of credit is reached (level 4);
Each level of alarm will cause the meter backlight to be always on, the tripping mode of the pre-trip alarm can be set to not tripping, automatic closing after tripping and not closing after tripping, after tripping, students can close by themselves by pressing the button, and the meter trips after reaching the upper limit of credit, at this time, only after paying the fee can continue to be transmitted.
3.2.2. Time control.
The dormitory power management terminal supports time management control
Each circuit can be set to weekday and holiday mode, respectively
You can set up to 8 time slots per day
Each time period can be set to either closed or night mode
The meter remains closed during the closing period, and during the night time period, you can choose to trip directly or trip after the power is greater than the allowable power at night.
Load management control.
The dormitory power management terminal supports rich load management control, and the specific working functions are as follows:
Current Upper Limit Limit: Limit the maximum current of each branch, when the branch current exceeds the set value (<16A), the branch trips.
Total load power limit: Limit the maximum power consumption of each branch, and each branch can set different total power thresholds. When the power of the branch exceeds the set value, the branch trips.
Night Power Limit: Requires use in conjunction with time management control, in night mode, the branch current exceeds the set value, and the branch trips.
Malignant load identification: Restrict the access of the branch to the undefined malignant load, and when the branch accesses the unauthorized malignant load (mainly manifested as a large power increment and a large increment factor), the branch trips.
Whitelist identification of vicious loads: allows the specified vicious loads to use electricity normally, such as water dispensers.
Air conditioning mode: In air conditioning mode, the meter continuously detects the weak standby current of the air conditioner, and once the air conditioning socket is unplugged, the meter will trip, and the power can only be closed by contacting the management personnel.
Intelligent power-limiting socket identification: It supports the identification of anti-power-limiting sockets, and when the vicious load is connected to the loop through the power-limiting socket, the branch is tripped.
Over-temperature control: When the meter measures the temperature for many times in a row (the number of times can be set) is higher than the set value, the meter trips.
Overvoltage and undervoltage control: When the circuit voltage is higher or lower than the set value for many times in a row (the number of times can be set), the meter trips.
The dormitory power management terminal allows the tripping action except for the air conditioning mode to automatically close. The number of allowed times and the waiting time for tripping can be set.
Note: Prepaid management control, time management control and load management control need to be used in conjunction with the company's prepaid electricity management system.
