Project overview
In 2024 Tongwei supplied metered billing and prohibited-load monitoring for a key university in Henan. The campus needed billing software more than another batch of meters: one system to read, settle and stop prohibited loads. About 640 dorm rooms in four buildings, a dozen shops and one sports hall share it. Dorms are prepaid, shops have separate accounts, and the sports hall meters without charging during whitelist class hours. Accounts open as area–floor–room, accept cash, WeChat and campus-card top-up, and bill on the month-end date. Arrears open the breaker; a successful top-up closes it; selected rooms can be kept on. Smart breakers detect prohibited loads locally: air conditioning alone stays on, air conditioning together with a prohibited high-power appliance trips, and items such as water dispensers can be allowed. Each gateway carries about 60 meters and pushes reads, tariffs and open/close commands to the breakers. The software sends balance warnings, bills, top-up receipts and over-power alarms. Finance and operations permissions are separate, and both actions and exceptions are logged.
