Project overview
In 2023 Tongwei supplied smart restrooms, corridor smoking control and cleaner attendance for a central hospital in a provincial capital. The hospital name is not published. Restrooms were connected in two phases. The first uses ceiling sensors for occupied or free, indicator units to show that outside the stall, and emergency buttons, four-in-one environment sensing and infrared footfall into the same management host. The later phase extends the same pattern: more stall sensors, indicators, help buttons and environment sensors, with entrance counters for footfall. Together that is 75 ceiling stall sensors, 69 indicator units, 69 emergency buttons, 13 four-in-one environment sensors, 13 footfall counters and 7 management hosts. One platform was built; later devices join the existing platform. The restroom screen shows free stalls for the men's and women's rooms, with temperature, humidity, ammonia, hydrogen sulfide and footfall. Corridor smoking alerts by floor, marking the floor on the building view and keeping a record. Cleaners check in by location, so the screen shows that day's cleaning count and the latest clean. Occupancy, odour, corridor smoking and cleaner attendance can therefore be read on one operations view.
