I. Case Overview
As the temperature in the north gradually decreases, the heating season comes. Floor heating is also becoming more and more common in our lives. Today's houses are designed with pipe wells in the stairwell, and the main valve of each floor heating will be on these pipes. In order to inquire whether the households who have not paid the heating fee have stolen the valve or the valve is leaking, a timely notice is issued. The heating company needs the staff responsible for opening and closing the valve every year to go to every household to open and close the valve regularly, which consumes manpower and time. A lot of resources are wasted, and there are also great security risks.
At present, a company in Shijiazhuang mainly manages the local heating supply. Previously, the traditional management of heating valves has been using traditional methods, such as online monitoring of valve status, remote analysis of valve failures, and remote control of valve switches. It requires people to go to the site for operation, which is inefficient and has high labor costs. The customer hopes to establish a heating valve online monitoring system to monitor the valve status remotely and analyze the cause of valve failure.
As an industrial Internet of Things service provider integrating R & D and intelligent manufacturing capabilities in the Yangtze River Delta region, MANTOO has developed a collection of wireless data transmission and automatic control technology with remote relay controllers according to the company ’s needs. Data collection and automatic control functions are integrated heating remote online monitoring management system. The product helped the company solve the problem of real-time monitoring of heating valves, which enabled the company to greatly improve staff efficiency, save costs, and effectively improve management capabilities.
