[Abstract]:The indoor temperature of terminal thermal users during heating supply period is an important parameter in the process of heating operation. To monitor the temperature accurately in real time and adjust the operating conditions in time can effectively reduce the phenomenon of complaint or oversupply of heat users and realize the rational control of heat energy. The wireless room temperature acquisition system introduced in this paper consists of a wireless room temperature collector and a monitoring center server. The wireless room temperature collector takes C8051F410 microcontroller as the core and collects the temperature through the DS18B20 digital temperature sensor. The data is sent to the monitoring center server by MG301-LCC GPRS module. The server establishes the outdoor temperature prediction model for the next 5 hours. The operator adjusts the control curve according to the feedback of the predicted outdoor temperature and the user's room temperature change curve. The adjustment parameters of the heat exchange station are issued. During the non-heating period, the device can be set to low power mode in the server, and the anti-displacement warning function is designed according to the principle of accelerometer, which effectively prevents the malicious mobile device from the user and thus affects the actual measurement results.
