Usually the heat exchange station mainly adopts human monitoring which does not only waste human resources but also has many hidden dangers. On some control parameter adjustment, manual adjustment has a certain deviation and it is difficult to achieve the ideal running effect. The paper uses PIC single chip microcomputer as the controller core and transmits the collecting data to the monitoring center through GPRS - Internet network. This real-time monitoring system can effectively solve the problem of uneven heating caused by artificial regulate and achieve long-distance wireless remote monitoring and automatic temperature adjustment. It also has the certain energy-saving effect.

The robot control by PC through the wireless communication between the PC and the single-chip microcomputer not only expands the functions of the PC, but also creates more functions of the indoor service robot. Therefore utilization of the wireless communication between the PC and the robot can make full use of resources and improve the efficiency. The hardware of the indoor service robot includes the hardware of the robot control system and the hardware of the PC monitor system. The software of the indoor service robot consists of the software of the PC control software and the single-chip microcomputer control software. Therefore, the robot can autonomously walk along the track or walk under the manual control even when the robot is a long distance away.
