[Abstract]:As an indispensable medical equipment in hospital, it is of great significance to detect the electrical parameters of the monitor. Traditionally, the electrical parameters of the monitor need to be detected by third-party equipment, and the detection process is troublesome and the rate of missing detection is high. In this paper, Zigbee wireless network is used to realize real time monitoring of electrical parameters and running status of monitor. Zigbee is a short distance wireless communication protocol, which is characterized by low cost, low power consumption and simple networking. The function of real-time monitoring and communication management of mobile target can be realized in Zigbee wireless network. This paper uses CC2530 chip as hardware base, designs radio frequency module according to Zigbee protocol, and sets up a Zigbee wireless communication network. Firstly, this paper introduces the application of domestic monitor system and electrical safety detection. According to the comparison of wireless communication technology and the analysis of actual demand, the superiority of Zigbee wireless technology is expounded. At the same time, the Zigbee network topology and Zigbee protocol stack are introduced in detail. Secondly, the hardware of Zigbee base station module is designed by using CC2530 chip, and then the embedded principle design scheme is given to monitor the electrical security of monitor. Based on the combination of RSSI ranging algorithm and trilateral location algorithm, the wireless location of moving target is realized. Then, the correlation sparse matrix of signal attenuation coefficient between base stations is established on the host computer, and the optimization of location is realized by using the look-up table method. Then, the client software is designed by using C Sharp language, and a simple and quick interface is designed for the windows such as equipment management, map loading, alarm information statistic query and dynamic real-time monitoring. The requirement of client real-time monitoring is realized. Finally, after relevant tests, the alarm information such as electrical safety and the location of the monitor are satisfactory. The communication can basically meet the requirements of real-time, fast, stable and safe.
