Wireless temperature acquisition device with reversal connection protection function

Abstract

A wireless temperature acquisition device with a reversal connection protection function comprises a single-chip microcomputer, a temperature acquisition module, a wireless data transmit-receive module, a power supply module, a reversal connection prevention protection module and two control switches. The reversal connection prevention protection module is connected between the single-chip microcomputer and the power supply module. The single-chip microcomputer comprises a timer, an AD conversion module and a microprocessor. The microprocessor is connected with the timer and the AD conversion module at the same time. The temperature acquisition module and a wireless communication module are connected with the microprocessor respectively through a control switch. The temperature acquisition module is connected with an input end of the AD conversion module. The wireless data transmit-receive module is connected with the microprocessor. According to the invention, the single-chip microcomputer precisely calculates the working period of each module and controls the power supplying modes of the wireless data transmit-receive module and the temperature acquisition module, so that the power consumption of the system is reduced, the electric energy is saved, and the continuous working time of the device is prolonged; in addition, the reversal connection prevention protection module is connected between the single-chip microcomputer and the power supply module, so that the reliability of the whole device is improved.

Description

technical field [0001] The invention relates to the technical field of data collection, in particular to a wireless temperature collection device with a reverse connection protection function. Background technique [0002] Temperature measurement is widely used in power systems. The traditional temperature measurement method is wired digital temperature monitoring, but because this method relies on wired data transmission, it limits the monitoring environment to a large extent. In certain occasions, the monitoring points are scattered, the environment is closed or there is high voltage. Many measurements The method cannot realize the measurement work at all, and laying a large number of cables also causes a waste of resources. So wireless temperature measurement technology came into being. [0003] In the process of wireless temperature measurement, the data collected by the wireless communication module needs to be sent out, and the wireless communication module needs to ...
