Abstract
The invention discloses a large-power rectification cabinet water-cooled bus real-time monitoring system. A water inlet end and a water outlet end of a water cooling copper bar are respectively provided with a temperature sensor. The temperature sensors are connected with a single-chip microcomputer through optoelectronic isolators. The single-chip microcomputer is connected with a computer through a MAX232 module. Data transmission is performed through a MODBUS communication protocol. A power supply module supplies power to the single-chip microcomputer. The single-chip microcomputer is connected with a first LED and a second LED respectively. Tested temperatures are digitally displayed by the first LED and the second LED. The optoelectronic isolators isolate partial signals which are collected by the temperature sensors and are liable to be disturbed, and only effective signals are sent to the single-chip microcomputer. The large-power rectification cabinet water-cooled bus real-time monitoring system has the advantage that the large-power rectification cabinet water-cooled bus real-time monitoring system is capable of accurately measuring the temperature of a large-power rectification cabinet water-cooled bus in real time.
