As shown in Figure 1, the utility model installs a temperature sensor 2 respectively at the water inlet end of water-cooling copper bar 1 and water side, temperature sensor 2 model is that DS1820 replaces 65 DEG C of temperature switches to be directly installed in water, for detecting water inlet end temperature and the water side temperature of water-cooling copper bar 1.
As shown in Figure 2, temperature sensor 2 connects single-chip microcomputer 4 by photoisolator 3,
Temperature sensor 2 adopts 3 pin TO-92 to encapsulate.The function of each pin: GND is voltage ground; DQ is forms data bus; V
cCfor supply voltage.
Single-chip microcomputer 4 connects computer 9 by MAX232 module 5, and by MODBUS communications protocol transmission data, the effect of MAX232 chip is level conversion, the level between conversion Transistor-Transistor Logic level and standard RS232, is convenient to connect computer 9.Power module 6 powers to single-chip microcomputer 4.Single-chip microcomputer 4 connects a LED7 and the 2nd LED8 respectively, by a LED7 and the 2nd LED8 numerical monitor dut temperature.
Temperature sensor 2 is gathered the part signal be easily disturbed come by photoisolator 3 keeps apart, and only useful signal is sent into single-chip microcomputer 4, single-chip microcomputer 4 model is AT89C51.
Be illustrated in figure 3 the circuit catenation principle figure of the utility model system.
Native system follows MODBUS communications protocol, each some temperature can be monitored in real time, temperature accuracy reaches 0.2 DEG C, the utility model can carry out Real-Time Monitoring to water-cooled bus bar copper row temperature in real time, and fault-signal is sent into computer by single-chip microcomputer by MODBUS communications protocol, carry out fault alarm and analysis.
The above is only to better embodiment of the present utility model, not any pro forma restriction is done to the utility model, every any simple modification above embodiment done according to technical spirit of the present utility model, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
