It first turns on for the lasting detection function needs of temperature sensor existing in the prior art and continues to open and follow
The problems such as ring pump is just able to achieve, and power consumption is big, easily causes the wasting of resources, the utility model provides a kind of temperature of cooling equipment
Detection device is spent, the lasting inspection of chilled liquid temperature in cabinet can be realized without first turning on and continuing unlatching circulating pump
Survey, consume energy it is low, the energy can be greatlyd save.
A kind of temperature-detecting device of cooling equipment comprising cabinet, compressor, in the cabinet inject cooling water or
Cooling oil is equipped with circulating pump in the cabinet, which is characterized in that and the lateral wall of the cabinet is equipped with temperature sensor T1,
The input terminal of the temperature sensor connection signal input circuit, the output end and cpu controller U1 of the signal input circuit
Connection, the cpu controller U1 are also connect with the circulating pump, compressor respectively.
It is further characterized by,
The model of the cpu controller U1 are as follows: PIC18F66K40；
The signal input circuit includes temperature sensor T1, the temperature sensor T1 by connector CN3 with it is described
Cpu controller U1 connection, 1 pin of the connector CN3 are separately connected 2 pins of one end of resistance R1, the connector CN3
Be separately connected 27 pins of the cpu controller U1, one end of resistance R2, after the other end connection of described resistance R1, R2 with electricity
Potential source VCC connection, the cpu controller U1 24 pins connection resistance R3 one end, the other end of the resistance R3 with it is described
It is grounded after the 3 pins connection of connector CN3；
Cpu controller U1 connection alarm lamp 2, one end of the 3 pins connection resistance R4 of cpu controller U1, the electricity
Hinder the anode of the other end connection Light-emitting diode LED 1 of R4, the minus earth of the Light-emitting diode LED 1；
44,45 pins of the cpu controller U1 pass through contactor K1, K2 respectively and circulating pump, compressor connect.
Using the above structure of the utility model, temperature sensor is installed on to the lateral wall of cabinet, easily operated personnel
The temperature regime of liquid in the live cabinet of observation in time；It can ensure that temperature signal keeps stablizing in signal input circuit, temperature letter
Number digital signal is converted to through the A/D conversion module in cpu controller U1, cpu controller U1 is controlled after receiving digital signal
Circulating pump and compressor start and stop operation, can be achieved under the situation without starting circulating pump first to liquid in cabinet
The setting of the lasting detection of temperature, temperature sensor T1 and cpu controller U1 have maximally reduced the turn on pump of circulating pump
Time greatly reduces the power consumption of circulating pump, has saved the energy.
Detailed description of the invention
Fig. 1 is the circuit structure block diagram of the utility model；
Fig. 2 is the circuit diagram of the signal conversion circuit of the utility model.
Specific embodiment
As shown in Figure 1 and Figure 2, a kind of temperature-detecting device of cooling equipment comprising cabinet, compressor are infused in cabinet
