A constant temperature controller for field equipment to operate in severe cold regions

Abstract

The invention discloses a constant temperature controller for helping field equipment to operate in severe cold regions, which includes a mechanical temperature control relay, a power supply connected to the mechanical temperature control relay, a temperature control hysteresis comparator, an optocoupler switch, and a heater. The power input end of the mechanical temperature control relay is connected to the power supply, the normally closed end is respectively connected to the temperature control hysteresis comparator and the optocoupler switch, and the low temperature trigger end is connected to the heater. To solve the problem of using anti-low temperature components to ensure the operation of the entire system, but the cost is relatively high, a constant temperature controller is provided to help field equipment operate in severe cold areas. The good operation of the thermostat overcomes the high cost of traditional measures. Although the present invention uses high-cost low-temperature-resistant devices, the thermostat is used to assist the operation of the entire equipment, so that the equipment itself will save a lot of cost.

Description

Technical field [0001] The present invention relates to an apparatus for assisting in the field of operation, particularly relates to a co thermostat field equipment operating in cold areas. Background technique [0002] In Tibetan areas, difficult terrain, disaster-prone, the mountains temperatures are extremely cold, even up to minus 40 degrees Celsius, and in many cases had to be placed in a number of geological disaster monitoring equipment in these places, these devices can be normal and stable run directly related to the ability to monitor the timely warning and disaster occurred. Traditional measures against this cold case is on the use of anti-low temperature equipment components in the development stage to ensure the operation of the entire system. [0003] The use of traditional technology research and development program, then against the cold of the cost will be enormous, under normal circumstances, the use of slightly better quality low-temperature capacitors, a capa...

Problems solved by technology

[0004] The invention solves the problem of high cost in the prior art of using low temperature resistant components to ensure the operation of the entire system, and provides a constant temperature controller that helps field equipment operate in severe cold areas. When applied in severe cold areas in the field, Cooperating with the incubator, it can effectively ensure the good operation of the equipment and overcome the high cost of traditional measures. Although the present invention uses high-cost low-temperature resistant devices, but the thermostat is used to assist the operation of the entire equipment, then the equipment itself will save go to a lot of cost
