Constant-temperature control system of constant-temperature equipment

Abstract

The invention belongs to the technical field of constant-temperature control and discloses a constant-temperature control system of constant-temperature equipment. The constant-temperature control system comprises a temperature sensor, a refrigeration device, a heating device, a control terminal, a processing module, a judging module and a communication module. According to the constant-temperature control system provided by the invention, temperature of the constant-temperature equipment is monitored in real time by adopting the temperature sensor and is compared with upper limit and lower limit of a pre-set temperature range; when the monitored temperature is higher than the upper limit of the pre-set temperature range, the refrigeration device is started to cool the constant-temperatureequipment; when the monitored temperature is lower than the lower limit of the pre-set temperature range, the heating device is started to raise the temperature of the constant-temperature equipment.The control terminal can be used for remotely modifying various working parameters and controlling refrigeration or heating; if the monitored temperature exceeds the pre-set temperature range, monitored temperature information is transmitted to the control terminal and a worker can conveniently grasp real-time conditions.

Description

technical field [0001] The invention belongs to the technical field of constant temperature control, and in particular relates to a constant temperature control system of constant temperature equipment. Background technique [0002] Existing heat preservation systems often use relays as the main temperature control components, because relays can directly drive 2500W power loads, and are suitable for small-power electrical equipment such as homes and small factories, and have a wide range of application directions. The alarm components of electrical components are mostly realized by buzzers, and LED lights indicate the corresponding heating or cooling working status. [0003] The temperature control system of this thermal insulation system is simple in structure, low in cost, and relatively simple and self-assembled. When working, if the temperature is higher or lower than the set temperature, the buzzer will alarm and remind. If the temperature is lower than the lower limit...
