Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a sensor-based fresh-keeping temperature monitoring device for agricultural products, which solves the problem that the fixed position of the temperature detection device cannot effectively monitor the temperature inside the fresh-keeping cold storage, which leads to the frequent maintenance of the fresh-keeping cold storage. Starting and shutting down the refrigeration unit will increase the loss of the unit, reduce the service life of the refrigeration unit, increase energy consumption, and increase storage costs

Abstract

The invention discloses agricultural product fresh-keeping temperature monitoring equipment based on a sensor, the agricultural product fresh-keeping temperature monitoring equipment comprises a temperature monitoring system and a monitoring frame, the temperature monitoring system is bidirectionally connected with a central processing module, and the invention relates to the technical field of agricultural product fresh-keeping. According to the agricultural product fresh-keeping temperature monitoring equipment based on the sensor, the temperature sensor is installed on the conveyor belt with the changeable position, so that the temperature sensor can continuously conduct movable temperature monitoring, more accurate temperature identification is achieved in the mode that the monitoring area is increased, the effective service life of a refrigerating unit is ensured, and the storage cost is reduced; and the temperature values monitored by the temperature sensors are compared in a difference value comparison mode, whether the temperature in the refrigeration house is constant or not is judged according to the fluctuation quantity of the values monitored by the temperature sensors, then the fresh-keeping quality of the agricultural products during storage is guaranteed, and three sets of temperature sensors are arranged, and the occurrence of monitoring errors can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping of agricultural products, in particular to a sensor-based temperature monitoring device for fresh-keeping of agricultural products. Background technique [0002] The preservation of agricultural products is very important. The market is flooded with some low-quality preservatives, which cannot ensure the green environment of agricultural products. Some places with good conditions can not rely too much on preservatives. The "earth method" can still achieve a good fresh-keeping effect. One is to put the picked fruits and vegetables in the earth cold storage to cool down and pre-cool, and then add ice bottles to the fruit and vegetable truck and cover them with insulation quilts. Very good fresh-keeping effect, transporting high-grade fruits and vegetables, you can use the physical fresh-keeping mode, use multi-layer fresh-keeping bags and fresh-keeping boxes for fresh-keeping, and the effect i...
