In the crop planting process, the temperature and the humidity of soil are monitored, so that the water demand condition of the crop growing environment can be reflected; however, due to the limitation of the monitoring distance and uncontrollable factors of the monitoring conditions, the characteristics of low power consumption, high precision, remote data acquisition, remote parameter adjustment and the like are required to be satisfied in order to truly acquire the water demand condition of the crop real-time growth environment.
However, in a real environment, the crop growth environment is generally far away from, the data transmission and the power supply have great uncertainty, if the authenticity and the persistence of the data are monitored manually for a long time, the reality is not realistic, and if the data acquisition frequency needs to be adjusted, a great deal of manpower and material resources are wasted, and the variable crop growth environment cannot be dealt with.
Currently, publication number CN202583176U discloses a real-time measurement and control system for deep soil humidity, and belongs to the technical field of soil humidity measurement; the data is transmitted by adopting a cable mode, but the cable laying cost is too high facing the long-distance crop growth environment, and great waste is caused. For another example, publication number CN204831358U discloses a portable layered automatic soil and air temperature and humidity monitoring device, which comprises a data collector, a communication device, an air temperature and humidity sensor, a soil temperature and humidity sensor and a signal transmission line, wherein the data collector is in communication connection with the communication device, an input channel is arranged on the data collector, and the air temperature and humidity sensor and the soil temperature and humidity sensor are connected with the input channel of the data collector through the signal transmission line; the communication equipment is a portable computer or a smart phone, and can be connected with the communication equipment in a data manner, but the computer or the smart phone cannot be observed in real time, and even if abnormal data are received, corresponding parameter adjustment cannot be performed. The prior researches show that the system and the method for acquiring the temperature and humidity of the soil are successfully prepared at present, but the defects of high use cost, low sensitivity, poor stability, poor precision and the like are generally overcome.
Therefore, the utility model considers the combination of the crop growth environment, monitors the soil temperature and humidity, and can remotely regulate and control the collection frequency according to the needs so as to reflect the water demand condition of the crop growth environment.
