Problems solved by technology
Install a single-rod temperature probe point at the position that needs to be detected, and the inspector detects and records the temperature of each point through a handheld temperature detector. The disadvantage of this method is that it requires a lot of manpower, and mistakes and missed readings often occur. situation, and this method does not have any characteristics of information monitoring, data storage and analysis cannot be realized, let alone remote monitoring

Embodiment Construction
[0016] The present invention will be further described below in conjunction with the drawings.
[0017] Such as figure 1 As shown, the present invention is that the temperature sensor sends temperature data to the data collection wireless terminal through the connection line. The data collection wireless terminal uses the wireless sensor network system formed by the wireless network router to transmit the collected data to the wireless network base station. The wireless network base station uses Intcrnct The / GPRS network sends data to the network with the designated IP address, and the temperature monitoring server (in this embodiment uses a computer installed with DX-SEWMS 1.0 temperature monitoring software) connects to the network and receives the data. The data collection wireless terminal is between the wireless network router There is wireless two-way digital communication between the wireless network router and the wireless network base station, and the communication frequ...

The invention relates to the field of temperature monitoring based on wireless sensor network technology, and discloses a wireless remote stored-grain temperature monitoring system with low energy consumption, easy maintenance, and multi-path acquisition. The invention is realized through the following scheme: the system comprises a wireless terminal system, a wireless network router, a wireless network base station, and a temperature monitoring server; the data acquisition wireless terminal is provided with a 15-path analog signal switch inside, and a temperature sensor transmits temperature data to the analog signal switch through a connecting wire; the data acquisition wireless terminal, the wireless network router and the wireless network base station perform bidirectional digital communication through a connector and a wireless radio frequency module. The invention solves the problem of wired network dependency of traditional stored-grain temperature monitoring systems, substitutes single-path temperature measurement with multi-path temperature acquisition, not only reduces communication cost and personnel labor intensity, but also improves timeliness and accuracy of temperature monitoring.
Description
Technical field [0001] The invention relates to the field of temperature monitoring, in particular to a wireless remote storage grain temperature monitoring system based on wireless sensor network technology. Background technique [0002] Grain storage is an important link in the field of grain circulation. In the process of grain storage management, the most important thing is the monitoring of grain temperature. Grain ripening, excessive moisture, high levels of pests, microorganisms, and impurities will cause the grain temperature to rise. Under the condition of ensuring the quality of the grain in the warehouse, pests and microorganisms are the main factors that cause the grain temperature to rise. Pay close attention to the grain temperature. Early detection of grain temperature rise is an important task for good grain storage management. The main purpose of temperature monitoring of stored grain is to detect the early rapid rise of local grain temperature, focusing on prev...
