Embodiment 1

[0030] This embodiment provides a plant-following environmental parameter monitoring system, as shown figure 1 As shown, each wireless sensor network in the system includes a number of sensor nodes 1, a number of router nodes 2, a coordinator node 3, a host computer 4, and a field alarm device 5. Sensor node 1 is installed on the conveyor belt 6 in the factory building, which can measure the ambient temperature in real time, with a monitoring accuracy of ±0.5°C, and a range of -20°C-80°C; sensor node 1 uses TDOA positioning technology with a positioning accuracy of ±10cm; sensor node 1 uses lithium Battery powered, monitor every 1min. If it does not exceed the allowable range, the result will be reported every 10 times. If it exceeds, the result will be reported immediately; the result reported by sensor node 1 is sent to router node 2 through the 2.4GHz low-power ZigBee wireless network , Its communication distance can reach 500 meters (visible and unobstructed); the router no...

Embodiment 2

[0032] This embodiment provides a plant-following environmental parameter monitoring system. The sensor node 1 is installed in a drug transport vehicle and can measure the environmental temperature and humidity in real time. The temperature monitoring accuracy is ±0.5°C, the range is -20°C-80°C, and the humidity is ±4.5. %RH, range 0-100%RH (non-condensing); sensor node 1 uses MSD-MAP positioning technology with a positioning accuracy of ±50cm; sensor node 1 uses lithium battery power and monitors every 1 minute. If it does not exceed the allowable range, then The result is reported every 5 times of monitoring, and if it exceeds, it will be reported immediately; the result reported by sensor node 1 sends data to router node 2 through the 2.4GHz low-power ZigBee wireless network, and its communication distance can reach 300 meters (the actual communication distance is sensor node 1 The measured distance from the router node 2 in the transportation vehicle); the router node 2 is i...

Embodiment 3

[0034] This embodiment provides a plant-following environmental parameter monitoring system. The sensor node 1 is installed in an incubator for quick-frozen and cold food and beverages, and can measure the ambient temperature and humidity in real time, with a temperature monitoring accuracy of ±0.5°C, and a range of -20°C-80°C. Humidity ±4.5%RH, range 0-100%RH (non-condensing); sensor node 1 uses MSD-MAP positioning technology, positioning accuracy ±50cm; sensor node 1 uses lithium battery power, sensor node 1 uses lithium battery power, every other Monitor once every 3 minutes. If it does not exceed the allowable range, the result will be reported every 20 times. If it exceeds, the result will be reported immediately; the result reported by sensor node 1 is sent to router node 2 through the 2.4GHz low-power ZigBee wireless network, and its communication distance can be Up to 300 meters (the actual communication distance is the measured distance between the sensor node 1 in the ...

Abstract

The invention provides a following-type environmental parameter monitoring system of a workshop. Each wireless sensor network comprises a sensor node, a router node, a coordinator node, an upper computer and an on-site alarming device, wherein the sensor node moves along with a product needing to be monitored to monitor the environmental parameters of the surroundings of the product, the router node is fixed to a static platform, the sensor node works out the self position according to the position of the router node, monitoring data of the sensor node reach the upper computer after passing through the router node and the coordinator node, and if the environmental parameters exceed a permissible range, the upper computer will give an alarming instruction to the on-site alarming device to warn a user. The following-type environmental parameter monitoring system of the workshop has the advantages that the monitoring area is enlarged through the movement of the sensor nodes, the omission risks are reduced, the number of needed sensor nodes is reduced, the effect of enlarging the monitoring area with the low production cost is realized, and the quality of the product is guaranteed.

Description

Technical field [0001] The invention relates to the field of industrial production environment monitoring, in particular to a plant-following environmental parameter monitoring system. Background technique [0002] The current industrial production is becoming more refined, and the requirements for the factory production environment are gradually increasing. Changes in factors such as temperature and humidity, fine particle content, gas concentration, etc. will affect process repeatability, increase the difficulty of product quality control (such as precision agriculture, food, brewing, cosmetics, medicine, textiles, etc.), and cause safety accidents (such as Coal mine, chemical industry, etc.). [0003] Fresh cold chain, pastry, baked food, medicine and other industries require raw materials, semi-finished products and finished products to always be stored in an ideal environment. There are clear requirements for the ambient temperature of each process. Abnormal temperature will ...
