Embodiment 1

[0026] This embodiment provides a plant follow-up environmental parameter monitoring system based on a wireless sensor network, as shown in the schematic figure 1 As shown, each wireless sensor network in the system includes several sensor nodes 1 , several router nodes 2 , a coordinator node 3 , a host computer 4 and a field alarm device 5 . The 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; the sensor node 1 uses TDOA positioning technology, and the positioning accuracy is ±10cm; the sensor node 1 uses lithium Battery-powered, monitor once every 1 minute, if it does not exceed the allowable range, report the result every 10 times, if it exceeds, report immediately; sensor node 1 reports the result and sends data to router node 2 through the 2.4GHz low-power ZigBee wireless network , its communication distance can reach 500 meters...

Embodiment 2

[0028]This embodiment provides a plant-following environmental parameter monitoring system based on a wireless sensor network. The sensor node 1 is installed in a drug transport trolley, which can measure the ambient temperature and humidity in real time. The temperature monitoring accuracy is ±0.5°C, and the range is -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 supply, monitor once every 1min, if not If it exceeds the allowable range, the result will be reported every 5 times of monitoring, and if it exceeds, it will be reported immediately; the sensor node 1 will send the data to the router node 2 through the 2.4GHz low-power ZigBee wireless network, and its communication distance can reach 300 meters (actual communication The distance is the measured distance between sensor node 1 and router node 2 in the transport trolley); router node...

Embodiment 3

[0030] This embodiment provides a plant-following environmental parameter monitoring system based on a wireless sensor network. The sensor node 1 is installed in an incubator for quick-frozen and cold food, and can measure the ambient temperature and humidity in real time. The temperature monitoring accuracy is ±0.5°C and the range is -20 ℃-80℃, 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 supply, sensor node 1 uses lithium Battery-powered, monitor once every 3 minutes, if it does not exceed the allowable range, report the result every 20 times, if it exceeds, report the result immediately; sensor node 1 reports the result and sends data to router node 2 through the 2.4GHz low-power ZigBee wireless network , its communication distance can reach 300 meters (the actual communication distance is the measured distance between sensor node 1 in the incubator a...

Abstract

The invention provides a workshop following type environmental parameter monitoring system based on wireless sensor networks. Each wireless sensor network comprises a sensor node, a router node, a coordinator node, an upper computer and an on-site alarm device. The sensor nodes move along with products needing to be monitored to monitor the environmental parameters of the surroundings of the products, the router nodes are fixed to a static platform, the sensor nodes work out the positions of the sensor nodes according to the positions of the router nodes, monitoring data of the sensor nodes reach the upper computers after passing through the router nodes and the coordinator nodes, and if the environmental parameters are beyond a tolerance range, the upper computers issue alarm instructions to the on-site alarm devices to warn users. The system has the advantages that the monitoring area is increased through movement of the sensor nodes, the omission risk is reduced, the number of needed sensor nodes is reduced, and therefore the effect of increasing the monitoring area at a low production cost is achieved, and the product quality is guaranteed.

Description

technical field [0001] The invention relates to the field of industrial production environment monitoring, in particular to a plant follow-up environmental parameter monitoring system based on a wireless sensor network. Background technique [0002] The current industrial production is becoming more and more refined, and the requirements for the production environment of the factory are gradually increasing. Changes in factors such as temperature and humidity, fine particle content, and gas concentration 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 mines, chemicals, etc.). [0003] Fresh cold chain, pastry, baked food, pharmaceutical and other industries require raw materials, semi-finished products and finished products to be kept in an ideal environment at all times. There are clear requirements for the ambi...
