Embodiment 1

[0056] Embodiment 1: as figure 1 The shown industrial equipment and environment monitoring system includes a wireless collector 1 , a wireless gateway 2 , a wireless controller 3 , a base station 4 , a local monitoring terminal 5 , a mobile monitoring terminal 6 and a remote monitoring center 7 . Mobile monitoring terminal 6 and remote monitoring center 7 are to improve monitoring effect better, and mobile monitoring terminal 6 and remote monitoring center 7 can receive the sensing data packet and status message packet that base station 4 sends through mobile Internet / Internet, reach portability monitoring At the same time, the received data can be stored and subsequently analyzed.

[0057] The wireless collector is connected to the external sensor, periodically collects the information of the corresponding industrial equipment or environment, and sends the sensor data to the wireless gateway through the ad hoc network algorithm, and the wireless gateway sends the data to the ...

Embodiment 2

[0098] The wireless collectors in the system are distributed in the monitoring site environment and powered by dry batteries or industrial site infrastructure power supply facilities. After the wireless collector is powered on and initialized, the first wireless transceiver unit enters the listening state. If the wireless collector receives the routing update message packet, it first checks the transmission control field TControl in the message packet, if it receives the message packet of this TControl for the first time, then the h s updated to H s +1, record the ID number of this neighbor node and classify it as H - (a node with 1 less hops than itself to the sink node), the H in the routing update message packet s Broadcast the message after adding 1; if it is not the first time to receive the message packet of the TControl, there is no need to broadcast the message packet again, but the neighbor table information must also be updated.

[0099] After the routing update p...

Embodiment 3

[0111] After the wireless gateway is powered on and initialized, the third wireless transceiver module is in a listening state, waiting for a system start message from the base station. After receiving the base station pre-start message packet, it starts to broadcast the route update message packet, starts the route update timer Timer1, and performs the route update work periodically. The wireless gateway has the function of data exchange and routing selection in the network: if the wireless gateway receives the sensing data packet sent by the wireless collector or wireless controller, it will forward it to the base station; if the wireless gateway receives the sensor data packet sent by the wireless controller The status information packet is also forwarded to the base station; if the wireless gateway receives the control command data packet sent by the base station, it is forwarded to the wireless controller.

[0112] Such as Figure 8 As shown, the workflow of the wireless...

Abstract

The invention discloses a WSN information perception system and method for industrial equipment, agriculture, communication, storage, and living environment monitor. In the system, a wireless collector obtains the sensor data of industrial equipment or environment through corresponding sensor interfaces, then the processed data is sent to a wireless gateway through an ad-hoc network; a wireless controller controls execution equipment according to the received control commands and sends the state information to the wireless gateway; the wireless gateway uploads the received sensor data and the state information to a base station, and transmits the control commands from the base station to the wireless controller; and the base station processes and sends the received sensor data and state information to a local monitor terminal and sends the control commands from the local monitor terminal to the wireless gateway. The local monitor terminal can store and display the collected sensor data and emit the control command, and thus the information collection, wireless transmission, and control of industrial equipment and environment in an industrial scene can be achieved by the system.

Description

technical field [0001] The present invention relates to industrial equipment and environmental monitoring methods such as agriculture, transportation, storage, and living, especially a WSN information sensing system and method used in occasions such as industrial equipment Internet of Things management and control, industrial environment monitoring, and the like. Background technique [0002] At present, the following three methods are mainly used to monitor the status of industrial equipment: (1) offline manual inspection, which is usually adopted by many small and medium-sized enterprises; (2) large and medium-sized enterprises with conditions use wired methods; 3) 2G or 3G public wireless network method. Analyzing the above three methods, it is found that there are the following problems: [0003] 1. Although the offline manual inspection method has certain effects, it lacks real-time, timeliness, accuracy, remoteness, networking and low cost, and has a high rate of fals...
