Problems solved by technology

[0003] 1. There is a lack of effective detection methods for coverage blind spots. When deploying the network, it only relies on experience and post-deployment data observation methods, lacking flexibility and real-time performance
[0004] 2. Lack of flexible parameter modification methods. Wireless node parameters can only be modified through wired methods or through monitoring equipment terminals, lack of on-site modification capabilities, and lack of flexibility and real-time performance
[0005] 3. Lack of on-site node data viewing methods, the data can only be observed at the monitoring terminal, the real-time performance is poor, and point-to-point viewing cannot be achieved

Embodiment Construction

[0020] Technical solutions

[0021] see figure 1 , network coverage hole detection. The RF transceiver module of the handheld PDA searches for nearby gateways and relays, and extracts parameters such as signal strength and link quality from the returned data packets, and displays them on the PDA software interface synchronously. Modify monitoring node parameters. The handheld PDA sends a command to the wireless transceiver module through the RS232 interface, and the wireless transceiver module forwards the command to the monitoring point to be modified. After the monitoring point recognizes the command, the parameter to be modified is modified and updated. The commonly used parameters are node ID, subnet, channel, sleep time, transmit power and so on. Real-time data display. The RF transceiver module of the handheld PDA sends commands to nearby gateways and relays. Gateways and relay nodes that receive instructions will distribute the monitored information to PDA devices....

Abstract

The invention relates to a PDA wireless control system specially for monitoring an on-site environment at a site. The system comprises a wireless transceiver module. According to the invention, a PDA wireless control system specially for monitoring an on-site environment at a site is provided; nodes are laid by estimating signal intensity and a link quality; and corresponded adjustment on nodes or relays is carried out, wherein the layout of the nodes or the relays are not reasonable; therefore, stability and reliability of a whole wireless network can be ensured.

Description

technical field [0001] The invention belongs to the technical field of electronic applications, and relates to an intelligent hand-held device, in particular to a special PDA wireless control system for on-site environment monitoring of ruins. Background technique [0002] The various on-site monitoring equipment currently used in the archaeological process will have the following defects: [0003] 1. There is a lack of effective detection methods for coverage blind spots. When deploying the network, it only relies on experience and post-deployment data observation methods, lacking flexibility and real-time performance. [0004] 2. Lack of flexible parameter modification methods. Wireless node parameters can only be modified through wired methods or through monitoring equipment terminals, lacking on-site modification capabilities, and lack of flexibility and real-time performance. [0005] 3. Lack of on-site node data viewing means, the data can only be observed at the moni...
