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
The invention belongs to the electrical application technology field, relate to a kind of intelligent handheld device, relate in particular to a kind of ruins site environment and monitor special-purpose PDA wireless control system.
Background technology
Can there be following defective in the various field monitoring equipment of in the archaeology process, using at present:
1, lack effective coverage hole detection means, during on-premise network only by rule of thumb with dispose the later data observation method, lack flexibility and real-time.
2, lack flexible parameter modification means, radio node parameter only can lack on-the-spot modification ability through wired mode or through the watch-dog terminal modifications, do not possess flexibility and real-time.
3, lack the field node data and check means, only can observe data at monitor terminal, real-time is relatively poor, can't accomplish point-to-point checking.
Summary of the invention
In order to solve the above-mentioned technical problem that exists in the background technology; The invention provides and a kind ofly lay node through assessing signal intensity and link-quality; Irrational node of some layouts or relaying are made corresponding adjustment, guarantee that the stability of whole wireless network and the ruins site environment of reliability monitor special-purpose PDA wireless control system.
Technical solution of the present invention is: the invention provides a kind of ruins site environment and monitor special-purpose PDA wireless control system, its special character is: said ruins site environment is monitored special-purpose PDA wireless control system and is comprised radio receiving transmitting module.
Above-mentioned ruins site environment is monitored special-purpose PDA wireless control system and is also comprised the serial communication modular that links to each other with radio receiving transmitting module.
Above-mentioned ruins site environment is monitored special-purpose PDA wireless control system and is also comprised the display module that is used to show archaeology process real-time data that links to each other with serial communication modular.
The communication frequency of above-mentioned radio receiving transmitting module is 433MHz.
Above-mentioned serial communication modular is RS232 interface, 485 interfaces, SPI interface or jtag interface.
Advantage of the present invention is:
1, real time monitoring network coverage hole.Hand-held PDA monitoring of equipment network signal provided by the present invention blind area; Near its gateway and relaying of RF receiving and transmission module search of hand-held PDA; And from the packet that feeds back, extract parameters such as signal strength signal intensity and link quality; Be presented at synchronously on the PDA software interface, can avoid like this node is deployed to signal blind zone.When handheld device can detect network, can lay node through assessing signal intensity and link-quality, irrational node of some layouts or relaying are made corresponding adjustment, can guarantee the stability and the reliability of whole wireless network like this.
2, can make amendment to the monitoring node parameter at the scene, degree of flexibility is high, real-time is good.The hand-held PDA equipment that the present invention adopted is given radio receiving transmitting module through RS232 interface transmitting order to lower levels; Radio receiving transmitting module is transmitted to order the monitoring point that will revise; The renewal of making amendment of the parameter that will revise behind the recognition command of monitoring point; Can dispose in real time and revise in the on-the-spot parameter of monitoring, like ID, the length of one's sleep, transmitting power etc. monitoring node.
3, can obtain real time data from formulation with point-to-point mode.The RF receiving and transmission module of the hand-held PDA of the present invention sends instruction near gateway and relaying; The gateway and the via node that receive instruction will be from the PDA equipment that is distributed to that monitors; After PDA equipment is received data, it is presented on the software interface synchronously, can obtains near the data of monitoring point the PDA with point-to-point mode; Reduce volume of transmitted data, have good real time performance and flexibility.

Embodiment
Technical scheme
Referring to Fig. 1, network blind area of coverage detects.Near its gateway and relaying of RF receiving and transmission module search of hand-held PDA, and from the packet that feeds back, extract parameters such as signal strength signal intensity and link quality, be presented at synchronously on the PDA software interface.Revise the monitoring node parameter.Hand-held PDA gives radio receiving transmitting module through RS232 interface transmitting order to lower levels, and radio receiving transmitting module is transmitted to the monitoring point that will revise with order, the renewal of making amendment of the parameter that will revise behind the recognition command of monitoring point.Parameter commonly used has node ID, subnet, channel, the length of one's sleep, transmitting power or the like.Real time data shows.The RF receiving and transmission module of hand-held PDA sends instruction near gateway and relaying.The gateway and the via node that receive instruction will be from the PDA equipment that is distributed to that monitors.After PDA equipment is received data, it is presented on the software interface synchronously.
Referring to Fig. 2; When adopting hand-held PDA provided by the present invention to carry out the network blind area of coverage detection, when hand-held PDA receives the monitoring order, send search message i.e. (broadcast packet) periodically towards periphery through RF receiving and transmission module; If receive the affirmation message that other nodes are sent at the appointed time, the hand-held residing position of PDA is described not in network blind area of coverage, otherwise then explains in the blind area.PDA is according to the message that receives, and the blind area and the quality of the network coverage is presented on the software interface synchronously.
Referring to Fig. 3; When adopting hand-held PDA provided by the present invention to carry out the monitoring node parameter modification; The user at first is provided with the various parameter values of monitoring node on hand-held PDA software interface; After confirming modification, hand-held PDA is sent to RF receiving and transmission module with the relevant parameters configuration order, and transfers commands on the monitoring node that needs the modification parameter through modes such as forwardings.If fail to receive the feedback information of monitoring node at the appointed time, the then synchronous configurations shown failure of software interface, otherwise then configurations shown success synchronously.
Referring to Fig. 4, when adopting hand-held PDA provided by the present invention that real time data is shown, hand-held PDA periodically sends instruction through RF receiving and transmission module near gateway and relaying after receiving the real time data display command that the user sends.The gateway and the via node that receive instruction will return to PDA equipment from the data that monitoring node receives.After PDA equipment is received data, it is presented on the software interface synchronously.
