Abstract
The invention relates to a portable device for accurately judging the failures of a telemechanical channel. The portable device comprises a single chip machine. The single chip machine is connected with a power supply, a clock module, a FLASH, an indicating lamp, a display, a keyboard, a RS232 data interface, a RJ45 ethernet and an E1/G.703 interface. The portable device is small in volume, has stable and reliable performance and multiple functions, supports the RS232 data interface, the RJ45 ethernet interface and the E1/G.703 interface and various circulation and question-and-answer type protocols and is used for receiving the protocols to detect the failures and analyze the message. Each protocol supports a plurality of commonly-used default downlink message and also supports the user-programmed downlink message. The portable device can logs into a router and a switch for network communiation to detect the failures.
Description
Technical field
The present invention relates to a kind of telecontrol channel failure detector, relate in particular to a kind of for accurately judging the portable telecontrol channel failure detector of power remote channel failure.
Background technology
For 232 digital channels, 2M digital channel and network channel are carried out accurately failure diagnosis, and to the packet check analysis, generally use Error Detector, remote motion signal analyzer, electric power E1 special line MODEM, notebook computer.Above instrument can be realized present various power remote lane testings, but need to use different instruments for different detections, cause the instrument of needs numerous, and the volume of each instrument is also large, carries, operates extremely inconvenience, and efficient is low.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, a kind of portable telecontrol channel failure detector is provided, solved and to have used different instrument problems for different detections in the prior art, the present invention has gathered 232 digital channels, 2M digital channel, network channel is tested and message monitoring analysis function, and integrate Error Detector, remote motion signal analyzer, electric power E1 special line MODEM, notebook computer, but while sense channel message.
To achieve these goals, the technical solution used in the present invention is:
Comprise single-chip microcomputer, described single-chip microcomputer is connected with power supply, clock module, FLASH, indicator light, display, keyboard, RS232 data-interface, RJ45 Ethernet interface, E1/G.703 interface respectively.

Fig. 1 is structural representation block diagram of the present invention.
Fig. 2 is workflow schematic block diagram of the present invention.
Embodiment
Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, the PIC32MX250F128D single-chip microcomputer is connected with power supply, clock module, FLASH, indicator light, display, keyboard, RS232 data-interface, RJ45 Ethernet interface, E1/G.703 interface respectively;
RS232 data-interface, RJ45 Ethernet interface, E1/G.703 are connected with transmission terminal respectively.
Referring to Fig. 2, workflow of the present invention is, opening device, after the initialization, keyboard and the output display of scanning input module, to the data of various passage input interfaces test, fault judges, enters the protocol analysis function again, he carries out the message monitoring, analyzes.
Course of work when explanation detects a concrete fault as an example of 101 maximum stipulations of present application, 2M telecontrol channel example:
Main website quotes some transformer stations operating mode and withdraws from, the 2M telecontrol channel directly is connected on the E1/G.703 interface of portable telecontrol channel failure detector at the main website end, the button choice menus is selected 101 stipulations, the test of 2M telecontrol channel, checkout gear sends the default message that sets, and automatically judges prompting " ok " according to the message that returns, illustrate that then the message that returns is correct, factory's station end and passage are all no problem, are the problems of main website, and for example main website front panel fault causes.If there is not message to return, then that prompting is " No message ", need to standing to factory, end is further to be tested, the E1/G.703 interface of factory's station end is linked to each other with the E1/G.703 interface of portable telecontrol channel failure detector, operating procedure is the same, prompting " ok " illustrates that then factory's station end equipment is no problem, and can judge is channel failure.
