Embodiment

[0016] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] see figure 1 , PIC32MX250F128D MCU is respectively connected with power supply, clock module, FLASH, indicator light, display, keyboard, RS232 data interface, RJ45 Ethernet port, E1 / G.703 interface;

[0018] RS232 data interface, RJ45 Ethernet port, E1 / G.703 are respectively connected to the transmission terminal.

[0019] see figure 2 , the working process of the present invention is, turn on the equipment, after initialization, scan the keyboard of the input module and output the display, test the data of the input interface of various channels, judge the fault, and then enter the protocol analysis function to monitor and analyze the message.

[0020] Take the most widely used 101 protocol and 2M telecontrol channel as examples to illustrate the working process of detecting a specific fault:

[0021] The master station reports a ...

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 [0001] The invention relates to a remote control channel fault detection device, in particular to a portable remote control channel fault detection device for accurately judging the electric remote control channel fault. Background technique [0002] In order to perform accurate fault diagnosis on 232 digital channels, 2M digital channels and network channels, as well as detect and analyze messages, bit error detectors, telecontrol signal analyzers, power E1 dedicated line MODEMs, and notebook computers are commonly used. The above instruments can realize all kinds of current electric telecontrol channel tests, but different instruments need to be used for different detections, resulting in a large number of instruments, and each instrument is also large in size, extremely inconvenient to carry and operate, and low in efficiency. Contents of the invention [0003] In view of the problems existing in the above-mentioned prior art, the present invention pro...
