Embodiment 1

[0026] Such as figure 2 As shown, a kind of scheduling automatic master station channel plate testing device of the present invention, it comprises network cable 1 and network cable connector 2; One end of described network cable 1 connects RJ45 crystal head 11, and the other end corresponds to 1 and 3 pins of RJ45 crystal head The wires of the feet are connected; the RJ45 crystal head 11 is connected to the male head of the network cable connected to the channel board through the network cable connector 2. Wherein, the RJ45 crystal head 11 of the network cable 1 is manufactured according to the 568A standard, and the white-orange wire 12 at the other end is connected to the white-green wire 13 .

Embodiment 2

[0028] A kind of scheduling automatic master station channel plate testing method of the present invention, it comprises the following steps:

[0029] Make test tools;

[0030] Use test tools to connect the receiving and sending channels of the channel board to form a loop;

[0031] Judge whether the channel of the channel board is good or bad by observing the message status of the system workstation and the receiving and sending indicators on the panel of the channel board.

[0032] In the above method, the connection of the receiving and sending channels of the channel board is to connect the test tool with the network cable of the channel board through the network cable connector.

[0033] In the above method, the judgment of whether the channels of the channel board are good or not is by observing whether the receiving and sending indicators on the channel board are flickering normally, and whether the loop message of the system workstation is received normally. The proc...

Abstract

The invention relates to a dispatching automation master station channel plate testing method and device. The dispatching automation master station channel plate testing method includes the steps of manufacturing a testing tool, using the testing tool to be connected with a receiving channel and a transmitting channel of a channel plate so as to form a loop, and judging the state of a channel of the channel plate by observing a receiving indicating lamp on a panel of the channel plate, a transmitting indicating lamp on the panel of the channel plate and message receiving situations of a loop of a system workstation. The dispatching automation master station channel plate testing device comprises a reticle and a reticle connector. One end of the reticle is connected with an RJ45 crystal end, a wire of a first pin and a wire of a third pin at the other end of the reticle are connected, and the first pin and the third pin correspond to the RJ45 crystal end. The RJ45 crystal end is connected with a reticle male end through the reticle connector, or the RJ45 crystal end is directly connected with a reticle female end. According to the dispatching automation master station channel plate testing method and device, the operation is easy to achieve, the channel plate testing work can be carried out by a single person, the channel testing is simple and rapid and convenient to achieve, and the possibility of error operations is reduced. The low-cost testing device and the simple testing method are adopted, so that the operation and maintenance cost is reduced, and the channel plate testing work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of substation automation, in particular to a method and device for testing a channel board of a scheduling automation master station. Background technique [0002] The power system dispatching automation master station is responsible for substation data reception and master station control command issuance. The channel board is an important hardware component of the master station of each dedicated line channel, and its operating status directly determines the operating status of the channel. Such as figure 1 As shown, the working mode of the optical fiber digital channel from the substation to the main station is: the general control equipment of the substation transmits the signal to the communication digital distribution frame (PCM) through the network cable, and after passing through the optical transceiver (SDH), the signal is converted into an optical signal, and then passed through The optical distri...
