Problems solved by technology

[0006] ①It can only judge whether the cable is on or off, and the cable code verification needs to be completed by wireless communication equipment. Due to the influence of the electromagnetic environment and the site (such as: remote mountainous areas), it is easy to make mistakes in the cable code verification
[0007] ② Electromagnetic waves generated by wireless communication equipment will interfere with the automation equipment in the comprehensive control room of the substation, causing malfunction and affecting the safe operation of the power grid, and the use of wireless communication equipment is currently prohibited in the comprehensive control room of the substation
[0008] ③Separate operation of line alignment and marking, which affects the accuracy of the secondary circuit wiring of the power system

Embodiment 1

[0029] Such as figure 1 Shown by S, VD MF , VD ZF , E, public land, VD MS , VD ZS , T, and cables can form a loop, which can not only detect the continuity of the cable, but also transmit digital signals. CPU controls VD MF , VD ZF It can realize on-line control, digital signal transmission, VD MS , VD ZS The output is connected to the CPU to realize the reception of on-off signals and digital signals. After booting up, it first enters the line work, the host repeatedly scans the electronic switches (that is, makes S1 to S14 conduction in turn, and only one electronic switch is conducted at each moment), VD MF , VD ZF Set the open state, when the slave probe is connected to one of the 14 cables, a current is generated in the loop to drive VD MS , VD ZS When it is turned on, the output signals are sent to the master and the slave respectively. The master judges which cable is connected according to the position of S, and uses VD MF To control the on-off of the loop,...

Embodiment 2

[0034] Embodiment 2: Same as Embodiment 1, the difference is that the probe (T) is replaced by another group of electronic switches, and this other group of electronic switches includes 14 electronic switches, and the wiring form is connected with the electronic switch at the host end Exactly the same (or symmetrical to each other), one end of the other group of electronic switches is respectively connected to the 14 wires of the cable, and the other end of the other group of electronic switches is short-circuited together and connected to one end of the slave branch. The other end of the slave-to-line branch is connected to the common ground (COM).

Abstract

The invention discloses an intelligent lead aligner which comprises a host machine and a slave machine, wherein the host machine comprises a host machine CPU (central processing unit) and a host machine digital signal transceiver circuit; the host machine digital signal transceiver circuit comprises a first optical coupler for sending a switch signal, a second optical coupler for receiving the switch signal, and a plurality of electronic switches for connecting a plurality of leads at one end of a cable; a code sending unit is arranged in the host machine CPU and is used for sending a lead code corresponding to the successful alignment to the slave machine through the first optical coupler after the host machine and the slave machine are successfully aligned; a slave machine CPU and a slave machine digital signal transceiver circuit are arranged on the slave machine; and the slave machine digital signal transceiver circuit comprises a third optical coupler for sending the switch signal, a fourth optical coupler for receiving the switch signal, and a probe for connecting any one of the leads at the other end of the cable. The intelligent lead aligner has the advantages that alignment is easy to realize and the aligning efficiency is high.

Description

technical field [0001] The invention relates to an intelligent alignment device, which is used for alignment detection of cables. Background technique [0002] Wire alignment devices are widely used in the cable alignment work of the secondary circuit of the power system. At present, there are two types of alignment equipment on the market: [0003] One is a multimeter: it can judge the on-off of the cable, determine whether the cable connection is correct or not, and prompt with the sound of the buzzer. It has strong versatility and low price; but it has a single function, requires many personnel, and needs to be equipped with voice communication equipment to complete the numbering work at both ends of the proofreading cable. [0004] The second type is a dedicated wire alignment device: it can judge the on-off of the cable, determine whether the cable connection is correct or not, and use the light of the light-emitting diode and the sound of the buzzer to prompt. It als...
