Problems solved by technology

[0005] In the process of actual use in industrial sites, during PLC maintenance or when adding new peripherals, due to the harsh environment of the industrial site and the heavy wiring workload, it is inevitable that wiring errors will occur, and the power-limited I / The O port is misconnected and short-circuited, causing the port to be over-current and burned. In this case, the wrong connection is fatal, and it is easy to cause a short circuit of the device and cause damage to the components, and even cause a fire.

specific Embodiment 1

[0038] Specific embodiment one: please refer to Figure 1-11 The wiring device, the wiring includes a pressing unit 1, a wiring unit 2, an on-off unit 3 and a control unit 4.

[0039] The pressing unit 1 includes a pressing plate 101 and a plurality of pressing holes 102 , and the pressing holes 102 are opened on the right side of the pressing plate 101 and pass through the pressing plate 101 .

[0040] The wiring unit 2 includes a junction box 201 and a plurality of wiring through holes 202 . A plurality of connection holes 202 run through the left and right side walls of the junction box 201 . The upper end of the junction box 201 is detachably connected to the lower end on the left side of the pressing plate 101, and the pressing holes 102 correspond to the wiring through holes 202 one by one, and each pressing hole 102 and the corresponding wiring through hole 202 are located on the same axis.

[0041] Each wire 6 can only be electrically connected to the terminal 501 of...

specific Embodiment 2

[0057] Embodiment 2: Different from Embodiment 1, the on-off assembly 302 includes more than three baffle plates 302-2 and one activation plate 302-1.

[0058] The structure of the baffle 302-2 is consistent with that in the first embodiment.

[0059] The number of lower outlets 303 and moving slots 304 provided on the lower side of the on-off box 301 is consistent with the number of baffles 302-2.

[0060] The connection relationship between the baffle plate 302-2, the lower outlet 303 and the moving slot 304 is the same as that in the first embodiment.

[0061] The sequential opening of multiple wiring through holes 202 can be realized, which provides guarantee for the wiring operation of the complex PLC system.

specific Embodiment 3

[0062] Specific embodiment three: different from specific embodiment one, the on-off assembly 302 includes a plurality of iron plates, and the lower end of the on-off box 301 is provided with a corresponding number of outlets, the width of the outlets is greater than the width of the iron plates, and the number of iron plates is related to the wiring through holes. 202 correspondence.

[0063] The upper end of each wiring through hole 202 is provided with an electromagnet, the electromagnet is electrically connected with the sensing module 402, a controller is arranged between the electromagnet and the sensing module 402, the controller is electrically connected with the sensing probe 401, and the electromagnet is connected with the sensing module 402. Iron plate magnetic connection.

[0064] When the induction probe 401 senses that the measured electric wire 6 is connected correctly, the controller controls the electromagnet in the next sequence to be de-energized, and the ma...

Abstract

The invention discloses a PLC system for intelligent control of major engineering, and belongs to the field of electrical equipment. The PLC system for intelligent control of major engineering comprises a wiring device. The wiring device comprises a pressing unit, a wiring unit, an on-off unit and a control unit. The wiring unit comprises a plurality of wiring through holes, and each wire can be electrically connected with a binding post of a to-be-wired PLC system only through a single corresponding wiring through hole. The pressing unit comprises a plurality of pressing holes, each pressing hole corresponds to one wire, and the wires can be fixed only through the pressing holes. The on-off unit is used for opening and closing the wiring through holes. The control unit is used for sensing whether the wired wires are electrified. The flexibility of wiring operation can be reduced, wiring can be carried out only in a single channel, whether wiring is correct or not can be checked in time, and faults and accidents are effectively prevented.

Description

technical field [0001] The invention belongs to the field of electrical equipment, and more specifically relates to a PLC system for intelligent control of major projects. Background technique [0002] PLC technology is also relatively cumbersome and complicated, including the design, installation, testing, wiring, etc. of many devices, which must be carefully and carefully. If the PLC control cabinet is connected incorrectly, it will cause a certain degree of damage. [0003] A notable feature of PLC is that there are many I / Os, which means that PLC has strong adaptability. Even if the user changes the control flow chart due to factors such as product replacement, usually only need to modify the control flow chart without modifying the PLC. Hardware wiring, so PLC is widely used in industrial control sites. [0004] Classified from the composition structure, PLC can be divided into two categories: one is integrated integral PLC, which is characterized by the integration of...
