Embodiment 1

[0033] The locomotive toggle switch plug alignment device includes a single-chip microcomputer U1 for signal acquisition of the toggle switch group and a single-chip microcomputer U2 for output control LED display, wherein the single-chip microcomputer U1 is connected with the toggle switch group, and the single-chip microcomputer U2 is respectively connected with the single-chip microcomputer U1 and the indicator light;

[0034] The single-chip microcomputer U1 and the single-chip microcomputer U2 are respectively connected to a crystal oscillator circuit, and the VCC terminals of the single-chip microcomputer U1 and the single-chip microcomputer U2 are connected to a 5V power supply; the RXD terminal of the single-chip microcomputer U1 is connected to the TXD terminal of the single-chip microcomputer U2, and the TXD terminal of the single-chip microcomputer U1 is connected to the RXD terminal of the single-chip microcomputer U2;

[0035] The MCU U1 sequentially scans the input...

Embodiment 2

[0045] Such as figure 2 As shown, the single-chip microcomputer U1 and the single-chip microcomputer U2 adopt the STC8952RC single-chip microcomputer. The locomotive is a HXD1C electric locomotive, and the HXD1C electric locomotive console toggle switch group is the master electrical appliance used to directly operate the locomotive control circuit.

[0046] The HXD1 C-type electric locomotive console toggle switch group controls the locomotive, the main circuit breaker, the pantograph, the compressor, the headlight, the auxiliary light, the marker light, and the driver's cab light. There are seven kinds of equipment in total. The toggle switch is mainly composed of a toggle for the operator to control, a linkage cam, a micro switch group, a connecting wire and a plug. Each controlled function block has a separate cam-microswitch combined structure. According to different functional requirements, the number of control nodes of each group of switches is also different. The ...

Abstract

The invention discloses a locomotive key-lifting switch plug wire calibrator. The locomotive key-lifting switch plug wire calibrator comprises a key-lifting switch group signal acquisition single-chipmicrocomputer U1 and a single-chip microcomputer U2 used for outputting and controlling LED display. The single chip microcomputer U1 sequentially scans the input condition of the switching value ofthe key-lifting switch group, encodes the state of each switch unit to obtain a plurality of state codes, and then adds feature codes to the plurality of state codes respectively to enable each groupof signals to have respective identification features. The coded information is sent to a single-chip microcomputer U2 through serial communication, and the single-chip microcomputer U2 receives the information and compares the information with preset information, and the LEDs distributed on the display panel are lightened or not lightened. The operation can be completed by one person. The test time is shortened to be within 1 minute from the original 20 minutes. The wire calibration accuracy and the wire calibration completion rate can reach 100%. The operation is simple, and the wire calibrator can be used in different environments.

Description

technical field [0001] The invention relates to a cable calibration device for a toggle switch plug of a locomotive. The cable calibration device for a toggle switch plug of a locomotive can be used to verify whether the wiring of a cable is correct after the production of a toggle switch of a railway locomotive is completed. Background technique [0002] With the continuous development of the electrical age, electric locomotives have become an important force in electrical traction. Although the development of science and technology is changing with each passing day, there are still human factors in the actual production and assembly process. The production of products still depends on human operation. [0003] The toggle switch is an important switch group for operating the locomotive. After the toggle switch is manufactured, it is necessary to check whether the wiring points are correct to ensure that the equipment is connected correctly. The structure of the entire tog...
