Intelligent control system for industrial electric flat bogie wagon

Abstract

The invention discloses an intelligent safety control system for an industrial electric flat car. The power supply is depressurized by a low-voltage power supply device and then sent to the track. The boosted power supply device on the flat car takes power from the track and boosts the voltage. Send it to the motor of the electric flat car, and the control power supply device takes power from the boost power supply device and sends it to the signal sampling device and the intelligent controller respectively, and the intelligent controller receives the output signal of the signal sampling device and then sends the control signal to the driving device and the braking device The motor of the electric flat car is controlled, and the braking device takes power from the track and then sends DC power to the motor of the flat car to achieve braking. The electric flat car has sound and light warning function when it is moving, and it has automatic smooth braking function when it stops to avoid the workpiece on the flat car from moving; it can automatically stop smoothly when it encounters obstacles or track limits during movement, thereby avoiding or reducing equipment accidents or personal accident.

Description

1. Technical field [0001] The invention relates to a safety control system, in particular to a safety control system with certain humanization, intelligence and complete control functions applied to an industrial electric flat car. 2. Background technology [0002] At present, KPD series electric flat cars are widely used in industrial production. Its technology is relatively mature and widely used. However, due to its imperfect control function, there are potential safety hazards. For the control technology of KPD series electric flat car, it is analyzed from the principle of relay control (see attached figure 1 ), in the case of electrification, the electrical action control process of the electric flat car is as follows: [0003] 1. Self-locking state: [0004] When the switch SA is turned on, press the button SB4 or SB5, the contactor KM1 or KM2 is attracted and self-locked, at this time, the motor of the flat car is energized, and the flat car moves forward or backwar...

AI Technical Summary

Problems solved by technology

[0009] 1. There is no automatic stable braking unit. When the flat car motor loses power and stops, the flat car will still slide due to inertia;

[0010] 2. In the contactor KM1 or KM2 control circuit, there is no limit switch and safety anti-collision electrical protection device

[0012] 1. During the forward or backward process of the electric flat car, if there are moving or stationary obstacles near the front or rear of the flat car, it is easy to cause collision, injury or damage accidents;

[0013] 2. There is no limit protection during the forward or backward process of the electric flat car. When the flat car moves to the limit of the track and breaks out of the track boss, it is easy to cause equipment accidents such as serious deformation and damage to the low-voltage sliding conductor of the flat car.
