Background technology
In HWIL simulation turntable electronic control technology, position limitation protection is a very important technology.For some reason
Turret systems have risk out of control, and high speed inertia motion and huge inertia force can be produced when turret systems are out of control, is tied
Collision on structure, often causes structural damage.Common practice is to receive limit switch signal, electromagnetism using electromagnetic relay
Relay inputs a signal into motor driver and motion controller again, and signal is drawn zero by motor driver and motion controller,
Control turntable stop motion.Electromagnetic relay is that coil adds contact, and the response time is slow, and reliability is low, when electromagnetic relay is dynamic
When making, collision is often had occurred that on turntable structure.
The content of the invention
The purpose of this utility model is to provide a kind of a kind of being capable of quick response, HWIL simulation turntable electric limiting
Protection module.
Technical solution of the present utility model is, electric limiting protection module include limit switch, photoelectric coupled device,
Drive circuit, spacing indicator lamp, light coupling relay, motor driver and motion controller, limit switch and photoelectric coupled device
Be connected, photoelectric coupled device output end is connected with the input of drive circuit, the output end of drive circuit and meanwhile with two optocouplers
Relay connects, and the output end of one of light coupling relay connects with spacing indicator lamp and motor driver, another optocoupler
The output end of relay connects with motion controller, and the light coupling relay connected with motion controller is simultaneously defeated with drive circuit
Enter end connection.
Limit switch is the travel switch or proximity switch of open type, to be connected in parallel.
Two described light coupling relays are connected in series, and two light coupling relays are AQW214 or AQW614.
Described photoelectric coupled device is TLP521.
Described drive circuit uses PNP triode S8550.
The utility model has the advantage that and beneficial effect that the utility model uses optical coupling mode, using photoelectricity transmission
Its transmission speed of mode is fast, can realize the fast braking of turntable, and photoelectric coupled device strong antijamming capability, reliability is high, letter
It is single practical, it can be good at the person of being designed and grasp and be applied in actual design.The module can both receive travel switch signal,
Proximity switch signal can also be received, is inputted by photoelectric coupled device, multiple-channel output is realized by light coupling relay, every
