Concrete pump truck to achieve wireless remote control technology principle:
The use of wireless remote control technology, to a greater extent reflects the high efficiency of construction, in the complex site, the use of mature wireless remote control technology, handheld wireless communication equipment, control the controlled end used to control the slow rotation of the switching solenoid valve.
Pause, resume and pause buttons are used to pause the stirring rotation state being executed, and restore the stirring rotation state value being executed before suspension. Clearing this function can be negotiated; Acceleration, deceleration, used to control the engine throttle size, analog quantity execution, a key for control of analog quantity increase, a key for control of analog quantity decrease, corresponding analog quantity output execution of 4-20mA or 0-10V or other control range; Mixing, discharging, these two actions should be the switching mode, both of them are self-locking mode, and they do not set the interlocking logic.
There are 13 buttons on the panel, which are: start, emergency stop, mixing mode, transportation mode, recovery, pause, cleaning, acceleration, deceleration, mixing, discharging, sliding up, sliding down. A digital tube or LCD display. It is used to display the speed of the mixing pump body collected by the sensor at the feedback receiver, and the sensor for collecting is provided by the purchaser. Take the start + emergency stop function as an example, it is mainly used to start the remote control system, and at the same time the main relay at the receiver is closed. Emergency stop is used to close the remote control system, and at the same time the main relay at the receiver is disconnected, and the total power supply of the controlled device is disconnected.
Mixing mode, transportation mode, the two self-locking mode is implemented, corresponding to the output of two relays, and the two are interlocked. The function button of mixing mode is regarded as fast rotation, corresponding to the switch solenoid valve used to control the fast rotation at the controlled end. Perfect interpretation of industrial wireless communication technology products research and development of the original intention and achievement transformation.
