Scram control circuit, control method, and pumper

Abstract

The invention provides a scram control circuit, and a scram way comprises a remote control scram and a close control scram. The scram control circuit comprises a power supply; a receiver, which is used to receive remote control scram signals transmitted by a transmitter of a remote controller; a close control scram trigger element, which is used for receiving close control scram trigger signals; a selective switch, which is used to select the scram ways after receiving operation instructions; a changing switch, which is used to control the power supply state of the power supply used as the receiver according to the scram way selected by the selective switch, and is used to switch the transmission lines of the remote control scram signals and the close control scram trigger signals according to the scram way; and a controller, which is used for the scram control according to the remote control scram signals or the close-control scram trigger signals. The scram control circuit is advantageous in that the occupied input ends of the controller are less, the later function extension can be facilitated, the electric energy waste of the receiver of the remote controller can be reduced, and the scram signals can be easily controlled in an integrated manner. The invention also provides a pumper having the control circuit, and a scram control method.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an emergency stop control circuit, a pump truck with the same, and an emergency stop control method. Background technique [0002] A pump truck is a machine used to transport materials. When the pump truck encounters an emergency, it can be stopped by the emergency stop control. Among them, the emergency stop signal of the electronic control system of the pump truck equipped with a remote control includes two types: close-controlled emergency stop and remote control emergency stop. Remote control emergency stop refers to the emergency stop operation when the equipment is operated by the remote control, and close control emergency stop refers to the emergency stop operation when the equipment is operated by close control. figure 1 It is a schematic diagram of an emergency stop control circuit in the prior art. Select remote emergency stop or near-control emergency stop through ...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that in the related art, there are three emergency stop input terminals, which occupy more input control point resources of the controller 10', which is not conducive to the expansion of complex functions in the later stage; when the controller 10' receives the emergency stop signal, it needs to judge which One input end is abnormal, and then the remote control or close control emergency stop control is performed; after the electric control system of the pump truck is powered on, regardless of the close control emergency stop or the remote control emergency stop, the receiver 20' of the remote control is always in the power supply state, thus causing electric energy Waste, the receiver 20' being in the state for a long time has a great impact on the life of electrical components; the parallel operation of three emergency stop signals is not conducive to integrated control
