Problems solved by technology

If it is a double-compartment or multi-compartment transport vehicle, the unloading process is more complicated. During the process of unloading the remaining material, it is necessary to watch the pressure gauge and continuously close / open different valves to unload the remaining material one by one. The operation process is complicated and takes a long time. , high labor intensity and poor safety

Abstract

The present invention discloses an intelligent discharge control method for powder material dump truck. It utilizes microprocessor to execute stored control program and automatically detect the pressure of material storage tank and control discharge valve so as to implement intelligent control of discharge process. The equipment for implementing said intelligent discharge control includes microcontroller, 24V vehicle power supply, PWM-type DC / DC converter, pressure sensor, amplifier, filter, A / D converter, discharge valve, detection circuit, air compressor and microprocessor, etc. Its control program uses assembler language or C language.

Description

Technical field [0001] The invention relates to an intelligent unloading control method for a powder material transport vehicle. The method can be mainly applied to the design of the automatic control system of the unloading process of the powder material transport vehicle such as cement, mineral powder, various powdered chemical raw materials, etc. Background technique [0002] In daily transportation activities, the transportation of powdered materials is often encountered, such as the transportation of cement, mineral powder, and other powdered chemical raw materials. Take the transportation of cement as an example. When the cement reaches the destination, the cement (powdered) in the truck needs to be unloaded and loaded into the cement storage tank on the construction site. The unloading process is generally: start the air compressor, wait for the pressure to rise to the specified value, manually open the unloading valve, under the action of compressed air, the powdery cemen...
