Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is further described.

by shown in Figure 1, a kind of Regular loading truck control system of the utility model, described Regular loading truck control system is by the high-performance low-power-consumption processor, the TFT LCD MODULE, the IIC memory module, the CAN bus, host computer, the pump valve switch, power unit, card reader, keyboard, overflow static module, real-time clock, temperature sensing module and flowmeter form, wherein the high-performance low-power-consumption processor is connecting the TFT LCD MODULE, the IIC memory module, the CAN bus, host computer, the pump valve switch, power unit, card reader, keyboard, overflow static module, real-time clock, temperature sensing module and flowmeter.

Described pump valve switch connects and is controlling in-line pump and electro hydraulic valve door by signal.Described card reader is connecting host computer by signal.

The high-performance low-power-consumption processor, for processing and control module, mainly gathers the information of modules, then the information that gathers is processed, and completes the algorithm computing, makes the normal orderly work of modules.The TFT LCD MODULE is mainly the state that shows work at present, and processor is presented in concrete duty in face of people intuitively according to different situations.IIC memory module essential record function, controller carry out the fluid quantitative entrucking the time whole entrucking information all store in the IIC memory module convenient after inquiry.The CAN bus is used for controller and other device talks use bus interface to facilitate system extension.Host computer is patterned operation interface, can realize the Long-distance Control of fluid quantitative entrucking, host computer sends instructions to controller, controller is completed the entrucking process according to the indication of host computer, controller is completed entrucking afterwards the entrucking signal return, and host computer is stored entrucking information by database.The pump valve switch is mainly the Kai Heguan that controls in-line pump and electro hydraulic valve.Power supply is the whole system power supply, after power supply output, power supply is processed, and the Limited Current size, power to different modules, and card reader is mainly for card-punching system, reads host computer and writes the information of card, then according to card image, carries out work.Keyboard is mainly for the setting of system and operation.Overflow static module is the safeguard protection signal in the entrucking process.The overflow static module system of breaking down will lockedly stop entrucking.Real-time clock is used to system that correct time is provided.The temperature sensing module is that the impact of temperature convection body is very large for the compensation of fluid, and the volume that the different temperatures fluid is corresponding is also not identical.Flowmeter mainly is applicable to the flow of test fluid, according to the difference of flow, transmits a signal to controller.Controller technology fluid flow and entrucking information.

In concrete use procedure, the main control processing section is mainly the driving circuit of TFT LCD MODULE, communication interface with pc RS485/CAN bus interface, the interface of keyboard, processor detect the input of keyboard and then according to input, whole system are controlled and operated.Above integrated card reader module, real-time clock, EEPOM adopt the CAN bus to be hooked together, and system data is write EEPOM, are used for inquiry and the setting of system.The power pack of whole system, export the 12V digital power by power unit, 5V digital power, 3.3V digital power, 3.3V analog power, 1.8V digital power after the input of 24V power supply., for the different part of system provides different working powers, be used for 485 interfaces of upper machine communication, the CAN bus interface.Detect the signal of overflow static module, the signal of overflow static module adopts the variation of passive contact point signal detection signal, be used for the detection of flowmeter, detect the signal of flowmeter 0-10KHZ and then give the processor processing, processor shows after processing on the TFT LCD MODULE.Be used for the detection of temperature, detected temperatures meter signal 4-20MA, hand over a processor to process the information that detects, and processor compensates according to temperature value convection cell volume.
