Technical scheme: a kind of automatic stereowarehouse control system; Comprise top layer touch-screen, interlayer PLC controller, bottom control module; Described top layer touch-screen and interlayer PLC controller are through 485 bus communications, and described interlayer PLC controller and bottom control module are through the CAN bus communication; Described bottom control module is the dolly control module; The dolly control module comprises motor drive module, data acquisition module, master control module and CAN EBI, and described motor drive module, data acquisition module and CAN EBI are connected with the master control module respectively.
Wherein, described motor drive module comprises high speed optoelectronic coupling chip and motor drive ic; Described high speed optoelectronic coupling chip is HCPL-2630, and motor drive ic is MC33886; Described main controller module adopts the LPC2119 main control chip, and data acquisition module adopts the LM2576 chip.
The top layer touch-screen is realized the condition monitoring of the assigning of warehouse store tasks order, the monitoring of warehouse stores situation, each components and parts.Interlayer PLC controller links to each other through 485 EBIs with the top layer touch-screen, and interlayer PLC controller is connected through the CAN EBI with the bottom control module.The PLC controller of interlayer decomposes the order of top layer touch-screen to the bottom control module, gives the top layer touch-screen with the message feedback of bottom control module simultaneously.The bottom control module is made up of data trap, master controller, motor driver.The bottom control module can drive the two-way DC machine simultaneously, control such as the bottom control module can start this two-way motor, stops, speed governing.
Beneficial effect: a kind of automatic stereowarehouse control system of the utility model, its advantage has:
(1) the top layer touch-screen in the utility model, interlayer PLC controller, bottom control module adopt the mode of fieldbus to be connected, and the top layer touch-screen is connected through the 2.4G communication with travelling bogie;
(2) because individual memory cells is relatively disperseed, if adopt common control system, system failure rate can be than higher, the expansion of inconvenient system simultaneously, the utility model adopts decentralized control, and each memory cell can independently be controlled;
(3) travelling bogie and top layer touch-screen adopt communication, greatly facilitate wiring and install, and have enlarged the range of movement of dolly.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further.
Extremely shown in Figure 3 like Fig. 1; A kind of automatic stereowarehouse control system of the utility model; Comprise top layer touch-screen, interlayer PLC controller, bottom control module; Top layer touch-screen and interlayer PLC controller are through 485 bus communications, and interlayer PLC controller and bottom control module are through the CAN bus communication; The bottom control module is the dolly control module, and the dolly control module comprises motor drive module, data acquisition module, master control module and CAN EBI, and motor drive module, data acquisition module and CAN EBI are connected with the master control module respectively.
In the present embodiment, motor drive module comprises high speed optoelectronic coupling chip and motor drive ic; High speed optoelectronic coupling chip is HCPL-2630, and motor drive ic is MC33886; Main controller module adopts the LPC2119 main control chip, and data acquisition module adopts the LM2576 chip.
Below specify:
As shown in Figure 1, a kind of automatic stereowarehouse control system of the utility model comprises top layer touch-screen, interlayer PLC controller, bottom control module and motor.The top layer touch-screen is connected through 485 EBIs with the PLC controller of interlayer, is connected with 485 interfaces of PLC through 232 serial ports of 232/485 interface convertor with touch-screen.
As shown in Figure 2, the bottom control module comprises master control module, data acquisition module, motor drive module, CAN EBI.Motor drive module is made up of high speed optoelectronic coupling chip HCPL-2630, motor drive ic MC33886, and the PWM output pin of primary controller and photoelectricity coupling aperture are formed.Wherein master control module selects for use LPC2119 main control chip, data acquisition module to adopt the LM2576 chip that the output voltage of the opto-electronic pickup of two-way 24V is converted into the 5V level that main control chip LPC2119 can import.Motor-driven is linked to each other by the input pin of high speed optoelectronic coupling.The CAN bus interface module is made up of the CAN controller and the CAN bus isolation transceiver CTM-1050 of primary controller.
In the present embodiment, the bottom control module is the travelling bogie control module, and is as shown in Figure 3, and the travelling bogie control module comprises top layer touch-screen, 2.4G wireless communication module, master control module, data acquisition module, motor drive module, motor driver.The top layer touch-screen is connected with the 2.4G wireless communication module; The master control module is connected with data acquisition module, motor drive module, motor driver and 2.4G wireless communication module respectively, and motor drive module and motor driver drive go motor and door motor respectively.2.4G wireless communication module comprises sending module and receiver module, the top layer touch-screen is connected with the 2.4G wireless sending module through the RS232 serial ports, and the ultimate range of transmission over radio can reach 300 meters.
