In the present embodiment, control system 8 comprises control apparatus and control software design, and control apparatus and electromagnetic valve integrated box 20 are connected by signal wire (SW) and realize air operated control, to be connected through signal wire (SW) with the actuator of servomotor 12 realize driving, locate, braking controls; Wherein: control apparatus comprises industrial computer, relay, voltage transformer, coder, actuator and level indicator, industrial computer is connected with relay by Serial Port Line, relay is connected with level indicator, coder and actuator respectively by data line, and voltage transformer is connected with industrial computer by COM serial port; Control software design comprises Pneumatic control module, control module for servo motor, locating module, brake module and upper computer control module; Control module for servo motor comprises rate control module and position control module; Car body 1 is the supporting body of all the other various parts, and surrounding is provided with position transduser.The work of control system 8 accessory drive realizes car load and travels, and the work of control jacking system realizes car body 1 and supporting plate 2 is elevated.

Shuttle running rail layer is divided into horizontal and vertical track.During use, be placed on cross track by intelligent four-way shuttle, four cylinder pistons 19 in jacking system rise jack-up supporting plate 2, and pallet is separated with shelf.Now be road wheel with four wheels 13 of guide rail contact, all the other four wheels 13 are unsettled, corresponding actuating device work, drive shuttle to advance.When shuttle arrive in length and breadth track intersection time, four wheels 13 not contacting track, under all the other four cylinder pistons 19 push up the effect of power, to decline certain altitude, make the wheel 13 that contacted unsettled.Because four wheel 13 direction of travel of different directions are orthogonal, now, the just wheel 13 of contact track, its corresponding actuating device work, band motor car wheel 13 rotates, and the direction of travel of shuttle the change of an angle of 90 degrees will occur.When behind arrival destination, cylinder piston 19 declines and drives supporting plate 2 to decline, and goods on supporting plate 2 is contacted with supporting body (as shelf), by goods unloading, and then controls shuttle and exits, achieve the carrying action of goods.

Shuttle provided by the invention can not only do four-way travel operation on straight track, can also travel on the track with certain slope.Each action details of shuttle is monitored by industrial computer and controls, and has full automaticity, S. A. two kinds of mode of operations.

As shown in Figure 5, each is shuttle independently, and car is loaded with a set of control system all separately.This cover control system can realize automation leveling supporting plate, the account of the history that record shuttle runs.By using the Web communication technology, various control command being sent to each shuttle, thus achieves the Long-distance Control to shuttle.Client can inquire about the running condition of the current or history of shuttle, the convenient tracking to shuttle and management.The record of shuttle history run situation is recorded by the vehicle-mounted data storehouse of on program industrial computer.When shuttle runs, when electric current and voltage and other parameters are read in timing, and other parameters etc. of being correlated with of power consumption that the parameter value calculation that can measure according to these uses.By the Web communication technology, can easily in the account of the history of client query to appointment shuttle.

As shown in Figure 6, can carry out to each shuttle the spotlight that Long-distance Control is this shuttle in client.Each shuttle is all furnished with the IP of each self-retaining, by the Web communication technology, can to the shuttle transmit operation instruction of assigned ip, and shuttle just can perform corresponding action after receiving operating order.Like this, network technology is utilized just can to realize the Long-distance Control to shuttle.Owing to not using remote controller one to one, it also avoid the situation that the shuttle that causes because of this operation error of remote controller with other shuttles wrong is out of control.

This shuttle provides electricity by battery pack 9, battery pack 9 is undertaken charging and controlling by intelligent transformer, voltage transformer is connected with industrial computer by COM serial port, can realize alternately to the setting of output voltage electric current and other parameters with to other the real-time monitoring of parameter such as voltage, electric current and charge volume then by industrial computer and voltage transformer, and can by checking to historic records the electric quantity consumption etc. understanding certain period.By the power supply of battery pack 9 can allow shuttle stable be operated in the environment of low-voltage safety under.

Staff is by sending to the industrial computer of control system 8 running that instruction controls servomotor as shown in Figure 7, is then driven the motion of shuttle by servomotor.Servomotor can be controlled with the running of different mode of operations, reach the object accurately controlling shuttle operational factor.Servomotor 12 mode of operation comprises speed control mode and position control mode.Speed control mode can allow shuttle remain in a constant speed and run, and to reach the effect of fast and stable, and position control mode can calibrate the position of shuttle, is used for realizing accurate positioning work.

Concrete operations flow process is:

Control apparatus can allow shuttle stop on the slope, enhances the adding of this device the braking function of servomotor 12 itself, more ensure that shuttle can stopping promptly and accurately.

Level indicator is used for monitoring the balance of supporting plate 2, can be arranged the balance of balance parameters and accurate monitoring supporting plate 2 by industrial computer.Coordinate the jacking function of cylinder to carry out leveling shuttle supporting plate 2 to be horizontal all the time, with ensure shuttle run stop, upward slope descending time supporting plate 2 balance, ensure that goods can not topple and collapse.The realization of supporting plate leveling automation, be measure current angular by supporting plate being placed level indicator, industrial computer reads current angular slope value by level indicator.When angle exceedes default leveling angular range, cylinder is started working, and rises or decline according to actual conditions, until leaning angle is less than the angle that default leveling stops, thus the angle of inclination controlling supporting plate is less than certain scope all the time, as shown in Figure 8.

The realization of cylinder jacking is the solenoid control by 3 position-5 way, and the switch of electromagnetic valve is controlled by intelligent relay, by using the cooperation of two relay switches can realize cylinder ascending, descending and hold mode function, relay also can be controlled by industrial computer.

Above-mentioned is can understand and apply the invention for ease of those skilled in the art to the description of embodiment.Person skilled in the art obviously easily can make various amendment to these embodiments, and General Principle described herein is applied in other embodiments and need not through performing creative labour.Therefore, the invention is not restricted to embodiment here, those skilled in the art, according to announcement of the present invention, do not depart from improvement that scope makes and amendment all should within protection scope of the present invention.
