Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described in detail; the embodiment of accompanying drawing is not a limitation of the present invention; every according to the present invention with embodiment improvement or the similar techniques scheme done, all belong to the claimed technical scope of the present invention.
The accompanying drawing 1 expression goods of the present invention control block diagram of full automaticity vertical transit system, be system of the present invention control principle signal, comprise remote controller receiving terminal, frequency-changing elevator controller, change over controller PLC, vertical gate machine controller, load transfer device controller PLC, accompanying drawing 3 is depicted as system works flow process figure, in conjunction with the accompanying drawings 1 and accompanying drawing 3, the principle of work of technical solution of the present invention specifically is described below:
When the as ready district has goods to transport, the beeper uses dedicated remote control to send calling signal and purpose floor signal, behind the calling signal and purpose floor signal that remote controller receiving terminal reception dedicated remote control sends, the remote controller receiving terminal sends to the frequency-changing elevator controller with calling signal, and the purpose floor signal is sent change over controller PLC; The frequency-changing elevator controller sends the startup energizing signal to the load transfer device controller PLC after receiving calling signal simultaneously, and change over controller PLC sends the entry condition signal to the load transfer device controller PLC after receiving the purpose floor signal; Frequency-changing elevator controller response calling signal need carry out logic determines from three aspects: treat the scalariform attitude calling signal that then makes an immediate response if elevator is in, frequency-changing elevator controller control elevator moves to exhales terraced floor, send enabling signal to the vertical gate machine controller, the vertical gate machine controller is opened hoistway door; If elevator is being carried out other transportation burden, then to treat to respond calling signal in order after other task is finished, frequency-changing elevator controller control elevator moves to exhales terraced floor, sends enabling signal to the vertical gate machine controller, and the vertical gate machine controller is opened hoistway door; If elevator is being carried out the order that conveys goods to exhaling terraced floor, after the system that then treats was transported to the loading dock with goods, the frequency-changing elevator controller responded calling signal again, and keep hoistway door to open this moment.When the vertical gate machine controller was opened hoistway door or kept hoistway door to open, the vertical gate machine controller sent acknowledgment signal to the load transfer device controller PLC.After change over controller PLC receives the purpose floor signal, change over controller PLC distributes corresponding purpose floor signal to give the frequency-changing elevator controller by the calling signal that elevator responded, make elevator when conveying goods, remain the sole purpose floor signal, avoid elevator to transport the floor mistake owing to signal holds the surplus goods that makes.After the load transfer device controller PLC is received the affirmation signal that entry condition signal that change over controller PLC sends, startup energizing signal that the frequency-changing elevator controller sends and vertical gate machine controller send, load transfer device controller PLC output control signal is given the actuating device of self, the motor that drives horizontal feed equipment is realized converting operation, reaches the purpose with the transportation of goods automatic horizontal.The load transfer device controller PLC is sent the responsive feedback signal to change over controller PLC when driving horizontal feed equipment delivery goods, change over controller PLC sends purpose floor control signal to the frequency-changing elevator controller after receiving the responsive feedback signal.Equally, when horizontal feed equipment brings into operation, the load transfer device controller PLC is also sent the work feedback signal to the frequency-changing elevator controller, and the horizontal transportation burden of apprizing system carries out, and elevator keeps door opening state; Finish when outside load transfer device transports, be about to goods and be transported on the delivered inside equipment, the load transfer device controller PLC is sent the work feedback signal to the frequency-changing elevator controller, informs that horizontal transportation burden finishes, and elevator door cuts out, and starts the vertical transport task.The frequency-changing elevator controller moves to the purpose floor according to the purpose floor signal control elevator that change over controller PLC distributes, and sends enabling signal to the vertical gate machine controller.The vertical gate machine controller drives hoistway door and opens, and sends acknowledgment signal to the load transfer device controller PLC simultaneously.When the load transfer device controller PLC receives the confirmation signal, the load transfer device controller PLC need be carried out logic determines: if there is not goods to be unloaded on the outside load transfer device, the direct response confirmation signal of load transfer device controller PLC then, the load transfer device loading dock that conveys goods is unloaded internally; If lead on the outside load transfer device of loading dock goods arranged, the load transfer device controller PLC is sent the work feedback signal to the frequency-changing elevator controller, elevator door keeps often opening, and give the alarm, after the goods on the outside load transfer device is removed, the load transfer device controller PLC is the response confirmation signal, conveys goods to the loading dock on the load transfer device internally.After goods is transported to the loading dock and unloads, horizontal feed equipment stops transportation, whether the load transfer device controller PLC detects the as ready district goods to be carried, if goods to be carried is arranged, the load transfer device controller PLC is sent the work feedback signal to the frequency-changing elevator controller, hoistway door keeps normally open, and horizontal feed equipment conveys goods in elevator; If the as ready district does not have goods to be carried, the load transfer device controller PLC is sent the work feedback signal to the frequency-changing elevator controller, hoistway door is closed, and system finishes full automaticity goods transport flow process one time, and elevator enters to be treated the scalariform attitude or respond other calling signal in order.
Accompanying drawing 2 is the pinouts of change over controller PLC among Fig. 1; 2 effects of explanation change over controller PLC in system control device with reference to the accompanying drawings below, in the specific embodiment of the present invention, change over controller adopts small PLC, X1~X7 is the authority address signal input end of remote controller, X11~X17 is a purpose floor signal input end, and X21~X27 is the responsive feedback signal input part, and Y1~Y7 is a purpose floor control signal output ends, X0 is the detection signal input end of panel block in the sedan-chair, and Y0 is the power control signal mouth.Suppose the input of detection signal input end X0 no signal, the beeper uses dedicated remote control to exhale ladder in the 3rd buildings, send calling signal, sends the purpose floor signal simultaneously, and having registered the purpose floor is the 5th buildings; The remote controller receiving terminal sends to purpose floor signal the 5th buildings the purpose floor signal input end X15 of change over controller PLC, change over controller PLC judges that by authority address signal input end X3 this purpose floor signal is the purpose floor signal that the 3rd buildings send, the storage of after the change over controller PLC received signal purpose floor signal the 5th buildings being ranked, calling signal when frequency-changing elevator controller ordinal response the 3rd buildings, the responsive feedback signal input part X25 of change over controller PLC exports purpose floor control signal (the 5th building) to the frequency-changing elevator controller from purpose floor control signal output ends Y5 after receiving the responsive feedback signal that the load transfer device controller PLC is sent outside three balconies, removes storage simultaneously; Move afterwards by elevator and load transfer device and finish, after goods is delivered in the car, send the straight signal for the frequency-changing elevator controller, guarantee that elevator does not respond other calling signal when conveying goods by the load transfer device controller PLC, this is the elevator current techique, does not do superfluous chatting.Above-mentioned working process is the full automaticity transportation that realizes under the situation unmanned in car, and promptly the button of panel block does not have manual incoming signal in the sedan-chair.But exist the people and goods to take the situation of an elevator simultaneously sometimes, at this time need the assurance personnel to transport preferential and personal safety.Concrete technical scheme is: the panel block detection signal has precedence over other remote signals in the sedan-chair, the detection signal input end X0 of change over controller PLC detects whether panel block has instructs registration in the sedan-chair, if the detection signal input end X0 of change over controller PLC detects panel block detection signal in the sedan-chair, show that the interior passenger of sedan-chair supresses the button of panel block in the sedan-chair, the power control signal mouth YO out-put supply control signal of change over controller PLC then, cut off the power supply of load transfer device and remote controller receiving terminal, make elevator independent operating in self control system, no longer respond any signal of dedicated remote control and load transfer device controller PLC, to guarantee the running priority of people in the sedan-chair, there is the people to enter elevator independence purpose of safe operation in the elevator in case reach.
Frequency-changing elevator controller control elevator among the present invention vertically moves, and load transfer device controller PLC driving horizontal feed equipment carries out goods and transports, and the present invention does not repeat them here.
