3, the SICK obstacle detection device of AGV is in the lower end of headstock, only can detect and highly be the objects in front about 30cm, too high object is existed detect the blind area, and automatic isolating door is in case descend, at first bump against the laser barcode scanning device that is in the top, can't be detected by SICK obstacle detection device.

4, AGV equipment gait of march is slower, and particularly when trans-regional advancing, when headstock part built on stilts surveyed area, automatic isolating door just may descend, and the AGV of this moment does not pass through automatic isolating door yet fully, thereby knocks automatic isolating door.

Therefore, be necessary to design the higher automatism isolation door system of a kind of safety.

The specific embodiment

Below with reference to the drawings and specific embodiments, the utility model is described in further details:

Embodiment 1:

As shown in Figure 1, a kind of automatism isolation door system adaptive with automatic guided vehicle comprises supervisory control comuter, signal picker, wireless base station and the bit detector that rises to that rises and whether put in place for detection of automatic isolating door; Rising to bit detector is connected with the computer interface of supervisory control comuter by signal picker; Supervisory control comuter is connected by Ethernet with the network switch, and the network switch is connected with the wireless base station, and the wireless base station is connected with the automatic guide vehicle radio communication.

What signal picker used is the BIV signal picker of NDC company, that computer interface adopts is MA-21, in order to realize the conversion between 20mA electric current loop agreement and RS232 serial port protocol, the current signal that it can gather signal picker is converted to rs 232 serial interface signal, to facilitate reading of computer.Supervisory control comuter adopts Serial Port Line to be connected with computer interface, receive the signal that transmits and process, supervisory control comuter and the network switch are connected in during industry nets very much jointly, and the information industry Ethernet after processing is passed to the wireless base station, the wireless base station with instruction by being wirelessly transmitted to AGV.

That rise to that bit detector adopts is the photoelectric detector WL100-P1432 of SICK company, rising to bit detector is a kind of reflection type mirror photoelectric detector, employing reflection type mirror photoelectric detector is the interference for fear of other object or light, can only be triggered by the reflector supporting with it.Reflector is arranged on the lower-left end of automatic isolating door, with 1 while of automatic isolating door knee-action, its effect is to support the use with the bit detector body, what the bit detector body was exported at ordinary times is low level, only have when reflector rises to highest order along with automatic isolating door, just in time with rise to relatively with the bit detector body, when the light reflection that the bit detector body is sent went back, the bit detector body was just exported high level.The bit detector body is fixed on the metope of left upper end of automatic isolating door or is arranged on the upper end of automatism isolation doorframe, and reflector only could be detected by the detector body when automatic isolating door rises to highest order.
