The utility model discloses a simulation traffic signal lamp mechanism realizes AGV traffic management, the full automatic control of entire system, and manpower resources have significantly reduced, system principle and simple structure, follow -up maintenance is convenient.
Description
Technical field
The utility model relates to automatical pilot transportation vehicle field of traffic control, particularly relates to a kind of AGV traffic signals management system.
Background technology
More existing AGV dolly head installs laser obstacle scanning sensor, when two dollies can cause two AGV dollies to be all in emergency stop conditions when meeting in intersection, now must by manually carrying out control AGV dolly, automaticity is low, needs manual intervention.When many AGV dollies run simultaneously, travel on highway like automobile, need equipment as similar traffic lights to manage the Methodistic operation of AGV dolly.Most of AGV dolly passes through to increase wireless module on AGV dolly on the market at present, carry out radio communication by host computer and AGV dolly, reach the object of intervening AGV dolly, but wireless signal anti-interference is poor, there is higher potential safety hazard, the cost of installation and maintenance is simultaneously higher; The barrier scanning sensor that AGV dolly is equipped with in addition can only detect linearity region, front or sector region, so just certainly exist sensor " visual field " blind area, within both sides come in and go out the other side " visual field " blind area when two AGV dollies meet at the parting of the ways, easily cause car to car impact.
Utility model content
The purpose of this utility model is the defect overcoming prior art existence, the AGV traffic signals management system providing a kind of Automatic Control, cost low, safe and reliable.
The technical scheme realizing the utility model object is: AGV traffic signals management system, comprises above ground portion and AGV part, and above ground portion comprises the first Optical Communication Terminal and single-chip microcomputer that are arranged on each right-angled intersection, and the first Optical Communication Terminal is connected with single-chip microcomputer; AGV part comprises AGV dolly, is arranged on AGV dolly head, the second Optical Communication Terminal of afterbody and PLC, and the second Optical Communication Terminal is connected with PLC.
As prioritization scheme of the present utility model, install 4 the first Optical Communication Terminals at each right-angled intersection, 4 the first Optical Communication Terminals are arranged at four orientation of right-angled intersection respectively.
The utility model has positive effect: 1) realize AGV traffic administration by simulation traffic lights mechanism, whole system Automatic Control, greatly reduces human resources;
2) simply, follow-up maintenance is convenient for system principle and structure;
3) system cost is low, without the need to the support of a large amount of hardware device;
4) system uses Optical Communication Terminal to realize accurate control, safety and stability, reliable, and operating voltage is low.
Accompanying drawing explanation
Fig. 1 is the process flow diagram of the utility model method;
Fig. 2 is enforcement illustration of the present utility model.
Embodiment
The utility model discloses AGV traffic signals management system, comprise above ground portion and AGV part, above ground portion comprises the first Optical Communication Terminal and single-chip microcomputer that are arranged on each right-angled intersection, and the first Optical Communication Terminal is connected with single-chip microcomputer; AGV part comprises AGV dolly, is arranged on AGV dolly head, the second Optical Communication Terminal of afterbody and PLC, and the second Optical Communication Terminal is connected with PLC.
Install 4 the first Optical Communication Terminals at each right-angled intersection, 4 the first Optical Communication Terminals are arranged at four orientation of right-angled intersection respectively.
As shown in Figure 1, the management method of AGV traffic signals management system, the method comprises the following steps:
1) before right-angled intersection, AGV dolly sends by request by the second Optical Communication Terminal;
2) single-chip microcomputer is when receiving by request, and then the AGV dolly detecting current right-angled intersection arranges traffic behavior for obstruction or unimpeded by situation, and AGV dolly is sent to PLC by the information of situation by the first Optical Communication Terminal by single-chip microcomputer;
3) PLC control AGV dolly performs by right-angled intersection or the action waited for before right-angled intersection;
4) AGV dolly afterbody is by after right-angled intersection, can send AGV dolly by signal to single-chip microcomputer, traffic behavior is set to unimpeded state by single-chip microcomputer.
Single-chip microcomputer receives the data by request that AGV dolly is sent by the second Optical Communication Terminal, whether now single-chip microcomputer can detect current right-angled intersection has AGV dolly to pass through, if now there is AGV dolly to pass through, single-chip microcomputer can send waiting signal by the first Optical Communication Terminal to AGV dolly, if now do not have AGV dolly to pass through, single-chip microcomputer then can send and allow right of way signal and arrange now traffic behavior to pass through for there being AGV dolly.Until AGV dolly by telling during crossing that Chip Microcomputer A GV dolly passes through, now single-chip microcomputer arranges traffic behavior is unimpeded state.
AGV dolly head and afterbody all the second Optical Communication Terminal can be installed, AGV carriage walking sends request to the second optical communication chance of head during right-angled intersection and passes through signal, allow be walked on by signal AGV dolly once receive, send AGV dolly until AGV dolly by the second optical communication chance of afterbody during right-angled intersection and pass through signal.Otherwise AGV dolly can be waited at crossing until receive and allow to pass through signal always.
As shown in Figure 2,4 first Optical Communication Terminals A, B, C and D are divided into two groups, and A, C are one group, and B, D are one group, and arrow represents the direction that AGV dolly travels.When AGV dolly is through the first Optical Communication Terminal A, AGV dolly can stop and to communicate with A, AGV dolly sends and passes through request signal, if now single-chip microcomputer judges whether another road has AGV dolly travelling AGV dolly in traveling, single-chip microcomputer sends to AGV dolly waiting signal by A, if do not have AGV dolly current by right-angled intersection, single-chip microcomputer to be sent to AGV dolly by A and allows to pass through signal.When AGV dolly receives permission by signal, AGV dolly continues to move ahead, until AGV dolly afterbody is by the first Optical Communication Terminal C, AGV dolly stops to C transmission AGV dolly and passes through signal.If in the meantime D, B place road have the request of AGV dolly by; be parked in original place and wait for, only receive AGV dolly on A, C road to single-chip microcomputer and send and pass through signal.PLC receives the data that single-chip microcomputer sends over, PLC resolution data, when parsing current demand signal and being waiting signal, PLC sends stop signal to AGV dolly, when parsing signal for allowing by signal, PLC sends to AGV dolly passes through signal.Be positioned at the second Optical Communication Terminal of AGV dolly head and afterbody, when guaranteeing to sail into, headstock can not enter crossing, and when rolling away from, the tailstock leaves crossing.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
