Description
Technical field
The utility model relates to a kind of vehicle detection system being applied in automobile production, specifically a kind of vehicle detection system based on producing fail-safe system.
Background technology
In automobile production process, particularly, in assembly shop, the correct detection of vehicle is self-evident for the importance of technique.Tradition vehicle detects, and utilizes optoelectronic switch in specific position, by identification, judges that the structural differences between different automobile types judges.The accurate identification of a vehicle, may need to carry out constantly to correct for a long time, time-consuming effort again.When workshop increases new model, can bring new problem to vehicle identification, thereby need to readjust arranging of optoelectronic switch.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of current traditional detection method, a kind of vehicle detection system based on fail-safe system is provided, it can utilize the control information of upper strata, workshop, by field control system, directly to its upper layer device, asks for current vehicle information data.
According to the technical solution of the utility model, the described vehicle detection system based on fail-safe system, comprise workshop fail-safe system PLC and pipeline field control PLC, described workshop fail-safe system PLC is connected with the computing machine of fail-safe system by network, between workshop fail-safe system PLC and pipeline field control PLC, by 8 core copper cable lines, be connected, pipeline field control PLC connects carrier detector switch and whether one group of detection carrier is empty optoelectronic switch.
Described carrier detector switch is to be arranged on travel switch or the optoelectronic switch that carrier puts in place and locates.
Whether described detection carrier is empty optoelectronic switch when being arranged at carrier and putting in place, answers the both sides of vehicle.
Described pipeline field control PLC is also connected to on-the-spot man-machine interface.
Advantage of the present utility model has:
1. debugging is simple and easy: pipeline field control PLC and workshop fail-safe system PLC number of signals are few, and debugging is convenient;
2. reliability is high: directly by the mistake proofing vehicle queue type information of must picking up the car, and the defect of avoiding switch to detect;
3. favorable expandability: within the specific limits, without increasing again any hardware resource, can realize the expansion of vehicle;
4. on-the-spot controllability is good: by on-the-spot man-machine interface (HMI), can check easily the information that vehicle queue is wrong with change.
Accompanying drawing explanation
Fig. 1 is structural drawing of the present utility model.
Fig. 2 is groundwork process flow diagram of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises: workshop fail-safe system PLC and pipeline field control PLC, workshop fail-safe system PLC is connected with the computing machine of fail-safe system by network, between workshop fail-safe system PLC and pipeline field control PLC, by 8 core copper cable lines, is connected.In normal Workshop Production, because some specific reasons can be moved by free carrier in workshop, now, just need to first unloaded tool be distinguished.Therefore, pipeline field control PLC is connected with carrier detector switch and one group and detects whether carrier is empty optoelectronic switch.Carrier detector switch is to be arranged on travel switch or the optoelectronic switch that carrier puts in place and locates.When detecting carrier and be whether empty optoelectronic switch and being arranged at carrier and putting in place, answer the both sides of vehicle.Pipeline field control PLC carries out exchanges data by the PLC with fail-safe system, utilizes the form of signal connecting line, exchange vehicle information.Whether when carrier triggers after carrier detector switch, by one group of optoelectronic switch, distinguishing carrier is empty, if not empty,, directly to fail-safe system PLC request vehicle information, if carrier is empty, do not ask vehicle information.
The utility model is when work, and fail-safe system PLC asks for vehicle queue to the computing machine of upper fail-safe system, between pipeline field control PLC and fail-safe system PLC, by 8 core copper cable lines, carries out exchanges data.Following table is the example of a simple signal definition.Vehicle information table is shown 42 system forms, can represent altogether 16 kinds of different vehicle information.
| Sequence number | Signal definition |
| 1 | Heartbeat signal |
| 2 | Detect commencing signal |
| 3 | Vehicle information Bit0 |
| 4 | Vehicle information Bit1 |
| 5 | Vehicle information Bit2 |
| 6 | Vehicle information Bit3 |
| 7 | Vehicle feedback signal |
| 8 | Standby |
As shown in Figure 2, carrier triggers after carrier detector switch, and whether first by one group of optoelectronic switch, detecting current carrier is empty.If carrier is empty, is 0000 by vehicle information recording.When carrier is not empty, pipeline field control PLC (PLC 1) sends and detects commencing signal, fail-safe system PLC (PLC 2) reads first information of current queue vehicle, is translated into the binary message pre-defining, and sends to pipeline field control PLC (PLC 1).Pipeline field control PLC (PLC 1) receives vehicle information, and feeds back receipt completion signal, completes a vehicle and reads circulation.
Described pipeline field control PLC is also connected to on-the-spot Human machine interface.The vehicle information that pipeline field control PLC finishes receiving, HMI is upper at the scene directly shows.If there is actual vehicle and queue vehicle when inconsistent, can directly revise inner vehicle queue by HMI.Greatly facilitate the processing of on-the-spot special circumstances, saved the time of changing upper vehicle information.
Visible, the utility model is shared by the scale-of-two vehicle information between two PLC, realizes accurately knowing of vehicle information; By the detector switch of extra installation, to tackle in production system, can not show, but the unloaded tool situation that may occur in actual production.Can, in the situation that Workshop Production queue is definite, fast know accurately current vehicle information and part vehicle queuing message.Without knowing car body feature, can obtain correct vehicle.
