It is not connected to local module, local module connects master controller by fieldbus；Height sensor connects remote analog amount mould
Block, remote analog amount module connect master controller by fieldbus；
The spot sensor is used for the mobile contraposition of vehicle body and chassis；
In body bottom, at least one measurement point is set；On Lifting bench upper table surface immediately below the measurement point setting with
The one-to-one height sensor of measurement point.
More preferably, former and later two measurement points are set in body bottom, correspondingly, setting and measurement point on Lifting bench upper table surface
One-to-one two height sensors.
Further, the spot sensor includes：
Vehicle body lifting appliance occupy-place/deceleration/the sensors in place being arranged on suspender track；

The Lifting bench up/down being arranged on Lifting bench in place, up/down slow down, up/down limit sensors.
Further, the height sensor uses laser range sensor.
The advantage of the invention is that：
1）Sensor is concentrated, and PLC is all connected to, quick and easy for installation.
2）Laser range sensor Real-time Feedback height value, PLC judge more accurate compared to manually.
Description of the drawings
Fig. 1 is that the body of a motor car chassis of the present invention attaches together production line schematic diagram.
Fig. 2 is the control system electricity functional block diagram of the present invention.
Specific implementation mode
With reference to specific drawings and examples, the invention will be further described.
A kind of body of a motor car chassis newly come into operation attaches together production line at present, as shown in Figure 1, including：
Lifting bench 1, rolling bed 2, vehicle body lifting appliance 3, suspender track 4；Vehicle body 5 is lifted by vehicle body lifting appliance 3 and is moved along suspender track 4
To 1 top of Lifting bench, chassis 6 is delivered to 1 top of Lifting bench by rolling bed 2, and then Lifting bench 1 acts, upward jacking chassis 6,
So that chassis 6 is attached together with the contraposition of vehicle body 5.
Vehicle body lifting appliance occupy-place/deceleration/sensors in place is equipped on suspender track 4, for so that lifting vehicle body position essence
Really in place；Chassis occupy-place/deceleration/sensors in place is equipped in rolling bed 2, in place for the movement conveying of chassis 6；In Lifting bench 1
On be additionally provided with Lifting bench up/down in place, up/down slow down, up/down limit sensors；Above-mentioned spot sensor can make vehicle body 5
Contraposition can be moved with chassis 6.
It is attached together on production line in same chassis, it is often necessary to which carry out different automobile types attaches together production, artificial to estimate
Whether vehicle body and chassis attach together successfully control relative difficult.
For this purpose, at least one measurement point 7 is arranged in 5 bottom of vehicle body；Lifting bench 1 immediately below the measurement point 7 is appeared on the stage
Setting and 7 one-to-one height sensor 8 of measurement point on face；More preferably, former and later two measurement points 7 are set in 5 bottom of vehicle body,
Correspondingly, setting and 7 one-to-one two height sensors 8 of measurement point on 1 upper table surface of Lifting bench.8 this example of height sensor
It is middle to use laser range sensor.
Multi-vehicle-type Flexible production chassis attaches together the electric principle of automatic control system as shown in Fig. 2, including main control
Device, fieldbus, far module, spot sensor（Vehicle body lifting appliance occupy-place/deceleration/sensors in place, chassis occupy-place/deceleration/are arrived
Level sensor, Lifting bench up/down in place, up/down slow down, up/down limit sensors）, local module, frequency converter, Lifting bench electricity
Machine, vehicle body lifting appliance mobile motor, remote analog amount module, height sensor 8；Wherein master controller uses PLC（Field-programmable
Module）.
Master controller passes through network connection host computer；Spot sensor is connected to far module, and far module passes through scene
Bus connects master controller；Lifting bench motor and vehicle body lifting appliance mobile motor are connected to frequency converter, the input and output point of frequency converter
It is not connected to local module, local module connects master controller by fieldbus；Height sensor 8 connects remote analog amount mould
Block, remote analog amount module connect master controller by fieldbus.
The operation principle of the present invention is to be arranged and preserve the model data for needing to attach together in host computer.To each vehicle, so
Gross data confirmation early period is carried out afterwards, is simulated in automobile graphics and is attached together successfully each measurement point of rear and height sensor 8
Difference in height, to select the range and precision of laser range sensor.
After laser range sensor installation, special messenger is arranged to count the difference in height of body station and height sensor, with
Each vehicle altitude information is several（Such as former and later two height values in this example）, each vehicle is finally determined according to altitude information
Attach together successful theoretical level value.
After vehicle body and chassis attach together, height sensor 8（Laser range sensor）By the height to measurement point of actual acquisition
Angle value is by remote analog amount module feedback to master controller（PLC）, master controller learns the vehicle currently attached together from host computer,
Successful theoretical level value is attached together according to each vehicle to be compared with the analog quantity value of feedback with laser range sensor, is exceeded
Range then sends out sound-light alarm, then by the vehicle body after attaching together and chassis automatic transporting to next station in normal range (NR).
