Machine, material is delivered to finished bin or reject bin by it by way of wheel is walked in orbit.Because finished product dolly is being walked
When with certain speed, and its inertia is also larger when load-carrying, so stop position is often not accurate enough.Existing method
Contact-making switch is typically set, and touch contact-making switch after being advanced by finished product dolly stops realizing, but this mode is often
Also it can not realize that accurate position stops, can only be within an error range, and when the load-carrying of finished product dolly is continuous
During change, this error range will be exaggerated, and needed when accurate stop positions and do not applied to for some.
The content of the invention
Therefore, for it is above-mentioned the problem of, the present invention proposes a kind of to realize precisely stopping, the higher pitch of operating efficiency
The small vehicle automatic control method of stirring station finished product.
To achieve the above object, present invention employs following technical scheme：A kind of bituminous mixing plant finished product dolly is controlled automatically
Method processed, comprises the following steps：
The first step, encoder is set in the rotating shaft of finished product dolly, and is arranged at intervals on the track that finished product dolly is advanced
There are a plurality of inductors, pressure sensor is installed on the hopper of finished product dolly, the walking of dolly speed is identified by encoder
Degree, the walking position of dolly is identified by inductor, the weight of dolly is identified by pressure sensor, and will sensing
The signal that device, encoder, pressure sensor obtain is transferred to PLC control system；
Second step, finished product dolly are needed when stopping in a certain finished bin, weight and walking by acquired dolly
Speed calculates the optimal deceleration distance of dolly, and the optimal deceleration distance is the distance between finished bin to a certain inductor, is treated as
When product dolly reaches the inductor, PLC control system obtains signal, a reduction of speed curve is formed, then with pulse signal transmission
To the servomotor of finished product dolly, the stopping of the finished bin is implemented in by the slow reduction of speed of servomotor；
3rd step, when finished product dolly still can pass through a plurality of inductors in down speeding procedure, when reaching any inductor,
The real-time signal that encoder obtains passes to PLC control system, and the signal is compared with reduction of speed curve in pulse signal, from
And draw speed difference, if difference be on the occasion of or negative value, before regenerating a pulse signal by PLC control system to replace it
Pulse signal, if difference be 0, continue to continue to use existing pulse signal；
4th step, sets contact-making switch in finished bin, because the small vehicle speed of finished product now is relatively low, the touching of finished product dolly
After contact-making switch, PLC control system receives contact-making switch signal, and signal is passed into servomotor, and servomotor stops, i.e.,
Realize accurate stop.
Further, brake gear is provided with the finished product dolly, the brake gear is connected with PLC control system,
In step 4, after finished product dolly touches contact-making switch, PLC control system receives contact-making switch signal, and signal is transmitted
To brake gear, brake gear, which starts, realizes brake.
By using preceding solution, the beneficial effects of the invention are as follows：This bituminous mixing plant finished product dolly automatically controls
Method, the speed of travel of dolly is identified by encoder, the walking position of dolly is identified by inductor, is passed by pressure
Sensor identifies the weight of dolly, is then believed by the effect finished product dolly of PLC control system when advancing by pulse
Number slow reduction of speed is realized, and can constantly adjust reduction of speed curve in down speeding procedure and precisely stop when reaching finished bin to realize
Only, contact-making switch is finally set in finished bin, stopping is realized by contacting, prevents that reduction of speed curve is unstable caused by malfunctioning；
Further, by setting brake gear, to realize the collective effect with servomotor, finished product dolly is precisely stopped.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
In conjunction with the drawings and specific embodiments, the present invention is further described.
With reference to figure 1, the present embodiment provides a kind of small vehicle automatic control method of bituminous mixing plant finished product, comprises the following steps：
The first step, encoder is set in the rotating shaft of finished product dolly, and is arranged at intervals on the track that finished product dolly is advanced
There are a plurality of inductors, pressure sensor is installed on the hopper of finished product dolly, the walking of dolly speed is identified by encoder
Degree, the walking position of dolly is identified by inductor, the weight of dolly is identified by pressure sensor, and will sensing
The signal that device, encoder, pressure sensor obtain is transferred to PLC control system；
Second step, finished product dolly are needed when stopping in a certain finished bin, weight and walking by acquired dolly
Speed calculates the optimal deceleration distance of dolly, and the optimal deceleration distance is the distance between finished bin to a certain inductor, is treated as
When product dolly reaches the inductor, PLC control system obtains signal, a reduction of speed curve is formed, then with pulse signal transmission
To the servomotor of finished product dolly, the stopping of the finished bin is implemented in by the slow reduction of speed of servomotor；
3rd step, when finished product dolly still can pass through a plurality of inductors in down speeding procedure, when reaching any inductor,
