Background technique
With subway in each big city with more and more extensive, the market demand of subway line corollary equipment is also increasingly
Greatly, function is also more comprehensive.Subway power grid and track detecting due to its special operation mode, need operating condition detection vehicle with compared with
Low speed travels at the uniform speed, if speed not easy to control and fatiguability will occur by driver's long-duration driving always.
Under this extraordinary operating condition, the traction locomotive for developing a kind of carrying automated driving system is to solve to drive difficult good method.
Subway shunter vehicle does not have low constant speed function mostly at present, and small part is shunt with low constant speed function due to it
The characteristics of control strategy, causes control speed unstable, is not able to satisfy user demand.Shunter low constant speed control is general at present
Need to install independent autopilot facility, with high costs and control is unstable.
Summary of the invention
To solve the above-mentioned problems, the present invention proposes a kind of low constant speed intelligence control system of locomotive, specifically, including：
For acquiring and controlling the locomotive microcomputer of locomotive speed, the locomotive wheel that runs and turn on rail for guaranteeing locomotive
Right and diesel engine, the output end of the input terminal connection locomotive microcomputer of the diesel engine, the output end of the diesel engine connect machine
Wheel pair further includes：For the flow control proportioning valve to train wheel air damping, and for detecting turning for locomotive speed
Fast sensor；The output end of the input terminal electrical connection locomotive microcomputer of the flow control proportioning valve, the flow control proportioning valve
Output end connect train wheel；The speed probe is set in the shaft of train wheel, the speed probe it is defeated
The input terminal of outlet electrical connection locomotive microcomputer.
According to the low constant speed intelligence control system of above-mentioned locomotive, the present invention also proposes a kind of low constant speed intelligent control side of locomotive
Method includes the following steps：
S1. whether locomotive speed is less than given value, if so, executing step S3；Otherwise, step S2 is executed；
S2. whether locomotive speed is greater than given value, if so, executing step S4；Otherwise, step S5 is executed；
S3. locomotive microcomputer promotes diesel engine speed, accelerates locomotive, and locomotive speed is made to be increased to given value；
S4. locomotive microcomputer reduces diesel engine speed, and the logical flow control proportioning valve that adjusts takes air damping to train wheel, with
Locomotive speed is set to be reduced to given value；
S5. keep locomotive with constant-speed operation.
Further, the given value of the locomotive speed is any one in 3km/h, 5km/h and 8km/h.
The beneficial effects of the present invention are：
（1）The present invention uses locomotive microcomputer as control unit, save the cost, and passes through adjusting diesel engine speed and flow control
Proportioning valve realizes control, and system structure is simple.
（2）The present invention can conveniently realize the low perseverance of locomotive independent of accurate mathematical model using intelligent control method
Speed control, system stability are good.
Detailed description of the invention
Fig. 1 is a kind of flow chart of the low constant speed intelligent control method of locomotive；
Fig. 2 is a kind of schematic diagram of the low constant speed intelligence control system of locomotive.
Specific embodiment
For a clearer understanding of the technical characteristics, objects and effects of the present invention, this hair of Detailed description of the invention is now compareed
Bright specific embodiment.
The present invention proposes a kind of low constant speed intelligence control system of locomotive and method, as shown in Fig. 2, this control system includes：
For acquiring and controlling the locomotive microcomputer of locomotive speed, the train wheel for running and turning on rail for guaranteeing locomotive, with
And diesel engine, the output end of the input terminal connection locomotive microcomputer of the diesel engine, the output end of the diesel engine connect locomotive wheel
It is right, further include：Revolving speed for the flow control proportioning valve to train wheel air damping, and for detecting locomotive speed passes
Sensor.The flow control proportioning valve input terminal electrical connection locomotive microcomputer output end, the flow control proportioning valve it is defeated
Outlet connects train wheel.The speed probe is set in the shaft of train wheel, the output end of the speed probe
It is electrically connected the input terminal of locomotive microcomputer.
As shown in Figure 1, this control method by control diesel engine speed and air damping come realize 3km/h, 5km/h,
8km/h third gear constant speed function.When locomotive speed is less than given value, locomotive microcomputer rises diesel engine speed automatically, accelerates locomotive；
When locomotive speed is greater than given value, the method that integrated use reduces diesel engine speed and air damping drops to locomotive speed
Given value, to realize locomotive constant speed function.
In an embodiment of the present invention, locomotive microcomputer acquires the operating parameter of locomotive in real time, and carries out analysis and Control, according to
The deviation of setting speed and actual speed implements control strategy.Implement to control by velocity contrast, locomotive can be made in control process
Speed, which is deteriorated, shakes decaying, gradually approaches target velocity.
