Abstract
The utility model provides a simple high-accuracy position system, comprising a programmable controller, an operating screen, an encoder, a frequency converter, and a mechanical drive executive device. The mechanical drive executive device comprises a motor, a speed reducer, and a dolly. The programmable controller and the operating screen are connected, and the programmable controller controls the frequency converter through a circuit. The frequency converter is connected with the motor. The motor is connected with the speed reducer. The speed reducer controls operation of the dolly. The encoder follows movement of the dolly and acquires signals in real time to feed back the signals to the programmable controller. The programmable controller performs calculation combining preset parameters of the operating screen, and output results to the frequency converter, thereby controlling the motor and the speed reducer to drag the dolly to operate. Beneficial effects of the simple high-accuracy position system are that simple system, flexible control, multi-point positioning, high accurate control, and low cost.
Description
Technical field
The utility model relates to a kind of positioning system, especially relates to a kind of simple high-precision positioning system.
Background technology
At present position control is very common in the industrial processes, the position of controlled device is controlled automatically and is run to predetermined target, and the position of arrival and the deviation between the assigned target position are remained within the allowed band.Following several modes commonly used position control on the engineering: 1, link stopper location, and this mode is usually used in hydraulic pressure or the pneumatic system, and its advantage is not need electronic control, directly obviously; Shortcoming is one-way trip, can't realize multipoint positioning, and impacts greatly, and usable range is narrow; 2, position transducer such as travel switch or approach switch add the AC frequency conversion kinematic train, and the advantage of this locator meams is that control mode is simple, and cost is low, and installation complexity and control accuracy were not high when shortcoming was multipoint positioning; 3, step-by-step control system or servo-control system, the advantage of this locator meams are that control accuracy is high, and shortcoming is system complex, and cost is high.The above localization method of comprehensive assessment and practical application, we need another localization method, and this kind localization method is simple in structure, and cost is low, and bearing accuracy is high, can satisfy most of positioning system.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, and cost is low, the simple high-precision positioning system that bearing accuracy is high.
The technical solution of the utility model is: a kind of simple high-precision positioning system, comprise Programmable Logic Controller, the operation screen, scrambler, frequency converter and mechanical drive actuating unit, comprise motor in the described mechanical drive actuating unit, reductor and dolly, interconnect between described Programmable Logic Controller and the described operation screen, described Programmable Logic Controller is controlled described frequency converter by circuit, described frequency converter is connected with described motor, described motor is connected with described speed reduction unit, described speed reduction unit is controlled the operation of described dolly, described scrambler is followed the motion Real-time Collection signal feedback of described dolly to described Programmable Logic Controller, described Programmable Logic Controller calculates in conjunction with the parameter preset of described operation screen again, the result is exported to described frequency converter, drag described trolley travelling thereby control described motor and speed reducer.
Advantage and the good effect that the utlity model has are:
1, system is simple, and nearly all middle-size and small-size Programmable Logic Controller (PLC) all standard configuration has high speed input signal point; Converter parameter is abundant in content, and the function setting of its digital input point is very convenient; Sensor is a scrambler, so only need a control cables just can realize, failure rate is low is installed simply.
2, control only need to just can realize the location, arbitrfary point by programming flexibly, can set within the specific limits multistation according to technological requirement on the operation screen, changes flexibly movement locus.
3, multipoint positioning only needs a scrambler, just can realize multipoint positioning by programming, need not to arrange other sensors again.Can also show in real time movement locus, motion state (time, linear velocity etc.) on the operation screen.
4, relatively approach or the control method of optoelectronic switch, control accuracy is high.The frequency acquisition of Programmable Logic Controller (PLC) high-speed counting input end can accurately receive the high-speed pulse signal that photoelectric encoder transmits up to 200kHz, cooperates the corresponding braking method of frequency converter, can arrive steadily, exactly the precalculated position.
5. relative servo-drive system, cost is low.Carry out position control with the method, can satisfy the dynamic control requirement of most of industry spot plant equipment, it is wealthy to be of wide application.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and the specific embodiments.
As shown in Figure 1, the utility model comprises Programmable Logic Controller, the operation screen, scrambler, frequency converter and mechanical drive actuating unit, comprise motor in the described mechanical drive actuating unit, reductor and dolly, interconnect between described Programmable Logic Controller and the described operation screen, described Programmable Logic Controller is controlled described frequency converter by circuit, described frequency converter is connected with described motor, described motor is connected with described speed reduction unit, described speed reduction unit is controlled the operation of described dolly, described scrambler is followed the motion Real-time Collection signal feedback of described dolly to described Programmable Logic Controller, described Programmable Logic Controller calculates in conjunction with the parameter preset of described operation screen again, the result is exported to described frequency converter, drag described trolley travelling thereby control described motor and speed reducer.
In use, on the operation screen, can set within the specific limits multistation according to technological requirement, change flexibly movement locus.Only need a scrambler, just can realize multipoint positioning by programming, need not to arrange again other sensors.Can also show in real time movement locus, motion state (time, linear velocity etc.) on the operation screen.The frequency acquisition of Programmable Logic Controller (PLC) high-speed counting input end can accurately receive the high-speed pulse signal that photoelectric encoder transmits up to 200kHz, cooperates the corresponding braking method of frequency converter, can arrive steadily, exactly the precalculated position.
Above embodiment has been described in detail the utility model, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
