Description

Intellectual Valve Controller

Technical field

The utility model relates to electronic applications, particularly, relates to a kind of Intellectual Valve Controller.

Background technology

Along with the development of industrial automation, the mode of traditional adjustment is no longer applicable in many occasions.Realize the industrial automation management of pipe network system, be unable to do without the topworks in this pipe network system of automatic valve.In some application scenario, be not only simple switch control rule to the control of valve, the various relations such as aperture control and flow that also relate to control, and this has higher requirement to the intelligent of electric valve executing mechanism controller.

And existing machinery valve adopts manual control, the problem of control overflow can not be reached accurately, and when valve is many, by manual control, efficiency comparison is low.

Utility model content

The purpose of this utility model is, for the problems referred to above, proposes a kind of Intellectual Valve Controller, to realize improving control efficiency and control accuracy, reduces the advantage of construction cost.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of Intellectual Valve Controller, comprise primary controller module, power module, valve resistance feedback module, switching value alarm output module, motor drive module, human-computer interaction module, analog acquisition load module, analog quantity feedback output module and communication module, power module, valve resistance feedback module, switching value alarm output module, motor drive module, human-computer interaction module are all electrically connected with primary controller module, and Analog input mModule and communication module are by Phototube Coupling and primary controller model calling.

Preferably, analog acquisition load module is 3 tunnels, and analog quantity feedback output module is 1 tunnel, and described communication module is 2 tunnels.

Preferably, communication module adopts RS485 telecommunication circuit.

Technical solutions of the utility model have following effect:

The technical solution of the utility model, proposes Intellectual Valve Controller, and by valve resistance feedback module acquires actual opening valve degree, analog acquisition load module gathers external analog amount signal; Communication module gathers the device data such as external sensor, gauge table; Thus run by motor drive module drive motor according to the external signal gathered.Thus reach raising control efficiency and control accuracy, reduce the object of construction cost.

Below by drawings and Examples, the technical solution of the utility model is described in further detail.

Accompanying drawing explanation

Fig. 1 is the theory diagram of the Intellectual Valve Controller described in the utility model embodiment;

Fig. 2 is the Intellectual Valve Controller use reference diagram described in the utility model embodiment;

Fig. 3 to Fig. 5 is the electronic circuitry of primary controller module in the Intellectual Valve Controller described in the utility model embodiment.

Embodiment

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.

As shown in Figure 1, a kind of Intellectual Valve Controller, comprise primary controller module, power module, valve resistance feedback module, switching value alarm output module, motor drive module, human-computer interaction module, analog acquisition load module, analog quantity feedback output module and communication module, described power module, valve resistance feedback module, switching value alarm output module, motor drive module, human-computer interaction module are all electrically connected with primary controller module, and described Analog input mModule and communication module are by Phototube Coupling and primary controller model calling.

Preferably, described analog acquisition load module is 3 tunnels, and described analog quantity feedback output module is 1 tunnel, and described communication module is 2 tunnels.

Preferably, described communication module adopts RS485 telecommunication circuit.

Human-computer interaction module is the human-computer interaction devices such as touch-screen.

Power module powers to whole controller system; Primary controller module acquires processing signals and control strategy; Valve resistance feedback module acquires actual opening valve degree thus valve opening is converted to electric signal, valve resistance feedback module by electric signal transmission to primary controller resume module, then export 4-20MA analog signals by analog quantity feedback output module, conveniently carry out Local or Remote control by network.Gather analog module and gather outside 4-20MA or 0-10V analog signals, such as thermometer, pressure gauge etc.; Communication module one tunnel exports primary controller module data and gathers the device data such as external sensor, gauge table to external host, a road; Motor drive module specifically processes according to primary controller module and exports drive motor operation; Man-machine interface monitors comprehensively, arrange whole controller system data.The network architecture of Intellectual Valve Controller as shown in Figure 2.

In central heating industry, Intellectual Valve Controller gathers supply water temperature, return water temperature and indoor temperature, demarcates acquisition circuit and valve locator data by man-machine interface setting, self-defined valve driving machine running, thus by-pass valve control aperture.Meanwhile, Intellectual Valve Controller exports 4-20MA simulating signal, facilitates other control system to carry out Local or Remote control.The fault such as stuck that may exist valve is carried out process and is reported to the police.To the user having on-the-spot Integration Bus demand, MODBUS agreement can be adopted to gather by RS485, and other control system also carry out Long-distance Control by another road RS485 channel.

Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
