Description

Intellectual Valve Controller

Technical field

The present invention relates to electronic applications, particularly, relate to a kind of Intellectual Valve Controller.

Background technology

Along with the development of industrial automation, the mode of traditional adjusting is no longer applicable in many occasions.Realize the industrial automation management of pipe network system, be unable to do without the topworks in this pipe network system of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

And existing machinery valve adopts manual control, can not reach accurately and control the problem requiring, and when valve is many, by manual control, efficiency is lower.

Summary of the invention

The object of the invention is to, for the problems referred to above, propose a kind of Intellectual Valve Controller, to realize, improve control efficiency and control accuracy, reduce the advantage of construction cost.

For achieving the above object, the technical solution used in the present invention 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 to primary controller module, and analog input module is isolated with primary controller module and is connected by photoelectricity with communication module.

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 solution of the present invention has following effect:

Technical scheme of the present invention, has proposed Intellectual Valve Controller, by valve resistance feedback module, gathers actual opening valve degree, and analog acquisition load module gathers external analog amount signal; Communication module gathers the device datas such as external sensor, gauge table; Thereby move by motor drive module drive motor according to the external signal gathering.Thereby reach, improve control efficiency and control accuracy, reduce the object of construction cost.

Below by drawings and Examples, technical scheme of the present invention is described in further detail.

Accompanying drawing explanation

Fig. 1 is the theory diagram of the Intellectual Valve Controller described in the embodiment of the present invention;

Fig. 2 is that the Intellectual Valve Controller described in the embodiment of the present invention is used reference diagram;

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

Embodiment

Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein, only for description and interpretation the present invention, is not intended to limit the present invention.

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 to primary controller module, and described analog input module is isolated with primary controller module and is connected by photoelectricity with communication module.

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 is given whole controller system power supply; Primary controller module acquisition process signal and control strategy; Thereby valve resistance feedback module gathers actual opening valve degree valve opening is converted to electric signal, valve resistance feedback module by electric signal transmission to primary controller resume module, then by analog quantity, feed back output module output 4-20MA analog signals, conveniently by network, carry out Local or Remote control.Gather analog module and gather outside 4-20MA or 0-10V analog signals, such as thermometer, pressure gauge etc.; Communication module one tunnel output primary controller module data gathers the device datas such as external sensor, gauge table to external host, a road; Motor drive module is specifically processed the operation of output drive motor according to primary controller module; Man-machine interface monitors comprehensively, arranges 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, by man-machine interface, is set and is demarcated acquisition circuit and valve locator data, uses pid control algorithm, self-defined valve driving machine running, thereby by-pass valve control aperture.Meanwhile, Intellectual Valve Controller output 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 processed warning.To there being the user of on-the-spot Integration Bus demand, can adopt MODBUS agreement to gather by RS485, and other control system also can carry out Long-distance Control by another road RS485 channel.

Finally it should be noted that: the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although the present invention is had been described in detail with reference to previous embodiment, for a person skilled in the art, its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
