Abstract

The invention discloses a multifunctional intelligent controller, which comprises a proportion, integration and differentiation (PID) calculation unit and a communication port which can be used as a slave document control station (DCS) or a master DCS, wherein the communication port communicates with the PID calculation unit in two directions; the input end of the communication port is connected with an analog value input port and a digital value input port; the output end of the communication port is connected with a digital output port; and the digital output port is also connected with a display unit. According to the multifunctional intelligent controller, the problems that the function of the controller is relatively single, and users execute monitoring operation inconveniently in the prior art are solved; and therefore, multifunctional processing and a communication function are realized.

Description

A kind of multifunctional intellectual controller

Technical field

The present invention relates to a kind of intelligent controller.

Background technology

Along with the fast development of industry control industry, the control of various product requires also to have nothing in common with each other.Present intelligent controller function ratio on the market is more single-minded, and every kind of controller is accomplished single function, for example; Some can only be single the control temperature, the controlled pressure that some can only be single, some can also can control temperature by controlled pressure; But can't communication or the like numerous single controls, but further investigation reveals that, in a lot of Engineering Control, all needing multi-functional combination control; Should use communication, use analog acquisition again, when joining control, both can hosted use; Can do slave again and use, and to the processing of some data, existing intelligent controller can't reach unified in these areas.

Summary of the invention

In order to overcome the above-mentioned deficiency of existing intelligent controller, the present invention provides a kind of can realize that multi-functional processing can realize the multifunctional intellectual controller of communication function again.

The technical scheme that the present invention solves its technical matters is: a kind of multifunctional intellectual controller, comprise the PID computing unit, and comprise also and can do the communication port that the DCS slave station can be done main website again that described communication port is connected with the two-way communication of described PID computing unit;

The input end of described communication port also is connected with analog quantity input, digital input port, and the output terminal of said communication port also is connected with digital output, and described digital output also is connected with display unit.

Communication port not only can be done the DCS slave station but also can do main website, and during as the DCS slave station, slave computer parameter, write command value are gathered in the order of communication port response host computer during as main website.

Analog quantity input is gathered analog quantity; Transfer to the PID computing unit through communication port, have the A/D modular converter in the PID computing unit, calculate through carrying out PID to the analog quantity that collects after the analog to digital conversion; And reach the purpose that is controlled to be to equipment, realize the stable of system.And digital input port can be through the datum quantity of communication port write switch amount as PID calculating.Operation result is exported by digital output through communication port, and is shown by display unit.

Beneficial effect of the present invention is: the function that has solved the prior art middle controller is single relatively, and the inconvenient problem of policer operation to the user brings can realize that multi-functional processing can realize communication function again.

Description of drawings

Fig. 1 is a schematic diagram of the present invention.

Embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is done further explain.

With reference to Fig. 1, a kind of multifunctional intellectual controller comprises PID computing unit 1, also comprises and can do the communication port 2 that the DCS slave station can be done main website again, and described communication port 2 is connected with described PID computing unit 1 two-way communication;

The input end of described communication port 2 also is connected with analog quantity input 3, digital input port 4, and the output terminal of said communication port 2 also is connected with digital output 5, and described digital output 5 also is connected with display unit 6.

Communication port 2 not only can be done the DCS slave station but also can do main website, and during as the DCS slave station, slave computer parameter, write command value are gathered in the order of communication port response host computer during as main website.

Analog quantity input 3 is gathered analog quantity; Transfer to PID computing unit 1 through communication port 2, have the A/D modular converter in the PID computing unit 1, calculate through carrying out PID to the analog quantity that collects after the analog to digital conversion; And reach the purpose that is controlled to be to equipment, realize the stable of system.And digital input port 4 can be calculated 1 datum quantity through communication port 2 write switch amounts as PID.Operation result is exported by digital output through communication port, and is shown by display unit 6.

Claims

1. a multifunctional intellectual controller comprises the PID computing unit, it is characterized in that: comprise also and can do the communication port that the DCS slave station can be done main website again that described communication port is connected with the two-way communication of described PID computing unit;
