Abstract
The invention provides a universal digital change-over switch based on CCLink communication for solving the problem that the traditional universal change-over switch cannot achieve digital communication. The universal digital change-over switch consists of a universal change-over switch and a communication control part, wherein the communication control part comprises a power circuit, a digital quantity input unit and a CCLink communication interface. The universal digital change-over switch with the CCLink communication can reduce cable connection and lower costs. The anti-interference ability of the CCLink digital communication is better than that of former level transmission. The state input can by carried out by selecting the state supporting 8-, 16-, 32-circuit switches, and each circuit is provided with a corresponding state display interface. The digital change-over switch improves the reliability and safety, is synchronously convenient for mounting, maintenance and control, saves a large amount of expenses, and greatly improves the function of the digital change-over switch in the field of industrial automization while providing conveniences for users.
Description

Background technology
Universal seclector is the master control electrical apparatus of a kind of multi-gear type, multisection type, is widely used in the industries such as electric power, metallurgy, petrochemical industry, light textile, and major function is the conversion to multiple and most amount circuit.For example be used for commutation, measurement, the control of conversion, voltmeter and the ammeter of various control circuits, far distance controlled and the separating brake of primary cut-out operating mechanism and the control of closing a floodgate of controller switching equipment, also can use etc. as servomotor speed change and commutation control.
Existing universal seclector is realized the conversion of control circuit, traditional method is with the contact signal of universal seclector and various relay, contactor is connected, electrical interlock conversion by physics, finish the realization of control task and controlled target, more common application process is that the contact signal with universal seclector is linked into programmable logic controller (PLC), the input/output module of peripheral control units such as dcs, pass through the logical operation of this peripheral control unit again, to control the result and output to various relays, corresponding electric wiring is controlled and changed.But along with the application of field bus technique at industrial control field, the networking of automated system, total linearize have become main trend, in the use of existing universal seclector, no matter be the mode that traditional electrical interlock is controlled, still adopt peripheral control unit to realize the mode of interlocked control, all digital communication can not be carried out, thereby the networking of modernized industrial system, total linearize requirement can not be satisfied.
Because the status signal that universal seclector produces is a bit data, there is not analog quantity, and the remote I/O station communication control chip of CCLink, be mainly used in bit data input, output and transmission, therefore the various self-diagnostic functions relevant with total line traffic control that chip internal is integrated, can carry out under the prerequisite of digital communication, at these three aspects of reliability of bit data transmission, reduction system cost and raising system, communication has incomparable advantage based on CCLink in employing.
Therefore, be desirable to provide a kind of digitlization universal seclector, realize transmitting the state information of universal seclector to remote control equipment, show and interlocked control in the mode of digital communication based on CCLink communication.
Up to the present, still there is not the correlative study report.
Summary of the invention
The present invention is directed to existing universal seclector and can't realize the problem of digital communication, purpose is to provide a kind of digitlization universal seclector based on CCLink communication.
The present invention is based on the digitlization universal seclector of CCLink communication, form by universal seclector (2) and Control on Communication part (1), Control on Communication part (1) comprises power circuit (4), digital quantity input unit (3) and CCLink communication interface (5): universal seclector (2) links to each other with digital quantity input unit (3), produces on off state; Digital quantity input unit (3) links to each other with CCLink communication interface (5), the core CCLink communication control chip that the acquisition state data are sent in CCLink communication interface (5) circuit is handled, link to each other with remote equipment by a telecommunication cable by CCLink communication interface (5) then and carry out the transmission of digital information, power circuit (4) links to each other with CCLink communication interface (5), for communication chip provides working power.
Digital quantity input unit (3) is selected the light-coupled isolation device for use;
CCLink communication interface (5) is that the regulation according to standard GB/Z 19760-2005 designs realization;
CCLink communication interface (5) mainly is made of CCLink communication control chip, 485 chip for driving and filter;
The CCLink communication control chip can select to support the input of 8,16 or 32 way switch states in the CCLink communication interface (5), and each road all has corresponding state display interface.
Core CCLink communication control chip among the present invention in CCLink communication interface (5) circuit is mainly used in bit data input, output and transmission, the various self-diagnostic functions relevant that chip internal is integrated with total line traffic control, therefore, do not need microprocessor just can realize the digital communication of CCLink and the diagnostic detection of total line traffic control.
Description of drawings
Fig. 1 is based on the schematic diagram of the digitlization universal seclector of CCLink communication.
Fig. 2 is based on CCLink communication interface connection layout in the digitlization universal seclector of CCLink communication.
The advantage that the present invention has with good effect is: being somebody's turn to do the digitlization universal seclector of communicating by letter with CCLink, is the CCLink intelligence I/O equipment with CCLink digital communication, can reduce cable and connect, and reduces cost. CCLink digital communication, antijamming capability are better than former level and transmit. Can select to support the input of 8,16,32 way switch states, and each road all has corresponding status indications interface. This universal seclector improves reliability and security, is convenient to simultaneously install, safeguards and control, has saved a large amount of expenses, in the user friendly while, has greatly improved its effect at industrial automation.
