Abstract
The utility model discloses a mainboard discernment expansion board that electric actuator used relates to electric actuator equipment technical field, its characterized in that: at least, include: the model is PIC18F46K80's singlechip, RS485 communication interface, relay extension discernment interface, and PROBUS bus discernment interface, wherein: above -mentioned singlechip passes through RS485 communication interface and PROBUS bus discernment electrical connection interface, above -mentioned singlechip and relay extension discernment electrical connection interface. By adopting the above technical scheme, the misunderstanding that this patent can reduce the customer when operating, simultaneously for the operation menu is more succinct, more convenient, and connect different function versions according to customer's needs, has reduced the cost of executor.
Description
Technical field
This utility model is related to YE equipment technical field, more particularly to a kind of mainboard of YE
Identification expansion board.
Background technology
It is known that executor (final controlling element) is to receive in automation equipment to control
Information the device to controll plant applying control action.Executor is also directly to change to manipulate in control system forward path to become
The instrument of amount, is made up of actuator and governor motion.Wherein: the master control borad of executor is carried out one of vitals of device,
Found by practice: traditional master control borad has following defect: 1, because master control borad function is many, but limited space, so
Need multiple expansion board；2nd, master control borad actions menu is many, when expansion board does not connect upper master control borad, also has in a menu
The corresponding operating function of these expansion board, easily misleads client.
Utility model content
The technical problems to be solved in the utility model is: a kind of mainboard identification expansion board of YE is provided, should
The mainboard identification expansion board of YE can overcome the technological deficiency pointed by background technology.
This utility model is adopted the technical scheme that by solving technical problem present in known technology:
A kind of mainboard identification expansion board of YE, at least includes:
The single-chip microcomputer of model pic18f46k80；
Rs485 communication interface；
Relay extension identification interface；
And probus bus identification interface；Wherein: above-mentioned single-chip microcomputer passes through rs485 communication interface to be known with probus bus
Other interface electrical connection；Above-mentioned single-chip microcomputer extends identification interface with relay and electrically connects.
This utility model has the advantages and positive effects that:
By adopting technique scheme, this patent can reduce misunderstanding during guest operation；Simultaneously so that actions menu
More succinct, it is more convenient；And need to connect different function versions according to client, decrease the cost of executor.

Specific embodiment
For utility model content of the present utility model, feature and effect can be further appreciated that, hereby enumerate following examples, and
Cooperation accompanying drawing describes in detail as follows:
Refer to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of mainboard identification expansion board of YE, comprising: model
The single-chip microcomputer of pic18f46k80；Rs485 communication interface；Relay extension identification interface；And probus bus identification interface；
Wherein: as shown in Figure 1: above-mentioned single-chip microcomputer passes through rs485 communication interface and identifies that interface electrically connects with probus bus；Above-mentioned monolithic
Machine extends identification interface with relay and electrically connects.As shown in Figure 2: the cpuin terminal of single-chip microcomputer is electrically connected with extension plate interface j5；
The rxd terminal of single-chip microcomputer, de terminal, txd terminal are electrically connected with the max485 chip of serial communication circuit；As shown in Figure 3: monolithic
The rxd terminal of machine, de terminal, txd terminal are electrically connected with the max485 chip of rs485 communication interface..
In the preferred embodiment: include 2 kinds of expansion board, a kind of is probus bus extension plate, and one kind expands for relay
Panel；Wherein:
The recognition methodss of probus bus extension plate: control system communication uses rs485 bus communication mode,
Probus bus extension plate has the function of rs485 communication, when expansion board being connected in rs485 bus, by agreement master control
Plate has been known that expansion board connects, and shows respective operations option in a menu.
Relay expansion board recognition methodss: have pull-up resistor r1 on 7 feet of relay expansion board contact pin j1, when expansion board connects
It is connected on master control borad, when the cpu of master control borad judges 5 feet of j1 for high level, illustrate that relay expansion board has connected and corresponding aobvious
Show its actions menu.
Above embodiment of the present utility model is described in detail, but described content has been only of the present utility model preferable
Embodiment is it is impossible to be considered for limiting practical range of the present utility model.All according to this utility model application range made equal
Deng change and improvement etc., all should still belong within patent covering scope of the present utility model.
