CN205229742U - Electric actuator's two serial ports structures of singlechip - Google Patents

Abstract

The utility model belongs to the technical field of electric actuator, especially, relate to an electric actuator's two serial ports structures of singlechip. Including having the singlechip of single serial ports, be connected with the TS5A23157 chip on the serial ports of this singlechip, the first pin of single chip microcomputer control gating and second pin respectively with two control input pin connections of TS5A23157 chip, two controls of TS5A23157 chip are exported pins and are connected to a serial port equipment and the 2nd serial port equipment respectively. The utility model provides an electric actuator's two serial ports structures of singlechip through insert the TS5A23157 chip on single serial ports of singlechip, utilizes this chip can switch according to the needs of port to the function of two tunnel different passageways, and with original serial ports signal connection TS5A23157 chip all the way, the recleaning selects to insert which passageway with it, has realized the expansion of serial ports, has avoided the big change to control module, has reduced the cost of reforming transform like this.

Description

A kind of single-chip microcomputer double-serial port structure of electric operator

Technical field

The utility model belongs to electric actuator technical field, particularly relates to a kind of single-chip microcomputer double-serial port structure of electric operator.

Background technology

The kernel control module of electric operator is generally by monolithic processor controlled, and along with the improving constantly of request for utilization of user, the communication interface used is needed also constantly to increase, the single-chip microcomputer of an original like this road serial ports just has to retrofit, remove the single-chip microcomputer selecting there is two-way hardware serial ports, so just need again to compare large adjustment to circuit and program.The adjustment process of above-mentioned complexity can bring the lifting of cost of products.

Utility model content

The utility model provides a kind of single-chip microcomputer double-serial port structure of electric operator, to solve the technical matters proposed in background technology for solving in known technology the technical matters that exists.

The technical scheme that the utility model is taked for the technical matters existed in solution known technology is: a kind of single-chip microcomputer double-serial port structure of electric operator comprises the single-chip microcomputer with single serial ports, the serial ports of this single-chip microcomputer is connected with TS5A23157 chip, first pin of Single-chip Controlling gating is connected with two control inputs pins of TS5A23157 chip respectively with the second pin, and two of TS5A23157 chip control output pin and are connected to first serial equipment and second serial equipment respectively.

Advantage of the present utility model and good effect are: the utility model provides a kind of single-chip microcomputer double-serial port structure of novel electric operator, by accessing TS5A23157 chip on single serial ports of single-chip microcomputer, utilize this chip can according to the function needing to be switched to the different passage of two-way of port, such by an original road rs 232 serial interface signal access TS5A23157 chip, which select again to be accessed passage, achieve the expansion of serial ports, avoid the large change to control module, reduce the cost of transformation.

Accompanying drawing explanation

Fig. 1 is structured flowchart of the present utility model.

Embodiment

For summary of the invention of the present utility model, Characteristic can be understood further, hereby lift following examples and be described in detail as follows:

Refer to Fig. 1, the utility model comprises the single-chip microcomputer with single serial ports, the serial ports of this single-chip microcomputer is connected with TS5A23157 chip, first pin of Single-chip Controlling gating is connected with two control inputs pins of TS5A23157 chip respectively with the second pin, and two of TS5A23157 chip control output pin and are connected to first serial equipment and second serial equipment respectively.

This circuit can use single serial-port Single-chip just can complete two-way serial communication; Expand the pin of single-chip microcomputer; Reduce the cost of scrap build.

The course of work:

The serial ports of single-chip microcomputer is connected with TS5A23157 chip, by the first pin and the second pin, the passage to TS5A23157 chip is selected simultaneously, when single-chip microcomputer will with first serial device talk time, first pin sets high by single-chip microcomputer, now microcontroller serial port is connected with first serial equipment by TS5A23157 chip, and carries out data communication.When single-chip microcomputer will with former second serial device talk time, the second pin sets high by single-chip microcomputer, and now microcontroller serial port is connected with second serial equipment by TS5A23157 chip, and carries out data communication.
