Background technique

In manufacturing industry and logistics field, with the need of automation, intelligentized development and process control and quality tracing Ask, fixed barcode reader using more and more extensive.In complicated site of deployment field, multiple bar code readings are generally required Device cooperates.Such as in logistical applications field, traditional scheme is that multiple bar code readings are made overall plans and coordinate by management information system Device work, it is done so that defect mainly have at 3 points:

Information system can not accomplish high-precise synchronization, development of information system quotient also without the experience of technique and field application, Cause the project implementation slow；

Information system physical communication interface quantity is limited, cannot access the multiple bar code readings for meeting application requirement simultaneously Device；

Information system processing delay is big, can not accomplish the high-precise synchronization of multiple access devices.

Currently, mainly connecting multiple barcode readers by independent networking equipment in industry, synchronously control, letter are realized The specialized functions such as breath acquisition, then accessed by the information system of the networking equipment and client.When connecting multiple equipment by networking, need The power supply and communication of multiple equipment are considered simultaneously.That there is also wiring is complicated, difficult in maintenance for current scheme, extension is difficult, at The problem of this etc..

Utility model content

The purpose of this utility model is to provide one kind can cascade bus networking interface module, pass through reasonable network topology Structure designs complete communications protocol, it is intended to solve the problems, such as that wiring is difficult, extension is difficult.

To achieve the above object, the technical solution of the utility model is as follows:

One kind can cascade bus networking interface module, including RJ45 bus interface, 15Pin equipment interface, conversion circuit, number According to bus and power supply buses, the 15Pin equipment interface connects data/address bus, 15Pin equipment interface and confession by conversion circuit The electrical connection of goddess of lightning's line there are two the RJ45 bus interface is set, passes through data/address bus and power supply buses series connection.

It further include auxiliary power supply interface in above scheme, the auxiliary power supply interface connects power supply buses, for providing 24V accessory power supply.

In above scheme, the conversion circuit is that RS232 turns RS485 circuit, for converting RS232 interface electrical standard For RS485 Interface Electrical standard.

In above scheme, the networking interface module is several, and the RJ45 bus interface of adjacent networking interface module is logical Cross cable cascade.

It further include bus interface control box in above scheme, the bus interface control box connection is located at primary group Network interface module.

In above scheme, the 15Pin equipment interface is for connecting image-type code reading device.

It further include shell in above scheme, the material of the shell is stainless steel metal plate.

The utility model can cascade bus networking interface module expanded flexibly using the topological structure of bus type networking, It at most can access nine equipment, it, can be according to specific station spread, in addition, the cable that networking uses is general when field conduct Logical cable, at low cost and connection is simple, and crystal head need to be only inserted into the RJ45 interface of networking module, flexible control connecting line Length.
