Description

Technical Field

[0001] The utility model relates to the field of industrial automation information transmission, in particular to a multi-protocol and expandable bus valve island. Background Art

[0002] A bus valve island is usually a module that integrates communication and control functions for controlling solenoid valves. By integrating the two module functions, electrical, pneumatic, and mechanical functions are integrated together, effectively reducing the wiring difficulty of solenoid valves and the complexity of overall system construction, which is beneficial to system function debugging and performance detection. Based on common field industrial bus communication protocols such as Profinet, EtherCAT, Ethernet I / P, CC-Link IE Field Basic, etc., the control and status detection of solenoid valves are realized, and specific control applications are achieved by using solenoid valves.

[0003] In the prior art, usually the field bus protocol used by a group of valve islands is fixed to one kind, and the number of solenoid valves controlled by the valve island is also limited. When there are different bus protocols actually on site, multiple groups of valve islands need to be used. Therefore, there is a need to be compatible with multiple industrial bus protocols and expand solenoid valves in practical applications. Summary of the Utility Model

[0004] In order to make up for the deficiencies of the prior art, the utility model provides a multi-protocol and expandable bus valve island, which can support multiple communication protocols, can realize the expansion of a specific number of solenoid valves, reduce costs, and improve the problems existing in the prior art.

[0005] The utility model is realized by the following technical solutions:

[0006] A multi-protocol and expandable bus valve island includes a main control module and a gas circuit board module. The main control module is detachably fixed on the gas circuit board module. The main control module includes a power supply module, a communication module, a control module, and a status indication module. The gas circuit board module includes a gas circuit board and a number of groups of IO interfaces arranged on both side walls of the gas circuit board. A number of groups of jacks are also provided on the gas circuit board, and each group of jacks corresponds to each group of IO interfaces one by one. A solenoid valve is plugged into each jack.

[0007] Further optimized, a fixing shell is provided outside the main control module, and the fixing shell is fixed to the gas circuit board by screws.

[0008] Further optimized, the solenoid valve is electrically connected to the gas circuit board and the main control module through the IO interface.

[0009] Further optimized, the power supply module includes a power interface and a power conversion circuit for connecting a 24V switching power supply.

[0010] Further optimized, the communication module uses an RJ-45 interface.

[0011] Further optimized, the control module uses a NetX series industrial bus communication chip.

[0012] Further optimized, there are 5 - 20 groups of both the IO interfaces and jacks. The IO interfaces are pluggable terminal blocks with a terminal pitch of 3.8 mm. The input part of the IO interfaces uses a digital input type, compatible with PNP and NPN inputs, and the output part uses a digital output.

[0013] Further optimized, there are several groups of screw holes on the air circuit board. The solenoid valves are fixed to the air circuit board with screws, and fixing holes are provided at both ends of the air circuit board.

[0014] The beneficial effects of the present utility model are as follows:

[0015] The present novelty proposes a multi - protocol, expandable valve island. The control module uses a NetX series industrial bus communication chip, supporting multiple mainstream communication protocols (such as Profinet, EtherCAT, CC - Link, CC - Link IE). The main control module is detachably plugged on the air circuit board module. The air circuit board can customize different sizes according to the models of various solenoid valves. When customizing the air circuit board, it can be customized to expand 5 - 20 groups to meet different requirements.
