Embodiment Construction

[0047] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0048] like figure 1 As shown, the present invention includes two parts of control master station and I / O module, namely:

[0049] Control the master station to run the wireless LAN field bus protocol stack, manage the I / O module through the I / O module controller to complete the distributed I / O control, and also be responsible for sending and receiving data to Ethernet through the wireless LAN transmission module; realize wireless transmission of data And any movement within the effective range, and realize seamless interconnection with Ethernet.

[0050] The I / O module is connected to the control master station through the general I / O terminal base to complete the collection and conversion of field signals. Each I / O module supports hot swap and plug and play; each I / O module Both include a configuration information memory (including information such as mod...

Abstract

This invention relates to auto-control field, which in detail is used to a wireless LAN on-site bus net control station. It comprises main control station and I/O module, wherein, its main control station runs the wireless LAN on-site bus agreements and accomplishes the distribution I/O control through I/O module controller and receives and transmits data to Ethernet through wireless LAN transmission module. The I/O module is to accomplish the collection and conversion of the on-site signals. It is based on intelligence control device of the wireless Ethernet and turns the DCS total distributed system structure into new type of total distribution structure to completely distribute the control into the on site by network control station. This invention especially applies to old industry control system reconstruction to make it possible for old enterprises to enter the new time of on-site bus.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a wireless local area network field bus network control station for industrial field control. Background technique [0002] Fieldbus Control System (FCS, Fieldbus Control System) has become one of the development directions of new industrial control systems in the future because of its openness, decentralization and interoperability. However, there are still many problems in the development of fieldbus technology at present, the most important one is that a unified protocol standard has not been formed. Due to the vast differences between different fieldbus communication protocols, it is very difficult to realize the interconnection and interoperability between different bus products, which not only makes it difficult to reflect the superiority of the fieldbus control system, but also increases the technical and investment risks of user applications, which is not conducive The d...
