Embodiment Construction

[0037] Firstly, the device interconnection system based on device description provided by the present invention is described, see figure 1 As shown, the control device is interconnected with one or more controlled devices of the same type or different types through an access network, wherein the controlled device includes an input device and / or an output device, and the access network may be a system bus form.

[0038] The control device includes a device description information storage unit for storing the description information of the controlled device. Such as figure 2 As shown, the device description information storage unit includes several device description information storage subunits, which are respectively used to store description information of different controlled devices. The identification of each sub-unit can be in one-to-one correspondence with the physical address of the controlled device, and the storage space of the storage unit can be expanded or reduc...

Abstract

The invention discloses an apparatus interconnection method, a device and a system thereof. The apparatus interconnection system comprises a system configuration device, a control apparatus and at least one controlled apparatus; the system configuration device is used for generating descriptive information of the controlled apparatus according to the configuration operation, and the descriptive information of the controlled apparatus comprises apparatus type information, apparatus configuration information and apparatus communication information; the control apparatus is used for receiving and storing the descriptive information of the controlled apparatus sent by the system configuration device; the control apparatus establishes a data connection with a controlled apparatus which is newly accessed and detected in an access network according to the descriptive information of the controlled apparatus, and sends the stored configuration information of the controlled apparatus to the controlled apparatus which is in data connection; and the controlled apparatus comprises an input apparatus and / or an output apparatus for performing input or output operation according to the configuration information sent by the control apparatus.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a method, device and system for interconnecting equipment. Background technique [0002] For various control systems used in process control, such as distributed control system (DCS), fieldbus control system (FCS), etc., its basic components include: input devices, output devices and control devices. After the input device measures the field signal, it preprocesses the signal and sends it to the control device as input real-time data. After the control device analyzes and processes the received input real-time data, it runs the control algorithm to calculate the real-time control required The data is sent to the output device, and the output device converts the received output real-time data into a standard signal and sends it to the on-site execution device to perform control operations. [0003] According to different types of measurement signals, input devices can b...
