Abstract

The invention is applicable to the industrial communication technology field and provides a method and a system for interaction between a remote terminal device and a data transmission unit. The method comprises steps that: instructions issued by an RTU are received by a DTU; the instructions are parsed by the DTU, data contents are identified according to function codes in the instructions, response messages of the instructions are returned by the RTU, types of the instructions comprise a parameter query instruction, a parameter setting instruction, a parameter storing instruction, a reset instruction, an uplink data transparent transmission instruction, a downlink data transparent transmission instruction, a query state instruction, a GPIO control instruction, an upper and lower line control instruction and a receipt instruction. The method and the system have advantages of convenient maintenance and low cost.

Description

technical field [0001] The invention belongs to the field of industrial communication, and in particular relates to an interaction method and system between a remote terminal device and a data transmission unit. Background technique [0002] For traditional data transmission equipment, the interface provided to data acquisition equipment is to query and set parameters and reset the system. At present, each manufacturer of remote terminal devices generally has its own standard flagship product. This flagship product is generally simple. Responsible for the data transmission function, once it needs to be used in a certain industry, it is necessary to reposition the detailed functions and processes of the product according to the business application scenarios of the industry, such as the status query function, so that the software code of the product needs to be refactored, that is, usually The original design manufacturer (OriginalDesignManufacturer, ODM). Wireless data tran...
