Modularized remote terminal unit (RTU) and rapid customization method thereof

Abstract

The invention discloses a modularized remote terminal unit (RTU) and a rapid customization method thereof. The modularized RTU comprises an ontology module, a power module, a general input / output (I / O) interface module and a special function interface module, an external interface of the ontology module is divided into a general I / O interface area and a special function interface area which is used for being connected with other modules, a special function module comprises a special function signal I / O interface area and interface areas, the interface areas are cascaded among the modules, the modules are detachably connected, the ontology module and other modules are connected through the special function interface area, other modules are mutually connected through the interfaces areas which are cascaded among the modules, and automatic identification and configuration after module assembly are completed by the ontology module. According to the modularized RTU and the rapid customization method thereof, a basic interface unit of the RTU is generalized, the management of a central processing unit is intelligentized, the general and intelligentized ontology module is constructed, other external device modules can be customized according to specific applications and detachably assembled and disassembled on the basis of the ontology module, the rapid and flexible assembly of the RTU is achieved, and application functions are rapidly added and reduced.

Description

[0001] technical field [0002] The invention relates to a remote terminal unit (Remote Terminal Units, RTU), in particular to a modularized RTU and a rapid customization method thereof. Background technique [0003] With the development of modern industry, it has been difficult to meet the needs of the production process by manually monitoring and collecting various environmental parameters on site. Especially in engineering fields such as real-time control, this problem is particularly prominent. In order to solve this problem, Remote Terminal Units (RTUs), which have the characteristics of various on-site parameter collection, long-distance communication, and adaptation to harsh environments, have emerged as the times require. RTU integrates remote signaling, telemetry, and remote control functions, and is widely used in various data acquisition and monitoring control (Supervisory Control And Data Acquisition, SCADA) systems. [0004] Usually, RTU is composed of central...

Problems solved by technology

But without exception, the structure is highly application-related, tightly coupled, and poor in scalability

It is impossible to achieve flexible and fast expansion of functions in the true sense, and it is difficult to meet the new features of modern engineering application requirements, changeable requirements, and short construction period

Although there are some RTU products with rich functions on the market, these products have all functions solidified inside the product when they leave the factory, and users cannot selectively remove redundant functions, resulting in increased equipment costs and energy consumption. Difficult to integrate these redundant functions, resulting in waste of resources

The above factors limit the flexible application of existing RTU products
