Programming system and method for integrated fan control system

Abstract

The invention discloses a programming system for an integrated fan control system and a programming method; it belongs to the field of fan control. The programming system comprises an algorithm module, a logic module, a SAMA universal module and a SAMA special module. The SAMA universal module includes a corresponding general SAMA diagram; the algorithm module includes the corresponding general logic program; the general SAMA diagram is linked with the corresponding general logic program through the call of the logic module; the SAMA special module includes a corresponding special SAMA diagram; the algorithm module includes the corresponding special logic program; the special SAMA diagram is linked to the corresponding special logic program by the call of the logic module. The invention applies the SAMA diagrams to the PLC programming, which lowers the threshold of programming, greatly shortens the development period, accelerates the development, and frees skilled engineers from the tedious work; at the same time, it makes it convenient to keep the process logic secret and to carry out debugging.

Description

technical field [0001] The invention relates to the field of fan control, in particular to a programming system and a programming method for an integrated control system of a fan. Background technique [0002] Wind energy is a renewable, non-polluting green energy. The development and utilization of wind energy can solve the shortage of conventional energy and power supply systems, as well as the environmental problems caused by the extensive use of conventional energy, which is of great significance. [0003] For a long time, in the field of wind power control systems, one of the problems that has plagued R&D personnel for a long time is that based on the consideration of product cost and supplier capacity, it is necessary for R&D personnel to apply a set of master control programs to PLC controllers from different manufacturers. The dilemma we are facing now is that the configuration methods of PLC control systems from different manufacturers are commonly used as follows: ...

Problems solved by technology

[0003] For a long time, in the field of wind power control systems, one of the problems that has plagued R&D personnel for a long time is that based on the consideration of product cost and supplier capacity, it is necessary for R&D personnel to apply a set of master control programs to PLC controllers from different manufacturers. The dilemma we are facing now is that the configuration methods of PLC control systems from different manufacturers are commonly used as follows: ladder diagram language, Boolean mnemonic language, function table diagram language, function module diagram language and structured statement description language, etc., although All PLC programs conform to the IEC61131 standard, but different manufacturers use different programming software environments, which require high quality programmers, which is not conducive to the promotion of software. Moreover, each engineer has different habits and different habits of writing programs. , resulting in the problem of non-standardized logic. With the upgrade of the PLC program, the logic becomes more and more complex, which makes maintaining a large-scale program require a senior engineer to spend a lot of time to complete, resulting in extremely high labor costs. big waste

[0004] The existing commonly used PLC programming includes: 1) ladder diagram: simple structure, difficult to implement complex algorithms; 2) C language: complex logic, difficult algorithms can be implemented, but not easy to maintain and upgrade

[0005] At present, there are several problems in the programming of the main control program: (1) There are many and complex control variables

(2) Programming software is difficult to understand and learning costs are high

(3) It is difficult to upgrade and maintain the program code

(4) The algorithm needs to be repeatedly written, modified, adapted and called
