The invention discloses a clock synchronization device and a method used for a fan control system. The clock synchronization device and the method used for the fan control system comprise a singlechip, a satellite clock signal receiving module which is connected with the singlechip, a power circuit, a clock crystal oscillator, and a data port circuit, wherein the data interface circuit is used for connecting the fan control system. The singlechip comprises a clock benchmark module which is connected with the satellite clock signal receiving module and used for receiving the satellite clock signals, a time keeping module which is connected with the clock benchmark module and the clock crystal oscillator, and a timing module which is connected with the clock benchmark module and used for synchronizing the clock benchmark module and the satellite clock signals at fixed time. According to the clock synchronization device and the method used for the fan control system, clock signals of a clock signal broadcasting system of a satellite are used as the clock benchmark, automatic clock synchronization is conducted once every other second, the singlechip time keeping is used in two continuous time intervals, the accurate time received from the timing keeping is transmitted to the fan control system to conduct the clock synchronization through the data port circuit, and the clock synchronization is accurate. The singlechip can be replaced by Unified Communications (UC).
Description
[0001] technical field [0002] The invention relates to the technical field of wind power control, in particular to a timing device and method applicable to a wind turbine control system. Background technique [0003] In the fan control system, when the fan fails or the system needs to be corrected, it is necessary to record the current time of the system while recording the fault. Therefore, an accurate clock system is required to provide the fan main control PLC or peripheral data recording equipment. In addition, different wind turbines use different control systems, and the interfaces may not be the same, so the timing device with a single interface cannot meet the needs of various types of wind turbine control systems. Contents of the invention [0004] The main purpose of the present invention is to provide a timing device and method that can be used in a wind turbine control system, which can provide an accurate clock system when the wind turbine fails or needs syste...
