Embodiment Construction
[0025] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0026] figure 1 It is a structural schematic diagram of the gas fire extinguishing controller in the embodiment of the present invention. Such as figure 1 As shown, the gas fire extinguishing controller is suitable for wind turbines, including the core control device and 8 loop devices, which can ensure that each independent protection area inside the fan can be assigned to a loop device, improving the safety factor of the entire fan.
[0027] figure 2 It is a structural schematic diagram of the loop device in the embodiment of the present invention. Such as figure 2 As shown, each loop device includes a data processing module, a feedback information input mod...

The invention discloses a gas extinguishment controller which is suitable for a wind generation set. The gas extinguishment controller comprises a core control device and eight loop devices, wherein each loop device comprises a data processing module, a feedback information input module, an instruction output module, a panel instruction receiving module, a communication module and corresponding port defence modules, wherein the feedback information input modules, the instruction output modules, the panel instruction receiving modules and the communication modules are respectively connected with the corresponding port defence modules, and the port defence modules are used for carrying out port defence on input-output signals of the loop devices. Due to the adoption of the technical scheme of the invention, the gas extinguishment controller provided by the invention has the advantages that the safety factor of the whole fan is improved, the space of a cabinet body is saved, an electro magnetic compatibility property is not influenced, and a condition that the controller can normally operate in the fan is guaranteed.
Description
technical field [0001] The invention relates to the technical field of wind power generation, in particular to a gas fire extinguishing controller. Background technique [0002] There are many fire hazards inside the fan. At present, there are no or few intelligent fire-fighting equipment installed in wind farms, and most of them only put two dry powder fire extinguishers in the wind turbine cabin. The wind turbine is unattended, and the fire cannot be detected early. If a fire occurs, it is easy to cause huge losses. The automatic fire-fighting system monitors possible fire hazards inside the fan in real time, and notifies the gas fire extinguishing controller to control the gas fire extinguishing medium to extinguish the fire that has occurred. [0003] The electromagnetic environment inside the fan is relatively harsh. Due to the existence of high-frequency equipment and high-power equipment, it is difficult to avoid space electromagnetic radiation and conduction distur...
