Ventilation systems are one of the key devices in modern standardized farms. The ventilation system not only can timely discharge harmful gas generated in the farm and introduce fresh air, ensure the air quality and simultaneously meet the requirements of livestock growth and development, but also can radiate heat and water vapor generated by metabolism of livestock and maintain ideal temperature and humidity environment in the farm.

With the development of the breeding industry, farms tend to be automated and intelligently managed, and a large amount of electrical equipment is used to meet production requirements. However, this also increases the chances that the farm will suffer sudden electrical faults, such as overvoltage, leakage, short circuit, etc., which are very prone to power failure. Once the power of the farm is cut off, the ventilation equipment cannot normally operate, so that the air quality and the temperature and humidity environment in the farm can be seriously influenced, and even the safety of livestock and poultry is threatened.

In the process of driving the ventilation equipment 100 for a long time, the main control circuit 102 may have power failure, line failure, component failure or power overload, so the emergency control circuit 202 is arranged to compensate for the potential problem of the main control circuit 102, when the main control circuit 102 fails and cannot work normally and the temperature of the farm exceeds the preset temperature to influence the livestock and poultry cultivation, the emergency control circuit 202 is communicated, and the ventilation equipment 100 is driven by the emergency power supply 201 to be started in time, so that the situations of insufficient ventilation of the farm and even the influence on the safety of the livestock and poultry caused by the failure of the main control circuit 102 are effectively reduced.

In some embodiments, as shown in FIG. 2, the emergency control circuit 202 includes an emergency controller 2021, one end of the emergency controller 2021 is connected to the ventilation device 100, and the other end is connected to the emergency power supply 201, so that when the main control circuit 102 fails, the emergency power supply 201 supplies power and controls the ventilation device 100 to be turned on or off through the emergency controller 2021, so as to ensure the minimum ventilation volume of the farm, and reduce the loss caused by the failure of the main control circuit 102.
