Referring to fig. 2 and 3, the control unit 5 is connected to a second timing unit 52, and the second timing unit 52 is configured to start timing when the control unit 5 receives the exhaust instruction, generate the warning instruction when the timing time exceeds a second timing threshold, stop timing, and return the timing time to zero. The control unit 5 is used for receiving the warning instruction and giving an alarm. The staff of being convenient for knows through alarm information that control unit 5 controlled ventilation unit 1 and filter unit 3 and started a period of time, but control unit 5 does not receive the braking instruction. The exhaust unit 1 and the filter unit 3 are in operation for a long time, which tends to shorten the life. And the control unit 5 does not receive a braking command indicating that the detection unit 4 is damaged or that the ammonia content in the pig house does not fall below a standard threshold. At the moment, the worker is reminded through alarming, so that the worker can find the abnormity of the pigsty odor treatment system or the abnormity of the pigsty in time, and the pig can be treated to ensure the healthy growth of the pig.
The second timing unit 52 is also used for stopping timing and resetting the timing time to zero when the control unit 5 receives the braking commands transmitted by all the detection units 4. The method is beneficial to reducing the false alarm rate and ensuring the normal operation of the pigsty odor treatment system. The first timing threshold and the second timing threshold are both set artificially. The first timing threshold is intended to periodically ventilate the pig house, and may be set at 24 hours, or 12 hours. The second timing threshold is intended to protect the exhaust unit 1 and the filter unit 3 and also to detect abnormalities of the system in time, and may be set to 2 hours or 5 hours.
Referring to fig. 2 and 3, the control unit 5 is connected to a frequency unit 53, the frequency unit 53 is configured to calculate an interval duration of the control unit 5 receiving the exhaust instruction transmitted by the same detection unit 4 twice, and generate an alarm instruction when the interval duration is less than an interval threshold.
