[0036] In this solution, the control component is mainly applied to the fire protection of the electric bicycle shed, adopting a physical control form of non-integrated circuits. Among them, three detectors are used for temperature control monitoring in the electric bicycle shed. Among them, the first temperature control component 31 and the second temperature control component 32 form a first combination, and the third temperature control component 33 is the second combination, and the first combination and the second combination act together; the specific implementation includes: when the temperature-sensitive cable of the second temperature control component 32 detects an abnormal signal, the signal is transmitted to the temperature-measuring camera of the first temperature control component 31. Combining whether the temperature-measuring camera detects an abnormal signal, if the temperature-measuring camera also detects an abnormal signal, the control signal is given to the control box 4, and the water pump 22 and the corresponding zone valve 25 are controlled to work through the switch. This effect is to realize the connection between the water supply and the nozzle. If the temperature-controlled closed nozzle of the third temperature control component 33 also detects an abnormal signal, the closed nozzle will burst and the fire will be extinguished by spraying water. On the contrary, if the first temperature control component 31, the second temperature control component 32 and the third temperature control component 33 do not all detect abnormal signals, the water spraying for fire extinguishing will not be started.
