The embodiment of the present invention discloses an environment protection system for a battery room, comprising: a temperature transmitter, which is used for monitoring the indoor temperature of the battery room, and when the indoor temperature is higher than a first preset indoor temperature, a variable frequency exhaust fan is started to cool down, When the indoor temperature is lower than the second preset indoor temperature, the heating device is started to heat up; the hydrogen concentration detection device is used to monitor the indoor hydrogen gas concentration in the battery room. When the hydrogen gas concentration exceeds the preset hydrogen gas concentration, the duration is longer than the first After a specified period of time, the variable frequency exhaust fan is started to reduce the concentration of hydrogen gas; the automatic sub-system is used to obtain the body temperature of the battery body and the operation signal of the battery pack charger, and send an alarm signal when the body temperature exceeds the preset body temperature. To the safety management control sub-system, adjust the wind speed and air volume of the variable frequency exhaust fan and the variable frequency supply air fan, and forward the operation signal to the safety management control sub-system for ventilation. |
