The invention discloses a centralized room gas detection system. Through a pipeline connected with a periodic cyclic gas extraction detection device and under the control of a control device, the periodic cyclic gas extraction detection device sequentially and cyclically extracts gases in each room into the periodic cyclic gas extraction detection device through electric exhaust fans for detection and then detects the concentration of the detected gases in each room. In such a way, the concentration of the detected gases in a plurality of rooms can be detected by only one or one group of gas detection probes, which reduces the number of the used gas detection probes and saves the one-time investment of mounting cost. Moreover, the gases in the rooms are extracted through the electric exhaust fans which can be arranged in a hidden way so as to keep the attractive appearance of the rooms. Simultaneously, the periodic cyclic gas extraction detection device can be arranged at any position outside the rooms so as to be convenient to mount and check. Finally, for the similar reasons in use, if the gas detection probes need replacing, only one or one group of gas detection probes is replaced, which greatly reduces use cost.
