The utility model relates to an improved total suspended particle (TSP) advanced geological forecast signal triggering and receiving system, which comprises a delay measurement instrument, wherein the delay measurement instrument and explosive with a detonator are connected with a closed loop, simultaneously, the delay measurement instrument is also respectively connected with a main machine and a trigger, and the trigger is connected with the detonator; and the trigger is also connected with a primer. A timer circuit and a signal triggering circuit are arranged inside the delay measurement instrument, and the timer circuit is respectively connected with a conducting wire closed loop which is wound on the explosive, an external trigger and an internal signal triggering circuit; and the signal triggering circuit is connected with an external main machine. Due to the adoption of the improved TSP advanced geological forecast signal triggering and receiving system, the requirement on the type of the detonator is low, the system is convenient for the in-situ construction, the time error between the traditional signal triggering and receiving way can be reduced, and the forecast precision can be improved.
