The invention discloses a hybrid wireless elevator emergency help calling system. The emergency help calling system comprises a plurality of elevator hoistway warning subsystems, an early warning extension set, a GSM host, a frequency modulation early warning terminal and a mobile network early warning terminal. The elevator hoistway warning subsystems comprise a plurality of warning interphones arranged on an elevator, the early warning extension set is provided with a UHF wireless transceiver at the same time, the interphones are connected with the early warning extension set, and the early warning extension set is connected with the UHF wireless transceiver. The elevator hoistway warning subsystems are in wireless connection with the GSM host and the frequency modulation early warning terminal through the UHF wireless transceiver, and the mobile network early warning terminal is in wireless connection with the GSM host. The hybrid wireless elevator emergency help calling system has the advantages of being low in cost, easy to construct and maintain, long in coverage distance, high in timeliness, large in system capacity and high in mobility.
