The current SMS system of the Liaoning Seismic Network can only send messages to China Mobile users; in addition, there are too many manual operations during the process of sending short messages, which affects the transmission efficiency and accuracy. To solve these problems, we developed a new seismic short message fast-transmission system based on Web Service and PyQt. The system can automatically generate seismic short messages and select the receiving personnel, and can be flexibly modified according to special circumstances. In addition, viewing the status of the sent messages is easy. The system configuration is straightforward and the system can automatically generate a running log, which assists with maintenance of and fault-finding for the system.
