Problems solved by technology

In the seismic industry, there is no dedicated 3G wireless data transmission equipment with complete functions (the development and application of 3G modules). Some seismic stations use some general wireless routers to realize the 3G wireless data transmission function. The advantage of using this general equipment is that The system construction time is short, the short-term investment is small, the results are quick, and the debugging is convenient; but the disadvantages are also very obvious, that is, it is not conducive to future function development, and the maintenance cost is high

Abstract

The invention provides a wireless data transmission monitoring meter of an earthquake prediction station, which aims at solving the problems that some universal wireless routers achieve a 3G (Third Generation) wireless data transmission function, functional development in future is not facilitated, and the maintenance cost is high. The wireless data transmission monitoring meter is characterized in that a singlechip is fixed in a housing, connected with a network module, connected with a WCDMA (Wideband Code Division Multiple Access) module by an interface chip, connected with an RS232 (Recommended Standard 232) interface by the interface chip, and connected in parallel with an alternating current solid relay unit, a contact relay unit and a direct current solid relay unit on a driving circuit. The wireless data transmission monitoring meter has the benefits that real-time monitoring on earthquake prediction equipment is achieved; the problem of an equipment failure is solved; a 3G wireless data transmission function of the wireless data transmission monitoring meter is enabled when a transmission channel fails, so that discontinuous transmission of an earthquake prediction signal is achieved; once a wired channel fails, a wireless channel can immediately exert an earthquake prediction data transmission function; and the wireless data transmission monitoring meter further has the characteristics of simplicity and convenience in operation, and low cost.

Description

technical field [0001] The invention relates to the field of wireless data transmission, in particular to a wireless data transmission monitor for a seismic station. Background technique [0002] With the development of society, the means of data transmission are changing with each passing day, and people have leapfrogged from wired transmission and wireless transmission to modern high-speed 3G transmission. [0003] The application of remote monitoring and 3G wireless data transmission in the seismic system is still in its infancy. Shi Xiaohui et al. have explored the combined application of GPRS wireless transmission mode and wired transmission mode; Zhu Xiaoyi et al. Wired control is used to complete the realization of the remote monitoring function interface of the seismometer. In the seismic industry, there is no dedicated 3G wireless data transmission equipment with complete functions (the development and application of 3G modules). Some seismic stations use some gene...
