摘要（英）：

The utility model relates to the technical field of power wireless data terminals, in particular to a special 230MHz Mobitex master-slave redundancy wireless data terminal for power. The special 230MHz Mobitex master-slave redundancy wireless data terminal is characterized by comprising an ARM main processor, a baseband processing DSP (Digital Signal Processing) chip I, a baseband processing DSP chip II, a radio frequency modulator-demodulator I, a radio frequency modulator-demodulator II, a channel selecting unit, a transmitting module, a receiving module and an MIM02*2 antenna, wherein the ARM main processor, the baseband processing DSP chip I and the baseband processing DSP chip II form a master-slave structure; and the baseband processing DSP chip I is the backup of the baseband processing DSP chip II, and the baseband processing DSP chip II also can be taken as the backup of the baseband processing DSP chip I. Compared with the prior art, the terminal provided by the utility model has the advantage that based on 230MHz frequency band resources of a Mobitex opened protocol stack and a power system, the upgrade and the reconstruction the 230MHz data radio station and 800MHzMobitex wireless communication system of the power system are facilitated.
