Abstract

The invention discloses a time synchronization device, which comprises a Beidou antenna, a Zigbee antenna, a GSM antenna and a host. The host comprises a back board, a Beidou board, an FPGA module, a Zigbee module and a GSM module. The Beidou antenna transmits radio-frequency signals to the Beidou board; the Beidou board processes the signals and then, transmits a generated time signal, a second pulse signal and a set time delay signal to the FPGA module; and the FPGA module generates and outputs delay pulses, and selectively transmits the time delay signal set in the Beidou board to the Zigbee module or the GSM module according to data transmission distance. Through dual-mode communication of the GSM module and the Zigbee module, stability of a device time service function is ensured; and through modular design, integration is high, and device cost is reduced greatly.

Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention is described below through specific embodiments shown in the accompanying drawings. It should be understood, however, that these descriptions are exemplary only and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0027] combine figure 1 This embodiment is described. The time synchronization device of the present invention adopts the Beidou board as the time reference, supports the work of the single Beidou satellite navigation and positioning system, and uses the Zigbee module to form a short-distance communication link within the line of sight. When the transmission distance is relatively long, GSM modules are used to form long-distance communication links. The time...
