Embodiment Construction
[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0018] This embodiment provides a low-power control method for a Beidou satellite communication and positioning device, and the low-power design can make its standby time up to about 48 hours.
[0019] Such as figure 1 As shown, the Beidou satellite communication positioning device includes: Beidou RDSS antenna, Beidou RDSS communication module, Beidou RNSS antenna, Beidou RNSS positioning and timing module, control module, display module, input module and through the power management module for all the above modules (ie Power supply for all modules except Beidou RDSS antenna and Beidou RNSS antenna). Among them, the Beidou RDSS communication module, the Beidou RNSS positioning and timing module, the display module (that is, the display screen), the input module (keyboard) and the power management module are respectively connected to the cont...

The invention discloses a low power consumption control method of a Beidou satellite communication positioning device, which effectively prolongs the standby and working time of the Beidou satellite communication positioning device through the design of low power consumption. The method detects the working mode of the Beidou satellite communication positioning device, and sets the working mode of the Beidou RDSS communication module to the intermittent working mode in the footprint mode, which reduces the power consumption of the Beidou RDSS communication module to transmit RDSS; and according to the Beidou satellite The motion state of the communication positioning device adjusts the communication frequency of the Beidou RDSS communication module, which can effectively prolong the standby and working time of the Beidou satellite communication positioning device.
Description
technical field [0001] The invention relates to a low power consumption control method, in particular to a low power consumption control method of a Beidou satellite communication positioning device, and belongs to the technical field of the Beidou satellite navigation communication system. [0002] technical background [0003] In the civilian ICD file provided by the Beidou Navigation System, the public service signal is the B1 frequency point signal. At present, there are 14 Beidou satellites working in the service area over the Chinese mainland, providing free positioning, speed measurement, and timing services. The timing accuracy is nanosecond level, and the positioning accuracy is 10 meters. The Beidou satellite system also has short-message communication functions and has been widely used in disaster prevention and relief, hydrology, meteorology, oceanography, forestry and other fields. [0004] However, in view of the large power consumption of the current handheld ...
