Problems solved by technology

[0003] At present, the handheld satellite positioning terminal on the market, when uninterrupted positioning information is required, its working mode is continuous positioning, so that the satellite positioning module always works, because the satellite positioning module consumes a lot of power during positioning, so it will seriously affect the handheld terminal. Normal working hours of satellite positioning terminals

Embodiment 1

[0039] The invention provides a power-saving satellite positioning terminal, such as figure 1 As shown, it includes:

[0040] Positioning unit 1: used to locate its own position, its working state includes positioning mode and power saving mode;

[0041] Timing unit 2: Set the time value of the positioning unit in different working states;

[0042] The positioning unit 1 switches back and forth between the positioning mode and the power saving mode, specifically:

[0043] When the positioning unit 1 is in the positioning mode, it locates its own position; and when the positioning is successful or the set time ends, the positioning unit 1 switches from the positioning mode to the power saving mode;

[0044] When the positioning unit 1 is in the power saving mode, it stops positioning; and when the set time is over, the positioning unit 1 switches from the power saving mode to the positioning mode.

[0045] In this embodiment, the positioning unit 1 includes a satellite positioning mod...

Embodiment 2

[0052] This embodiment provides a power-saving satellite positioning method, which includes the following steps:

[0053] 1) Provide a positioning unit: used to locate its own position, its working state includes positioning mode and power saving mode; and a certain time unit: set the time value of the positioning unit in different working states;

[0054] 2) Start the positioning unit to enter the positioning mode to start positioning, and start the timing unit at the same time;

[0055] 3) The positioning unit is successfully positioned or the positioning mode time of the timing unit is up, the positioning unit switches from the positioning mode to the power saving mode;

[0056] 4) After the positioning unit enters the power saving mode, the positioning unit stops positioning. When the power saving mode setting time of the timing unit expires, the positioning unit switches from the power saving mode to the positioning mode, and the positioning mode time is less than the power saving...

Embodiment 3

[0067] In this example, the timing time of the positioning timer is set to the time required to obtain positioning when the satellite positioning module is cold-started (usually around 40 seconds). In this embodiment, the positioning timer is recorded as the T1 timer; The timing time of the electrical timer is set to T4, and T4 is the smaller of T2 and T3, namely: T4=MIN(T2, T3). Among them, T2 is the maximum time (usually tens of minutes) for the satellite positioning module to maintain the module in the hot start state after successful positioning, and T3 is the time interval for the satellite positioning terminal to provide positioning information (usually a few minutes to tens of minutes). In this embodiment, the power saving timer is denoted as T4 timer.

[0068] In the terminal control platform, first execute the satellite positioning module startup program such as figure 2 As shown, S11-S12: start to start the satellite positioning module to make it enter the satellite po...

Abstract

The invention provides an electricity-saving satellite positioning method. The electricity-saving satellite positioning method comprises the following steps that (1) a positioning unit and a timing unit are provided; (2) the positioning unit is started to enter a positioning mode, so that positioning is started, and the timing unit is started; (3) when the positioning unit successfully conducts positioning or the time of the positioning mode of the timing unit is up, the positioning unit is switched to an electricity-saving mode from the positioning mode; (4) after the positioning unit enters the electricity-saving mode, the positioning unit stops positioning, and when the set time of the electrify-saving mode of the timing unit is up, the positioning unit is switched to the positioning mode from the electricity-saving mode, wherein the time of the positioning mode is shorter than the set time of the electricity-saving mode; (5) after the positioning unit enters the positioning mode, the step (3) is executed again. By the adoption of the electricity-saving satellite positioning method, a provided satellite positioning module works in the positioning state within a short time, and most of the time, the satellite positioning module works in the electricity-saving state; in addition, switching between the electricity-saving mode and the positioning mode is controlled through interrupt signals, control is orderly and not prone to errors, and long-term periodical positioning is facilitated.

Description

technical field [0001] The invention relates to satellite positioning technology, in particular to a power-saving positioning method for a satellite positioning terminal and a power-saving satellite positioning terminal. Background technique [0002] Usually, the power consumption of a satellite positioning module during positioning is hundreds or even thousands of times that of the module in power-saving mode. For example, the average current of a Beidou module is 60mA, while the average current in power-saving mode is 20uA. The power consumption differs by a factor of 3000. [0003] At present, the handheld satellite positioning terminal on the market, when uninterrupted positioning information is required, its working mode is continuous positioning, so that the satellite positioning module always works, because the satellite positioning module consumes a lot of power during positioning, so it will seriously affect the handheld terminal. The normal working hours of the s...
