Efficiency and chance of success in search and rescue.

Please refer to FIG. 1, which is a schematic diagram of a preferred embodiment of the novel positioning and tracking device.

The positioning and tracking device 100 includes a power module 10, a first positioning module 20, a second positioning module 30, and a control module 40. The power supply module 10 is electrically connected to the first positioning module 20, the second positioning module 30, and the control module 40. The power supply module 10 is used to perform the positioning and tracking device 100. powered by. The first positioning module 20 is configured to output a first positioning signal, and the second positioning module 30 is configured to output a second positioning signal. The power consumption of the first positioning module 20 is preferably greater than the power consumption of the second positioning module 30.

In one embodiment, the first positioning module 20 is preferably a GPS positioning module, and the second positioning module 30 is preferably a LORA positioning module. LORA positioning module is a positioning module developed based on LORA wireless communication technology. It has the advantages of low power consumption and strong anti-interference.

The control module 40 is electrically connected to the first positioning module 20 and the second positioning module 30, and is configured to determine whether a rescue trigger signal is received, and to control the rescue trigger signal when the rescue trigger signal is received. The first positioning module 20 sends a first positioning signal for help.

In one embodiment, the rescue trigger signal may be manually triggered or automatically detected when the positioning and tracking device 100 is currently in a distressed environment. For example, set the distress environment to the water state. As shown in FIG. 2, the positioning and tracking device 100 further includes a rescue button 50 and a detection module 60. When the rescue button 50 is pressed, a rescue trigger signal is generated, and the control module 40 can receive To the rescue trigger signal and control the first positioning module 20 to send a first positioning signal. The detection module 60 is configured to detect and determine whether the current environment information of the positioning and tracking device 100 satisfies a preset condition. When the current environment of the positioning and tracking device 100 satisfies the preset condition, the detection The detection module 60 generates the rescue trigger signal. For example, the positioning and tracking device 100 is disposed on a life jacket. When the wearer wears a life jacket with the positioning and tracking device 100, if the wearer falls into the water, the detection module 60 It can be detected that the positioning and tracking device 100 is in a falling water environment, and the rescue trigger signal is generated. In order to detect the falling water environment, the detection module 60 may include a water immersion sensor.

It can be understood that the positioning and tracking device 100 may not be provided with the rescue button 50 and the detection module 60 at the same time. In other embodiments of the present invention, the positioning and tracking device 100 may be provided with a rescue button 50 without a detection module 60, or a detection module 60 without a rescue button 50.

In an embodiment, the detection module 60 is further configured to detect and determine whether the physiological characteristic information of the current user satisfies a preset physiological characteristic, and when the physiological characteristic information of the current user satisfies the preset physiological characteristic When it is characterized, the detection module 60 generates the rescue trigger signal. The physiological characteristics may be information such as the user's heartbeat, body temperature, and blood oxygen. When the detection module 60 detects that the current user's heartbeat, body temperature, and blood oxygen are in an abnormal state, it indicates that the user is in a distressed state, so The detection module 60 generates the rescue trigger signal. In order to detect heartbeat, body temperature, blood oxygen and other information, the detection module 60 may include a millimeter wave sensor, a body temperature sensor, and a blood oxygen sensor. It is understood that the physiological characteristic information of the current user can also be detected by the detection module 60, and the control module is used to determine whether the physiological characteristic information of the current user satisfies a preset physiological characteristic.

In one embodiment, the power module 10 can be charged by receiving solar energy, thereby improving the endurance of the positioning and tracking device 100. For example, the power module 10 includes a battery 110 and a charging unit 112 (as shown in FIG. 2). The charging unit 112 can receive solar energy and generate a charging current to charge the battery 110.

Because the effective range of the LORA positioning module is generally within 15-20 kilometers, but the power consumption is low, when the search and rescue personnel are far away from the victim, they will not be able to receive rescue signals. The GPS positioning module has a wide effective range, but High power consumption, in order to improve the success rate of rescue. The control module 40 is further configured to determine whether the power of the power module 10 is lower than a preset power. When the power of the power module is lower than the preset power, the control module 40 also controls The first positioning module 20 enters a sleep mode, and controls the second positioning module 30 to send a second positioning signal. Since the second positioning module 30 is a LORA positioning module, the power consumption is low, and the rescue success rate can be further improved.

In one embodiment, because the GPS positioning module consumes a large amount of power and the charging effect of the power module 10 will fluctuate greatly with the uncertainty of the light, in order to improve the success of search and rescue, ensure that the distress positioning signal is maintained as much as possible For a long time, when the power of the power module 10 is lower than the preset power, the control module 40 controls the first positioning module 20 to enter the sleep mode and stops sending the first positioning signal. At this time, since the power of the power module 10 is lower than the preset power, only the second positioning module 30 continues to send the second positioning signal. When the power module 10 is charged by receiving solar energy so that the current power is greater than the preset power, the control module 40 may control the first positioning module 20 to send a first positioning signal again.

In one embodiment, the preset power can be set according to actual use requirements, such as setting the preset power to 60% of the total power, and when the power of the power module 10 is not less than 60%, the The control module 40 also controls the first positioning module 20 to send a first positioning signal and the second positioning module 30 to send a second positioning signal. When the power of the power module 10 is lower than 60%, The control module 40 only controls the second positioning module 30 to send a second positioning signal.

In one embodiment, when the power of the power module 10 is lower than the preset power, the control module 40 may control the first positioning mode if the rescued person has just triggered to generate the rescue trigger signal. The group 20 sends a first positioning signal of a preset duration, and then controls the first positioning module 20 to enter a sleep mode after the transmission is completed, so as to prevent the GPS signal from being sent out immediately when the victim suffers, which affects search and rescue efficiency. For example, when the power of the power module 10 is lower than the preset power, the control module 40 determines whether the receiving time of the rescue trigger signal is shorter than a preset time (for example, the preset time is 2s) ) To determine whether the victim has just triggered the rescue trigger signal; when the reception time of the rescue trigger signal is less than the preset time, the control module 40 controls the first positioning module 20 to send a preset A long (such as 10s) first positioning signal; when the reception time of the rescue trigger signal is not less than the preset time, indicating that the rescue trigger signal was not generated just after the trigger, the control module 40 controls the first The positioning module 20 enters the sleep mode.

In one embodiment, if the rescue trigger signal is manually triggered by the rescue button 50, if the power of the power module 10 at this time is lower than the preset electricity, it can be set when the victim is using the rescue button 50 When the rescue trigger signal is triggered once, the control module 40 can control the first positioning module 20 to send a first positioning signal once.

For example, when a user carrying the positioning and tracking device 100 is killed, the control module 40 may control the second positioning module 30 to send a second positioning signal and control the first positioning module according to a rescue trigger signal. The group 20 sends a first positioning signal of a preset duration to determine the location of the victim. At this time, if the power of the power module 10 is low, only the second positioning module 30 is continuously sent the second positioning signal. Searchers can search for the victim according to the RSSI of the second positioning signal that is continuously sent out, avoiding relying solely on GPS signals for search and rescue, and GPS positioning will have positioning errors and power consumption problems. If the victim is constantly moving, GPS will be more difficult Precise positioning.
