Please refer to FIG. 1 and FIG. 2, wherein FIG. 1 shows an exploded schematic diagram of a tracking and positioning wearable device 100 according to an embodiment of the present invention, and FIG. 2 shows a tracking and positioning wearable device 100 of FIG. 1. System block diagram. The signal of the tracking and positioning wearable device 100 is connected to a cloud C1 and used to receive a positioning request message from the cloud C1. The tracking and positioning wearable device 100 includes a housing 200, an operating system 300, a battery 400 and an energy supplement. Agency 500.

The operating system 300 is disposed in the housing 200 and includes a communication positioning module 310 and a control module 320. The communication positioning module 310 has a positioning function to capture position information, and the communication positioning module 310 is used to receive a positioning request. Message and sending location information, the control module 320 signal is connected to the communication positioning module 310. The battery 400 is disposed in the casing 200. The battery 400 provides a main power to the operating system 300 and has a voltage. The energy supplementing mechanism 500 is disposed in the casing 200 and is electrically connected to the battery 400. The energy supplementing mechanism 500 provides a supplementary power supply. The battery 400 is charged. When the communication positioning module 310 receives a positioning request message, the control module 320 causes the communication positioning module 310 to start a positioning function and transmit position information to the cloud C1.

In this way, the communication positioning module 310 can provide location information according to the positioning request message, so that the positioning function can be used to save power consumption without turning on the power at the same time. At the same time, the energy supplementing mechanism 500 can supplement the power of the battery 400 Power, and let the battery 400 restore power to prolong the use time. Details of the tracking and positioning wearable device 100 will be described in more detail later.

The housing 200 has an upper cover and a lower cover that cooperate with each other to accommodate a space for the operating system 300, the battery 400, and the energy supply mechanism 500. The housing 200 is made of a rigid material and has anti-collision and protection functions. An oil seal can be added to make the housing 200 liquid-tight to increase the waterproof performance. In other embodiments, hypoallergenic silicone can be used at the skin-contacting part of the lower cover to provide users with more comfortable wearing.

The battery 400 is a rechargeable lithium battery. The energy supply mechanism 500 may include a solar battery 510 and a charging module 520. The charging module 520 is electrically connected to the solar battery 510 and the battery 400. The solar cell 510 may be a flexible solar cell or a CIGS thin-film solar cell, which can convert solar energy into electrical energy. The electrical energy of the solar cell 510 is boosted by the charging module 520 and converted into supplementary power for charging the battery 400, and the supplementation can be maintained. The power of the battery 400 enables the tracking and positioning of the wearable device 100 without additional charging equipment. In other embodiments, the energy supplementing mechanism 500 may be a micro-electro-mechanical mechanism using wind power generation, or a mechanism using mechanical energy to convert electrical energy, and is not limited thereto.

The communication positioning module 310 of the operating system 300 may include a data sending unit 311 and a message receiving unit 312. The message receiving unit 312 is used to receive a positioning request message, and the data sending unit 311 is used to send location information. Therefore, when the voltage of the battery 400 is less than a low critical value, the control module 320 causes the communication positioning module 310 to turn off the positioning function to enter a master-slave mode. In the master-slave mode, the message receiving unit 312 is deactivated every other sleep time. Startup confirmation Whether a positioning request message is received. If a positioning request signal is received, the positioning function is activated and the data sending unit 311 provides location information to the cloud C1.

Since the voltage of the battery 400 decreases with the power consumption, the control module 320 can adjust the use status of the operating system 300 according to the voltage of the battery 400, which can reduce the power consumption to extend the use time of the tracking and positioning wearable device 100. Therefore, when the voltage of the battery 400 is lower than a low threshold value, turning off the positioning function can reduce the power consumption, and the supplementary power provided by the energy supplementing mechanism 500 can be fully charged, and the battery 400 will be charged to a certain level. After the voltage level, the positioning function can automatically locate according to the schedule time.

In the master-slave mode, the positioning function is turned off for a long time, and the message receiving unit 312 is turned on periodically to confirm whether a positioning request signal is received. To put it in detail, the sleep time can be set to 150 minutes, and the message receiving unit 312 will be turned on every 150 minutes. Therefore, if someone wants to confirm the user's position in the master-slave mode, it can send a positioning request signal through the cloud C1. Then, when the message receiving unit 312 is turned on to confirm the status, once receiving a positioning request signal, the control module 320 turns on the positioning function of the communication positioning module 310 to obtain the position information, and causes the data sending unit 311 to send the position information to Cloud C1 allows other people to obtain the user's location and can perform immediate rescue.

In more detail, the network positioning unit 313 can receive LTE (Long Term Evolution), WCDMA (Wideband Code Division Multiple Access), HSUPA (High Speed Uplink Packet Access), HSDPA (High-Speed Downlink Packet Access), or CDMA (Code Division Multiple Access) signals have a wireless network connection function.

Through the above-mentioned network positioning unit 313 and satellite positioning unit 314, the communication positioning module 310 can be provided with a positioning function. In general urban areas, there are a large number of base stations, so that the positioning of the network positioning unit 313 can be performed. It is more accurate, and the power consumption of the positioning function performed by the network positioning unit 313 is low. Therefore, the network positioning unit 313 can be used for positioning. However, in a small number of suburban base stations, the positioning accuracy of the network positioning unit 313 is low, so at this time, the satellite positioning unit 314 may be used to perform the positioning function.

In other embodiments, the communication positioning module 310 may further include a voice call function, and a voice call may be made for the fire rescue unit to use enhanced call-for-number technology (Enhance-911) to obtain the tracking and positioning of the wearable device 100. Location information.

It should be particularly noted here that the operating system 300 in this embodiment uses a SIM5310 chip to connect the antenna to achieve all the above functions (including the call function). In other embodiments, other similar functions can also be used. The chip, or a combination of multiple components to achieve the functions and objectives of the operating system 300 in the present invention, includes the above but is not limited thereto.

Please refer to FIG. 3, and please also refer to FIG. 2, wherein FIG. 3 illustrates a flowchart of steps of a power management method 600 according to another embodiment of the present invention. The power management method 600 includes steps 610 and 620.

In step 610, a basic data obtaining operation is performed, in which the control module 320 obtains the voltage (BV) of the battery 400.

In step 620, a mode selection operation is performed. The control module 320 selects the operating mode of the communication positioning module 310 according to the voltage. When the voltage is lower than a low threshold value, the control module 320 causes the communication positioning module 310 to enter a master-slave. Mode, in the master-slave mode, the control module 320 activates the communication positioning module 310 at a long sleep time to confirm whether it receives a positioning request message from the cloud C1, thereby determining whether to enable the positioning function of the communication positioning module 310 Capture location information and send location information to Cloud C1.

In this way, in the mode selection operation, the control module 320 can select the operation mode of the communication positioning module 310, so that the tracking and positioning wearable device 100 can still perform master-slave positioning while saving energy and charging as much as possible. C1 has a function of updating the location information and can increase the usage time of tracking and positioning the wearable device 100. Details of the power management method 600 will be described later.

In more detail, in step 610, the control module 320 can be electrically connected to the battery 400 to obtain the voltage of the battery 400, and the control module 320 can also obtain a charging power (PC) of the energy supplementing institution 500 and the operating system 300. A working power consumption (PW) and a sleep power consumption (PS). The charging power is calculated by the current of the supplementary power provided by the energy supplementing agency 500. The working power consumption refers to the power consumption when the positioning function is turned on in the communication positioning module 310, and the sleep power consumption refers to the power consumption in the communication positioning module 310. Power consumption when positioning function is off.

In step 620, the control module 320 selects the operation mode of the communication positioning module 310 according to the voltage. Since the battery 400 in this embodiment is a lithium battery, the high threshold value of the voltage can be set to 3.8 volts, and The low critical value can be set to 3.6 volts, so that when the voltage is greater than 3.8 volts, between 3.6-3.8 volts, and the voltage is less than 3.6 volts, the communication positioning module 310 will operate in different operating modes.

In detail, when the voltage is less than a low critical value (3.6 volts), the power consumption of the operating system 300 needs to be reduced to avoid power loss. Therefore, as described above, the control module 320 causes the communication positioning module 310 to enter the master-slave mode. At this time, the positioning function will be turned off for a long time. Only the message receiving unit 312 will be turned on periodically to confirm whether a positioning request signal is received. However, after receiving the positioning request signal, the control module 320 turns on the positioning function of the communication positioning module 310 to obtain the position information, and causes the data sending unit 311 to send the position information to the cloud C1.

Conversely, when the voltage is higher than the high threshold (3.8 volts), it means that the battery 400 has sufficient power, and the control module 320 starts to determine the voltage every other sleep time. The bit function enables the communication positioning module 310 to operate in a normal mode, wherein the sleep time is shorter than the long sleep time. In this normal mode, the sleep time can be set to 90 minutes, so when 90 minutes arrive, there is no need to confirm the message receiving unit 312. Instead, the positioning function is directly turned on to obtain the location information, and the location information is transmitted to the cloud C1. The location information received by C1 can be updated regularly.

When the voltage is between the high critical value and the low critical value (3.6-3.8 volts), the control module 320 can extend the rest time to obtain a long rest time, and the long rest time is not greater than the long sleep time. To elaborate, when the voltage is between the high and low thresholds, it means that the power starts to fall. It may be caused by the power consumption being higher than the charge. Therefore, the rest time will be increased to reduce the system's long-term consumption. For example, First increase the rest time by a basic time to obtain a long rest time. The control module 320 will use this long rest time to pre-calculate the total power consumption of the operating system 300. This total power consumption is power consumption x long rest time + work Consumption power x the time when the positioning function is turned on. In addition, the control module 320 calculates the charging amount based on the charging power, so the charging amount is the charging power x (long rest time + positioning function on time). After the calculation is completed, the control module 320 compares the charging amount with the total power consumption. If the calculation result is that the charging amount during this period will be higher than the total power consumption, it will start to operate with this long rest time, which means that the control module The group 320 automatically wakes up the positioning function and transmits position information every this long rest time until the voltage is higher than a high threshold and then returns to the normal mode. Conversely, if the total power consumption is still higher than the charge amount, the long rest time will be lengthened (the base time will be longer) and another new long rest time will be calculated. The long rest time can only be equivalent to the long sleep time. Although the long rest time at this time is equivalent to the long sleep time, it is different from the master-slave mode in that the control module 320 rests every such long time. It will automatically wake up the positioning function to actuate and send position information, instead of receiving the positioning request message as a prerequisite as in the master-slave mode.

Please refer to FIG. 4, and refer to FIG. 2 and FIG. 3 together, where FIG. 4 is a block flowchart of a power management method 600 according to another embodiment of the present invention. From the block flow chart, it can be known that when the operating system 300 starts to operate, the operation step 610 is started to perform the basic data acquisition operation. The control module 320 will obtain the current voltage (BV) of the battery 400 and the current time charge. The power (PC), and the work power consumption (PW) and sleep power consumption (PS) budgeted in advance are loaded. Then, operation step 620 is started to perform a mode selection operation, and the control module 320 selects an operating mode according to the voltage.

When the voltage is greater than 3.8 volts, the communication positioning module 310 operates in the normal mode, and the control module 320 activates the positioning function for active positioning and returns position information every sleep time; when the voltage is between 3.6-3.8 volts, let the sleep time first Add 10 minutes (basic time) and start to estimate the power consumption and charging amount based on basic data until the power consumption is greater than the charging amount or the long rest time is equal to the long sleep time, and then start to let the control module 320 start the positioning function every long rest time. Perform proactive positioning and return location information.

When the voltage is less than 3.6 volts, the control module 320 stops the positioning function of the communication positioning module 310, and confirms the positioning request message every long sleep time. If there is a positioning request message, the positioning function is activated to perform master-slave positioning and return position information.

It should be particularly noted here that active positioning does not need to receive the positioning request message as a prerequisite for starting the positioning function, and master-slave positioning needs to receive the positioning request message as a prerequisite for starting the positioning function.

Please refer to FIG. 3 again, the power management method 600 further includes a super step 630. In step 630, a positioning selection operation is performed. The communication positioning module 310 includes a network positioning unit 313 and a satellite positioning unit 314. The signal of the network positioning unit 313 is connected to at least one network base station M1. When the signal of the network positioning unit 313 is When the number of connected network base stations M1 is less than a preset value or when high-precision positioning is required, the positioning function is provided by the satellite positioning unit 314. In the case of non-high-precision positioning, the communication positioning module 310 can be provided with the network positioning unit 313 to provide positioning functions by default; and the number of network base stations M1 connected to the signal of the network positioning unit 313 is less than the preset value (For example, two) or when high-precision positioning is required, the positioning function is provided by the satellite positioning unit 314 to avoid power consumption.

In addition, if it is poor weather, buildings, tunnels, or satellite signals, regardless of whether the number of network base stations M1 connected to the network positioning unit 313 is greater than or equal to the preset value, the network positioning unit 313 provides positioning. Function, which can also prevent the satellite positioning unit 314 from searching for satellite signals and consuming power. Or when the battery voltage is above a high threshold and the satellite signals are not obscured and high-precision positioning coordinates are desired, you can use the positioning request message or log in to the management platform remotely to instruct the tracking wearable device 100 to start the satellite The positioning unit 314 obtains high-precision position information.

Since the communication positioning module 310 includes a network positioning unit 313 and a satellite positioning unit 314, the network positioning unit 313 may be provided by default. It provides positioning function, so the power consumption of the work budgeted in advance can be calculated based on the power consumption of the network positioning unit 313 during positioning, but it is not limited to this.
