[0048] Figure 4 This is a flowchart of the control method for a wireless indoor positioning device based on passive Internet of Things in the embodiment. Detailed Implementation

[0049] In this embodiment, the structure of the wireless indoor positioning device based on passive Internet of Things is as follows: Figure 1 As shown, it includes components such as a wireless positioning module, an energy storage module, an external signal receiving module, a signal energy conversion module, and an energy management module.

[0050] The wireless positioning module can emit Bluetooth radio frequency signals as wireless positioning signals. After receiving the Bluetooth radio frequency signals emitted by the wireless positioning module, mobile phones, tablets or dedicated positioning devices calculate the RSSII (Received Signal Strength Indication) value and perform positioning through the triangulation principle.

[0051] A module consisting of a battery and a battery management circuit can be used as an energy storage module. On the one hand, the energy storage module can accept external electrical energy input and store electrical energy, and on the other hand, it can release electrical energy. The released electrical energy can power the wireless positioning function module, enabling the wireless positioning function module to enter the working state and perform its functions.

[0052] The external signal receiving module can be integrated with the signal energy conversion module. The integrated module can include devices such as antennas and rectifier circuits. The external signal receiving module can receive external wireless signals in the form of electromagnetic waves emitted by communication base stations and other equipment, and then obtain DC power through rectification and other processing. The signal energy conversion module delivers the DC power to the energy management module. The electrical energy contained in the delivered DC power comes from the external wireless signals received by the external signal receiving module.

[0053] In this embodiment, a microprocessor and a switching transistor can be used to form an energy management module. Under the control of the microprocessor, the switching transistor controls the flow of electrical current converted by the signal energy conversion module, thereby distributing the electrical energy converted by the signal energy conversion module.

[0054] In this embodiment, the wireless indoor positioning device can be applied to... Figure 2 In the scene shown. (Refer to...) Figure 2 The system emits external wireless signals from signal sources such as 5G repeaters or 5G digital indoor distributed base stations. The wireless indoor positioning device (specifically, it can be in the form of a Bluetooth positioning base station beacon) captures the electrical energy in the external wireless signals. When the wireless indoor positioning device is working, it emits wireless positioning signals for the positioning equipment to receive and perform positioning.

[0055] In this embodiment, the external signal receiving module and signal energy conversion module in the wireless indoor positioning device can capture electrical energy from external wireless signals. The energy management module distributes and uses the electrical energy, which can overcome the limitation of a single power source powered by batteries, extend the battery life, reduce losses caused by the wireless indoor positioning device stopping working due to battery depletion, reduce the frequency of battery replacement, and save battery material costs and labor costs.

[0056] In this embodiment, when the signal energy conversion module performs the step of distributing the electrical energy converted by the signal energy conversion module, it specifically performs the following steps:

[0057] P1A. Detect the power consumption level of the wireless positioning function module;

[0058] P2A. Based on the level of electricity demand, determine the first power allocation ratio corresponding to the wireless positioning function module and the second power allocation ratio corresponding to the energy storage module;

[0059] P3A. The electrical energy converted by the signal energy conversion module is supplied to the wireless positioning function module for power supply according to the first electrical energy allocation ratio;

[0060] P4A. The electrical energy converted by the signal energy conversion module is delivered to the energy storage module for storage according to the second electrical energy allocation ratio.

[0061] Steps P1A-P4A represent one method by which the signal energy conversion module distributes the electrical energy converted by the module.

[0062] In step P1A, the signal energy conversion module detects the power demand level of the wireless positioning function module. The power demand level can be an indicator such as the rated power or maximum power of the wireless positioning function module, and its unit can be milliwatts.

[0063] In steps P2A-P4A, the signal energy conversion module can use a switching transistor to divide the electrical energy converted by the signal energy conversion module into two parts. One part accounts for the proportion of the electrical energy converted by the signal energy conversion module as the first electrical energy allocation ratio, and the other part accounts for the proportion of the electrical energy converted by the signal energy conversion module as the second electrical energy allocation ratio. That is, the sum of the first electrical energy allocation ratio and the second electrical energy allocation ratio is 1.

[0064] Specifically, when calculating the first power allocation ratio, the signal energy conversion module can set an appropriate first power allocation ratio so that the power generated by the portion of the power converted by the signal energy conversion module and allocated according to the first power allocation ratio can cover the power demand level, that is, not less than the power represented by the power demand level. After determining the first power allocation ratio, the second power allocation ratio is obtained by subtracting the first power allocation ratio from 1.

[0065] In steps P3A and P4A, after calculating the first power allocation ratio and the second power allocation ratio, the signal energy conversion module can control the conduction level of the switching transistor to allocate the power converted by the signal energy conversion module into the portion corresponding to the first power allocation ratio and the portion corresponding to the second power allocation ratio. The portion corresponding to the first power allocation ratio is sent to the wireless positioning function module for power supply, and the portion corresponding to the second power allocation ratio is sent to the energy storage module for power storage.

[0066] By executing steps P1A-P4A, the signal energy conversion module can prioritize the allocation of the converted electrical energy to power the wireless positioning function module, while the remaining electrical energy is sent to the energy storage module for storage. This ensures the electrical energy required for the wireless positioning function module to operate, reduces the number of times the energy storage module discharges, and extends the service life of the energy storage module.

[0067] In this embodiment, when the signal energy conversion module performs the step of distributing the electrical energy converted by the signal energy conversion module, it specifically performs the following steps: P1B. Detect the power demand level of the wireless positioning function module;

[0068] P2B. Obtain external power supply request information; the external power supply request information is received by the external signal receiving module.

[0069] P3B. Based on the power demand level and external power supply request information, determine the first power allocation ratio corresponding to the wireless positioning function module and the second power allocation ratio corresponding to the energy storage module;

[0070] P4B. The electrical energy obtained by the signal energy conversion module is supplied to the wireless positioning function module for power supply according to the first electrical energy allocation ratio;

[0071] P5B. The electrical energy converted by the signal energy conversion module is delivered to the energy storage module for storage according to the second electrical energy allocation ratio.

[0072] Steps P1B-P5B represent another method for the signal-energy conversion module to distribute the electrical energy converted by the module.

[0073] The principle of step P1B is the same as that of step P1A. In step P1B, the signal energy conversion module detects the power demand level of the wireless positioning function module. The power demand level can be an indicator such as the rated power or maximum power of the wireless positioning function module, and its unit can be milliwatts.

[0074] In this embodiment, it is assumed that the wireless indoor positioning device performing steps P1B-P5B is wireless indoor positioning device A, and there is another wireless indoor positioning device B. Wireless indoor positioning device B has the same structure as wireless indoor positioning device A, that is, wireless indoor positioning device B also has Figure 1 The structure is shown. Wireless indoor positioning device B can be installed in the same indoor environment as wireless indoor positioning device A, and wireless indoor positioning device B and wireless indoor positioning device A are within the communication range of wireless communication protocols (such as Bluetooth).

[0075] In this embodiment, the wireless indoor positioning device B, due to insufficient power, generates an external power supply request based on its own power shortage (which can be expressed in milliwatts), and sends the external power supply request to the outside world through its own wireless positioning function module.

[0076] In step P2B, the wireless indoor positioning device A receives the external power supply request information sent by the wireless indoor positioning device B through the external signal receiving module. By parsing the external power supply request information, it can obtain information about the power shortage of the wireless indoor positioning device B.

[0077] In step P3B, the energy management module in the wireless indoor positioning device A determines the first power allocation ratio corresponding to the wireless positioning function module and the second power allocation ratio corresponding to the energy storage module based on the power demand level and external power supply request information.

[0078] In steps P3B-P5B, the signal energy conversion module can use a switching transistor to divide the electrical energy converted by the signal energy conversion module into two parts. One part accounts for the proportion of the electrical energy converted by the signal energy conversion module as the first electrical energy allocation ratio, and the other part accounts for the proportion of the electrical energy converted by the signal energy conversion module as the second electrical energy allocation ratio. That is, the sum of the first electrical energy allocation ratio and the second electrical energy allocation ratio is 1.

[0079] Specifically, when calculating the first power allocation ratio, the signal energy conversion module can set an appropriate first power allocation ratio so that the power generated by the portion of the power converted by the signal energy conversion module and allocated according to the first power allocation ratio can cover the sum of the power demand level and the power represented by the external power supply request information, that is, not less than the sum of the power demand level and the power represented by the external power supply request information. After determining the first power allocation ratio, the second power allocation ratio is obtained by subtracting the first power allocation ratio from 1.

[0080] In steps P4B and P5B, after calculating the first and second power allocation ratios, the signal energy conversion module can control the conduction level of the switching transistor to allocate the power obtained by the signal energy conversion module into the portion corresponding to the first power allocation ratio and the portion corresponding to the second power allocation ratio. The portion corresponding to the first power allocation ratio is sent to the wireless positioning function module for power supply, and the portion corresponding to the second power allocation ratio is sent to the energy storage module for power storage.

[0081] By executing steps P1B-P5B, the signal energy conversion module in wireless indoor positioning device A can prioritize allocating the converted electrical energy to power its own wireless positioning function module, while the remaining electrical energy is stored in its own energy storage module. The electrical energy allocated to the wireless positioning function module covers the sum of the power demand level and the power indicated by the external power supply request information. In other words, besides meeting the operational needs of the wireless positioning function module, the remaining electrical energy can be transmitted by the wireless positioning function module of wireless indoor positioning device A. The transmission form can be a wireless positioning signal. The wireless positioning signal transmitted by wireless indoor positioning device A is an external wireless signal relative to wireless indoor positioning device B. Wireless indoor positioning device B can perform steps similar to P1A-P4A to obtain electrical energy. Therefore, by executing steps P1B-P5B, one of the wireless indoor positioning devices (such as wireless indoor positioning device A) can respond to the request of another wireless indoor positioning device (such as wireless indoor positioning device B) and allocate power to the other wireless indoor positioning device, thereby realizing power distribution across wireless indoor positioning devices. This can effectively address the problem that when multiple wireless indoor positioning devices are installed, some wireless indoor positioning devices may not be well covered by signal sources such as 5G repeaters and thus cannot obtain power transmitted by 5G repeaters. It can ensure the power required for the operation of the wireless positioning function module when multiple wireless indoor positioning devices are installed, reduce the number of discharges of the energy storage module, and extend the service life of the energy storage module.

[0082] In this embodiment, taking a single wireless indoor positioning device (such as wireless indoor positioning device B) as an example, the energy management module of wireless indoor positioning device B also performs the following steps:

[0083] P6. Detect the power consumption level of the wireless positioning function module;

[0084] P7. Detect the initial power supply capability level of the energy storage module;

[0085] P8. Detect the second power supply capability level of the signal energy conversion module;

[0086] P9. Determine the external power supply demand level based on the power demand level, the primary power supply capacity level, and the secondary power supply capacity level;

[0087] P10. Generate external power supply request information based on the level of external power demand;

[0088] P11. Send the external power supply request information to the wireless positioning function module;

[0089] P12. Trigger the wireless positioning function module to send an external power supply request message.

[0090] In step P6, the energy management module detects the power demand level of the wireless positioning function module. The power demand level can be represented by indicators such as the rated power or average power (in milliwatts) of the wireless positioning function module.

[0091] In step P7, the energy management module detects the first power supply capability level of the energy storage module. Specifically, the energy storage module can detect the battery voltage, obtain the remaining power through the power supply curve, and then look up the maximum discharge power or average discharge power of the battery in the table as the first power supply capability level corresponding to the energy storage module.

[0092] In step P8, the energy management module detects the second power supply capability level of the signal energy conversion module. Specifically, the energy conversion module can detect the signal strength it receives and calculate or query the corresponding signal power and other indicators as the second power supply capability level of the energy conversion module.

[0093] The power demand level obtained in step P6 represents the power required for the internal module of the wireless indoor positioning device B to operate. The sum of the first power supply capability level and the second power supply capability level obtained in steps P7-P8 represents the power supply capability of the internal module of the wireless indoor positioning device B, such as the maximum power it can handle. Therefore, in step P9, the difference between the sum of the first power supply capability level and the second power supply capability level and the power demand level represents the power shortage that exists when the wireless indoor positioning device B relies solely on its internal module for power supply. This indicator can be used as the external power supply demand level.

[0094] In step P10, the energy management module in the wireless indoor positioning device B generates external power supply request information based on the external power supply demand level. Specifically, the energy management module in the wireless indoor positioning device B can package the external power supply demand level using a specific format to obtain the external power supply request information.

[0095] In steps P11-P12, the energy management module in the wireless indoor positioning device B sends the external power supply request information to the wireless positioning function module, triggering the wireless positioning function module to send the external power supply request information.

[0096] After wireless indoor positioning device B completes steps P6-P12, refer to Figure 3 If the external power supply request information sent by the wireless indoor positioning device B is received by other wireless indoor positioning devices (such as wireless indoor positioning device A), then wireless indoor positioning device A can execute steps P1B-P5B, and wireless indoor positioning device A sends a stronger wireless positioning signal to meet the needs of wireless indoor positioning device B.

[0098] S1. Control the wireless positioning function module to send out wireless positioning signals;

[0101] S4. The control signal energy conversion module acquires external wireless signals and converts the energy of the external wireless signals into electrical energy;

[0102] S5. The control energy management module distributes the electrical energy converted by the signal energy conversion module.
