[0027] In some embodiments, reference Figure 1 and Figure 2 The portable wireless relay device 100 includes: a backpack 101 and a wireless relay device arranged in the backpack 101; a fixing plate 114 is provided on the inner side of the backpack, and the wireless relay device includes a wireless transceiver module 109, a control module, a signal antenna 103 and a power module; the wireless transceiver module 109, the control module and the power module are fixedly connected to the fixing plate 114, and the signal antenna 103 is arranged on the outside of the backpack 101 and fixedly connected to the outside of the backpack 101; the wireless transceiver module 109 and the control module are electrically connected to the power module respectively, and the wireless transceiver module 109 is communicatively connected to the control module and the signal antenna 103 respectively; the portable wireless relay device also includes a status indicator light 102 and an external interface 108, the status indicator light 102 and the external interface 108 are provided on the backpack 101, the status indicator light 102 is electrically connected to the control module, and the external interface 108 is communicatively connected to the control module.

[0028] In some embodiments, the backpack 101 is dustproof and waterproof. A shoulder strap 113 is provided at each end of the backpack 101. One end of the shoulder strap 113 is connected to the backpack 101, and the other end is provided with a buckle 112. The two buckles 112 can be fastened together to secure the backpack 101 to a person or other object. Because the core components of the entire device are placed in the waterproof and dustproof backpack 101, the portable wireless relay device can operate in various complex conditions (such as high humidity and dusty environments), is easy for technicians to carry, and meets the information transmission needs of different working conditions.

[0029] In some implementations, the control module includes a controller 104 and a memory 110 . The wireless transceiver module 109 is in communication with the controller 104 . The controller 104 and the wireless transceiver module 109 support the same wireless communication protocol. The memory 110 is in communication with the controller 104 .

[0030] In some embodiments, the wireless communication protocol includes at least one of LoRa, ZigBee, NB-IOT, Bluetooth, and Wi-Fi. For example, when the wireless communication protocol is LoRa, the wireless transceiver module 109 is a wireless transceiver that supports the LoRa protocol, and the controller 104 is a microcontroller unit (MCU) capable of processing the LoRa protocol.

[0031] In some embodiments, reference Figure 1 and Figure 2 The portable wireless relay device also includes: a photovoltaic charging panel 105 and a first battery 106; the first battery 106 is arranged in the backpack 101, fixedly connected to the fixing plate 114, and electrically connected to the power module; the photovoltaic charging panel 105 is electrically connected to the first battery 106, and the photovoltaic charging panel 105 is arranged on the outside of the backpack 101 and is detachably connected to the outside of the backpack 101.

[0032] In some embodiments, the photovoltaic charging panel 105 can be a monocrystalline silicon photovoltaic panel, a polycrystalline silicon photovoltaic panel, a thin-film photovoltaic panel, or an organic photovoltaic panel. The first battery can be a photovoltaic battery, such as a maintenance-free lead-acid battery, a conventional lead-acid battery, a gel battery, or an alkaline nickel-cadmium battery. The types of the photovoltaic charging panel and the first battery are not limited in this application.

[0033] In some embodiments, the power module includes: a second battery 107 and a power management device 111, the power management device 11 is connected to the first battery 106 and the second battery 107 respectively, the second battery 107 is connected to the external interface 108 through the power management device 111, and the power management device 111 is used to electrically connect the first battery 106 or the second battery 107 to the wireless transceiver module 109 and the control module.

[0034] In some embodiments, when outdoor lighting conditions are sufficient, the power management device 111 preferentially connects the first battery 106 to the control module, using the first battery to power the entire device, thereby maximizing the device's operating time. When the first battery 106 is insufficient to maintain device operation, the second battery 107 is electrically connected to the control module, powering the device. This achieves more efficient power management, maximizing device operating time, and providing greater convenience for working in complex environments.

[0035] In some embodiments, the external interface 108 may integrate a power switch, a data transmission interface, and a power supply interface.

The power supply interface is used to charge the second battery 107, and its interface form is not limited.

[0036] Taking the wireless communication protocol LoRa as an example, when the portable wireless relay device is powered on, the wireless transceiver module 109 receives data information via the signal antenna 103 according to pre-configured parameters. After data processing by the controller 104, the data information is transmitted again via the wireless transceiver module 109 to other remote devices or stored in the memory 110. In some embodiments, the portable wireless relay device further includes an operating component. The operating component is connected to the control module via an external interface; alternatively, the operating component is connected to the control module via the wireless transceiver module.

[0037] For example, a staff member can configure the controller 104 and the wireless transceiver module 109 through the operating components. For example, the staff member can configure whether to store the data received by the wireless transceiver module 109 in the memory 110 or send it to the target device. When the received data is sent to the target device, the reception parameters of the target device can also be configured. The specific configuration functions and configuration interface are not limited in this application.

[0038] Here, the operation flow of the portable wireless relay device 100 will be described.

[0039] First, turn on the portable wireless relay device's power switch to confirm that the power is on and all modules are operating successfully. Once the device is powered on and operating normally, the power management device activates the first battery to maintain device operation if it detects sufficient charge in the first battery or if energy is being input from the photovoltaic panel. If the first battery's charge is low and the energy input from the photovoltaic panel is below a preset threshold, the first battery is activated to maintain device operation.

[0040] Then, when the device is running stably, it is connected to the target device (such as a device that receives data or a device that sends data) through the wireless transceiver module.

[0041] Finally, after successfully connecting, bring the portable wireless relay device to the work site and transmit and receive data using the wireless transceiver module. During this process, you can export and receive data through an external interface. For example, you can import and transmit data from the work site through an external interface. When finished, turn off the device.

This device can increase the coverage of IoT device signals, improve the quality of communication signals between IoT devices, and meet the application needs of specific industries. In particular, it can support IoT communications in areas where large coverage is required and infrastructure is relatively scarce.

[0044] It should be noted that in this application, circuits, controllers, and other contents that can be undoubtedly determined by those skilled in the art are not described in detail. Those skilled in the art can undoubtedly derive specific implementation plans based on the contents of this application.
