[0035] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0036] like Figure 1 As shown, a wireless broadcast and walkie-talkie system with GPS positioning is provided, aiming to address the shortcomings of existing broadcast and walkie-talkie systems in complex environments such as large-scale event venues, natural disaster emergency command, and urban security. Traditional broadcast systems typically have limited coverage and cannot be effectively integrated with walkie-talkie systems; while traditional walkie-talkie systems have strong voice communication capabilities, they lack accurate positioning and flexible command feedback mechanisms. To address these issues, this application provides an efficient, stable, and accurate solution through innovative system architecture and module integration.

[0037] The core components of the wireless broadcast walkie-talkie system in this embodiment include: a wireless broadcast transmitting unit 1, a two-way wireless communication module 2, a GPS receiving unit 3, a location data transmission module 4, a battery and power management unit 5, and a central control system 6. These modules are interconnected and work together through wireless communication and data transmission to achieve timely delivery of broadcast information, stable two-way voice communication, accurate real-time positioning, and high system efficiency.

[0038] like Figure 1 As shown, the wireless broadcasting unit 1 is responsible for broadcasting audio information to a designated area via radio waves, ensuring that the system's broadcasting function can cover every corner of the site. This unit includes an audio processing unit 11 and a modulation / demodulation unit 12. The main function of the audio processing unit 11 is to enhance, filter, and process the input audio signal to ensure clear and distortion-free sound quality. The modulation / demodulation unit 12 converts the audio signal into electromagnetic waves suitable for wireless propagation, modulates them, and transmits them through the antenna, ensuring that the broadcast signal covers and is transmitted clearly within a certain area.

[0039] This module enables two-way voice communication between various devices in the system. Each walkie-talkie includes a voice encoding / decoding unit 21, a wireless communication unit 22, and a microphone and speaker unit 23. The voice encoding / decoding unit 21 compresses the voice signal before transmission, improving communication efficiency while ensuring clear voice transmission. The wireless communication unit 22 uses frequency hopping technology to prevent signal interference, ensuring stable communication even in complex environments. The microphone and speaker unit 23 is responsible for voice acquisition and output, ensuring that users can clearly hear instructions or engage in real-time communication.

[0040] like Figure 1As shown, each device is equipped with a high-sensitivity GPS receiver 31, which can receive signals from satellites in real time and calculate the current latitude and longitude of the device. Through differential GPS (DGPS) technology, positioning accuracy can be improved in complex environments, reducing positioning errors caused by multipath propagation or signal interference. This receiving unit, through precise positioning technology, enables the command center to obtain the real-time location information of each device, thereby achieving accurate personnel positioning in emergency command or security management.

[0041] The location data transmission module 4 is responsible for transmitting the real-time location information collected by the GPS receiving unit 3 to the central control system 6 via the wireless communication unit 22. This module adopts low-power wireless transmission technology to ensure that the location information can be continuously and stably transmitted to the control center, while minimizing the power consumption of the system. By transmitting equipment location data in real time, command personnel can know the current location of each device at any time, facilitating the effective scheduling of personnel and resources.

[0042] like Figure 1 As shown, to ensure the continuous and stable operation of the system, the battery and power management unit 5 provides power support to all modules in the system. This unit includes a rechargeable battery 51 and a battery management module 53. The rechargeable battery 51 can be replaced or charged as needed to ensure that the device can work continuously for a long time.

When the charge is lower than a preset value, a warning signal will be issued to prompt the user to charge or replace the battery in time.

[0043] The central control system 6, as the core management unit of the system, is responsible for receiving location information and voice feedback from all devices, and sending broadcast information and instructions as needed. The central control system 6 includes an information management unit 61, a location data receiving unit 63, and a communication interface 62. The information management unit 61 processes voice information from various devices and transmits it to the target device or broadcast unit; the location data receiving unit 63 receives location information from all devices and displays the real-time location of the devices on the map; the communication interface 62 ensures smooth data transmission between modules through wireless communication technology. The central control system 6 can also adjust broadcast content, issue emergency instructions, and monitor the execution of instructions based on the real-time situation on site, ensuring the timeliness and accuracy of instruction delivery and response.

[0044] This system can be flexibly customized and expanded according to actual needs. For example, in some application scenarios, more communication frequency bands can be added to support the system, making it adaptable to different wireless communication environments; more management functions can also be added to the central control system 6, such as automatic broadcasting in emergencies or execution of scheduled tasks. This system is not limited to emergency command, but can also be applied to various occasions that require wireless broadcasting and instant communication, such as large-scale public events, security patrols, logistics management, and other fields.

[0045] The following is the system workflow.

[0046] The command center transmits broadcast information through the central control system 6. The broadcast information is modulated by the modulation and demodulation unit 12 of the wireless broadcasting unit 1 and transmitted to the designated area via radio waves to ensure that on-site personnel can receive the instruction information.

[0047] On-site personnel communicate in real-time via two-way wireless communication module 2. Each device can communicate bidirectionally with other devices through wireless communication unit 22, ensuring seamless voice communication between commanders and personnel. Voice encoding and decoding unit 21 ensures clear voice transmission.

[0048] Each device acquires its location in real time via GPS receiver 3 and transmits the location information to the central control system 6 through location data transmission module 4. The commander views the device's location and performs dispatching operations through the central control system 6. Simultaneously, the devices can provide voice feedback as needed, reporting mission progress in real time or requesting further instructions.

[0049] The device ensures stable operation over extended periods through the battery and power management unit 5. The battery power monitoring module 52 provides real-time power display and issues warnings when the power is low, ensuring that the system will not interrupt operation due to insufficient power at critical moments.
