[0026] In this embodiment, a first aspect, a VHF radio maintenance fixture includes a planar plug-in board 100 for mounting various PCB modules. The planar plug-in board 100 is equipped with a front panel module 10, a first connection detection module 20, a digital module 30, an RF module 40, a second connection detection module 50, an intermediate frequency module 60, a power control module 70, a power voltage detection and signal generator module 80, and a connector module 90. The front panel module 10 is connected to the first connection detection module 20 via a ribbon cable, the first connection detection module 20 is connected to the digital module 30 via a ribbon cable, the digital module 30 is connected to the RF module 40 via the connector module 90, the RF module 40 is connected to the second connection detection module 50 via a ribbon cable, the second connection detection module 50 is connected to the intermediate frequency module 60 via a ribbon cable, and the power control module 70 is connected to the RF module 40 and the power voltage detection and signal generator module 80 via ribbon cables. The fixture lays each PCB module flat on the planar plug-in board 100, with both sides of each module completely exposed. Maintenance personnel can directly measure the signal transmission and reception process, control signals, and power parameters of each board using instruments, eliminating the need to painstakingly search for test points among stacked circuit boards as in traditional methods, greatly facilitating visual testing. The modules are connected by ribbon cables and connector modules 90. Compared to traditional methods such as frequent plugging and unplugging of RF coaxial connectors, this reduces problems such as increased contact resistance and VSWR, improves the stability and reliability of signal transmission, and extends the service life of connecting components. Integrating multiple functional modules such as the front panel module 10, the first connection detection module 20, the digital module 30, and the RF module 40 onto a single planar plug-in board 100 enables centralized testing and maintenance of multiple modules of the VHF radio, avoiding the use of multiple dispersed testing devices, improving maintenance efficiency, and reducing the equipment footprint.

[0027] In practical applications, the front panel module 10 serves as the human-machine interface, transmitting user input signals to the first connection detection module 20. The first connection detection module 20 performs preliminary detection and processing on the signals before transmitting them to the digital module 30 via a ribbon cable. The digital module 30 performs digitization and computation on the signals, then transmits the processed digital signals to the radio frequency (RF) module 40 via the connector module 90. The RF module 40 converts the digital signals into RF signals and performs power amplification and other processing. The processed RF signals are then transmitted to the second connection detection module 50. The second connection detection module 50 detects the RF signals and then transmits them to the intermediate frequency (IF) module 60. The IF module 60 performs IF processing on the signals for subsequent demodulation and other operations.

[0028] The power control module 70 is responsible for managing and distributing the power supply to the entire maintenance fixture. It connects to the RF module 40 via a ribbon cable, providing a stable operating power supply to the RF module 40. It also connects to the power voltage detection and signal generator module 80. The power voltage detection and signal generator module 80 detects whether the voltage output by the power control module 70 is normal, and can also generate specific test signals as needed to test the functionality of other modules.

[0029] Because the connections between the modules are clear and connected via ribbon cables and connector modules 90, maintenance personnel can use instruments to detect the signal transmission at the connection points of each module, determine whether there are interruptions, attenuation, distortion, or other problems in the signal transmission process from the front panel module 10 to the intermediate frequency module 60, and thus locate the signal transmission fault point.

[0030] By detecting the control signals at the cable connection points between the first connection detection module 20 and the front panel module 10, the digital module 30, and other modules, maintenance personnel can determine whether the control signals are transmitted and interacted normally, determine whether each module can work according to the expected control logic, and troubleshoot control signal-related faults.

[0031] The power supply voltage detection and signal generator module 80 can measure whether the output voltages of each power supply channel of the power control module 70 are within the normal range and whether there are problems such as voltage fluctuations or excessive ripple. At the same time, it can also detect the current consumption of each module during operation to determine whether there are abnormalities such as short circuits or overloads, so as to determine whether the power system is working properly and whether any modules have failed due to power supply problems.

[0032] Using the test signal generated by the power supply voltage detection and signal generator module 80, the signal is input to different modules, and the output response of the subsequent modules is observed to check whether the signal processing, conversion and other functions of each module are normal. For example, a specific digital signal is input to the RF module 40, and its output RF signal is checked to see if it meets the standard, thereby determining whether the RF module 40 is functioning properly.

[0033] In one or more possible embodiments of this utility model, the planar plug-in plate 100 includes a substrate 110. The substrate 110 includes a first support opening 111, a second support opening 112, a third support opening 113, a fourth support opening 114, and a fifth support opening 115, which are respectively distributed along a first direction and extend along a second direction. At least one set of protruding openings are respectively provided on the inner walls of the first support opening 111, the second support opening 112, the third support opening 113, the fourth support opening 114, and the fifth support opening 115 for connecting with a PC. The mounting hole 116 of module B is used for installation. The length of the fifth support opening 115 is less than the length of the fourth support opening 114. One end of the fifth support opening 115 is flush with one end of the fourth support opening 114. The substrate 110 has an L-shaped opening 117 located at the other end of the fifth support opening 115 and the fourth support opening 114 and distributed along the first direction. The length of the L-shaped opening 117 is the maximum inner wall distance between the third support opening 113 and the fifth support opening 115. A power supply voltage detection and signal generator module 80 is installed on the L-shaped opening 117. The substrate 110 of the planar plug-in board 100 has multiple support openings, grooves and openings, and mounting holes 116 on the inner wall. Each PCB module can be fixed by screws. This design provides a stable installation position for each module, ensures the stability of the module in the tooling, and reduces detection errors caused by shaking or poor contact. The substrate 110 features a compact and rationally designed structure with supporting openings, grooves, and other openings, making full use of space. This ensures that each module can be installed reasonably while keeping the overall fixture structure simple and easy to operate and maintain. For example, the L-shaped opening design not only meets the installation requirements of the power supply voltage detection and signal generator module 80 but also takes into account the positional relationship and size matching with other supporting openings.

[0034] In one or more possible embodiments of this utility model, a first groove 118 is provided between the first storage opening 111 and the second storage opening 112, and a first opening 119 is provided on the first groove 118 for mounting a PCB module.

[0035] In one or more possible embodiments of this utility model, a second groove 120 is provided between the third support opening 113 and the fourth support opening 114 for mounting a PCB module.

[0036] In one or more possible embodiments of this utility model, the substrate 110 is further provided with a third opening 122 located between the second support opening 112 and the L-shaped opening 117, for mounting a PCB module.

[0037] The aforementioned first support opening 111, second support opening 112, third support opening 113, fourth support opening 114, fifth support opening 115, L-shaped opening 117, first groove 118, and second groove 120 are used to assemble various PCB modules. Referring to the attached drawings, various PCB modules such as the front panel module 10, first connection detection module 20, digital module 30, RF module 40, second connection detection module 50, intermediate frequency module 60, power control module 70, power voltage detection and signal generator module 80, and connector module 90 can be laid flat and fixed to the substrate 110 with screws, ensuring that the front and back sides of each PCB module are completely exposed, allowing maintenance personnel to measure the signal transmission and reception process, control signals, and power parameters of each board using instruments.

[0038] In specific applications, the substrate 110 is precision machined into an integrated form using CNC technology. It is mainly used to provide structural support for the five major modules of an ultra-shortwave radio, enabling the circuit boards stacked inside the radio cavity to be converted into a flat state, facilitating the visual inspection of the front and back of the circuit boards.

[0039] Specifically, for example, a multi-channel power detection module is set on the substrate 110. The multi-channel power detection module includes a voltage regulator unit, a power isolation unit, an energy metering unit, a data isolation unit, a display unit, a microcontroller unit, a keyboard unit, and a multiplexer unit. The output terminal of the voltage regulator unit is connected to the power isolation unit and the microcontroller unit respectively. The output terminal of the power isolation unit is connected to the energy metering unit. The energy metering unit is interconnected with the data isolation unit. The microcontroller unit is interconnected with the data isolation unit. The output terminal of the microcontroller unit is connected to the display unit. The output terminal of the keyboard unit is connected to the microcontroller unit. The output terminal of the multiplexer unit is connected to the energy metering unit. This is used to select the path to be tested and measure and display the power parameters.

[0040] In practical applications, the multi-channel power supply detection unit includes a power supply detection circuit. This unit sequentially measures the voltage of nine power supplies on the power board assembly, significantly improving the power board detection efficiency. The core component of the module is the IM1266 power metering module from Aireda Optoelectronics, with a voltage range of 1-380V AC / DC, far exceeding the voltage range of the radio module under test, thus meeting project requirements. Its communication protocol adopts the standard protocol of the power industry general standard DL / T 645-2007, facilitating software development. The IM1266 is a single-phase AC / DC adaptive power metering module, capable of accurately measuring AC or DC parameters in the circuit without requiring module replacement. Its accuracy surpasses the national Class 1 standard. It can be easily connected to other C51 and ARM microcontrollers through corresponding interfaces to achieve automated data acquisition and monitoring functions.

[0041] For example, the audio generator unit provides the radio with an audio signal source of 1mV-1V amplitude and 300-3400Hz sine wave, mainly used for testing and judging the faults of the radio's audio transmission and reception channels.

[0042] For example, in field power supply units, when there is no mains power supply in the field, the radio's own battery is used for power supply. A control module and a voltage and current display module are installed between the battery and the radio's power supply cable.

[0043] The various modules of the radio are connected by flexible circuit board wires. For example, the above modules are connected by 4 flexible ribbon cables, 1 connector plug, and 2 RF cables. Test points are reserved in the middle of each connector to facilitate signal testing by maintenance personnel. Flexible circuit board wires are used to connect the circuit boards of each module on the planar plug-in board 100 to achieve electrical connection and physical installation consistency.

[0044] By adopting a flat aluminum alloy substrate 110 and integrating it with each PCB module, the three-dimensional stacked radio circuit boards that could not be observed or measured are transformed into planar, visually inspectable boards that can be observed and tested from both sides. This transforms the stacked circuit boards inside the radio cavity into a flat state, facilitating visual inspection of both sides of the circuit boards.

[0045] Secondly, a VHF radio repair kit includes a housing 200, a handle 300 on the top of the housing 200, a display component 400 on the front side of the housing 200, multiple control buttons 500 located on one side of the display component 400 on the housing 200, a storage box 600 for placing items movably mounted on the right side of the housing 200, a storage box 700 for placing VHF radio repair tools inside the housing 200, a detachable panel 710 mounted on the rear of the housing 200, a detachable power supply component 800 movably mounted on the lower part of the housing 200, and a limiting component 900 for limiting the power supply component 800 on the outside of the housing 200. The top of the enclosure 200 features a handle 300 for easy transport of the repair kit by maintenance personnel. Whether indoors or on-site for VHF radio repair, it is easily portable, improving maintenance mobility. The front of the enclosure 200 has a display unit 400 and control buttons 500. The display unit 400 visually displays relevant information during the repair process, such as test data and equipment status, while the control buttons 500 facilitate various operations, such as starting tests and adjusting parameters. This ergonomic layout allows for convenient operation and monitoring. A movable storage box 600 on the right side of the enclosure 200 can be used to store repair tools, spare parts, and other items for easy access by maintenance personnel, improving repair efficiency. Efficiency; the detachable panel 710 facilitates inspection and maintenance of the interior of the enclosure 200, and also facilitates the installation, disassembly, or replacement of the VHF radio repair tools placed inside; the enclosure 200 has a storage box 700 for storing the VHF radio repair tools, which protects the tools from damage such as collisions and squeezing during transportation or storage, and also makes the tools more organized and easier to store and manage; the lower part has a detachable power supply component 800, which allows for easy replacement of power supply equipment with different power capacities or types to meet the power requirements of different maintenance scenarios; and even if the power supply component 800 fails, it can be quickly disassembled for repair or replacement without affecting the use of the entire repair kit.

[0046] In one or more possible embodiments of this utility model, the limiting component 900 includes a limiting seat 910 installed at the bottom of the housing 200. A limiting band 920 is engaged with the limiting seat 910. One end of the limiting band 920 passes through the handle of the power supply component 800 and cooperates with a limiting bracket 930. A locking screw 940 for locking the end of the limiting band 920 is threaded onto the limiting bracket 930. Through the cooperation of the limiting seat 910, the limiting band 920, and the limiting bracket 930, the limiting component 900 can firmly fix the power supply component 800 to the housing 200, preventing the power supply component 800 from shaking or falling off during transportation or use, ensuring the stability and safety of power supply, and improving the overall reliability of the maintenance kit.
