[0046] The contents of this application will be further described in detail below with reference to the accompanying drawings.

[0047] like Figures 1 to 7 As shown, a walkie-talkie communication control device is used for walkie-talkie base stations or relay stations, including an RF module, a power supply module, a control module, and a chassis.

[0048] like Figures 4 to 7 As shown, the chassis is a rectangular shell, including a front panel and a rear panel.

[0049] like Figures 2 to 7 As shown, the control module includes a control motherboard, a control display board, and control signal lines. The control motherboard and the control display board are electrically connected via the control signal lines. The control display board is located in the front panel area.

[0050] like Figures 3 to 7 As shown, the RF module includes an RF power amplifier module, an RF receiver module, an excitation module, RF interface D1, RF interface D2, and a fan A1. The RF power amplifier module and the excitation module are connected by RF signals; the excitation module is connected by electrical signals to the control motherboard; the RF power amplifier module is connected by RF signals to RF interface D1; the RF receiver module is connected by RF signals to RF interface D2; RF interfaces D1 and D2 are located in the rear panel area; fan A1 is located in the front panel area; fan A1 is used for heat dissipation of the RF module.

[0051] like Figures 1 to 7 As shown, the radio frequency module includes a fan A2, which is located in the front panel area; the fan A2 is used for heat dissipation of the radio frequency module; the control module and the fan A1 are electrically connected; the control module and the fan A2 are electrically connected.

[0052] The control module monitors the equipment temperature and controls the on / off state and speed of fans A1 and A2 in segments based on the temperature to reduce noise and extend fan life. It avoids having only one fan running continuously, as prolonged operation of a single fan can lead to one fan working for significantly longer than the other, thus affecting its lifespan. The control module controls the two fans to alternate operation based on the number of startups, thereby balancing the working time of the two fans and improving their lifespan.

[0053] Specifically, when the temperature is below a set threshold, fans A1 and A2 may start alternately, with the fan speed selected based on the temperature. Alternatively, when the temperature is above the set threshold, fans A1 and A2 may start simultaneously. Furthermore, the speed of fans A1 and / or A2 can be controlled based on the temperature conditions.

[0054] like Figure 6 As shown, the front panel area includes air duct opening A1 and air duct opening A2; the airflow channels of air duct opening A1 and fan A1 are connected; the airflow channels of air duct opening A2 and fan A2 are connected.

[0055] like Figure 6 As shown, the front panel area also includes a control panel area for the human-computer interaction module. For example... Figure 6 and Figure 7 As shown, ears are also installed on the left and right sides of the front and rear panels. The mounting ears are used to house the walkie-talkie communication control unit as a standard component into a standard-sized chassis.

[0056] like Figures 1 to 7As shown, the power module is electrically connected to the RF module; the power module is also electrically connected to the control module; the power module includes fan B1, which is located in the rear panel area; fan B1 is used for heat dissipation of the power module. The front and rear panel arrangement of fans A1 and B1 reduces competition for airflow between the two heat dissipation channels, making it easier to form a rapid airflow for heat dissipation, and as a whole, the airflow circulation is smoother.

[0057] like Figures 3 to 5 As shown, the RF power amplifier module and the power supply module are located on the left and right sides of the control module; the RF receiver module and the excitation module are placed side by side below the control module.

[0058] like Figure 2 As shown, the control signal line is ribbon cable A; the human-machine interaction module includes a display control board; the main control board includes port A2; port A2 and the port on the display control board are electrically connected via ribbon cable A; the radio frequency power amplifier module includes port B1, and the main control board includes port B2; port B1 and port B2 are electrically connected via ribbon cable B. This facilitates the transmission of large amounts of signals.

[0059] like Figures 1 to 7 As shown, the control module includes a maintenance interface E, and the control motherboard is electrically connected to the maintenance interface E; the maintenance interface E is either a serial port or a parallel port, facilitating data transmission during maintenance.

[0060] like Figures 1 to 7 As shown, the control module includes a signal interface F, and the control motherboard is electrically connected to the signal interface F; the signal interface F is a network interface.

[0061] like Figures 1 to 7 As shown, the power module includes a power module and a power interface C1. The power interface C1 is used to connect to AC power and is electrically connected to the power module. The power interface C1 is located in the rear panel area.

[0062] like Figures 1 to 7 As shown, the power module includes a power module and a power interface C2. The power interface C2 is used to connect to DC power and is electrically connected to the power module. The power interface C2 is located in the rear panel area.

[0063] like Figures 1 to 7 As shown, the radio frequency module includes an air duct opening A3; the air duct opening A3 is used for the radio frequency module to allow heat dissipation air to enter or exit to the outside of the device, and the air duct opening A3 is located in the rear panel area.

[0064] like Figures 8 to 13As shown, the RF power amplifier module includes an upper shielding plate, an RF circuit board, and a lower shielding plate; the upper shielding plate covers the RF circuit board; the lower shielding plate covers the RF circuit board; the lower shielding plate covers heat dissipation fins, which are parallel to the airflow direction of fan A1; the upper shielding plate includes one or more receiving cavities for accommodating RF devices.

[0065] like Figure 10 One side of the upper shielding plate includes multiple areas for attaching to the device to be cooled. For example... Figure 12 On the other side of the upper shielding plate, multiple heat dissipation fins are arranged in parallel, and an airflow channel is formed between two heat dissipation fins; the direction of the airflow channel is parallel to the airflow direction of fan A1.

[0066] like Figure 11 The heat dissipation fins of the upper shielding plate include group A, group B, group C, and group D heat dissipation fins arranged sequentially from the edge to the center.

[0067] like Figure 11 Group A heat dissipation fins include symmetrically arranged heat dissipation fins A1 and A2; Group A heat dissipation fins surround Group B, Group C and Group D heat dissipation fins, constraining the overall direction of heat dissipation airflow.

[0068] like Figure 11 Group B heat dissipation fins include symmetrically arranged heat dissipation fins B1 and B2; Group C heat dissipation fins include symmetrically arranged heat dissipation fins C1 and C2; Group D heat dissipation fins include symmetrically arranged heat dissipation fins D1 and D2. In all three groups (B, C, and D), one end of the fin is lower than the other, and the height difference between the two ends decreases sequentially. This height difference extends along the fin body direction, with the closer to the center, the longer the height difference extends along the fin body direction. The length of the height difference extending along the fin body direction is less than half the length of the fin body. Lowering one end of the fin in the central area reduces wind resistance and facilitates airflow entry. The symmetrical distribution and extension of the height difference design allows for more efficient overall airflow and improves heat dissipation efficiency.

[0069] like Figure 12 and Figure 13 The upper shielding plate includes four cavities: cavity A, cavity B, cavity C, and cavity D, which are used to cover the corresponding shielding body.

[0070] like Figures 8 to 14 As shown, the control module includes at least one shielding cover, which covers a portion of the control motherboard. Figures 8 to 14As shown, the control module includes shielding cover K1 and shielding cover K2, which respectively cover a portion of the control motherboard.

[0071] In some embodiments, the chassis casing has a length of 403mm, a height of 45mm, and a width of 430mm. In some embodiments, any one of the 400MHz-470MHz, 450MHz-520MHz, and 350MHz-400MHz bands is used as the transmission frequency band.

[0072] The walkie-talkie communication control device of this application is used for walkie-talkie base stations or relay stations, and includes an RF module, a power supply module, a control module, and a chassis. The chassis is a rectangular shell, including a front panel and a rear panel. The control display board is located in the front panel area.
