Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments.

[0052] In order to solve the technical problem that the technical solutions of existing broadband and narrowband private network communication equipment in the prior art are relatively complex, the present application provides a broadband and narrowband private network communication equipment that can simplify the technical solutions of existing broadband and narrowband private network communication equipment.

[0053] Figure 1 This is one of the structural diagrams of a broadband and narrowband private network communication device provided in an embodiment of the present application. In one embodiment, it includes:

[0054] Broadband module, narrowband module, RF signal switching module, control module and antenna module;

[0055] The broadband module and the narrowband module are electrically connected to the two RF access ports of the RF signal switching module respectively; the control module is electrically connected to the control port of the RF signal switching module; the antenna module is electrically connected to the antenna access port of the RF signal switching module;

[0056] The control module is used to control the broadband module to be electrically connected to the antenna module, or to control the narrowband module to be electrically connected to the antenna module.

[0057] It should be noted that the broadband module is used to provide broadband transmission functions. For example, users can transmit image data or video data through the broadband module.

[0058] The narrowband module is used for narrowband transmission functions. For example, users can use the narrowband module to transmit voice or text data.

[0059] The control module achieves electrical communication between the broadband module and the antenna module, or between the narrowband module and the antenna module, by controlling the difference between the voltage value of the control port of the RF signal switching module and a preset voltage threshold. The preset voltage threshold can be determined based on the internal structure of the control RF signal switching module. This application does not impose any restrictions on this. For example, when the voltage of the control port of the RF signal switching module is greater than or equal to 3.3V, the broadband module and the antenna module are electrically connected. When the voltage of the control port of the RF signal switching module is less than 3.3V, the narrowband module and the antenna module are electrically connected.

[0060] When the broadband module is electrically connected to the antenna module, the antenna module can receive or transmit wireless signals with broadband frequencies. When the narrowband module is electrically connected to the antenna module, the antenna module can receive or transmit wireless signals with narrowband frequencies.

[0061] The embodiment of the present application provides a broadband and narrowband private network communication device. The broadband and narrowband private network communication device includes: a broadband module, a narrowband module, a radio frequency signal switching module, a control module and an antenna module; the broadband module and the narrowband module are electrically connected to the two radio frequency access ports of the radio frequency signal switching module respectively, the control module is electrically connected to the control port of the radio frequency signal switching module, and the antenna module is electrically connected to the antenna access port of the radio frequency signal switching module; the control module is used to control the broadband module to be electrically connected to the antenna module, or to control the narrowband module to be electrically connected to the antenna module. It can be seen that the control module of the technical solution of the present application is electrically connected to the control port of the radio frequency signal switching module, so that the broadband module can be electrically connected to the antenna module or the narrowband module can be electrically connected to the antenna module through the control module. It can be seen that the above technical solution realizes broadband communication and narrowband communication of the private network through the same antenna module, effectively reducing the complexity of the technical solution of the broadband and narrowband private network communication device, thereby reducing the cost of the broadband and narrowband private network communication device.

[0062] See also Figure 2 , Figure 2 This is a second structural diagram of a broadband and narrowband private network communication device provided in an embodiment of the present application. In one embodiment, the RF signal switching module includes a first single-pole double-throw antenna electronic switch chip, and the broadband module and the narrowband module are respectively electrically connected to two RF access ports of the first single-pole double-throw antenna electronic switch chip;

[0063] The control module is electrically connected to the control port of the first single-pole double-throw antenna electronic switch chip;

[0064] The antenna module is electrically connected to the antenna access port of the first single-pole double-throw antenna electronic switch chip.

[0065] It should be noted that this application uses a single-pole, double-throw (SPDT) antenna electronic switch chip to implement the RF signal switching module. The core function of the SPDT antenna electronic switch chip is to selectively connect a single RF input port to two output ports by switching the semiconductor device between on and off states. The RF input port is the antenna access port in this application, and the two output ports are the two RF access ports in this application.

[0066] See also Figure 3 , Figure 3Figure 3 is a schematic structural diagram of a wideband and narrowband private network communication device according to an embodiment of the present application. In an embodiment, the radio frequency signal switching module further comprises a second single-pole double-throw antenna electronic switch chip, and the first single-pole double-throw antenna electronic switch chip and the second single-pole double-throw antenna electronic switch chip are connected in series.

[0067] The wideband module is electrically connected to a radio frequency access port of the first single-pole double-throw antenna electronic switch chip.

[0068] The narrowband module is electrically connected to a radio frequency access port of the second single-pole double-throw antenna electronic switch chip.

[0069] The control module is electrically connected to a control port of the first single-pole double-throw antenna electronic switch chip and a control port of the second single-pole double-throw antenna electronic switch chip, respectively.

[0070] The antenna module is electrically connected to an antenna access port of the second single-pole double-throw antenna electronic switch chip.

[0071] It should be noted that the performance of single-pole double-throw antenna electronic switch chips produced by different manufacturers or manufacturing processes is different. The signal isolation degree between different ports of the single-pole double-throw antenna electronic switch chip is also different. When the isolation degree between the two radio frequency access ports of the single-pole double-throw antenna electronic switch chip is small, part of the power emitted by the narrowband module leaks to the radio frequency link of the wideband module, causing the devices of the radio frequency link of the wideband module to be damaged. For example, when the electromagnetic wave power emitted by the narrowband module is 37dBm, and the isolation degree between the two radio frequency access ports of the single-pole double-throw antenna electronic switch chip is 20dBm, part of the electromagnetic wave power emitted by the narrowband module leaks to the wideband module, thereby causing the devices of the radio frequency link of the wideband module to be damaged. In order to solve this problem, the technical solution of the present application is to connect the narrowband module and the wideband module to different single-pole double-throw antenna electronic switch chips respectively, so as to isolate the narrowband module and the wideband module. When the electromagnetic wave power emitted by the narrowband module is large, the signal power leaked by the narrowband module is introduced into the ground through the single-pole double-throw antenna electronic switch chip, thereby reducing the influence of the electromagnetic wave power emitted by the narrowband module on the wideband module, and effectively avoiding the damage of the devices of the radio frequency link on the wideband module. For example, please refer to Figure 3 , Figure 3 In the above example, LTE is the wideband module, DMR is the narrowband module, ANTENNA is the antenna module, CONTROL is the control module, and SPDT1 and SPDT2 are single-pole double-throw antenna electronic switch chips. Among them, the connection positions of the wideband module and the narrowband module can be interchanged. That is, the narrowband module is connected to SPDT2, and the wideband module is connected to SPDT1.

[0072] In an embodiment, the frequency of the wideband wireless signal received by the antenna module is 430-470 MHz.

[0073] Referring to Figure 4 , Figure 4 A flowchart of a communication method according to an embodiment of the present application is shown. In an embodiment, the method is applied to a wide / narrow band private network communication device, which comprises a wideband module, a narrowband module, a radio frequency signal switching module, a control module and an antenna module. The method comprises the following steps:

[0074] S401, receiving a communication mode instruction from a user.

[0075] The communication mode instruction is used to determine the communication mode of the wide / narrow band private network communication device. The communication mode includes a private network wideband communication mode and a private network narrowband communication mode.

[0076] Specifically, the wide / narrow band private network communication device provides a human-computer interaction window menu for the user to select. The user selects the corresponding option on the human-computer interaction window according to the current communication mode. Of course, the user can also input the current communication mode instruction to the wide / narrow band private network communication device through text input or voice input.

[0077] S402, the control module controls the radio frequency signal switching module to switch to the first communication mode according to the communication mode instruction.

[0078] Specifically, when the communication mode instruction indicates that the current communication mode of the wide / narrow band private network communication device is the private network wideband communication mode, the control module controls the radio frequency signal switching module to switch to the first communication mode according to the communication mode instruction, so that the wideband module is electrically connected to the antenna module. When the communication mode instruction indicates that the current communication mode of the wide / narrow band private network communication device is the private network narrowband communication mode, the control module controls the radio frequency signal switching module to switch to the first communication mode according to the communication mode instruction, so that the narrowband module is electrically connected to the antenna module.

[0079] S403, the antenna module transmits and receives wireless signals in the communication mode.

[0080] The antenna module receives wireless signals in the private network wideband communication mode and transmits the wireless signals to the wideband module. At the same time, the wideband module transmits wireless signals to the outside through the antenna module.

[0081] The antenna module receives wireless signals in the private network narrowband communication mode and transmits the wireless signals to the narrowband module. At the same time, the narrowband module transmits wireless signals to the outside through the antenna module.

[0082] Referring to Figure 5 , Figure 5This is one of the flow diagrams of a communication method provided in an embodiment of the present application. In one embodiment, the method further includes:

[0083] S501: The antenna module receives a target wireless signal.

[0084] The target wireless signal is a wireless signal in a private network broadband communication mode or a wireless signal in a private network narrowband communication mode.

[0085] S502: The control module controls the radio frequency signal switching module to switch to the second communication mode.

[0086] The second communication mode is a private network broadband communication mode or a private network narrowband communication mode. For example, when the second communication mode is a private network broadband communication mode, the control module controls the RF signal switching module to switch modes according to the first communication mode, so that the broadband module is electrically connected to the antenna module.

[0087] It should be noted that the first communication mode and the second communication mode may be the same or different. When the first communication mode and the second communication mode are the same, there is no need to execute S502.

[0088] S503: Determine whether the target wireless signal can be parsed; if so, execute S504; if not, execute S505.

[0089] For example, the broadband module receives the target wireless signal and parses the target wireless signal. If the target wireless signal can be successfully parsed, S504 is executed; otherwise, S505 is executed.

[0090] S504: Keep the broadband and narrowband private network communication equipment in the second communication mode.

[0091] When the broadband and narrowband private network communication equipment can normally analyze the target wireless signal, there is no need to control the radio frequency signal switching module to switch the communication mode.

[0092] S505: The control module controls the radio frequency signal switching module to switch to the third communication mode.

[0093] Among them, the third communication mode is a private network broadband communication mode or a private network narrowband communication mode, and the third communication mode is different from the second communication mode.

[0094] When the broadband and narrowband private network communication device cannot normally parse the target wireless signal in the second communication mode, the control module needs to control the radio frequency signal switching module to switch the communication mode so that the broadband and narrowband private network communication device can successfully parse the target wireless signal.

[0095] In an embodiment, when the communication mode is the private network broadband communication mode, the frequency of the wireless signal is 430MHz-470MHz.

[0096] Referring to Figure 6 , Figure 6 is a schematic block diagram of a communication device provided by an embodiment of the present application. Corresponding to the above communication method, the present application also provides a communication device. The communication device comprises units for performing the above communication method, and the communication device can be configured in a desktop computer, a tablet computer, a laptop computer, and the like terminal.

[0097] A first receiving unit 601 is configured to receive a communication mode instruction from a user;

[0098] A switching unit 602 is configured to control the radio frequency signal switching module to switch to a first communication mode according to the communication mode instruction of the user by the control module, so that the broadband module is in electrical communication with the antenna module or so that the narrow band module is in electrical communication with the antenna module, and the first communication mode comprises a private network broadband communication mode or a private network narrow band communication mode;

[0099] A second receiving unit 603 is configured to receive wireless signals by the antenna module in the first communication mode.

[0100] In an embodiment, the second receiving unit 603 is further configured to receive a target wireless signal by the antenna module, and the communication device further comprises:

[0101] A judging unit 604 is configured to judge whether the target wireless signal can be parsed;

[0102] In an embodiment, the switching unit 602 is further configured to control the radio frequency signal switching module to switch to a second communication mode by the control module, and the second communication mode is the private network broadband communication mode or the private network narrow band communication mode.

[0103] In an embodiment, if the target wireless signal cannot be parsed, the switching unit 602 is further configured to control the radio frequency signal switching module to switch to a third communication mode by the control module, and the third communication mode is different from the second communication mode.

[0104] In an embodiment, when the communication mode is the private network broadband communication mode, the frequency of the wireless signal is 430MHz-470MHz.
