[0002] With the development of science and technology, in order to better control the operation of various scientific and technological products, various switching devices are often used in scientific and technological products to achieve switching between working state or suspended working state between various products or products that cooperate with each other.

[0003] However, switches used to switch between active and suspended states for various products or cooperating products typically only have one control signal line energized at a time. This means that energizing multiple signal lines simultaneously can damage the switch. Furthermore, when there are a large number of mechanical switches, the current power states of each switch's channel signal lines must be managed in a greater number of states, significantly increasing control complexity.

[0047] In order to illustrate the technical solution described in this application, specific embodiments are provided below.

[0048] The present application provides a switch channel switching method, which can reduce the control difficulty and debugging difficulty of the overall equipment and improve the stability of the system.

[0049] See also Figure 1 , Figure 1 This is a flow chart of an implementation method of a switch channel switching method provided in an embodiment of the present application, comprising the following steps:

[0050] The present application provides a switch channel switching method, wherein a control output port of a control board is connected to a control input port of a function board, and an output interface of the function board is connected to a control pin of a radio frequency switch group, including:

[0051] S11: Receive channel switching control information through the control board.

[0052] S12: Processing the channel switching control information through the control board to obtain a control signal, and transmitting the control signal to the radio frequency switch group after pre-processing by the function board.

[0053] S13: The RF switch group completes the switching of the switch channel according to the control signal after the preset processing by the function board.

[0054] In this embodiment, the hardware used is modularized to avoid system coupling, and the hardware connections of various parts of the switch matrix system are cleverly performed. Through the corresponding software control method, the control of the multi-input and output non-full-switching non-holding type RF switch matrix is realized.

[0055] The control board is used to receive and process specific RF channel switching instructions and generate serial control signals for the serial-to-parallel function board.

[0056] The function board receives the serial control signal from the control board and converts it into a parallel control signal for the RF switch. The converted parallel control signal will also undergo voltage step-up conversion, such as converting the voltage from 1V to 12V, for input to the final RF switch.

[0057] The RF switch group is a combination of mechanical non-retentive RF switches used in this switch matrix, which is used to receive the control signal after the function board is converted and execute the switching of specific RF switches.

[0058] In an embodiment, in order to manage the operating status of multiple switches, control more accurately, reduce product design and development costs, reduce the control difficulty and debugging difficulty of the overall equipment, improve system stability, and better adapt to switch expansion needs, the control output port of the control board is first connected to the control input port of the function board, and the output interface of the function board is connected to the control pin of the RF switch group. After the control board receives the channel switching control information sent by the upper computer, the control board processes the channel switching control information to obtain a control signal, and the control signal is preset by the function board so that the control signal can be divided into multiple and transmitted to the RF switch group. Then, after the RF switch group recognizes the control signal, it performs control operations on the multiple switches included in the RF switch group to complete the switching of the switch channels, effectively reducing the difficulty of device control and improving the stability of control.

[0059] The scenarios for receiving channel switching control information through the control board include but are not limited to the following:

[0060] Scenario 1: When the host computer is turned on and the startup fluctuation voltage signal of the host computer is detected, the control board receives the channel switching control information.

[0061] Scenario 2: When the control board is started and in operation, it receives channel switching control information.

[0062] Scenario 3: When it is determined that the work task performed by the target device is completed, the user profile of the user operator of the target device is obtained. Based on the user profile, the host computer is instructed to generate channel switching control information and send the channel switching control information to the control board.

[0063] User profiles describe the user's habits in performing tasks on the target device and the timing of each task. Based on these habits and the timing of task execution, the timing of the next task can be determined.

[0064] Therefore, the host computer can be instructed to generate channel switching control information according to the user portrait, and the channel switching control information can be sent to the control board.

[0065] In one example, if Figure 7 The control board has x control output ports, such as IO1, IO2, IO3...IOx, etc. These control ports use the limited control pins of the control board (MCU) to expand as many serial control signal ports as possible. Each independent IOx can generate an independent serial control signal.

[0066] Now you can connect the IO1 of the control board to the control input interface of a function board. At this time, the serial signal output by the IO1 of the control board will pass through the function board to perform the serial-to-parallel operation of the control signal. In this way, the small number of pins of the IO1 interface realizes the control signal of 32 parallel RF switches.

[0067] These 32 effective RF switch control pins are distributed across the function board's SW1, SW2, and SW3 output interfaces. Each of these interfaces has 15 pins, for a total of 45 pins. Specifically, pins 1 through 11 of the SW1 interface, pins 1 through 11 of the SW2 interface, and pins 1 through 10 of the SW3 interface, for a total of 32 pins, serve as RF switch control pins. The remaining pins of SW1, SW2, and SW3—pins 12 through 15 of SW1, SW2, and SW3, and pins 11 through 15 of SW3—serve as the GNDs for the RF switch control lines.

[0068] For example, in a 3x12SF type switch matrix, a non-holding mechanical RF switch group can select three 1-to-4 switches SP4T to form Figure 7 The control port of the RF switch group needs to be connected to the 12 control signal lines led out from SW1, SW2, and SW3.

[0069] Among them, take 12 of the 32 effective RF switch control pins of the SW1, SW2, and SW3 interfaces in the function board as the control pins of this RF switch group, and connect the interface pins of the function board SW1, SW2, and SW3 to the corresponding control pins of the switch group. Figure 10 In the figure, you can see the specific wiring method:

[0070] SW1_1, SW1_2, SW1_3, and SW1_4 on the function board are connected to 1#1, 1#2, 1#3, and 1#4 of RF switch 1 in sequence (1#1, 1#2, 1#3, and 1#4 represent the control lines of channels 1, 2, 3, and 4 of RF switch 1, respectively).

[0071] SW2_1, SW2_2, SW2_3, and SW2_4 on the function board are connected to 2#1, 2#2, 2#3, and 2#4 of RF switch 2 in sequence (2#1, 2#2, 2#3, and 2#4 represent the control lines of channels 1, 2, 3, and 4 of RF switch 2, respectively).

[0072] SW3_1, SW3_2, SW3_3, and SW3_4 on the function board are connected to 3#1, 3#2, 3#3, and 3#4 of RF switch 3 in sequence (3#1, 3#2, 3#3, and 3#4 represent the control lines of channels 1, 2, 3, and 4 of RF switch 3, respectively).

[0073] Combine Figure 2 In some embodiments, the processing of the channel switching control information by the control board to obtain a control signal includes:

[0074] S21: parsing the channel switching control information through the control board to obtain status word parameters of the global switches of the switch matrix.

[0075] S22: Generate the control word parameter according to the status word parameter, and use the control word parameter as the control signal.

[0076] In this embodiment, in order to better and more accurately control the switch and thus control the control device, the channel switching control information is parsed and processed by the control board to obtain the status word parameters of the global switch of the switch matrix. The status of each switch in the switch matrix is recorded through the status word parameters of the global switch of the switch matrix. Then, the control word parameters are generated based on the status word parameters. The control word parameters serve as the control signal, so that the switch information that needs to be operated is recorded through the control word parameters, and finally the switching of the switch channel is completed.

[0077] In some embodiments, if the number of the RF switch groups is greater than or equal to 2, the control word parameters corresponding to each of the RF switch groups are different.

[0078] In this embodiment, in order to meet the control requirements of more switches and make the control more accurate and stable, if the number of the RF switch groups is greater than or equal to 2, the control word parameters corresponding to each RF switch group are different.

[0079] Combine Figure 3 In some embodiments, the parsing and processing of the channel switching control information by the control board to obtain the status word parameters of the global switches of the switch matrix includes:

[0080] S31: parsing the channel switching control information through the control board to obtain the switch number that the RF switch group needs to switch and the internal channel number corresponding to the switch number.

[0081] S32: If it is determined that the switch number and the internal channel number corresponding to the switch number are the target switch number and the target internal channel number, the historical status word parameters are updated according to the target switch number and the target internal channel number to obtain the status word parameters of the global switch of the switch matrix.

[0082] In this embodiment, in order to more accurately control the opening or closing of the switch, the channel switching control information is parsed and processed by the control board to obtain the switch number that needs to be switched by the RF switch group and the internal channel number corresponding to the switch number, so as to understand the switch number that needs to be controlled to switch and the internal channel number corresponding to the switch number. If it is determined that the switch number and the internal channel number corresponding to the switch number are the target switch number and the target internal channel number, the historical status word parameters are updated according to the target switch number and the target internal channel number to obtain the status word parameters of the global switch of the switch matrix.

[0083] Example, combined Figure 8 , the control board parses the channel switching instruction in the receive buffer and obtains the switch number Switch_Num that the RF switch matrix currently needs to switch and the channel number Switch_Port_Num inside the switch, such as Figure 7 The switches in RF switch group 1 of the RF switch matrix are numbered 1, 2, and 3, and the corresponding internal channel numbers within each switch are 1, 2, 3, and 4. To ensure the correct switch and channel numbers and prevent incorrect status words, it is necessary to verify the switch and channel numbers. In a 3x12SF switch matrix system, there are three 1-to-4 switches. The switch number, Switch_Num, can take values from 1 to 3. Since each switch has a 1-to-4 split, the internal channel number, Switch_Port_Num, can take values from 1 to 4.

[0084] If the switch number and channel number in the instruction are correct, the global array SW_STA is used to store the current state of the switch to be switched in the system, that is, SW_STA[Switch_Num] = Switch_Port_Num; for example, Switch_Num = 1, Switch_Port_Num = 4, then SW_STA[1] = 4, which means that the switch matrix will switch to channel 4 of switch No. 1.

[0085] In a 3x12SF switch matrix system, there are three 1-to-4 switches. The initial state of the switch status control word SW_STA is: SW_STA[1] = 0, SW_STA[2] = 0, SW_STA[3] = 0; this means that switches 1, 2, and 3 are all in the channel-off state. If the switch matrix is to switch to channel 4 of switch 1, the corresponding value of the global status control word SW_STA is: SW_STA[1] = 4, SW_STA[2] = 0, SW_STA[3] = 0.

[0086] During the process of generating the global switch status parameters for the switch matrix, the SW_STA array is used to store the current state of the switch to be switched. Each element of the SW_STA array independently stores the state of the corresponding switch. Changing the state of any one switch does not affect the states of other switches. Furthermore, the SW_STA array is a global variable and is not reset during the operation of the switch matrix, accurately recording the state of each switch.

[0087] It can be seen that the state management method for channel switching of the switch matrix proposed in this application is very stable and efficient. The state of each switch is stored independently. After each switch switching instruction is received, the corresponding element of the array SW_STA will be updated synchronously to store the state of the corresponding switch, while the states of other switches are still stored and will not be lost.

[0088] On the one hand, this ensures the storage of the status of non-retentive RF switches, and can store them independently even if the number of switches is large. On the other hand, there is no need to design separate and complex hardware devices to manage the channel status of these switches, reducing product R&D and production costs.

[0089] Combine Figure 4 In some embodiments, generating the control word parameter according to the status word parameter, wherein the control word parameter serves as the control signal, includes:

[0090] S41: Determine the starting position status information of the target switch to be switched in the RF switch group according to the status word parameter.

[0091] S42: Determine a target offset of the target switch to be switched in the RF switch group according to the switch number of the target switch to be switched in the RF switch group and preset control line offset information corresponding to the target switch to be switched.

[0092] S43: Determine the control word parameter according to the target offset and the initial position state information of the target switch to be switched in the RF switch group.

[0093] In this embodiment, in order to more accurately switch the switch channel, the starting position state information of the target switch to be switched in the RF switch group is first determined according to the state parameter, so as to determine the target offset of the target switch to be switched in the RF switch group according to the switch number of the target switch to be switched in the RF switch group and the preset control line offset information corresponding to the target switch to be switched, thereby determining the control word parameter according to the target offset and the starting position state information of the target switch to be switched in the RF switch group.

[0094] In one embodiment, combining Figure 9 To achieve this, we need to generate the 32-bit control word parameter LocalVal based on the status word parameter SW_STA[Switch_Num] of the switch matrix's global switches. First, we define the 32-bit control word parameter LocalVal variable. Each of the 32 bits of the localVal variable value corresponds to the 32-bit parallel control signal output by the function board. Each time the control word parameter generation process begins, each bit of localVal is initialized to 0, that is, localVal = 0x00000000. This initialization of the localVal variable ensures that it is automatically cleared before each loop entry, preventing localVal from generating incorrect status values.

[0095] Next, based on the switch matrix's global switch status word parameter SW_STA[Switch_Num], the starting position state Start_Index of each switch control line in the 32-bit control word LocalVal is calculated, thereby confirming the starting point of each switch. The starting position states of RF switches 1, 2, and 3 are all considered to be the values of bits 0, 1, 2, and 3 of the control word LocalVal.

[0096] The SET_PORT_VAL expression in SET_PORT_VAL(SW_STA[Switch_Num]) performs the following operation: shifting the value 0x00000001 left by the specified number of bits, which is obtained by subtracting 1 from the value of the parameter SW_STA[Switch_Num] within the parentheses. For SW_STA[Switch_Num], when the switch number Switch_Num = 1, that is, SW_STA[1] = 4. Therefore, the expression SET_PORT_VAL(SW_STA[Switch_Num]) simplifies to SET_PORT_VAL(4), which further indicates that 0x00000001 is shifted left by (4-1) bits, that is, 0x00000001<<3.

[0097] In short, the value of the expression SET_PORT_VAL(SW_STA[Switch_Num]) determines the starting position of the signal line of the switch with switch number Switch_Num at Start_Index in the 32-bit control word LocalVal. The switch offset is calculated as Offset = (Switch_Num - 1) * delta. Here, Offset represents the actual index difference between control line 1 of each switch and SW1_1 (bit 0).

[0098] The control signal line of each switch has an index difference relative to SW1_1 of the function board.

[0099] The offset of the control line of switch 1 is 0 because the control pin 1 of switch 1 is connected to SW1_1.

[0100] The offset of switch 2 is 11 because control pin 1 of switch 2 is connected to SW2_1, and the index difference is 11.

[0101] The offset of switch 3 is 22 because control pin 1 of switch 3 is connected to SW3_1, and the index difference is 22.

[0102] Note: In Offset = (Switch_Num - 1) * delta, Switch_Num is the switch number, and delta is the coefficient used in the corresponding calculation. For example, the coefficient used to calculate the offset of switch control line 1 is 0, the coefficient used to calculate the offset of switch control line 2 is 11, and the coefficient used to calculate the offset of switch control line 3 is 22.

[0103] According to the calculated starting position state Start_Index and the calculated offset Offset, a temporary value of the control word LocalVal specific to each switch is obtained, that is, Start_Index << Offset.

[0104] Next, the temporary control word of each switch is combined into the final control word LocalVal through the operation LocalVal |=, that is, LocalVal |= Start_Index << Offset.

[0105] The resulting 32-bit control word, LocalVal, corresponds to a switch control line where only one bit is 1 at any given moment, with the rest being 0. For example, on switch #1, bits 1#1, 1#2, 1#3, and 1#4 represent the control lines for channels 1, 2, 3, and 4 of RF switch #1, respectively, corresponding to bits 0, 1, 2, and 3 of the control word. At any given moment, only one bit of bits 0, 1, 2, and 3 is 1, with the rest being 0. This ensures that only one signal line of the switch is energized at any given moment, preventing the simultaneous energization of multiple signal lines from the same switch, potentially damaging the non-retentive RF switch.

[0106] In some embodiments, the control board has at least two control output ports, each of which is connected to a control input port of a function board, and the output interface of each function board is connected to a control pin of a radio frequency switch group.

[0107] In this embodiment, to better control the switches and reduce switch control costs, the control board has at least two control output ports, each of which is connected to a control input port on a function board. The output port of each function board is connected to a control pin on a RF switch group. The control board, combined with a corresponding number of function boards, can easily and conveniently expand a switch matrix with more RF inputs and outputs, significantly reducing the complexity of hardware connections and software control. The overall device structure is compact, and the corresponding switch matrix can significantly reduce hardware size. Furthermore, because each RF switch group corresponds to a unique 32-bit switch control word, LocalVal—for example, RF switch group 1 corresponds to LocalVal1, RF switch group 2 corresponds to LocalVal2, and RF switch group X corresponds to LocalValX—each switch group is independently controlled by its corresponding status word, LocalValX, preventing interference between the control signals of different switch groups.

[0108] For example, the IO1 interface of the control board is connected to function board 1, and function board 1 is connected to RF switch group 1, thus forming a 3x12SF switch matrix. If you need to expand to a 6x24SF switch matrix, you can use IO2 to connect to function board 2 based on the 3x12SF switch matrix formed by IO1, and function board 2 is then connected to RF switch group 2 to form a 6x24SF switch matrix. If 6x24SF still does not meet the needs, you can continue this expansion idea until the IOX of the control board is connected to function board X, and function board X is then connected to RF switch group X. It should be noted that the number of switches in the newly expanded switch group is not limited to 3 switches.

[0109] In some embodiments, the control signal is a serial signal.

[0110] The step of transmitting the control signal to the radio frequency switch group after the control signal is pre-processed by the function board includes:

[0111] The control signal is processed in parallel by the function board and then transmitted to the radio frequency switch group.

[0112] In this embodiment, in order to better control the RF switch group, and since the signal type of the control signal received by the control board is a serial signal, the control signal is processed in parallel by the function board, and the signal type of the control signal is converted into a parallel signal, and then transmitted to the RF switch group through each board respectively.

[0113] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
