Technical Field

[0001] The present application relates to the field of long-wave signaling technology, and in particular to a tuning system and a control method. Background Art

[0002] In high-power long-wave systems, adjustable inductance is often used to achieve tuning. The adjustable inductance is provided with a coaxial fixed frame and a movable frame, the movable frame can rotate around the axis, and the stator coil and the movable coil are wound on the fixed frame and the movable frame respectively. When the overlap between the stator coil and the movable coil changes, the inductance value connected to the tuning circuit also changes accordingly.

[0040] The present application is further described in detail below in conjunction with the accompanying drawings.

[0041] Embodiment 1

[0042] Reference Figures 1 to 3 This embodiment discloses a tuning system, including a control device 1, a first adjustable inductor 2, a second adjustable inductor 4, an adjustment switch 5, a first position detection component 3, a second position detection device 7 and a switch position detection component 6, wherein the control device 1 includes a control module 11 and an industrial data acquisition module 12. The control module 11 is specifically a PLC. The model of the industrial data acquisition module 12 is specifically 8DIDC24V / SRC. The control module 11 and the industrial data acquisition module 12 communicate with each other through a network. The use of network communication has a strong anti-interference ability in a strong magnetic environment, which is conducive to achieving real-time and accurate control in the tuning system.

[0043] Reference Figure 1, the first adjustable inductor 2 includes a first moving frame 21, a first driving member 22, a first fixed frame 23 sleeved on the outer periphery of the first moving frame 21, a first movable coil 24 arranged on the first moving frame 21, and a first stator coil 25 arranged on the first fixed frame 23. The first movable coil 24 is arranged on part of the first moving frame 21, while the first movable coil 24 is not arranged on another part of the first moving frame 21. The first stator coil 25 is arranged on part of the first fixed frame 23, while the second movable coil 44 is not arranged on another part of the first fixed frame 23. For example, the first movable coil 24 covers half of the area on the outer peripheral surface of the first moving frame 21, and the first movable coil 24 covers half of the area on the outer peripheral surface of the first fixed frame 23. In the initial state, the position of the first movable coil 24 corresponds to the position of the first fixed frame 23 where the first stator coil 25 is not arranged; the position of the first definition coil corresponds to the position of the first moving frame 21 where the first movable coil 24 is not arranged. As the first movable skeleton 21 rotates, the overlapping area of ​​the first movable coil 24 and the first stator coil 25 gradually increases. The transmission shaft of the first driving member 22 is connected to the axis of the first movable skeleton 21. When the transmission shaft rotates, the first movable skeleton 21 rotates relative to the first fixed skeleton 23. Since the first movable coil 24 is only provided at a part of the first movable skeleton 21, and the first stator coil 25 is also only provided at a part of the first fixed skeleton 23, during the rotation of the first movable skeleton 21, the overlapping area of ​​the first movable coil 24 and the first stator coil 25 will change, that is, the overlap degree of the first movable coil 24 and the first stator coil 25 changes, so that the inductance value of the first adjustable inductor 2 is variable. Specifically, the first stator coil 25 is connected to the tuning circuit of the tuning system.

[0044] There is a corresponding relationship between the position of the first movable skeleton 21 and the inductance value of the first adjustable inductor 2. Figure 1 In order to enable the control device 1 to adjust the inductance value of the first adjustable inductor 2 accordingly by adjusting the position of the first movable frame 21, the first position detection component 3 is used to detect the position of the first movable frame 21. Specifically, the output end of the first position detection component 3 is connected to the input end of the industrial data acquisition module 12, and the output end of the industrial data acquisition module 12 is connected to the control end of the first driving member 22.

[0045] Reference Figure 1The first position detection component 3 specifically realizes the position detection of the first movable skeleton 21 through the grating disk 31 and the photoelectric encoder 32 matched with the grating disk 31. Specifically, the axis of the grating disk 31 is connected to the axis of the first movable skeleton 21. The light emitting end of the photoelectric encoder 32 is located on one side of the grating disk 31, and the light receiving end of the photoelectric encoder 32 is located on the other side of the grating disk 31. The light emitted by the light emitting end of the photoelectric encoder 32 passes through the code channel on the grating disk 31 and is received by the light receiving end of the photoelectric encoder 32, and the photoelectric encoder 32 forms a code accordingly. The industrial data acquisition module 12 collects the code emitted by the photoelectric encoder 32 and sends it to the control module 11. The control module 11 parses the code to know the position of the grating disk 31 and the first movable skeleton 21.

[0046] Reference Figure 1 and Figure 3 , the second adjustable inductor 4 is connected in series with the first adjustable inductor 2, and the structure of the second adjustable inductor 4 is similar to that of the first adjustable inductor 2. The second adjustable inductor 4 includes a second movable skeleton 41, a second driving member 42, a second fixed skeleton 43 sleeved on the outer periphery of the second movable skeleton 41, a second movable coil 44 arranged on the second movable skeleton 41, and a second stator coil 45 arranged on the second fixed skeleton 43. The output shaft of the second driving member 42 is connected to the axis of the second movable skeleton 41 to drive the second movable skeleton 41 to rotate relative to the second fixed skeleton 43. When the second movable skeleton 41 rotates, the overlap between the second movable coil 44 and the second stator coil 45 changes. The matching relationship between the second position detection device 7 and the second movable skeleton 41 is similar to the matching relationship between the first position detection component 3 and the first movable skeleton 21, and will not be repeated here.

[0047] Reference Figure 2The regulating switch 5 includes a fixing frame 56 and a first conductive contact 51, a second conductive contact 52 and a third conductive contact 53 arranged on the fixing frame 56. The first conductive contact 51, the second conductive contact 52 and the third conductive contact 53 are arranged in sequence along a straight line, and the length of the conductive member 54 is greater than the travel from the first conductive contact 51 to the second conductive contact 52 and then to the third conductive contact 53, so that after the conductive member 54 moves to a certain position, it can be electrically connected to the first conductive contact 51, the second conductive contact 52 and the third conductive contact 53 at the same time. The end of the first adjustable inductor 2 away from the second adjustable inductor 4 is connected to the first conductive contact 51, the connection between the first adjustable inductor 2 and the second adjustable inductor 4 is connected to the second conductive contact 52, and the end of the second adjustable inductor 4 away from the first adjustable inductor 2 is connected to the third conductive contact 53. The regulating switch 5 also includes a third driving member 55 and a conductive member 54. The third driving member 55 is connected to the conductive member 54 through an insulated transmission shaft to drive the conductive member 54 to move back and forth along the arrangement direction of the first conductive contact 51, the second conductive contact 52 and the third conductive contact 53. During the movement, the conductive member 54 causes the adjustment switch 5 to enter the first connection state, the second connection state or the third connection state respectively. In the first connection state, the first conductive contact 51 is electrically connected to the conductive member 54. At this time, only the end of the first adjustable inductor 2 away from the second adjustable inductor 4 is connected to the conductive member 54, and the first adjustable inductor 2 and the second adjustable inductor 4 are not short-circuited, that is, the first adjustable inductor 2 and the second adjustable inductor 4 are both connected to the tuning circuit. In the second connection state, the first conductive contact 51 and the second conductive contact 52 are both electrically connected to the conductive member 54. At this time, both ends of the first adjustable inductor 2 are connected to the conductive member 54, the first adjustable inductor 2 is short-circuited, and the second adjustable inductor 4 is connected to the tuning circuit. In the third connection state, the first conductive contact 51, the second conductive contact 52 and the third conductive contact 53 are all electrically connected to the conductive member 54. At this time, both ends of the first adjustable inductor 2 and the second adjustable inductor 4 are connected to the conductive member 54, and the first adjustable inductor 2 and the second adjustable inductor 4 are both short-circuited. During the movement of the conductive member 54, the switch position detection component 6 detects the position of the conductive member 54 and sends a position signal of the conductive member 54 to the industrial data acquisition module 12 of the control device 1. The switch position detection component 6 specifically includes a first travel switch 61, a second travel switch 62, a third travel switch 63 and a pressing block 64. The pressing block 64 is arranged on the conductive member 54 or on the transmission shaft of the third driving member 55. When the conductive member 54 moves to the position connected to the first conductive contact 51, the pressing block 64 contacts the trigger end of the first travel switch 61 to make the first travel switch 61 turned on, and the industrial data acquisition module 12 receives the signal that the first travel switch 61 is turned on, and the control device 1 knows that the adjustment switch 5 is in the first connection state.When the conductive member 54 moves to a position connected with the second conductive contact 52, the pressing block 64 contacts the trigger end of the second travel switch 62, causing the second travel switch 62 to be turned on, and the industrial data acquisition module 12 receives a signal that the second travel switch 62 is turned on, and the control device 1 learns that the adjustment switch 5 is in the second connection state. When the conductive member 54 moves to a position connected with the third conductive contact 53, the pressing block 64 contacts the trigger end of the third travel switch 63, causing the third travel switch 63 to be turned on, and the industrial data acquisition module 12 receives a signal that the third travel switch 63 is turned on, and the control device 1 learns that the adjustment switch 5 is in the third connection state.

[0048] Embodiment 2

[0049] The present application discloses a control method corresponding to the tuning system described in Example 1. The control method is applied to the control device 1 described in Example 1. The control device 1 includes a control module 11 and an industrial data acquisition module 12. The control module 11 and the industrial data acquisition module 12 communicate with each other through a network. The control module 11 is specifically a PLC. Figures 4 to 8 , the control method comprises the following steps:

[0050] S01: Establish a switch two-dimensional array 8, in which the switch serial number is used as the switch two-dimensional array row identifier 81, the operating frequency is used as the switch two-dimensional array column identifier 82, and the switch position parameter is used as the switch two-dimensional array content 83.

[0051] A switch two-dimensional array 8 is established in the control module 11. The switch two-dimensional array 8 is specifically a DB data block in the PLC. Fig. 9 , a switch two-dimensional array content 83 in the switch two-dimensional array 8 corresponds to a switch two-dimensional array row identifier 81 and a switch two-dimensional array column identifier 82, that is, a switch position parameter corresponds to a switch serial number and an operating frequency. When the control module 11 calls the switch two-dimensional array 8, it can index the corresponding switch position parameter and switch serial number according to the operating frequency.

[0052] When establishing the switch two-dimensional array 8, the following steps are included:

[0053] S011: Obtaining a switch number, an operating frequency, and corresponding switch position parameters based on the user's operation.

[0054] S012 : If there is no value identical to the switch serial number in the switch two-dimensional array row identifier 81 of the switch two-dimensional array 8 , the switch serial number is stored as a new switch two-dimensional array row identifier 81 in the switch two-dimensional array 8 .

[0055] S013 : If there is no value identical to the operating frequency in the switch two-dimensional array column identifier 82 of the switch two-dimensional array 8 , the operating frequency is stored as a new switch two-dimensional array column identifier 82 in the switch two-dimensional array 8 .

[0056] S014: storing the switch position parameter in a data position where the switch two-dimensional array row identifier 81 is the switch serial number and the switch two-dimensional array column identifier 82 is the operating frequency.

[0057] When there are multiple adjustment switches 5 in the tuning circuit, the control module 11 uses the switch serial number to identify which adjustment switch 5 the data in the switch two-dimensional array 8 is applicable to. Specifically, different adjustment switches 5 are connected to different ports in the industrial data acquisition module 12, and there is a corresponding relationship between different ports and switch serial numbers. When the industrial data acquisition module 12 communicates with the adjustment switch 5 corresponding to a certain switch serial number, it actually communicates through the port corresponding to the switch serial number.

[0058] After the user manually inputs the switch number, operating frequency and corresponding switch position parameters to the control module 11, the control module 11 obtains the switch number, operating frequency and switch position parameters accordingly. The switch number, operating frequency and switch position parameters are all numerical values.

[0059] S02: establishing an inductor two-dimensional array 9, wherein the inductor serial number is used as an inductor two-dimensional array row identifier 91, the operating frequency is used as an inductor two-dimensional array column identifier 92, and the inductor position parameter is used as an inductor two-dimensional array content 93.

[0060] A two-dimensional inductance array 9 is established in the control module 11. The two-dimensional inductance array 9 is specifically a DB data block in the PLC. Fig.10 , an array content in the inductor two-dimensional array 9 corresponds to a row identifier and a column identifier, that is, an inductor position parameter corresponds to an inductor serial number and an operating frequency. When the control module 11 calls the inductor two-dimensional array 9, it can index the corresponding inductor serial number and operating frequency according to the operating frequency.

[0061] When establishing the two-dimensional inductor array 9, the following steps are included:

[0062] S021: Obtaining the inductor serial number, operating frequency, and corresponding inductor position parameters based on the user's operation.

[0063] S022 : if there is no value identical to the inductor serial number in the row identifier of the inductor two-dimensional array 9 , the inductor serial number is stored as a new inductor two-dimensional array row identifier 91 in the inductor two-dimensional array 9 .

[0064] S023 : If there is no value in the column identifier of the inductor two-dimensional array 9 that is the same as the operating frequency, the operating frequency is stored as a new inductor two-dimensional array column identifier 92 in the inductor two-dimensional array 9 .

[0065] S024: storing the inductance position parameter in a data position where the inductance two-dimensional array row identifier 91 is the inductance serial number and the inductance two-dimensional array column identifier 92 is the operating frequency.

[0066] When there are multiple adjustable inductors in the tuning circuit, the control module 11 uses the inductor serial number to identify which adjustable inductor the data in the two-dimensional inductor array 9 is suitable for. Specifically, different adjustable inductors are connected to different ports of the industrial data acquisition module 12, and there is a corresponding relationship between different ports and inductor serial numbers. When the industrial data acquisition module 12 communicates with the adjustable inductor corresponding to a certain inductor serial number, the signal is actually sent and received through the port corresponding to the inductor serial number.

[0067] After the user manually inputs the inductor serial number, operating frequency and corresponding inductor position parameters to the control module 11, the control module 11 correspondingly obtains the inductor serial number, operating frequency and inductor position parameters. The inductor serial number, operating frequency and inductor position parameters are all numerical values.

[0068] S03: Obtain the target operating frequency.

[0069] When the tuning circuit needs to operate at a certain operating frequency, the user inputs the target operating frequency to the control module 11 , and the control module 11 receives the target operating frequency.

[0070] S04: Based on the target operating frequency, searching the switch two-dimensional array 8 for a corresponding switch position parameter as a target switch position parameter, and searching the switch two-dimensional array 8 for a corresponding switch number as a target switch number.

[0071] The control module 11 calls the switch two-dimensional array 8 and searches the switch two-dimensional array 8 for corresponding switch position parameters and switch serial numbers according to the target operating frequency.

[0072] S05: Obtain the switch position of the regulating switch 5 corresponding to the target switch number to form a current switch position parameter.

[0073] The switch position is specifically the position where the conductive member 54 is located. After the industrial data acquisition module 12 receives the switch position sent by the switch position detection component 6, it sends the switch position to the control module 11, and the control module 11 converts it into the corresponding current switch position parameter according to the preset corresponding relationship. The switch position parameter is a plurality of values ​​of different sizes. Specifically, the switch position parameter corresponding to the first connection state, the switch position parameter corresponding to the second connection state, the switch position parameter corresponding to the third connection state, and the switch position parameter corresponding to the non-limiting state are values ​​arranged in sequence from small to large or in sequence from large to small. The non-limiting state refers to the state in which the conductive member 54 is located between two conductive contacts due to reasons such as sudden termination of the drive, that is, the state when the first travel switch 61, the second travel switch 62, and the third travel switch 63 are all not conducting. By introducing the non-limiting state, even if a special situation occurs that causes the adjustment switch 5 to be not in the normal state (the first connection state, the second connection state, and the third connection state), the control module 11 can also process it accordingly without getting a bug.

[0074] S06: Compare the target switch position parameters with the current switch position parameters to form a switch position comparison result.

[0075] The control module 11 compares the target switch position parameter with the actual switch position parameter to form a switch position comparison result.

[0076] S07: issuing a switch driving signal based on the switch position comparison result.

[0077] The control module 11 forms a switch drive instruction based on the switch position comparison result and sends the switch drive instruction to the industrial data acquisition module 12. After parsing the switch drive instruction, the industrial data acquisition module 12 sends a switch drive signal to the third drive member 55 of the adjustment switch 5. When the target switch position parameter is greater than the actual switch position parameter, the industrial data acquisition module 12 sends a drive signal to the third drive member 55 of the adjustment switch 5 to move in the first direction; when the target switch position parameter is less than the actual switch position parameter, the industrial data acquisition module 12 sends a drive signal to the third drive member 55 of the adjustment switch 5 to move in the second direction; when the target switch position parameter is equal to the actual switch position parameter, the industrial data acquisition module 12 does not send a drive signal to the third drive member 55 of the adjustment switch 5. The first direction and the second direction are opposite directions. For example, the first direction can be up and the second direction can be down; or the first direction can be left and the second direction can be right.

[0078] The switch position parameter corresponding to the first connection state, the switch position parameter corresponding to the second connection state, the switch position parameter corresponding to the third connection state, and the switch position parameter corresponding to the non-limiting state are taken as examples, which are numerical values ​​arranged in order from small to large, and the specific parameters and directions are defined as follows: the first direction is upward, and the second direction is downward; the conductive member 54 is connected to the first conductive contact 51, and the switch position detection component 6 detects that the first stroke switch 61 is turned on. The switch position parameter is "1" when the conductive member 54 is connected to the first conductive contact 51 and the second conductive contact 52, and the switch position detection component 6 detects that the second stroke switch 62 is turned on. The switch position parameter is "2" when the conductive member 54 is connected to the first conductive contact 51, the second conductive contact 52, and the third conductive contact 53, and the switch position detection component 6 detects that the third stroke switch 63 is turned on. The switch position parameter is "3" when the conductive member 54 is located between the two conductive contacts due to reasons such as sudden termination of driving, that is, the first stroke switch 61, the second stroke switch 62, and the third stroke switch 63 are not turned on. The switch position parameter is "4". The industrial data acquisition module 12 receives the switch position sent by the switch position detection component 6 and sends it to the control module 11. After the control module 11 converts and finds that the current switch position parameter is "2" and the target switch position parameter is "1", the control module 11 sends a switch drive instruction to the industrial data acquisition module 12. The industrial data acquisition module 12 correspondingly sends a downward moving drive signal to the third drive member 55 of the adjustment switch 5 so that the conductive member 54 of the adjustment switch 5 moves to the target position.

[0079] S08: Based on the target operating frequency, searching the inductor two-dimensional array 9 for a corresponding inductor position parameter as a target inductor position parameter, and searching the inductor two-dimensional array 9 for a corresponding inductor serial number as a target inductor serial number.

[0080] The control module 11 calls the inductor two-dimensional array 9 and searches for the corresponding inductor position parameters and inductor serial numbers in the inductor two-dimensional array 9 according to the target operating frequency. After searching, the control module 11 sends the found inductor position parameters and inductor serial numbers to the industrial data acquisition module 12.

[0081] S09: Acquire the inductance position of the adjustable inductor corresponding to the target inductance serial number to form a current inductance position parameter.

[0082] The inductance position is specifically the position of the first moving frame 21 / the second moving frame 41. The first position detection component 3 / the second position detection component 7 can directly encode according to the position of the first moving frame 21 / the second moving frame 41 and send it to the industrial data acquisition module 12, and the industrial data acquisition module 12 sends the received code to the control module 11.

[0083] S10: Compare the target inductor position parameter and the current inductor position parameter to form an inductor position comparison result.

[0084] The code is converted into a numerical value through binary conversion in the control module 11, and the control module 11 uses the converted numerical value as the current inductance position parameter. The control module 11 compares the target inductance position parameter with the current inductance position parameter to form an inductance position comparison result.

[0085] S11: issuing an inductor driving signal based on the inductor position comparison result.

[0086] The control module 11 sends an inductance driving instruction to the industrial data acquisition module 12 based on the inductance position comparison result, and the industrial data acquisition module 12 sends a driving signal to the first driving member 22 / second driving member 42 of the first adjustable inductor 2 / second adjustable inductor 4 accordingly. When the target inductance position parameter is greater than the actual inductance position parameter, the industrial data acquisition module 12 sends a driving signal to the first driving member 22 / second driving member 42 of the first adjustable inductor 2 / second adjustable inductor 4 to move in the third direction; when the target inductance position parameter is less than the actual inductance position parameter, the industrial data acquisition module 12 sends a driving signal to the first driving member 22 / second driving member 42 of the first adjustable inductor 2 / second adjustable inductor 4 to move in the fourth direction; when the target inductance position parameter is equal to the actual inductance position parameter, the industrial data acquisition module 12 does not send a driving signal to the first driving member 22 / second driving member 42 for adjusting the inductance 4 of the first adjustable inductor 2 / second adjustable inductor 4. The third direction and the fourth direction are opposite directions. For example, the third direction may be a clockwise rotation, and the fourth direction may be a counterclockwise rotation.

[0087] The driving mode and position detection mode of the first adjustable inductor 2 and the second adjustable inductor 4 are the same, so the first adjustable inductor 2 is taken as an example for explanation. The grating disk 31 used in the first position detection component 3 is an eight-bit grating disk 31, so the code output by the first position detection component 3 is 0 to 255 after binary conversion to a numerical value. Assume that the industrial data acquisition module 12 receives the code corresponding to the inductance position sent by the first position detection component 3 and sends it to the control module 11. After the control module 11 performs conversion, it is found that the current inductance position parameter is 196, and the target inductance switch position parameter is 1. Then, the control module 11 sends an inductance drive instruction to the industrial data acquisition module 12, and the industrial data acquisition module 12 sends an inductance drive signal to the first drive member 22 accordingly, so that the first drive member 22 rotates in the corresponding direction and rotates to the position where the inductance switch position parameter is 1.

[0088] S12: Generating another inductor driving signal based on the user's operation.

[0089] S13: issuing the other inductor driving signal.

[0090] When the tuning circuit is in use, the inductance value may need to be fine-tuned due to weather reasons. Therefore, after the industrial data acquisition module 12 sends a drive signal to the first drive member 22, the user can manually fine-tune it again. The user selects the adjustable inductor that needs to be controlled and performs a control operation through the panel connected to the control module 11. The control operation is specifically to control the adjustable inductor to rotate clockwise or counterclockwise. The control module 11 forms a corresponding control instruction based on the user's operation and sends it to the industrial data acquisition module 12. The industrial data acquisition module 12 correspondingly sends an inductance drive signal to the first drive member 22 / second drive member 42 of the first adjustable inductor 2 / second adjustable inductor 4 inductor 4, so that the first movable frame 21 / second movable frame 41 of the first adjustable inductor 2 / second adjustable inductor 4 inductor 4 rotates to the corresponding position.

[0091] S14: Obtaining the fine-tuning inductor position parameter after the adjustable inductor moves in response to the another inductor driving signal. S15: Replacing the target inductor position parameter in the inductor two-dimensional array 9 with the fine-tuning inductor position parameter.

[0092] After the first movable skeleton 21 / the second movable skeleton 41 completes the rotation, the industrial data acquisition module 12 receives the code corresponding to the inductance position sent by the first position detection component 3 / the second position detection component 7 and sends it to the control module 11. The control module 11 converts the code into a fine-tuning inductance position parameter, and replaces the inductance position parameter originally corresponding to the target operating frequency and the target inductance serial number in the inductance two-dimensional array 9 with the fine-tuning inductance position parameter.

[0093] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
