[0061] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0062] Embodiment 1: Figures 1 to 6 As shown, a circuit board card detection device for a rod control and rod position system includes a detection cabinet 1, a circuit substrate 2, a main control component 3, a detection signal input component, a feedback signal output component 8, a power supply component, a temperature and humidity sensor 9, a communication unit 10 and a display component 11.

[0063] The circuit substrate 2 is arranged inside the detection cabinet 1 , and specifically can be arranged at the inner bottom of the detection cabinet 1 , for realizing the integrated installation of the main control component 3 , the detection signal input component and the feedback signal output component 8 .

[0064] The main control component 3 is mounted on the circuit substrate 2 , and the main control component 3 may be a main control chip of model STM32F407.

[0065] The detection signal input component is used to generate a detection signal for the board to be detected, and the output end of the detection signal input component is electrically connected to the board to be detected. Specifically, the detection signal input component includes a first detection signal input component 6 and a second detection signal input component 7.

[0066] The first detection signal input component 6 is embedded in the detection cabinet 1, and is used to generate a 0-30V AC voltage signal for the board to be detected. The input end of the first detection signal input component 6 is electrically connected to the power supply socket 4-1 set on the detection cabinet 1, and the first detection signal input component 6 can be connected to the 220V mains power through the power supply socket 4-1. The first detection signal input component 6 can be an adjustable AC output power supply, which is used to convert the 220V AC voltage into a 0-30V AC voltage signal, which is used to simulate the AC voltage signal required in the board operation environment. The first detection signal input component 6 is provided with a voltage adjustment knob, a voltage display screen and a power switch. The staff can directly use the voltage adjustment knob to make the first detection signal input component 6 output the AC voltage signal of the required value.

[0067] The second detection signal input component 7 is installed on the circuit substrate 2, and is used to generate 21 digital signals for the board to be detected. The input end of the second detection signal input component 7 is electrically connected to the main control component 3. The second detection signal input component 7 can be an A / D converter (including three 8-channel analog-to-digital (A / D) conversion chips), which is used to convert the analog voltage signal into the digital signal required in the board operation environment. The digital signal output by any channel of the second detection signal input component 7 is a% of the input voltage signal, where a% is a random value in the range of -60% to +110%. For example, the input voltage of the second detection signal input component 7 is 24V, where a% of the first channel is 20% (randomly generated by the main control component 3), then the digital signal output by the first channel is 4.8V; a% of the second channel is -30% (randomly generated by the main control component 3), then the digital signal output by the second channel is -7.2V; ...; a% of the 21st channel is 100% (randomly generated by the main control component 3), then the digital signal output by the 21st channel is 24V. In addition, the main control component 3 can control the opening of the corresponding channel according to the functional type of the board to be detected.

[0068] Assuming that the circuit board of the rod control position system has four functional types, the input signal of each functional type of circuit board is different during actual operation. Therefore, different detection signals need to be input according to the circuit board of different functional types. There are mainly two types of detection signals. The first type is a 0-30V AC voltage signal. The staff can directly determine whether to use this detection signal according to the type of circuit board. If this detection signal needs to be used, the input detection signal can be manually adjusted through the first detection signal input component 6 during the specific detection process.

[0069] The second type is digital signals. Each type of circuit board card needs to input digital signals for different channels (for example, type one board card needs to input digital signals for the 1st channel, the 2nd channel, the 6th channel, the 9th channel, the 19th channel, and the 20th channel; type two board card needs to input digital signals for the 3rd channel, the 4th channel, the 5th channel, the 6th channel, the 10th channel, the 14th channel, the 15th channel, and the 21st channel; type three board card needs to input digital signals for the 1st channel, the 7th channel, the 8th channel, the 9th channel, the 11th channel, the 12th channel, the 15th channel, and the 16th channel; type four board card needs to input digital signals for the 10th channel, the 11th channel, the 13th channel, the 14th channel, the 17th channel, the 18th channel, the 19th channel, and the 20th channel). Therefore, each functional type of circuit board corresponds to a detection mode. During specific detection, the staff needs to first determine the functional type of the board to be detected, and then select the detection mode for the main control component 3 through the control end according to the functional type of the board to be detected. The main control component 3 controls the second detection signal input component 7 to generate a corresponding detection signal according to the selected detection mode.

[0070] The feedback signal output component 8 is installed on the circuit substrate 2, and is used to collect the feedback signal generated by the board to be detected in response to the detection signal. The input end of the feedback signal output component 8 is electrically connected to the board to be detected, and the output end is electrically connected to the main control component 3. After the board to be detected inputs a 0-30V AC voltage signal and / or a digital quantity signal, it will output a corresponding digital quantity signal (i.e., the feedback signal of the present application). The feedback signal output component 8 can be a D / A converter (including eight 8-channel digital-to-analog (D / A) conversion chips), which is used to convert the output digital quantity signal (i.e., the feedback signal) into an analog quantity signal (i.e., the detection result data of the present application), and transmit the detection result data to the main control component 3.

[0071] Finally, the main control component 3 transmits the test result data to the display component 11 for display, and the staff can manually determine whether the tested board is normal based on the test result data. For example, the board to be tested has a 5-fold amplification function, and the test input signal is 2V voltage, then the feedback output signal should be 10V. If the final value deviates greatly from 10V, it means that the board is abnormal, otherwise, the board is normal.

[0072] Furthermore, the power supply component includes a first power supply component 4 and a second power supply component 5. The first power supply component 4 is arranged inside the detection cabinet 1, and is used to convert the 220V AC voltage into a 24V DC voltage. The input end of the first power supply component 4 is electrically connected to the power supply socket 4-1 arranged on the detection cabinet 1, and the output end is electrically connected to the main control component 3. The power supply socket 4-1 is used to connect to the 220V mains. The first power supply component 4 can be a 220V to 24V power supply module, and the 24V DC voltage generated by the first power supply component 4 is used as the working voltage of the circuit board card detection device of the entire rod control rod position system. The second power supply component 5 is installed on the circuit substrate 2, and is used to convert the 24V DC voltage into a positive and negative 15V DC voltage. The input end of the second power supply component 5 is electrically connected to the main control component 3, and the output end is electrically connected to the board to be detected. The second power supply component 5 can be a 24V to positive and negative 15V power supply module, and the second power supply component 5 is used to provide a stable DC power supply (i.e., a DC voltage signal) to the board to be detected.

[0073] The temperature and humidity sensor 9 is arranged inside the detection cabinet 1, and is used to obtain the temperature data and humidity data in the environment, and is connected to the main control component 3. The temperature and humidity sensor 9 can transmit the real-time temperature data and humidity data to the main control component 3, and the main control component 3 can display the temperature and humidity values ​​inside the detection cabinet 1 through the display component 11 to assist the staff to determine whether the circuit board card is normal, thereby improving the detection accuracy of the circuit board card detection device of the rod control rod position system of the present application.

[0074] The communication unit 10 is mounted on the circuit substrate 2 and is used to connect the main control component 3 with the control end. The communication unit 10 can be Ethernet, which can connect the main control component 3 with the control end, making it convenient for the staff to perform relevant operations on the main control component 3 (for example, selecting the detection mode).

[0075] The display component 11 is connected to the main control component 3, and the display component 11 may include a display screen for displaying the test result data of the board to be tested and the temperature and humidity data inside the test cabinet 1. The staff can view the test results of the tested board more intuitively through the display screen, and can more conveniently find the abnormal point of the board when the board is abnormal.

[0076] Further, such as Figure 1 , Figure 2 As shown, the circuit board card detection device of the rod control rod position system of the present application also includes a board card installation component arranged on the top surface of the detection cabinet 1. The board card installation component includes a gold finger socket 12-1, a board card support frame 12-3, a detection probe 12-2 and a movable probe support frame 12-4.

[0077] A row of gold fingers (gold fingers refer to a row of golden plug pins on the board) are provided on both opposite sides of the board to be tested. The gold finger socket 12-1 is used to connect with the first row of gold fingers of the board to be tested, and the detection probe 12-2 is used to connect with the second row of gold fingers of the board to be tested. When the two rows of gold fingers are connected, the board can be electrically connected with the circuit board card detection device of the rod control rod position system of the present application. The board support frame 12-3 is used to support the board to be tested to prevent the board from tipping over during the detection process. The movable probe support frame 12-4 is used to install the detection probe 12-2, and to move the detection probe 12-2 to connect with the second row of gold fingers of the board to be tested or to move the detection probe 12-2 to separate from the second row of gold fingers of the board to be tested.

[0078] The installation process of the board to be tested is as follows: first, insert the first row of gold fingers of the board to be tested into the gold finger socket 12-1, and make the board body of the board to be tested lean against the board support frame 12-3, and then move the detection probe 12-2 to the second row of gold fingers of the board to be tested through the movable probe support frame 12-4. The disassembly process is reversed.

[0079] Specifically, Figure 7 As shown, the movable probe support frame 12-4 includes a probe mounting plate 12-4a, a guide rod 12-4b, a guide rod support frame 12-4c, a support rod 12-4d, a first connecting rod 12-4e, a second connecting rod 12-4f, a movable handle 12-4g, a third connecting rod 12-4h and a third connecting rod support frame 12-4j. The probe mounting plate 12-4a is provided with a movable guide hole, and the movable guide hole is equipped with a guide support sleeve. The guide rod 12-4b is connected to the guide support sleeve, and the guide rod support frame 12-4c is used to install the guide rod 12-4b. The support rod 12-4d is connected to the probe mounting plate 12-4a, the axial first end of the first connecting rod 12-4e is connected to the support rod 12-4d, the axial first end of the second connecting rod 12-4f is hinged to the axial second end of the first connecting rod 12-4e, the movable handle 12-4g is connected to the axial second end of the second connecting rod 12-4f, the axial first end of the third connecting rod 12-4h is hinged to the axial second end of the second connecting rod 12-4f, the third connecting rod support frame 12-4j is hinged to the axial second end of the third connecting rod 12-4h, and the third connecting rod support frame 12-4j is used to install and support the third connecting rod 12-4h.

[0080] When it is necessary to move the detection probe 12-2 to the second row of gold fingers of the board to be detected through the movable probe support frame 12-4, it is only necessary to push the movable handle 12-4g downward, and the first connecting rod 12-4e, the second connecting rod 12-4f, and the third connecting rod 12-4h will pull the support rod 12-4d backward, thereby driving the probe mounting plate 12-4a to move backward (the probe mounting plate 12-4a will be guided by the guide rod 12-4b during the backward movement), so as to separate the detection probe 12-2 from the second row of gold fingers of the board to be detected. When it is necessary to move the detection probe 12-2 to the second row of gold fingers of the board to be detected through the movable probe support frame 12-4, it is only necessary to pull the movable handle 12-4g upward.

[0081] The board installation assembly of the present application can realize the installation and removal of the board to be tested and the detection device of the present application very conveniently and quickly.

[0082] Further, such as Figure 1 and Figure 2 As shown, the detection cabinet 1 is provided with a heat dissipation hole 1-1, and a fan is provided inside the detection cabinet 1. The main control component 3, the detection signal input component, the feedback signal output component 8, etc. generate heat when working. The long-term accumulation of heat will cause the temperature inside the detection cabinet 1 to rise. When the temperature inside the detection cabinet 1 is high, it will affect the working performance of each component of the detection device. The present application can effectively dissipate the heat of the detection device through the heat dissipation hole 1-1 and the fan, so that the detection device maintains good working performance.

[0083] The device of the present application can input a detection signal of the board to be detected that simulates the input signal during actual operation, can collect the feedback signal of the board to be detected to the detection signal, and can also convert the feedback signal into detection result data and display it through a display component, so that the staff can determine whether the board is normal or abnormal by analyzing the detection result data, thereby realizing comprehensive and efficient detection of the circuit board.

[0084] Embodiment 2: Figure 6 As shown, a method for detecting a circuit board card of a rod control rod position system comprises the following steps:

[0085] L1 installs the board to be detected through the board installation assembly so that the board to be detected is electrically connected to the main control component 3. Specifically, L1 specifically includes the following steps: L11 inserts the first row of gold fingers of the board to be detected into the gold finger socket 12-1, and makes the board body of the board to be detected lean against the board support frame 12-3.

The installation process of the board to be tested is as follows: first, insert the first row of gold fingers of the board to be tested into the gold finger socket 12-1, and make the board body of the board to be tested lean against the board support frame 12-3, and then move the detection probe 12-2 to the second row of gold fingers of the board to be tested through the movable probe support frame 12-4.

[0092] The second detection signal input component 7 is installed on the circuit substrate 2, and is used to generate 21 digital signals for the board to be detected. The input end of the second detection signal input component 7 is electrically connected to the main control component 3. The second detection signal input component 7 can be an A / D converter (including three 8-channel analog-to-digital (A / D) conversion chips), which is used to convert the analog voltage signal into the digital signal required in the board operation environment. The digital signal output by any channel of the second detection signal input component 7 is a% of the input voltage signal, where a% is a random value in the range of -60% to +110%. For example, the input voltage of the second detection signal input component 7 is 24V, where a% of the first channel is 20% (randomly generated by the main control component 3), then the digital signal output by the first channel is 4.8V; a% of the second channel is -30% (randomly generated by the main control component 3), then the digital signal output by the second channel is -7.2V; ...; a% of the 21st channel is 100% (randomly generated by the main control component 3), then the digital signal output by the 21st channel is 24V. In addition, the main control component 3 can control the opening of the corresponding channel according to the functional type of the board to be detected.

[0093] Assuming that the circuit board of the rod control position system has four functional types, the input signal of each functional type of circuit board is different during actual operation. Therefore, different detection signals need to be input according to the circuit board of different functional types. There are mainly two types of detection signals. The first type is a 0-30V AC voltage signal. The staff can directly determine whether to use this detection signal according to the type of circuit board. If this detection signal needs to be used, the input detection signal can be manually adjusted through the first detection signal input component 6 during the specific detection process.

[0094] The second type is digital signals. Each type of circuit board card needs to input digital signals for different channels (for example, type one board card needs to input digital signals for the 1st channel, the 2nd channel, the 6th channel, the 9th channel, the 19th channel, and the 20th channel; type two board card needs to input digital signals for the 3rd channel, the 4th channel, the 5th channel, the 6th channel, the 10th channel, the 14th channel, the 15th channel, and the 21st channel; type three board card needs to input digital signals for the 1st channel, the 7th channel, the 8th channel, the 9th channel, the 11th channel, the 12th channel, the 15th channel, and the 16th channel; type four board card needs to input digital signals for the 10th channel, the 11th channel, the 13th channel, the 14th channel, the 17th channel, the 18th channel, the 19th channel, and the 20th channel). Therefore, each functional type of circuit board corresponds to a detection mode. During specific detection, the staff needs to first determine the functional type of the board to be detected, and then select the detection mode of the main control component 3 through the control end according to the functional type of the board to be detected. The main control component 3 controls the second detection signal input component 7 to generate a corresponding detection signal according to the selected detection mode. The present application can select the mode of the main control component 3 through the control end and the communication unit 10.

[0095] The feedback signal output component 8 is installed on the circuit substrate 2, and is used to collect the feedback signal generated by the board to be detected in response to the detection signal. The input end of the feedback signal output component 8 is electrically connected to the board to be detected, and the output end is electrically connected to the main control component 3. After the board to be detected inputs a 0-30V AC voltage signal and / or a digital quantity signal, it will output a corresponding digital quantity signal (i.e., the feedback signal of the present application). The feedback signal output component 8 can be a D / A converter (including eight 8-channel digital-to-analog (D / A) conversion chips), which is used to convert the output digital quantity signal (i.e., the feedback signal) into an analog quantity signal (i.e., the detection result data of the present application), and transmit the detection result data to the main control component 3.

[0096] The display component 11 is connected to the main control component 3, and the display component 11 may include a display screen for displaying the test result data of the board to be tested and the temperature and humidity data inside the test cabinet 1. The staff can view the test results of the tested board more intuitively through the display screen, and can more conveniently find the abnormal point of the board when the board is abnormal. The temperature and humidity data inside the test cabinet 1 are detected by the temperature and humidity sensor 9. The temperature and humidity sensor 9 can transmit real-time temperature data and humidity data to the main control component 3, and the main control component 3 can display the temperature and humidity values ​​inside the test cabinet 1 through the display component 11 to assist the staff to determine whether the circuit board is normal, thereby improving the detection accuracy of the circuit board detection device of the rod control rod position system of the present application.

[0097] The method of the present application can input a detection signal of the board to be detected that simulates the input signal during actual operation, can collect the feedback signal of the board to be detected to the detection signal, and can also convert the feedback signal into detection result data and display it through a display component, so that the staff can determine whether the board is normal or abnormal by analyzing the detection result data, thereby realizing comprehensive and efficient detection of the circuit board.

[0098] The above-described embodiments are only descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solution of the present invention should fall within the protection scope of the present invention, and the technical contents for which protection is sought in the present invention have been fully recorded in the claims.
