Description

Technical Field

[0001] The present invention relates to the field of optical instrument technology applications, and in particular to a CCD integrated acquisition board detection system and a detection method. Background Art

[0002] The fields of optical instrument manufacturing and automated detection and control are important components of modern science and technology. Full-spectrum spark direct reading spectrometer, one of the optical instruments, is widely used in the fields of metallurgical industry, engineering machinery and materials science. Full-spectrum spark direct reading spectrometer evaporates, atomizes and excites the analyte through spark discharge between electrodes, and emits a light signal containing characteristic spectral lines and light intensity information of different elements. The qualitative and quantitative analysis of the sample is achieved by processing the light signal. Full-spectrum direct reading spectrometer has unique advantages in directly analyzing solid samples, so there is still a great demand for it.

[0003] Problems with existing technologies: In practical applications, components of full-spectrum spark direct-reading spectrometers, such as CCD integrated acquisition boards, need to be tested to ensure production and sales quality and enhance user experience. The existing solution is to perform testing through on-machine operation, but this process is cumbersome, inconvenient, and a waste of manpower and material resources. In addition, existing detection methods cannot intuitively display signals, and cannot quickly and accurately determine whether the device can be used normally. These problems limit the widespread application and promotion of full-spectrum direct-reading spectrometers, and also affect user experience and use effects. Therefore, there is an urgent need for a new, more efficient, and more intuitive detection method to solve these problems. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a CCD integrated acquisition board detection system and detection method, which can display the signal intuitively for easy observation.

[0005] The technical solution of the present invention is: a CCD integrated acquisition board detection system, comprising a software module, a board under test, a power supply module, a signal display module and an acquisition module, wherein the power supply module is used to provide power to the board under test;

[0006] The software module is connected to the board under test through the TCP / IP protocol, and the board under test is respectively connected to the acquisition module and the signal display module, and the acquisition module caches the acquired data in the board under test through a coaxial cable, and transmits the data to the software module for processing;

[0007] The software module is provided with two groups and includes detection software 1 and detection software 2. The detection software 1 is connected to the acquisition module through the board under test, and the detection software 2 is connected to the signal display module through the board under test.

[0008] Furthermore, the board under test receives commands from the software module via FPGA.

[0009] Furthermore, the signal display module is provided with an LED indicator light, and the change of the path voltage is displayed by turning on or off the LED indicator light.

[0010] Furthermore, the acquisition module includes a charge coupler and a CCD conversion board. The charge coupler performs photoelectric conversion, and the obtained electrical signal is amplified by the CCD conversion board.

[0011] A CCD integrated acquisition board detection method comprises the following steps:

[0012] Step 1: Connect the acquisition module and the power supply module to the board under test respectively, ensure that the data connection and power supply are normal, and connect the board under test to the host computer software module;

[0013] Step 2: The software module is connected to the board under test through the network port;

[0014] Step 3, the software module includes detection software 1 and detection software 2, and the detection software 1 and the detection software 2 respectively control the program running in the FPGA on the board under test through transmission signals;

[0015] Step 4: The signal display module displays the signal through the LED indicator light; the acquisition module converts and amplifies the photoelectric signal and then transmits it back to the detection software 1.

[0016] Further, in step 1, the power supply module provides power supply that matches the working voltage to the board under test, and the power supply module includes a switching power supply. When the power indicator light of the switching power supply is normal, the power supply of the board under test is normal;

[0017] When the power indicator of the switching power supply flashes, the board under test is short-circuited and the voltage chip will quickly dissipate a lot of heat. The temperature measuring gun is used to accurately locate the heating part and determine whether the no-load output of the power chip is normal.

[0018] The no-load output of the power chip is abnormal, and the power chip should be replaced;

[0019] If the power chip outputs normally when not loaded, it is confirmed that the load part is short-circuited and the abnormal part should be replaced.

[0020] Furthermore, in step 2, the board under test is provided with 5 LED indicator lights, and the software module is connected to the network port of the board under test. When 2 LED indicator lights of the board under test are always on and 3 LED indicator lights flash alternately, it indicates that the program in the FPGA of the board under test is successfully burned. If only one LED indicator light flashes, it indicates that the program burning is abnormal.

[0021] Furthermore, in step 3, the detection software 1 is opened. If the network is displayed as normal, it indicates that the connection with the board under test has been successfully completed.

[0022] If the network is abnormal:

[0023] When the indicator light is normal, confirm whether the network address of the upper computer software module has been modified;

[0024] When the two constant-on indicators are off, check whether the network cable is properly plugged in;

[0025] When the two indicator lights are normally on, but cannot connect to the host computer software module, and the indicator lights do not flash, it indicates that the relevant resistance is abnormal.

[0026] Furthermore, in step 4, the acquisition module includes a charge coupler and a CCD conversion board. The detection software 1 controls the program running in the FPGA on the board under test by transmitting signals through the network port. The charge coupler performs photoelectric conversion and amplifies the converted electrical signal through the CCD conversion board. The amplified signal is transmitted to the board under test through a coaxial cable for data caching, and the data is transmitted back to the detection software 1 through the network port.

[0027] Further, in step 4, the signal display module includes an LED light board, and the detection software 2 controls the program running in the FPGA on the board under test by transmitting signals through the network port, and determines whether the board under test responds correctly to the software operation by turning on and off the LED light board;

[0028] When the level is high, the LED light board is on; when the level is low, the LED light board is off.

[0029] The beneficial technical effects of the present invention are:

[0030] 1. The present invention is controlled by a software module, and the data obtained by the acquisition module is transmitted to the software module for processing via the board under test. The characteristic that the first 15 pixels of the CCD are not sensitive to light is used to determine whether the board under test can normally transmit and process data and whether the external power supply and signal control are normal. This design can quickly and accurately determine whether the device can be used normally, thereby improving the accuracy of detection.

[0031] 2. Realize intuitive display of signals: The signal display module of the present invention adopts an LED light board, which can intuitively display the presence or absence of signals. This design makes the detection results clear at a glance, without the need for complex analysis and interpretation, greatly simplifies the operation process, and improves the user experience.

[0032] 3. Improved detection efficiency: The present invention controls the signal through the software module. When a certain signal is at a high level, the corresponding channel LED is lit, otherwise, it is extinguished. This can intuitively determine whether the software can correctly control the signal. This process has a high degree of automation and greatly improves the detection efficiency.

[0033] 4. Reduced waste of manpower and material resources: The design of the present invention makes the detection process simpler, reduces the tediousness and waste of manual operation, and also avoids errors and inaccuracies caused by manual operation errors.

[0034] 5. With the help of this system, the problematic parts can be directly identified during the detection process and repairs can be carried out.

[0035] The above description is only an overview of the technical solution of the present invention.

The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0040] like Figure 1 As shown, the present invention specifically relates to a CCD integrated acquisition board detection system, including a software module, a board under test, a power supply module, a signal display module and an acquisition module, wherein the power supply module is used to provide power to the board under test;

[0041] The software module is connected to the board under test through the TCP / IP protocol, and the board under test is respectively connected to the acquisition module and the signal display module, and the acquisition module caches the acquired data in the board under test through a coaxial cable, and transmits the data to the software module for processing;

[0042] The software module is provided with two groups and includes detection software 1 and detection software 2. The detection software 1 is connected to the acquisition module through the board under test, and the detection software 2 is connected to the signal display module through the board under test.

[0043] Furthermore, the board under test receives commands from the software module via FPGA.

[0044] Furthermore, the signal display module is provided with an LED indicator light, and the change of the path voltage is displayed by turning on or off the LED indicator light.

[0045] Furthermore, the acquisition module includes a charge coupler and a CCD conversion board. The charge coupler performs photoelectric conversion, and the obtained electrical signal is amplified by the CCD conversion board.

[0046] A CCD integrated acquisition board detection method comprises the following steps:

[0047] Step 1: Connect the acquisition module and the power supply module to the board under test respectively, ensure that the data connection and power supply are normal, and connect the board under test to the host computer software module;

[0048] Further, in step 1, the power supply module provides power supply that matches the working voltage to the board under test, and the power supply module includes a switching power supply. When the power indicator light of the switching power supply is normal, the power supply of the board under test is normal;

[0049] When the power indicator of the switching power supply flashes, the board under test is short-circuited and the voltage chip will quickly dissipate a lot of heat. The temperature measuring gun is used to accurately locate the heating part and determine whether the no-load output of the power chip is normal.

[0050] The no-load output of the power chip is abnormal, and the power chip should be replaced;

[0051] If the power chip outputs normally when not loaded, it is confirmed that the load part is short-circuited and the abnormal part should be replaced.

[0052] Step 2: The software module is connected to the board under test through the network port;

[0053] Furthermore, in step 2, the board under test is provided with 5 LED indicator lights, and the software module is connected to the network port of the board under test. When 2 LED indicator lights of the board under test are always on and 3 LED indicator lights flash alternately, it indicates that the program in the FPGA of the board under test is successfully burned. If only one LED indicator light flashes, it indicates that the program burning is abnormal.

[0054] Step 3, the software module includes detection software 1 and detection software 2, and the detection software 1 and the detection software 2 respectively control the program running in the FPGA on the board under test through transmission signals;

[0055] Furthermore, in step 3, the detection software 1 is opened. If the network is displayed as normal, it indicates that the connection with the board under test has been successfully completed.

[0056] If the network is abnormal:

[0057] When the indicator light is normal, confirm whether the network address of the upper computer software module has been modified;

[0058] When the two constant-on indicators are off, check whether the network cable is properly plugged in;

[0059] When the two indicator lights are normally on, but cannot connect to the host computer software module, and the indicator lights do not flash, it indicates that the relevant resistance is abnormal.

[0060] Step 4: The signal display module displays the signal through the LED indicator light; the acquisition module converts and amplifies the photoelectric signal and then transmits it back to the detection software 1.

[0061] Furthermore, in step 4, the acquisition module includes a charge coupler and a CCD conversion board. The detection software 1 controls the program running in the FPGA on the board under test by transmitting signals through the network port. The charge coupler performs photoelectric conversion and amplifies the converted electrical signal through the CCD conversion board. The amplified signal is transmitted to the board under test through a coaxial cable for data caching, and the data is transmitted back to the detection software 1 through the network port.

[0062] In addition, the network connection must be normal, and the detection software 1 can control the board under test. Multiple automatic detection means that the detection software 1 sends three commands to the board under test: wait for one command to be executed before proceeding to the next one.

[0063] Furthermore, the signal amplified by the CCD conversion board is the voltage of the charge coupler when there is no exposure, and its voltage range should be 1.5-3.5V. In actual use, the signal amplified by the CCD conversion board is transmitted to the board under test through a coaxial cable, and the voltage range of this transmission should be between 0.4-1.67. If it is not within this range, it means that there is a problem with the CCD conversion board or the charge coupler output. At this time, the data obtained in the software is incorrect, which means that the board under test is not faulty, but the charge coupler or CCD conversion board is broken.

[0064] Further, in step 4, the signal display module includes an LED light board, and the detection software 2 controls the program running in the FPGA on the board under test by transmitting signals through the network port, and determines whether the board under test responds correctly to the software operation by turning on and off the LED light board;

[0065] When the level is high, the LED light board is on; when the level is low, the LED light board is off.

[0066] The above embodiments are only specific implementation methods of the present invention, which are used to illustrate the technical solutions of the present invention rather than to limit them. The protection scope of the present invention is not limited thereto.
