[0006] The camera power supply is tested for functions such as the output voltage of silicon bridges AB1 to AB12, the output voltage of the voltage regulator N1, the DC voltages such as +24VR and +24VDM, and the aperture drive control.
[0007] There are many types and large quantities, so a fast detection method is needed to provide reliable detection parameters and diagnostic data for relay-level and base-level maintenance of electronic optical systems. Summary of the invention
[0008] The purpose of the present invention is to provide a detection device and method for an electronic optical system, so as to realize rapid detection of the electronic optical system and provide reliable detection parameters and diagnostic data for subsequent maintenance.
[0009] The object of the present invention is achieved by the following technical means: a detection device for an electronic optical system, comprising:
[0010] Detection command input module, used to input detection command signals:
[0011] A detection instruction control module is electrically connected to the detection instruction input module and is used to convert the input detection instruction signal into a recognizable signal of the camera of the electronic optical system to be detected, and then send it to the camera for execution of detection;
[0012] A monitor module is connected to a monitor of the electronic optical system to be detected and reads a detection instruction signal received by the monitor;
[0013] The camera module is connected to the camera of the electronic optical system to be detected, and reads the detection command signal received by the camera, and then executes the response signal after the detection action;
[0014] The detection module is electrically connected to the detection instruction control module, the monitor module and the camera module, receives the detection instruction signal sent by the detection instruction control module and read by the monitor module, and determines whether the detection instruction is issued;
[0015] Receive the detection command signal sent by the detection command control module and the response signal of the camera module, and determine whether the camera responds to the detection command.
[0016] It also includes a display module, which is connected to the detection instruction input module and is used to display the detection instruction input by the detection instruction input module.
[0017] It also includes a power detection module, which is connected to the electronic optical system to be detected and the detection module, reads the voltage data of the electronic optical system to be detected and sends it to the detection module for detection.
[0018] A detection method for an electronic optical system comprises the following steps:
[0019] Detection instruction input: input the instruction to be detected through the detection instruction input module;
[0020] Input command conversion: the detection command control module converts the input command into a signal recognizable by the camera of the electronic optical system to be detected, and sends it to the detection module and the camera;
[0021] The detection instruction is sent to detect that the monitor module reads the detection instruction received by the monitor from the monitor of the electronic optical system to be detected. If the detection instruction of the monitor is the same as the detection instruction of the detection module, it means that the inspection instruction can be sent normally, otherwise it means that the detection instruction cannot be sent to the camera;
[0022] In response to instruction detection, the camera module reads data from the camera of the electronic optical system to be detected, and sends the data to the detection module to detect the change value in the response instruction. If the item corresponding to the change value is consistent with the item corresponding to the sent detection instruction, it is considered that normal detection is possible, otherwise it means that normal detection is not possible.
[0023] The input instruction conversion is specifically as follows: a serial number and one or more bits in the serial data are assigned to the item corresponding to each detection instruction, and all items are arranged in a fixed order to form complete serial data. When the serial number of the input detection instruction is detected, the position of the item corresponding to the serial number in the serial data is changed, and the complete serial data is sent to the detection module and the camera.
[0024] Reading the detection instruction received by the monitor from the monitor of the electronic optical system to be detected is specifically to extract the line and field synchronization signals and 24-bit uplink serial data from the monitor detection socket, convert and output them into parallel data, and output them to the detection module after being latched by the latch.
[0025] Reading data from the camera of the electronic optical system to be detected specifically involves extracting the line and field synchronization signals and 24-bit downstream serial data from the camera detection socket, converting and outputting them into parallel data, and then outputting them to the detection module after being latched by the latch.
[0026] It also includes camera power detection. The power detection module reads various voltage data of the camera and determines whether the voltage is within the normal range through the detection module.
[0027] The latch is 54LS75.
[0028] The serial data is converted into parallel data by shift register 54LS165.
[0029] The beneficial effects of the present invention are as follows: through the detection device, the detection input, the detection items, and the serial data are linked and corresponded, the electronic optical system and the detection module are interconnected, the red and yellow filter response, zoom response, ranging possibility and other functions and performances of the camera combination are detected and a fault judgment is made; the red and yellow filter instructions, zoom instructions, focus instructions, ranging instructions and other functions and performances of the monitor combination are detected and a fault judgment is made; the keyboard input instructions and the display module output the detection results, the function and performance of the electronic optical system are detected and a fault judgment is made; the output voltages of the camera power supply combination are detected and a fault judgment is made.

[0039] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. DETAILED DESCRIPTION
[0040] like Figure 1 and Figure 8 As shown, a detection device of an electronic optical system includes:
[0041] like Figure 5 As shown, the detection instruction input module is used to input the detection instruction signal:
[0042] The detection command input module includes a keyboard input with a total of 24 keys, 16 of which are numeric keys and 8 are function keys. For example, the distance measurement command sent is: 8002MEM 40NEXT; the command is input through 16 numeric and function keys, and the keys are connected to the detection command control module, which is a conventional keyboard input circuit.
[0043] like Figure 4 As shown, the detection instruction control module is electrically connected to the detection instruction input module, and is used to convert the input detection instruction signal into a recognizable signal of the camera of the electronic optical system to be detected, and then send it to the camera to perform detection;
[0044] like Figure 4 As shown in the figure, the signal input by the detection command input module is output to the 8279 chip through 54LS154 (4-line to 16-line decoder) and 74LS138 (3-line to 8-line decoder). The 8279 chip is a universal programmable keyboard and display interface device, which has two functions: keyboard input and display output. When inputting from the keyboard, it provides automatic scanning, can be connected to the keyboard matrix, and receive input information; when displaying output, it is displayed by an 8-bit LED digital tube, that is, a display module, through automatic scanning.
[0045] Keyboard input can refer to the manual of the electronic optical system. There will be corresponding detection numbers for zoom control, focus control, red and yellow filter control, ranging instructions, line column display, additional gate and tracking gate, contrast, memory function, etc.
[0046] Some buttons with commonly used functions are also added to replace the key input. Their working principle is the same as that of the key, which is to correspond the button input, the signal received by the detection instruction control module, and the position in the serial data. An LED indicator light is also added. When there is a response, it is green, and when there is no response, it is red, so as to conveniently display the test results.
[0047] like Figure 3 As shown, the monitor module is connected to the monitor of the electronic optical system to be detected, and reads the detection instruction signal received by the monitor;
[0048] like Figure 2 As shown, the camera module is connected to the camera of the electronic optical system to be detected, and after reading the detection command signal received by the camera, it executes the response signal after the detection action;
[0049] The monitor module and the camera module have the same structure. They both extract the line and field synchronization signals and 24-bit serial data (DATA) from the monitor or camera detection socket. After being driven by the receiving chip 54115, they are sent to the shift register 54LS165 to be converted into parallel data, and then output to the detection platform after the signal is latched by the latch 54LS75.
[0050] The detection module is electrically connected to the detection instruction control module, the monitor module and the camera module, receives the detection instruction signal sent by the detection instruction control module and read by the monitor module, and determines whether the detection instruction is issued;
[0051] The monitor module and the camera module are also connected to an external device such as a computer, and the detection results are displayed on the computer display screen through a program.
[0052] Receive the detection command signal sent by the detection command control module and the response signal of the camera module, and determine whether the camera responds to the detection command.
[0053] The detection results can also be directly synthesized with the original image of the camera and then displayed on the monitor.
[0054] like Figure 6 As shown, it also includes a display module, which is connected to the detection instruction input module and is used to display the detection instruction input by the detection instruction input module.
[0055] The display module is composed of 8 digital light-emitting diodes (eight segments of common cathode), which display the instructions input by the keyboard through the 8279 chip. The 8-bit display module is composed of 8 bit buses and 8 segment buses. It is driven by the segment bus and the bit bus, and the detection results of the electronic optical system function test and debugging items are displayed through keyboard input instructions.
[0056] For example, when inputting a command, 8002 is displayed, so that the tester can see whether the command he input is correct, and when the response is normal, the test result is displayed.
[0057] It also includes a power detection module, which is connected to the electronic optical system to be detected and the detection module, reads the voltage data of the electronic optical system to be detected and sends it to the detection module for detection.
[0058] The required test voltage is extracted through the camera power test socket. The computer detection platform tests whether the amplitude of each voltage of the camera power combination is normal through the voltage signal extracted by the detection device, and determines the fault of each test voltage related component.
[0059] like Figure 7 As shown, the detection instruction input module and the display module are integrated on the panel, as well as the connection ports between other internal modules and the electronic optical system. The entire detection device is connected to the electronic optical system through a cable to read data from the electronic optical system and write data.
[0060] A detection method for an electronic optical system comprises the following steps:
[0061] Detection instruction input: input the instruction to be detected through the detection instruction input module;
[0062] First, the items to be tested are numbered. Each instruction, i.e., the test item, corresponds to a number, so that the test instructions correspond to the numbers.
[0063] For example, if the zoom response number is 1, through programming, the tester inputs 1 through the detection instruction input module, and the detection instruction control module can know that the zoom response test is being performed this time.
[0064] like Figure 7 As shown, the number can be input by pressing a key, or a button like a red filter or a yellow filter can be used to send a command to the detection command control module.
[0065] Input command conversion: the detection command control module converts the input command into a signal recognizable by the camera of the electronic optical system to be detected, and sends it to the detection module and the camera;
[0066] The input instruction conversion is specifically as follows: a serial number and one or more bits in the serial data are assigned to the item corresponding to each detection instruction, and all items are arranged in a fixed order to form complete serial data. When the serial number of the input detection instruction is detected, the position of the item corresponding to the serial number in the serial data is changed, and the complete serial data is sent to the detection module and the camera.
[0067] The detection instruction control module converts the input detection instruction into serial data that can be recognized by the detection module and the camera and sends it.
[0068] Specifically, each instruction corresponds to one or more bits of data at a fixed position in the serial data. For example, the zoom response, red filter, and yellow filter are numbered 1, 2, and 3, and their positions in the serial data are the first, second, and third bits. When testing the zoom response, input 1. After the detection instruction control module detects it, it changes the data in the first bit of the serial data and sends it out. For example, it outputs 0 when not detecting and outputs 1 when detecting. In this case, it outputs 100. The second and third bits are not detected, and the first bit is detected. The first bit corresponds to the zoom response, and the electronic optical system zooms after receiving the data of 100.
[0069] Test items that occupy multiple bits, such as gear, have a total of four gears, represented by 00-11. The gear item is located at the fourth and fifth bits of the serial data. When it is 11, it means switching to the fourth gear.
[0070] Furthermore, the serial data output by the detection instruction control module is sent to the controller of the electronic optical system. After receiving the instruction, the controller of the electronic optical system controls the camera to zoom.
[0071] The detection instruction is sent to detect that the monitor module reads the detection instruction received by the monitor from the monitor of the electronic optical system to be detected. If the detection instruction of the monitor is the same as the detection instruction of the detection module, it means that the inspection instruction can be sent normally, otherwise it means that the detection instruction cannot be sent to the camera;
[0072] Reading the detection instruction received by the monitor from the monitor of the electronic optical system to be detected is specifically to extract the line and field synchronization signals and 24-bit uplink serial data from the monitor detection socket, convert and output them into parallel data, and output them to the detection module after being latched by the latch.
[0073] This step is to detect whether the detection instruction has been sent to the electronic optical system.
[0074] like Fig. 9As shown, the line and field synchronization signals and 24-bit uplink serial data (DATA) are extracted from the monitor detection socket, and sent to the shift register 54LS165 (i.e., the 24-bit serial-in parallel-out circuit converts the serial data into parallel data output) after passing through the receiving chip 54115, and then the data is latched. The chip outputs parallel data, mainly including uplink pulse signals such as red and yellow filter instructions, zoom instructions, ranging instructions, and focusing instructions, which are latched by the latch 54LS75 signal and output to the detection module; at the same time, the DC voltage +15V and +5V are extracted from the monitor detection socket and output to the detection module for detection.
[0075] The latch is 54LS75.
[0076] The serial data is converted into parallel data by shift register 54LS165.
[0077] The serial data is converted into parallel data, and each bit of data enters the latch and is output to the detection module.
[0078] Specifically, the serial data is split in sequence, each latch receives data at a fixed position, and the pin also outputs data at a fixed position, so that each pin of each latch can correspond to the instruction of a detection item.
[0079] For example, latch 1 receives the first 8 bits of data, and the first to eighth pins output the first to eighth bits of data in sequence, then the first pin of latch 1 outputs the zoom response instruction, and the rest are similar.
[0080] After receiving the data from the latch, the detection platform compares it one by one with the detection instruction sent. If they are completely consistent, it means that the electronic optical system has received the detection instruction.
[0081] Alternatively, after the detection platform receives and identifies which item is to be detected by the detection instruction, it only compares the output of the latch pin corresponding to the item and no longer compares others.
[0082] In response to instruction detection, the camera module reads data from the camera of the electronic optical system to be detected, and sends the data to the detection module to detect the change value in the response instruction. If the item corresponding to the change value is consistent with the item corresponding to the sent detection instruction, it is considered that normal detection is possible, otherwise it means that normal detection is not possible.
[0083] Reading data from the camera of the electronic optical system to be detected specifically involves extracting the line and field synchronization signals and 24-bit downstream serial data from the camera detection socket, converting and outputting them into parallel data, and then outputting them to the detection module after being latched by the latch.
[0084] The response instruction is similar to the control instruction. The specific device will act after receiving the control instruction, and its value will change. The same serial data is used, and an instruction is specified for each or multiple positions so that the pin output of each latch can correspond to the detection instruction.
[0085] like Fig. 9 As shown, the line and field synchronization signals and 24-bit downstream serial data (DATA) are extracted from the camera detection socket, and are sent to the shift register 54LS165 (i.e., a 24-bit serial-in-parallel-out circuit, which converts the serial data into parallel data output) for serial-to-parallel conversion after being driven by the receiving chip 54115, and then the data is latched. The chip outputs various types of parallel data, mainly including zoom response, solar shutter response, ranging response, red and yellow filter response and other downstream pulse signals, which are output to the computer integrated detection platform after being latched by the latch 54LS75 signal; at the same time, the DC voltages ±15V, +24V, +12V, and +5V are extracted from the camera detection socket and output to the computer integrated detection platform for detection.
[0086] When the data at a certain position changes before and after the detection, it can be determined that the device corresponding to this position has responded. Compared with the device corresponding to the detection instruction, if they are consistent, it means that the device responds normally.
[0087] It also includes camera power detection. The power detection module reads various voltage data of the camera and determines whether the voltage is within the normal range through the detection module.
[0088] The power supply detection directly reads the voltage information from the camera power socket of the electronic optical system to realize the detection of the output voltage of the combined silicon bridge AB1 to AB12, the output voltage of the regulator, the aperture drive control and other functions, including +5V, +10.5V, +21.5V, -21.5V, +27V, +6.7V, +28V, +9V, +12V and variable voltage output detection.
