[0044] The out-cabin lighting control box is connected to various lighting devices (such as landing lights, navigation lights, rescue lights, etc.) outside the aircraft through cables. These devices turn on, off, or adjust the brightness according to the instructions from the control box.

[0045] The in-cabin and out-cabin lighting control boxes may support multiple control methods, such as manual control, automatic control, and remote control. Manual control is usually achieved through buttons or knobs on the control box; automatic control adjusts the working state of the lighting devices according to the flight state of the aircraft or the external environment; remote control allows the pilot to control the airport lights through ground-air communication equipment. For lighting devices that support dimming, the control box can adjust their brightness by changing the size of the supplied voltage or current.

[0046] The working principle of the in-cabin and out-cabin lighting control boxes is as shown in Figure 2

[0047] The lighting control box has complex circuit board components such as input / output modules, CPU modules, light guide control modules, power modules, and motherboard modules. The control box receives 115V / 400Hz AC signals from the AC power system and 28V DC signals from the DC power system through the input module, performs power regulation control and logic judgment through the CPU module, and controls the lighting power signal output to the corresponding lighting devices in the aircraft cabin, such as the instrument panel, control panel, and floodlight, through the output module.

[0048] ​The lighting power is provided by the on-board power supply 115V, and the power module in the on-board lighting control box first converts 115V into 28V, and then sends it to the adjustable transformer on each control board (adjusting brightness), which outputs 0-28V to the off-board column lamp, and at the same time, the adjustable transformer outputs 0-28V to the next stage transformer in the lighting power supply box, which outputs 0-5V to the internal lighting and light guide plate lighting of the device, and the brightness adjustment can be adjusted by the on-board illuminance sensor input to the control box signal, and each part of the lighting switch can be controlled by the manual press switch and rotary switch on the control box.

[0049] On-board lighting control box

[0050] According to the statistical analysis of the test requirements and verification process procedures of the on-board lighting control box, the tester should provide a digital multimeter to test the "closed / open" state of the internal switch, an 8-way switch switching module to automatically switch the pins of the on-board lighting control box connector to the test end of the digital multimeter, a program-controlled DC power supply to provide working power for the on-board lighting control box, and a 2-channel analog output module to simulate the output signal of the on-board illuminance sensor.

[0052] According to the analysis of the principle of the off-board lighting control box and the verification process procedures, the off-board lighting control box verification mainly includes landing light control function check and rescue light control function check, the tester should provide a digital multimeter to test the "closed / open" state of the internal switch, an 8-way switch switching module to automatically switch the pins of the off-board lighting control box connector to the test end of the digital multimeter, a program-controlled DC power supply to provide working power for the off-board lighting control box, and a 2-channel analog output module to simulate the output signal of the on-board illuminance sensor.

[0053] The helicopter landing light can provide illumination from the approach to the landing site to the entire stage of landing and taxiing for the night navigation of the helicopter. The control of the landing light includes landing light on / off, retraction / deployment, left rotation / right rotation, normal / infrared control mode, etc. The working cross-linking principle of the landing light is as shown in Figure 3

[0054] According to the analysis of the landing light function and the verification process procedures, a program-controlled DC power supply is needed to provide the landing light working and simulated control signal during the landing light test process, and a switch module with a total of 8 channels is needed to input the state of the simulated control signal.

[0055] The alarm control box is mainly composed of a power supply part (a voltage stabilizing power supply circuit and a voltage regulating power supply circuit), an input part (a collection circuit), a control part (an input buffer interface circuit, a microcomputer circuit, and an output buffer interface circuit), and an output part (a driving circuit), and its principle diagram is as​Figure 4 as shown:

[0056] The warning control lamp box collects fault signals output by each subsystem of the aircraft, analyzes and processes them, and displays warning information on each warning lamp box. It controls the output signals to make the corresponding signal lights and main warning lights light up, go out, or flash. The multi-channel fault signals (positive or negative control fault signals) output by each system on the aircraft are sent to the warning control box through the signal collection circuit. The internal microprocessor of the warning control box analyzes and processes the signals. If a fault occurs, the corresponding lamp box signal light is lit according to the warning processing logic corresponding to the fault of different levels.

[0057] 1) Power-on self-test function: After power-on, all signal lights are lit for 0.5s and then all go out, indicating that the system self-test is passed and enters the normal working state. When there is no external fault signal input, the system is in a waiting working state and all signal lights are not lit.

[0058] 2) Warning function: When the fault signals from each subsystem on the aircraft are valid, the warning control box controls the corresponding lamp box signal light to light up or flash according to the danger level of the input fault signal.

[0059] 3) Self-test function: When the test light button is pressed, all signal lights flash or light up; when the test light button is released, all signal lights go out.

[0060] 4) Day-night conversion / brightness adjustment function: The brightness of the warning lamp box can be adjusted.

[0061] According to the analysis of the functions of the warning control lamp box and the verification process procedure, a program-controlled DC power supply is required to provide working and simulation control signals for the warning control lamp box during the warning control lamp box test process. A total of 25 switch modules of "ground / on" and "28V / on" signal types are simulated.

[0062] The helicopter prompt lamp box is part of the helicopter's onboard electronic equipment, used to control and manage various light signal systems on the helicopter, including warning lights, status indicator lights, etc., to provide key operational information and status feedback to the pilot.

[0063] The prompt lamp box receives signals from various systems of the helicopter through internal circuits, such as engine status, hydraulic system pressure, electrical system voltage, etc., and processes the received signals. According to the preset logic and threshold, it judges the current working state of the helicopter and whether there are potential problems. According to the processed signals, the prompt lamp box controls the corresponding lights to light up or go out to convey the current state of the helicopter to the pilot.

[0064] The prompt light box is usually integrated with other onboard electronic devices such as the automatic pilot system, flight data recording system, etc. of the helicopter to realize information sharing and collaborative work. Through specific communication protocols and interfaces, data exchange and instruction transmission are carried out with other systems. The internal principle of the prompt light box is as shown in Figure 5

[0065] According to the analysis of the functions of the prompt light box and the verification process procedure, a program-controlled DC power supply is needed to provide working and simulation control signals of the prompt light box during the test of the prompt light box, and a total of 20 switch modules of the type of simulation "ground / on" and "28V / on" signals.

[0066] Through the analysis of the detection process procedures of the inboard lighting control box, outboard lighting control box, landing light, warning control light box and prompt light box and the previous technical exchanges, according to the types of detection signals, the detection signals and required test resources can be divided into the following categories:

[0067] A total of 8 analog output modules are needed: 4 for the inboard lighting control box and 4 for the outboard lighting control box.

[0068] Power supply range: 0-30VDC adjustable, 0-40A output capacity.

[0069] 1 digital multimeter: can be used for continuity test.

[0070] The industrial computer is the control center of the entire test system, which mainly allocates various test resources of the system to achieve the test purpose.

[0071] The industrial computer controls the channels on the relay board cards in the interface adapter box through the LAN bus, controls the program-controlled power supply and switch module using the LAN bus communication, and controls the digital multimeter based on the USB bus to realize the continuity test.

[0072] The interface adapter box contains 3 switch modules and a splitter. The switch module is mainly composed of a program-controlled relay, which is an important part of the test system. It mainly controls and switches the system test resources flexibly according to the corresponding test requirements, and the splitter transmits the measurement signals and control signals of the test system to the product under test.

[0073] The tester is designed according to the actual functions and working principles of the on-board lighting and warning products. Its test functions mainly include: 1. can simulate the illuminance sensor signal; 2. can control the landing light to perform (collect, release and rotate) actions; 3. can simulate the warning signal; 4. can measure the intensity of the output brightness control signal. The test principles for various products under test are described in detail as follows:

[0074] ​The in-cabin and out-of-cabin lighting control boxes differ in the controlled on-board light illuminating components, but according to the requirement analysis, the main test contents are the effectiveness of the switch devices arranged on the control boxes, i.e. conducting test.

[0075] The switch devices in the control boxes are switched at both ends through the pin of the electrical connector, and the on-off of the switch can control the lower-level executive components, and the test principle is as shown in Figure 6

[0076] The in-cabin and out-of-cabin lighting control boxes respectively integrate a plurality of switch assemblies, such as emergency exit switch, day / night conversion switch, emergency light switch, rescue light switch, etc., and the two ends of the switch can be connected to external components through the pin of the electrical connection interface of the control box. The switch module is distributed with multiple program-controlled switches, which are divided into two groups: the digital multimeter HI test group, which connects the A end of n program-controlled switches to the digital multimeter HI interface; the other group is the digital multimeter LO test group, which connects the A end of n program-controlled switches to the digital multimeter LO interface. The B end of the 2n program-controlled switches is connected to the pins of the power control board. At this time, the program-controlled switches in the HI and LO test groups can be closed to realize communication with the digital multimeter, so as to conduct conducting test.

[0077] The landing light test content is mainly to simulate the "28V / ON" control signal input to the landing light, and observe whether the landing light action meets the control requirements. The test principle is as shown in Figure 7

[0078] The industrial computer controls the program-controlled DC power output 28V and GND voltage to the switch module through the LAN port, and according to the landing light test requirement, the A end of the 9 program-controlled relay contacts of the switch module is connected to the 28V line of the program-controlled power output, and the B end is connected to the 9 pins of the landing light electrical connection port; the A end of the 2 program-controlled relay contacts of the switch module is connected to the GND line of the program-controlled power output, and the B end is connected to the 2 pins of the landing light electrical connection port. When starting the test, the industrial computer controls the corresponding channel of the switch module to close, so as to transmit the 28V or GND signal to the landing light pin. For example, if the light power is turned on, the industrial computer controls the switch module CH2 and CH10 to close at the same time.

[0079] The warning control light box can receive the working state of other components and output 28V or ground signal to the corresponding array pin according to the received signal, so as to realize the bright and dark control of the warning light. The test principle of the warning control light box is as shown in Figure 8

[0080] ​​​The alarm control lamp box receives signal types including 28V / ON, ground / ON, etc. During testing, the 28V and GND are output by the programmable DC power supply controlled by the industrial computer, and are connected to the collection pins of the electrical connection port of the alarm control lamp box through the programmable relays in the switch module. There are several programmable relays connected to the 28V and GND, respectively, and the industrial computer can remotely control the closing / opening of a single relay. After the alarm control lamp box receives the instructions and processes them internally, corresponding instructions are output to the lower components. At this time, the output pins of the control box are connected to the discrete quantity collection card configured in the system, and when the 28V / ON or ground / ON signal is output, it can be collected by the card. After the lamp box receives the relevant signal, the corresponding status indicator light becomes brighter, and at this time the camera can capture the indicator light image and transmit it to the image recognition module of the software to analyze the on / off state of the lamp and serve as the basis for determining the test qualification.

[0081] The prompt lamp box can receive the working state of other components and control the on / off of the prompt lamp according to the received signal. The test principle of the prompt lamp box is as shown in Figure 9

[0082] The prompt lamp box receives signal types including 28V / ON, ground / ON, etc. During testing, the 28V and GND are output by the programmable DC power supply controlled by the industrial computer, and are connected to the collection pins of the electrical connection port of the alarm control lamp box through the programmable relays in the switch module. There are several programmable relays connected to the 28V and GND, respectively, and the industrial computer can remotely control the closing / opening of a single relay.

At this time, the output pins of the control box are connected to the discrete quantity collection card configured in the system, and when the 28V / ON or ground / ON signal is output, it can be collected by the card. After the lamp box receives the relevant signal, the corresponding status indicator light becomes brighter, and at this time the camera can capture the indicator light image and transmit it to the image recognition module of the software to analyze the on / off state of the lamp and serve as the basis for determining the test qualification.

[0097] 5. Complete the interface with the product under test and adapt to different signal type testing requirements of each pin
