Technical Field
[0001] This utility model relates to the field of airport lighting equipment technology, and in particular to a lamp simulation load tooling. Background Technology
[0002] The lighting control system on an aircraft runway is a critical piece of equipment ensuring the safe takeoff and landing of aircraft at night or in low visibility conditions. These lights include end lights, centerline lights, and edge lights. Their operational status directly affects aircraft safety, therefore, the testing of the lighting control system is of paramount importance.
[0003] Existing testing methods for lighting control systems require all lighting fixtures to be used as test equipment. Open circuit faults are tested by disconnecting the lighting fixture connectors, short circuit faults are tested by shorting the circuits in the lighting fixture connectors, and the lighting fixture current is tested for each test cable using a clamp meter.
[0004] Existing testing methods for lighting control systems typically require all lighting fixtures to be used as auxiliary testing equipment in order to drive all fixtures and detect their fault conditions. This method has the following drawbacks:
[0005] a) Testing costs are high, and a large debugging space is required;
[0006] b) Insufficient testing: Each luminaire has multiple light source boards. Disconnecting the connectors simultaneously disconnects the power to multiple light sources, making it impossible to perform accurate fault diagnosis for individual luminaires.
[0007] c) Testing the current is inconvenient and takes a long time.
[0008] Therefore, developing a small, portable, scalable, controllable, and testable lamp simulation load fixture to meet the testing needs of lamp control systems has become an urgent technical problem to be solved. Utility Model Content

[0040] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.
[0041] The principles and features of this utility model are described below with reference to the accompanying drawings. The embodiments described are only for explaining this utility model and are not intended to limit the scope of this utility model. The following description, in conjunction with... Figure 1-8 The preferred embodiments of this utility model will be described in further detail below:
[0042] like Figure 1-8 As shown, this utility model embodiment provides a lamp simulation load fixture, including:
[0043] Tooling frame 7, which includes a multi-layer load-bearing support composed of support columns 8, support beams 9 and pallets 10;
[0044] Several lamps are arranged on the support plate 10;
[0045] A multi-functional control panel 14 is fixed on the fixture frame 7. Multiple wires are arranged inside the control panel. One end of each wire is connected to a lamp, and the other end is connected to a test cable 6 via a connector. The test cable 6 is connected to the lighting control system via a connector. The multi-functional control panel 14 also has a toggle switch 15 and a current test hole 16 corresponding to each wire. The toggle switch 15 has three positions, which can be adjusted to allow the corresponding wire to be in normal, open-circuit, and short-circuit states, respectively, i.e., to achieve the corresponding lamp being on, off, and short-circuited. The current test hole 16 is used to connect instruments to test the current of the corresponding lamp. The current test hole 16 adopts a banana plug form. The multi-functional control panel 14 has a current test hole 16 for each light source lamp, and the state of the driving current of the lamp driver box 3 can be determined by measuring the current of each light source.
[0046] In one embodiment, the connector includes an aviation socket 4 and an aviation plug 5. The aviation plug 5 is correspondingly disposed at both ends of the test cable 6, and the aviation socket 4 is correspondingly disposed on the multi-function control panel 14 and the lamp driver box 3 of the lighting control system. One end of the test cable 6 connected to the multi-function control panel 14 is a single integrated aviation plug 5, and the other end is a plurality of non-integrated aviation plugs 5 that match the aviation socket 4 on the lamp driver box 3. All lamp driver boxes 3 are connected through the test cable 6. Different working states (normal, open circuit, and short circuit) of the lamps are adjusted by the toggle switch 15 on the multi-function control panel 14. Since the aviation plug 4 at the lamp driver box 3 is a universal socket in the industry, this section of the multi-branch test cable 6 needs to be adapted to install a universal plug (such as a 4-pin plug). In order to integrate the design of the test cable 6 and avoid the problem of excessive number of cables causing tangling and knotting, the other end of a single test cable 6 is designed as a single integrated plug, and an integrated socket (such as a 12-pin socket and a 32-pin socket) is correspondingly disposed on the multi-function control panel 14.
[0047] In one embodiment, one end of each wire inside the multi-functional control panel 14 that connects to the lamp is set as a terminal block 17. The lamp is connected to the terminal block 17. In this way, the wires between the terminal block 17 and the multi-functional control panel 14 can be arranged and fixed in advance to avoid messy wiring. At the same time, it also facilitates the expansion of the number of lamps and wiring operations.
[0048] In one embodiment, the lamp is configured as a light source board 13, on which a plurality of lamp beads 18 are integrated. The light source board 13 is used to simulate an actual lamp. In one embodiment, two types of light source boards 13 are provided, and the specific parameters of the two types of light source boards 13 are as follows.
[0049] D-type light source board 13 (e.g.) Figure 7 (As shown): 12 LEDs of the same specification are mounted on the board. Three LEDs are connected in parallel to simulate one light source. Each D-type light source board simulates two end lights. 12 boards are required.
[0050] Z-type light source board 13 (e.g.) Figure 8 As shown): Simulates centerline and edge lights, with 10 LEDs on the board, each simulating one light source, requiring 9 boards.
[0051] In one embodiment, the tooling frame 7 includes a multi-layer load-bearing support structure composed of support columns 8, support beams 9, trays 10, and casters 11. The casters 11 are installed at the bottom of the support columns 8, allowing the tooling to move and be fixed in any direction, enabling debugging work in different environments. The trays 10 are placed on the support beams 9 and connected to the support beams 9 with screws, resulting in a stable and reliable structure that is easy to disassemble and replace. The tooling frame 7 is divided into four layers. The upper three trays 10 have sufficient space to install heat sinks 12 and light source boards 13, allowing for the installation and layout of heat sinks 12 and light source boards 13 according to different product functions. The bottom layer is used to place the debugging cable 6 from the tooling to the lamp driver box 3. This tooling has reserved toggle switches 15 and aviation plugs 5, and the light source boards 13 can be extended on other trays 10 to adapt to different lamp control equipment. It is an important carrier for carrying the light source boards 13, debugging cables 6, and other accessories.
[0052] In one embodiment, a heat sink 12 is provided on the tray 10, and the light source plate 13 is mounted on the heat sink 12. The heat sink 12 is made of aluminum, a material with high thermal conductivity, and has a thin and numerous sheet-like structure, which effectively increases the contact area with air and enhances the heat dissipation function. Excessive temperature will significantly reduce the lifespan and luminous efficiency of the LED beads 18 on the light source plate 13. By mounting the light source plate 13 on the heat sink 12, the heat generated by the light source plate 13 can be dissipated through the good thermal conductivity of the heat sink 12, effectively reducing the heat of the light source plate 13 and increasing the lifespan of the light source plate 13.
[0053] like Figures 3-6 As shown, the functional requirements of the toggle switch 15 are as follows:
[0054] The three-position toggle switch has three settings: the middle position is normally closed (meaning the light source is normally powered); the upper position is for short-circuit testing; and the lower position is for open circuit. Traditional toggle switches 15 have a normally open middle position. This cannot simulate the light source switching from a normal state to a short-circuit state in a single step. Other complex switch types are too bulky, and the multi-functional control panel 14 cannot accommodate a large number of switches. Therefore, a suitable toggle switch 15 needs to be selected.
[0055] This invention presents a special toggle switch 15 that overcomes the shortcomings of traditional toggle switches 15 and meets the requirements for switching the working states of simulated lighting fixtures. A schematic diagram of the control method of this toggle switch 15 is drawn based on its form; see [link / reference]. Figure 6 The toggle switch 15 has six contacts: A, B, C, D, E, and F. Contact A is connected to the positive terminal of the power supply, contact E is connected to the negative terminal of the power supply, contact B is connected in series with contact E, and contact A and contact D are connected by a wire. Contact A and contact B are connected to an external current test hole 16 through a wire. There are four moving contacts. The fixed ends of two moving contacts (moving contacts one and two) are connected to contact A, and the fixed ends of the other two moving contacts (moving contacts three and four) are connected to contact B.
[0056] When the toggle switch 15 is in the middle state (simulating the lamp circuit), the actuating end of the first moving contact is disconnected from the C contact, the actuating end of the second moving contact is connected to the B contact, the actuating end of the third moving contact is connected to the F contact, and the actuating segment of the fourth moving contact is disconnected from the E contact.
[0057] When the toggle switch 15 is in the upward position (simulating a short circuit in the lamp), the actuating end of the first moving contact is disconnected from the C contact, the actuating end of the second moving contact is connected to the B contact, the actuating end of the third moving contact is disconnected from the F contact, and the actuating segment of the fourth moving contact is connected to the E contact.
[0058] When the toggle switch 15 is in the downward position (simulating a broken circuit in the lamp), the actuating end of the first moving contact is connected to the C contact, the actuating end of the second moving contact is disconnected from the B contact, the actuating end of the third moving contact is connected to the F contact, and the actuating segment of the fourth moving contact is disconnected from the E contact.
[0059] By operating the toggle switches 15 on the multi-function control panel 14 corresponding to the lamps (up, middle, down), the short circuit, circuit, and open circuit of the light source board 13 in the simulated lamps can be achieved.
[0060] Use a multimeter in current mode to test the banana-shaped test hole on the multi-function control panel 14 to measure the current of the lamp.
[0061] By adding different light source boards 13 to the tray 10, the types and quantities of controllable lamps can be expanded.
[0062] After the lighting control system test is completed, disconnect the connector from one end of the fixture to the lighting control system, and store the test cable 6 on the first-layer tray 10 along the outlet below the multi-function control panel 14.
[0063] The lighting control system is connected to the connector on the multi-function control panel 14 via the debugging cable 6. The wires on the connector are connected to the light source board 13 through the current test hole 16, the toggle switch 15, and the terminal block 17. The toggle switch 15 on the multi-function control panel 14 can be operated to simulate a lamp malfunction, and the current of the lamp can be tested through the current test hole 16 to detect the magnitude of the output current of the lamp driver box and determine the state of the driving current of the lamp driver box 3.
[0064] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. The scope of protection of this utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this utility model within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this utility model.
