Description

Technical Field

[0001] This invention relates to the field of airport navigation lighting technology, specifically to an airport navigation lighting circuit troubleshooting training simulator. Background Technology

[0002] In airport navigation lighting professional skills training, the methods and modes of circuit troubleshooting training are still relatively simple. Most units build small simulated lighting circuits, which generally contain 20-30 light nodes and require a space of at least 50 square meters. The cost is relatively high. Taking 20 light nodes as an example, the cost of the main equipment that makes up the training site, including lamps, isolation transformers and cables, can reach 10,000 yuan. Moreover, they are basically set up outdoors, which is greatly affected by the weather, making them difficult to maintain and use.

[0003] Therefore, a training simulator for troubleshooting airport navigation lighting circuits has become an urgent problem to be solved. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an airport navigation light circuit troubleshooting training simulator, which is integrated and modular, can be placed indoors, occupies a small area, and can simulate any number of light position nodes for troubleshooting training as needed within the allowable range of the device.

[0005] To solve the above-mentioned technical problems, the technical solution provided by the present invention is: an airport navigation light circuit troubleshooting training simulator, including a main structure of the simulation circuit, a fault setting switch panel module and a lamp tube node station module;

[0006] The main structure of the analog circuit adopts several series-connected switch panel modules; the switch panel modules are connected to the CCR output terminals, and each switch panel module consists of several series-connected lamp position nodes and a double-position switch connected to the lamp position node; the fault setting switch panel module consists of several three-position switches, and each three-position switch is connected in series in the node terminal of the lamp position node; the lamp tube node station module consists of several lamp tubes, and the lamp tubes are connected to each double-position switch.

[0007] Furthermore, the switch panel module comprises five units connected in series.

[0008] Furthermore, each switch panel module contains 20 lamp position nodes, and each lamp position node can be disconnected to form two terminals.

[0009] Furthermore, the dual-position switch is a 6-pin dual-position switch, and the triple-position switch is a 6-pin triple-position switch.

[0010] Furthermore, a maximum of 20 three-position switches can be installed.

[0011] Furthermore, the lamp tube is provided in five groups.

[0012] The advantages of this invention compared to the prior art are:

[0013] The training simulator of this invention, through the coordinated work of multiple series-connected switch panel modules, fault setting switch panel modules, and lamp tube node workstation modules, can realistically simulate various operating conditions and fault situations of airport navigation lighting circuits, including faults such as short circuits, open circuits, and grounding, providing technicians with a comprehensive troubleshooting training environment.

[0014] The simulator of this invention is not limited by time and space, allowing technicians to conduct troubleshooting training anytime, anywhere, greatly improving training efficiency and flexibility. Simultaneously, the simulator can be set with multiple fault modes, enabling technicians to conduct multiple troubleshooting training sessions for different faults in a short period, deepening their understanding and mastery of fault phenomena and handling methods.

[0015] The simulator of this invention uses an independent simulation system that is completely isolated from the actual airport navigation lighting circuit, so it will not affect the normal operation of the airport and also ensures the training safety of technical personnel.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0024] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0025] The following is a detailed description of the airport navigation light circuit troubleshooting training simulator of the present invention, with reference to the accompanying drawings.

[0026] Working principle:

[0027] I. Troubleshooting Methods for Airport AC Series Lighting Circuits

[0028] This invention is mainly based on the troubleshooting principle of the AC series lighting circuit in airports. The circuit model of the lighting circuit after leaving the CCR (Central Control Room) is attached. Figure 1 As shown, the field circuit starting from the CCR output uses a single-core armored cable, and the primary side of the isolation transformer at the circuit node is connected in series with the cable. When there are high resistance (open circuit) and leakage current (grounding) faults in the circuit, it is necessary to disconnect the connection between the isolation transformer and the cable (with plug) during troubleshooting. That is, the circuit is disconnected at this node, the circuit is segmented, and then the faulty line can be identified.

[0029] II. Design Principles of the Training Simulator of the Invention

[0030] Based on the original design intent of the training simulator, and in order to reduce the space required and the amount of lamps, isolation transformers, and armored cables, and in conjunction with the troubleshooting method for AC series lighting circuits, the training simulator of this invention will utilize a one-click node selection function. This consolidates the nodes involved in the troubleshooting process, allowing for the selection and operation of disconnected nodes – a fundamental design principle. Selecting the node to be opened and operating at that location, represented by a one-click function, means that all nodes in the circuit can be operated at the same workstation. The basic model is shown in the attached figure. Figure 2 As shown.

[0031] Troubleshooting requires segmenting the circuit. Therefore, opening one node divides the circuit into two segments. In actual airport lighting circuit maintenance, it's often necessary to open at least three nodes simultaneously to determine the direction of the line problem. Therefore, [the following is an explanation of the process]. Figure 2 The workstations in the system require at least three. When the direction of the circuit is not considered, using the binary search method, the number of times a node is disconnected during maintenance will be affected by the number of nodes. Generally, the number of nodes in an airport lighting circuit is between 20 and 100. The number of switches installed as replacement nodes in each module of the simulator is equal to the number of nodes, but this number should not be excessive for simulation.

[0032] The number of times nodes are opened and segmented follows a certain pattern; generally, the more nodes there are, the more segmentations are required. During training, troubleshooting needs to be achieved using a binary search method. First, it's necessary to master the absolute binary search method. For example, when using a simulator in assessments, the number of times nodes are opened needs to be strictly recorded. The following are conclusions drawn from troubleshooting using a nearly equal binary search method with divisions of 1 / 2, 1 / 4, 1 / 8, 1 / 16…:

[0033] Assuming an open-circuit fault at one point in the loop, the number of nodes that need to be disconnected is:

[0034] 1. Taking a circuit with 40 lights as an example, after the first segmentation [(40-1) / 2], the number of lights at the two ends are 19 and 20 respectively; after the second segmentation, the number of lights at the two ends is 9 and 10 respectively; after the third segmentation, the number of lights at the two ends is 4 and 5 respectively; after the fourth segmentation, the number of lights at the two ends is 2 and 3 respectively; and after the fifth segmentation, the number of lights at the two ends is 1 and 1 respectively, which can determine the location of the fault.

[0035] 2. Taking a circuit with 50 lights as an example, the fault location can be determined by counting lights 24 and 25 in the first test, lights 15 and 15 in the second test, lights 5 and 6 in the third test, lights 2 and 3 in the fourth test, and lights 1 and 1 in the fifth test.

[0036] 3. Taking a circuit with 60 lights as an example, the first time is 29 and 30; the second time is 14 and 15; the third time is 7 and 8; the fourth time is 3 and 4; the fifth time is 1 and 2. At this point, the fault cannot be absolutely determined; the sixth time is 1 and 1. At this point, the fault can be absolutely found.

[0037] The training simulator of this invention can be set to a maximum of 5 workstations, i.e., 5 main modules. Based on the above characteristics, it was found that the key to determining whether the number of times a node is opened is 5 or 6 is the occurrence of 6 or fewer nodes in the third instance. The following formula shows that if 5 main modules are set, the value of the number of loop nodes Q should be 55 or less:

[0038]

[0039] Combined with appendix Figure 2-6 This invention will be described in detail below.

[0040] An airport navigation light circuit troubleshooting training simulator mainly includes a simulation circuit main structure, a fault setting switch panel module 1, and a lamp tube 6-node workstation module.

[0041] The main structure of the simulation circuit adopts several series-connected switch panel modules 1, which are connected to the CCR output terminals 2. In this invention, there are five switch panel modules 1 connected in series. This series structure can simulate the connection relationship of different areas in the actual airport navigation lighting circuit, making the training more closely resemble the actual situation.

[0042] Each switch panel module 1 consists of several lamp position nodes 3 connected in series and a double-position switch 4 connecting the lamp position nodes 3. Specifically, each switch panel module 1 contains 20 lamp position nodes 3, and each lamp position node 3 can be disconnected to form two terminals. This design allows each lamp position node 3 to be controlled independently, facilitating the simulation of lighting faults in different locations. The double-position switch 4 is a 6-pin double-position switch 4. By switching the different states of the double-position switch 4, the on / off state of the lamp position nodes 3 can be controlled, thereby simulating the on / off state of the lights.

[0043] The fault setting switch panel module 1 consists of several three-position switches 5, each of which is connected in series in the terminal block of the lamp position node 3. The three-position switches 5 are 6-pin switches, and a maximum of 20 can be configured. By setting the three-position switches 5 in different positions, various complex fault conditions can be simulated, such as short circuits, open circuits, and grounding faults, providing technicians with comprehensive fault diagnosis training.

[0044] The lamp tube 6 node workstation module consists of five sets of lamp tubes 6, which are connected to various double-position switches 4. The lamp tubes 6 are used to simulate actual airport navigation lights. Through the control of the double-position switches 4, the on / off status of the lights can be displayed intuitively, allowing technicians to clearly observe the effect of troubleshooting operations.

[0045] The specific implementation process of the airport navigation light circuit troubleshooting training simulator of the present invention is as follows:

[0046] The training simulator of this invention utilizes a switch-controlled node approach, employing the switch to simulate the switching of the primary side of the transformer, and allows for the setting of nodes to simulate open-circuit faults and ground faults. The circuit architecture of the training simulator of this invention is attached. Figure 3As shown, L1 and L2 are analog circuits with two CCR output terminals. If 20 lamp position nodes 3 are set, each lamp position node 3 can be disconnected into two node terminals. The node terminal names are, for example, 1, 1', 2, 2'...20, 20'. KA, KB, KC, KD, and KE are 6-pin dual-position switches 4 distributed on the five switch panel modules 1 of AE. Each switch panel module 1 is set with 20 of them. KG is a 6-pin 3-position switch of the fault setting switch panel module 1, which is connected in series in each node terminal. A maximum of 20 can be set.

[0047] LA1, LA2, LB1, LB2, LC1, LC2, LD1, LD2, LE1, LE2 are the wiring points for the five physical lamp holders 6. (See attached diagram) Figure 3 The circuit diagram consists of 20 groups, with node terminals connected to the corresponding pins on the terminal blocks.

[0048] The simulator of the present invention has 5 switch panel modules 1 corresponding to 5 physical lamp tubes 6. Each switch panel module 1 is equipped with 20 sets of dual-position switches 4, corresponding to 20 selectable lamp position nodes 3 of the circuit. The 5 sets of switch panel modules 1 are independent of each other in setting, but are regarded as a whole in maintenance and troubleshooting, that is, the modules are used to form a "cloud circuit".

[0049] The fault setting switch panel module 1 allows users to select the corresponding node switch according to training needs, setting it to the open circuit or grounded position to simulate the corresponding fault near that node in the circuit. The simulated fault setting switch is shown in the attached diagram. Figure 4 As shown, attached Figure 4 The example shown is node 13, KG13.

[0050] The control method is as follows: If the 13th lamp position on the circuit is selected, the corresponding 13th switch on any module of AE can be turned off. For example, if KC13 is turned off in module C, the 13th node of the circuit will be simulated to be disconnected at lamp tube 6 in C and can be measured inside lamp tube C. However, the 13th node switch of other modules is prohibited from being turned off at this time.

[0051] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
