The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a schematic structural view of a ground function testing system of an aircraft windshield warming controller according to an embodiment of the present invention, and as shown in fig. 1, the system includes: the system comprises a windshield warming controller 5, a fault control module 11, a fault signal simulation module 3 and a fault detection module 2.
Illustratively, the fault control module 11 is used for sending a control instruction for simulating a fault signal to the fault signal simulation module 3, after the fault signal simulation module 3 receives the control instruction for simulating the fault signal, the fault signal simulation module executes an operation corresponding to the control instruction according to the control instruction to generate a simulated fault signal of the windshield heating controller 5, the fault detection module 2 detects a fault state output after the windshield heating controller 5 executes the simulated fault signal, mutual verification is performed according to the fault state of the windshield heating controller 5 detected by the fault detection module 2 and the input simulated fault signal, and whether the fault state of the windshield heating controller 5 detected by the fault detection module 2 is consistent with the input simulated fault signal or not is observed.
Optionally, the fault control module 11 is connected to the fault signal simulation module 3, and configured to send a control instruction to the fault signal simulation module 3.
For example, the control instruction may be generated by the fault control module 11, or the fault control module 11 may directly invoke a control instruction of an externally input simulated fault signal, and the fault control module 11 sends the control instruction of the simulated fault signal to the fault signal simulation module 3, so as to control the fault signal simulation module 3 to simulate the simulated fault signal of the windshield heating controller 5. Optionally, the analog fault signal may be a power failure signal, a relay fault signal, a heater fault signal, a temperature sensor fault signal, a temperature overheating fault signal, or the like, and the control command may be a string of software codes, or may be a piece of audio data, or the like. For example, taking the example that the analog fault signal is a power supply fault signal, the ac power supply signal of each warming channel of the windshield warming controller 5 is tested, and when the three-phase ac a phase of the power supply that supplies the dc power to the warming channel 1 of the windshield warming controller 1 needs to be disconnected during the test, the control command may be a code of "power key for disconnecting the three-phase ac a phase of the power supply that controls the warming channel 1", or audio data, or the like. For another example, taking the example that the analog fault signal is a relay fault signal, the relay of windshield heating controller 5 is tested, and when the test is performed, the current flowing through windshield heating controller 5 is 1A, but the current for relay protection of the relay is 5mA, the control command may be a code or audio data of "providing the current of 1A for windshield heating controller 5". Other control commands such as warmer fault signals, temperature sensor fault signals, and over-temperature fault signals may be similar to the power supply fault signal and relay fault signal.
Optionally, the fault control module 11 obtains the simulated fault signal generation instruction, determines at least one control instruction corresponding to the simulated fault signal generation instruction, and sequentially sends the at least one control instruction to the corresponding components in the fault signal simulation module 3.
Illustratively, the fault control module 11 obtains a generation instruction of an externally input simulated fault signal, and according to the generation instruction of the simulated fault signal, the fault control module 11 may generate or directly call a control instruction of the externally input simulated fault signal corresponding to the generation instruction of the simulated fault signal, and sequentially send at least one control instruction to a corresponding component in the fault signal simulation module 3. The generation instruction of the analog fault signal may correspond to at least one control instruction, and for example, the control instruction corresponding to the generation instruction of the power fault signal may be: the heating channel 1 comprises an A-phase turn-off command and an A-phase turn-on command, a B-phase turn-off command and an A-phase turn-on command, a C-phase turn-off command and an C-phase turn-on command in three-phase alternating current, and the heating channel 2 comprises an A-phase turn-off command and an A-phase turn-on command, a B-phase turn-off command and an A-phase turn-on command, and a C-phase turn-off command and an A.
Alternatively, the components included in the fault signal simulation module 3 may be a power supply, a relay, a heater, a temperature sensor, a conductive film heating element, and the like, for example, taking the example that the simulated fault signal is a power fault signal, an ac power supply signal of each heating channel of the windshield heating controller 5 is tested, the fault control module 11 acquires a generation instruction for generating the power fault signal input from outside, and generates a control instruction corresponding to the power fault signal generation instruction according to the generation instruction, since the simulation of the power fault signal is simulated by controlling the opening and closing of a power key in a power supply module, and the power supply module supplies three-phase ac power to the windshield heating controller 5, the control instruction generated here may be any phase current of the three-phase ac power that is opened to any one of the heating channels of the windshield heating controller 5, for example, the power key may be a power key for turning off the phase a of the three-phase alternating current for controlling the power supply of the warming channel 1, and the power module turns off the power key corresponding to a of the three-phase alternating current for controlling the warming channel 1 in accordance with the control command. For another example, taking the example that the simulated fault signal is a relay fault signal, the fault control module 11 obtains an externally input generation command for generating the relay fault signal, and generates a control command corresponding to the relay fault signal generation command according to the generation command, for example, the control command is a current of 1A supplied to the windshield heating controller 5, and sends the control command to the relay in the fault signal simulation module 3, and since the current exceeds the relay protection current of the relay, the normally open contact of the relay is burned out.
In the technical solution of the above embodiment, the advantage of providing the fault control module 11 is that the fault control module is used to obtain a simulated fault signal generation instruction, generate or directly call at least one control instruction corresponding to the simulated fault signal generation instruction according to the simulated fault signal generation instruction, and sequentially send the at least one control instruction to corresponding components in the fault signal simulation module 3, and control the corresponding components in the fault signal simulation module 3 to execute the simulated fault signal, instead of manually operating to control generation and transmission of the simulated fault signal, so that manpower is saved, and when other subsequent related personnel need to perform the operation, the module can be directly used to perform the corresponding operation, time is saved, and work efficiency is improved.
Optionally, the fault signal simulation module 3 is connected to the windshield heating controller 5 by a cable, and is configured to receive the control instruction, execute the control instruction, and generate a simulated fault signal of the windshield heating controller 5.
For example, the fault signal simulation module 3 may be connected to the windshield heating controller 5 through a cable via an interface of the windshield heating controller 5, and referring to fig. 2, fig. 2 is a schematic structural diagram of a ground function test system of an aircraft windshield heating controller according to an embodiment of the present invention, for example, the fault signal simulation module 3 may be connected to the windshield heating controller 5 through a cable via an interface 51 of the windshield heating controller 5, and after receiving a control instruction of a simulated fault signal sent by the fault control module 11, the fault signal simulation module 3 implements a simulated fault signal corresponding to the control instruction on the windshield heating controller 5 according to the control instruction, so that the heated windshield controller 5 operates under the simulated fault signal. For example, taking the example that the simulated fault signal is a power failure signal, the ac power signals of the respective warming channels of the windshield warming controller 5 are tested, and after the fault signal simulation module 3 receives a control instruction sent by the fault control module 11 to turn off a power key for controlling the phase a of the three-phase ac power of the power supply of the warming channel 1, and according to the control instruction, the power supply module of the fault signal simulation module 3 turns off the power key corresponding to phase a of the three-phase ac power of the warming channel 1, a power failure signal is generated at this time, and the power failure signal is transmitted to the windshield warming controller 5 to be implemented, and then the windshield warming controller 5 at this time operates under the power key corresponding to the phase a of the three-phase ac power of the warming channel 1. For another example, taking the example that the simulated fault signal is a relay fault signal, when the relay in the windshield heating controller 5 is tested, after the fault signal simulation module 3 receives a control command that the windshield heating controller 5 provides a current of 1A sent by the fault control module 11, the windshield heating controller 5 is provided with a current of 1A according to the control command, a relay fault signal is generated at this time, and the relay fault signal is transmitted to the windshield heating controller 5 for implementation, so that the windshield heating controller 5 at this time operates at a current amount of 1A.
In the technical scheme of the above embodiment, the fault signal simulation module 3 is used to receive the control instruction of the simulated fault signal sent by the fault control module 11, and according to the control instruction, the simulated fault signal corresponding to the control instruction is implemented on the windshield heating controller 5, so that the windshield heating controller 5 works under the simulated fault signal, rather than artificially controlling the corresponding component corresponding to the simulated fault signal, thereby realizing the automation of the system and saving manpower.
Optionally, the fault detection module 2 is connected to the windshield warming controller 5 by a cable, and is configured to detect a fault state of the windshield warming controller 5, where the fault state includes: faulty and non-faulty.
For example, the fault detection module 2 can be cabled to the windshield warming controller 5 through another interface of the windshield warming controller 5, referring to figure 2, FIG. 2 is a schematic structural diagram of a ground function testing system of an aircraft windshield heating controller according to an embodiment of the invention, for example, the fault detection module 2 can be cabled to the windshield warming controller 5 through another interface 52 of the windshield warming controller 5, when the windshield heating controller 5 operates under the simulated fault signal implemented by the fault signal simulation module 3 to the windshield heating controller 5, the fault detection module 2 detects the fault state of the windshield heating controller 5, and mutually verifying the fault state of the windshield heating controller 5 detected by the fault detection module 2 and the input simulated fault signal, and judging whether the fault state of the windshield heating controller 5 detected by the fault detection module 2 is consistent with the input simulated fault signal.
For example, taking the example that the simulated fault signal is a power supply fault signal, the AC power supply signal of each heating channel of the windshield heating controller 5 is tested, taking the control instruction as the power key for disconnecting the three-phase alternating current phase a of the power supply of the controlled warming channel 1 as an example, the windshield warming controller 5 operates under the power key for disconnecting the three-phase alternating current phase a of the power supply of the controlled warming channel 1, if the fault detection module 2 detects that the windshield warming controller 5 has a fault, it means that the fault state of the windshield heating controller 5 detected by the fault detection module 2 is consistent with the input simulated fault signal, if the fault detection module 2 detects that the windshield heating controller 5 has no fault, it means that the fault state of the windshield heating controller 5 detected by the fault detection module 2 is inconsistent with the input simulated fault signal, and at this time, maintenance personnel are required to maintain the power key of the warming channel 1 of the windshield warming controller 5.
Optionally, the fault detection module 2 is further configured to detect whether the windshield warming controller 5 outputs a fault signal when the fault signal simulation module 3 provides any simulated fault signal; when the fault signal simulation module 3 switches the simulated fault signal to the normal signal, whether the fault signal output by the windshield heating controller 5 disappears is detected.
For example, when windshield warming controller 5 operates under any of the simulated fault signals applied to windshield warming controller 5 by fault signal simulation module 3, fault detection module 2 detects whether the state of windshield warming controller 5 is faulty or not, and when fault signal simulation module 3 switches the simulated fault signal to the normal signal, detects whether the state of windshield warming controller 5 is non-faulty or not. For example, taking the example that the analog fault signal is a power failure signal, the ac power signals of the heating channels of the windshield heating controller 5 are tested, the fault signal simulation module 3 provides the power failure signal for the windshield heating controller 5, specifically, the power supply assembly disconnects the power key corresponding to a in the three-phase ac power of the heating channel 1, the fault detection module 2 detects that the windshield heating controller 5 is faulty, and when the fault signal simulation module 3 closes the power key corresponding to the three-phase ac power a controlling the heating channel 1, the fault detection module 2 detects that the windshield heating controller 5 is not faulty, which indicates that the windshield heating controller 5 is intact and can be used normally. If the power supply component of the fault signal simulation module 3 disconnects the power key corresponding to the a in the three-phase alternating current of the warming channel 1, the fault detection module 2 does not detect that the windshield warming controller 5 has a fault, or when the fault signal simulation module 3 closes the power key corresponding to the three-phase alternating current a controlling the warming channel 1, the fault detection module 2 does not detect that the windshield warming controller 5 has no fault, which indicates that the windshield warming controller 5 has a problem and cannot be normally used, and a maintenance person needs to be contacted to maintain the power key of the warming channel 1 of the windshield warming controller 5.
In the technical solution of the above embodiment, the provision of the failure detection module 2 has the advantages that the failure detection module 2 is used to detect the failure state output after the windshield warming controller executes the simulated failure signal, mutual verification is carried out according to the fault state of the windshield heating controller detected by the fault detection module 2 and the input simulation fault signal, whether the fault state of the windshield heating controller detected by the fault detection module is consistent with the input simulation fault signal or not is observed, and when the windshield warming controller 5 operates under any of the simulated fault signals applied to the windshield warming controller 5 by the fault signal simulation module 3, the fault detection module 2 detects whether the state of the windshield warming controller 5 is faulty, when the fault signal simulation module 3 switches the simulated fault signal to the normal signal, it detects whether the state of the windshield heating controller 5 is fault-free. The effect of effectively verifying the response of the windshield warming controller to various fault signals is achieved.
According to the technical scheme of the embodiment of the invention, the fault control module is used for sending the control instruction for simulating the fault signal to the fault signal simulation module, and the fault control module is used for sending the control instruction for simulating the fault signal to the fault signal simulation module instead of manually controlling the transmission of the simulated fault signal, so that the labor is saved, and the working efficiency is improved. After the fault signal simulation module receives a control instruction for simulating a fault signal, the operation corresponding to the control instruction is executed according to the control instruction to generate a simulated fault signal of the windshield heating controller, and the operation corresponding to the control instruction is executed by using the fault signal simulation module without manually executing the corresponding operation, so that the automation of the system is realized, the working efficiency is improved, and the effect of efficiently simulating the fault signal of the windshield heating controller is realized. The fault detection module detects the fault state of output after windshield controller that heats execution simulation fault signal, and wherein, the fault state includes: and when the fault occurs or no fault occurs, mutual verification is carried out according to the fault state of the windshield heating controller detected by the fault detection module and the input simulation fault signal, and whether the fault state of the windshield heating controller detected by the fault detection module is consistent with the input simulation fault signal or not is observed. The effect of effectively verifying the response of the windshield warming controller to various fault signals is achieved.

For example, taking the example that the analog fault signal is a power supply fault signal, when the power supply component of the fault signal analog module 3 disconnects the corresponding power supply key a in the three-phase alternating current of the warming channel 1, the fault detection module 2 detects that the windshield warming controller 5 is in fault and sends the fault state to the unit warning system 62, and the unit warning system 62 receives the fault state sent by the fault detection module 2 and displays the fault state, where the display content may be that the windshield warming controller 5 is in fault. When the fault signal simulation module 3 controls the power key corresponding to the three-phase alternating current a of the warming channel 1 of the windshield warming controller 5 to be closed, the fault detection module 2 detects that the windshield warming controller 5 is not in fault, and sends the fault state to the unit warning system 62 for displaying, wherein the display content may be that the windshield warming controller 5 is not in fault.
