[0048] On the basis of the above embodiment:

[0049] As a preferred embodiment, it further comprises:

[0050] N sub-control devices 3 corresponding to the N air conditioner electrical cabinets 2, which are used to generate the corresponding test instruction according to the user instruction and send it to the air conditioner electrical cabinet 2.

[0051] In order to be able to individually and in detail control each air conditioner electrical cabinet 2, please refer to Figure 2 ,Figure 2 Another structure schematic diagram of the air conditioner electrical cabinet 2 fault personnel examination device provided by the present application is provided, N sub-control devices 3 are arranged, each sub-control device 3 corresponds to one air conditioner electrical cabinet 2, various switches and programs capable of controlling the corresponding air conditioner electrical cabinet 2 are arranged on the sub-control device 3, so that the staff can perform individual operation on a certain air conditioner electrical cabinet 2 on the sub-control device 3. Specifically, a plurality of fault setting switches are arranged on the sub-control device 3, different fault setting switches can generate different signals when pressed and send them to the controller in the sub-control device 3, the controller generates corresponding fault setting programs according to the signal content and sends them to the corresponding air conditioner electrical cabinet 2, and the air conditioner electrical cabinet 2 can also execute the corresponding simulation fault program after receiving the fault setting program. In addition, a temperature controller of the air conditioner electrical cabinet 2 is arranged on the sub-control device 3 to control whether the air conditioner electrical cabinet 2 is cooling or heating and the target temperature when cooling and heating, a time controller is arranged to control the examination time and the answering time, and an emergency stop switch is arranged to close the air conditioner electrical cabinet 2 in time to avoid accidents caused by the misoperation of the examinee, and the time controller and the emergency stop switch cooperate with each other to forcibly close the air conditioner electrical cabinet 2 after the examination time is over, so as to avoid the examinee delaying the examination time. Please refer to Figure 4 , Figure 4 A structure schematic diagram of a sub-control device 3 provided by the present application is provided, which is provided with an air conditioner electrical cabinet 2 power display lamp 301, a weak ventilation control switch 302, compressor control switches 303 and 306, ventilation fan control switches 304 and 305, a strong ventilation control switch 307, a time controller 308, a simulation fault setting module 309, an air conditioner electrical cabinet 2 cooling / heating temperature controller 310, an air conditioner electrical cabinet 2 emergency stop switch 311, preheating machine control switches 312 and 315, heater control switches 313 and 314, and various functions are realized by controlling the above switches. Based on this, by arranging N sub-control devices 3 corresponding to one air conditioner electrical cabinet 2, each air conditioner electrical cabinet 2 can be individually and in detail controlled.

[0052] As a preferred embodiment, the sub-control device 3 is also used to control the air conditioner electrical cabinet 2 to stop working when an actual fault of the air conditioner electrical cabinet 2 is detected.

[0053] In order to avoid accidents of the air conditioner electrical cabinet 2, in the application, considering that the levels of examinees are different, when the examinees with low level are taking the exam, the examinees may make some wrong operations, and the wrong operations may cause the air conditioner electrical cabinet 2 to have a real fault, for example, when the examinee connects some lines in the air conditioner electrical cabinet 2, it may cause the air conditioner electrical cabinet 2 to have a real short circuit fault, if the examinee does not realize this, it may cause the lines of the air conditioner electrical cabinet 2 to overheat and burn out, causing economic loss. Based on this, the sub-control device 3 will control the air conditioner electrical cabinet 2 to stop working when it detects that the corresponding air conditioner electrical cabinet 2 has an actual fault, specifically, a plurality of detection points can be set in the air conditioner electrical cabinet 2 in advance, and the sub-control device 3 detects the current and voltage of these monitoring points, and controls the air conditioner electrical cabinet 2 to stop working when the current and voltage are too large; the power input of the air conditioner electrical cabinet 2 can also be detected to judge whether there is a lack of power phase, and the air conditioner electrical cabinet 2 is controlled to stop working when it is missing; after the air conditioner electrical cabinet 2 is closed due to some reasons, in order to avoid damage to the air conditioner electrical cabinet 2 caused by continuous opening and closing, when the air conditioner electrical cabinet 2 is in the closed state, if the opening instruction is received, the sub-control device 3 will also judge whether the time from the last time the air conditioner electrical cabinet 2 is closed is greater than the preset time, and if it is greater, the air conditioner electrical cabinet 2 will be opened, otherwise it will wait until the time is greater than the preset time before opening; in addition, high and low voltage protection can also be set. Based on this, accidents of the air conditioner electrical cabinet 2 can be avoided.

[0054] As a preferred embodiment, the total control device 1 is also used to store N air conditioner electrical cabinets 2 corresponding examination instructions, and after receiving the power failure protection instruction, the N examination instructions are sent to the N air conditioner electrical cabinets 2 corresponding to the examination instructions.

[0055] In order to avoid repeated question setting, in the application, considering that a sudden power failure may occur during the exam, after the power is restarted, the total control device 1 needs to send the test questions, that is, the examination instructions to the air conditioner electrical cabinet 2 again, in order to avoid the total control device 1 sending new examination instructions to each air conditioner electrical cabinet 2 after the power is restarted, which may cause the test questions before and after to be inconsistent, when the total control device 1 sends the examination instructions to the air conditioner electrical cabinet 2, it will store these examination instructions and the correspondence between the examination instructions and the air conditioner electrical cabinet 2, if a sudden power failure occurs, after the power is restarted, a power failure protection instruction can be sent to the total control device 1, and after receiving the power failure protection instruction, the total control device 1 will not generate the examination instructions corresponding to each air conditioner electrical cabinet 2, but will take out the stored examination instructions and send them to the air conditioner electrical cabinet 2 corresponding to the examination instructions, in order to avoid repeated question setting.

[0056] As a preferred embodiment, the air conditioner electrical cabinet 2 comprises:

[0057] X condensers, Y compressors, Z electric heaters, load control circuits and communication modules, wherein X, Y and Z are positive integers;

[0058] The communication module is connected with the general control device 1 and the load control circuit respectively, and is used for sending the received examination instruction to the load control circuit and sending the received answer data to the general control device 1.

[0059] The load control circuit is connected with the X condensers, the Y compressors and the Z electric heaters respectively, and is used for controlling the condensers, the compressors and the electric heaters to execute corresponding simulation fault programs according to the examination instruction, and generating corresponding answer data according to the examinee operation instruction.

[0060] In order to simulate the air conditioning electrical cabinet 2 in the actual situation, in the present application, considering that the functions of the air conditioning electrical cabinet 2 actually applied on the train at least include ventilation, refrigeration and heating functions, based on this, the air conditioning electrical cabinet 2 in the present application also needs to realize these functions, so X condensers are arranged in each air conditioning electrical cabinet 2 for realizing the refrigeration function, Y compressors are arranged for realizing the ventilation function, and Z electric heaters are arranged for realizing the heating function, and the working conditions of these instruments are controlled and monitored through the load control circuit, specifically, a set of load control circuit corresponding to each condenser, compressor and electric heater is arranged, that is, a total of X+Y+Z load control circuits are arranged, and finally a communication module is arranged to communicate with the general control device 1. Based on this, by arranging multiple condensers, compressors, electric heaters, load control circuits and communication modules, etc., the air conditioning electrical cabinet 2 in the actual situation can be better simulated.

[0061] As a preferred embodiment, the corresponding answer data is generated according to the examinee operation instruction, including:

[0062] determining whether the examinee operation instruction is a correct operation instruction corresponding to the examination instruction;

[0063] if yes, generating answer data indicating that the answer is correct;

[0064] if no, generating answer data indicating that the answer is incorrect.

[0065] In order to accurately determine the test scores of the examinees, in the present application, the examinees need to perform operations on the air conditioner electrical cabinet 2 when taking the test, such as wiring on the air conditioner electrical cabinet 2, programming the core in the air conditioner electrical cabinet 2, or voltage detection on the line in the air conditioner electrical cabinet 2, etc. These operations are equivalent to the answers given by the examinees. Based on this, after the air conditioner electrical cabinet 2 receives the test instruction and executes the corresponding simulation fault program, the specific examinee operation instruction can be pre-set as the correct operation instruction of the test instruction, and all other examinee operation instructions are regarded as incorrect operation instructions. That is, the answers of the examinees are pre-set as the correct and incorrect answers of the test question. When the examinee operation instruction executed by the examinee is the pre-set correct operation instruction, it means that the examinee answers correctly, and the answer data indicating the correct answer is generated. Otherwise, the answer data indicating the incorrect answer is generated. Further, when there are multiple test instructions sent to the air conditioner electrical cabinet 2, different weights or scores can be pre-set for each test instruction. When the answer is correct, the corresponding score is increased, and different score proportions can be set according to the difficulty of different test instructions. It can be seen that by judging whether the examinee operation instruction is the correct operation instruction corresponding to the test instruction, the test scores of the examinees can be accurately determined.

[0066] As a preferred embodiment, when receiving multiple examinee operation instructions, the corresponding answer data is generated according to the examinee operation instructions, including:

[0067] Among all the examinee operation instructions, the number of examinee operation instructions existing in the pre-set operation instruction library is determined;

[0068] According to the number of instructions, the answer data indicating the number of incorrect operations is generated;

[0069] The total control device 1 is specifically used for generating N air conditioner electrical cabinet 2 corresponding test instructions, and determining the test scores of N air conditioner electrical cabinet 2 according to the number of incorrect operations in the answer data of N air conditioner electrical cabinet 2.

[0070] In order to accurately determine the test score of the examinee, in the application, the examinee needs to operate on the air conditioner electrical cabinet 2 during the test, such as wiring on the air conditioner electrical cabinet 2, programming the core in the air conditioner electrical cabinet 2, or voltage detection on the line in the air conditioner electrical cabinet 2, etc. However, due to the different skill levels of different examinees, the low-level examinees may make wrong operations during the test. These wrong operations are usually unrelated to the test instructions, because the low-level examinees cannot accurately determine the correct operation instructions, and need to exclude other factors through multiple operations to know the correct answer, that is, they cannot find the cause of the fault in time. The frequency of wrong operation of high-level examinees during the test is less. It can be seen that the number of wrong operations is related to the skill level of the examinee. Based on this, the examinee operation instructions unrelated to the test instructions of this time can be stored in the preset operation instruction library as the wrong operation instructions, and then the number of wrong operation instructions of the examinee during the test is recorded. After the answer is completed, the test score of the examinee can be determined based on the number of wrong operation instructions. Specifically, the fewer the number of wrong operations, the higher the test score, which can accurately determine the test score of the examinee.

[0071] As a preferred embodiment, it further comprises:

[0072] N display modules corresponding to the N air conditioner electrical cabinets 2 are connected, which are used to acquire and display the working parameters of the air conditioner electrical cabinet 2 corresponding to the display module itself. The working parameters include one or more of the strong ventilation load rate, the weak ventilation load rate, the load rate of each condensing fan, the load rate of each compressor, and the load rate of each electric heater.

[0073] In order to enable the staff and the examinee to simply know the current state of the air conditioner electrical cabinet 2, in the application, each air conditioner electrical cabinet 2 is connected with a display module. The display module can be an independent display module, or can be arranged in the sub-control device 3. A plurality of display units are arranged in the display module, which can respectively display the working state and load of each condensing fan in the air conditioner electrical cabinet 2, the working state and load of each compressor, the working state and load of each electric heater, the power supply phase, voltage and current, and other working parameters. In addition, the real time and the remaining test time can also be displayed to remind the examinee of the test situation. It can be seen that by arranging the display module, the staff and the examinee can simply know the current state of the air conditioner electrical cabinet 2.

[0074] As a preferred embodiment, the total control device 1 is specifically used for:

[0075] generating test instructions corresponding to the N air conditioner electrical cabinets 2, and starting to record the test time of each air conditioner electrical cabinet 2;

[0076] For any air-conditioning electrical cabinet 2, when receiving the answer data of the air-conditioning electrical cabinet 2, stop recording the examination time of the air-conditioning electrical cabinet 2;

[0077] For any air-conditioning electrical cabinet 2, determine the examination score corresponding to the air-conditioning electrical cabinet 2 according to the answer data and the examination time of the air-conditioning electrical cabinet 2.

[0078] In order to accurately determine the examination score of the examinee, in the present application, considering that the total examination time of the examinee will be different according to the skill level of the examinee when taking the examination, the examinee with higher skill level can usually complete the examination faster than the examinee with lower skill level, so the examination time at each air-conditioning electrical cabinet 2 can be recorded when the examination instruction is sent to each air-conditioning electrical cabinet 2, that is, when the test questions are issued, and the examination time of the air-conditioning electrical cabinet 2 can be stopped recording after the air-conditioning electrical cabinet 2 sends the answer data to the general control device 1, that is, after the examinee submits the examination paper, so as to obtain the actual examination time of each air-conditioning electrical cabinet 2, and finally determine the corresponding examination score based on the actual examination time, for example, if the answer data of all examinees is the correct answer, the shorter the actual examination time of the air-conditioning electrical cabinet 2, the higher the examination score of the examinee. Based on this, the examination score of the examinee can be accurately determined.

[0079] As a preferred embodiment, the general control device 1 is specifically further used for judging whether there is an examination time greater than a preset time in the examination times corresponding to the N air-conditioning electrical cabinets 2;

[0080] If yes, control the air-conditioning electrical cabinet 2 with the examination time greater than the preset time to stop working.

[0081] In order to avoid the examinee delaying the answer time, in the present application, considering that in the actual working condition, the staff needs to be able to timely handle the real faults of the air-conditioning electrical cabinet 2, so the answer time of the examinee can also reflect the skill level of the examinee, if the examinee cannot complete the examination within the specified time, it means that he may also not be able to timely handle the real faults of the air-conditioning electrical cabinet 2 in the actual working condition, based on this, a preset time is set as the longest examination time of this examination, that is, the examination deadline, the examination time of the examinee will be recorded at the same time when the examinee starts the examination, and it will be continuously judged whether the examination time is greater than the preset time, in the case that the answer of the examinee is successful, the examination time of the air-conditioning electrical cabinet 2 will be stopped recording after the air-conditioning electrical cabinet 2 sends the answer data to the general control device 1, usually the examination time is less than the preset time, but when it is detected that the examination time of a certain air-conditioning electrical cabinet 2 is greater than the preset time, it means that the examinee of the air-conditioning electrical cabinet 2 has not been able to send the answer data to the general control device 1 after the examination starts for a period of time, that is, the examinee has not been able to submit the examination paper within the specified time, at this time, the air-conditioning electrical cabinet 2 can be forced to stop working, thereby avoiding the examinee delaying the answer time.
