Description

Technical Field

[0001] The invention relates to the technical field of subway electric passenger cars, and in particular to a subway electric passenger car air conditioning training system and method based on online fault setting. Background Art

[0002] Subway electric passenger cars have the advantages of high speed and large capacity, which play a positive role in improving transportation capacity and travel efficiency. As an important part of subway vehicles, subway electric passenger car air conditioners ensure the air quality and body temperature in the car, which directly affects the passengers' riding experience and comfort. Once a failure occurs, it will greatly reduce the riding experience and comfort. Therefore, it is very important to adopt efficient training methods in subway electric passenger car training, cultivate a group of high-quality subway electric passenger car operation and maintenance personnel, and improve the maintenance efficiency and maintenance quality of electric passenger car air conditioners.

[0003] The first type of electric passenger car air conditioning system training adopts traditional theoretical training. The instructor explains the relevant theories while demonstrating the actual objects, and the trainees carry out practical operations and consolidate their knowledge. In this way, the trainees can deepen their understanding of the structure and refrigeration principles of the unit and simple fault analysis capabilities through the disassembly and assembly of the unit. However, the understanding and maintenance of faults remain at the theoretical and self-disassembly level. When faced with abnormalities, it is difficult to accurately judge the comprehensive fault type, efficiently lock the fault point, and promptly judge whether the fault can be solved. In addition, the actual teaching is time-consuming and laborious, and it is difficult to track and record and evaluate each trainee.

[0031] The present embodiment is described in detail below, and examples of the embodiment are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The subway electric passenger car air conditioning training system and method based on online fault setting of this embodiment are described below with reference to the accompanying drawings.

[0033] Figure 1 FIG. 1 is a structural block diagram of a subway electric passenger car air conditioning training system based on online fault setting according to an embodiment of the present invention. Figure 1 As shown, the subway electric passenger car air conditioning training system based on online fault setting includes a fault setting module and an air conditioning physical platform connected thereto. The fault setting module is used to receive a fault injection instruction, and send a physical fault signal and a software simulated fault signal based on a predetermined fault type in the fault injection instruction; the air conditioning physical platform includes a control console, which is used to receive a physical fault signal and a software simulated fault signal, and control the execution of a physical fault action and a software simulated fault action, so as to realize the subway electric passenger car air conditioning hardware fault and software fault training.

[0034] In this embodiment, the predetermined fault types include at least refrigeration and ventilation faults, pressure faults, and mechanical equipment overcurrent faults. After receiving the fault injection instruction, the fault setting module can inject a physical fault signal into the air conditioning physical platform according to the predetermined fault type in the fault injection instruction. The physical fault signal includes multiple fault elements, and the multiple fault elements include at least hardware fault types, hardware fault parameters, and hardware environmental interference factors. When the control console in the air conditioning physical platform receives the physical fault signal, it controls the fault setting switches at the relays, control power supplies, pressure switches, ventilation units, and other components therein to operate, thereby generating a corresponding physical fault, wherein the physical fault signal at least specifically includes a cooling fan path fault signal, a power supply path fault signal, a compressor fault signal, and a low-pressure fault signal caused by the action of the pressure switch.

[0035] The console in the physical air-conditioning platform can also receive software simulated fault signals sent from the fault setting module, and cause the physical air-conditioning platform to generate corresponding faults by simulating low-voltage fault signals caused by misalignment of the temperature sensor, simulating low-voltage fault signals caused by short circuit of the return air outlet, simulating high-voltage fault signals caused by misalignment of the pressure sensor, and simulating overcurrent fault signals caused by fault of the main power supply relay, etc. In this embodiment, the physical faults and the software simulated faults form a good complementary effect, which can enhance the training effect.

[0036] In one embodiment of the present invention, the air conditioning physical platform also includes multiple physical hardware, which at least includes an air conditioning control cabinet (including a control panel), an air conditioning unit, a passenger compartment air duct model, and a special maintenance tool cabinet. During training, the air conditioning unit and the passenger compartment air duct model can be used by trainees to perform actual operations of disassembling and replacing air conditioning parts. In this embodiment, the air conditioning physical platform uses the actual air conditioning system of a subway train. The structural diagram of the air conditioning physical platform is shown in the figure below. Figure 2 shown.

[0037] In one embodiment of the present invention, the subway electric passenger car air conditioning training system based on online fault setting also includes an air conditioning training management system, which includes a teacher end and a student end, the teacher end is used for teacher identity login, and the student end is used for student identity login; the air conditioning training management system also includes a theoretical teaching module and a practical training assessment module, the theoretical teaching module is used to facilitate the release of theoretical teaching content on the teacher end, and to facilitate the training and learning of theoretical teaching content on the student end; the practical training assessment module is used to facilitate the release of practical training assessment content on the teacher end, and to facilitate practical training assessment on the student end. The air conditioning training management system also includes a fault simulation injection module, which is used to call the fault setting data and send the fault injection instruction.

[0038] Specifically, the air conditioning training management system includes an instructor side and a trainee side, namely an instructor platform and a trainee platform. Instructors and trainees each register and use an account password to choose different identities to log in to their respective platforms. The air conditioning training management system is divided into a theoretical teaching module, a fault simulation injection module, and a practical training assessment module. Instructors can log in to the theoretical teaching module in the air conditioning training management system, publish theoretical teaching content to trainees by calling theoretical teaching materials in the database, and explain and demonstrate the principles of the air conditioning system. At the same time, instructors can publish practical training assessment content on the practical training assessment module, so that trainees can log in for theoretical learning, practical training platform fault repair training, and participate in theoretical and practical training assessments. In this embodiment, the fault simulation injection module integrates prefabricated fault setting programs for each fault point. When in use, the instructor can log in to the fault simulation injection module, call the fault setting data, and send fault injection instructions to realize the hardware and software simulation of air conditioning system faults. The structural diagram of the air conditioning training management system is shown in the figure. Figure 3 shown.

[0039] In this embodiment, the air conditioning training management system can be expected to achieve the following functions: air conditioning system component equipment recognition training; air conditioning system control circuit recognition training; air conditioning system comprehensive fault maintenance training.

[0040] The following is an example of using physical fault signals and software simulated fault signals to implement air conditioning system hardware and software fault training.

[0041] The fault setting module can inject physical fault signals. The fault setting module issues fault injection instructions to the hardware control unit of the physical air-conditioning platform. For the injection of physical fault signals, this process can be expressed by the following formula: Fault injection instruction = specific hardware fault type × fault parameter + hardware environment interference factor. After receiving the fault injection instruction, the console simulates the occurrence of faults by controlling the temperature sensor, pressure sensor, controller, contactor, pressure contact switch, temperature sensing switch and other actions in the physical air-conditioning platform.

[0042] Taking the temperature sensor as an example, assume that the normal relationship between temperature and output voltage is T=k×V+b, where T is temperature, V is output voltage, and k and b are constants, such as k is sensitivity and b is offset. When a real fault signal is injected, this relationship may be disturbed by changing the resistance value inside the sensor, such as increasing the resistance value to reduce the output voltage at the same temperature, thereby simulating the temperature measurement inaccuracy caused by the temperature sensor failure.

[0043] For pressure sensors, under normal circumstances, there is a functional relationship between pressure and output current: P = f(I), where P represents pressure and I represents the output current of the pressure sensor. When a real fault signal is injected, a variable resistor can be connected to the signal transmission line of the pressure sensor to change the value of the pressure sensor output current I, thereby causing a deviation in pressure measurement and simulating a pressure sensor fault.

[0044] For controllers, their control logic usually consists of a series of conditional judgments and command outputs. When a physical fault signal is injected, the controller can output incorrect control commands by changing the input signal of the controller or directly modifying the program code inside the controller. For example, under normal circumstances, cooling is started when the temperature exceeds the threshold. By modifying the threshold or control logic through fault injection, the controller starts cooling when the temperature does not reach the threshold.

[0045] For the contactor, its opening and closing state is determined by the control signal. When the real fault signal is injected, the arrival time of the control signal can be delayed or advanced by connecting a capacitor or inductor to the control signal line, resulting in abnormal opening and closing of the contactor and simulating the contactor fault.

[0046] The injection of software simulated fault signals is achieved through a series of complex simulation algorithms. When simulating a low-voltage fault caused by a misaligned temperature sensor, the following algorithm can be used: First, set the normal temperature range [Tmin, Tmax] and the corresponding pressure range [Pmin, Pmax]. Tmin and Tmax are the lower and upper limits of the normal temperature range, and Pmin and Pmax are the lower and upper limits of the corresponding pressure range. During fault simulation, a temperature value Tfault that deviates from the normal range is randomly generated, and the corresponding error pressure value is calculated based on a preset error mapping function Pfault = g(Tfault), which is fed back to the system to simulate a low-voltage fault.

[0047] When simulating a low-pressure fault caused by a short circuit in the return air outlet, this can be achieved by modifying the system's duct resistance calculation function. Assume that under normal circumstances, the duct resistance R = h(A, V), where h is the duct resistance function, A is the area of ​​the fresh air outlet, and V is the wind speed. During fault simulation, the fresh air outlet area A is suddenly reduced to an abnormal value, resulting in an increase in the calculated duct resistance, thereby simulating a low-pressure fault caused by a short circuit in the return air outlet.

[0048] When simulating a high-pressure fault caused by a misaligned pressure sensor, similar to the simulation of a misaligned temperature sensor, a pressure value Pfault outside the normal range is randomly generated, and the corresponding error temperature value is calculated based on the error mapping function Tfault=f(Pfault) and fed back to the system.

[0049] When simulating an overcurrent fault caused by a main power relay failure, an abnormal current increment term Iextra = a×t can be added to the current detection algorithm, where a is the preset overcurrent growth coefficient and t is the time. When the detected current value plus Iextra exceeds the normal threshold, an overcurrent fault is simulated. The specific air conditioning system fault injection process is as follows: Figure 4 shown.

[0050] Figure 5 The overall structure diagram of the subway train air conditioning training system based on online fault settings is shown in Figure 2. Figure 5As shown, the instructor enters the air conditioning training management system through the instructor port and formulates a teaching plan through the theoretical teaching module. The trainees enter the air conditioning training management system through the trainee port to conduct training and learning according to the teaching plan. The instructor can also publish the practical training assessment content through the practical training assessment module to conduct practical training assessment on the trainees. When fault simulation is required, the instructor can send a fault injection instruction to the fault setting module through the fault simulation injection module. After receiving the fault injection instruction, the fault setting module sends a physical fault signal and a software simulation fault signal based on the predetermined fault type in the fault injection instruction. After receiving the physical fault signal and the software simulation fault signal, the console in the physical platform of the air conditioner controls the execution of the physical fault action and the software simulation fault action, thereby realizing the training of hardware fault and software fault of the air conditioner in the subway electric passenger car.

[0051] Furthermore, the present invention also provides a subway electric passenger car air conditioning training method based on online fault setting.

[0052] Figure 6 Flow chart of the subway electric car air conditioning training method based on online fault setting according to an embodiment of the present invention. Figure 6 As shown, the method includes:

[0053] Step S101: receiving a fault injection instruction, and sending a physical fault signal and a software simulated fault signal based on a predetermined fault type in the fault injection instruction.

[0054] Step S102: receiving a real fault signal and a software simulated fault signal, and controlling the execution of a real fault action and a software simulated fault action, so as to implement training on hardware fault and software fault of air conditioners in subway electric passenger cars.

[0055] The specific training method for subway electric passenger car air conditioning based on online fault setting is as follows:

[0056] In the air conditioning training management system, instructors and trainees log in to their respective platforms according to different accounts. The air conditioning training management system is divided into three modules, namely the theoretical teaching module, the practical training assessment module and the fault simulation injection module. The instructor can log in to the instructor side and call the corresponding teaching materials and fault setting data in the database through the air conditioning training management system, and realize the fault injection of the air conditioning physical platform through the fault setting data. Trainees can enter the instructor's classroom through the air conditioning training management system to learn the principles and structural cognition of the air conditioning system; at the same time, they can also enter the practical training assessment module for practice. The air conditioning training management system pre-stores theoretical learning content related to the air conditioning system, and based on typical faults in the actual operation of electric passenger cars, summarizes the three common types of air conditioning systems: refrigeration and ventilation faults, mechanical equipment overcurrent faults and pressure faults. Instructors can call materials through the air conditioning training management system to teach and train trainees, and at the same time, they can select the fault data that needs to be set through the air conditioning training management system, transmit it to the fault setting module, and inject faults into the air conditioning physical platform through the interface. See the attached structural diagram of the air conditioning training management system. Figure 3 .

[0057] In the fault setting module, there is information interaction between the fault setting module, the air-conditioning training management system and the air-conditioning physical platform. After the fault setting module receives a specific fault injection instruction sent by the air-conditioning training management system, it can inject a physical fault signal or a software simulated fault signal according to a predetermined fault type. The fault setting module issues a fault injection instruction to the hardware control unit in the air-conditioning physical platform. After receiving the fault injection instruction, the air-conditioning physical platform simulates the occurrence of a fault by controlling the actions of the temperature sensor, pressure sensor, controller, contactor, pressure contact switch, temperature sensing switch, etc. in the air-conditioning physical platform; at the same time, it can simulate software simulated fault signals to realize the simulation of software faults, thereby protecting the air-conditioning physical platform while ensuring the personal safety of trainees during fault training.

[0058] Among them, the physical faults injected by the fault setting module and the injection method are as follows:

[0059] Control the fault of the cooling fan circuit to set the switch action to realize the cooling fan fault injection; control the fault of the power supply circuit to set the switch action to realize the power supply damage fault injection; control the compressor contactor switch action to realize the compressor fault injection and control the pressure switch action to realize the low voltage fault injection.

[0060] The software faults and injection methods that can be simulated through the fault setting module are as follows: simulate low-voltage faults caused by temperature sensor misalignment; simulate low-voltage faults caused by short circuit of return air outlet; simulate high-voltage faults caused by pressure sensor misalignment; simulate overcurrent faults caused by main power relay failure. For specific air conditioning system fault injection process, please see the attached Figure 4 .

[0061] The air-conditioning physical platform uses the actual subway air-conditioning system, which is mainly composed of the following parts: air-conditioning units, passenger compartment air duct models, air-conditioning control cabinets (including control panels) and special maintenance tool cabinets. During training, the air-conditioning units and passenger compartment air duct models can be used by trainees to perform actual operations of disassembling, assembling and replacing air-conditioning parts. The fault setting module can inject physical fault signals into the air-conditioning physical platform. When the air-conditioning physical platform receives the physical fault signal, it controls the fault setting switches of the relays, control power supplies, pressure switches, ventilation units and other components to operate and generate faults. The air-conditioning physical platform can also receive software simulated fault signals to realize software fault simulation. The physical faults and software simulated faults form a good complementary effect, which can enhance the training effect. The air-conditioning physical platform is attached. Figure 2 .

[0062] In summary, the fault setting module used in the present invention can simulate the fault of the air-conditioning system through the physical fault signal and the software simulation fault signal, and achieve the purpose of all-round teaching through simulation. The physical air-conditioning platform used in the present invention is a physical platform of the subway electric passenger car. The physical air-conditioning platform and the fault setting module can exchange information, and can realize the real presentation of hardware faults and software faults on the physical air-conditioning platform, thus improving the fault training project. The air-conditioning training management system used in the present invention distinguishes between the instructor and the trainee platform. The instructor can formulate different theoretical teaching or practical training assessment tasks according to actual teaching needs, and the trainees can also independently choose the learning content according to their own learning situation, and the flexibility of the entire teaching process is greatly improved. At the same time, from the overall point of view, the present invention has low operating difficulty, low economic cost, and simpler subsequent maintenance.
