Technical Field

[0001] The present invention relates to the technical field of rail vehicle air-conditioning equipment, and in particular to a remote control system for a rail vehicle air-conditioning system. Background Art

[0002] Rail transit air conditioning systems generally have either local manual control or vehicle network automatic control. Both types of control require specific human intervention to execute. Since the onboard air conditioning systems are evenly distributed throughout the train, when an emergency occurs, onboard staff cannot reach the problem car in time and cannot control the air conditioning system in time. Summary of the Invention

[0003] In view of the above problems, the present invention proposes a remote control system for a rail transit vehicle air conditioning system.

[0004] The technical means adopted in the present invention are as follows:

[0006] The data acquisition module is provided on the air conditioning unit in each carriage and is used to collect data information of the air conditioning unit in each carriage;

[0007] The air conditioning system controller is connected to a data acquisition module on an air conditioning unit in a corresponding compartment, and is configured to obtain data information collected by the data acquisition module and transmit the data information and a control signal of the air conditioning system controller to a wireless router module; receive fault processing information transmitted by the wireless router module, and control the corresponding air conditioning unit according to the fault processing information;

[0008] The wireless router module is connected to the air conditioning system controller of each carriage, and is used to obtain the data information of the air conditioning units of the entire train carriage and the control signals of the air conditioning system controller and wirelessly transmit them to the remote mobile control terminal; and is used to obtain the fault handling information sent by the remote mobile control terminal and send it to the air conditioning system controller;

[0009] The remote mobile control terminal is used to obtain the data information of the air-conditioning units of the entire train carriage and the control signals of the air-conditioning system controller, and process the data information and the control signals to generate fault handling information, and wirelessly send the fault handling information to the wireless router module.

[0010] Furthermore, the data acquisition module includes a temperature sensor, a current sensor and a pressure difference controller;

[0011] The control signals of the air conditioning system controller are control instructions and contactor feedback signals.

[0012] Furthermore, the remote mobile control terminal includes a communication module, a processor and a storage module;

[0013] The communication module is used to perform wireless data transmission with the wireless router module;

[0014] The processor and storage module are used to predict system component failures based on the system component failure prediction strategy based on the temperature signal collected by the temperature sensor;

[0015] Used to obtain contactor feedback signals to obtain the working status of system components, obtain the actual operating conditions of the system based on the working status of system components, and compare the actual operating conditions of the system with the calculated conditions of the system to obtain the working status of the system;

[0016] Used to obtain contactor feedback signals to obtain the working status of system components, and predict the life of system components based on the working status of system components;

[0017] And based on the system component failure prediction, system working status and system component life prediction results, it generates component replacement reminders, customer selective processing, system normal, system abnormality and corresponding fault handling information during customer maintenance.

[0018] Furthermore, the system component failure prediction strategy is as follows: Based on each sensor reading Di and the sum of n sensor values ​​D 总 The average value of the sensor fault prediction is used to judge Di<D 总 / n±0.5, if not, it is determined that the temperature sensor system component of the air conditioning unit is faulty, and the fault handling information is a component replacement reminder, where i=1, 2…n, D 总 =D1+D2…Dn.

[0019] Furthermore, the working states of the system components including the working state of the ventilator, the working state of the condensing fan, the working state of the compressor and the working state of the electric heater are obtained according to the feedback signal of the contactor;

[0020] The actual operating conditions of the system are obtained according to the working status of the system components as follows:

[0021] When the fan is in working state, the actual operating condition of the system is ventilation condition;

[0022] When the ventilator, condensing fan and compressor are all in working state, the actual operating condition of the system is cooling condition;

[0023] When the electric heater and ventilator are in working state, the actual operating condition of the system is heating condition;

[0024] When the ventilator, condensing fan, compressor and electric heater are not working, the actual operating condition of the system is the shutdown condition.

[0025] Furthermore, the specific process of comparing the actual system operating conditions with the system calculated conditions to obtain the system working status is as follows:

[0026] Determine whether the actual operating conditions of the system match the calculated operating conditions of the system. If not, the fault handling information is that the system is abnormal. If so, compare the current value collected by the current sensor with the actual current value of the corresponding operating condition to determine whether the current value collected by the current sensor matches the actual current value of the corresponding operating condition. If not, determine that the fault handling information is that the system is abnormal. If so, determine that the fault handling information is that the system is normal.

[0027] Furthermore, the processor and storage module are further configured to perform a secondary fault judgment on the system when it is determined that the actual operating condition of the system matches the calculated operating condition of the system. The specific process is as follows;

[0028] When the actual working condition of the system is ventilation condition, the pressure difference controller value is obtained. If the pressure difference controller value is less than the first pressure difference setting value, the secondary fault is determined to be poor ventilation;

[0029] When the actual operating condition of the system is cooling condition, the temperature value of the air supply temperature sensor of the air conditioning unit is obtained. If the temperature value of the air supply temperature sensor is greater than the first cooling air supply temperature setting value, the secondary fault is determined to be cooling failure.

[0030] When the actual operating condition of the system is heating, the temperature value of the air supply temperature sensor of the air conditioning unit is obtained. If the temperature value of the air supply temperature sensor is less than the first heating air supply temperature setting value, the secondary fault is determined to be heating failure.

[0031] If the secondary fault is determined to be poor ventilation, poor cooling or poor heating, the fault handling information is selectively handled by the customer; if there is no secondary fault, the fault handling information is that the system is normal.

[0032] Furthermore, the life prediction of system components includes the life prediction of ventilators, condensing fans, compressors, electric heaters and filters;

[0033] The air conditioning system controller is further used to send the operating time Ti of the system components, and the processor and storage module store the rated life threshold T1 and reminder threshold T2 of the system components;

[0034] The life prediction strategy for ventilators, condensing fans, compressors, and electric heaters is as follows: The life of system components is predicted based on the operating time Ti, rated life threshold T1, and reminder threshold T2 of the system components. If T1>Ti≥T2, the fault handling information is to remind the customer to repair the system. Otherwise, the fault handling information is that the system is normal.

[0035] The filter life prediction strategy is as follows: the filter life is predicted based on the pressure difference P1 inside and outside the filter and the rated pressure difference threshold P, and P1>P is judged. If so, the fault handling information is to remind the customer to repair it. If not, the fault handling information is that the system is normal.

[0036] Furthermore, the data acquisition module communicates with the air-conditioning system controller via an RS485 bus, the air-conditioning system controller communicates with the wireless router module via an Ethernet bus, and the wireless router module communicates with the remote mobile control terminal via 5G.

[0037] Compared with the prior art, the remote control system of the rail transit vehicle air-conditioning system disclosed in the present invention has the following beneficial effects: due to the remote mobile control terminal set up in the present invention, and the air-conditioning system controller can judge the working condition of the air-conditioning unit according to the data information collected by the data acquisition module and the control signal of the air-conditioning system controller, the remote mobile control terminal can obtain fault processing information based on the data information and control signal, and because the air-conditioning unit information in all cars is gathered together through the wireless transmission module, it is convenient for operators to promptly discover possible faults of any air-conditioning unit and handle the faults. At the same time, when the air-conditioning system is in an emergency, although the on-board staff cannot reach the car where the problematic air-conditioning unit is located in time to manually control it, it can be output to the air-conditioning system through the remote mobile control terminal, allowing the air-conditioning system to perform the corresponding working mode, thereby avoiding the problem of poor passenger experience caused by untimely operation.

[0042] like Figure 1 and Figure 2 The figure shows a remote control system for a rail transit vehicle air conditioning system disclosed in the present invention, comprising a data acquisition module 1, an air conditioning system controller 4, a wireless router module 10 and a remote mobile control terminal 5;

[0043] The data acquisition module 1 is provided on the air conditioning unit 2 in each carriage for collecting data information of the air conditioning unit 2 in each carriage. Generally, a train has 6 carriages, and each carriage is provided with two sets of air conditioning units 2;

[0044] Each carriage is equipped with an air-conditioning control cabinet 8, which houses an air-conditioning system controller 4. The air-conditioning control cabinet 8 is connected to 380Vac and 110Vdc power supplies. The air-conditioning control cabinet 8 needs to supply the air-conditioning unit with a main circuit 3-phase 380Vac power supply and a control circuit 110Vdc power supply. The main circuit power supply is connected to the air-conditioning control cabinet 8 and the air-conditioning unit 2 via a main circuit wiring harness connector for use by the main components of the air-conditioning unit. The control circuit power supply is connected to the air-conditioning control cabinet 8 and the air-conditioning unit 2 via a control circuit wiring harness connector for use by the air-conditioning unit control components. The air-conditioning system controller 4 in each air-conditioning control cabinet is connected to the data acquisition module on the air-conditioning unit in the corresponding carriage via a 485 communication line 3 to obtain data information collected by the data acquisition module 1. The data information and the control signal of the air-conditioning system controller are sent to the wireless router module 10. The fault handling information sent by the wireless router module 10 is received, and the corresponding air-conditioning unit 2 is controlled according to the fault handling information.

[0045] The wireless router module 10 is connected to the air-conditioning system controller of each carriage, that is, the air-conditioning system controllers in multiple carriages are connected to the same wireless router module 10, and is used to obtain the data information of the air-conditioning units of the entire train carriage and the control signals of the air-conditioning system controllers and wirelessly transmit them to the remote mobile control terminal 5; and is used to obtain the fault handling information sent by the remote mobile control terminal 5 and send it to the air-conditioning system controller 4. Preferably, the wireless router module transmits information in the form of 5G wireless transmission;

[0046] The remote mobile control terminal 5 is used to obtain the data information of the air-conditioning unit 2 of the entire train car and the control signal of the air-conditioning system controller 4, and process the data information and the control signal to generate fault handling information, and wirelessly send the fault handling information to the wireless router module 10.

[0047] Specifically, the data acquisition module includes a temperature sensor, a current sensor and a pressure difference controller;

[0048] The control signals of the air conditioning system controller are control instructions and contactor feedback signals.

[0049] like Figure 3 As shown, the remote mobile control terminal 5 includes a communication module, a processor and a storage module;

[0050] The communication module is used to perform wireless data transmission with the wireless router module;

[0051] The processor and storage module are used to predict system component failures based on the temperature signals collected by the temperature sensor according to the system component failure prediction strategy. Specifically, the system component failure prediction strategy is as follows: the processor and storage module are used to obtain the temperature data of multiple temperature sensors with the same function (such as air supply temperature sensors) on the air conditioning units in the entire train compartment, and calculate the value of each sensor Di and the sum of the n sensor values ​​D. 总 The average value of the sensor fault prediction is used to judge Di<D 总 / n±0.5, if not, it is determined that the temperature sensor system component of the air conditioning unit is faulty, and the fault handling information is a component replacement reminder, where i=1, 2…n, D 总 =D1+D2…Dn. Through the prediction of system component failure, control personnel or maintenance personnel can easily discover the failure in time and replace and repair components in time.

[0052] The processor and storage module are further configured to obtain contactor feedback signals to obtain the working states of system components, obtain the actual operating conditions of the system based on the working states of the system components, and compare the actual operating conditions of the system with the calculated working conditions of the system to obtain the working states of the system; specifically, the contactor feedback signals include ventilator contactor feedback signals, condensing fan contactor feedback signals, compressor contactor feedback signals, and electric heater contactor feedback signals, and the working states of the system components obtained based on the contactor feedback signals include the working states of the ventilator, the working states of the condensing fan, the working states of the compressor, and the working states of the electric heater;

[0053] The actual operating conditions of the system are obtained according to the working status of the system components as follows:

[0054] When the fan is in working state, the actual operating condition of the system is ventilation condition;

[0055] When the ventilator, condensing fan and compressor are all in working state, the actual operating condition of the system is cooling condition;

[0056] When the electric heater and ventilator are in working state, the actual operating condition of the system is heating condition;

[0057] When the ventilator, condensing fan, compressor and electric heater are not working, the actual operating condition of the system is the shutdown condition.

[0058] The specific process of comparing the actual system operating conditions with the system calculated conditions to obtain the system working status is as follows:

[0059] Determine whether the actual operating conditions of the system match the calculated operating conditions of the system. If not, the fault handling information is a system abnormality. If so, compare the current value collected by the current sensor with the actual current value of the corresponding operating condition to determine whether the current value collected by the current sensor matches the actual current value of the corresponding operating condition. If not, determine that the fault handling information is a system abnormality. If so, determine that the fault handling information is normal. The calculated operating conditions of the system can be directly sent by the air-conditioning system controller to the remote mobile control terminal, or can be obtained by the remote mobile control terminal based on the corresponding data. The specific calculation process is a conventional means in this field.

[0060] That is, based on whether the corresponding contactor is closed, it is judged whether the corresponding component is working, and then based on the working status of different components, the actual operating conditions of the current air-conditioning unit are judged. By comparing the actual operating conditions with the operating conditions calculated by the system, it can be judged whether the current system is working normally. Furthermore, in order to further ensure the accuracy of the judgment, the current value of the current sensor is compared with the current value of the corresponding working condition to improve the accuracy of the system working status judgment, thereby ensuring the reliability of the system.

[0061] Furthermore, the processor and storage module are further configured to perform a secondary fault judgment on the system when it is determined that the actual operating condition of the system matches the calculated operating condition of the system. The specific process is as follows;

[0062] When the actual working condition of the system is ventilation condition, the pressure difference controller value is obtained. If the pressure difference controller value is less than the first pressure difference setting value, the secondary fault is determined to be poor ventilation;

[0063] When the actual operating condition of the system is cooling condition, the temperature value of the air supply temperature sensor of the air conditioning unit is obtained. If the temperature value of the air supply temperature sensor is greater than the first cooling air supply temperature setting value, the secondary fault is determined to be cooling failure.

[0064] When the actual operating condition of the system is heating, the temperature value of the air supply temperature sensor of the air conditioning unit is obtained. If the temperature value of the air supply temperature sensor is less than the first heating air supply temperature setting value, the secondary fault is determined to be heating failure.

[0065] If the secondary fault is determined to be poor ventilation, poor cooling or poor heating, the fault handling information is selectively handled by the customer; if there is no secondary fault, the fault handling information is that the system is normal.

[0066] By judging the system's secondary faults, the reliability of the air-conditioning system is further guaranteed, avoiding the problem of poor passenger riding experience due to air-conditioning failures. At the same time, it can also promptly remind relevant operating or maintenance personnel to maintain the corresponding components.

[0067] The processor and storage module are further used to obtain contactor feedback signals to obtain the working status of system components, and to predict the life of system components according to the working status of system components;

[0068] Specifically, the system component life prediction includes the ventilator life prediction, condenser fan life prediction, compressor life prediction, electric heater life prediction and filter life prediction;

[0069] The air conditioning system controller is further used to send the operating time Ti of the system components, and the processor and storage module store the rated life threshold T1 and reminder threshold T2 of the system components;

[0070] The life prediction strategy for ventilators, condensing fans, compressors, and electric heaters is as follows: The life of system components is predicted based on the operating time Ti, rated life threshold T1, and reminder threshold T2 of the system components. If T1>Ti≥T2, the fault handling information is to remind the customer to repair the system. Otherwise, the fault handling information is that the system is normal.

[0071] The filter life prediction strategy is as follows: the filter life is predicted based on the pressure difference P1 inside and outside the filter and the rated pressure difference threshold P, and P1>P is judged. If so, the fault handling information is to remind the customer to repair it. If not, the fault handling information is that the system is normal.

[0072] Through the life prediction of system components, timely alarms can be issued for components that are about to reach the rated life threshold, and relevant operating or maintenance personnel can be reminded in time to maintain the corresponding components, thereby ensuring the normal operation of the air-conditioning system.

[0073] The processor and storage module are also used to generate corresponding fault handling information such as component replacement reminders, customer selective processing, system normality, system abnormality, and reminders for customer maintenance based on system component fault predictions, system operating status, and system component life prediction results, and send specific faults and fault handling information to the communication module, which is then sent to the wireless router module by the communication module, thereby facilitating the air-conditioning system controller to control the air-conditioning unit accordingly.

[0074] The present invention is provided with a remote mobile control terminal, and the air conditioning system controller can judge the working condition of the air conditioning unit according to the data information collected by the data acquisition module and the control signal of the air conditioning system controller, and obtain fault processing information based on the data information and control signal. Moreover, since the air conditioning unit information in all compartments is gathered together through the wireless transmission module, it is convenient for the operator to promptly discover any possible fault of the air conditioning unit and handle the fault. At the same time, when the air conditioning system is in an emergency, although the on-board staff cannot reach the compartment where the problematic air conditioning unit is located in time to manually control it, the remote mobile control terminal can be used to output to the air conditioning system, so that the air conditioning system can perform the corresponding working mode, thereby avoiding the problem of poor passenger experience caused by untimely operation. The present invention has high reliability, stable operation, simple structure, low cost, easy implementation, and low control delay.

[0075] For the control of the air-conditioning system, remote mobile terminal control has a higher priority than manual control, and manual control has a higher priority than vehicle network control.

[0076] Furthermore, the data acquisition module also includes high and low pressure switches, high and low pressure sensors, and voltage sensors; the remote mobile control terminal also has a display function for displaying all the content that needs to be displayed, such as various data information and various fault information collected by the data acquisition module.

[0077] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
