[0001] This application relates to the field of rail transit equipment technology, and more specifically, to a general system for bogie safety testing and a vehicle. Background Technology

[0002] Currently, bogie testing uses a standard 3U chassis and mainly includes three testing devices: axle temperature monitoring, instability detection, and stability detection.

[0003] However, due to differences in the acquisition interfaces, data acquisition volume, availability requirements, etc. of the three detection devices, the three devices adopted different bus architecture platforms, resulting in the complete incompatibility of the plug-ins of the three devices, including those with the same functions (such as power supply, storage, control, and communication).

[0004] Therefore, how to solve the above problems is an urgent issue that needs to be addressed. Summary of the Invention

Specifically, the use of the word "exemplary" is intended to present the concept in a concrete manner. In addition, in the embodiments of this application, the meaning expressed by "and / or" can be both, or it can be either one or the other.

[0050] The following will combine Figures 1 to 3 This application will specifically describe the general system for bogie safety inspection provided in its embodiments. For example, Figure 1 This is a schematic diagram of the functional modules of the general bogie safety testing system provided in the embodiments of this application.

[0051] like Figure 1 As shown, the bogie safety detection general system 100 includes: a main control board 110, a peripheral board 120, a backplane 130, a power supply board 140, a signal interface board 180, and a power distribution board 170.

[0052] The main control board 110 is connected to the peripheral board 120, the backplane 130, the power board 140, and the signal interface board 180, respectively.

[0053] The backplane 130 is provided with an RS485 bus 131, a first power line 133, a second power line 135 and an ETH switching bus 137.

[0054] The RS485 bus 131 is connected to the main control board 110, the peripheral board 120 and the signal interface board 180 respectively.

[0055] The main control board 110, the peripheral board 120, and the signal interface board 180 are respectively connected to the ETH switching bus 137.

[0056] The signal interface board 180 is connected to the first power line 133 and the second power line 135 respectively.

[0057] The backplane 130 communicates with the main control board 110, the shaft temperature acquisition sensor 150, and the acceleration sensor 160 via the RS485 bus 131.

[0058] The backplane 130 transmits the second power output from the power board 140 to the main control board 110, the peripheral board 120 and the power distribution board 170 via the second power line 135;

[0059] The peripheral board 120 is used for storing data and for collecting data.

[0060] It should be noted that this application uses a main control board 110 to perform coordinated control of the entire machine. The main control board 110 has the following functions:

[0061] 1. 100M real-time + maintenance Ethernet;

[0062] 3. At least 12 DIP switches are required to set the vehicle model and license plate number (which can be obtained from the MVB board or other boards);

[0063] 4. The RTC (Real-Time Clock) is stored for at least 15 days.

[0064] The main control board 110 is connected to the second power line 135 via I2C to monitor the power supply voltage so as to provide timely alarm and handling in case of fault.

[0065] Optionally, the main control board 110 integrates a processor.

[0066] The processor, as the control center of the bogie safety inspection general system 100, can be a single processor or a collective term for multiple processing elements. For example, the processor can be one or more central processing units (CPUs), other general-purpose processors, application-specific integrated circuits (ASICs), or one or more integrated circuits configured to implement the embodiments of this application, such as one or more digital signal processors (DSPs), or one or more field-programmable gate arrays (FPGAs) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general-purpose processor can be a microprocessor or any conventional processor.

[0067] Alternatively, the processor can perform various functions of the bogie safety inspection general system 100 by running or executing the software program therein.

[0068] In a specific implementation, as one example, the processor may include one or more CPUs, such as CPU0 and CPU1.

[0069] In a specific implementation, as one example, the main control board 110 may also include multiple processors, each of which may be a single-core processor (single-CPU) or a multi-core processor (multi-CPU). Here, a processor may refer to one or more devices, circuits, and / or processing cores used to process data (e.g., computer program instructions).

[0070] In the above implementation process, the main control board 110, peripheral board 120, backplane 130, power board 140 and signal interface board 180 are integrated to use the ETH switching bus 137 for data communication. The signal interface board 180 is used for wired data acquisition and the peripheral board 120 is used for wireless data acquisition to collect data from multiple sensors. This constructs a universal bogie safety detection system, which facilitates the interchangeability of plug-ins between different bogie detection devices to ensure compatibility with different bogie detection devices.

[0071] The peripheral board 120 stores data and is used to collect data wirelessly.

[0072] In one possible embodiment, the peripheral board 120 includes: a switching board 121, an MVB communication board 123, and a storage board 125.

[0073] The switching board 121, the MVB (Multi-function Vehicle Bus) communication board 123, and the storage board 125 are all connected to the RS485 bus.

[0074] The switching board 121, the MVB communication board 123, and the storage board 125 are respectively connected to the ETH switching bus 137.

[0075] Optionally, the switching board 121 is an ECN switching plug-in.

[0076] Optionally, a memory is integrated on the storage board 125. The memory can have a storage capacity of 64GB to meet the needs of wireless sensing-based shaft temperature, instability, and stability applications.

[0077] Of course, in actual use, the storage board 125 can be expanded with a large-capacity storage card to expand the storage function to 1TB or more, in order to store the data collected during the process and fault data.

[0078] Optionally, the memory may be non-volatile memory. This non-volatile memory may be read-only memory (ROM), programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), or flash memory. Alternatively, the memory may also be a compact disc read-only memory (CD-ROM) or other optical disc storage, optical disc storage (including compressed discs, laser discs, optical discs, digital universal discs, Blu-ray discs, etc.), magnetic disk storage media, or other magnetic storage devices, or any other medium capable of carrying or storing desired program code in the form of instructions or data structures that can be accessed by a computer, but is not limited thereto.

[0079] In one possible embodiment, the peripheral board 120 further includes a wireless communication board 129.

[0080] The wireless communication board 129 is connected to the ETH switching bus 137;

[0081] The wireless communication board 129 is also connected to the second power line 135.

[0082] The wireless communication board 129 is used to collect data sent by sensors (such as shaft temperature acquisition sensors and acceleration sensors) that are in wireless communication mode.

[0083] The power distribution board 170 is connected to the main control board 110 and the power supply board 140 respectively, and the power distribution board 170 is used to supply power to the sensor in wireless communication mode.

[0084] Optionally, the wireless communication board 129 integrates a WiFi (Wireless Fidelity, IEEE 802.11 series wireless local area network) function module.

[0085] For example, the bogie safety detection general system 100 can collect sensor data via Wi-Fi communication on the wireless communication board 129, and then send the data to the main control board 110 via the ETH exchange bus 137 on the backplane 130.

[0086] Optionally, to ensure the security and stability of the Wi-Fi sensor network, the SSID, password, and operating channel of the Wi-Fi network need to be processed accordingly.

[0087] Normal operation: After the main control board 110 is powered on, it hands with the wireless communication board 129 and sends information such as vehicle model and license plate number to the wireless communication board 129. Based on the received vehicle model and license plate number information, the wireless communication board 129 calculates the SSID, password and channel (the working channel is selected to be a channel that does not affect each other, such as 1 / 6 / 11) according to the pre-set algorithm, and then stores and starts the Wi-Fi network.

[0088] Maintenance and Operation: When the bogie safety monitoring system 100 requires specific maintenance, such as initial installation or sensor replacement (e.g., shaft temperature sensor, acceleration sensor), the host can be set to maintenance mode via FTP. In maintenance mode, the main control board 110 sends a maintenance mode command to the wireless communication board 129, forcing the wireless communication board 129 to broadcast the default SSID and password. Sensors come with default SSID connection data from the factory and will automatically connect to this wireless network when no higher-priority normal operating network is available. After the sensor connects to this network, the PTU can view all sensor device information, such as serial number, installation location, sensor manufacturer, and sensor type. The PTU can individually or in batches set the sensor location information, store the sensor location information in the sensor, or download and package all the above information to generate a configuration file.

[0089] Optionally, the backplane 130 can be configured with an RS485 bus 131 and an ETH exchange bus 137 to enable data interaction between master and slave boards and between master control boards of different systems.

[0090] In addition, the power supply between the power board 140 and the other components is realized by setting a first power line 133 and a second power line 135 on the back panel 130.

[0091] In the above implementation process, by setting RS485 bus 131, first power line 133, second power line 135 and ETH switching bus 137 on the backplane 130, the complexity of the wiring can be reduced and mutual interference between the wiring can be avoided.

[0092] Optionally, the power board 140 includes a first DC / DC converter 141.

[0093] The first DC / DC converter 141 is connected to the first power line 133 and the second power line 135 respectively.

[0094] The first DC / DC converter 141 is used to convert the external input power supply into the first power supply and the second power supply.

[0095] Optionally, the first power supply is 5V and the second power supply is 24V.

[0096] In other words, in this application, the first DC / DC converter 141 converts the 110V external input power supply to 5V and 24V, and then outputs them to the first power line 133 and the second power line 135 respectively, so that the backplane 130 provides an energy transmission loop for use by various components.

[0097] Optionally, the first DC / DC converter 141 includes a first sub-converter and a second sub-converter;

[0098] The input terminal of the first sub-converter is connected to an external power supply, the output terminal of the first sub-converter is connected to the input terminal of the second sub-converter and the second power supply line 135, and the output terminal of the second sub-converter is connected to the first power supply line 133.

[0099] Optionally, the first sub-converter is used to convert the 110V external input power supply to a 24V second power supply and output the 24V second power supply to the input terminal of the second sub-converter and the second power supply line 135; the second sub-converter is used to convert the input 24V second power supply to a 5V first power supply and input the 5V first power supply to the first power supply line 133.

[0100] Optionally, the number of power supply boards 140 can be multiple. Multiple power supply boards 140 can form a power redundancy architecture. No specific limitation is made here.

[0101] Optionally, the power board 140 includes redundant power supply modules, such as two power supply modules (each power supply module includes a first DC / DC converter 141), for example. Figure 3 As shown, both power supply modules supply power simultaneously, but the backup power supply module is in no-load mode. When the backup power supply module detects that the output voltage of the main power supply module is lower than the rated value, it switches to the control system to supply power.

[0102] It should be noted that the primary and backup power supply configurations can be set according to the actual situation, and no specific restrictions are made here.

[0103] Optionally, the distribution board 170 includes a second DC / DC converter 171;

[0104] The input terminal of the second DC / DC converter 171 is connected to the first DC / DC converter 141 for transmitting external power to the second DC / DC converter 171;

[0105] The output of the second DC / DC converter 171 is used to connect to the sensor in wireless communication mode.

[0106] Optionally, the output of the second DC / DC converter 171 is 24V.

[0107] Optionally, the distribution board 170 may also include an output monitoring module, an output protection module, a disconnection detection module, and an interface group power supply module.

[0108] The output monitoring module is used to monitor the total output voltage, total output current, and power distribution port output current.

[0109] The output protection module includes overvoltage protection, overcurrent protection, and short-circuit protection. Configurable information for the output protection module includes, but is not limited to, overcurrent thresholds, overvoltage thresholds, and short-circuit thresholds.

[0110] Among them, the disconnection detection module is used to disconnect one side of the ring network in a certain road according to the control requirements of the main control board 110 before the vehicle leaves the warehouse after the power distribution is normal and the sensor is working properly. It can determine whether there is a disconnection in the sensor power supply ring network by checking the sensor and the power output current.

[0111] The interface group power supply module is used to prevent all sensors from losing power due to short circuits in the sensor power interfaces, which would trigger the power distribution board protection.

[0112] Optionally, the distribution board 170 provides an I2C interface to connect to the main control board 110.

[0113] It should be noted that this application supports both wireless power supply and wired power supply for wireless sensing, but no specific limitations are made here.

[0114] Taking wired power supply for wireless sensing as an example, the wireless sensor host uses a power distribution board 170 as the wired power distribution interface for the sensor. Internally, it includes an isolated DC / DC 110V to 24V converter (110V is drawn from the back panel), providing an isolation voltage of over AC1000V. External power is supplied via 2 / 4 M12 (A code) interfaces (not limited to this single interface method), using a parallel-connected output power supply. The sensor power supply in wireless communication mode forms a ring power supply network, with the sensor power input interface at position 1 split into 2.

[0115] The signal interface board 180 is used to acquire data from multiple sensors via a wired acquisition method.

[0116] Optionally, the signal interface board 180 includes a shaft temperature acquisition board 181, a stable acquisition board 182, an unstable acquisition board 183, and a vibration temperature acquisition board 184.

[0117] Shaft temperature acquisition board 181, stable acquisition board 182, unstable acquisition board 183 and vibration temperature acquisition board 184 are respectively connected to the first power line 133, the second power line 135, the RS485 bus 131 and the ETH switching bus 137.

[0118] The axle temperature acquisition board 181 is used to acquire the axle temperature signal of the vehicle. For example, the axle temperature acquisition board 181 is used to acquire the temperature signal fed back by the PT100 temperature sensor. Specifically, the axle temperature signal of the vehicle is acquired periodically using a sampling rate greater than or equal to 40Hz. At this time, the main control board 110 and the storage board 125 can acquire the axle temperature signal through the ETH exchange bus 137.

[0119] The stable acquisition board 182 is used to acquire the vehicle's three-axis acceleration signal. For example, the stable acquisition board 182 can be used to acquire the three-axis acceleration signal acquired by the acceleration sensor, such as using a sampling rate greater than or equal to 512Hz to periodically acquire the vehicle's acceleration signal. At this time, the main control board 110 and the storage board 125 can acquire the acceleration signal through the ETH exchange bus 137.

[0120] The unstable acquisition board 183 is used to acquire the single-axis acceleration signal of the vehicle.

[0121] The vibration and temperature acquisition board 184 is used to acquire vibration and temperature signals from the vehicle. For example, the vibration and temperature acquisition board 184 can be used to acquire vibration and temperature signals collected by vibration sensors and temperature sensors, respectively.

[0122] For example, a vibration sensor can periodically acquire vibration acceleration signals using a sampling rate of 50 kHz or higher; while a temperature sensor can periodically acquire temperature signals using a sampling rate of 3 Hz.

[0123] At this time, the main control board 110 and the storage board 125 acquire the vibration acceleration signal and the temperature signal through the ETH exchange bus 137.

[0124] Optionally, the vibration sensor is an IEPE type sensor.

[0125] Optionally, the temperature sensor is a PT1000 temperature sensor.

[0126] It should be understood that the shaft temperature acquisition board 181, the stable acquisition board 182, the unstable acquisition board 183, and the vibration temperature acquisition board 184 are used to acquire the data returned by the sensor through a wired connection to the sensor.

[0127] Optionally, the signal interface board 180 also includes an I / O board 186, which provides an I / O interface to facilitate the acquisition of information or the output of data.

[0128] The IO board is connected to the RS485 bus 131 and the first power line 133, respectively.

[0129] It should be noted that the IO board 186 uses a 110V level interface digital signal to acquire external status information. It can use relay contacts or MOSFETs as digital output signals to drive external loads or connect to a safety loop.

[0130] It should be noted that in this application, data can be collected either by using the signal interface board 180 to achieve a wired connection between the sensor and the data acquisition method, or by using the peripheral board 120 to achieve a wireless connection between the sensor and the data acquisition method.

[0131] In summary, combining Figures 1 to 3 As shown in the general bogie safety testing system, the main control board 110, peripheral board 120, backplane 130, power board 140 and signal interface board 180 are integrated. The system uses the ETH switching bus 137 for data communication and the signal interface board 180 for wired data acquisition and the peripheral board 120 for wireless data acquisition to collect data from multiple sensors. This constructs a general bogie safety testing system that facilitates the interchangeability of plug-ins between different bogie testing devices to ensure compatibility with different bogie testing devices.
