Description

Technical Field

[0001] This application relates to the field of vehicle control, and in particular to a method, system and storage medium for controlling train hydraulic braking. Background Technology

[0002] Currently, hydraulic brake electronic control devices are independent complete control cabinets. The cabinet functions to include modules such as speed acquisition, digital input, communication, and storage. These modules are used exclusively, and other electronic control devices in the vehicle also require such common modules. If the brake electronic control device adopts an exclusive mechanism, other electronic control devices must provide these modules themselves. This has resulted in the current situation where multiple devices cannot share common functional modules. Moreover, the trend of lightweighting and integration in rail vehicles is significant, and there is a severe shortage of installation space on many rail vehicles.

[0003] Under current technological conditions, train electrical control is required to be complete and independent, but many rail vehicle models cannot provide a separate chassis for the braking electrical control device. Even if a shared chassis is used, the space left for braking control is severely compressed. Summary of the Invention

When reading, the data is centrally unpacked and parsed to extract the data of the target device and returned to the corresponding target electronic control device.

[0044] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0045] In one embodiment, such as Figure 1 As shown, a train hydraulic braking electronic control method is provided, the method comprising:

[0046] Step 101: Based on the hydraulic braking system architecture of the train, the functional units of the hydraulic braking system are divided into exclusive functional parts and shared functional parts.

[0047] Step 102: Through the exclusive function part and the shared function part, receive relevant commands for vehicle braking, control the hydraulic unit pressure, and apply the basic brakes of the train to complete the braking, release, and anti-skid of the vehicle.

[0048] Step 103: The exclusive function part provides an exclusive mechanism to perform independent function transmission during the control of hydraulic braking;

[0049] Step 104: The shared function part provides a sharing mechanism to perform common braking function transmission.

[0050] The dedicated function portion includes any one or more of the following: accumulator drive function, digital output function, hydraulic regulating valve drive function, and main control function. The shared function portion includes any one or more of the following: speed acquisition function, pressure acquisition function, real-time train communication function, data storage function, digital input function, and power supply function. As the optimal solution, in this embodiment, the dedicated function portion provides a dedicated mechanism for independent function transmission during hydraulic braking control. The dedicated function portion includes providing accumulator drive function, digital output function, hydraulic regulating valve drive function, and main control function. The shared function portion provides a shared mechanism for shared braking function transmission. The shared function portion includes providing speed acquisition function, pressure acquisition function, real-time train communication function, data storage function, digital input function, and power supply function.

[0051] This embodiment structures the entire hydraulic brake electronic control device, dividing it into modules that are dedicated and those that can be shared. The dedicated modules include an accumulator drive unit, a digital output unit, a hydraulic regulating valve drive unit, and a main control unit. The shareable modules include a speed acquisition unit, a pressure acquisition unit, a real-time train communication unit, a data storage unit, a digital input unit, and a power supply unit. Therefore, this embodiment aims to minimize the hardware resources of the electronic control device based on vehicle reliability requirements, which helps solve the problems of insufficient installation space and lightweight design, as well as the rigid issue of reducing material costs. It ensures the integrity and independence of the brake electronic control system while solving the problems of insufficient space and lightweight control devices. Compared to traditional brake electronic control devices, the new shared brake electronic control device is more flexible, with significantly reduced space and weight, and a substantial reduction in cost. The shareable modules can be reasonably adjusted based on actual conditions such as space requirements, reliability requirements, vehicle requirements, and cost requirements. For example, if there is a requirement that the real-time train communication unit be a dedicated module of the hydraulic brake electronic control device, then the real-time train communication unit can be adjusted to be a dedicated module. It can be considered a component of the braking electronic control device or a component of other electronic control devices. Regardless of whether it is part of the braking electronic control device or a component of other electronic control devices, it does not affect the integrity and independence of the braking electronic control system.

[0052] In addition, the shared section contains six functional acquisition modules: speed acquisition, pressure acquisition, real-time train communication, data storage, digital input, and power supply. Similarly, the dedicated section includes accumulator drive, digital output, hydraulic regulating valve drive, and main control functions. For the vehicle's hydraulic braking process, it is through these six functional modules of the shared section that the automatic closed-loop link in the hydraulic braking process is realized.

[0053] In one embodiment, such as Figure 2 As shown, the process for sharing the collected speed data includes the following steps:

[0054] Step 201: Obtain the speed acquisition signal from the speed sensor. The speed acquisition signal is processed by filtering, shaping, speed transmission end isolation and protection circuits, and shared via speed bus or speed hardwire.

[0055] Step 202: The speed bus sharing method is processed by the speed calculation circuit and transmitted in the form of speed values; the speed hardwire sharing method is transmitted in the form of frequency signals.

[0056] Specifically, in the speed acquisition function, speed is first processed, and then acquired. Similarly, the processing logic is similar for pressure acquisition, real-time train communication, data storage, digital input, and power supply during braking. Furthermore, the speed acquisition unit shares the following connection: After the speed sensor signal is filtered, shaped, isolated at the speed transmission end, and processed by protection circuits, for bus-based sharing, it needs to pass through a speed calculation circuit and finally transmit the speed value to other electronic control devices and hydraulic brake control devices; for hard-wired sharing, it does not need to pass through a speed calculation circuit and is finally transmitted as a level signal to other electronic control devices and hydraulic brake control devices, thus achieving speed signal sharing.

[0057] In one embodiment, such as Figure 3 As shown, the process for sharing the acquired pressure data includes:

[0058] Step 301: Obtain pressure acquisition signal from pressure sensor. The pressure acquisition signal is filtered, driven, and protected. The pressure acquisition signal is then processed by proportional adjustment circuit and shared in either pressure bus mode or pressure hard wire mode.

[0059] Step 302: The pressure bus sharing method is processed by AD sampling and pressure calculation circuit, and then transmitted as pressure value; the pressure hard wire sharing method is processed by AD sampling and DA output circuit, and then transmitted as analog voltage or current.

[0060] In one embodiment, the process of the integrated valve executing the braking signal includes: processing the real-time train communication signal through a network transceiver circuit and a data storage circuit, and then exchanging network data with the electronic control device through a multilateral data interaction circuit to form a real-time shared train communication signal.

[0061] Specifically, in the pressure data sharing process, for the bus sharing method, the pressure value is transmitted to other electronic control devices and hydraulic brake electronic control devices through AD sampling and pressure calculation circuit; for the hard-wired sharing method, the pressure value is transmitted to other electronic control devices and hydraulic brake electronic control devices through AD sampling and DA output circuit in the form of analog voltage or current.

[0062] In one embodiment, such as Figure 4 As shown, the process for sharing stored data includes:

[0063] Step 401: After processing by the multilateral data interaction circuit and the data packing and unpacking circuit, and interacting with the electronic control device through the data storage circuit, real-time data sharing is carried out according to the storage requirements of each electronic control device.

[0064] Step 402: The processing of the stored data is based on the needs of each electronic control device. The data of each electronic control device is centrally packaged and stored. When reading, the data is centrally unpacked and parsed to return the data of the target device to the corresponding target electronic control device.

[0065] In one embodiment, such as Figure 5 As shown, sharing of digital inputs includes:

[0066] Step 501: Based on the vehicle DO or status command signal, after filtering and isolation, and processing by the level conversion circuit, it is shared in the form of digital input bus or digital input hardwire.

[0067] Step 502: The digital input bus sharing method is transmitted in data mode after being driven, digital acquisition and bus circuit processing; the digital input hardwire sharing method is transmitted in level mode after being processed by the drive circuit.

[0068] In digital input sharing, for bus sharing, the data is transmitted to other electronic control devices and hydraulic brake control devices via the driver, digital acquisition and bus circuit; for hard-wired sharing, the data is transmitted to other electronic control devices and hydraulic brake control devices via the driver circuit.

[0069] In one embodiment, the power supply unit receives power from the vehicle, converts it to obtain stable voltages for each required voltage, outputs power according to the required capacity of each power source, and then centrally supplies power to each module of each electronic control device, forming a centralized power sharing system. The power supply unit is connected to other modules or systems to provide power. When the power supply unit is used exclusively, it only supplies power to the braking electronic control device and does not supply power to other electronic control devices. When shared, it is allowed to supply power to other electronic control devices.

[0070] It should be understood that although the steps in the flowchart above are shown sequentially as indicated by the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowchart above may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the sub-steps or stages of other steps.

[0074] The dedicated function module 603 is used to provide a dedicated mechanism according to the dedicated function part, and to perform independent function transmission during the control of hydraulic braking;

[0075] The shared function module 604 is used to provide a sharing mechanism based on the shared function part to perform common braking function transmission.

[0076] In one embodiment, the dedicated function module 603 includes any one or more of the following: accumulator drive function, digital output function, hydraulic regulating valve drive function, and main control function; the shared function module 604 includes any one or more of the following: speed acquisition function, pressure acquisition function, real-time train communication function, data storage function, digital input function, and power supply function.

[0077] Specific limitations regarding the train hydraulic brake electronic control system can be found in the limitations of the train hydraulic brake electronic control method described above, and will not be repeated here. Each module in the aforementioned train hydraulic brake electronic control system can be implemented entirely or partially through software, hardware, or a combination thereof. These modules can be embedded in or independent of the processor in a computer device in hardware form, or stored in the memory of a computer device in software form, so that the processor can call and execute the corresponding operations of each module.
