Description

Technical Field

[0001] This application relates to the field of energy storage measurement technology, specifically to a system for measuring the PV characteristics of ABS energy storage devices. Background Technology

[0002] In active safety braking systems such as anti-lock braking systems (ABS) and electronic stability control (ESC), accumulators provide a depressurized hydraulic fluid storage space to prevent wheel lock-up, and also replenish the hydraulic pressure during system pressurization. Currently, in the early stages of development, the PV characteristic parameters of accumulators can only be indirectly obtained through theoretical calculations of some parameters. Because these calculations are indirect, the resulting PV characteristics may have significant errors, and human error could even lead to completely incorrect parameter relationships. Therefore, the calculation of accumulator PV characteristic parameters is currently quite cumbersome and requires improvement in accuracy. Utility Model Content

[0010] In some embodiments of this application, the energy storage device includes an energy storage spring, and the displacement sensor is located on the side of the energy storage spring away from the pressure regulating valve.

[0011] In some embodiments of this application, the ABS accumulator PV characteristic measurement system further includes a displacement dial gauge, which is located on the side of the accumulator spring away from the pressure regulating valve, and the displacement dial gauge is signal-connected to the processor.

[0012] In some embodiments of this application, the ABS accumulator PV characteristic measurement system further includes an environmental simulation chamber, in which the accumulator and the displacement sensor are both located. The environmental simulation chamber is used to simulate the temperature, humidity, and air pressure of the environment in which the accumulator is located.

[0013] In some embodiments of this application, the environmental simulation chamber includes a chamber body, a temperature control module, a humidity control module, a pressure control module, and a sensing and monitoring module. The energy storage device and the displacement sensor are both located inside the chamber body. The temperature control module, the humidity control module, the pressure control module, and the sensing and monitoring module are all located on the inner wall of the chamber body. Furthermore, the temperature control module, the humidity control module, the pressure control module, and the sensing and monitoring module are all signal-connected to the processor. The sensing and monitoring module is used to monitor the temperature, humidity, and pressure parameters inside the chamber body in real time.

[0014] In some embodiments of this application, the pressure regulating valve is located outside the chamber, and the pressure regulating valve is connected to the accumulator via a high-pressure hose.

[0015] In some embodiments of this application, there are multiple pressure regulating valves, accumulators, and displacement sensors. Multiple pressure regulating valves are located outside the chamber, and multiple accumulators and multiple displacement sensors are located inside the chamber. Each pressure regulating valve, accumulator, and displacement sensor corresponds to another, and each pressure regulating valve, accumulator, and displacement sensor constitutes an accumulator measurement unit.

[0016] In some embodiments of this application, the pressure source includes multiple pressure output ports, each of which is connected to one of the energy storage measurement units, and the multiple energy storage measurement units are connected in parallel.

[0017] In some embodiments of this application, the surface of the chamber is provided with a data transmission interface and multiple control interfaces.

The safety protection module is connected to the sensing and monitoring module, the temperature control module, and the pressure control module. It is used to receive temperature and pressure data monitored by the sensing and monitoring module and selectively control the emergency shutdown of the temperature control module and the pressure control module.

[0019] Therefore, the embodiments of this application achieve accurate measurement of the PV characteristics of the accumulator through the cooperation of a pressure regulating valve and a displacement sensor. Specifically, a pressure source provides the accumulator with the required measurement pressure. A pressure regulating valve is installed between the pressure source and the accumulator to regulate the pressure output from the pressure source to the accumulator, ensuring that the accumulator continuously receives gradually changing pressure. This prevents the accumulator from being affected by sudden pressure changes, which could impact the accuracy of the PV characteristic measurement. Then, a displacement sensor monitors the displacement of the piston in the accumulator in real time and transmits the displacement to a processor. The pressure from the pressure regulating valve to the accumulator is also transmitted to the processor in real time. The processor correlates the pressure and displacement and plots a PV characteristic graph based on the relationship between the pressure and displacement, thus achieving accurate measurement of the PV characteristics of the ABS accumulator.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or specifying the number of technical features indicated. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0027] Please see Figure 1 and Figure 2 The embodiments of this application provide an ABS accumulator PV characteristic measurement system, including a pressure source 1, a pressure regulating valve 2, an accumulator 3, a displacement sensor 4, and a processor 5.

[0028] The pressure regulating valve 2 is connected to the output end of the pressure source 1. The accumulator 3 is connected to the output end of the pressure regulating valve 2. The displacement sensor 4 is located on one side of the piston's movement path in the accumulator 3. The processor 5 is connected to the pressure regulating valve 2 and the displacement sensor 4, receives data from the pressure regulating valve 2 and the displacement sensor 4, and plots the PV characteristic diagram based on the data.

[0029] The technical solution provided in this application achieves accurate measurement of the PV characteristics of the accumulator 3 through the cooperation of a pressure regulating valve 2 and a displacement sensor 4. Specifically, a pressure source 1 provides the accumulator 3 with the required air pressure for measurement. A pressure regulating valve 2 is installed between the pressure source 1 and the accumulator 3 to regulate the air pressure output from the pressure source 1 to the accumulator 3, ensuring that the accumulator 3 continuously receives gradually changing air pressure. This prevents the accumulator 3 from being affected by sudden changes in air pressure, which could impact the accuracy of the PV characteristic measurement. Then, the displacement sensor 4 monitors the displacement of the piston in the accumulator 3 in real time and transmits the displacement to the processor 5. The air pressure transmitted from the pressure regulating valve 2 to the accumulator 3 is also transmitted to the processor 5 in real time. The processor 5 correlates the air pressure and displacement and plots a PV characteristic diagram based on the correspondence between the air pressure and displacement, thus achieving accurate measurement of the PV characteristics of the ABS accumulator 3.

[0030] The specific measurement process is as follows: the air pressure source 1 slowly applies air pressure to the accumulator 3 through the pressure regulating valve 2 until the piston of the accumulator 3 moves to the maximum stroke point, and then slowly reduces the air pressure. The spring of the accumulator 3 pulls the piston to perform the return stroke. This is used to determine the opening pressure point A of the accumulator 3, the working pressure point B when the accumulator 3 is full, the maximum viscous force point C of the accumulator 3, and the pressure point D when the accumulator 3 is empty. The corresponding P-V characteristic curve of the accumulator 3 is plotted to guide the R&D personnel in designing and verifying the accumulator 3 and to determine the friction force of the piston and the spring stiffness of the accumulator 3.

[0031] It should be noted that the opening pressure point A of accumulator 3 refers to the pressure when the piston of accumulator 3 begins to move. The working pressure point B when accumulator 3 is full refers to the pressure when the piston of accumulator 3 moves to its maximum stroke. The maximum viscous force point C of accumulator 3 refers to the initial pressure when the piston of accumulator 3 returns from its maximum stroke point. The pressure point D when accumulator 3 is empty refers to the pressure when accumulator 3 returns to its origin.

[0032] At the same time, displacement sensor 4 monitors the movement and displacement of the piston of accumulator 3, and can also determine the minimum and maximum volume required for accumulator 3 to work, which helps researchers build the correct model in the later algorithm and makes the algorithm more accurate.

[0033] In some embodiments, the accumulator 3 includes an energy storage spring connected to a piston. A displacement sensor 4 is located on the side of the piston away from the energy storage spring, allowing the piston to reciprocate under the action of the energy storage spring and air pressure, thereby obtaining the relationship between piston displacement and air pressure. Positioning the displacement sensor 4 on the side of the piston away from the energy storage spring facilitates direct measurement of the piston's movement, especially for more accurate measurement of the piston's initial position and maximum movement.

[0034] Furthermore, the ABS accumulator PV characteristic measurement system also includes a displacement dial gauge 6. The displacement dial gauge 6 is located on the side of the accumulator spring furthest from the pressure regulating valve 2, and is signal-connected to the processor 5. By utilizing the displacement dial gauge 6 in conjunction with the displacement sensor 4, when the piston is displaced to its maximum displacement, the dial gauge can provide more accurate displacement data. The displacement data from the displacement dial gauge 6 and the displacement data from the displacement sensor 4 are then combined and selected to obtain displacement data accurate to the thousandths of a percent.

[0035] In some embodiments, the ABS accumulator PV characteristic measurement system further includes an environmental simulation chamber 7, in which both the accumulator 3 and the displacement sensor 4 are housed. The environmental simulation chamber 7 is used to simulate the temperature, humidity, and air pressure of the environment in which the accumulator 3 is located. By setting up the environmental simulation chamber 7, the measurement of the accumulator 3 becomes more comprehensive, covering the operating conditions and PV characteristic changes of the accumulator 3 under various environments. For example, if it is necessary to produce an accumulator 3 capable of operating in extremely cold environments, then before production, an extreme cold environment simulation can be performed using the environmental simulation chamber 7 to obtain the PV characteristic curve of the accumulator 3 that can operate normally in extremely cold environments. Researchers can then develop the accumulator 3 specifically for this purpose, improving the applicability of the PV characteristic measurement system for the accumulator 3.

[0036] Furthermore, the environmental simulation chamber 7 includes a chamber body 71, a temperature control module 72, a humidity control module 73, a pressure control module 74, and a sensing and monitoring module 75. The energy storage device 3 and the displacement sensor 4 are both located inside the chamber body 71. The temperature control module 72, the humidity control module 73, the pressure control module 74, and the sensing and monitoring module 75 are all located on the inner wall of the chamber body 71. The temperature control module 72, the humidity control module 73, the pressure control module 74, and the sensing and monitoring module 75 are all connected to the processor 5. The sensing and monitoring module 75 is used to monitor the temperature, humidity, and pressure parameters inside the chamber body 71 in real time.

[0037] Specifically, chamber 71 houses the energy accumulator 3 and displacement sensor 4, providing a controlled, sealed environment. Chamber 71 is made of high- and low-temperature resistant materials to ensure structural stability under varying temperature and humidity conditions. A temperature control module 72, located on the inner wall of chamber 71, precisely regulates the temperature within chamber 71. The temperature control module 72 typically includes a heater and a cooling unit to control the temperature within a set range. Controlled by processor 5, the temperature control module 72 enables gradual temperature adjustment and temperature maintenance. A humidity control module 73, also located on the inner wall of chamber 71, controls the humidity within chamber 71 using humidification and dehumidification devices. The humidity control module 73 can adjust the humidity within a set range of 10%-90% RH to simulate working environments under different humidity conditions. A pressure control module 74 regulates the air pressure inside chamber 71 to simulate pressure changes at different altitudes. This module regulates pressure by increasing or decreasing the gas pressure within chamber 71, typically with an adjustable range from low-pressure to high-pressure environments. The sensing and monitoring module 75 is used to monitor the temperature, humidity, and pressure parameters inside the chamber 71 in real time. This module includes a temperature sensor, a humidity sensor, and a pressure sensor, and can transmit real-time data to the processor 5 for dynamic monitoring and data recording of the test environment. The temperature control module 72, humidity control module 73, pressure control module 74, and sensing and monitoring module 75 are all connected to the processor 5. The processor 5 receives the real-time environmental data collected by the sensing and monitoring module 75 and controls the operation of the temperature control module 72, humidity control module 73, and pressure control module 74 to maintain the set environmental parameters.

[0038] Furthermore, the pressure regulating valve 2 is located outside the chamber 71 to prevent it from being affected by the environment inside the chamber 71. The pressure regulating valve 2 is also connected to the accumulator 3 via a high-pressure hose to ensure stable air pressure transmission between them.

[0039] In some embodiments, there are multiple pressure regulating valves 2, accumulators 3, and displacement sensors 4. Multiple pressure regulating valves 2 are located outside the chamber 71, and multiple accumulators 3 and multiple displacement sensors 4 are located inside the chamber 71. The pressure regulating valves 2, accumulators 3, and displacement sensors 4 correspond one-to-one, and each pressure regulating valve 2, accumulator 3, and displacement sensor 4 constitutes an accumulator 3 measurement unit.

[0040] Specifically, multiple pressure regulating valves 2 are located outside the chamber 71, and each pressure regulating valve 2 is connected to its corresponding accumulator 3 via a high-pressure hose, forming an independent pressure regulation circuit. This helps ensure that each accumulator 3 measurement unit can be tested independently under different pressure conditions, avoiding mutual interference. Multiple accumulators 3 and displacement sensors 4 are all located inside the environmental simulation chamber 7, and a corresponding displacement sensor 4 is installed on the piston movement path of each accumulator 3. The displacement sensors 4 collect real-time piston displacement data under different pressures and transmit the data to the processor 5. Each pressure regulating valve 2, accumulator 3, and displacement sensor 4 constitutes an independent accumulator 3 measurement unit. These measurement units operate in parallel without interference and can run under the same or different test conditions, facilitating synchronous or individual testing of the PV characteristics of different accumulators 3.

[0041] Furthermore, the pressure source 1 includes multiple pressure output ports, each of which is connected to one of the energy storage 3 measurement units, and the multiple energy storage 3 measurement units are connected in parallel.

[0042] Specifically, the pressure source 1 has multiple independent pressure output ports, each connected to its own pressure regulating valve 2 via a high-pressure hose. This ensures that the pressure input of each accumulator 3 measurement unit is completely independent, avoiding pressure fluctuations that may occur when multiple units share a single pressure output port. Multiple accumulator 3 measurement units are connected in parallel via their respective pressure regulating valves 2, independent pressure input ports, accumulators 3, and displacement sensors 4. The pressure regulation and data acquisition of each measurement unit do not interfere with each other, enabling simultaneous operation under different pressure conditions and completing parallel testing of multiple accumulators 3.

[0043] In some embodiments, the surface of the chamber 71 is provided with a data transmission interface and multiple control interfaces. The input end of the data transmission interface is connected to the sensing and monitoring module 75, and the output end of the data transmission interface is connected to the processor 5. The output ends of the multiple control interfaces are respectively connected to the temperature control module 72, the humidity control module 73, and the pressure control module 74, and the input ends of the multiple control interfaces are all connected to the processor 5.

[0044] Specifically, the input end of the data transmission interface is connected to the sensing and monitoring module 75, which is responsible for monitoring parameters such as temperature, humidity, and pressure inside the chamber 71. Through the data transmission interface, this monitoring data can be efficiently transmitted to the processor 5, enabling the system to monitor and record the environmental conditions inside the chamber in real time. The data transmission interface can be a wired interface (such as USB or RS-232) or a wireless interface (such as Wi-Fi or Bluetooth), suitable for different data transmission needs. Users can choose the appropriate connection method according to laboratory conditions. Multiple control interfaces are located on the surface of the chamber 71, used to connect to the control ends of the temperature control module 72, humidity control module 73, and pressure control module 74. The input end of the control interface is connected to the processor 5. Through the control signals issued by the processor 5, the control interface can adjust the operating status of each environmental module, achieving precise control of temperature, humidity, and air pressure inside the chamber 71. Each control interface corresponds one-to-one with each environmental control module, enabling independent control. For example, the processor 5 can adjust the output of the temperature control module 72 independently through the control interface without affecting the operating status of the humidity and pressure control modules 74.

[0045] In some embodiments, a safety protection module is provided inside the chamber 71. The safety protection module is connected to the sensing and monitoring module 75, the temperature control module 72, and the pressure control module 74. It is used to receive temperature and pressure data monitored by the sensing and monitoring module 75 and selectively control the emergency shutdown of the temperature control module 72 and the pressure control module 74.

[0046] Specifically, the safety protection module acquires real-time temperature and pressure data within the chamber 71 via the sensor monitoring module 75. When the temperature or pressure exceeds the set safety range (e.g., temperature exceeding 80°C or pressure exceeding 150 kPa), the safety protection module immediately sends a shutdown command to the temperature control module 72 or pressure control module 74 to stop heating or pressurization, preventing further environmental deterioration. In case of abnormal conditions, the safety protection module selectively controls the emergency shutdown of the temperature control module 72 and pressure control module 74. For example, when the temperature inside the chamber reaches a dangerous level, the safety protection module can shut down the heater of the temperature control module 72 to prevent the temperature from rising further. Similarly, when the pressure inside the chamber 71 exceeds the safety limit, the safety protection module will shut down the pressure control module 74 to stop pressurization, ensuring that the pressure inside the chamber remains within a safe range. To enhance safety, the safety protection module can also be linked to an alarm system, using audible and visual alarms to alert operators to abnormal environmental conditions, requiring immediate system checks or other safety measures.
