Description

Technical Field

[0001] This utility model relates to the field of CPR battery voltage measurement technology, and more specifically, to a CPR battery voltage measurement device for a WD-32 stability vehicle. Background Technology

[0002] The CPR battery in the Dynamic Stability Vehicle primarily powers the CPR computer and three-phase equipment in the front driver's cab. However, this battery currently lacks a voltage display; if it fails to charge, the CPR system and three-phase equipment will malfunction. Therefore, it is essential to measure and monitor the CPR battery voltage in real time.

[0003] Therefore, designing a WD-32 stabilizer car CPR battery voltage measurement device to monitor the CPR battery voltage in real time by installing a voltmeter on the CPR battery, and ensuring the normal operation of power supply facilities and equipment related to the CPR battery, is an urgent problem to be solved. Utility Model Content

[0004] The purpose of this invention is to provide a voltage measuring device for the CPR battery of the WD-32 stabilizer vehicle. This device measures the voltage value in real time by installing a voltmeter on the CPR battery and uses a pressure monitoring unit to analyze the rationality of pressure monitoring, thereby ensuring that the CPR battery can work stably and effectively for a long time.

[0005] In a first aspect, this utility model provides a WD-32 stabilizer car CPR battery voltage measuring device, comprising: a voltmeter, installed on an NPR battery, for measuring the voltage of the CPR battery; and a pressure monitoring unit, connected to the voltmeter, for acquiring voltage data of the CPR battery from the voltmeter and performing pressure monitoring analysis to generate pressure monitoring result data.

[0006] In this invention, the device measures the voltage value in real time by installing a voltmeter on the CPR battery and analyzes the rationality of pressure monitoring using a pressure monitoring unit, thereby ensuring that the CPR battery can work stably and effectively for a long time.

[0007] As one possible implementation, the maximum range of the voltmeter should not be less than the maximum voltage of the CPR battery.

[0008] In this invention, the range of the voltmeter needs to ensure that the entire range of voltage changes of the CPR battery is measured, and to avoid damage to the voltmeter caused by an excessively small range.

[0009] As one possible implementation, the ratio of the voltmeter's maximum range to the CPR battery's maximum voltage is 3:2.

[0010] In this invention, the maximum voltage of the battery is located at two-thirds of the maximum range of the voltmeter to ensure a certain level of measurement accuracy.

[0011] As one possible implementation, the CPR battery voltage is connected to the electrical equipment via a power key switch, one end of the pressure gauge is connected to one end of the CPR battery on the power key switch, and the other end is grounded.

[0012] In this invention, the connection between the CRP, the voltmeter, and the electrical equipment is achieved through a power key switch. Therefore, the power supply control of the CRP can also be achieved through the power key switch, resulting in a more convenient power control effect for the CRP.

[0013] As one possible implementation, the power key switch includes a first terminal, a second terminal, and a key reversing device; the first terminal is connected to the CPR battery; the second terminal is connected to the electrical equipment; the key reversing device is rotatably disposed between the first terminal and the second terminal, and the key reversing device is controlled by a switch key to achieve contact and disconnection with the first terminal and the second terminal; one end of the voltmeter is connected to the first terminal.

[0014] In this utility model, power key switches come in various forms. The power key switch provided in this application has a simple structure, and all wiring is connected to the corresponding terminals, reducing the internal wiring of the switch and lowering the complexity of the internal wiring. It also ensures a stable connection.

[0015] As one possible implementation, the key reversing device includes a rotating cylinder and contact points; one end of the rotating cylinder has a keyhole along the axial direction, and the shape and size of the keyhole match the shape and size of the switch key; contact heads are arranged opposite each other on the outer wall surface of the rotating cylinder, and the position of the contact heads on the rotating cylinder is adapted to the position of the first terminal and the second terminal.

[0016] This invention provides a specific key reversing device structure. The key reversing device has two main functions: first, it allows the key to rotate, enabling electrical connection and disconnection control of the reversing device; second, the rotation of the reversing device ensures reliable electrical connection and disconnection of the wiring terminals. Stable connection and disconnection with the wiring terminals are achieved by setting contact points on the rotating cylinder. The rotating cylinder acts as a carrier for key control, completing the key's command control.

[0017] As one possible implementation, the outer surface of the rotating cylinder is covered with a conductive layer; the contact head is connected to the conductive layer.

[0018] In this invention, of course, to achieve the connection and disconnection control of the key to the rotating cylinder, it is necessary to ensure that the rotating cylinder is conductive.

[0019] As one possible implementation, the contact head includes a connecting base and a contact piece; one end of the connecting base is connected to the conductive layer, and the other end is connected to the contact piece; a first connecting groove is formed on the first terminal; the shape and size of the contact piece are adapted to the shape and size of the first connecting groove; a second connecting groove is formed on the second terminal, and the shape and size of the contact piece are adapted to the shape and size of the second connecting groove.

[0020] In this utility model, there are various ways to connect the contact head and the terminal block. The contact head and the terminal block provided in this application are in surface contact, which increases the contact area on the one hand and maintains a stable electrical connection on the other.

[0021] As one possible implementation, the depth of the keyhole on the rotating cylinder exceeds half the length of the rotating cylinder along its axial direction.

[0022] In this invention, the depth of the keyhole affects the service life of the rotating cylinder driven by the key to a certain extent, and a relatively deep keyhole can improve the reliability of use.

[0023] As one possible implementation, the depth of the keyhole on the rotating cylinder is 2 / 3 of the length of the rotating cylinder along the axial direction.

[0024] In this invention, a suitable keyhole depth is provided, at which the reliability of rotating cylinder is improved.

[0025] The beneficial effects of the WD-32 stabilizer car CPR battery voltage measuring device provided by this utility model are as follows:

[0026] This device measures the voltage in real time by installing a voltmeter on the CPR battery and uses a pressure monitoring unit to analyze the rationality of pressure monitoring, ensuring that the CPR battery can work stably and effectively for a long time. Attached Figure Description

It should be understood that the following drawings only show some embodiments of this utility model and should not be regarded as a limitation on the scope.

[0030] The technical solutions of the present invention will now be described with reference to the accompanying drawings in the embodiments of the present invention.

[0031] The CPR battery in the Dynamic Stability Vehicle primarily powers the CPR computer and three-phase equipment in the front driver's cab. However, this battery currently lacks a voltage display; if it fails to charge, the CPR system and three-phase equipment will malfunction. Therefore, it is essential to measure and monitor the CPR battery voltage in real time.

[0032] refer to Figure 1 This utility model embodiment provides a WD-32 stabilizer car CPR battery voltage measuring device, which includes: a voltmeter, installed on the NPR battery, for measuring the voltage of the CPR battery; and a pressure monitoring unit, connected to the voltmeter, for acquiring the voltage data of the CPR battery from the voltmeter, and performing pressure monitoring analysis to generate pressure monitoring result data.

[0033] This device measures the voltage in real time by installing a voltmeter on the CPR battery and uses a pressure monitoring unit to analyze the rationality of pressure monitoring, ensuring that the CPR battery can work stably and effectively for a long time.

[0034] The voltmeter's maximum range should not be less than the maximum voltage of the CPR battery. The voltmeter's range needs to ensure that the entire voltage range of the CPR battery is measured, while avoiding damage to the voltmeter due to an excessively small range. Preferably, the ratio of the voltmeter's maximum range to the CPR battery's maximum voltage is 3:2. Positioning the battery's maximum voltage at two-thirds of the voltmeter's maximum range ensures a certain level of measurement accuracy.

[0035] Specifically, the CPR battery voltage is connected to the electrical equipment via a power key switch. One end of the pressure gauge is connected to the end of the CPR battery connected to the power key switch, and the other end is grounded. The connection between the CPR, the voltmeter, and the electrical equipment is achieved through the power key switch; therefore, the power supply to the CPR can also be controlled by the power key switch, achieving a more convenient power control effect for the CPR.

[0036] The power key switch includes a first terminal, a second terminal, and a key reversing device. The first terminal is connected to the CPR battery. The second terminal is connected to the electrical equipment. The key reversing device is rotatably positioned between the first and second terminals, and its rotation is controlled by a switch key to achieve contact and disconnection with the first and second terminals. One end of a voltmeter is connected to the first terminal. Power key switches come in various forms, but the power key switch provided in this application has a simple structure, and all wiring is connected to the corresponding terminals, reducing internal wiring complexity and ensuring a stable connection.

[0037] The key reversing device includes a rotating cylinder and contact points. One end of the rotating cylinder has a keyhole axially formed, the shape and size of which match the shape and size of the switch key. Contact heads are positioned opposite each other on the outer wall of the rotating cylinder, their positions corresponding to the positions of the first and second wiring terminals. The key reversing device has two main functions: first, to allow the key to rotate, enabling electrical connection and disconnection control of the reversing device; and second, to ensure proper electrical connection and disconnection of the wiring terminals through rotation. By setting contact points on the rotating cylinder, stable connection and disconnection with the wiring terminals are achieved. The rotating cylinder, as the carrier of the key control, completes the key's command control.

[0038] The outer surface of the rotating cylinder is covered with a conductive layer; the contact head is connected to the conductive layer. Of course, to achieve the connection and disconnection control of the rotating cylinder by the key, the rotating cylinder must be conductive.

[0039] The contact head includes a connecting base and a contact piece; one end of the connecting base is connected to a conductive layer, and the other end is connected to the contact piece; a first connecting groove is formed on the first terminal; the shape and size of the contact piece are adapted to the shape and size of the first connecting groove; a second connecting groove is formed on the second terminal, and the shape and size of the contact piece are adapted to the shape and size of the second connecting groove. The connection method between the contact head and the terminal is diverse. The contact head and terminal provided in this application use surface contact, which increases the contact area and maintains a stable electrical connection.

[0040] The depth of the keyhole on the rotating cylinder exceeds half the length of the rotating cylinder along its axial direction. The depth of the keyhole affects the service life of the rotating cylinder driven by the key to some extent; a relatively deep keyhole can improve the reliability of use. Preferably, the depth of the keyhole on the rotating cylinder is 2 / 3 of the length of the rotating cylinder along its axial direction. At this depth, the reliability of the rotating cylinder is improved.

[0041] The pressure monitoring unit in this device specifically includes the following steps:

[0042] S1: Obtain the real-time operating voltage value during operation, perform operating voltage monitoring and analysis, and generate operating voltage monitoring result information.

[0043] Pressure monitoring of CPR batteries mainly includes two aspects: real-time voltage monitoring during CPR operation and real-time voltage monitoring during charging. These two aspects of monitoring effectively ensure the long-term stable operation of the CPR battery.

[0044] The system acquires real-time operating voltage values ​​during operations and performs operating voltage monitoring and analysis to generate operating voltage monitoring results information. This includes: setting the allowable rate of change of operating voltage, acquiring real-time operating voltage values, performing operating voltage change rate monitoring and analysis, and generating operating voltage change rate monitoring and analysis results information; setting the minimum voltage limit value, acquiring real-time operating voltage values, performing operating voltage value monitoring and analysis, and generating operating voltage value monitoring and analysis results information; and combining the operating voltage change rate monitoring and analysis results information with the operating voltage value monitoring and analysis results information to generate operating voltage monitoring information.

[0045] The analysis of the working voltage of CPR batteries includes two aspects. One is that there may be short-term exceedances during operation. This exceedance analysis is determined by the voltage fluctuations during operation. The other aspect is the over-limit of the working voltage. Once the limit is exceeded, it will cause a certain degree of damage to the battery.

[0046] The permissible voltage change rate is set, and real-time operating voltage values ​​are acquired. Voltage change rate monitoring and analysis are performed to generate monitoring and analysis results, including: acquiring real-time operating voltage values ​​and establishing a real-time voltage change function that changes sequentially over time; determining the real-time voltage change rate function based on the real-time voltage change function; and performing the following rate monitoring and analysis based on the permissible voltage change rate and the real-time voltage change rate function: if no real-time voltage change rate exceeds the permissible voltage change rate in the real-time voltage change rate function, normal voltage change rate information is generated; if a real-time voltage change rate exceeds the permissible voltage change rate in the real-time voltage change rate function, and the continuous duration of this exceedance does not exceed the abnormal change rate time limit, normal voltage change rate information is generated; if a real-time voltage change rate exceeds the permissible voltage change rate in the real-time voltage change rate function, and the continuous duration of this exceedance does not exceed the abnormal change rate time limit, normal voltage change rate information is generated.

[0047] Regarding the monitoring and analysis of the rate of change during real-time operations, there are three main scenarios: First, the real-time rate of change does not exceed the set value throughout the entire operation. Second, there may be isolated instances where the real-time rate of change exceeds the limit, but the duration of the exceedance is inconsistent. Third, there may be instances where the real-time rate of change exceeds the limit for an extended period. Of course, the permissible rate of change for voltage operations can be determined based on actual needs or through big data analysis.

[0048] Set a minimum voltage limit and acquire real-time operating voltage values. Perform operating voltage value monitoring and analysis to generate operating voltage value monitoring and analysis results, including: acquiring real-time operating voltage values, setting an allowable deviation coefficient, and performing the following operating voltage value monitoring and analysis: if the real-time operating voltage value does not reach the product of the minimum voltage limit and the allowable deviation coefficient, then operating voltage normal information is generated; if the real-time operating voltage value reaches the product of the minimum voltage limit and the allowable deviation coefficient, then operating voltage abnormal information is generated.

[0049] Real-time voltage monitoring primarily aims to determine whether the acquired voltage value has approached the minimum voltage limit. It's important to note that directly using the minimum voltage limit as the criterion without providing a certain allowable capacity may lead to battery damage due to the waiting time before control and adjustment are initiated after the limit has been reached.

[0050] S2: Obtain the real-time charging voltage value during charging, perform charging voltage monitoring and analysis, and generate charging voltage monitoring result information.

[0051] The system acquires real-time charging voltage values ​​during charging and performs charging voltage monitoring and analysis to generate charging voltage monitoring results. These results include: setting an allowable rate of change in charging voltage, acquiring real-time charging voltage values, performing charging voltage rate of change monitoring and analysis, and generating charging voltage rate of change monitoring and analysis results; setting a minimum voltage limit value, acquiring real-time charging voltage values, performing charging voltage value monitoring and analysis, and generating charging voltage value monitoring and analysis results; and combining the charging voltage rate of change monitoring and analysis results with the charging voltage value monitoring and analysis results to generate charging voltage monitoring information.

[0052] Similarly, battery monitoring and analysis also involves analyzing and judging the rate of change of voltage and the real-time voltage value during charging. By using these two different aspects, abnormal battery problems can be effectively detected during the charging process, and reasonable responses can be made.

[0053] A permissible rate of change for charging voltage is set, and real-time charging voltage values ​​are acquired. Charging voltage rate of change monitoring and analysis are performed to generate charging voltage rate of change monitoring and analysis results, including: acquiring real-time charging voltage values ​​and establishing a real-time change function for charging voltage values ​​that changes sequentially over time; determining the real-time rate of change function for charging voltage values ​​based on the real-time change function; and performing the following rate of change monitoring and analysis based on the permissible rate of change for charging voltage and the real-time rate of change function for charging voltage values: if no real-time rate of change for charging voltage values ​​exceeds the permissible rate of change for charging voltage values ​​in the real-time rate of change function, then normal charging voltage rate of change information is generated; if a real-time rate of change for charging voltage values ​​exceeds the permissible rate of change for charging voltage values ​​in the real-time rate of change function, and the continuous time duration exceeding the permissible rate of change does not exceed the abnormal time limit value, then normal charging voltage rate of change information is generated; if a real-time rate of change for charging voltage values ​​exceeds the permissible rate of change for charging voltage values ​​in the real-time rate of change function, and the continuous time duration exceeding the permissible rate of change does not exceed the abnormal time limit value, then normal charging voltage rate of change information is generated.

[0054] Voltage monitoring and analysis of the charging rate of change during charging still reveals several scenarios, including partial exceedance of the charging voltage change rate, partial exceedance within the allowable time, and complete exceedance. This system can fully cover all scenarios related to the charging voltage change rate. Similarly, the allowable voltage change rate can be set according to actual needs or determined based on large datasets.

[0055] Set a minimum voltage limit and acquire real-time charging voltage values. Perform charging voltage value monitoring and analysis to generate charging voltage value monitoring and analysis results, including: acquiring real-time charging voltage values, setting an allowable deviation coefficient, and performing the following charging voltage value monitoring and analysis: if the real-time charging voltage value does not reach the product of the minimum voltage limit and the allowable deviation coefficient, then normal charging voltage information is generated; if the real-time charging voltage value reaches the product of the minimum voltage limit and the allowable deviation coefficient, then abnormal charging voltage information is generated.

[0056] Monitoring battery voltage information during charging also includes monitoring whether the voltage value is within a reasonable range. The product of the minimum charging voltage limit and the allowable deviation coefficient is used as the basis for comparison and judgment of the charging voltage value, so as to ensure that a rapid determination can be made when abnormal battery charging is detected.

[0057] In summary, the beneficial effects of the WD-32 stabilizer car CPR battery voltage measuring device provided in this embodiment of the invention are as follows:

[0058] This device measures the voltage in real time by installing a voltmeter on the CPR battery and uses a pressure monitoring unit to analyze the rationality of pressure monitoring, ensuring that the CPR battery can work stably and effectively for a long time.

It can also instruct only a part of the information to be instructed, while the other parts are known or pre-agreed upon.
