[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0044] Example 1, please refer to Figure 1 As shown, the intelligent monitoring method based on vehicle motor control described in this embodiment includes the following steps:

[0045] Collect monitoring items of vehicle motors;

[0046] Set normal data preset conditions according to the monitoring items of the vehicle motor;

[0050] Acquire abnormal data and obtain verification data according to the verification monitoring plan, determine whether the verification data meets the preset conditions of normal data, and treat the verification data that does not meet the preset conditions of normal data as fault data;

[0051] It is further explained that with the development of society, vehicles are conventional household mobility tools that the public needs to choose. With the introduction of the concept of new energy vehicles, new energy vehicles have developed rapidly and occupied a certain market. Among them, in energy vehicles, vehicle motors are very important. When maintaining the vehicle, the vehicle motor needs to be monitored. The staff needs to set it step by step through the touch screen according to the items to be verified. They cannot leave the operating table, and it is difficult to improve the degree of automation of monitoring the vehicle motor. The operation is not convenient enough, and it is difficult to improve the efficiency of monitoring the vehicle motor. In addition, when abnormal data occurs, it is difficult to verify the data according to the points of the abnormal data, and it is impossible to automatically determine whether the part is abnormal based on the points of the abnormal data. It cannot be used as a judgment, so it is difficult to obtain supporting data for fault determination. Monitoring is guaranteed in this application. The correspondence of data does not require workers to select indicators to correspond to the current monitoring items. They can be directly used to improve the efficiency of operation. The comparative data for vehicle motor monitoring to determine whether it is in a normal state can be directly used as a reference to derive the operating status of the vehicle motor and make preparations for monitoring, which greatly improves the efficiency of data judgment. It can greatly improve the monitoring efficiency of operating data in the process of vehicle motor control, and can be used with one button. There is no need to manually click to change according to the instructions to be simulated. The operation is also more intelligent and simple, which greatly improves the verification efficiency of the indicator status. The verification monitoring plan can be directly called to automatically complete the monitoring of the vehicle motor operating performance, obtain abnormal data, and perform a one-time verification to determine whether the indicator is abnormal, thereby improving the monitoring efficiency of vehicle motor performance.

[0052] In one embodiment, the step of collecting monitoring items of the vehicle motor includes:

[0053] Formulate multiple items of vehicle motor control and multiple indicators of the vehicle motor, wherein the items are control information of the vehicle motor operation;

[0054] Select multiple indicators required for project monitoring, where the multiple indicators are the change data of vehicle motor operation in the project monitoring, and bind the multiple indicators required to the project to obtain the monitoring project;

[0055] It is further explained that before the maintenance and installation of the vehicle motor, the vehicle motor control performance needs to be monitored to determine the stability of the vehicle motor during use. Before monitoring, multiple items of vehicle motor control need to be set, wherein the multiple items include the vehicle motor operating performance during gear shifting control, the vehicle motor operating performance during deceleration or acceleration control, and multiple items such as detecting at what gear position is sudden braking / slow braking, starting in different gears, etc., which are the control information of the vehicle motor operation. Binding multiple indicators and items required to obtain monitoring items can correspond to the indicators required for motor control. Binding, where the indicators include relay status, high-voltage interlock status, resolver signal status, motor temperature status, CAN communication status, controller bus voltage, controller current, motor line voltage, motor line current, motor operation mode, motor operation frequency, motor temperature and controller temperature. Among them, the relay status is divided into total positive relay, total negative relay and pre-charge relay. It is the change data of vehicle motor operation in project monitoring. It can correspond to projects and indicators, facilitate the subsequent display of indicators for projects, ensure the correspondence of monitoring data, and do not require workers to select indicators to correspond to the current monitoring project. It can be directly used to improve the use and operation efficiency.

[0056] In one embodiment, the step of setting the normal data preset conditions according to the monitoring items of the vehicle motor includes:

[0057] Collect the power supply voltage of the vehicle motor;

[0058] Obtaining the multiple indicators corresponding to the monitoring project;

[0059] Setting normal data according to the power supply voltage of the vehicle motor as a normal data preset condition;

[0060] Further explanation: the power supply voltage of the vehicle motor test is collected, and data of multiple indicators of the monitoring items under normal conditions are obtained based on the power supply voltage. The data under normal conditions is used as a normal data preset condition to determine whether the vehicle motor is operating normally. The comparison data for subsequent vehicle motor monitoring to determine whether it is in a normal state can be directly used as a reference to derive the operating status of the vehicle motor and prepare for monitoring, thereby greatly improving the efficiency of data judgment;

[0061] In one embodiment, the step of formulating a control instruction corresponding to the monitoring item, wherein the control instruction includes a power on / off instruction, a gear instruction, and a speed control instruction, and formulating a detection control plan according to the control instruction includes:

[0062] Acquisition project, obtains the control information change instruction of vehicle motor operation to obtain the control instruction;

[0063] Obtaining the order in which control instructions are executed during the operation of the vehicle motor, and arranging the control instructions according to the order to obtain a monitoring control scheme;

[0064] Set the time interval between control instructions according to the sequence, and automatically change the next control instruction according to the time interval and sequence to obtain a one-button monitoring control solution;

[0065] To further illustrate, the vehicle motor is monitored during the process of controlling the operation of the vehicle motor. First, the control information change instructions for the vehicle motor operation are obtained according to the project (the vehicle driving behavior to be simulated, and the performance data of the vehicle motor control under the driving behavior are monitored). For example, in the R gear, start accelerating backward, then brake to stop, then change to the D gear, start accelerating forward, and then brake to stop. This is a driving behavior (simulating parking in a garage), among which "R gear", "start accelerating backward", "brake to stop", "change to D gear", "accelerate forward" and "brake to stop" are control information change instructions and serve as control instructions, and the order of the above control information change instructions The sequence of execution during the operation of the vehicle motor is arranged in sequence. The preceding and following instruction lines of the control information change instruction are the detection control scheme, which can simulate the data of the vehicle motor control under the behavior control during the actual vehicle driving process. Among them, the behavior simulated during the actual vehicle driving process is the project. The instructions in the project are extracted to obtain the control instructions. The monitoring control scheme can be obtained and stored as a fixed monitoring scheme for subsequent use, which can greatly improve the monitoring efficiency of the operation data during the vehicle motor control process. It can be used with one button, and there is no need to manually click to change according to the instruction to be simulated. The operation is also more intelligent and simple.

[0066] In one embodiment, the step of formulating a verification monitoring plan based on the monitoring items includes:

[0067] Obtain multiple indicators in the one-key monitoring and control plan, and formulate multiple one-key monitoring and control plans as verification monitoring plans with a single indicator as a verification point;

[0068] It is further explained that when a one-button monitoring and control scheme is obtained, since any indicator in the process may be abnormal during the operation of the one-button monitoring and control scheme, an independent verification scheme is required for the indicators in the one-button monitoring and control scheme, and multiple one-button monitoring and control schemes are formulated. For example, in "R gear", "start acceleration and reverse", "brake stop", "change to D gear", "accelerate forward" and "brake stop", the controller temperature is abnormal during the brake stop in D gear. Therefore, the controller temperature indicator during the brake stop in D gear is used as a verification point, and multiple one-button monitoring and control schemes are formulated. For example, in D gear, start at a certain speed, then brake slowly, and check The controller temperature situation, in one, in D gear, start at other speeds, then emergency brake, check the controller temperature situation, these two are two one-button monitoring control schemes, which can monitor the controller temperature under multiple data during the brake stop process in D gear. Other indicators adopt the same method to formulate and store multiple verification monitoring schemes. When an indicator abnormal state occurs later, the verification monitoring scheme is started corresponding to the abnormal state of the indicator to verify whether the abnormal state of the indicator has always been abnormal or is caused by a specific value (behavior). The indicator status is better monitored, which greatly improves the verification efficiency of the indicator status. The verification monitoring scheme can be directly called, which is more practical.

[0069] In one embodiment, the step of obtaining current monitoring data of the vehicle motor based on a monitoring control scheme and treating the current monitoring data that exceeds a preset condition of normal data as abnormal data includes:

[0070] Monitor the vehicle motor indicators according to the one-button monitoring control solution to obtain current monitoring data, and search for normal data preset conditions based on the current monitoring data;

[0071] The current detection data that does not meet the preset conditions of normal data is obtained by comparison and regarded as abnormal data;

[0072] It is further explained that in the actual operation of the vehicle motor, the vehicle motor is controlled and operated through a one-button monitoring and control solution, and then the indicators during its operation are monitored. The corresponding normal data preset conditions are found according to the monitored values ​​of the indicators. The current monitoring data that does not meet the normal data preset conditions is obtained according to the normal data preset conditions, and then the current detection data is used as abnormal data. While monitoring the vehicle motor, the monitoring indicators of the vehicle motor control operation are compared with the normal data preset conditions. According to the current detection data that does not meet the normal data preset conditions and is used as abnormal data, the abnormal data can be quickly obtained, thereby improving the efficiency of determining the abnormal data, and can be used for subsequent processing of the abnormal data to determine the fault location;

[0073] In one embodiment, the steps of acquiring abnormal data and obtaining verification data according to the verification monitoring scheme, determining whether the verification data meets the normal data preset conditions, and treating the verification data that does not meet the normal data preset conditions as fault data include:

[0074] Obtain abnormal data and find the verification monitoring plan corresponding to the single indicator in the abnormal data;

[0075] Verify a single indicator in the abnormal data based on the verification monitoring plan to obtain verification data;

[0076] Obtaining abnormal data of a single indicator in abnormal data that does not meet the preset conditions of normal data as fault data;

[0077] Further explanation: abnormal data is obtained, and a single indicator in the abnormal data is monitored separately, and a verification monitoring plan corresponding to the single indicator is obtained. According to the verification monitoring plan, data verification is performed on the single indicator of the vehicle motor operation process. Verification data of the single indicator is obtained based on the verification monitoring plan, and the verification data is compared with the preset conditions of the normal data to obtain verification abnormal data that does not meet the preset conditions of the normal data. The abnormal data of a single indicator in the verification abnormal data is used as fault data. In this case, it can be basically determined that the abnormal data of the indicator is the fault data, and then the staff can infer possible problems based on the fault data, perform maintenance on the vehicle motor, and quickly understand the operating performance of the vehicle motor. There is no need for the staff to manually control step by step. Through one-click setting, the monitoring of the vehicle motor operating performance is automatically completed, and the abnormal data is obtained. After a one-time verification, it is determined whether the indicator is abnormal, thereby improving the monitoring efficiency of the vehicle motor performance.
