For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, including but not limited to combinations of embodiments, which are within the scope of the application, can be made by one of ordinary skill in the art without inventive effort based on the embodiments of the application.
The terms "first," "second," "third," "fourth" and the like in the description and in the claims and in the above drawings, if any, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the application described herein may be implemented, for example, in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The application is characterized in that:
when the hall sensor is used for detecting real-time motion information of an object (such as a motor, a flywheel, a cam shaft, a crank shaft, a gear and the like) doing circular motion, the data accuracy of the hall sensor is very high. For research and maintenance personnel, it is necessary to know not only whether the hall sensor has a fault, but also the type of the fault. Therefore, the application is provided with at least one monitor for each Hall sensor, and the Hall sensors can be monitored by utilizing the historical motion data at similar moments in consideration of the characteristic of periodicity of circular motion, thereby realizing the further identification of the type of the fault on the basis of the fault identification.
The fault display method of the Hall sensor provided by the application is described in detail below.
Fig. 1 is a schematic flow chart of a hall sensor fault display method according to an embodiment of the present application. As shown in fig. 1, the method is applied to a fault monitor, optionally integrated in a hall sensor or controller. The method comprises the following specific steps:
s101, acquiring real-time detection data of a Hall sensor and historical motion data of a detected object in circular motion.
In this step, the hall sensor is used for detecting real-time motion information when the object to be measured performs circular motion in real time. The historical motion data includes: in the period of N (N is more than or equal to 1) circular motions, at least one of the speed, the acceleration, the angular speed and the angular acceleration of the measured object is measured. It should be noted that the historical motion data may be obtained from the control data output by the controller, may be read from the memory, or may be read from the historical data record of the database.
In one possible design, the historical motion data may also be motion data of the object under similar operating conditions.
In this embodiment, the object to be measured includes: motors, flywheels, cams, camshafts, crankshafts, gears, and the like.
S102, determining the target moment of the Hall sensor for outputting the target detection signal according to the historical motion data by using a preset circular motion model.
In this step, since the working state of the object to be measured may be continuously changed, it is necessary to adjust the working state according to different operation conditions in the preset circular motion model.
In one possible design, the historical motion data includes: the specific implementation manner of the step includes:
and determining the target moment according to the first angular velocity, the first angular acceleration, the first moment and the target rotation angle by using a preset circular motion model. One possible implementation of the preset circular motion model is shown in formula (1):
wherein t is target For the target moment omega 1 At a first angular velocity ρ ω For the angular velocity correction factor, a 1 For a first angular acceleration ρ a For the angular acceleration correction factor, t 1 For the first moment, θ target Is the target rotation angle.
Solving the equation shown in the formula (1) can obtain the target time. It is to be noted that the angular velocity correction coefficient ρ ω And an angular acceleration correction coefficient ρ a The angular acceleration correction coefficient ρ is different when the object is in different operation states, e.g. during uniform acceleration or uniform deceleration movement a When the device is in non-uniform acceleration or non-uniform deceleration, the specific value of the device can be calibrated in advance, and then the monitor can identify different running states according to the control instruction output by the controller.
It should also be noted that, in order to ensure accuracy of the target timeFirst time t 1 And target time t target And the interval is not more than 5-8 circular motion periods as much as possible.
S103, judging whether the Hall sensor has faults or not according to the real-time detection data and the target moment by using a fault detection model.
In this step, if it is determined that the hall sensor has failed, S104 is performed.
Specifically, whether the real-time detection data has a target detection signal at the target time or in a target interval corresponding to the target time is judged, if so, the Hall sensor is proved to be normal, otherwise, the Hall sensor is proved to have faults.
Alternatively, the upper limit value of the target interval may be obtained by adding the first deviation threshold to the target time, and the lower limit value may be obtained by subtracting the second deviation threshold from the target time. In particular, the first deviation threshold may be equal to the second deviation threshold.
For example, a timer may be set in the monitor, the target detection signal may be a rising edge signal and/or a falling edge signal of the digital signal, where the rising edge is exemplified by a rising edge, and the target time corresponding to the rising edge is 3.5S, and when the timer counts to 3.5S, whether the rising edge signal occurs in the real-time monitoring signal or whether the rising edge signal occurs in the interval range of 3.3-3.6 is detected, if the rising edge signal occurs, the hall sensor is proved to have no fault, otherwise, the hall sensor is proved to have the fault.
Further, considering that the hall sensor can have the phenomenon of advancing or delaying the target detection signal due to the installation position or sensitivity conversion, or the situation that the number of times of the target detection signal is too high or too low due to false touch and temperature drift, the application performs the following treatment.
In one possible design, the specific implementation manner of this step includes:
s1031, determining the occurrence times of target detection signals in the real-time detection data in at least one fault detection period corresponding to the target time.
In this step, for example, one failure detection period includes 3 circular movement periods, and when the target detection signal is a rising edge signal, each circular movement period should occur 1 time, and then should occur 3 times in total in one failure detection period, if the hall sensor fails, the rising edge signal detected by the hall sensor may increase or decrease. Therefore, by setting a counter in the fault monitor, the counter is automatically incremented by 1 every time a target detection signal appears in the real-time monitoring data, so that the number of occurrences in the fault monitoring period can be calculated.
S1032, judging whether the occurrence number meets the preset fault judgment condition.
In the step, if yes, determining that the Hall sensor has faults.
The preset fault determination bar includes: and determining whether the occurrence times are equal to the preset times or not, and if not, determining that the Hall sensor fails.
S104, determining the fault type according to the real-time detection data and the target moment by using the fault type identification model.
In this step, at least the following three cases are included:
(1) When the occurrence number of the target detection signals is larger than a preset frequency threshold, determining that the fault type is a first fault type, wherein the first fault type is used for representing that the sensitivity of the Hall sensor is too high or the installation position is incorrect or an interference source exists. For example, when the rising edge signal and/or the falling edge signal occur too many times, the digital hall sensor may be installed too close to the trigger magnetic field, or the sensitivity of the sensor may be too high due to aging or operating temperature.
(2) And when the occurrence number of the target detection signals is smaller than a preset frequency threshold value and larger than zero, determining that the fault type is a second fault type, wherein the second fault type is used for representing that the sensitivity of the Hall sensor is too low or the installation position is incorrect. For example, rising edge signal and +.
Or the number of falling edge signal occurrences is missing, it may be that the digital hall sensor mounting position is too far away from the trigger magnetic field, or the sensitivity of the sensor is reduced due to aging or operating temperature.
(3) And when the occurrence number of the target detection signal is zero, determining that the fault type is a third fault type, wherein the second fault type is used for representing the open circuit or the short circuit of the Hall sensor.
S105, outputting and displaying early warning information according to the fault type and a preset display rule.
In this embodiment, not only is whether the hall sensor has a fault detected, but also finer fault type information is provided for research, development and maintenance personnel, so that the research, development and maintenance personnel can quickly locate the problem, and a solution is provided efficiently.
Specifically, the display mode of the early warning information can be determined according to the fault type, and then the early warning information is displayed on a display screen or a display area which is positioned in the same direction as the position of the detected object according to the display mode.
For example, taking a measured object as a motor as an example, in order to control a brushless motor, a motor controller needs hall sensors to input position information of motor rotation, and in the field of new energy automobiles, in an application scene of driving a hub motor or a wheel hub motor, 2n (n is greater than or equal to 1) motors can be arranged on the automobile, and each motor at least comprises 3 hall sensors.
In order to enable a research staff or maintenance staff or a driver to quickly and conveniently locate the Hall sensor with faults, fault indication lamps or fault display screens can be respectively arranged at the left front, the left rear, the right front and the right rear of the vehicle, and of course, different areas can be divided on a driving instrument panel or a central control screen to represent the Hall sensors on different motors. In this way, the hall sensor with faults can be conveniently found, and different faults can be indicated through different display modes, for example, the first type of faults are flash, the second type of faults are flash, the third type of faults are normally on, or the different types of faults are represented by different screens, for example, the third type of faults are the most serious, and the faults of other types can be displayed on a central control screen.
The embodiment provides a fault display method of a Hall sensor, which is characterized in that a test request sent to a detection platform when a plurality of monitoring objects meet is obtained, and each monitoring object is loaded with at least one digital Hall sensor and/or at least one test device; determining an authority configuration instruction according to a preset authority allocation rule and each test request, and sending the authority configuration instruction to each monitoring object, wherein the authority configuration instruction is used for designating the monitoring object as a test leading object or a tested object and instructing the test leading object to start one or more test devices to test at least one digital Hall sensor on the tested object; receiving monitoring data sent by a tested object, analyzing the monitoring data by using a preset monitoring model to obtain an analysis result, wherein the monitoring data comprises: after receiving the permission configuration instruction, the tested object outputs digital signals from one or more digital Hall sensors on the tested object; judging whether each digital Hall sensor on the measured object needs to be calibrated according to the analysis result; if yes, a calibration instruction is sent to the tested object, and the technical problem of how to monitor the digital Hall sensor is solved. The monitoring is carried out through the mutual test between the monitoring objects, the real-time requirements on the monitoring objects and the monitoring platform are reduced, and the effectiveness and the application range of the monitoring method are improved.
