The following describes a pair of failure detection devices in detail by way of example.
Example one
As shown in fig. 1, a fault detection device provided in the first embodiment of the present application includes: an information acquisition part 11, a communication part 12, and a control part 13; the information acquisition part 11 is connected to the communication part 12, and the communication part 12 is connected to the control part 13.
In a specific implementation, the information collecting component 11 may collect the operation state data of the fault detection device in real time, or may collect the operation state data periodically, for example, it may be set to collect the operation state data once at twelve o 'clock in the middle of the night every day, and collect the operation state data once at twelve o' clock in the middle of the noon every day.
The operation state data of the failure detection apparatus acquired by the information acquisition section 11 includes operation data of each functional section of the failure detection apparatus. Wherein the functional components of the fault detection device comprise at least one of a power supply of the fault detection device, a motor of the fault detection device, a driver of the fault detection device, a torque sensor of the fault detection device. It should be noted that the information collection component may be a functional component itself, that is, the functional component reports its own operation state data to the communication component.
The information collection part 11 may collect its own status data. For example, for a power supply of the fault detection device, the power supply may collect its own voltage, temperature, electric quantity, etc.; for a motor of the fault detection equipment, the motor can acquire the temperature, the rotating speed and the like of the motor; for the driver of the failure detection device, the driver may collect its own communication function state, temperature, and the like.
In addition, the information acquisition part 11 may further include a torque sensor for acquiring a stepping torque of the fault detection device and transmitting the stepping torque to the control part in a voltage manner.
The operation state data of the fault detection apparatus collected by the information collection part 11 also includes fault data of each functional part of the fault detection apparatus. In a specific implementation, the information collecting part 11 may also determine the fault data of each functional unit according to the status data of each functional unit while collecting the status data of each functional unit. For example, if the power supply of the fault detection device fails due to an excessive temperature caused by poor quality, the power supply may determine that the fault data of the power supply is the fault data of the power supply with the temperature exceeding the first high temperature threshold.
The information collecting part 11 may determine different fault data for different faulty components. For a power supply of the fault detection equipment, fault data of overvoltage output, fault data of power supply short circuit, fault data of power supply temperature exceeding a first high-temperature threshold value and fault data of power supply temperature lower than a low-temperature threshold value can be determined according to collected running state data corresponding to the power supply; for a torque sensor of the fault detection equipment, fault data of short circuit of the torque sensor and fault data of output voltage of the torque sensor exceeding a preset voltage range can be determined according to running state data acquired by the torque sensor; for a driver of the fault detection equipment, fault data output by over-current of the driver, fault data of short circuit of the driver, fault data of temperature of the driver exceeding a second high-temperature threshold value and fault data of driving speed of the driver exceeding a preset vehicle speed range can be determined according to collected running state data corresponding to the driver; for the motor of the fault detection device, fault data that the temperature of the motor exceeds a third high-temperature threshold value can be determined according to the collected running state data corresponding to the motor.
The information collection part 11 transmits the collected above-described operation state data to the communication part 12, and the communication part 12 transmits the received operation state data to the control part 13.
The communication component 12 may be a wired communication component, that is, the information acquisition component 11 and the control component 13 are electrically connected to the wired communication component; wireless communication parts, namely the information acquisition part 11 and the control part 13, can be in communication connection with the wired communication part. In the implementation, the setting can be performed according to different requirements, and this is not specifically limited in the embodiments of the present application.
In a specific implementation, after the control part 13 receives the operation state data sent by the communication part 12, the control part 13 may classify the operation state data according to a preset classification rule. The control unit 13 may be an integrated circuit chip, a central processing unit with data processing capability.
Here, the classification rule may be to classify the operation state data according to the functional component to which the operation state data belongs, or may be to classify the operation state data according to the data attribute, or may classify the operation state data according to another classification rule, which is not specifically limited in this embodiment of the present application.
Next, two ways of classifying the operation state data according to the functional component to which the motion state data belongs and classifying the operation state data according to the data attribute, and a method for the control component 13 to further determine the fault evaluation information of the fault detection device after classification according to the two classification rules are respectively explained.
The first method comprises the following steps: the operating state data are classified according to the functional component to which the operating state data belong.
Specifically, when classifying the received operation state data according to the functional component to which the motion state data belongs, the control component 13 may use the voltage of the power supply, the temperature of the power supply, the electric quantity of the power supply, the fault data of overvoltage output, the fault data of power supply short circuit, the fault data of power supply temperature exceeding a first high temperature threshold, the fault data of power supply temperature lower than a low temperature threshold, and the like as the power supply class operation state data; taking the temperature and the rotating speed of the motor, fault data of the motor with the temperature exceeding a third high-temperature threshold value and the like as motor operation state data; taking the communication function state and temperature of the driver, fault data output by overcurrent of the driver, fault data of short circuit of the driver, fault data of temperature of the driver exceeding a second high-temperature threshold, fault data of driving speed of the driver exceeding a preset speed range and the like as driver running state data; and taking the voltage and the current of the torque sensor, the fault data of the short circuit of the torque sensor, the fault data of the output voltage of the torque sensor exceeding a preset voltage range and the like as the operation state data of the torque sensor and the like.
After the control unit 13 classifies the operation state data according to the functional unit to which the motion state data belongs, each type of operation state data includes at least one operation state data. The control unit 13 may analyze each operation state data in each type of operation state data to determine fault evaluation information corresponding to each type of operation state data, and summarize and analyze the fault evaluation information corresponding to each type of operation state data to determine fault evaluation information of the fault detection device.
In a specific implementation, the operation state data corresponding to each functional component may be analyzed according to the classification rule to determine the fault evaluation information of the functional component. For example, after analyzing each operation state data in the power supply operation state data, the fault evaluation information corresponding to the power supply operation state data, that is, the fault evaluation information corresponding to the power supply, may be determined; after each piece of operation state data in the driver class operation state data is analyzed, fault evaluation information corresponding to the driver class operation state data, that is, fault evaluation information corresponding to the driver, and the like can be determined.
After determining the fault evaluation information of each functional component in the fault detection device, the fault evaluation information corresponding to each functional component may be summarized and analyzed, so as to determine the fault evaluation information of the fault detection device.
The fault evaluation information of each functional component may include a fault evaluation score corresponding to the functional component. Specifically, each operating state data corresponding to the functional component and a weight value corresponding to each operating state data are weighted to obtain a fault evaluation score of the functional component. Further, the fault evaluation scores of all the functional components are collected and analyzed, and the fault evaluation score of the fault detection equipment is determined. Specifically, the failure evaluation score of each functional component and the weight value corresponding to each functional component may be weighted to obtain the failure evaluation score of the failure detection device, and the failure evaluation score is used as the failure evaluation information corresponding to the failure detection device. Wherein the failure evaluation score is used to indicate the degree of abnormality of the corresponding functional component or the failure detection apparatus.
The failure evaluation information of each functional component may be a current state evaluation level corresponding to the functional component. Specifically, the reference evaluation score of the functional component is determined according to each operating state data corresponding to the functional component and a first preset calculation rule. And determining a current state evaluation grade corresponding to the functional component according to a mapping relation between the pre-established evaluation score and the state evaluation grade based on the reference evaluation score, wherein the state evaluation grade is used for indicating the use state of the corresponding functional component or the fault detection equipment. The state evaluation level may include to-be-repaired, normal, and excellent, and the state evaluation level may be set according to actual requirements, which is not specifically limited in the embodiments of the present application.
And the second method comprises the following steps: and classifying the running state data according to the data attributes.
When the operation state data are classified according to the data attributes, the voltage of the power supply, the voltage of the torque sensor, the fault data output by the voltage of the power supply, the fault data of the output voltage of the torque sensor exceeding a preset voltage range and the like can be used as voltage operation state data; collecting current of a torque sensor, output current of a power supply, current of a motor and the like as current type running state data; taking the temperature of a power supply, the temperature of a motor, the temperature of a driver, fault data of which the temperature of the power supply exceeds a first high-temperature threshold, fault data of which the temperature of the driver exceeds a second high-temperature threshold, fault data of which the temperature of the motor exceeds a third high-temperature threshold and the like as temperature-type running state data; the short-circuit type operating state data includes, for example, data on a power supply short circuit fault, data on a torque sensor short circuit fault, and data on a driver overcurrent output fault.
After the control section 13 classifies the operation state data according to the data attributes, each type of operation state data includes at least one operation state data. The control unit 13 may analyze each operation state data in each type of operation state data to determine fault evaluation information corresponding to each type of operation state data, and summarize and analyze the fault evaluation information corresponding to each type of operation state data to determine fault evaluation information of the fault detection device.
In a specific implementation, if the operation state data is classified according to the data attribute, the voltage state, the current state, the temperature state, and the like of the fault detection device can be analyzed respectively. For example, after each operation state data in the voltage operation state data is analyzed, the fault evaluation information corresponding to the voltage operation state data can be determined; after each piece of operation state data in the current operation state data is analyzed, fault evaluation information and the like corresponding to the current operation state data can be determined.
After determining the fault evaluation information of various types of operation state data in the fault detection device, the fault evaluation information corresponding to the voltage type operation state data, the fault evaluation information corresponding to the current type operation state data, the fault evaluation information corresponding to the temperature type operation state data, and the fault evaluation information corresponding to the short circuit type operation state data may be summarized and analyzed, so as to determine the fault evaluation information of the fault detection device.
The fault evaluation information may be fault evaluation scores respectively corresponding to the voltage, the current, the temperature and the like of the whole fault detection device. Specifically, each running state data in various running state data and a weight value corresponding to each running state data are weighted and calculated, so that a fault evaluation score is obtained. Further, the fault evaluation scores of the various types of running state data are collected and analyzed, and the fault evaluation score of the fault detection device is determined, wherein the fault evaluation score of the fault detection device can be obtained by performing weighted calculation on the fault evaluation scores of the various types of running state data and the weight value corresponding to the various types of running state data, and the fault evaluation score is fault evaluation information corresponding to the fault detection device. The failure evaluation information is used to indicate the state of each attribute in the failure detection device or the degree of abnormality of the failure detection device.
The fault evaluation information corresponding to each type of operation state data in each fault detection device may be a current state evaluation level corresponding to each type of operation state data in the fault detection device. Specifically, a reference evaluation score of each type of running state data in the fault detection device is determined according to each running state data in the running state data and a preset calculation rule, and a current state evaluation grade corresponding to the type of running state data is determined according to a mapping relation between a pre-established evaluation score and the state evaluation grade on the basis of the reference evaluation score, wherein the state evaluation grade is used for representing the state of a corresponding attribute or the working state of the fault detection device. The state evaluation level may include poor, general and good, and the state evaluation level may be set according to actual requirements, which is not specifically limited in the embodiments of the present application.
The control unit 13 can determine the fault evaluation information corresponding to each type of operation state data and the fault evaluation information of the fault detection device through the two classification manners, and send the fault evaluation information corresponding to each type of operation state data and the fault evaluation information of the fault detection device to the communication unit 12, so that the communication unit 12 reports each operation state data, the fault evaluation information corresponding to each type of operation state data and the fault evaluation information of the fault detection device to the server, so that the server can perform backup.
As shown in fig. 1, the failure detection device provided in the first embodiment of the present application further includes a memory 14 connected to the control unit 13; the memory is used for storing the operation state data, the fault evaluation information corresponding to each type of operation state data and the fault evaluation information of the fault detection equipment, and avoiding the problem that the operation state data, the fault evaluation information corresponding to each type of operation state data and the fault evaluation information of the fault detection equipment cannot be reported to the server successfully and backup fails due to the fact that the communication component 12 breaks down.
When the communication component 12 does not report the operation state data, the fault evaluation information corresponding to each type of operation state data, and the fault evaluation information of the fault detection device to the server successfully, the control component 13 may send the operation state data, the fault evaluation information corresponding to each type of operation state data, and the fault evaluation information of the fault detection device stored in the memory 14 to the communication component 12 again after a preset time period, so that the communication component 12 reports the operation state data, the fault evaluation information corresponding to each type of operation state data, and the fault evaluation information of the fault detection device to the server.
In the first embodiment of the present application, the information acquisition component 11 sends the acquired operation state data of each functional component of the fault detection device to the communication component 12; the communication section 12 transmits the received operation state data to the control section 13; the control part 13 classifies the operation state data, and respectively determines the fault evaluation information corresponding to each type of operation state data according to each operation state data in each type of operation state data; determining fault evaluation information of the fault detection equipment according to the fault evaluation information corresponding to each type of running state data; and the fault evaluation information corresponding to each type of running state data and the fault evaluation information of the fault detection device are reported to the server through the communication part 12. By adopting the fault detection equipment provided by the embodiment of the application, the fault evaluation information can be automatically determined and reported to the server, and the fault detection equipment is favorable for timely troubleshooting by maintenance personnel.
In a specific implementation, the control component 13 may further determine a failed functional component and a failure type of the failure detection device based on each operating state data of each type of operating state data, and determine a maintenance strategy according to the determined failed functional component and the failure type.
For example, the power supply operation state data includes fault data that the power supply temperature of the fault detection device is lower than a low-temperature threshold, so that it can be determined that the power supply of the fault detection device has a fault, and the fault type is that the temperature is too low; the short-circuit operation state data comprises fault data of driver short circuit, so that the driver of the fault detection equipment can be determined to be in fault, and the fault type is short circuit and the like.
The control unit 13 may search, based on the determined functional component and the determined fault type, a maintenance strategy corresponding to the functional component and the fault type that have a fault currently in advance among the maintenance strategies established for the functional components and the fault types, so that a maintenance worker can perform troubleshooting in time and efficiently.
In a specific implementation, the control unit 13 may upload the currently failed functional unit and the maintenance strategy corresponding to the failure type to the server, so as to facilitate the server to perform backup. The server can also select maintenance personnel matched with the maintenance strategy from a pre-stored maintenance personnel list according to the functional component with the current fault and the maintenance strategy corresponding to the fault type, generate a maintenance work order and send the maintenance work order to the equipment terminal corresponding to the maintenance personnel.
As shown in fig. 1, the failure detection apparatus provided in the first embodiment of the present application further includes a display unit 15 connected to the control unit 13, and the display unit 15 is configured to receive and display the failed functional unit, the failure type, and the maintenance strategy received from the control unit 13.
