Detailed Description
The data acquisition device and method for the distribution box are used for improving the acquisition accuracy of current data and voltage data of the distribution box.
In order to make the objects, features and advantages of the present invention more comprehensible, the technical solutions in the embodiments of the present invention are described in detail below with reference to the accompanying drawings, and it is apparent that the embodiments described below are only some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1 to 2, the invention provides a data acquisition device of a distribution box, which comprises a handheld terminal 2 and non-contact current and voltage acquisition equipment 1, wherein the handheld terminal 2 comprises a controller 21, an image acquisition module 22 and a display module 23, and the image acquisition module 22 and the display module 23 are connected with the controller 21;
the image acquisition module 22 is used for acquiring an installation image containing the installation position of the non-contact current and voltage acquisition equipment 1 when the non-contact current and voltage acquisition equipment 1 is installed on equipment to be tested in the distribution box;
The controller 21 is configured to acquire an installation image and a pre-stored target image of the device to be tested, the target image being labeled with an optimal data acquisition position, determine a transformation relationship between the target image and the installation image by using a feature point matching algorithm, determine a distance between the optimal data acquisition position and an installation position of the non-contact current voltage acquisition device 1 according to the transformation relationship, and label the installation image with the optimal data acquisition position when the distance is not within a preset distance interval, and the display module 23 is configured to display the installation image labeled with the optimal data acquisition position.
The non-contact current and voltage acquisition device 1 is in communication connection with the handheld terminal 2 and is used for acquiring current data and voltage data in the distribution box. The non-contact current and voltage acquisition device 1 is a device capable of measuring current and voltage without directly contacting a conductor to be measured. The non-contact type current and voltage acquisition equipment 1 in the embodiment comprises a U-shaped current sensor and a U-shaped voltage sensor, and can measure voltage and current under the condition of not being in direct contact, so that the operation requirement of a distribution box with a narrow space can be well met, the problem that potential safety hazards such as electric shock exist due to the fact that a meter pen is required to be used for contacting a conductor to be measured when the voltage is measured in the prior measuring technology is avoided.
The optimal data acquisition position is used for indicating a position on the device to be tested, wherein accurate data acquisition can be performed. The feature point matching algorithm is an image processing method for determining correspondence between different images, and in one example, a feature point matching algorithm such as SIFT, SURF, ORB may be employed.
In actual use, after the non-contact current and voltage acquisition device 1 is installed on a device to be tested of a distribution box, the image acquisition module 22 of the handheld terminal 2 is used for acquiring an image of the installed non-contact current and voltage acquisition device 1, so as to obtain an installation image containing the installation position of the non-contact current and voltage acquisition device 1, the image acquisition module 22 transmits the installation image to the controller 21, the controller 21 receives the installation image, and the pre-stored image (namely, target image) of the device to be tested marked with the optimal data acquisition position is acquired. Because shooting angle deviation may exist between the target image and the installation image, in this embodiment, the controller 21 matches the installation image with the target image by adopting a feature point matching algorithm according to feature points of the target image and the installation image, determines a transformation relationship between the installation image and the target image according to a matching result, and determines a target position corresponding to an optimal data acquisition position in the installation image according to the transformation relationship, thereby realizing determination of the optimal data acquisition position of the device to be detected in the installation image, and reducing the condition of inaccurate image data caused by the shooting angle deviation.
After determining the target position, the controller 21 calculates the distance between the target position and the installation position as the distance between the optimal data acquisition position and the installation position, and judges whether the distance is within a preset distance interval, if yes, it is indicated that the non-contact current voltage acquisition device 1 is installed in place, accurate current data and voltage data acquisition can be performed, if no, it is indicated that the non-contact current voltage acquisition device 1 is not installed in place, and accurate current data and voltage data acquisition cannot be performed, therefore, by marking the optimal data acquisition position on the installation image, displaying the installation image marked with the optimal data acquisition position by adopting the display module 23, a worker can intuitively determine the installation situation of the non-contact current data and the voltage data acquisition device and the distance between the installation situation and the optimal data acquisition position, thereby providing a convenient prompt for the worker to adjust the installation position of the non-contact current voltage acquisition device 1 in a distribution box in space, so that the worker can more accurately determine the optimal data acquisition position, and perform installation adjustment of the non-contact current voltage acquisition device 1, and can intuitively improve the installation situation of the non-contact current voltage acquisition device 1 and the optimal data acquisition position.
In a specific embodiment, the optimal data acquisition location is the location of the conductor centerline of the device under test.
The position of the center line of the conductor is the position of the virtual straight line located at the geometric center of the conductor. The location of the conductor centerline may provide a reference for current distribution, a reference for positioning of the installation and layout of electrical equipment, and a reference for conductor magnetic field calculation. Therefore, the position of the center line of the conductor of the device to be tested is used as the optimal data acquisition position, so that the current data and the voltage data acquired by the non-contact current and voltage acquisition device 1 can be fed back to the real situation of the device to be tested more accurately, and the data acquisition precision of the non-contact current and voltage acquisition device 1 is improved.
In a specific embodiment, the controller 21 is specifically configured to obtain, in response to location information input by a user, a target image of a device under test associated with the location information.
In the actual use process, the staff uses the prompt of the display module 23 to input the location information of the device to be tested, the display module 23 transmits the location information to the controller 21, and the controller 21 obtains the target image of the corresponding device to be tested from the storage module 26 based on the location information of the device to be tested, thereby realizing accurate obtaining of the target image of the device to be tested.
It can be understood that in an actual working scenario, because of the numerous distribution boxes, the storage module 26 stores a large number of images of devices to be tested of each distribution box, and in this embodiment, by associating the location information with the target image in advance and storing the association relationship in the storage module 26, when the target image needs to be called, the target image of the corresponding device to be tested can be accurately called based on the location information.
In one example, by numbering the distribution box and the devices in the distribution box, and associating the device numbers, location information, and target images, more accurate target image retrieval may be achieved.

The signal processing includes filtering, amplifying, analog-to-digital conversion, and the like. After receiving the voltage data and the current data after the signal processing, the controller 21 transmits the voltage data and the current data to the display module 23 for display, so that a worker can intuitively know the voltage data and the current data of the device to be tested.
In a specific embodiment, the display module 23 may be provided with a touch function display module 23, and the staff member may perform voice or text input. If the hand-held terminal 2 has a voice function, a voice module is arranged in the hand-held terminal
In a specific embodiment, the handheld terminal 2 further comprises a temperature acquisition module 25;

The temperature acquisition module 25 may be a temperature sensor.
In this embodiment, the temperature collecting module 25 is configured to collect an ambient temperature of the device under test, and is configured to determine whether the ambient temperature is within a preset temperature threshold range, if yes, it indicates that the current temperature environment has less interference to the non-contact current-voltage collecting device 1, at this time, the controller 21 may output a start-up collecting signal to the non-contact current-voltage collecting device 1, so that the non-contact current-voltage collecting device 1 performs voltage data collection and/or current data collection, and then the signal processing module 24 receives the voltage data and the current data collected by the non-contact current-voltage collecting device 1, and after performing signal processing on the voltage data and/or the current data, outputs the processed voltage data and/or current data to the storage module 26 and the display module 23 for storage and display.
If the ambient temperature is not in the preset temperature threshold range, it is indicated that the current ambient temperature of the device to be tested may interfere with the data precision of the non-contact current-voltage acquisition device 1, at this time, the current ambient temperature is compared with the maximum value and the minimum value of the temperature threshold range respectively, a corresponding target temperature drift compensation model is determined according to the comparison result, the temperature compensation is performed on the non-contact voltage-current data by using the target temperature drift compensation model, the problem of inaccurate measurement value caused by temperature drift is avoided, and the precision of the acquired distribution box data is further improved.
In a specific embodiment, the controller 21 is specifically configured to obtain the first temperature drift compensation model after training as the target temperature drift compensation model when the temperature environment is less than the minimum value of the temperature threshold range.
It should be noted that, in this embodiment, the first temperature drift compensation model is pre-constructed and trained, so as to perform temperature compensation on the current data/voltage data collected by the non-contact current-voltage collection device 1 in a scenario that the environmental temperature value is smaller than the minimum value of the temperature threshold preset range. The number of the first temperature drift compensation models can be two, and the first temperature drift compensation models are used for respectively performing temperature compensation on the current data and the voltage data.
Taking current data as an example, the training step of the first temperature drift compensation model comprises the steps of firstly constructing an environment with the temperature smaller than the minimum value of a preset temperature range, collecting current data of equipment to be tested under the environment as a training sample, then constructing the environment within the preset temperature threshold range, collecting the current data of the equipment to be tested under the environment as a target sample, forming a plurality of groups of training samples and a plurality of groups of target samples into a data pair, inputting the training sample into an initial neural network model, outputting a prediction compensation value, calculating a loss value between the target sample and the prediction compensation value, optimizing the neural network model through the loss value, outputting the neural network model until the set minimum error is met by the neural network model, and taking the neural network model as the first temperature drift compensation model.

In a specific implementation, the temperature threshold range may be set according to a standard operating environment temperature of the contactless current-voltage collecting device 1.
In a specific embodiment, the handheld terminal 2 further comprises a communication module;
The controller 21 is connected to the communication module and connected to the server through the communication module, and is configured to upload the data in the storage module 26 to the server.
It should be noted that the communication module may be a wired communication or a wireless communication, such as WIFI communication. The communication module is used for transmitting the stored data to the server. The server may be a cloud server or a computer terminal.
In a specific embodiment, the current value may be measured by a U-shaped current sensor, or the voltage value may be measured by a U-shaped voltage sensor. The present embodiment is not particularly limited in its measurement sequence.

In a specific embodiment, the handheld terminal 2 further comprises a voice module for providing voice functionality. For example, a worker may make voice input using a voice module.
In a specific embodiment, the storage module 26 is configured to store text entered by a worker, captured images, data processed by the signal processing module 24, matched image data, and the like, and provide data support for subsequent analysis.
In a specific embodiment, the image acquisition module 22 may be further configured to acquire face information of a user, and the controller 21 may be configured to perform face recognition on the face information and output a recognition result.
In one application example, the workflow of the present apparatus may be as follows:
After the worker arrives at the device to be tested, he enters the location on the display module 23 of the handheld terminal 2. The display module 23 sends the location information to the controller 21. The controller 21 retrieves the information of the staff member of the device to be tested according to the received location information, so as to display the information on the display module 23 and prompt the staff member to perform the identification operation. After the operator clicks the option of determining the identification on the display module 23, the controller 21 takes a facial photograph of the operator through the camera, the camera sends the taken facial photograph to the controller 21, the controller 21 checks the facial photograph, and after the face recognition passes, characters such as "pass" type characters are displayed on the display module 23 to prompt the operator to measure the current and the voltage.
And then, the staff installs the U-shaped current sensor and the U-shaped voltage sensor on the equipment to be tested. Taking the U-shaped current sensor as an example, since the inaccuracy of the installation positions of the U-shaped current sensor and the U-shaped voltage sensor easily results in inaccuracy of the measured current and voltage, after the U-shaped current sensor is installed on the device under test, the controller 21 displays a prompt message on the display module 23, such as "take installation condition with camera", or "take a photograph right in front of the U-shaped current sensor". Thereafter, the controller 21 acquires a photograph of the apparatus taken by the camera, and acquires a target image of the apparatus stored in advance according to the location information. There may be an angular deviation of the image photographed by the worker from the pre-stored image. And according to the characteristic points (such as corner points, intersection points and edge points) in the two images, matching the two images by using a characteristic point matching algorithm (such as SIFT, SURF, ORB and the like) to determine the transformation relationship between the two images. The target position of the center line position in the photographed image (i.e., the installation image) is determined according to the transformation relationship, and then the controller 21 determines whether the distance between the U-shaped current sensor and the target position is within a preset interval, and if not, the target position in the photographed image is displayed on the display module 23 to instruct the worker to reinstall the sensor. If yes, the controller 21 collects the temperature of the environment where the device under test is located (i.e. the ambient temperature) through the temperature collection module 25. When the ambient temperature is in the preset temperature range, the controller 21 controls the U-shaped current sensor to collect the current value, the signal processing module 24 carries out corresponding signal processing on the collected current value, the processed current value is stored in the storage module 26, and finally the processed current value and the voltage value are displayed on the display module 23.
When the ambient temperature is not within the preset temperature threshold range, it indicates that the ambient temperature does not conform to the working environment of the U-shaped current sensor, and there is temperature drift, so that the corresponding temperature drift compensation model is determined according to the ambient temperature, and the controller 21 performs temperature compensation calculation on the collected current value of the U-shaped current sensor by using the temperature drift compensation model, so that the condition that the measured value is inaccurate due to temperature drift is avoided, and the data precision is improved. The signal processing module 24 processes the compensated current value accordingly, stores the processed current value in the storage module 26, and displays the processed current value on the display module 23 together with the voltage value.
According to the invention, the controller obtains the installation image and the pre-stored target image of the device to be tested, adopts the characteristic point matching algorithm to determine the transformation relation between the target image and the installation image, determines the distance between the optimal data acquisition position and the installation position of the non-contact current and voltage acquisition device according to the transformation relation, marks the optimal data acquisition position on the installation image when the distance is not in the preset distance interval, and realizes the judgment of the accuracy of the installation position of the U-shaped voltage/current sensor, thereby providing technical support for accurate installation, ensuring the accuracy of voltage and current measurement and avoiding the situation that the measurement of the voltage and the current is inaccurate due to the deviation of the installation of the U-shaped voltage and current sensor. And after the position is determined to be installed without errors, the environment temperature is further measured, and the measured value is subjected to temperature compensation, so that the problem of inaccurate measured value caused by temperature drift is avoided. Therefore, the device provided by the invention firstly judges and adjusts the installation position of the U-shaped voltage/current sensor, and further judges the environment where the U-shaped voltage/current sensor is located, so that the influence of the installation position and the temperature on the measurement result of the U-shaped voltage/current sensor is avoided, the accuracy of the measurement result of the U-shaped voltage/current sensor is improved, and the acquisition accuracy of the distribution box data is improved as a whole.
