[0014] A method for using a data acquisition device for a distribution network detection device without a communication function, based on the above-mentioned data acquisition device for a distribution network detection device without a communication function, comprises the following steps:

[0015] Step 1: Check the appearance of the device to ensure that the chassis, display, signal transmitter, data connector, infrared sensor, ultrasonic sensor, and storage components are not damaged, the connections are firm, all sensors function normally, and the signal transmitter can communicate normally;

[0016] Step 2: Select a suitable data connection line from the storage component according to the data interface type of the power distribution network detection equipment to be detected;

Connect one end of the selected data connection line to the data connector of the device, and connect the other end to the corresponding interface of the distribution network detection equipment to ensure good electrical connectivity and tight connection without looseness to prevent signal transmission interruption or interference, and then start the device for data collection.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The present invention provides a storage component. When the device is not in use or after use, the data connection line can be placed in a storage box in the storage component for storage, the flip cover is opened, and the data connection line is fixed by a fixing component. Then, the rotating shaft is rotated by a limiting component. At this time, the rotating shaft drives the limiting plate to rotate. When the limiting plate rotates, it can drive the fixing component to move together. In this way, the position of the fixing component in the storage box can be adjusted so that the fixing component can fix different data connection lines, thereby expanding the application range of the device.

[0020] 2. The present invention clamps one end of the data connection line in the groove on the surface of the sliding clamping block by setting a fixing component, and then clamps the other end of the data connection line in the groove on the surface of the limiting clamping block. During this process, the sliding clamping block also slides along the surface of the hollow rod, forcing the return spring to be compressed. At this time, under the elastic force of the return spring, the sliding clamping block and the limiting clamping block can tighten the data connection line to avoid disordered interweaving of multiple data connection lines, so that each data connection line remains independent and regularly arranged, which is convenient for quickly identifying and taking the required data connection line.

[0021] 3. The present invention sets an adjusting screw. When the adjusting screw is rotated, the limit clamping block can slide along the surface of the hollow rod. When the plug-in connector of the data connection line is large, the initial position of the limit clamping block can be adjusted by rotating the adjusting screw, thereby reserving sufficient placement space for the plug-in connector at the tail end of the data connection line, thereby enhancing the compatibility of the storage component.

[0022] 4. The present invention sets a winding rack. When the length of the data connection line is greater than the distance between the limit clamping block and the sliding clamping block, one end of the data connection line can be clamped on the surface of the sliding clamping block, and then the line body of the data connection line can be wound on the surface of the winding rack, and then the other end of the data connection line is fixed to the limit clamping block, so as to avoid the random stacking and interlacing of excess line length in the storage box, ensure the orderly storage environment, and improve the space utilization.

[0023] 5. The present invention sets a limit component, and six evenly distributed arc grooves are opened on the surface of the limit block. When the limit block is rotated, the limit block is accurately matched with the groove under the support of the elastic force of the compression spring. The compression spring ensures that the limit block is tightly against the surface of the limit block by virtue of constant elastic force, maintaining a stable contact state, so that the rotation step of the shaft is locked at sixty degrees, ensuring the accurate positioning of the fixed component and preventing it from being displaced due to accidental rotation of the shaft during the operation of fixing the data connection line.

[0024] 6. The present invention sets a limit screw. When the limit screw is rotated, the sliding block can slide in the fixed shell. When the sliding block approaches the limit block, the initial compression of the compression spring becomes larger, which can increase the contact pressure of the limit block on the limit block groove, enhance the stability of the rotation positioning of the shaft, ensure its sixty-degree rotation step is constant and accurate, and eliminate rotation misalignment caused by mechanical clearance, vibration or accidental collision.

[0025] 7. The present invention is developed based on the fully digital controller and the latest technology of the Internet of Things. With this device as a bridge, it can open up the efficient data collection of different distribution network instruments, internal and external network interaction, physical ID association and other contents. At the same time, as a supporting platform for miniaturized live detection instruments, the device supports infrared, ultrasonic and other miniaturized live detection instruments to interact with mobile terminals, which can realize convenient and efficient operations of basic teams. The device can improve the operation guarantee capability of the distribution network and reduce the operation and maintenance costs, effectively ensuring the strong operation of the city and county networks.

At this time, under the elastic force of the return spring 554, the sliding clamping block 55 3 and the limit clamping block 552 can tighten the data connection line 6 to avoid disorderly interweaving of multiple data connection lines 6, so that each data connection line 6 can be kept independent and neatly arranged, which is convenient for quickly identifying and taking the required data connection line 6. When the adjusting screw 555 is rotated, the limit clamping block 552 can slide along the surface of the hollow rod 551. When the plug-in connector of the data connection line 6 is large, the initial position of the limit clamping block 552 can be adjusted by rotating the adjusting screw 555 to reserve sufficient placement space for the plug-in connector at the tail end of the data connection line 6, thereby enhancing the compatibility of the storage component 5; when the length of the data connection line 6 is greater than the limit clamping block When the distance between 552 and the sliding clamping block 553 is small, after one end of the data connection cable 6 is clamped on the surface of the sliding clamping block 553, the line body of the data connection cable 6 can be wound on the surface of the winding frame 556, and then the other end of the data connection cable 6 is fixed to the limit clamping block 552, so as to avoid the random stacking and interlacing of excess line length in the storage box 51, ensure the orderly storage environment and improve the space utilization rate.

A compression spring 566 is fixedly connected, and the bottom end of the compression spring 566 is fixedly connected to a limit block 567. The outer side of the limit block 567 contacts the outer side of the limit block 562. The outer side of the sliding block 565 is slidably connected to the inner wall of the fixed shell 561. The inner wall of the fixed shell 561 is slidably connected to the outer wall of the limit block 567. When the rotating shaft 53 is rotated by the limit component 56, the knob 563 is rotated so that the knob 563 drives the limit block 562 inside the fixed shell 561 to rotate. At this time, the limit The other side of the block 562 drives the rotating shaft 53 to rotate. The surface of the limit block 562 is provided with six evenly distributed arc grooves. When the limit block 562 is rotated, the limit block 567 is precisely matched with the groove under the elastic support of the compression spring 566.

The physical structure includes but is not limited to RS-232, 485, CAN, USB, GPIB and customized interfaces of detection equipment.

[0041] When fixing, one end of the data connection line 6 is clamped in the groove on the surface of the sliding clamping block 553, and then the other end of the data connection line 6 is clamped in the groove on the surface of the limiting clamping block 552. During this process, the sliding clamping block 553 also slides along the surface of the hollow rod 551, forcing the return spring 554 to be compressed.

[0042] When the adjusting screw 555 is rotated, the limit clamping block 552 can slide along the surface of the hollow rod 551. When the plug-in connector of the data connection line 6 is large, the initial position of the limit clamping block 552 can be adjusted by rotating the adjusting screw 555 to reserve sufficient placement space for the plug-in connector at the tail end of the data connection line 6, thereby enhancing the compatibility of the storage component 5.

[0044] When the rotating shaft 53 is rotated by the limiting component 56, the knob 563 is turned so that the knob 563 drives the limiting block 562 on the inner side of the fixed shell 561 to rotate. At this time, the other side of the limiting block 562 drives the rotating shaft 53 to rotate. Six evenly distributed arc grooves are provided on the surface of the limiting block 562. When the limiting block 562 is rotated, the limiting block 567 precisely fits with the groove under the elastic support of the compression spring 566. The compression spring 566 ensures that the limiting block 567 is tightly against the surface of the limiting block 562 by means of constant elastic force, maintaining a stable contact state, so that the rotation step of the rotating shaft 53 is locked at sixty degrees, ensuring the accurate positioning of the fixing component 55 and preventing its position displacement caused by accidental rotation of the rotating shaft 53 during the operation of fixing the data connection line 6.

When the sliding block 565 approaches the limit block 567, the initial compression of the compression spring 566 becomes larger, which can increase the contact pressure of the limit block 567 on the groove of the limit block 562, enhance the stability of the rotation positioning of the shaft 53, ensure its sixty-degree rotation step is constant and accurate, and eliminate rotation inaccuracy caused by mechanical clearance, vibration or accidental collision.

After three confirmations, the display screen displays the words "matching successful, start data transmission", and the FPGA logic unit takes advantage of its fast computing speed, uses the clock signal to quickly lock the phase, and transmits the frequency information to the CPU through a parallel data line. Subsequent data processing is completed by the ARM core CPU, which can give play to the advantages of CPU digital computing; FPGA simultaneously extracts clock information from the rising and falling edge information of the data frame, and can complete the phase locking function of the distribution network detection device without clock line or clock signal output. Improve the compatibility of this device with different devices.

[0054] After the device is connected to the detection equipment and starts to transmit data, it first determines the starting and ending positions of the message frame, then extracts the data segment and the verification segment, and extracts the time mark, type symbol and data body after determining that the data is correct and stores them in the memory. The controller of the device of the present invention reads the stored data to standardize the sent data frame. The sent data frame is a binary structure with a length of 32 bits, which are the start segment, address segment, time mark segment, type segment, data segment, verification segment and end segment from left to right. The length of the characters allocated to each segment can be flexibly adjusted. If a segment is not suitable for a certain detection device, all are set to "0", and finally the standardized data frame is transmitted through the signal transmitter 2. After receiving it, the user's mobile phone or computer terminal will restore it to test data.

[0055] The present invention is developed based on the fully digital controller and the latest technology of the Internet of Things. With this device as a bridge, it can open up the efficient data collection of different distribution network instruments, internal and external network interaction, physical ID association and other contents. At the same time, as a supporting platform for miniaturized live detection instruments, the device supports infrared, ultrasonic and other miniaturized live detection instruments to interact with mobile terminals, which can realize convenient and efficient operations of basic teams. The device can improve the operation guarantee capability of the distribution network and reduce the operation and maintenance costs, effectively ensuring the strong operation of the city and county networks.
