The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

Referring to fig. 1 and fig. 2, the present invention provides an abnormal electric quantity checking system, which includes an acquisition terminal 10 and a plurality of handheld terminals 20;

the collection terminal 10 includes a gauge head case 17 and a gauge body case 18. The meter head shell 17 is provided with a leakage current acquisition module 11. The clock module 13, the first power module 14, the data processing module 12, the data storage module 16 and the first wireless communication module 15 are arranged in the watch body shell 18.

Specifically, the leakage current collecting module 11 on the header housing 17 in the collecting terminal 10 includes an open-close type ring transformer 111, and the open-close type ring transformer 111 includes a left side measuring clamp and a right side measuring clamp. An open-close button is arranged on the left side of the watch body shell 17. The staff presses the button that opens and shuts, and the left side of open and shut formula ring transformer 111 measures the pincers and opens to the outside, can manually put into open and shut formula ring transformer 111 opening with the circuit of measuring this moment. After the worker releases the hand opening and closing button, the opening and closing type ring transformer 111 is automatically closed, so that the whole acquisition terminal 10 is automatically hung on a line under the action of gravity. The open-close type ring transformer 111 arranged on the acquisition terminal 10 can take the acquisition terminal off the line after the detection task is completed, so that the acquisition terminal 10 can be used for multiple times.

In a working state, the leakage current collecting module 11 on the collecting terminal 10 measures the leakage current value in real time and uploads the measured leakage current data to the data processing module 12. The data processing module 12 receives the leakage current data measured by the leakage current collecting module 11 and the time information of the clock module 13 at the same time, and processes the received leakage current data and the clock information, so that the measured data is matched with the time, and the accuracy of the measurement result is ensured. The data processing module 12 uploads the processed data to the data storage module 16. The data storage module 16 stores the data uploaded by the data processing module in a partitioned manner and provides communication data to the first wireless communication module 15. The first power module 14 is configured to supply power to the leakage current collecting module 11, the clock module 13, the data processing module 12, the data storage module 16, and the first wireless communication module 15 in the collecting terminal 10. The first wireless communication module 15 communicates with the second wireless communication module 21 in the handheld terminal 20 by radio, so that the handheld terminal 20 and the collection terminal 10 can communicate with each other.

The handheld terminal 20 includes a second wireless communication module 21, a signal processing module 22, a display module 23 and a second power module 24. The second power module 24 is used for supplying power to the handheld terminal 20, so as to ensure the normal operation of the second wireless communication module 21, the signal processing module 22 and the display module 23. The second wireless communication module 21 receives the data signal transmitted by the first wireless communication module 15 and transmits the received data signal to the signal processing module. The signal processing module 22 receives and processes the signal sent by the second wireless communication module 21, and outputs the processed signal to the display module according to the instruction. The handheld terminal 20 may receive data signals from multiple acquisition terminals simultaneously. Therefore, the signal processing module 22 of the handheld terminal provides at least two output modes after receiving the data signal provided by the second communication module 21. One of the output modes is to output the detection data of one of the acquisition terminals 10 in a certain time on the display module 23; the second output mode is to provide data detected by multiple acquisition terminals 10 at a certain time on the display module 23, and the specific time can be flexibly switched. The signal processing module 22 of the handheld terminal 20 receives the data and automatically compares the data, and provides the compared data to the detection personnel.

The hand-held terminal 20 and the collecting terminal 10 can form a communication network, and the hand-held terminal 20 has a function of inquiring all the measurement data stored in the data storage module 16 of the collecting terminal 10. But the acquisition terminal 10 does not have a function of inquiring data in the hand-held terminal 20 or other data in the acquisition terminal 10 to prevent data leakage.

When the handheld terminal 20 views data stored in one of the collection terminals 10 in the communication network, the signal processing module 22 may output a plurality of viewing modes, such as a comparison table or a measurement curve, after processing the data.

Particularly, in order to better solve the problem of checking the leakage place under the complex conditions, the open-close type ring transformer 111 should have higher measurement precision, and can have the function of checking the small-current intermittent leakage place.

Because the handheld terminal 20 can receive the detection data of a plurality of collecting terminals 10 at the same time, the tester does not need to run back and forth between the measuring points, and the data uploaded by the collecting terminals 10 can be collected by holding the handheld terminal 20 in the communication range. After the handheld terminal 20 summarizes the data, the staff can find the range of the leakage line through data comparison. If the worker finds that the leakage data of two adjacent collection terminals 10 on the same branch line are different, the worker explains that a leakage point exists in the line range between the two collection terminals 10. After the range of the leakage line is found, the worker hangs the acquisition terminal 10 again in the determined range of the leakage line, and the leakage is detected again, so that the leakage place can be determined quickly and efficiently.

For convenience of carrying and use, the power source in the first power module 14 of the acquisition terminal 10 and the second power module 24 of the handheld terminal 20 includes batteries. Specifically, the battery is a rechargeable lithium battery.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
