Description

Technical Field

[0001] The invention relates to the technical field of measuring tapes, and more particularly to an insulating measuring tape and a measuring method. Background Art

[0002] In daily inspection and maintenance, maintenance personnel often use traditional metal tape measures to measure the size of equipment. Since the equipment is energized, there is a risk of electric shock when operators measure. In addition, traditional metal tape measures have relatively single functions, and operators usually need to carry more tools. When changing tools, they are easy to drop into the equipment, which poses certain safety hazards.

[0003] Traditional measuring equipment can provide measurements with a certain degree of accuracy, but they have the following shortcomings: Operational complexity: Traditional equipment usually requires professionals to set up and operate, including setting the measurement range, selecting the appropriate test voltage, etc.; Novices or non-professionals are prone to errors during operation, resulting in inaccurate measurements; Volume and weight issues: Many traditional instruments are bulky and not easy to carry, and are not suitable for on-site operations at construction sites or remote areas. Their fixed use locations limit flexible applications and cause waste of resources. Slow perception and response: These devices are usually unable to record and analyze measurement data in real time, and can only be recorded manually after the measurement is completed, which can easily lead to data omissions or errors; Lack of intelligence: Most traditional equipment does not have the function of connecting and sharing data with other devices (such as mobile phones or computers), which limits the use and analysis of data;

[0004] Therefore, the present application provides a convenient and efficient insulation measurement tool that can quickly measure the size of insulating equipment. At the same time, based on the Internet of Things technology, an electronic measurement and real-time data display system is integrated in the insulation measurement tape to reduce human errors, improve measurement accuracy, achieve miniaturization and portability, adapt to the needs of the on-site environment, and facilitate operation and carrying.

[0039] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0040] The present invention provides an insulating measuring tape and a measuring method, such as Figure 1 As shown, it comprises: a tape measure body 1; a mounting shaft 2 is rotatably arranged in the tape measure body 1; a measuring ruler 3 is wound around the mounting shaft 2; a driving assembly 4 for driving the mounting shaft 2 to rotate forward or reverse is arranged in the tape measure body 1; the driving assembly 4 is detachably connected to the tape measure body 1, and the output end of the driving assembly 4 is fixedly connected to the mounting shaft 2; a measuring port 5 for extending the measuring ruler 3 is opened on the tape measure body 1; a clamping slot 7 is arranged on the measuring port 5; a clamping member 6 is arranged on the head end of the measuring ruler; the clamping member 6 can be clamped with the clamping slot 7; when the clamping member 6 is in clamping with the clamping slot 7, the head end of the measuring ruler 3 is fixed at the measuring port 5; an intelligent measuring assembly 8 for cooperating with the measuring ruler 3 to measure the length of an object is arranged inside the tape measure body 1; an infrared detector 9 for measuring angles is also arranged on one side of the tape measure body 1; the detection end of the infrared detector 9 is on the same horizontal line as the measuring port 5.

[0041] In the first embodiment, the operator measures the object by pulling out the measuring ruler 3 from the measuring port 5 on the tape measure body 1. The measured value can be intuitively displayed through the scale on the measuring ruler 3. At the same time, the intelligent measuring component 8 arranged inside the tape measure body 1 measures the rotation amplitude of the installation shaft 2 around which the measuring ruler 3 is arranged to obtain the measured value and provide more accurate measurement data. At the same time, the infrared detector 9 installed outside the tape measure body 1 can be used to measure angles. The position of the card slot 7 on the tape measure body 1 and the card connector 6 ensure that the measuring ruler 3 can be firmly fixed on the tape measure body 1 when it is on standby and not in use.

[0042] Specifically, the tape measure body 1 and the measuring ruler 3 are made of insulating materials, such as plastic, etc., to better protect the life and property safety of the operator.

[0043] Furthermore, the intelligent measuring component 8 includes: a detection member 81 for detecting the rotation amplitude of the installation shaft 2, and a plurality of sensor members 82 equidistantly arranged at the bottom of the measuring ruler 3 for detecting the distance between the bottom of the measuring ruler 3 and the measured object; the plurality of sensor members 82 are fixedly connected to the bottom of the measuring ruler 3; the detection member 81 is detachably connected to the tape measure body 1; and the detection end of the detection member 81 is fixedly connected to the installation shaft 2.

[0044] Specifically, the detection member 81 detects the rotation amplitude of the mounting shaft 2 to obtain the distance the measuring ruler 3 is pulled out, thereby detecting the accurate value of the measurement. Compared with measuring only with the measuring ruler 3, the measured data can be more accurate. A plurality of sensor members 82 are equidistantly arranged at the bottom of the measuring ruler 3, so that during the measurement process, the operator can always keep the measuring ruler 3 parallel to the object being measured, thereby ensuring the accuracy of the measurement data.

[0045] Furthermore, the driving assembly 4 includes: a driving member 41 and a reset button 42 arranged inside the tape measure body 1; the driving member 41 is detachably connected to the tape measure body 1; the output end of the driving member 41 is fixedly connected to the mounting shaft 2; the reset button 42 is arranged on the outside of the tape measure body 1; the reset button 42 is electrically connected to the driving member 41.

[0046] In the second embodiment, after the measurement is completed, the reset button 42 on the tape measure body 1 is activated to start the driving member 41, thereby driving the mounting shaft 2 to rotate, so as to complete the operation of retracting the measuring ruler 3. Compared with the traditional mechanical retraction, the electric retraction method is smoother and more uniform, preventing damage to the sensor 82 and the measuring ruler 3, and further improving the service life.

[0047] Furthermore, a display module 10 for displaying real-time measurement data is also provided on the outer side of the tape measure body 1; the display module 10 is detachably connected to the tape measure body 1; and the display module 10 is electrically connected to the intelligent measurement component 8 and the infrared detector 9, respectively.

[0048] Specifically, the display module 10 uses an LCD screen, which can display information such as length, angle, and ambient temperature and humidity in real time. The display module 10 is fixed to the tape measure body 1 through a magnet and a card slot 7 structure, which is convenient for users to disassemble and replace. At the same time, the display module 10 has a built-in battery and can be electrically connected to the intelligent measurement component 8 and the infrared detector 9 through a circuit board to ensure real-time data update.

[0049] Furthermore, a temperature and humidity sensor 11 for monitoring and measuring the temperature and humidity of the environment is also provided on the outer side of the tape measure body 1 ; the temperature and humidity sensor 11 is fixedly connected to the tape measure body 1 .

[0050] Specifically, the temperature and humidity sensor 11 adopts a small digital sensor, which can monitor the temperature and humidity in real time. The sensor is fixed at the lower part of the tape measure body 1, connected to the display module 10 through an embedded cable, and transmits data in real time. The installation position of the sensor ensures that it will not interfere with other measurement functions, which is convenient for the operator to make adjustments when the environmental conditions change.

[0051] Furthermore, the tape measure body 1 is also provided with a wireless communication module for connecting with a communication terminal.

[0052] Furthermore, the sensor 82 may be a photoelectric sensor or an infrared sensor.

[0053] Optionally, a night light for night lighting is also provided on the tape measure body 1; the night light can provide lighting when the ambient light is insufficient, further increasing the scene adaptability.

[0054] In other embodiments, a mechanical reset handle is also provided. The mechanical reset handle is arranged on the outer side of the tape measure body 1 and is fixedly connected to the mounting shaft 2. The measuring scale 3 can be manually reset by the mechanical reset handle to adapt to working conditions in adverse environments.

[0055] A measuring method based on the above-mentioned insulating measuring tape comprises:

[0056] Step A, start the button on the tape measure body 1 to connect with the communication terminal using the wireless communication module, and at the same time, the temperature and humidity sensor 11 on the tape measure body 1 automatically calibrates the temperature and humidity of the measurement environment;

[0057] Step B, separating the clamping piece 6 on the measuring ruler 3 and the clamping slot 7 on the measuring tape body 1, so as to start measuring with the unlocked measuring ruler 3;

[0058] Step C, the measuring ruler 3 is pulled out and measured on the object to be measured. During the measurement process, the intelligent measuring component 8 detects the pulled out distance to obtain accurate measurement data. At the same time, if there are any operational problems during the measurement process, the operator is reminded to deal with them in time to avoid the occurrence of excessive errors;

[0059] Step D, after the measurement is completed, the measurement data is visually viewed through the scale on the measuring ruler 3, and the precise measurement data and predicted measurement error obtained by the intelligent measurement component 8 can also be displayed on the display screen; at the same time, the measurement results are sent to the communication terminal through the wireless communication module;

[0060] Step E: After obtaining the measurement result, press the reset button 42 on the tape measure body 1 to make the driving member 41 drive the mounting shaft 2 to rotate, thereby rewinding the measuring ruler 3 and making the clamping member 6 on the measuring ruler 3 re-engage with the clamping slot 7 of the tape measure body 1 to realize the operation of restoring the measuring ruler 3.

[0061] Optionally, when there is an operational problem during the measurement process in step C, the operator is reminded to handle it in time to avoid the occurrence of excessive errors. The specific implementation process is as follows:

[0062] C1. Taking the head end of the measuring ruler 3 as the base point, each X sensor elements 82 is regarded as a measuring partition, and the data set Q of each measuring partition is measured. n =X1,X2,X3,X X , X i represents the distance between the bottom of the measuring ruler 3 and the measured object measured by the sensor 82, and n represents the total number of measurement partitions in this measurement, and n is an integer greater than or equal to 1;

[0063] C2. Through the data set Q n Get the average value of the measurement area To ensure the accuracy of the measurement data, the difference between the average values ​​of all measurement partitions in the measurement process should be less than the specified error value k; when the difference between the average values ​​of all measurement partitions is less than the specified error value k, it means that there is a small error in the measurement, and the signal mark of "small error" is output;

[0064] C3. When the sum of the differences of the average values ​​of all measurement partitions is greater than the error value k, it means that there is a large error in the measurement, and a signal flag of "large error" is output;

[0065] C4, when the average value of the adjacent measurement partition is greater than z, that is, μ n -μ n-1 ≧z, it indicates that there is a large error interference in the adjacent measurement partition. The display module 10 reminds the operator to process the measurement partition in time to avoid affecting the measurement data. It indicates that there is a certain error in the measurement and outputs a signal mark of "certain error".

[0066] Optionally, the precise measurement data and predicted measurement error obtained by measuring the intelligent measurement component 8 are displayed on the display screen in step D. The specific implementation process is as follows:

[0067] D1. When the output is a signal mark with a large error, it means that the error ratio between the actual value and the measured data is ±17%-±22%;

[0068] D2. When the output is a signal mark of a certain error, it means that the error ratio between the actual value and the measured data is ±10%-±13%;

[0069] D3. When the output is a signal mark with a smaller error, it means that the error ratio between the actual value and the measured data is ±3%-±7%.

[0070] Specifically, when there is a small error, it may be due to improper operation that causes the measuring ruler 3 to be rolled up. At this time, the operator needs to flatten the measuring ruler 3 to ensure the accuracy of the measurement data.

[0071] When there is a large error, it may be that part of the measuring ruler 3 is far away from the measured object, and the measuring ruler 3 as a whole cannot be kept relatively parallel to the measured object. In this case, a large error will appear in the measurement result, and re-measurement is required.

[0072] Specifically, when determining the measurement data to be recorded last, the temperature and humidity at the measurement time point are combined to further confirm the measurement data, so as to avoid the situation where certain electrical materials are deformed under certain temperature and humidity conditions, resulting in measurement data that does not conform to reality.

[0073] The insulating measuring tape and measuring method of the present invention are equipped with an intelligent measuring component 8, which can automatically calibrate and detect environmental factors (such as temperature and humidity) during the measurement process, thereby significantly improving the measurement accuracy; each measuring partition of the measuring ruler 3 is provided with a sensor, which can monitor the distance between the measuring object in real time, and use a multi-point sampling method to reduce the influence of local errors, ensuring that the final measurement result is more accurate. At the same time, by monitoring the difference in the average value of the measuring partition, when it is detected that the error exceeds the preset range, a warning will be issued in time to ensure that the operator can adjust the measurement strategy in time.

[0074] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
