Small precision measuring instruments are being used for various dimensional measurements. Examples of small precision measuring instruments include digital vernier calipers, micrometers, indicators, and electronic scales.

Among them, the digital vernier caliper has the main chuck and the vernier slidably mounted on the main body. On the main body, an outer trough is formed on the lower side of the end portion to measure the outer diameter of the workpiece, and an inner trough is formed on the upper side of the end portion for measuring the inner diameter of the workpiece. Also, in the vernier, the outer tank and the inner tank corresponding to the outer tank and the inner tank are formed, respectively.

Dimensions measured through the outer trough and inner trough are displayed on the display on the vernier.

Conventionally, the measurement values recorded on the display of the digital vernier caliper are manually recorded by the user, and the measured values are analyzed and managed. However, the process of recording the measured values is troublesome and errors are generated in the process of recording in a manual manner.

Accordingly, a technique has been developed in which a data communication port is formed in a vernier caliper and connected to a user terminal such as a PC via a wired cable to transmit measurement values. However, due to the connection of the wired cable to the vernier caliper, it is inconvenient to measure the dimension, and there is a limit to the movement of the device during the measurement according to the length of the wired cable, and there is a risk of breakage by the cable being caught between other devices.

To solve the disadvantages of data transmission using wired cable, a product with a Bluetooth module on a digital vernier caliper was developed. However, this is a disadvantage in that the unit price is expensive, the conventional digital vernier caliper user is burdened to replace the equipment, the compatibility of the program is poor when the manufacturer is different, and other functions other than the data transmission can not be added.

The multifunctional data transmission module 1000 for a precision measuring instrument according to an embodiment of the present invention is connected to the data communication port 11 of the precision measuring instrument 10 to measure the measurement data measured by the precision measuring instrument 10 The first module 100, the second module 200, and the third module 300, which can selectively transmit the additional function to the user terminal 20 through communication.

The first module 100 is configured to transmit measurement data obtained by measuring the dimensions of the measurement object or the like to the user terminal 20 in the precision measurement equipment 10. Here, the precision measuring equipment 10 is a digital measuring equipment. In the present embodiment, the digital vernier calipers are exemplified. However, the precision measuring equipment 10 may be a measuring instrument having a data communication port 11 such as a micrometer, an indicator, . The user terminal 20 may be understood to mean any type of terminal device supporting a Bluetooth communication function such as a smart phone, a PDA, or a laptop, a PC, or the like.

The first module 100 includes a terminal 110, a control unit 120, a switch unit 130, and a first expansion port 140.

The terminal 110 is connected to the precision measuring equipment 10. A digital vernier caliper as a precision measuring instrument 10 is generally provided with a data communication port 11 for transferring measurement data to a PC or the like using a wired cable and a terminal 110 is connected to the data communication port 11 . By connecting the terminal 110 to the data communication port 11, it is possible to transmit the measurement data through the wireless communication through the control unit 120.

The control unit 120 receives measurement data measured by the precision measuring equipment 10 and transmits the measurement data to the user terminal 20. [ The control unit 120 includes a Bluetooth module for Bluetooth communication with the user terminal 20. The controller 120 controls the precision measuring instrument 10 to measure the measured value when the user touches the first switch 131 while the terminal 110 is connected to the data communication port 11 and the Bluetooth communication with the user terminal 12 is connected. And transmits the measurement data to the user terminal 20 using the Bluetooth communication.

The switch unit 130 includes a first switch 131 and a second switch 132 for transmitting measurement data to the user terminal 20 and canceling transmission.

The first switch 131 is configured to transmit the measurement data received by the controller 120 to the user terminal through Bluetooth communication when the user operates the terminal through the push operation or the like. That is, the present invention does not always transmit measurement data to the user terminal 20, but is transmitted to the user terminal 20 only when the first switch 131 is activated. Therefore, when a clear error occurs due to a mistake or the like in the measurement process, it is possible to prevent the cumbersome process from unnecessarily deleting the measurement data after inputting the measurement data.

The second switch 132 is a configuration for deleting (canceling) the measurement data transmitted to the user terminal 20 when the user operates the terminal through a pushing operation or the like. The user terminal 20 is installed and driven with a program (for example, an excel program or a produced program) to which the received measurement data is inputted. The measurement data transmitted to the user terminal 20 by operating the first switch 131 is input to the program and when the second switch 132 is operated, the first switch 131 is operated to measure the transmitted measurement Data is deleted. Accordingly, since the user does not have to delete the erroneously transmitted data directly on the user terminal 20, it is very convenient to manage the measurement data and the efficiency is improved.

The first expansion port 140 is a configuration in which the second module 200 or the third module 300 is connected. The first expansion port 140 will be described later.

The first module 100 may include a terminal 110, a control unit 120, a switch unit 130, and a first expansion port 140, so that the first module 100 may be small. Particularly, since the ultra-small Bluetooth module is developed due to the development of the Bluetooth module, the size can be made very small, and even if connected to the data communication port 11, there is no influence on the measurement of the measurement object.

In addition, since the first module 100 can be connected to the precision measuring instrument 10, the measurement data can be transmitted to the user terminal 20, so that it is not necessary to change the equipment to wirelessly transmit the data, Easy and free equipment movement is possible.

The second module 200 supplies power to the first module 100 and informs the user of whether the measurement data is transmitted or canceled. The second module 200 includes a second terminal 210, a battery 220, a notification means 230, and a second expansion port 240.

The second terminal 210 is detachably connected to the first expansion port 140. When the second terminal 210 is connected to the first expansion port 140, power is supplied from the battery 220 to the first module 100 . It is possible to avoid frequent charging of the precision measuring equipment 10 by using the battery 220 which is an external power source other than the power source of the precision measuring equipment 10 for transmitting the measurement data and driving the switch unit 130. [

The notifying means 230 is a configuration for informing the user whether the measurement data is transmitted or canceled. The notifying means 230 may be realized by at least one of a light emitting module, an alarm sound module, and a vibration module. For example, in the case of a light emitting module, the LED may emit green when measurement data is transmitted, and the LED may emit red when measurement data transmission is canceled. Alternatively, the number of times of emission may be set to be different.

Further, when using the alarm sound module, it is possible to notify the transmission and the cancellation of the measurement data through different alarm sounds. Meanwhile, it is also possible to notify the user of the transmission of the measurement data and the cancellation of the transmission through the program installed in the user terminal. It is possible to inform the user by generating different alarm sounds when the measurement data is transmitted and when the transmission data is canceled, and to generate the same alarm sound as the alarm sound generated at the user terminal. That is, when the transmission and the transmission of the measurement data are canceled, the notification means 230 and the user terminal 20 generate the same alarm sound, respectively, so that it is possible to know more clearly whether the measurement data is transmitted or canceled.

Since the notification means 230 does not require the user to check whether transmission / transmission of the measurement data is canceled, the operation efficiency is greatly improved

Meanwhile, the notifying means 230 is not necessarily implemented together in the second module 200, but may also be implemented as an extended function through the third module 300. For example, if the light emitting module, the alarm sound module, and the vibration module are all implemented, the overall unit price can be increased. It is not necessarily implemented as a vibration module, but may be useful for a user having a relatively low auditory function, so that it is separately implemented in the third module 300 as described later, .

The second expansion port 240 is connected to the third module 300 in order to perform additional functions in addition to the functions of the first module 100 and the second module 200. The second expansion port 240 is provided in the same configuration as the first expansion port 140.

5 is a schematic diagram of a multifunctional data transmission module for precision measurement equipment according to an embodiment of the present invention.

The third module 300 is connected to the second module 200 or the first module 100 to perform additional functions in addition to the functions implemented in the first module 100 and the second module 200. In this embodiment, the third module 300 includes a third terminal 310 and an NFC tag.

And the third terminal 310 is detachably connected to the second expansion port 240. The third terminal 310 may be connected to the first expansion port 140 as well as the second expansion port 240 because the third terminal 310 is formed of the same terminal as the second terminal 210. That is, the present invention can selectively perform a plurality of functions by providing a plurality of modules that can be connected to the first expansion port 140 and perform different functions, and can connect a plurality of modules in series, May be performed simultaneously. In this embodiment, the third terminal 310 is connected to the second expansion port 240. That is, the second module 200 is connected to the first module 100, and the third module 300 is connected to the second module 200 to perform all the functions of the respective modules.

The third module 300 is equipped with an NFC tag. The NFC tag is a configuration for collecting measurement information according to a user inputting user's information. Specifically, the user can use the user information card in a work environment. The user information card records the identity information of the user.

When the user recognizes the user information card in the NFC tag of the third module 300 before measurement of the measurement object and then measures it using the precision measuring instrument 10 and presses the first switch 131, And information such as the measurement time are also input. Since the operation method of the precision measuring instrument 10 and the measurement habit are different for each user, an aberration may occur in the measurement result for each user.

However, since the user information and the measurement result are input together through the NFC tag, it is possible to confirm how the measurement result is different according to the user, and more precise data can be obtained through the modification of the measurement process.

A third expansion port 320 may be formed in the third module 300. The third expansion port 320 is provided in the same manner as the first expansion port 140 or the second expansion port 240, so that an additional module can be connected.

Next, a multifunctional data transfer module for a precision measuring instrument according to a second embodiment of the present invention will be described.

The multifunctional data transmission module 1000 for a precision measuring instrument according to an embodiment of the present invention is connected to the data communication port 11 of the precision measuring instrument 10 to measure the measurement data measured by the precision measuring instrument 10 The first module 100, the second module 200, and the third module 300, which are transmitted to the user terminal 20 through communication. The present embodiment differs from the first embodiment in that the control unit differs from that in the first embodiment, so that duplicated description of the same configuration will be omitted and only differences will be described.

The control unit 120 receives measurement data measured by the precision measuring equipment 10 and transmits the measurement data to the user terminal 20. [ The control unit 120 includes a Bluetooth module for Bluetooth communication with the user terminal 20. The controller 120 controls the precision measuring instrument 10 to measure the measurement value when the user touches the first switch 131 while the terminal 110 is connected to the data communication port 11 and the Bluetooth communication with the user terminal 20 is connected. And transmits the measurement data to the user terminal 20 using the Bluetooth communication.

The control unit 120 differs from the first embodiment in that measurement data is corrected and transmitted to the user terminal 20. [

A precision measuring instrument 10 such as a digital vernier caliper or a micrometer is intended to precisely measure dimensions such as an outer diameter and an inner diameter of an object to be measured. However, in the working environment, due to temperature, humidity, and other environmental factors, the object to be measured may expand or shrink, resulting in minute changes, which means an error in the measurement data.

In this embodiment, the controller 120 measures the error rate of the precision measuring instrument 10 according to the surrounding environment. Specifically, the dimensions of the object to be measured are measured using a measuring instrument more precisely than the precision measuring instrument 10, and the error rate is measured from the measurement data obtained by measuring the measurement object and the dimensions of the object to be measured through the precision measuring instrument 10. At this time, measurement of the error is performed by measuring the dimensions while varying the conditions such as the temperature and humidity of the working environment.

The control unit 120 reflects the error rate on the measurement data and transmits it to the user terminal 20. [ When the precision measuring instrument 10 measures the dimensions of the object to be measured and the like, this value is displayed on the display on the precision measuring instrument 10. If the user activates the first switch 131, the control unit 120 transmits correction data reflecting the error rate to the measurement data displayed on the display to the user terminal 20, Lt; / RTI > That is, a value different from the measurement data displayed on the display on the precision measuring equipment 10 is transmitted to the user terminal 20. [

The correction of the measurement data of the control unit 120 described above may be provided for the user to selectively use.

Therefore, according to the present invention, there is provided a multifunctional data transmission module connected to a precision measuring instrument and capable of selectively transmitting measurement data measured by a precision measuring instrument to a user terminal through wireless communication and selectively expanding an additional function do.
