FIG. 1 illustrates a monitoring device 100 according to an exemplary embodiment of the present invention. Referring to FIG. 1, the monitoring device 100 may include a magnetic sensor 200, a slave module 300, a master module 400, and an interface module 500.

The magnetic sensor 200 may be installed in an applicator and sense movement of a magnetic body provided in the applicator. As an example, the applicator may have a stationary unit and a moving unit which moves up or down, and the magnetic sensor 200 may be installed in the stationary unit of the applicator and sense movement of a magnetic body provided in the moving unit which moves up or down. The magnetic sensor 200 may sense a magnetic field which is generated when the magnetic body moves up or down. That is, when the magnetic body moves up and down once, the magnetic sensor 200 may recognize an up and down movement number of 1. At least one magnetic sensor 200 may be provided in each of a plurality of applicators, and it is possible to know the number of strokes or the number of uses of an applicator and an applicator fixture installed on the applicator using mobility information, specifically, up and down movement number information of the magnetic body, of the magnetic body measured by the provided magnetic sensor 200.

The slave module 300 may be connected to the magnetic sensor 200 wiredly or wirelessly and receive measured mobility information of a magnetic body. The mobility information of a magnetic body includes up and down movement number information of the magnetic body.

Also, the slave module 300 may include a radio frequency identification (RFID) reader (not shown). The slave module may recognize an RFID tag installed in an applicator fixture using the RFID reader and receive or acquire identification information of the applicator fixture from the recognized RFID tag.

The slave module 300 and the magnetic sensor 200 are paired and may check and transfer the identification information of the applicator fixture received through the RFID reader and the number of strokess or the number of uses of the applicator fixture corresponding to the identification information.

The slave module 300 may include an alarm unit (not shown). The alarm unit (not shown) may output an alarm in at least one of auditory (e.g., a speaker), visual (e.g., a lamp), and tactile (e.g., vibrations) manners. The slave module 300 may output an alarm through the alarm unit when identification information is changed as identification information of an applicator fixture is received for the first time through the RFID reader or an applicator fixture is replaced with another applicator fixture.

The master module 400 may receive identification information of an applicator fixture and mobility information of a magnetic body corresponding to the identification information from the at least one slave module 300.

Specifically, the master module 400 may include a short-range communication module (not shown) and receive the identification information and the mobility information from the at least one slave module 300. The short-range communication module (not shown) may include at least one of a Bluetooth module, an RFID module, a ZigBee module, a near-field communication (NFC) module, and a Wi-Fi module. The master module 400 may receive and acquire identification information and corresponding mobility information of at least one applicator fixture and sort or arrange the identification information and the mobility information.

The interface module 500 may be connected to the master module 400 wiredly or wirelessly and receive the identification information of the at least one applicator fixture and the corresponding mobility information. For example, the interface module 500 and the master module 400 may be connected through a universal asynchronous receiver-transmitter (UART), but the present invention is not limited thereto.

The interface module 500 may output the received identification information of the at least one applicator fixture and the corresponding mobility information on a display unit (not shown). The mobility information includes up and down movement number information of a magnetic body.

Referring to FIGS. 2 and 3, an example of a monitoring interface of up and down movement number information corresponding to identification information of at least one applicator fixture displayed on a display will be described below.

FIGS. 2 and 3 illustrate monitoring interfaces showing identification information and up and down movement number information of at least one applicator fixture according to an exemplary embodiment and another exemplary embodiment of the present invention.

Referring to FIG. 2, it is possible to see that up and down movement number information corresponding to identification information of applicator fixtures is displayed. Displayed cells may be shown in different colors according to up and down movement number information. For example, when an applicator fixture is not moved up and down, that is, when an up and down movement number information value is 0, the cell may be shown in a first color (e.g., white), when an up and down movement number information value is 1 to 4999, the cell may be shown in a second color (e.g., green), when an up and down movement number information value is 5000 to 9999, the cell may be shown in a third color (e.g., orange), and when an up and down movement number information value is 9999 or more, the cell may be shown in a fourth color (e.g., red). In this case, an applicator fixture shown in the fourth color (e.g., red) may be considered to have reached the end-of-life phase, and a user may be induced to replace the applicator fixture. A user may easily recognize an applicator fixture which has not currently operated from the white color shown in the display unit and replace an applicator fixture, which has reached the end-of-life phase, shown in red in the display unit.

Meanwhile, the reference values for color coding, corresponding colors, sections, etc. have been described as an example, and it is obvious that the reference values, corresponding colors, sections, etc. may be appropriately changed according to characteristics of each applicator fixture and a user's demand.

Referring to FIG. 3, it is possible to see that up and down movement number information is displayed according to identification information of applicator fixtures and the types of applicators (e.g., anvils) on which applicator fixtures are installed. In other words, up and down movement number information is displayed according to the types of installed applicators (e.g., anvils), and when the same applicator fixture is installed on different applicators, an up and down movement number may be displayed regarding each of the applicators. Other matters are the same as described with reference to FIG. 2.

Meanwhile, when up and down movement number information exceeds a threshold value which requires replacement, the interface module 500 may control an alarm unit of a slave module corresponding to, for example, an applicator fixture shown in the fourth color (e.g., red) in FIG. 2 and output an alarm. As described above, the alarm may correspond to any one of auditory (e.g., a speaker), visual (e.g., a lamp), and tactile (e.g., vibrations) manners. Although not shown in the drawing, it is obvious that each of the slave module 300 and the master module 400 may include a display unit and display up and down movement number information and the like of a corresponding applicator fixture through the display unit.

FIG. 4 illustrates a monitoring method according to an exemplary embodiment of the present invention.

Referring to FIG. 4, it is possible to receive identification information of at least one applicator fixture and mobility information of a magnetic body corresponding to the applicator fixture (S100). The mobility information of the magnetic body may include up and down movement number information of the magnetic body. The up and down movement number information of the magnetic body may correspond to the number of strokes or the number of uses of the applicator fixture. It is determined whether the received up and down movement number information is a first threshold value or more (S110). The first threshold value is 1 and may indicate that the applicator has operated at least once. When the received up and down movement number information is not the first threshold value or more, the identification information and the up and down movement number information may be displayed, and the cell may be shown in a third color (e.g., white) (S120). When the received up and down movement number information is the first threshold value or more, it is determined whether the up and down movement number information is a second threshold value or more (S130). When the received up and down movement number information is not the second threshold value or more, the identification information and the up and down movement number information may be displayed, and the cell may be shown in a second color (e.g., green) (S140). The second threshold value is related to the number of strokess or the life of the applicator fixture resulting from the use and may be determined according to characteristics of the applicator fixture. In other words, when the up and down movement number information is the second threshold value or more, it is necessary to replace the applicator fixture. When the received up and down movement number information is the second threshold value or more, the identification information and the up and down movement number information may be displayed, and the cell may be shown in a first color (e.g. red) (S150). Also, an alarm unit may provide a notification that it is necessary to replace the applicator fixture in at least one of auditory (e.g. a speaker), visual (e.g. a lamp), and tactile (e.g. vibrations) manners (S160).

Although a case of replacing an applicator fixture when the number of strokes or the number of uses of the applicator fixture exceeds a preset number of strokes or a preset number of uses has been described as an example, the present invention is not limited thereto. According to the same technical spirit, it is obvious that when the number of strokess or the number of uses of an applicator fixture exceeds a preset value, a corresponding applicator may be replaced.

Exemplary embodiments of the present invention disclosed herein and the drawings are specific examples to facilitate description of the present invention and aid in understanding the present invention and are not intended to limit the scope of the present invention. Therefore, the scope of the present invention should be construed as encompassing not only the exemplary embodiments disclosed herein but also all modifications or alterations derived from the technical spirit of the present invention.
