After step S90, the mobile terminal 30 transmits the factory facility control information received from the manager to the local active black box 10 (S100).

Then, the local active black box 10 receives the factory facility control information for each identification ID from the mobile terminal 30 and controls the PLC operation of the factory facility (S110).

FIG. 10 is a diagram showing a concept of a factory equipment monitoring system S using a wireless communication-based control apparatus, in particular, a local active black box according to an embodiment of the present invention. Referring to FIGS. 2 to 10, the local active black box 10 can provide an integrated service including a function of a central control server in an existing active black box. In other words, the conventional active BlackBox includes a combination of MES (Manufacturing Execution System) data corresponding to PLC (Programmable Logic Controller) driving data of a plant facility and a composite sensor (temperature / humidity, gas, , Co2, and electric power sensor), CCTV, etc., and it is possible to inquire the collected data from the central control server located at a remote location in real time. In the case of a direct connection (1: N ).

On the other hand, the factory facility monitoring system S utilizing the local active black box 10 proposed in the present invention can store and collect data collected by being included in the active black box 10 without having a central control server at a remote place. It is possible to provide a system which can be inquired.

To solve this problem, the problem of capacity limitation, which is considered as a disadvantage of the local system, can solve the problem by providing a large capacity SSD card and an external HDD, which are the extended memory devices 20 connected to a separate expansion port outside the ActiveBlackbox. Can be periodically backed up so that data can be effectively managed.

In addition, if a problem occurs in the equipment due to the adoption of the data double structure method, the problem of data loss can be prevented by replacing with another equipment.

A push notification may be sent when the mobile terminal 30 is connected to the network when the push notification server is separately formed so as to send an important notification to the administrator.

As a result, compared to the existing active black box, there is no separate central control server at the remote place, thus reducing the cost. In addition, the collected data is not exposed to the outside, providing security advantages.

The present invention can also be embodied as computer-readable codes on a computer-readable recording medium. A computer-readable recording medium includes all kinds of recording apparatuses in which data that can be read by a computer system is stored.

Examples of the computer-readable recording medium include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device and the like, and also implemented in the form of a carrier wave (for example, transmission over the Internet) .

The computer readable recording medium may also be distributed over a networked computer system so that computer readable code can be stored and executed in a distributed manner. And functional programs, codes, and code segments for implementing the present invention can be easily inferred by programmers skilled in the art to which the present invention pertains.

As described above, preferred embodiments of the present invention have been disclosed in the present specification and drawings, and although specific terms have been used, they have been used only in a general sense to easily describe the technical contents of the present invention and to facilitate understanding of the invention , And are not intended to limit the scope of the present invention.
