Abstract

A wireless network-based portable wireless flashing light system is based on a wireless network-based portable wireless flashing light. The wireless network-based portable wireless flashing light includes a wireless communication module, a display unit, an emergency alarm unit, and a control unit. The wireless communication module transmits and receives a wireless signal to and from an outside. The display unit displays predetermined information. The emergency alarm unit provides notification of an emergency. The control unit extracts status information about manufacturing machines from the signal received from the wireless communication module, displays information about a manufacturing machine in which an abnormality occurs on the display unit based on the status information, and operates the emergency alarm unit.

Claims

1. A wireless network-based portable wireless flashing light, comprising:

a wireless communication module for transmitting and receiving a wireless signal to and from an outside;

a display unit for displaying predetermined information;

an emergency alarm unit for providing notification of an emergency; and

a control unit for extracting status information about manufacturing machines from the signal received from the wireless communication module, displaying information about a manufacturing machine in which an abnormality occurs on the display unit based on the status information, and operating the emergency alarm unit;

wherein the wireless network-based portable wireless flashing light is operated by the control unit according to the wireless signal received from the outside.

2. The wireless network-based portable wireless flashing light as set forth in claim 1, wherein the emergency alarm unit comprises at least one of an alarm sound generation unit and a vibration generation unit, and the control unit operates the alarm sound generation unit or the vibration generation unit when the abnormality occurs in the manufacturing machine.

3. The wireless network-based portable wireless flashing light as set forth in claim 1, further comprising a light emission unit having one or more light-emitting elements;

wherein the light-emitting elements are assigned to respective manufacturing machines, and the control unit turns on a corresponding light-emitting element of the light emission unit when an abnormality occurs in a specific manufacturing machine.

4. A wireless network-based portable wireless flashing light system, comprising:

a portable wireless flashing light comprising a first wireless communication module, an emergency alarm unit and a control unit;

one or more status information transmission devices for receiving status information about manufacturing machines of a manufacturing line from the manufacturing machines, and transmitting the input status information to an outside through second wireless communication modules respectively installed therein; and

one or more wireless routers for finding shortest routes between the portable wireless flashing light and the status information transmission devices, and transmitting the status information, received from the status information transmission devices, via the found shortest routes;

wherein the control unit of the portable wireless flashing light receives the status information from the wireless routers through the first wireless communication module, and operates the emergency alarm unit when an abnormality in a specific manufacturing machine is detected from the status information.

5. The wireless network-based portable wireless flashing light system as set forth in claim 4, wherein the portable wireless flashing light further comprises a display unit capable of displaying text or the like, and the control unit of the portable wireless flashing light displays information about a manufacturing machine in which an abnormality occurs on the display unit when the abnormality in the manufacturing machine is detected from the status information.

6. The wireless network-based portable wireless flashing light system as set forth in claim 4, wherein the portable wireless flashing light further comprises an input switch unit which can be operated by a user, and the control unit stops operation of the emergency alarm unit when the input switch is operated.
