Description

A ELECTRIC DISPLAY OF HEALTH AND USAGE MONITORING PROTECTION SYSTEM}

Generally speaking, electric signboard is a plate-shaped device that informs information by arranging numerous light bulbs or LED element lamps and blinking them to display characters or pictures, and is applied indoors and outdoors.

As described above, it is a device that performs an electronic bulletin board function that is utilized by inputting data to the electronic sign controller by wired or wireless methods in order to display characters or pictures on the signboard. This device has the advantage of being able to display a lot of data sequentially or temporarily, but when some functions are stopped due to its own defect, it reaches a useless state in which information cannot be displayed properly.

Therefore, it is necessary to periodically check whether or not the electric signboard is operating normally, but the general electric signboard currently in operation does not have a self-status monitoring or failure prevention function.

The present invention relates to the manufacture of an electric sign, and more particularly, to a system that provides immediate assistance in maintenance work by implementing a state monitoring and failure prevention during operation of an electric sign, and specifying a failure area in case of failure.

FIG. 1 shows a flow of a conventional electronic signboard manufacturing process. Referring to FIG. 1 below, referring to FIG. 1, a general electronic signboard manufacturing is described. First, the signboard is designed, and main and subsidiary materials necessary for the production are prepared, which are arranged and assembled as shown in FIG. , After interconnecting and combining electric wires and data cables, the display information is input to the controller (controller) and displayed.

The main components of electronic signboard manufacturing consist of ① signboard module 201, ② power supply unit 202, ③ controller 203, ④ frame 200, ⑤ electric wire and data cable 204, ⑥ screws, and other subsidiary materials. . The electronic signage manufactured in this way is displayed on the electronic signage screen in the same operation flow as in FIG. 4A. At this time, if even one of the constituent parts operates normally, the electric signboard cannot perform the final purpose of the display.

As can be seen from the above description, a general electric signboard currently being manufactured does not have a device capable of monitoring the condition of each major component or signs of failure. This has a problem in that the loss in the operation side of the signboard becomes significant, considering the problem of not being able to grasp which zone, which part, and what fault at all even in the diagnosis of the faulty part for repair in the event of a signboard failure.

Particularly, most of the internal parts of the electric signboard are made of semiconductor devices, and have a characteristic that causes malfunction when the temperature rises above a certain temperature (eg, 70℃). As a countermeasure for this problem, ventilation is attempted using a ventilation fan (FAN), but this is a constant temperature and humidity function, and when a fan (FAN) fails or abnormal high temperature occurs, a semiconductor device malfunction occurs. Neglect of such an increase in temperature has a serious problem that can damage the entire electric display board.

The present invention was created under the technical background for solving these conventional problems.

Currently, some products are operated by combining an image monitoring system to monitor the operation of an electric signboard, but this is a function to monitor whether the displayed text or picture is normally displayed, and is for data display verification. As in the present invention, it is not possible to perform various condition monitoring such as major parts of an electric sign. That is, it is completely different from the present invention.

The technical problem to be achieved by the present invention is to solve the problem of not always detecting and preventing a failure of an electric sign during operation, and it is an object of the present invention to provide a failure prevention system for monitoring the condition of an electric sign to achieve this technical problem. .

The present invention detects a change in the operating environment of an electric signboard, aims to improve an unsuitable environment, and cuts off the power in advance when the temperature rises in order to prevent a failure due to an unsuitable environmental effect, or increases the humidity and outputs a DC power supply. In the event of a power abnormality, a signal is transmitted to prepare for an error in the signboard device, and even in the event of a failure, it helps repair by providing an easy diagnosis and grasp of whether the power supply part or the signboard (display) module part is faulty.

The present invention configured as described above protects the electronic signboard internal device semiconductor from temperature rise to prevent failure and damage to the signboard, and the signboard component is a device that is densely constructed and attached as an element vulnerable to humidity. By interlocking ventilation and stopping the ventilation fan (FAN), it prevents failure in advance, and by constantly monitoring the constant voltage output of the internal DC power supply (SMPS), it prevents the spread of failure in case of instability. There is an advantage in that the life span of the electronic board can be extended and various losses can be reduced by preventing such failures.

However, the embodiments according to the present invention may be modified in various forms, and the scope of the present invention should not be construed as being limited to the embodiments described below. Embodiments of the present invention are provided to more completely describe the present invention to those with average knowledge in the art.

A schematic internal configuration circuit diagram of a condition monitoring failure prevention system electric signboard, FIG. 6 is a diagram showing a connection circuit diagram of a condition monitoring failure prevention system electric signage detection unit (A) and a display unit (B) according to an embodiment of the present invention. Hereinafter, state monitoring and failure prevention according to an embodiment of the present invention will be described in detail with reference to FIGS. 3 to 6. Meanwhile, in the description of the present invention, a general electric sign is described, but the present invention is not limited thereto.

3 is a path through which main components inside the conventional display board are interconnected to supply power. ① Power AC (AC 220V) input, ② Power supply DC (DC5V) output, ③ Controller 203, ④ Display board module 201 ) Is connected and supplied by wire. Here, data input is transmitted to the controller by USB terminal, RJ45 terminal, and other wired or wireless methods, and connected serially and in parallel to each display module using a data cable from the controller.

FIG. 4 is a flow chart showing the operation flow chart of the conventional electronic display board A and the state monitoring failure prevention system electronic display board B according to an embodiment of the present invention, as described above, and will be described based on FIG. 4 (B). ① Power control and temperature detection controller (400), ② AC (AC 220V) input (401), ② Power supply DC (DC5V) output (402), ③ DC power monitoring detector and relay (403), ④ Internal humidity monitoring The detector and relay 404, ⑤ display data reception 407, and ⑥ display module 408 display characters or pictures. At this time, as can be seen from the comparison with Fig. 4 (A), the step of monitoring and detecting temperature, DC power supply, and humidity is included. That is, when the ① power input temperature detection controller 400 is operated, the input power is cut off with a switch, ③ when the DC power monitoring detector and relay 403 are operated, an alarm signal is transmitted, and ④ the internal humidity monitoring detector and the relay ( 404) In operation, it is used to transmit an alarm signal and start a ventilation fan (FAN).

In other words, a temperature detection controller is attached to the main power line that applies the input AC (AC220V) power and is input to the internal DC power supply (SMPS) through a temperature detection controller that cuts off the main power when it is detected above a certain temperature of the set value. A controller (controller) applied from the DC power supply (SMPS) output terminal and a voltage detector that constantly monitors the direct current (DC5V) supplied to the electro-optical (display) module, and transmits a signal in the event of a deviation from a certain range. Are interconnected. At this time, a humidity detector for detecting the humidity of the space inside the electric signboard is also provided so that a humidity increase signal is transmitted even when a humidity exceeding a certain value is detected.

FIG. 5 is a continuing description of the schematic internal configuration circuit diagram of an electronic display board for a condition monitoring failure prevention system according to an embodiment of the present invention. Unlike a conventional electronic display board, a component capable of monitoring internal temperature, humidity, and DC power is added first. The circuit is configured separately by combining it with.

The temperature detection controller has a function of varying the set temperature, and has two or more contacts and must be used in conjunction with a switch, and the humidity monitoring detector has a signal transmission contact in conjunction with an auxiliary relay, and the internal DC power monitoring and detection uses a relay. When the voltage is out of the maintenance range, a contact point for outputting an alarm signal must be provided.

The three components separately provided in this way form a detection unit 504 inside the electric signboard in which the respective components are assembled, and the display unit 505 is located separately in a portion for collecting and displaying signals transmitted from the detection unit. The status display unit 505 is provided with an access terminal for displaying each detection by lighting when temperature abnormality, lighting when humidity abnormality, and lighting when internal DC power abnormality, and transmitting the humidity, temperature, and power abnormality status to the outside. It is possible to monitor the condition and prevent failure through an application circuit as shown in FIG. 6.

6 (A) and (B) are diagrams showing the wiring circuit diagram of the condition monitoring and failure prevention system electronic board detection unit (A) and the display unit (B) according to an embodiment of the present invention. As a result, it is explained that each detector is specifically utilized.

6 shows the electrical circuit of the system of the present invention in addition to the above. It is applied according to the signal received from the state detection unit 504 and is applied to the electric sign system. The temperature detection controller itself automatically cuts off the main power supply line and Lunge. The signal (contact) detected from the remaining monitoring detectors activates the built-in auxiliary relay and turns on the lamp indicating the status of each detector. At this time, the auxiliary relay operation contact is used to transmit the state to the outside, and in the case of humidity, it is applied and used to start a ventilation fan (FAN). In this way, the lamps lit on the display are manufactured so that they can be recognized from the outside of the electric signboard and are used in practical use.

In the present invention, the status monitoring failure prevention system display board can be confirmed by normal display of the display board screen in the normal operating state of the display board, and some components can be detected and monitored by the status monitoring failure system in case of abnormality.

Meanwhile, in the above description of the present invention, specific embodiments have been described, but various embodiments may be implemented without departing from the scope of the present invention. In particular, in the embodiment of the present invention, a contact point has been described when using a monitoring detector, but condition monitoring and failure prevention applied to various devices including mechanical and electronic types are equally applicable. Therefore, the scope of the invention should not be determined by the described embodiments, but should be determined by the claims.
