Referring to the operation and effects of the present invention configured as described above based on Figure 3 as follows.

In order to remotely control the signboard, first, when the signboard power is initialized, the central processing unit 20 on the signboard reads the operating programs of the internal memory ROM 24 and the RAM 23 and initializes the screen according to the control of the corresponding program. The display data is displayed on the electronic display module. In this state, the desired text such as letters and numbers can be input through the input unit of the portable remote controller 1 or a computer (not shown). Set various display modes such as reduction and reverse. Such an input command is transmitted wirelessly or by infrared rays to a transceiver on the side of an electronic panel through a serial component of a converter, amplification unit, and a transceiver unit under the control of the central processing unit 20. The process of controlling each of the desired phrases is the same as usual.

The present invention is realized as shown in FIG. 3 when the operation of the input unit 16 including the test key command of the portable remote controller 1 is input in addition to the above function, and the test key input command is performed in the state of initializing (S1). When applied (S2) the central processing unit 10 decodes the test command and outputs the signal corresponding to the input command of the converter 14 and the amplifier 13 by wireless or infrared through the transceiver 12 ( S3) At this time, it is natural to read the matrix type data stored in advance in the memory 15 and display them on the LCD 11.

When the data received in step S4 is interpreted and recognized as a test command, the central processing unit 20 switches the test mode of the internal program. The test mode recognizes each display element as a sequential lighting operation and sequentially controls (S5). ).

For example, the display element of a1 is turned on (S6), the current change amount detected from the current detection sensor 25 according to the lighting is turned on, and stored in the memory for determining whether there is an error (S8) (S9) (S10), and the display element of the b1 is turned on (S61). In this case, the series of processes such as detecting the amount of current change from the current sensor as it lights up and storing it in the memory to determine whether there is an error are continued until the matrix coordinate end point is reached.

In the state of temporarily storing the corresponding data in step S10, the central processing unit 20 recognizes the end S63, reads out the stored data, and transmits the stored data to the remote controller 1, which is the same as the above-described process.

Compare the data being sent in step S10 to the LCD 11 window in which the matrix-type data stored in advance in the memory is read out in step S3 and displayed in the corresponding coordinates. Control the name to be displayed.

On the other hand, Figure 4 is another control configuration of the electronic sign plate to which the present invention is applied, Figure 5 is a control flowchart of FIG.

4 is divided into two components: firstly, an electronic display device 210 including a display module installed on the outside, and an anti-theft alarm device 100 installed therein to wirelessly connect the electronic display device 210 with each other. Can be.

Specifically, as illustrated in FIG. 1, the burglar alarm apparatus 100 includes sensors 110, 120, and 130, a transmitter 140, a central processing unit 100, an alarm unit 150, and a communication unit 160. The signboard device 200 includes a signboard display module 250, a driver 240, a central processing unit 200 ′, a receiver 210, and a backup battery 260.

The code 110 of the burglar alarm device is a sensor which is installed at a certain internal location and includes a surveillance camera for monitoring the intruder's movement, an infrared sensor for detecting the body heat of the intruder, and 100 is the overall control of the burglar alarm device. Determining whether or not intrusion using the data applied from the sensors, but if it is confirmed that the intrusion is a central processing unit for outputting the stolen fact control signal, 150 is an external sound by a predetermined warning sound by the output signal of the central processing unit (100) It is an alarm to inform.

In addition, 140 is a transmission unit for transmitting the intrusion signal to the electronic display board wirelessly by the output signal of the central processing unit, the normal signal other than the intrusion signal is also transmitted every predetermined period. It is obvious that the code 160 is provided with a communication unit for automatically forming a call path to an external line, that is, an intrusion detection fact in a police box or other set place.

Reference numeral 210 is a receiver for wirelessly inputting an intrusion detection signal applied by the burglar alarm apparatus 100, and the central processing unit of 200 'transmits and displays display data of input characters and numbers to the display module for controlling display. Of course, there is included a RAM (RAM) 220 and a ROM (ROM) 230 configured as a memory for storing the program for controlling the electronic signboard, theft message data.

Reference numeral 240 is a driving unit for driving the display module display board by a control signal of the central processing unit 200 ', and the display module for the display board is a computer (input means) for creating and transmitting texts such as numbers and letters. In addition, the display control unit 250, which receives the data transmitted by the control of the central processing unit 200 'for controlling the electronic display board, stores the received data and supplies the data to the display unit 252, this display A display unit 252 for receiving data from the controller 250 and displaying the data to the display device (light emitting diode) is included.

Here, the back-up battery 260 is provided separately in the electronic device 200, which is operated in the power-off condition by the intruder, and the periodic normal signal blocking and power-off condition of the burglar alarm device 100 (intruder communication line In the case of simultaneous blocking and power line cutoff), it is preferable to include a series of operation procedures that read out the intrusion fact message recorded in the memory of the electronic display apparatus 200 and express the corresponding contents directly on the display module.

Referring to the operation and effects of the present invention configured as described above based on Figure 5 as follows.

In order to control the electronic board, first, when the power of the electronic board is initialized, the central processing unit 200 'on the electronic board side reads the operating programs of the internal memory ROM 230 and the RAM 220 and initializes the screen according to the control of the corresponding program. The display data is displayed on the electronic display module, and in this state, the desired text such as letters and numbers can be input through the input unit of the computer 300, but various display modes such as screen inversion, zoom in, zoom out, and reverse of the text as needed. The process of demonstrating the desired phrase by controlling the display elements of the corresponding display module by setting the

The present invention can realize the configuration associated with the anti-theft device 100 is installed in addition to the above function as shown in Fig. 5 bar in the initializing state (S1 ') the internal setting of the anti-theft device 100 If the security mode (S2 ') is not set, the display proceeds to the normal display operation. If the security mode is set in the step, the operation of the display board and the anti-theft device may be performed by modifying or editing the intrusion fact display phrase. The work for establishing the linkage is set (S4 ') (S5') (S6 ').

The detection step S7 'proceeds in the state of the above-mentioned linkage work, and the detection step S7' includes the opening and closing of the doorway, monitoring the intruder's movement, and detecting the heat dissipation of the intruder. If not in the normal state (S8 ') the central processing unit 100 continuously transmits the normal signal through the transmitter 140 every predetermined period.

If an intrusion is detected from the sensors 110, 120 and 130 that are not in the normal state in step S8 ', the central processing unit 100 immediately controls the alarm unit 150 and the call unit 160, which generate an alarm sound. In addition to realizing the operation of calling to a place previously connected to the outside and at the same time, the transmission of the intrusion signal through the transmitter 140 at the same time (S9 '). Accordingly, the receiver 210 receives the intrusion signal and transmits the intrusion signal to the central processing unit 200 '. At this time, the central processing unit 200' reads the intrusion fact data into the memory and displays the intrusion fact data on the display unit 252 of the display module. By controlling the phrase to be displayed, the intrusion is directly exposed to the outside (S10 ') (S11') (S12 ').

On the other hand, in case that the intrusion fact is not known through the operation such as cutting the external connection communication line or cutting off the power line of the burglar alarm device, the periodic signal is not transmitted (for a certain time) and the power is cut off for a certain time. (S14 ') (S15') (It is natural that the display panel device is continuously powered by the backup battery.) The central processing unit 200 'of the display panel device 200 determines that the memory is stolen and Read out from the control unit so that the phrase is displayed on the display unit 252 of the display module to directly expose the intrusion facts to the outside.

As described above, the present invention sequentially diagnoses the status of the LEDs arranged in a matrix form, but transmits the results to a portable remote control (remote control) located at a remote location. Since the display is quick, the product quality is improved by the addition of the function, and the self-diagnosis confirmation is made easier with the naked eye.

In addition, by interlinking the electronic sign installed on the outside and the anti-theft device installed on the inside, by using the control signal of the anti-theft alarm system to express the intrusion of theft on the electronic sign, not only strengthens the theft alarm function, but also by illegal intruders It is a plan that can effectively cope with the alarm disabling condition caused by the removal of the burglar alarm device (disconnecting the communication line, shutting down the power supply).
