Abstract

(57) [Summary] [Purpose] The purpose is to sufficiently convey a message of danger prevention to people or vehicles passing by around the display. [Structure] When a detection device provided on the display detects an object to be detected, it displays it and outputs an arbitrarily used voice message to alert the pedestrian or passing vehicle to the danger by visual effects. It conveys the message to do.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a display device for transmitting and displaying a message to a person or a vehicle passing by around a display device.

[0002]

[Prior art]

 Conventionally, this type of display device unilaterally transmits and displays a message to a person passing by around the display device. Especially, a display device installed in a construction site or a parking lot facing the road, etc. Safety slogans, warning messages, and other messages are displayed on the regular display for relevant people and vehicles to enhance safety awareness.

[0003]

[Problems to be solved by the device]

 However, this type of display device attracts attention and raises safety awareness when initially installed in a construction site or a parking lot facing the road. However, there was a defect that lacked safety awareness. The present invention has been made to address such problems, and an object of the present invention is to provide a display device in which a message can be effectively transmitted to a person or a vehicle passing around the display device.

[0004]

[Means for solving the problem]

 In order to solve such a problem, the present invention should provide a display device for displaying a message, a detection device connected to the control unit of the display device for detecting the presence of an object to be detected, and the display device. When the detection device detects an object to be detected, the storage unit for storing a message and a timer for determining a display time provided in the control unit display the message stored in the storage unit on the display unit and display the message on the display unit. The feature is that the display is turned off or turned on by a timer.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an external front view of a display device according to an embodiment of the present invention. Reference numeral 1 is a display device body installed at a doorway of a construction site or a parking lot. Light emitting elements such as light emitting diodes are arranged in a matrix. A message consisting of characters, patterns, etc. is displayed on the arrayed display unit 2, and a control unit 3 described later is built in. Reference numeral 4 denotes a detection device such as an infrared sensor attached to the display device 1, which detects a person passing in a predetermined range or a vehicle existing in a predetermined direction from the detection device 4. Reference numeral 5 denotes a voice notification means attached to the display unit 1, which is formed so that a message synthesized in advance, for example, a safety slogan such as "Danger, please be careful" or "I will drive" can be output. Reference numeral 6 denotes a voice stop switch provided at an appropriate position of the display device 1 so that the user can arbitrarily stop the voice output by the voice notification means 5.

Next, FIG. 2 shows a block diagram of the control unit 3 built in the display device 1 and the input / output device connected to the control unit 3, and the control unit 3 uses the detection device 4 as a human input / output device. Alternatively, the input means 7 for inputting a message to be displayed on the display 2 when a vehicle is detected, the display 2, the detection device 4, the voice notification means 5 and the voice stop switch 6 are connected to each other. Further, the control unit 3 has a central processing unit 9 which is a control unit for processing and executing a program on the data bus 8, a storage unit 10 for storing the program, a storage unit 11 for storing a message, the input unit 7, and the detection unit 4. Display that outputs display data and control signals to the input / output units 12 and 13 of the voice notification unit 5 and the voice stop switch 6 and the drive circuit 14 that controls lighting / non-lighting of the light emitting elements arranged in the display 2. Controllers 15 are respectively connected to control the input / output devices 2, 4, 5, 6, 7. Further, the detection device 4 may be configured so as to detect an object to be detected such as a person or a vehicle, and is appropriately selected depending on the usage condition such as the pressure sensitive switch S laid on the road surface.

Next, the operation of the display device will be described. Normally, the central processing unit 9 stores the message in the storage means 11 and waits for detection of the detected object of the detection device 4. When an object to be detected such as a person or a vehicle is present around the display device 2 and the detection device 4 detects it, the message stored in the storage means 11 is displayed on the display device 2 and an optional voice notification means is provided. A voice message is output in accordance with No. 5 to notify the passers-by who are users and vehicle drivers of accident prevention through visual and auditory effects. The central processing unit 9 holds the detection state of the detection device 4 for a certain period of time by the timer T, displays the message on the display device 2, turns off the light, and then waits for the detection device 4 to detect the detected object again.

When the voice output by the voice notification means 5 causes noise interference at night, the voice stop switch 6 can be turned on to stop the voice output. Further, instead of the voice stop switch 6, if the presence or absence of voice output and the time zone thereof can be set via the input means 7, the usability is improved.

In this way, the display device 1 displays a message when the detection device 4 detects the presence of a person or a vehicle around the detection device 4 of the display device 2 to call attention, and the voice notification means 5 used as necessary. It is also possible to output a voice message via. Therefore, when passing around a dangerous place such as the work site or the entrance of a parking lot, a warning display is displayed by voice notification and display notification, so that awareness is raised each time and as a result, safety awareness increases and accident prevention can be achieved. .

[Effect of device]

 The present invention is configured as described above, and stores a display device that displays a message, a detection device that is connected to the control unit of the display device and that detects the presence of an object to be detected, and a message that should be displayed on the display device. When the detection device detects an object to be detected, the storage device includes a storage unit and a timer for determining a display time, and the message stored in the storage unit is displayed on the display unit and the display of the display unit is displayed. The feature of turning off or turning on the light by a timer is set, so that when entering and exiting a car at a parking lot or at a construction site, a vehicle can be set in and out for an appropriate period of time during which the car enters and exits. The display can be displayed each time to call attention, and the display can be turned off or turned on after a certain period of time. Accidents can be prevented by the familiar in comparison with the will to perform the display at all times can be warning Te. Further, if the detection device is appropriately set according to the object to be detected, a reliable display operation can be performed only on the object, and the reliability can be improved.
