The figure which shows the external appearance of the signboard 1. FIG. The figure which shows the electrical structure of the signboard 1. FIG. The front view of the test | inspection apparatus 20. FIG. The figure which shows the electrical constitution of the inspection apparatus 20.

An example for carrying out the present invention will be described.
FIG. 1 is a view showing the appearance of the signboard 1. (A) is a front view, (b) is a right side view. The signboard 1 includes a display board 2 and legs that support the display board 2.

  FIG. 2 is a diagram showing an electrical configuration of the signboard 1. The signboard is 1, a display plate 2, a diaphragm 4, a control unit 5, a storage unit 6, a thermometer 7, a WBGT measuring device 8, a human sensor 9, a display plate driving circuit 10, a diaphragm driving circuit 11, and a vibration generating unit 12. Is provided. The display board 2 is, for example, twist ball electronic paper. Sound is generated when the vibration generating unit 12 vibrates part or all of the display panel 2. That is, the display panel 2 also has a function as the diaphragm 4 of the flat speaker. The vibration generating unit 12 is, for example, a piezoelectric element. That is, the display plate 2 is an example of a planar structure display unit, and the diaphragm 4 is an example of a planar structure audio output unit. The display unit and the audio output unit are provided on the same plane.

  The control unit 5 includes an arithmetic device such as a CPU (Central Processing Unit) and a storage device such as a ROM (Read Only Memory) and a RAM (Random Access Memory). The ROM stores firmware that describes the startup procedure of hardware and an OS (Operating System). The RAM is used for storing data when the CPU executes an operation.

  The storage unit 6 stores image data and audio data in advance. The image data is raster data representing a model of an image (see FIG. 1) displayed on the display board 2. In this image data, for example, 0 ° C. is set as an initial value of the temperature (“current temperature” in FIG. 1) and the heat index.

  The thermometer 7 measures the temperature and outputs the measured value to the control unit 5. The WBGT measuring device 8 measures a heat index (Wet Bulb Globe Temperature) and outputs the measured value to the control unit 5. The human sensor 9 detects the approach of a person using, for example, infrared rays or ultrasonic waves, and outputs the detection result to the control unit 5.

  The control unit 5 reads the image data from the storage unit 6 when any of the measurement values output from the thermometer 7 and the WBGT measuring device 8 is changed, and displays the latest temperature and heat index. Thus, the image data is rewritten and output to the display panel drive circuit 10. The display board driving circuit 10 outputs an electrical signal based on the image data output from the control unit 5 to the electrodes of the electronic paper constituting the display board 2. In the example of FIG. 1, 26 ° C. is displayed as the latest temperature (current temperature), and 23 ° C. is displayed as the latest heat index. Below the heat index, a heatstroke warning indicating a warning guide based on the heat index is displayed. There are four stages of heatstroke warnings: danger (31 ° C. or higher), strict alert (28 ° C. to 31 ° C.), alert (25 ° C. to 28 ° C.), and caution (21 ° C. to 25 ° C.).

  The sound data stored in the storage unit 6 is data representing the frequency and amplitude of vibration generated by the vibration generating unit 12, and stores sound data of a plurality of patterns according to the temperature and the heat index. . Specifically, for the air temperature, voice data indicating a voice “The current temperature is XX ° C.” is created in increments of 1 ° C. from −20 ° C. to 40 ° C., for example. 6 is stored. Similarly, with respect to the heat index, sound data indicating a sound “The heat index is OO ° C.” is created in increments of 1 ° C., and this sound data is stored in the storage unit 6. For heatstroke warnings, voice data indicating the voice of “heatstroke warning is XX” has been created at each stage of danger, strict warning, vigilance, and caution. This voice data is stored in the storage unit 6. It is remembered.

  The control unit 5 executes the following processing based on the detection result of the human sensor 9. Specifically, when the human sensor 9 detects the approach of the person, the control unit 5 reads out the voice data corresponding to the latest temperature, heat index, and heat stroke warning from the storage unit 6 and reads the diaphragm. Output to the drive circuit 11. The diaphragm driving circuit 11 outputs an electrical signal based on the audio data output from the control unit 5 to the vibration generating unit 12. The vibration generating unit 12 generates vibration according to the electric signal output from the diaphragm driving circuit 11, and the vibration is transmitted to the diaphragm 4 to generate sound. For example, when a person approaches the signboard 1 displaying the image shown in FIG. 1, a voice is generated saying, “The current temperature is 26 ° C. The heat index is 23 ° C. The heat stroke warning is caution”. .

<Modification>
The above embodiment may be modified as follows.
<Modification 1>
FIG. 3 is a front view of the inspection apparatus 20. The inspection device 20 includes a display board 2 and a mirror 21.
FIG. 4 is a diagram showing an electrical configuration of the inspection apparatus 20. The inspection device 20 includes a display plate 2, a diaphragm 4, a control unit 5, a storage unit 6, a human sensor 9, a display plate driving circuit 10, a diaphragm driving circuit 11, a vibration generating unit 12, and an imaging unit 22. In the following, parts different from the embodiment will be described.

  The storage unit 6 stores image data and audio data in advance. The image data is raster data representing a model of an image (see FIG. 3) displayed on the display board 2. This image data is image data representing an image illustrating equipment worn by a person. For example, in the case of a worker engaged in construction work, an image in which an outline of the upper body of a person and equipment such as a helmet, a vest with a reflector, and an ID card are arranged is displayed. The imaging unit 22 is a digital still camera, for example.

  The control unit 5 executes the following processing based on the detection result of the human sensor 9. Specifically, the worker stands toward the mirror 21 to confirm his / her equipment. Then, the human sensor 9 detects the approach of the worker. If the approach of the worker is detected, the imaging unit 22 captures the worker, generates image data, and outputs this image data to the control unit 5. The control unit 5 analyzes the image represented by the image data, and is compared with the image data stored in the storage unit 6 in advance, whether equipment such as a helmet, a vest with a reflector, or an ID card is attached. Determine whether or not. If there is equipment that is not installed, a notification that the equipment is not installed is displayed and sounded. For example, when the helmet is not worn, the helmet portion is blinked. In addition, a voice such as “Please wear a helmet” is output. That is, this configuration includes a mirror, a planar structure display unit, and a planar structure audio output unit on the same plane, and includes an image recognition unit that performs image recognition on a person in front of the mirror, It is an example of the inspection apparatus which judges the lack of the predetermined equipment about the person in front of the mirror based on the recognition result by the recognition means, and notifies the lacking equipment by the display means and the voice output means.

<Modification 2>
When the human sensor 9 detects the approach of a person, the heatstroke warning corresponding to the latest heat index may be highlighted and displayed. For example, when the heat stroke warning corresponding to the latest heat index is a caution, the caution portion may be blinked. Alternatively, only the caution part may be displayed without displaying the danger, strict warning, and warning parts.

<Modification 3>
The diaphragm 4 may generate sound having directivity. For example, voice with directivity may be generated so that only the person located in front of the signboard 1 can hear the voice.

<Modification 4>
The application program may be provided by being recorded on a computer-readable recording medium such as an optical recording medium or a semiconductor memory, and the program may be read from the recording medium and installed. In addition, this program may be provided through a telecommunication line.
