Description

  The present invention relates to a portable pointing / calling confirmation device for prompting an operator to execute pointing / calling and confirming the execution.

  In general, in order to ensure work safety and work quality at construction sites, etc., danger prediction is performed by individual workers pointing and calling before starting work, or by using meetings held during morning meetings or lunch. Along with the activities, all workers are pointing and calling to alert and check the points of caution. With regard to work safety, for example, the Ministry of Health, Labor and Welfare has reported that 77% of the results are the result of human unsafe conditions and unsafe behavior.

  In particular, unsafe behavior is affected by the level of human consciousness. As a document on the consciousness level, for example, “5 levels of consciousness level” described in Non-Patent Document 1 is known. Table 1 is a table of “5 levels of consciousness level” described in Non-Patent Document 1, and shows the state of consciousness at each level and the level of attention and judgment associated therewith. In this table, it is desirable to be active in a clear state of consciousness, such as the level of consciousness in Stage III.

  On the other hand, as described above, pointing and calling by an individual worker before starting work is effective for improving the worker's level of consciousness at the time of doing so. However, since the level of consciousness decreases unconsciously over time, it is difficult to maintain a high level of consciousness in the third stage even after the work starts. As a countermeasure, the following guidance is given to workers.

(1) Before work, pay attention to the order and arrangement of things, and perform hazard prediction.
(2) In order to prevent sleepiness, perform gymnastics during breaks.
(3) When working, workers talk to each other.
(4) If you think your friend is in a strange state, help each other.
(5) Point out dangerous tasks and important matters.

  However, there are many cases where the work is carried out by one person, and the measures shown in the items (3) to (5) are difficult to be executed under such a situation. On the other hand, even when a work is performed by a plurality of people, it is difficult to say that the particularly important item (5) is pointed and called, and it is strongly desired to solve the problem. Therefore, the present invention has an object to solve such problems, and in particular, to provide a portable pointing / calling confirmation device that prompts the worker to point appropriately and confirms its execution over the entire work time. Objective.

  The portable pointing and calling confirmation device of the present invention that solves the above-mentioned problem is that an audio signal generating unit that outputs a predetermined audio signal when an activation signal is input, a microphone, and a recording signal are continued. An audio recorder for recording an audio signal output from the microphone for a certain period, a speaker to which an audio signal output from the audio signal generator or an audio signal output from the audio recorder is input, a playback switch, and a control Department. The controller is configured to output a start signal to the audio signal generator at a preset time and simultaneously output a recording signal to the audio recorder for a preset period. When the playback switch is turned on, the recorded audio signal is output to the speaker (including an earphone, the same applies hereinafter) (claim 1).

  In the above apparatus, a response determination unit that determines whether or not there is an audio signal output from the microphone only during a period in which the response signal continues, and the response determination unit has confirmed the presence of the audio signal output from the microphone A counter for counting the number of times and a display unit for displaying the count number of the counter may be provided, and the control unit may be configured to output the response signal during the output period of the recording signal.

  In the portable pointing / calling confirmation apparatus of the present invention described in claim 1, for example, a predetermined voice such as “please point and call” is stored in the voice signal generation unit, and the control unit The activation signal is output to the audio signal generation unit every predetermined time from the start, and thereby the audio signal is output as audio from the speaker to prompt the operator to point and call.

  Further, the control unit outputs a recording signal to the voice recorder unit simultaneously with the activation signal, and the recording signal continues for a preset period. When the operator performs pointing and calling while wearing the microphone during the continuation period, the voice is transmitted from the microphone as a voice signal to the voice recorder unit and recorded. Therefore, the worker is encouraged to confirm the pointing and calling by speaking himself at a preset time, and it will be executed accordingly, so the worker's consciousness level during the work period is set appropriately. Can be maintained. The microphone and the speaker may be separate, or may be an integrated microphone and earphone.

  In this way, the operator can avoid an inadvertent state, so that an accident can be prevented from occurring during the work. In addition, since voice output and voice recording operations are automatically executed by signals from the control unit, the operator does not need to perform any special operation on the apparatus, and there is no trouble or influence on the work. Furthermore, the recorded content can be played back from the speaker by turning on the playback switch. For example, the supervisor who performs the work management can play back and confirm the execution of the operator's pointing and calling. Guidance can be performed appropriately.

  In the portable pointing and calling confirmation device, as described in claim 2, a response determination unit that determines the presence or absence of an audio signal output from the microphone only during a period in which the response signal continues, and a response determination A counter that counts the number of times the unit confirms the presence of the audio signal output from the microphone, and a display unit that displays the count number of the counter, and the control unit also outputs the response signal during the output period of the recording signal Can be configured to.

  With this configuration, for example, the supervisor who performs work management reproduces the voice recorded in the voice recorder unit, and even if the details of the voice content are not confirmed, only the count number displayed on the display unit is instantaneously generated. If confirmed, it is possible to confirm the extent of the operator's pointing and calling. Therefore, even if there are a large number of subjects to be supervised, it is possible to quickly confirm the execution of the many pointing and calling.

Next, the best mode for carrying out the present invention will be described with reference to the drawings.
(First embodiment)
FIG. 1 is a block diagram for explaining a first embodiment of a portable pointing and calling confirmation device according to the present invention. The pointing and calling confirmation device 1 is housed in a housing such as a portable case, and includes an audio signal generator 2, a microphone 3, an audio recorder 4, a speaker 5, a playback switch 6, and a controller 7. Further, in order to supply power to these devices, a power supply unit 8 made of a rechargeable battery is provided. The speaker 5 is attached to the surface of the housing portion, and the microphone 3 can be operated outside the housing portion with or without a cord. For example, the microphone 3 can be housed in an operator's breast pocket or a headphone like a headphone. The shape can be attached to.

  The audio signal utterance unit 2 can be preferably composed of a digital recording device, and stores a predetermined audio such as “Please point and call”. The audio signal utterance unit 2 is activated every time an activation signal is input from the control unit 7 and outputs the audio signal to the speaker 5 with the recorded content as one phrase. When the output of the recorded contents is completed, the process waits until the next activation signal is input.

  The audio recorder 4 is also preferably composed of a digital recording device, and can record an audio signal input from the microphone 3 via a cable or the like only during a period when the recording signal is output from the control unit 7. The content recorded in the audio recorder unit 4 is output to the speaker 5 when the reproduction switch 6 is turned on. When the playback switch 6 is configured by a push button, the voice recorder unit 4 is configured to transmit the entire recorded content to the speaker 5 as one output after receiving the ON signal of the playback switch 6. . Further, when the playback switch 6 is configured by an ON-OFF switching switch, the audio recorder unit 4 is configured to transmit the recorded content to the speaker 5 only during a period when the ON signal of the playback switch 6 is received.

  The control unit 7 can be constituted by a timer, for example, and outputs a start signal to the audio signal generation unit at a preset time and simultaneously outputs a recording signal to the audio recorder unit for a preset period. Composed. For example, the control unit 7 is set to output a start signal at intervals of 15 minutes and output a recording signal for 20 seconds.

  The control unit 7 can also be configured by a programmable device such as a microcomputer device. In that case, the output timing and interval of each control signal are programmed in advance and stored in the storage unit. When the control unit 7 is configured by a microcomputer device, the audio signal generation unit 2 and the audio recorder unit 4 can also be configured by being incorporated in the microcomputer device.

  FIG. 2 is a time chart for explaining the operation timing of the pointing and calling confirmation device 1 of FIG. FIG. 2 shows a case where the first control signal is output from the control unit 7 and a case where the nth control signal is output as a representative example. Control signals are repeatedly output at the same interval.

  First, the first case will be described as an example. When an activation signal is output from the control unit 7, the audio signal generation unit 2 is activated and an audio signal is output to the speaker 5. The audio signal output period of the audio signal generator 2 is proportional to the recording time of the audio signal, but is usually about several seconds to 15 seconds. Simultaneously with the output of the start signal from the control unit 7, a recording signal is output to the voice recorder unit 4 for a predetermined period, whereby the voice recorder unit 4 is in a recordable state.

  The duration of the recording signal is set longer than the audio signal output period of the audio signal generator 2 in consideration of the audio input margin by the microphone 3. For example, when the output period of the audio signal is about 15 seconds as described above, it is desirable to set the duration period to about 20 to 30 seconds.

  In the case of the first time, as indicated by the solid line, the voice of pointing and calling from the microphone 3 is input to the voice recorder unit 4. The audio recorder unit 4 records the audio signal, and when the playback switch 6 is turned on later, the recorded content is reproduced from the speaker 5 as audio.

  On the other hand, in the case of the n-th time, as indicated by the dotted line, no voice of pointing and calling is input. In that case, no sound is recorded there even though the sound recorder unit 4 is in a recordable state, and therefore no sound is reproduced from the speaker 5 even if the reproduction switch 6 is turned on later.

(Second Embodiment)
FIG. 3 is a block diagram for explaining a second embodiment of the portable pointing and calling confirmation device according to the present invention. This embodiment is different from the example of FIG. 1 in that a response determination unit 9, a counter 10, and a display unit 11 are added, and the rest is configured in the same manner as the example of FIG. Therefore, the same parts as those in FIG.

  The response discriminating unit 9 discriminates the presence / absence of an audio signal from the microphone 3, and during the period in which the response signal from the control unit 7 continues, an audio signal having a preset signal level or higher is received for a predetermined period (for example, 3 seconds). As described above, when it is input, it is determined and the ON signal is output to the counter 10 only once. Therefore, the counter 10 is counted only once during the period when the response signal continues, even if an audio signal or noise of a level more than the set value is input several times.

  For example, if the number of responses of the worker corresponding to the number of times the pointing and calling command is output from the start to the end of the work is counted by the counter 10, it means that the response is 100%. Is displayed on the display unit 11 configured as follows. Note that the count recorded contents of the counter 10 can be reset as appropriate.

  FIG. 4 is a time chart for explaining the operation timing of the pointing and calling confirmation device 1 of FIG. FIG. 4 is different from FIG. 2 only in the response signal and the count of the counter 10, and the rest is the same. A response signal is output to the response determination unit 9 at the same timing when the activation signal and the recording signal are output from the control unit 7. As described above, the response determination unit 9 can determine whether or not there is a response from the audio signal from the microphone 3 only during the period in which the response signal continues.

  In the example of FIG. 4, in the first time, there is a response by the audio signal from the microphone 3, the response determination unit 9 determines that and outputs an ON signal to the counter 10, and the counter 10 counts once. Indicates the situation. However, in the case of the nth time, since there is no response by the audio signal from the microphone 3, the response determination unit 9 determines that and does not output an ON signal to the counter 10, and the counter 10 does not count. . Therefore, if the count is confirmed after the work is completed, it is possible to know the response status of pointing and calling by a specific worker on that day.

  In the above-described embodiment, specific sound is recorded in advance in the sound signal generation unit 2, but not limited to such sound content, simple sound, music, etc. previously determined with an operator may be recorded. Further, as a measure for preventing habituation, a plurality of audio signals can be recorded sequentially or in a random order. Furthermore, as another method for preventing habituation, the output timing of the activation signal of the control unit 7 can be set at random time intervals within a preset period.

  When the main part of the portable pointing / calling confirmation apparatus according to the present invention is composed of a microcomputer device, not only the pointing / calling confirmation part but also a mobile phone function or other PDA (portable information processing terminal device). Or the like can be added as a component of the microcomputer device.

  INDUSTRIAL APPLICABILITY The portable pointing and calling confirmation device of the present invention can be used as a device for prompting an operator to execute pointing and calling during work and checking the execution status.
