  Hereinafter, an embodiment will be described with reference to the drawings. As shown in FIG. 1, the safety confirmation system 1 is for confirming the safety of a worker who performs work in a spark plug production facility. Each worker has a plurality of worker terminals 2, A host computer 3 that is a computer that can wirelessly communicate with the worker terminal 2 via a wireless LAN router or the like, and a wireless communication that can be wirelessly communicated with the host computer 3 via the wireless LAN router or the like. And a terminal 4.

  The worker terminal 2 is a small terminal that has predetermined sound generation means and vibration means and can be carried by the worker, and includes a confirmation reply information transmission unit 21 and a suspension request information transmission unit 22. As shown in FIG. 3, the worker terminal 2 includes a touch panel type input unit 23. The input unit 23 includes an information display area 231, a confirmation operation area 232, and a pause request operation area. 233.

  The information display area 231 is an area for displaying information according to information transmitted from the host computer 3. When confirmation request information described later is received from the host computer 3, information indicating that the confirmation request information has been received. (For example, “Confirming worker status”) is displayed. In the present embodiment, when the confirmation request information is received, a predetermined sound is emitted from the sounding means together with the display of information in the information display area 231. Further, the operator terminal 2 vibrates by the vibration means. Is configured to do. As a result, the operator is more reliably notified that the confirmation request information has been received.

  In addition, when the operator touches the confirmation operation area 232 (that is, when an input to the input unit 23 is performed), the confirmation reply information transmission unit 21 transmits confirmation reply information to the host computer 3. The That is, the operator responds to a response request (confirmation request information) from the host computer 3. The confirmation reply information includes information (for example, a terminal number assigned to each worker terminal 2) that can identify the transmitted worker terminal 2.

  In addition, when an operator or the like touches the suspension operation area 233, suspension request information is transmitted from the suspension request information transmission unit 22 to the host computer 3. The confirmation reply information transmission unit 21 and the temporary stop request information transmission unit 22 may be configured by the same transmission function component or may be configured by different transmission function components. The operation of the host computer 3 when receiving the suspension request information will be described later.

  The host computer 3 is configured by a CPU, a storage device, and the like. As shown in FIG. 1, the host computer 3 includes a confirmation request information transmission unit 31, a confirmation reply information reception unit 32, a reply confirmation unit 33, and a non-reply terminal identification unit 34. The non-reply confirmation information transmitting unit 35 and the non-reply terminal specific information transmitting unit 36 are provided.

  The confirmation request information transmission unit 31 transmits confirmation request information to each worker terminal 2 for each predetermined execution time (for example, one hour) set in advance.

  The confirmation reply information receiving unit 32 receives the confirmation reply information transmitted from each worker terminal 2.

  The reply confirmation unit 33 confirms the reply information to the confirmation reply information receiving unit 32 during a period from when the confirmation request information is transmitted by the confirmation request information transmission unit 31 until a preset confirmation time (for example, 5 minutes) elapses. Check if there is any received.

  The non-reply terminal specifying unit 34 is the terminal 2 for the worker who has not been confirmed to receive the confirmation reply information when the reply confirmation unit 33 does not confirm the receipt of the confirmation reply information to the confirmation reply information receiving unit 32. Specify the reply terminal. Specifically, based on information (for example, the terminal number) for identifying the worker terminal 2 included in the received confirmation reply information, an unreply terminal that has not been confirmed to receive confirmation reply information is identified.

  When the reply confirmation unit 33 does not confirm receipt of the confirmation reply information to the confirmation reply information receiving unit 32, the unreply confirmation information transmission unit 35, as shown in FIG. Non-reply confirmation information is transmitted to a terminal other than the unspecified terminal specified by the non-reply terminal specifying unit 34 in the terminal 2.

  When the reply confirmation unit 33 does not confirm receipt of the confirmation reply information to the confirmation reply information receiving unit 32, the unreply terminal specific information transmission unit 36 determines whether the non-reply terminal specific information transmission unit 36 Non-reply terminal specifying information (for example, the terminal number) is transmitted to a terminal other than the specific terminal. The confirmation request information transmission unit 31, the confirmation reply information reception unit 32, the reply confirmation unit 33, the non-reply terminal identification unit 34, the non-reply confirmation information transmission unit 35, and the non-reply terminal identification information transmission unit 36 are the same. It may be composed of functional parts or may be composed of different functional parts.

  Further, when the host computer 3 confirms reception of the confirmation reply information to the confirmation reply information receiving unit 32 in the reply confirmation unit 33 during a period excluding the period from when the confirmation request information is transmitted until the confirmation time elapses. The transmission of the confirmation request information to the worker terminal 2 that has transmitted the confirmation reply information is temporarily stopped. Then, after a predetermined waiting time set in advance (for example, the same time as the execution time) has elapsed since the suspension, transmission of confirmation request information to the worker terminal 2 that transmitted confirmation reply information is resumed. . That is, the worker voluntarily touches the confirmation operation area 232 of the input unit 23 before the worker terminal 2 receives the confirmation request information (before the confirmation request by the host computer 3), so that the host computer spontaneously 3 can respond.

  Further, in the present embodiment, when a spontaneous response is made from the worker, the host computer 3 sets the subsequent transmission timing of the confirmation request information as a timing based on the response time.

  More specifically, as shown in FIG. 4, confirmation request information is transmitted from the confirmation request information transmission unit 31, and the confirmation reply information is transmitted from the confirmation reply information transmission unit 21 until the confirmation time elapses from this transmission. When receiving (when a spontaneous response is not made), confirmation request information is transmitted from the confirmation request information transmitting unit 31 at each execution time.

  On the other hand, as shown in FIG. 5, when the confirmation reply information is received from the confirmation reply information transmission unit 21 in a period excluding the period from when the confirmation request information is transmitted until the confirmation time elapses (spontaneous response When the confirmation request information is transmitted), the transmission of the confirmation request information is paused, and the transmission of the confirmation request information is resumed after the waiting time has elapsed since the suspension. Therefore, the transmission timing of the confirmation request information is set to a timing based on the time when the confirmation reply information is received (at the time of the worker's spontaneous response).

  Further, when the host computer 3 receives the temporary stop request information from the manager terminal 2, the host computer 3 temporarily stops the transmission of the confirmation request information to the worker terminal 2. In the present embodiment, when the suspension request information is transmitted again from the manager terminal 2, the transmission of the confirmation request information to the worker terminal 2 is resumed.

  The manager terminal 4 has predetermined sound generation means and vibration means, and includes a display unit 41 made of liquid crystal or the like as shown in FIG. Further, when the non-reply confirmation information and the non-reply terminal identification information are received from the host computer 3, the display unit 41 indicates that there is a non-reply terminal (that is, that an abnormality has occurred) Information that can identify an unreplyed terminal based on the terminal identification information is displayed. In the present embodiment, when the manager terminal 4 receives the non-reply confirmation information, the manager terminal 4 displays the information on the display unit 41, emits a predetermined sound from its own sound generation means, and further vibrates itself. It is configured to vibrate itself by means. Thereby, it is more reliably notified to the administrator that there is a non-reply terminal.

  Furthermore, in this embodiment, when the terminal other than the non-reply terminal among the worker terminals 2 receives the non-reply confirmation information and the non-reply terminal specific information from the host computer 3, the input unit 23 does not reply. Information indicating that the terminal exists and information that can identify the non-reply terminal based on the non-reply terminal identification information are displayed.

  As described above in detail, according to the present embodiment, an administrator or the like can find an abnormality that has occurred in an operator at an early stage, and can quickly deal with the abnormality.

  Further, non-reply terminal identification information that can identify a non-reply terminal is transmitted to the terminals other than the unspecified terminal and the manager terminal 4 among the worker terminals 2. Therefore, an administrator or the like can quickly identify a worker who may have an abnormality from a plurality of workers. As a result, the abnormality that has occurred can be found even earlier.

  Further, in a period excluding a period from the transmission of the confirmation request information until a predetermined confirmation time elapses (so-called normal response period by the worker), the worker does not depend on the confirmation request from the host computer 3 side, It is possible to respond spontaneously, and transmission of the confirmation request information is suspended for a certain period after the spontaneous response. Thereby, for example, when performing work that requires concentration, it is possible to prevent the confirmation request information from being transmitted to the worker terminal 2 for a certain period of time by transmitting confirmation reply information in advance. As a result, work can be more concentrated and workability can be improved. In addition, an unexpected trouble occurs when an operator tries to input to the input unit 23 (send confirmation reply information) while performing a work requiring concentration as described above. It can prevent more reliably. As a result, worker safety can be ensured.

  In addition, the transmission of the confirmation request information when the voluntary response is made is temporarily stopped, and the transmission of the confirmation request information is automatically resumed after the waiting time has elapsed. Therefore, it is possible to prevent the transmission of the confirmation request information from being stopped.

  In addition, in this embodiment, transmission of the confirmation request information to the worker terminal 3 can be suspended by transmitting the suspension request information from the worker terminal 2 to the host computer 3. As a result, it is possible to temporarily prevent confirmation request information from being transmitted to the worker terminal 2 in the same manner as when the worker makes a spontaneous response, thereby improving workability and ensuring worker safety. Can be achieved.
