DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a tunnel, an underground power plant,
The present invention relates to an emergency communication system when an abnormality occurs in an underground space such as an underground mall.

[0002]

2. Description of the Related Art Conventionally, when constructing a site having a large underground space such as a long tunnel, an underground power plant, an underground shopping mall, etc., when an abnormal situation such as fire, flood, gas outbreak or the like occurs, broadcasting in the hall, lighting, etc. The operator was informed of the occurrence of an abnormal situation by flashing light. In addition, when an abnormal situation occurred when constructing a small underground space, the occurrence of the abnormal situation was notified by a verbal message from a staff member.

[0003]

However, in the method of reporting the occurrence of an abnormal situation by on-site broadcasting, noise from construction machines and the like becomes an obstacle, and it is difficult to communicate the occurrence of the abnormal situation to all workers. There is. In addition, in the method of notifying the occurrence of an abnormal situation by blinking a light or the like, it is possible to inform that the abnormal situation has occurred, but it is not possible to tell what kind of abnormal situation has occurred. For this reason,
In some cases, a telephone call for confirmation is made by a worker to a management office or the like, and confirmation telephone calls are concentrated at one time, resulting in a state where telephone communication is impossible. Further, when a power outage occurs, the communication method by blinking the lighting or the like cannot be used. In addition, the method of verbal messengers may delay communication,
It may not be possible to reliably contact all workers.

The present invention has been made in view of such a problem, and an object of the present invention is to provide an emergency system capable of promptly and reliably transmitting information on occurrence of an emergency and how to deal with it to all workers. To provide a communication system.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides a plurality of sensors provided at a work site, and a sensor for detecting an abnormality. An emergency communication system comprising: means for generating information for wireless transmission; and a pager receiver for receiving and displaying the emergency information.

[0006]

According to the present invention, when a plurality of sensors provided at a work site detect an abnormality, emergency information corresponding to the abnormality is transmitted by radio, and each worker can know the emergency information by a pager receiver. .

[0007]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a schematic cross-sectional view of a construction site in an underground space in which an emergency communication system according to one embodiment of the present invention is used, and FIG. 2 is a diagram illustrating a hardware configuration of the emergency communication system. In FIG. 1, 1 is an underground space under construction. This underground space is an underground space for a long tunnel, an underground power plant, an underground mall, and the like. Reference numeral 3 denotes an office provided on the ground. As shown in FIG. 2, a computer 17, a telephone 19, and a radio page central base station device 21 are installed in the office 3.

In FIG. 1, reference numeral 5 denotes a vertical shaft, and 7 denotes an inclined shaft.
Reference numerals 9a, 9b to 9m denote sensors installed at various places in the field. The sensors 9a, 9b to 9m detect the occurrence of fire, gas, water, and the like, and send an abnormality detection signal to the computer 17.

In FIG. 2, when the computer 17 receives the abnormality detection signal sent from each of the sensors 9a to 9m,
The situation is determined according to each abnormal situation, an optimal evacuation measure is selected, and emergency information including an evacuation route and the like is sent to the radio paging central base station device 21. The radio paging central base station device 21 transmits emergency information sent from the computer 17 via antennas 11a to 11t on radio waves in the VHF band. 11a
Numerals 11t denote small whip-type antennas, which are installed in places with good propagation efficiency at various places in the field and wirelessly transmit emergency information sent from the radio base station 21.

Reference numerals 13a and 13b to 13n denote workers,
Each worker has a pager receiver 15a, 15b to 15n having a small display.

FIG. 3 is a perspective view of the pager receiver 15. The pager receiver 15 has a display 23, receives emergency information sent from the computer 17 via the antennas 11a to 11t, and
3 is displayed. The pager receivers 15a to 15n are attached to the helmets or the safety belts of the workers 13a to 13n. When receiving emergency information, the pager receivers 15a to 15n sound (buzzer sound) and vibrate. Display emergency information. Although the pager receiver 15 shown in FIG. 3 is a card type, the shape of the pager receiver may be other shapes such as a pencil type.

Next, a method of communicating emergency information according to the present embodiment will be described with reference to the flowchart of FIG. When an abnormality occurs at the site (Step 401), an abnormality detection signal is sent from the sensor 9 that has detected the abnormality to the computer 17 (Step 402). The computer 17 determines the situation based on the transmitted abnormality detection signal and generates emergency information (step 403). For example, an optimal evacuation measure is selected according to each case such as fire, flood, gas generation, etc., an evacuation route and the like are determined, and this is used as emergency information.

Next, emergency information is sent from the computer 17 to the central station 21 (step 40).
4). The emergency information is wirelessly transmitted to the pager receiver 15 via the antenna 11c (step 405), and the pager receiver 15 that has received the emergency information sounds and vibrates and displays the emergency information on the display 23 (step 406). ). Thereby, the pager receiver 1
The worker 13 holding 5 can know the occurrence of the emergency and the details of the emergency, and evacuate according to the evacuation route displayed on the display 23.

As described above, according to the present embodiment, the occurrence of an emergency, the details of the emergency, the evacuation route, and the like can be quickly and reliably transmitted to all the workers.

In this embodiment, the construction site in the underground space has been described as an example, but the present invention can be used also on the ground site.

The emergency contact system can be used for other than emergency contact. For example, a contact can be made in normal times using the dual call mode of the pager receiver 15. In addition, the arrival of radio waves can be confirmed by sending a time signal or the like at regular times such as rest periods (for example, 10:00, 12:00, 13:00, 15:00,...).
In the above-described embodiment, an example in which the pager receiver 15 is simultaneously paged has been described. However, the pager receiver 15 can be individually called. Call only those who need to attend this meeting, for example to hold a process meeting. Furthermore, if this individual call function is used,
It can be used to find a worker when a disaster occurs and the worker becomes unconscious and cannot evacuate. That is, if only this worker is called individually,
Since the pager receiver 15 makes a sound or the like, an operator can be easily found by relying on this sound.

[0017]

As described above, according to the present invention, the occurrence of an emergency can be promptly and reliably transmitted to all workers.
