If the unique identification signal UIDS has not been received, the RFID identification number reading process of S100 is repeated without extracting the identification number IDn (not shown).

  If the unique identification signal UIDS has been received, the identification number IDn is extracted (S110), and then the detected identification is sent to the monitoring device computer 43 via the network device 49 and the communication cable 51. The ID ID + detector number is transmitted to the location management computer that transmits the number IDn and the detector number SSm unique to the read / write device 41 to the monitoring device computer 43 (S120), and the RFID identification number is read. Return to the process (S100).

  By repeating the processes of S100 to S120, each time the wireless IC tag 35 approaches the reading / writing device 41, the identification number IDn of the approaching wireless IC tag 35 is read, and the identification number IDn is set. The information of the identification number IDn of the wireless IC tag 35 is transmitted to the monitoring device computer 43 together with the information of the detector number SSm of the read / write device 41 that has been read.

  As a result, the wireless IC tag 35 from which the identification number IDn has been detected is built in the helmet 33 and worn by the worker 25 as shown in FIG. A rule that only the worker 25 wears or a configuration in which the worker 25 wearing the helmet 33 is recorded or registered in the monitoring device computer 43, so that the worker 25 who passes near the reading / writing device 41. Is specified by the monitoring device computer 43.

FIG. 9 is a flowchart of a location area management processing routine that is repeatedly executed by the monitoring device computer 43.
In this process, first, by the process of S120 in FIG. 8, the ID number + detector number that inputs the identification number IDn and the detector number SSm transmitted from the reading / writing device 41 is received (S200). ), The ID number for extracting the identification number IDn of the wireless IC tag 35 and the detector number SSm of the reading / writing device 41 from the received identification number IDn, the detector number SSm, and the detector number are extracted. (S210). When the identification number IDn and the detector number SSm are extracted, the ID number for determining whether the identification number IDn is already stored in the detection ID number column 85 of the detector database 77 shown in FIG. The search process is performed (S220). On the other hand, if the identification number IDn and the detector number SSm are not extracted, the process returns to S200 as it is (not shown).

  When the identification number IDn has not already been stored in the detection ID number column 85 of the detector database 77, that is, for example, as shown in FIG. When it is stored in the detector database 77 for the first time, for example, when it passes near the reading / writing device 41 installed at the entrance 23 which is the entrance of the sensor (S220), the corresponding detection in the detector database is performed next. A process of storing the identification number IDn (ID number) in the machine number column 83 is executed (S240), and the head area management process is temporarily terminated.

  That is, the identification number IDn of the read wireless IC tag 35 is written in the detection ID number column 85 corresponding to the detector number column 83 of the detector number SSm of the read / write device 41 that has been read. For example, when the reading / writing device 41 with the detector number SS1 reads the wireless IC tag 35 with the identification number ID1, as shown in FIG. 5, the detection ID number field 85 corresponds to the detector number SS1. The identification number ID1 is written. Thereby, the information of the wireless IC tag 35 and the reading / writing device 41 that has detected the wireless IC tag 35 is recorded in the detector database 77 shown in FIG.

  If it is determined that the identification number IDn has already been stored in the detection ID number field 85 in the determination of whether the ID number exists in S230, the management area determination update process shown in FIG. (S250), a process of updating the identification number IDn (ID number) in the corresponding detector number column 83 of the detector database 77 is executed (S260).

  That is, when the wireless IC tag 35 is already in the mine 3 and is moving, as shown in FIG. 2, first, the user gets on the elevator device 17 and then gets on the trolley train 27, and reads / reads one after another. It passes near the writing device 41, and information including the identification number IDn and the detector number SSm is transmitted one after another by the ID number detection notification process of FIG.

In order to reflect the state in the detector database 77, the process of S260 is performed.
For example, this time, when the signal of the identification number ID1 is transmitted from the reading / writing device 41 of the detector number SS2, if the identification number ID1 is already stored in the detection ID number column 85, the detector number The update process of deleting the identification number ID1 of SS1 and writing it in the detection ID number column 85 of the detector number SS2 is executed. By doing so, the wireless IC tag 35 moving in the mine 3, that is, the current position of the worker 25 is managed by the detector database 77 so as to be grasped. By variously processing the information in the detector database 77, the personnel management computer 75 refers to the salary supply or refers to the purpose of rescue in the event of an accident.

Next, the management area determination update process of FIG. 10 will be described.
In this process, first, an old and new detector number + ID number input for reading the identification number IDn, the detector number SSm, the updated identification number IDn, and the detector number SSm before being updated in S260 of FIG. Processing is executed (S300). For example, ID1 and SS1 are read as identification number IDn and detector number SSm before update, and ID1 and SS2 are read as identification number IDn and detector number SSm after update. This is because the wireless IC tag 35 with the identification number ID1 is the same as the reading / writing device 41 with the detector number SS1, for example, the reading / writing device 41 (SS1) near the mouth 23 shown in FIG. This is an example in the case of passing near the reading / writing device 41 of the detector number SS2 installed at the entrance of the left side hole 11 at the branch point 31 of the 9th basement floor 107.

  After executing the new and old detector number + ID number input process in S300, the old and new detector numbers and ID numbers are extracted, for example, the old SS1, ID1, new SS2, and ID1 are extracted (S310). ) Based on the new and old detector numbers SS1 and SS2, the management area code determination process between the two detector numbers for determining the area where the wireless IC tag 35 having the identification number ID1 is present is performed (S320).

  For example, in the management area code determination process between both detector numbers, as shown in FIGS. 2 and 6, the vertical hole 9 and the horizontal hole 11 are separated from the reading / writing device 41 by the management area codes E1, A1, and A2. As shown in FIG. 2, the area between the detector number SS1 and the detector number SS2 is determined as the management area code E1, and the detector number SS2 and the adjacent detector number SS3 are determined. The management area code A2 is determined between the reading / writing device 41 and the reading / writing device 41. If the old and new identification numbers are updated from SS1 to SS2 when determined in this way, it is estimated that the wireless IC tag 35 has moved from the management area code E1 to the management area code A1. Accordingly, in the process of S320, it is determined that the new management area code has moved from E1 to A1.

  Next, based on the old and new management area codes determined in S320, the identification number IDn (ID number) stored in the current ID number column 95 of the corresponding old and new management area code column 93 of the management area database 79 of FIG. Is updated (S330), and the management area determination update process is temporarily terminated. For example, if the old and new management area codes are updated from E1, ID1 to A1, ID1, the identification number ID1 stored in the column 109 which is the current ID number column 95 of the management area code E1 is deleted and managed. The update process written in the column 111 of the current ID number column 95 of the area code A1 is performed.

  The management area database 79 shown in FIG. 6 is updated by the management area determination update process shown in FIG. 10 and the management area code where the worker 25 wearing the wireless IC tag 35 is present can be immediately grasped. For example, it is possible to grasp the current position of the worker 25 by displaying the image of the contents of the management area database 79 in FIG.

  Next, the management process for each ID number in FIG. 11 will be described. This process is a process for constructing the ID number database 81 shown in FIG. This ID number database 81 records the reference information of the labor management of the worker 25, here, the place where the worker 25 is engaged in excavation work and the time, so that the worker 25 is appropriately engaged in the work. Create materials to determine whether or not to calculate salary.

  In this management process for each ID number, the management area code and the ID number IDn are read and read from the management area database 79 shown in FIG. 6 (S400), and then, for each ID number IDn, for example, ID1 is first , E1, and then ID2 extract the management area code in the management area code column 103 having the ID number (identification number IDn) corresponding to the ID number column 101 extracted, as in E1. In addition to writing, the ID number database 81 is updated to delete the same management area code that has already been written (S410), and the update time when this update is performed, that is, the management area code (113 shown in FIG. 7). And the time when the management area code was written (115 in the figure) and the time when the management area code was deleted (117 in the figure) When the time after the process of writing in the column 105 (S420), temporarily ends the ID number for each management process. The stop area code and the management area code written in the time column 105, the time when the management area code was written, and the deleted time are, for example, conditions such as when the time from writing to deletion is 1 hour or more. It may be added. By adding such a condition, a record that has just passed through the management area does not remain in the stop area code and time column 105. Further, the current time may be stored in the portion of the deleted time (shown 117 in the figure) until it is deleted (shown in 119).

  The ID number database 81 shown in FIG. 7 constructed by the ID number management process of FIG. 11 described above creates information on the destination and work position of the worker 25, and the attendance of the worker 25 is determined by the personnel management computer 75. It becomes possible to refer to it by the processing by. Also, the stop position and time are referred to when an accident occurs.

FIG. 12 is a flowchart of the accident report processing routine.
This accident report process is repeatedly executed by the accident detection apparatus 121 shown in FIG.

  Although the detailed illustration of the structure of the accident detection device 121 is omitted, a storage box attached to the wall surface 39 of the side hole 11 and a conventional explosion-proof fire detection sensor attached to the storage box, for example, A differential fire detection sensor, a constant temperature fire detection sensor, a smoke detection sensor, etc., and a gas detection sensor, for example, a sensor that detects flammable gases such as harmful carbon dioxide, carbon monoxide, methane gas, and coal gas, An atmospheric pressure sensor that detects a sudden rise in atmospheric pressure, a management microcontroller, and a network device are provided. In addition, the storage box is connected to the tunnel connection pipe 55, and the network device is connected to the monitoring device computer 43 via the communication cable 51. This accident detection device 121 is installed as much as necessary to detect and notify an accident, and the greater the number of attachments, the earlier the detection of an accident, the discovery in a narrow area, and the countermeasure.

The management microcontroller executes the accident report process shown in FIG.
First, the fire detection sensor performs a process of inputting a signal (reporting) that detects a fire (S500), and then determines whether the fire detection sensor has reported (S510), and the fire detection sensor reports. Then, the sensor unit number + fire occurrence is sent to the location management computer that transmits the unique identification number Ji (i is a unique numerical value) of the accident detection device 121 and the fire alarm signal to the monitoring device computer 43. An information signal transmission process is performed (S520). The unique identification number Ji of the accident detection device 121 is, for example, as shown in FIG. 2, the one installed in the management area code A2 is the identification number J1, and the one installed in the management area code AA1 is the identification The one installed in the number J2 and the management area code AB1 is set as the identification number J3.

  In addition, after the process of S520 or when it is determined that the fire detection sensor has not issued (S510), a signal indicating that the gas detection sensor has detected harmful gas, explosive or flammable gas is input. Processing is performed (S530), and it is determined whether or not the gas detection sensor has detected (reported) gas (S540). If the gas detection sensor detects gas, then the monitoring computer 43 detects an accident. A sensor unit number + gas detection signal transmission process is performed on the location management computer that transmits the unique identification number Ji (i is a unique numerical value) of the apparatus 121 and the gas detection signal (S550).

  Next, after the processing of S550 or when it is determined that the gas detection sensor is not reporting (S540), a signal that the atmospheric pressure detection sensor detects a sudden rise in atmospheric pressure, that is, an explosion shock wave, is then sent. An input process is performed (S560), and it is determined whether the atmospheric pressure sensor detects a shock wave due to an explosion or the like (S570). If the atmospheric pressure sensor detects a sudden rise in atmospheric pressure, Then, the sensor unit number + atmospheric pressure sudden rise signal transmission processing is performed to the location management computer that transmits the unique identification number Ji (i is a unique numerical value) of the accident detection device 121 and the atmospheric pressure sudden rise signal to the monitoring device computer 43. (S580).

  By repeating this accident notification process, there is a temperature rise or combustion gas generation due to the occurrence of a fire at the location of the accident detection device 121, the presence of harmful gas, explosive or flammable gas, explosion A signal indicating that there is a sudden increase in the atmospheric pressure due to the above or the like is transmitted to the monitoring device computer 43 together with the unique identification number Ji of the accident detection device 121.

The monitoring apparatus computer 43 that inputs a signal that conveys a state associated with the occurrence of such an accident repeatedly executes an accident response process as shown in FIGS.
In this accident response process, first, a process of receiving the sensor unit number + fire alarm signal output by the process of S520 in FIG. 12 is performed (S600), and it is determined whether the fire alarm signal is received (S610). When the fire alarm signal is received, the sensor unit number extraction process for detecting the unique identification number Ji of the accident detection device 121 is first performed (S620), and then the unique identification number Ji of the accident detection device 121 is detected. And the occurrence of a fire accident that notifies the occurrence of a fire by sound or light emission is performed (S630). The display of the unique identification number Ji of the accident detection device 121 is performed on a display (not shown) of the monitoring device computer 43, and notification of the occurrence of a fire by sound or light emission is not shown on the display (not shown) of the monitoring device computer 43. This is realized by ringing a fire alarm facility, for example, a bell of a fire alarm facility.

  Next, after notification of the occurrence of a fire accident (S630) or when it is determined in S610 that a fire alarm signal has not been received, the sensor unit number + gas output by the processing of S550 in FIG. Processing for receiving the detection signal is performed (S640), it is determined whether the gas detection signal is received (S650), and when the gas detection signal is received, first, the unique identification number Ji of the accident detection device 121 is detected. Sensor unit number extraction processing is performed (S660), and then the unique identification number Ji of the accident detection device 121 is displayed, and the occurrence of a gas ejection accident that informs the occurrence of a gas ejection accident by sound or light emission is performed (S670). ). The display of the unique identification number Ji of the accident detection device 121 is performed on a display (not shown) of the monitoring device computer 43, and notification of the occurrence of a gas ejection accident by sound or light emission is performed on the display (not shown) of the monitoring device computer 43. This is realized by ringing of a gas ejection accident notification bell and buzzer (not shown) or message broadcasting by an artificial announcement unit.

  Next, after the notification of the occurrence of a gas ejection accident (S670) or when it is determined in S650 that the gas detection signal has not been received, the sensor unit number output by the processing of S580 in FIG. A process of receiving a pressure sudden rise signal is performed (S680), it is determined whether an atmospheric pressure sudden rise signal has been received (S690), and when an atmospheric pressure sudden rise signal is received, first, a unique identification number of the accident detection device 121 is obtained. The sensor unit number for detecting Ji is extracted (S700), and then the unique identification number Ji of the accident detection device 121 is displayed, and the occurrence of the explosion accident is reported to notify the occurrence of the explosion accident by sound or light emission ( S710). The unique identification number Ji of the accident detection device 121 is displayed on a display (not shown) of the monitoring device computer 43, and the occurrence of an explosion accident is notified by sound or light emission. This can be realized by sounding a siren for notifying an explosion accident or message broadcasting by an artificial announcement unit.

The notification of the occurrence of an accident is performed by the processing of S600 to S710.
When an accident occurs in this way, it is next determined whether or not the worker 25 is damaged at the location of the accident in the mine 3, and if it is damaged, the accident is collected and the victim is rescued. Need to do. In order to rescue such a victim, it is necessary to clarify whether or not the worker 25 in the accident occurrence area exists. In addition, it is necessary to accurately know the position of the worker 25 who has been damaged at the rescue site.

Such a process useful for rescue is executed in the processes of S720 to S820 of FIG. 14 performed following the accident response process of FIG.
First, based on the unique identification number Ji of the accident detection apparatus 121 extracted by the process of S620, determination of the fire accident occurrence spreading area where the occurrence of a direct fire is detected, for example, the identification number J1 shown in FIG. When the accident detection apparatus 121 with the number J2 notifies the occurrence of a fire accident, the management area codes A2, AA, AA1 are determined as the fire accident occurrence area. Further, based on the fire accident occurrence area, a process is performed in which management area codes AA2, AA3 (not shown) on the deeper side of the lateral hole 11 than the management area code AA1 are determined as far areas (S720). ). This far area does not directly cause a fire accident, but in order to escape from the management area to the ground part 13, it is inevitable that passage through the fire occurrence area is unavoidable. Therefore, it is necessary to rescue the worker 25 in the fire spreading area and rescue the worker 25 in the far area.

  Next, based on the unique identification number Ji of the accident detection device 121 extracted by the processing of S660, determination of the gas ejection accident occurrence spreading area where the occurrence of gas ejection is detected, and further based on the gas ejection accident occurrence spreading area. The far area is determined (S730).

  Furthermore, based on the unique identification number Ji of the accident detection device 121 extracted by the process of S700, the determination of the explosion accident spreading area where the occurrence of the sudden increase in atmospheric pressure is detected, and further based on the explosion accident spreading area. The far area is determined (S740).

The processes of S720 to S740 described above are processes for determining the occurrence of a single accident and the far area.
Hereinafter, in the process of S750, the results of the processes of S720 to S740 are combined to determine the three types of combined accidents, fire accidents, gas ejection, explosion occurrence areas, and far areas, and in the process of S760. In combination with the results of the processes of S720 to S740, fire accidents that are two types of combined accidents, the determination of the explosion spreading area, and the area of the farther are determined, and the process of S720 to S740 is performed in the process of S770 In addition, two types of combined accidents are carried out by determining the two types of combined accidents, fire accidents, determining the gas spillover area, and determining the far area, and combining the results of S720 through S740 in the process of S780. The determination of the area where the gas is blown out, the explosion spreading area, and the area beyond is determined, and based on the processes of S720 to S780, Carry out the creation of a situation integration map (S790). The accident occurrence situation integrated map created here is, for example, a diagram in which an accident situation is identified for each management area code as shown in FIG. For example, there is a map that indicates that “the management area code C4 is a fire accident, the management area code C5 is an explosion accident and a fire accident are both detected, and the management area code C7 is a far area”. Made.

  Next, a process of reading the ID number in the corresponding area on the accident occurrence integrated map from the management area database 79 is performed (S800), and an accident situation diagram is created by adding the ID number to the accident occurrence situation integrated map ( S810) A process for notifying the created accident situation diagram is performed (S820), and the accident handling process is temporarily terminated. The accident situation diagram created here is displayed, for example, as an image 131 as shown in FIG. 15. For example, “Management area code C4 indicates that a fire accident has occurred but an identification number (ID No.), management area code C5 detects both explosion and fire accidents, and the ID number currently in existence is ID △△, ..., management area code C7 is a far area, The ID number is ID OO... Accordingly, by displaying the image 131 of the accident situation diagram on the display 61 of the monitoring panel 65 shown in FIGS. 4 and 16 when the accident occurs, the rescue worker 25 who has seen the display 61 can understand the contents and scale of the accident. Therefore, it is possible to understand the position and the number of the workers 25 who are affected by the disaster, and it is possible to perform a prompt and appropriate rescue operation. Further, at the time of the rescue operation, the rescue operation can be performed more appropriately by using the interphone 67 of the monitoring panel 65 to notify the rescue related instructions.

  Also, the image 131 of the accident situation diagram is transmitted to the wireless information terminal device 69 for premises as shown in FIG. 17 using the wireless device 71 shown in FIG. The rescue worker 25 possessing the information terminal device 69 or the disaster victim worker 25 may correctly understand the situation of the accident and perform a prompt and appropriate rescue operation or move to a retreat zone (not shown). It becomes possible.
