Based on this, the conductor can urgently notify the next stop station using the existing notification system and respond.

[0010]

Next, a first embodiment of the present invention will be described with reference to the drawings.

Referring to FIG. 1, the in-vehicle notification system includes:
A mobile phone 1 for outputting a predetermined special code including a special number and additional information for in-vehicle notification based on an operation input, an antenna 10 provided in each vehicle for receiving the special code, and an antenna provided in a specific vehicle for each antenna. Radio units A21 to D2 for demodulating or modulating the output signal
4 and a reporting device 30 provided in the conductor's compartment to receive a report of an in-vehicle incident.

The notification device 30 controls the call connection with the mobile phone 1 via the base station 20 and receives and identifies the notification information from the base station 20, and displays the information identified by the processing unit 31. It has a display unit 32 and a handset 33 for making a call with the mobile phone 1. In FIG.
The case where four wireless units are provided, that is, a case where there are four vehicles is illustrated, and the number of wireless units is determined according to the number of vehicles.

Further, the processing unit 30 retrieves a conversion table (not shown) in which the received special code is registered in advance and converts the special code into a corresponding display content. In this configuration, it is assumed that the downlink transmission power is adjusted for each sector divided for each antenna so that the mobile telephone in the vehicle is synchronized only with the downlink signal from the antenna installed in the vehicle. That is, the transmission power from the base station 20 is adjusted so as to synchronize only with the downlink signal from the antenna of the own vehicle and not with the downlink signal from the antenna in the other vehicle. According to the present invention, by transmitting a radio wave of an appropriate power value obtained by logical calculation and measurement from an antenna installed in the vehicle, the mobile phone in the vehicle is not a radio wave from a general base station,
It can be synchronized with the radio wave from the base station in the car.

FIG. 2 is a flowchart showing the flow of a processing procedure according to the first embodiment of the present invention. The operation will be described below with reference to FIGS. For example, when a sudden sick person is found in a car, the passenger uses his / her own mobile phone 1 and presses a predetermined in-vehicle emergency special number different from a normal mobile communication network numbering system, for example, number 119 without dialing 0. Furthermore, if a call is made by pressing another digit, for example, * if a call is possible, the special code and the in-vehicle special number and the press information as special codes are output from the mobile phone 1 (step 1: abbreviated as S1).

In this case, the passenger's mobile phone 1 is connected to the base station 2.
By performing the synchronization processing with 0, the communication state is closed in the vehicle. The signal transmitted from the mobile phone 1 in the vehicle is received by the base station 20 via the antenna 10 (S2).
The signal output from the mobile phone 1 is demodulated by one of the corresponding radio units A21 to D24 of the base station 20 (S3) and sent to the processing unit 31.

The processing section 31 connects the call with the mobile phone 1 that has transmitted the information, and receives a signal. Thereafter, the vehicle number is specified from the wireless unit that has received the signal (S4), and the case is identified by the in-vehicle emergency number dialed from the mobile phone 1.
The report category of the content of the accident is searched and identified (S5), and whether or not a call is allowed is identified (S6). Next, these results are output to the display unit 32 and displayed, for example, as shown in FIG.
7). If it is determined in S6 that the call is possible, the display unit 32
Hold the call even after the information is output to the
8). On the other hand, if it is determined in S6 that the call is not possible, the information is output to the display unit 32 and then the call is disconnected (S9).
In addition, it is also possible to output the display content by voice by using a voice memory (not shown) or the like.

Accordingly, after recognizing the emergency report category displayed on the display section 32, the category of possible / unavailable communication, and the vehicle number in which the incident or accident has occurred, the conductor can make a call if possible. After that, the existing notification system can inform the staff of the next stop station of the condition of the sick, and arrange for emergency personnel and other preparations.

Next, a second embodiment of the present invention will be described. FIG. 3 shows a configuration in a case where an in-vehicle notification system is realized using a PHS instead of a mobile phone.

The in-vehicle notification system is a base station that performs a radio communication between the PHS 2 that outputs a predetermined special code based on an operation input and the PHS 2 via an antenna 11 and performs modulation / demodulation processing, synchronization processing, and transmission / reception processing. And a notification device 40 provided in the conductor's compartment to receive a notification of an in-vehicle incident.

The notification device 40 transmits the PHS via the base station 12
, A display unit 42 for displaying information identified by the processing unit 41, and a handset for communicating with the PHS2. 43.

As in the first embodiment, the processing unit 40 searches the conversion table (not shown) for the received special code and converts it into the corresponding display content. In this configuration, it is assumed that the downlink transmission power is adjusted for each sector divided for each antenna so that the PHS in the vehicle is synchronized only with the downlink signal from the antenna installed in the vehicle. That is, the transmission power from the base station 12 is adjusted so as to synchronize only with the downlink signal from the antenna of the own vehicle and not with the downlink signal from the antenna in the other vehicle.

FIG. 3 is a flowchart showing the flow of a processing procedure according to the second embodiment of the present invention. The operation will be described below with reference to FIGS. For example, pickpocket in the car,
When a criminal case such as assault is found, the passenger presses a special number in the vehicle security, for example, dial 110 without dialing, and if a call is possible, press another digit, for example, * to make a call. On the other hand, when it is close to the crime scene and there is a possibility that a criminal may be found, if another digit, such as #, indicating that communication is impossible is pressed and called, these in-car special numbers and pressed information are output from the PHS (S11). In this case, the PHS2 of the passenger is in a closed communication state in the vehicle by performing a synchronization process with the base station 12. The signal transmitted from the PHS2 in the vehicle is received by the base station 12 via the antenna 11 (S1).
2). The signal output from the PHS 2 is demodulated and synchronized by the base station 12 (S 13), and sent to the processing unit 41.

The processing section 41 connects the call with the PHS 2 that has transmitted the information, and receives a signal. After that, the vehicle number is specified from the base station that received the signal (S14), the incident / accident report type is searched and identified by the in-vehicle security special number dialed from the PHS2 (S15), and further, whether or not a call is possible is identified. (S16). Next, these results are output to the display unit 42 and displayed, for example, as shown in FIG. 3 (S1).
7). If it is determined in S16 that the call is possible, the display unit 4
2 after the information is output, the call is held and the call is made (S1).
8). On the other hand, if it is determined that the call cannot be made in S16,
After outputting the information to the display unit 42, the call is disconnected (S1).
9). In addition, it is also possible to output the display content by voice by using a voice memory (not shown) or the like.

Therefore, after recognizing the security report category displayed on the display unit 42, the category of possible / unavailable communication, and the vehicle number in which the incident or accident has occurred, the conductor can make a call if possible. After that, the existing reporting system can inform the staff at the next stop of the crime case and arrange for the preparation of police officials.

[0025]

As described above, according to the present invention, in case of an accident or accident occurring in the vehicle, the emergency code can be set by pressing a special code consisting of a predetermined in-vehicle special number and additional information without dialing 0. Using a mobile phone terminal, a security report category, a call enable / disable category, and a vehicle number in which an incident or accident has occurred can be secretly and promptly reported to a conductor's cabin. In addition, by installing an antenna in each vehicle and synchronizing the passenger's mobile phone terminal with the base station provided in the vehicle, the vehicle is in a closed communication state in the vehicle and can reliably report even in a place where the radio wave environment is poor such as in a tunnel.
