However, the prior art disclosed in Patent Document 1 has a problem that a wasteful operation is frequently performed due to mischief because an emergency warning is unconditionally performed when an emergency call switch is pressed. To prevent this, only requests from mobile terminals with registered identification codes are handled, but the server must be called from the mobile terminal and there is a risk that it will not be in time for an emergency. .
Moreover, since an emergency warning device used only for emergency warning is attached to the security light pole, the cost performance of the facility is not necessarily good.

In view of such a problem, the present invention normally installs a reader / writer and an emergency button in a push button box that is always installed at an intersection, so that it is normally used for signal operation and possesses an IC card in an emergency. Only when a person presses the emergency button, the emergency operation is notified to the external device, the malfunction due to mischief is reduced, the accuracy of urgency is increased, and the cost performance of the equipment can be improved. The purpose is to provide.

When the ID is read and it is confirmed that the emergency button is pressed, the ID and the fact that an emergency has occurred are transmitted to the external device. To.
The signal operation device according to the present invention includes a reader or a reader / writer that reads information on a non-contact IC card possessed by a registered person (basically, a visually handicapped person or an elderly person who is called a traffic weak person, or a person registered in advance). And an emergency button that is effective only when the non-contact IC card is brought close to the reader or reader / writer, and a control circuit that transmits the information to an external device in an emergency, together with a request button.

According to a second aspect of the present invention, the control circuit further includes notification means for notifying that the emergency has occurred, and after transmitting the ID and the fact that the emergency has occurred to the external device, When the information indicating that the ID matches the registered ID is received, the notification unit is driven.
In addition, the signal operating device of the present invention further includes notifying means such as an alarm lamp and an alarm sound for informing the surroundings that an emergency has occurred and intimidating an unauthorized person. This notification means is effective only after confirming that the external device is an alarm based on the registered ID.
According to a third aspect of the present invention, when the ID or weak bit recorded in the non-contact information recording medium is read by the reader or reader / writer, the control circuit sets the blue lighting time of the pedestrian signal lamp to a predetermined time. It is characterized by extending.
People who use non-contact information recording media are basically vulnerable people. Therefore, when the traffic weak person approaches the non-contact information recording medium in the vicinity of the reader or the reader / writer, it is determined that the person crosses the pedestrian crossing and the time of the green light is extended.

According to a fourth aspect of the present invention, when the non-contact information recording medium does not communicate with the reader or the reader / writer even when the emergency button is pressed, the control circuit determines that the operation is invalid and invalidates the operation. It is characterized by that.
The emergency button may be pushed by mischief. If an emergency is transmitted only by this operation, unnecessary emergency situations may occur frequently. Moreover, it becomes impossible to specify the unauthorized person. Therefore, in the present invention, when only the emergency button is pressed, it is determined as an unauthorized operation.
According to a fifth aspect of the present invention, when the ID recorded on the non-contact information recording medium is read by the reader or reader / writer on the crossing start side, the control circuit sets a blue lighting time of the pedestrian signal lamp to a predetermined value. If the non-contact information recording medium in which the ID is recorded before the blue lighting time expires communicates with the reader or reader / writer on the crossing end side, the extension of the blue lighting time is terminated at that time. Features.
According to the present invention, when the ID recorded on the non-contact information recording medium is read by the reader or reader / writer on the crossing start side, the green light time is automatically extended. However, if the crossing person using the non-contact information recording medium finishes before the blue lighting time expires, it is not necessary to extend the subsequent green light.

When the signal controller 45 receives the signal, it requests a green signal (S2). Next, it is checked whether the IC card 200 and the reader / writer 100 have started communication (S3). When communication is started (YES route in S3), it is checked whether the emergency button 32 has been pressed. (S4) If the emergency button 32 is not pressed (NO route in S4), the process proceeds to step S5 to determine whether “weak bit” is recorded on the IC card 200 (S5), and “weak bit”. If ON is ON, the control circuit 37 transmits a green signal extension to the signal controller 45 (S6), and when the signal controller 45 receives the signal, it requests a green signal (S7). On the other hand, if the “weak bit” is OFF in step S5, the control circuit 37 requests the signal controller 45 for a blue signal (S8).

When the emergency button 32 is pressed in step S4 (YES route in S4), emergency information is transmitted to the system of the police station 38 through the cable 39 together with the ID recorded in the IC card 200 (S9). ). Since the ID registered beforehand is memorize | stored in the server in a police station, it is searched whether received ID is registered (S10). As a result, if registered (YES route in S10), the control circuit 37 is informed via the cable 39. When the control circuit 37 receives the signal, the control circuit 37 determines that the emergency is based on the registered ID, rotates the rotating lamp 36 (S11), and the police officer is dispatched to notify the pre-registered neighbors. (S12). If the ID is not registered in step S10 (NO route in S10), the process ends as it is.
On the other hand, if communication with the IC card 200 is not made in step S3 (NO route in S3) and the emergency button 32 is pressed (YES route in S13), the operation is invalidated because it is determined to be mischief (S14).

  FIG. 7 is a flowchart for explaining the operation of the signal operating device according to the second embodiment of the present invention. This will be described with reference to FIG. When the person holding this IC card brings the IC card 200 close to the reader or reader / writer 100, communication is started (S21). The control circuit 37 sends a signal extension signal to the signal controller 45, and proceeds to step S23. When the signal controller 45 receives the signal, it extends the time of the green signal (S23). When the ON time is reached (YES route in S24), the green light is turned on (S25). Then, before the time of the green light expires (NO route in S26), it is checked whether the reader or reader / writer 100 on the crossing end side communicates with the IC card with the same ID (S29), and the reader or When the reader / writer 100 communicates with an IC card having the same ID (YES route in S29), the extension time of the green light is terminated at that time (S30), and the process returns to step S26. When the time of the green light ends in step S26 (YES route in S26), the green light blinks and then turns off (S27). Thereby, useless extension time can be cut and traffic can be smoothed.

As described above, according to the present invention, the signal operating device 300 includes a reader or reader / writer 100 that reads information on the IC card 200 possessed by a registered person, and the IC card 200 is brought close to the reader or reader / writer 100. Since the emergency button 32 that is effective only at the time and the control circuit 37 that transmits the information to the police station 38 in the event of an emergency are provided together with the request button 34, not only a signal operation but also malfunction due to mischief of the emergency button 32 is provided. This reduces the urgency accuracy and improves the cost performance of the equipment.
In addition, the control circuit 37 further includes a rotating lamp 36 for notifying that an emergency has occurred. After the fact that the emergency has occurred and the ID are transmitted to the police station 38, the ID is registered from the police station 38. When the ID is received, the rotating lamp 36 is driven, so that an unnecessary emergency operation for an unregistered ID can be prevented in advance.
