A visit history recording unit 23 for recording.
[0033]
The portable wireless device 2 is carried by a security guard or the like who rotates around the night and is carried on a waist belt or the like, and is configured to intermittently repeat automatic transmission without inputting operation.
[0034]
The lamppost 1 performs a basic operation of turning on and off the illuminating lamp based on a lighting command wireless signal from the portable wireless device 2.
[0035]
That is, when the wireless receiving unit 12 wirelessly receives a lighting command wireless signal that is an intermittent wireless alert signal for lighting the illumination lamp body unit 11, the light-on / off judging unit 14 sets the lighting command wireless in the wireless receiving unit 12. On condition that the signal has been wirelessly received, the lighting control unit 13 is instructed to control the lighting of the illuminating lamp body unit 11 for a predetermined time, while the wireless receiving unit 12 receives the lighting command wireless signal. If not, an instruction is given to the lighting control circuit 13 to turn off the illumination lamp body 11, and the lighting control circuit 13 turns on / off the illumination lamp body 11 based on these instructions. Control.
[0036]
The lamp post 1 performs the above-described basic operation of turning on and off the illumination lamp, and transmits the installation position data stored in the column position data storage unit 15 to the portable wireless device 2. Then, the portable wireless device 2 stores the received installation position data in the visit history recording unit 23.
[0037]
As described above, in the portable wireless device 2, the installation position data is sequentially stored each time the security officer visits the lamppost 1 and receives the installation position data signal. You can check the security route record.
[0038]
Next, the configuration of each part of the lamppost 1 and the portable wireless device 2 will be additionally described.
[0039]
The pole position data storage unit 15 of the lamppost 1 is configured by a control means such as a microcomputer and a memory, and is provided for storing the installation position data of the pole and performing read / write control thereof. Further, the wireless transmission unit 16 of the lamppost 1 is designed to use a frequency band that avoids the modulation frequency band used in the wireless reception unit 12, for example, and wirelessly transmits the installation position data to the vicinity of the lamppost 1. It is configured to make outgoing calls.

In particular, if the transmission specification to be changed is set to the transmission frequency band or the transmission power, re-communication can be easily performed.
[0046]
FIGS. 3 and 4 are diagrams for explaining an example of a method of setting the installation position data in the column position data storage unit 15 of the lamppost 1.
[0047]
The lamppost 1A shown in FIG. 3 further includes a GPS receiver. The GPS receiver 17 calculates position information based on a signal received from a GPS satellite (not shown), and outputs the calculated position information to the pole position data storage 15 as installation position data.
[0048]
If the GPS is used, the installation position data can be automatically acquired, and it is not necessary to store data before installing the lamppost, which is convenient when changing the installation position of the lamppost 1A.
[0049]
The communication device 3 of the management center is connected to the lamppost 1B in the second example of the system shown in FIG. This lamppost 1B further includes a power line carrier circuit 18 in addition to the configuration of the lamppost of the first example shown in FIG. 1, and has been transmitted as a power line carrier signal from the management center communication device 3 via the power line L. The position designation information is stored in the pole position data storage unit 15 as installation position data.
[0050]
The use of the power line L has the advantage of automatically acquiring the installation position data, as well as the advantage of being more reliable than wireless and requiring no other signal lines.
[0051]
In addition to the above-described method, there is a method in which the geographical construction position at the time of constructing the lamppost is stored and held in the pole position data storage unit 15 in advance.
[0052]
Next, a method of extracting the visit results from the visit history recording unit 23 of the portable wireless device will be described with reference to FIGS.
[0053]
The portable wireless device 2 </ b> A shown in FIG. 5 includes device connecting means including an external connector 25 and a communication conversion interface 24 for connecting to the externally connected device 4. The externally connected device 4 is a dedicated tool for reading the installation position data history from the visit history recording unit 23 (visit history database 23a), and is capable of reading a movement history, for example, by specifying a period or the like. In addition, from the viewpoint of privacy protection, inputting a password may be essential for reading data.
[0054]
The data read by the externally connected device 4 is loaded into the management center communication device 3 or the like, and is used for grasping the security route results and managing the attendance of security personnel.
[0055]
If the external connection device 4 is a device dedicated to the portable wireless device 2A, the risk of interception of information is extremely small as compared with data reading by communication, and the privacy of security guards is maintained.
[0056]
FIG. 6 is a diagram illustrating a method of loading installation position data (visit history information) in a system (third example) using a wireless communication network such as a public wireless network.
[0057]
The portable wireless device 2B used in this example includes portable communication means 26 having a portable communication function such as e-mail, reads out the installation position data recorded in the visit history database 23a, and The data is transmitted to the management center device 4 via the wireless relay station 5.
[0058]
Since a wide range of wireless communication networks are used, security route results and the like can be centrally managed by a single management center.
[0059]
FIG. 7 shows an example of a streetlight-pole-based security management system including a power line-compatible streetlight pole 1B adopted in the example of FIG. 4 and the portable wireless device 2 adopted in the example of FIG. FIG.
[0060]
In this example, the portable wireless device 2 reads out the installation position data stored in the visit history database 23a, wirelessly transmits the installed position data to the lamppost 1B, and loads the data into the management center communication device 3 via the power line L. That is, the visit history information is indirectly sent to the management center communication device 3 via the lamppost 1B and the power line.
[0061]
Here, the installation position data is read from the visit history database 23a and transmitted. However, when the lamppost 1B receives the lighting command wireless signal, the installation position data is transmitted not only to the portable wireless device 2 but also to the portable wireless device 2. , May also be transmitted to the management center communication device 3 at the same time. That is, the lighting command wireless signal in this case includes the meaning of the history transfer command.
[0062]
Since the visit history information is transmitted via the power line L, reliable information collection can be realized. Further, since the power line L is used, a wide range of information can be collected.
[0063]
Loading of the visit history information described with reference to FIGS. 6 and 7 to the management center communication device 3 may be performed each time a lamppost is visited (real-time loading), or may be collectively performed, for example, daily ( Batch loading).
[0064]
In addition, a portable wireless device 2B having a portable wireless function (see FIG. 6) is employed for the power line carrier method shown in FIG. 7, and as shown in FIG. The transmission may be performed alternately. At this time, the periods of the installation position data histories to be transmitted may be overlapped, and only the information in which the two information coincide during the same period may be valid. Of course, both types of transmission may be performed simultaneously.
[0065]
As a result, since data is transmitted by both the power line and the wireless method, more reliable security route record management can be realized.
[0066]
Loading of the visit history information described above to the management center communication device 3 may be performed based on a request signal from the management center communication device 3 as shown in FIG.
[0067]
In particular, in the case of batch loading, the load of both devices can be balanced by giving an instruction to perform loading based on the operation of the operator during a time period when the operation rate of the management center communication device 3 or the portable wireless device 2 is low.
[0068]
Next, features of the management center communication device 3 will be described.
[0069]
FIG. 10 is a diagram showing a display screen 3a of the management center communication device 3.
[0070]
The management center communication device 3 stores map data including the geographical arrangement of the lamppost 1 in advance, and displays the visit position on the map data screen A based on the visit history information sent from the portable wireless device 2. Is displayed.
[0071]
An individual identification ID is assigned to the portable wireless device 2, and when the identification ID is operated and designated by the management center communication device 3, the movement route and the current position of the portable wireless device 2 are displayed together with the map data.
[0072]
As a result, the operator of the management center can visually recognize which area on the map the security guard is / has guarded.
[0073]
In the case of real-time loading, the management center communication device 3 determines whether or not the portable wireless device 2 has moved a fixed distance within a fixed time based on the installation position data sent from the portable wireless device 2, When it is determined that such a movement has not been made, an automatic notification is made to an emergency management center such as the police.
[0074]
By the way, even if a guard is stuck by a thug while guarding and cannot move, he / she can immediately save the lives because he / she automatically notifies the police, judging that he / she is not moving as an abnormal situation.
[0075]
In addition, the automatic notification to the police may not be performed, and the automatic notification may be performed by an alarm sound or the like in the management center.
[0076]
【The invention's effect】
As can be understood from the above description, the lamppost-based security management system of the present invention transmits the geographical installation position data stored in the pole position data storage unit wirelessly for the lamppost, and the security guard for the portable wireless device. Since the installation position data is sequentially stored each time the installation position data signal of the lamppost visited is received, the security route movement history can be automatically saved, and the security route results can be confirmed later.
[0077]
According to the second aspect, the error detection of the installation position data signal is performed, and when the signal has an error, the re-communication is performed according to the different transmission specifications, so that the environmental noise in the wireless communication can be reliably avoided.
[0078]
According to the third aspect, since retransmission is performed by changing the transmission frequency or transmission power, retransmission can be easily performed.
[0079]
According to the fourth aspect, the geographical construction position at the time of the construction of the lamppost is stored and held in the pole position data storage unit in advance, so that there is no need to devise any means for acquiring the position data.
[0080]
According to the fifth aspect, since the GPS light receiving section is provided on the lamppost, the installation position data can be automatically acquired at any time, and there is no need to store the data before installing the lamppost.
[0081]
According to the sixth aspect, since the installation position data is acquired from the management center communication device by the power line carrier method, in addition to the merit that it can be automatically acquired, it is more reliable than wireless and does not require another signal line. There is also a merit of.
[0082]
According to the seventh aspect, since the installation position data (visit history information) is loaded using an externally connected device, there is less danger of the information being intercepted as compared with the data readout by communication, and the privacy protection of the security guard is protected. There is an effect on the surface.
[0083]
According to claim 8, since the visit history information is transmitted via the power line via the lamppost, reliable information collection can be realized. In addition, since power lines are used, a wide range of information can be collected.
[0084]
According to the ninth aspect, since a wireless communication network is used, the use of a network that can be used in a wide range makes it possible to centrally manage security route results and the like by a single management center. If both the power line carrier and the wireless system are alternately or redundantly implemented, more reliable security route management can be realized.
[0085]
According to the tenth aspect, since the portable wireless device returns the installation position data based on a request from the management center, especially when loading in batch, the loading is performed during a time period when the operation rate of the management center communication device or the portable wireless device is low. In this case, the load of the device can be balanced.
[0086]
According to the eleventh aspect, in the management center communication device, the visit position is displayed on the map data screen according to the transmitted installation position data of the lamppost for each portable wireless device. The operator can visually recognize where on the map the security guard is guarding.
[0087]
According to the twelfth aspect, in the management center communication device, since the stoppage of the guard is determined based on the installation position data transmitted from the portable wireless device, it is assumed that the guard is stuck by a thug and cannot move. However, since it is possible to automatically notify the police immediately, it is possible to quickly save lives.
