[Detailed description of the device]

[0001]

[Industrial applications]

 The idea is to search for an emergency scene such as a rescue operation for an accident vehicle, a damaged vehicle, or various victims, and emergency medical activities, wandering of the elderly, kidnapping cases, and theft cases during cash transportation. Responding to wide area rescue equipment to deal with, especially in areas where there are many reflections of radio waves, such as in urban areas where tall buildings are forested, by using the communication satellite and GPS mutually, it is possible to provide highly accurate rescue in a short time. Wide area rescue device that can be active.

[0002]

[Prior art]

 The applicant has previously applied for a wide area rescue system using a directional antenna group and an omnidirectional antenna group, and has already been registered as Japanese Patent No. 1738649. This device searches for an emergency signal caught by an omnidirectional antenna group with a plurality of directional antenna groups, and further searches for the source of the emergency signal with a rescue vehicle that was activated.

On the other hand, as a position detecting device using a satellite, a current position emergency notification device (Japanese Patent Laid-Open No. 5-20578) that automatically reports the current position from a vehicle that has caused an accident, and a navigation device using GPS (Japanese Patent Application Laid-Open No. 5-26679) has been filed.

[0004]

[Problems to be solved by the device]

 The conventional wide area rescue system has made it possible to quickly identify the source by activating multiple directional antenna groups and rescue vehicles even when the signal source is constantly moving. However, because signals are caught by multiple antenna groups installed on the ground, even if exploration is possible, accuracy will be improved under adverse conditions such as urban areas where tall buildings are forested and radio waves are reflected by buildings. And the exploration time is limited. Moreover, since it is necessary to install a large number of antenna groups, the construction cost and maintenance cost of the entire system must be high.

Further, since the GPS-based emergency notification device and the navigation device use GPS private radio waves, there is a disadvantage in that accuracy varies depending on the date and time of use. In other words, since there are cases where an accurate position can be specified and cases where a large error is included, the position where an emergency is specified is unreliable.

As satellites having different performance from GPS, there are known communication satellites using low-orbit satellites and geostationary satellites. This kind of satellite is used in place of an antenna, so to speak, and can transmit specific radio waves in mutually directions. Although it is possible to send position information using this type of satellite, since the position information specified using GPS is communicated at this time, the accuracy will also vary depending on the date and time of use.

As described above, since the position search using GPS does not have the same accuracy, a wide area rescue system that supports a 24-hour system needs more reliable position information.

Therefore, the present invention was created in order to solve the above-mentioned problems, has extremely high precision exploration performance, and is cheaper in construction cost and maintenance cost of the entire apparatus than the conventional system. The purpose is to provide a wide area rescue device.

[0017]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

The basic device of the present invention is a device for searching the source of the emergency signal 2 by using the GPS satellite P and the communication satellite Q together. The GPS satellite P is a military satellite of the United States and measures the position of the receiving side by receiving signals transmitted from a plurality of GPS satellites P.

On the other hand, the communication satellite Q is a satellite that transmits and receives radio waves from the ground and other satellites, and communicates specific radio waves in mutually directions. At this time, the communication satellite Q can measure the position of the communication satellite Q itself, the transmission position on the ground which the communication satellite Q receives, and the like by the signal of the GPS satellite P.

One of the embodiments of the present invention is that the communication satellite Q, which has received the emergency signal 2 from the transmitter 1, measures the source of the emergency signal 2 using the data of the communication satellite Q itself, and outputs the position information 6 as emergency. It is transmitted to the central information processing device 3 together with the signal 2 (see FIG. 1). The position information 6 is measured based on the satellite position data 6A received by the communication satellite Q from the GPS satellite P. In addition, the emergency signal 2 is planned to be an emergency signal 2 that uses an ID code. In addition to the simple SOS signal, the content that requires urgency, the sender's name, address, blood type, emergency contact information, etc. are required. Information is included. Then, the emergency signal 2 and the position information 6 are transferred via the central information processing device 3 to the individual information processing device 4 in charge of the area where the emergency signal 2 is transmitted. Further, the communication between the communication satellite Q and the central information processing unit 3 is usually via a relay station dedicated to the communication satellite Q, a network control center, a position calculation center, etc. The position information 6 is transmitted to the central information processing device 3 from the ground line.

The individual information processing device 4 causes the rescue vehicle 5 to be rushed to the source of the emergency signal 2 from the transferred information. The individual information processing device 4 is arranged in each region to build a network centered on the central information processing device 3. For example, the central information processing device 3 is provided in Tokyo and the individual information processing devices are provided in other prefectures. We are planning a nationwide network such as 4 In order to speed up the delivery of the rescue vehicle 5, a rescue vehicle distribution center (not shown) is provided between the individual information processing device 4 and the rescue vehicle 5, and the instruction of the individual information processing device 4 is given. It is also possible to have the rescue vehicle 5 rush through the rescue vehicle distribution center.

The rescue vehicle 5 searches for the transmission source by the position information 6 transmitted to the central information processing device 3 and the rescue vehicle position data 6B obtained by the GPS navigation 5A mounted on the rescue vehicle 5, Take action according to the content of the emergency signal 2. Further, by providing a transmitter / receiver in the transmitter 1, it is possible to enable mutual communication between the central information processing device 3 or the individual information processing device 4 and the sender. By performing mutual communication with the caller in this manner, added value can be increased, for example, relief can be provided at an early stage in the case of rescue of a mountaineer or the like.

At this time, in the individual information processing device 4 located closest to the transmission source, the correction value is detected by the correction device 10 that corrects the position information of the GPS satellite P, and the position information 6 of the transmitter 1 is accurately detected. Correcting the position information 6'and transmitting it to the rescue vehicle 5, it is possible to improve the accuracy of the search for the rescue vehicle 5. In this correction device 10, the individual information processing device 4 installed at a fixed position receives a signal from a GPS satellite P to obtain correction position data 6C. Then, the error between the previously confirmed latitude and longitude of the individual information processing device 4 and the latitude and longitude indicated by the correction position data 6C is confirmed, and this is used as the correction value. Therefore, it is desirable that the correction device 10 is not too far from the source of the emergency signal 2.

The correction device 10 shown in FIG. 2 uses a CPU 11, a map ROM 12, and a map display CRT 13 used in the individual information processing device 4.

That is, the CPU 11 receives the position information 6 {latitude N1 (t1), longitude E1 (t1), altitude H1 (t1)} sent from the transmitter 1 via the communication satellite Q. Next, the GPS receiver 4A of the individual information processing device 4 is requested to provide the correction position data 6C {latitude N2 (t2), longitude E2 (t2), altitude H2 (t2)}. At this time, the correct position data (latitude N0, longitude E0, altitude H0) of the place where the individual information processing device 4 is installed has been confirmed in advance. Then, this correct position data (latitude N0, longitude E0, altitude H0) and position data 6C for correction of the individual information processing device 4 obtained from the GPS receiver 4A {latitude N2 (t2), longitude E2 (t2), altitude Calculate the correction value (latitude ZN, longitude ZE, altitude ZH) from H2 (t2)}. The calculation formula is as shown in Equation 1.

[0026]

[Equation 1] The map ROM 12 uses the position information 6 {latitude N1 (t1), longitude E1 (t1), altitude E1 (t1)} of the transmitter 1 and the correction value (latitude ZN, longitude ZE, altitude ZH) to calculate the number 2 Accurate position information 6 '(latitude NM, longitude EM, altitude HM) of the transmitter 1 is calculated by the following formula.

[0027]

[Equation 2] That is, in this formula, {latitude N1 (t1), longitude E1 (t1), altitude H1 (t1)} is the position information 6 from the communication satellite Q at time t1. Further, {latitude N2 (t2), longitude E2 (t2), altitude H2 (t2)} is the correction position data 6C of the individual information processing device 4 obtained from the GPS receiver 4A at time t2. Further, (latitude N0, longitude E0, altitude H0) is the correct position data of the individual information processing device 4, which has been confirmed in advance. At this time, if the times t1 and t2 are almost the same, the accurate position information 6'of the transmitter 1 is obtained by the equation (3).

[0028]

[Equation 3] The map display CRT 13 displays the position of the transmitter 1 on the map based on the calculated accurate position information 6 '(latitude NM, longitude EM, altitude HM). Then, the individual information processing device 4 notifies the correction value by marking the accurate position on the monitor of the GPS navigation 5A of the rescue vehicle 5.

Further, another embodiment of the present invention includes a receiver 8 which receives the receiver position data 6D from the GPS satellite P (see FIG. 3). That is, instead of the transmitter 1 that transmits the emergency signal 2 in an emergency, a transmitter 9 that transmits the position information 6 and the emergency signal 2 is provided.

The transmitter 9 includes a receiver 8 which receives the receiver position data 6 D from the GPS satellite P, and the position information 6 is obtained by the receiver 8. The receiver 8 and the transmitter 9 may be mounted on a vehicle as well as carried by an individual. Then, the communication satellite Q receives the emergency signal 2 and the position information 6 and transmits them to the central information processing device 3. Therefore, the communication satellite Q used at this time does not need to have a receiver for receiving the GPS position information, and the position information of the transmitter 9 which has transmitted the emergency signal 2 by the communication satellite Q does not have to be specified. . As a result, various communication satellites Q such as low-orbit satellites and geostationary satellites can be used as the communication satellites Q. Further, the transmitter 9 and the receiver 8 are allowed to mutually communicate with the central information processing device 3 and the individual information processing device 4, thereby further increasing the added value thereof.

After that, the flow of the central information processing device 3, the individual information processing device 4, and the rescue vehicle 5 is the same as in the previous embodiment.

Further, the above-described correction device 10 may be provided in the individual information processing device 4 to correct the position information 6C and 6D of the GPS satellite P used by the receiver 8 and the rescue vehicle 5, respectively.
