Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention measures data relating to the range of movement and habitat of wild animals such as deer, which inhabit a wide range of forests and the like, and data relating to the travel route of a moving vehicle or the like. And a moving body monitoring system for monitoring a moving body based on measurement data of a moving body and the like.

[0002]

2. Description of the Related Art Conventionally, a moving position and a path of a moving body (for example, an animal or a moving vehicle such as a commercial vehicle) that moves irregularly within a predetermined area are measured, and the moving body is determined based on measurement data. A mobile monitoring system for monitoring has been proposed. In these mobile body monitoring systems, generally, each mobile body and a predetermined monitoring center station for monitoring the mobile body transmit and receive position information by wireless communication.

[0003] For example, when investigating the range of action and habitat of wild animals such as deer living in a wide range of forests and the like, a transmitter for transmitting a radio signal of a predetermined frequency to a captured wild animal is attached. In general, a method of estimating the position of the wild animal by simultaneously detecting the direction of the signal using a direction finder located at a plurality of predetermined fixed stations is known. However, in the above method, since the radio signal must be constantly transmitted, the power consumption of the transmitter is large, and the life of the battery that supplies the operating power to the transmitter is reduced in a short time. For this reason, conventionally, the position estimation by the transmitter can be performed only for a short period of time, and when the transmission signal is no longer received, the wild animal is captured again and the battery is replaced. Therefore, there is a problem in that the replacement work is extremely troublesome and an efficient investigation cannot be performed.

Further, for example, in the case of a monitoring system that measures a moving position and a route of a moving vehicle and performs operation management based on the measured data, a moving object in a wide range (for example, a radius of several 10 km) is used. In order to perform position measurement, wireless communication with high power output is used, so that a vehicle-mounted wireless device and a controller are increased in size, and it is necessary to supply power to the wireless device from a vehicle-mounted battery. For this,
When configuring a monitoring system as described above, it is difficult to secure a place to install a wireless device or controller to be attached to a moving vehicle, or it is troublesome to modify the vehicle for installation and connect the power cable. Problems arise.

On the other hand, as a method for solving such a problem in the mobile monitoring system, there is no concrete method conventionally proposed, but it is conceivable to apply a method used in other fields. . For example, JP-A-6-12
Japanese Patent No. 3767 discloses monitoring, rescue and recovery of persons without specific abilities (toddlers, senile dementia, sick persons, victims, etc.) and articles or living things (stolen vehicles, lost items, pets). There is disclosed a position search device for the purpose. According to the publication, a pager (usually receives a predetermined radio frequency signal via a built-in antenna, and amplifies, detects, demodulates, shapes, etc. the received signal to a person or an article whose position is to be searched, This received data and I stored in advance in the internal storage
It has a function of comparing the D number to output an ID signal indicating whether or not there is a call, a control unit, a radio transmitter, and a GPS (so-called Global Positioni).
ng System) A position search device including a receiver and a power supply unit is attached. The control unit receives the output signal (ID signal) of the pager and sequentially activates the GPS receiver and the wireless transmitter. The GPS receiver receives radio waves from GPS satellites. It measures its own position, and the radio transmitter transmits the measurement data of the GPS receiver on radio waves.
Then, based on the ID signal, the control unit controls the GPS receiver and the wireless transmitter to intermittently supply the voltage from the power supply unit (battery) of each GPS receiver and the wireless transmitter for a predetermined time. doing.

[0006] According to the above technique, the power consumption of the GPS receiver and the radio transmitter is reduced, so that the battery can be used for a long time. In addition, since a battery is used and the device can be relatively miniaturized, the number of modifications when mounted on a mobile vehicle is reduced.

[0007]

However, the following problems occur in the moving object monitoring system based on the measured position data by the position searching apparatus disclosed in the conventional Japanese Patent Application Laid-Open No. 6-123767. (1) Usually, a moving body (wild animal, moving vehicle, or the like) has a very wide moving range. Therefore, when the location information of the mobile unit should be collected from a predetermined caller (a station that calls a pager and corresponds to a monitoring center station for collecting data in the present invention) (for example, at a predetermined cycle time), There is no guarantee that the mobile is always within the communicable range between the caller and the wireless transmitter of the location device. For this reason, it is impossible to collect position information until the moving object enters the communicable range. This also gives
Since the position information of the moving object at every predetermined time cannot be collected, the moving position and route (corresponding to the range of action and habitat in the case of a wild animal) cannot be accurately measured.

[0008] (2) When using wireless communication that outputs a strong radio wave such that the communicable distance between the caller (monitoring center station) and the wireless transmitter of the position search device is increased, this communication is used. The power consumption for this increases. For this reason, similarly to the above, the measurement period of the attached battery is shortened and the measurement efficiency is reduced, or if a large capacity battery is used, the position search device itself becomes large, and In addition, it is very difficult to attach to a moving body.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a moving object monitoring system which can be reduced in weight and size and can measure an accurate moving path of the moving object. .

[0010]

Means for Solving the Problems, Functions and Effects In order to achieve the above object, the invention according to claim 1 measures a moving position of a moving body and moves the moving body based on the measured position data. In a mobile monitoring system for monitoring, a GPS for obtaining at least the latitude and longitude of the current position or an altitude based on data received from a GPS satellite S
A receiver 12, a nonvolatile memory 18 in which the obtained measurement position data is stored, a radio device 15 for transmitting and receiving data wirelessly, and a measurement device obtained by the GPS receiver 12 for each predetermined cycle time T1. The position data is input and stored in the non-volatile memory 18 in a time-series manner. When communication via the wireless device 15 is possible, the measured position data stored in the non-volatile memory 18 is stored in the non-volatile memory 18. , The GPS receiver 12, the non-volatile memory 18, the wireless device 15, and the controller 11
Device 1 including a battery 17 for supplying operating power to the GPS device 1
0 is attached to the mobile body, and when communication with the GPS device 10 of the mobile body via the wireless device 15 is possible, the monitoring center station 20 that performs the wireless communication and receives the measurement position data all at once. Are provided in a predetermined vicinity area covering the moving range of the moving body.

According to the first aspect of the present invention, the controller of the GPS device attached to the mobile body obtains the current position by the GPS receiver every predetermined period of time, and converts the obtained measured position data in time series. When the wireless communication with the monitoring center station is possible (that is, when the moving object is within the communication range from the monitoring center station), the stored measurement position data is stored in the non-volatile memory. The data is transmitted to the monitoring center station all at once via a wireless communication device. by this,
Even if the distance between the GPS device of each mobile unit and the monitoring center station is not within the range in which wireless communication is possible, the position data cannot be measured during the communication disabled period unlike the conventional method.
The moving position of the moving body at every predetermined time can be reliably measured. Therefore, based on the measured position data, the continuous moving path of the moving object in time can be plotted on the map,
Accurate position monitoring of the moving object becomes possible. Also, if the mobile object is not within the communication range,
Even when wireless communication cannot be performed for a predetermined period of time, such as when the voltage drops due to the life of the battery in the GPS device, or when wireless communication becomes impossible halfway, the measurement data is stored in the nonvolatile memory. So that GP
Data can be collected by removing the controller from the moving body to which the S device is attached and reading out the data in the nonvolatile memory. As a result, the possibility of data measurement is not affected by uncertain factors such as the moving range of the moving body, and the measurement can be performed reliably and at predetermined time intervals. In addition, latitude and longitude by GPS,
Alternatively, if necessary, the position data of the altitude is measured, so that the position data can be measured with high accuracy, and the accuracy of monitoring the position of the moving body is improved.

According to a second aspect of the present invention, in the mobile object monitoring system according to the first aspect, the mobile object is a wild animal.

According to the second aspect of the present invention, when the moving object is a wild animal, the action position data within a predetermined moving range (ie, action range) of the wild animal is accurately measured. Based on the data, it is possible to accurately observe the ecology of wild animals. That is, as described in the first aspect, even if a wild animal (a deer or the like) is not within a communication range with the monitoring center station and polling is not received, the GPS device attached to the wild animal can be used. It is possible to reliably measure the position data at every predetermined cycle time. Therefore, it is possible to perform ecological observation with high accuracy by measuring the behavior position and the habitat state (habitat environment) of the wild animal. Also, if the wildlife does not fall within the communicable range, or if the voltage drops due to the life of the battery in the GPS device, wireless communication cannot be performed for a predetermined period, or Even if wireless communication is disabled, the measurement data is stored in the non-volatile memory. Therefore, the wild animal to which the GPS device is attached is captured and the data in the non-volatile memory is read to collect data. It becomes possible. As a result, the availability of data measurement is not affected by uncertain factors such as the range of action of the wild animal, and measurement can be performed reliably and at predetermined time intervals. In addition, since latitude and longitude or even higher altitude position data is measured by GPS, position data can be measured with high accuracy, and the accuracy of ecological observation is improved.

According to a third aspect of the present invention, in the moving object monitoring system according to the first aspect, the moving object is a moving vehicle 5.
It is characterized by being 0.

According to the third aspect of the invention, when the moving body is a moving vehicle (construction machine, industrial vehicle, business vehicle, or the like), the moving position data within a predetermined moving range of the moving vehicle is accurate. Therefore, the operation management of the moving vehicle can be accurately performed based on the measured position data. That is, since the moving route of each moving vehicle can be accurately tracked, it is possible to manage the suspension of the vehicle and the dispatch of vehicles while checking the operating state of the entire vehicle based on the operation results of each moving vehicle. Alternatively, the operating state of each moving vehicle can be estimated, and the timing of the periodic inspection can be determined not only based on the operating time but also comprehensively. As a result, fine monitoring of the moving vehicle can be performed, so that the management of the moving vehicle is facilitated. In addition, by adding this GPS device to a normally used mobile vehicle, it can be operated independently of the originally installed on-board battery, so it can be moved without major modification. The vehicle can be monitored, and the moving position during this time can be monitored even when the driving key switch is turned off. Therefore, for example, even when a moving vehicle is stolen while suspended, the position data along the transport route is automatically measured and stored, so that when searching for a stolen vehicle, a ground mobile station or By helicopter search station,
By polling the above-mentioned potentially transported area, the final transportation location can be easily searched. At this time, the GPS device main body and the GPS antenna attached to the moving vehicle are lightweight and miniaturized, and the normal on-board battery and the power cable are not connected. GPS devices are hard to find.

According to the fourth aspect of the present invention, since the SS radio is used for the communication between the GPS device and the monitoring center station, the radio and the antenna can be reduced in weight and size. Therefore, the wireless device and the wireless antenna incorporated in the GPS device can be reduced in weight and size, and the entire GPS device can be reduced in size. This makes it possible to configure a GPS device that can be attached to the neck or the like of the moving object and that can perform highly accurate position measurement by GPS, so that the ecology of the moving object can be closely observed.

According to the fifth aspect of the present invention, the wireless communication between the controller of the GPS device and the monitoring center station is performed at predetermined time intervals only when communication is possible. Here, whether communication is possible or not can be determined based on whether polling has been received from the monitoring center station. Therefore,
Power supply to the GPS receiver, the wireless device, the controller, and the like can be stopped except when the above-described processes are performed at every predetermined cycle, so that the battery life of the GPS device can be extended. . As a result, the GPS device can be operated for a predetermined period by a small battery such as a lithium battery, so that the size and weight can be reduced so that the GPS device can be attached to a moving object.

Further, the controller 11 stores the image data from the small CCD camera 31 in a predetermined area of the nonvolatile memory 18 in a time-series manner during a predetermined time T3 during the periodic processing. Then, it is determined whether or not polling is received from the monitoring center station 20 via the modem 14 and the wireless device 15 during a predetermined time T2 after the start of this periodic processing.

On the other hand, the monitoring center station 20 always keeps the GPS device 1 attached to each wild animal (here, a deer).
Polling is performed by sequentially transmitting ID codes of 0. Regardless of whether the monitoring center station 20 is a fixed station 20a, a ground mobile station 20b, or a helicopter search station 20c, the distance between the monitoring center station 20 and each GPS device 10 is within a predetermined communicable distance. Until the polling, the GPS device 10 does not receive the polling.
No. 1 merely stores the current measurement position data and image data for each predetermined time T1 in time series during this period. Then, when the GPS device 10 comes within the communicable range by the deer's action, the controller 11 receives the polling and the received data at this time is its own I / O.
It is determined whether it matches the D code. When the received data coincides with its own ID code, it immediately transmits the stored measurement position data and image data to the monitoring center station 20 via the wireless device 15. At this time, subsequent data is transmitted simultaneously in chronological order from each data transmitted when the previous communication was possible.

As described above, according to the present invention, the position data measured by the GPS device and the image data of the small CCD camera 31 are stored in the flash memory in a time-series manner every predetermined period of time. The center bureau and each individual wild animal (ie, the GP attached to each individual)
S device) is not within the range in which the wireless communication is possible, the position data during the communication disabled period does not become unmeasurable as in the conventional method, and the action position of the wild animal at every predetermined time is surely ensured. And the habitat (habitat environment) can be measured and observed, respectively. Therefore, the temporally continuous behavior of the wild animal can be plotted on a map and printed out based on the measurement data, so that accurate ecology observation can be performed.

Normally, when a wild animal comes within the communicable range, the stored (stored) data is transmitted and received at the same time between each GPS device and the monitoring center station. If the wildlife never enters the communicable range, the voltage drops due to the life of the battery 17 in the GPS device, and the wireless communication cannot be performed once, or communication becomes impossible in the middle. Even if
Since the data is stored in the flash memory, the data can be collected by capturing the wild animal to which the GPS device is attached and reading out the data in the flash memory. As a result, the possibility of data measurement is not affected by uncertain factors such as the range of action of the wild animal, and the measurement can be reliably performed.

Since the measured position data is the latitude, longitude and altitude data obtained by GPS, accurate position data can be measured, and the accuracy of ecological observation is improved. Furthermore, if image data is collected simultaneously with this measurement data,
More detailed behaviors and eating habits can be observed, and detailed observation is possible.

Since the communication between the GPS device and the monitoring center station uses low power and high frequency band radio such as SS radio, the radio and radio antenna for this purpose are reduced in weight and size. As well as GP
The S device can be constituted by a power saving circuit. Further, in the GPS device, reception from the GPS satellite S, and
Since the wireless communication with the monitoring center station is performed for a predetermined period of time every predetermined period, the battery life can be extended. Therefore, the GPS device can be reduced in weight and size so that it can be attached to the neck of a wild animal, etc., and can be operated for a predetermined period by a small-capacity small battery. To observe the ecology of wild animals.

In addition, by installing fixed stations at a predetermined number of locations within a predetermined vicinity area covering the wild animal's range of action as a monitoring center station, when a wild animal approaches within a predetermined distance of this monitoring center station, Since the measurement data of each GPS device is automatically transmitted to the monitoring center station, it is easy to collect the measurement data. Further, when the measurement data received and stored by the monitoring center station is collected manually, for example, since the installation location of the monitoring center station is known in advance, it is possible to head to the installation location without hesitation, Collection work becomes very easy.

When the monitoring center station is mounted on a vehicle movable on the ground in the predetermined vicinity area and installed, when collecting measurement data stored in each GPS device, the It is possible to move directly to the vicinity of a place where the user is likely to be acting. Therefore, the measurement data can be reliably collected, and the collection work can be performed very easily.

Further, when the monitoring center station is mounted on a helicopter flying in the predetermined vicinity area and installed, a wild animal is acting when it is desired to collect measurement data stored in each GPS device. Since it is possible to approach directly to the vicinity of such a place from the air, it is possible to collect data even in a place where it is difficult for a vehicle or a person to approach, for example. Therefore, the measurement position data can be collected reliably and in a short time, and the collection work becomes very easy.

The wireless antenna 26 of the monitoring center station 20 and the wireless device 24 are selected and used, and the connectors 29a and 29a for directly connecting the wireless antenna 26 and the wireless device 24 without using a connection cable. 29
b. As a result, a decrease in output can be suppressed, so that the communicable distance can be extended even in low-power communication. As a result, in wireless communication for data collection from the monitoring center station 20, noise resistance is improved,
Data collection can be performed stably.

Next, another application example of the moving object monitoring system according to the present invention will be described with reference to FIG. The present embodiment measures a moving route of a moving vehicle 50 such as a construction machine, an industrial vehicle, or a commercial vehicle (for example, a bus or a taxi), and monitors the operation of the moving vehicle based on the measurement data. It is. FIG. 7 shows an example in which the GPS device 10 of the mobile monitoring system is attached to a hydraulic excavator 50a as an example of the moving vehicle 50. In addition,
In the figure, the same components as those described in the above embodiment are denoted by the same reference numerals, and description thereof will be omitted. In the figure, a hydraulic excavator 50a includes a lower traveling body 51 having a pair of right and left crawlers and other traveling parts, an upper revolving body 52 pivotably provided on the lower traveling body 51, and a front of the upper revolving body 52. A work machine 53 is provided in the section so as to be swingable.

A predetermined position of the vehicle body of the moving vehicle 50 (here, the upper part of the upper swing body 52 of the hydraulic excavator 50a).
The GPS device body 10a of the GPS device 10 and the GPS
An antenna 13 is provided, and the GPS device main body 1 is provided.
0a is on the inner side of the rear upper panel 54 of the upper swing body 52, and the GPS antenna 13 is
It is attached to the outer surface side. The outside of the GPS antenna 13 is covered with a plastic cover 55.

Here, the configuration of the GPS device main body 10a is as follows.
It is assumed that it is the same as that shown in the block diagram of FIG. However, the small CCD camera 31 may be provided if necessary.

The monitoring center station 20 has the same configuration as that shown in the block diagram of FIG.
As for the method of installing the monitoring center station 20, the fixed station 20a and the terrestrial mobile station 2 are set in the same manner as in the first embodiment.
0b or a helicopter search station 20c can be provided. A predetermined number of these monitoring center stations 20 are provided within a range covering a predetermined area where a mobile vehicle normally moves and operates.

According to the above configuration, the operation power is supplied to the controller 11 of the GPS device 10 for the predetermined period T2 for each predetermined period T1. At this time, the controller 11 controls the moving vehicle 5
The current position of 0 is measured via the GPS receiver 12, and the measured position data is stored in the nonvolatile memory 18 in time series. When the polling from the predetermined monitoring center station 20 is received during the predetermined time T2,
The measurement position data stored in the non-volatile memory 18 is transmitted to the monitoring center station 20 via the wireless device 15. As a result, the position data of the moving vehicle 50 at predetermined time intervals is received by the monitoring center station 20 and stored in the predetermined storage device 22. Furthermore, if the mobile vehicle 50 is longer than the distance at which the mobile device 50 can communicate with the
If you are away from, the wireless communication is not performed,
Only the process of storing the measurement position data in the nonvolatile memory 18 is performed. The moving vehicle is located at the monitoring center station 20.
When it moves within the communicable range with the mobile station, the measurement position data stored since the previous wireless communication is transmitted all at once.

From the above, the moving position of the moving vehicle 50 at every predetermined time is accurately measured and displayed on the display at the monitoring center station 20 in chronological order, or on a predetermined map covering the operating range. Can be plotted. Therefore, since the moving route of each moving vehicle 50 can be accurately tracked, it is possible to manage the suspension or dispatch of vehicles while checking the operating state of the entire vehicle based on the operation results of each moving vehicle. Alternatively, the operating state of each moving vehicle can be estimated, and the timing of the periodic inspection can be determined not only based on the operating time but also comprehensively. As a result, fine monitoring of the moving vehicle can be performed, so that the management of the moving vehicle is facilitated.

Further, the moving vehicle 50 which is normally used includes

Monitoring such as operation management becomes possible. Further, even if the operation key switch is turned off, the movement position during this time can be monitored. Therefore, for example, even when a moving vehicle is stolen during suspension, the position data along the transport route is automatically measured and stored, so that when searching for a stolen vehicle, the ground mobile station 20 b The helicopter search station 20c polls the above-mentioned area where there is a possibility of being transported, thereby making it possible to easily search for the final transport location. At this time, the GPS device main body 10a and the G
Since the PS antenna 13 is lightweight and small, and the power cable is not connected to the usual vehicle-mounted battery, the GPS device 10 is hard to be found by setting the mounting position to an appropriate position so as to be difficult to understand. .

In the above embodiment, the GPS
Is used to measure the latitude, longitude, and altitude, but the present invention is not limited to this, and only the latitude and longitude may be measured. Also in this case, since the accurate position can be plotted on the map, the moving route and the moving range can be measured with high accuracy.
