Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention makes it possible to audio-visually reproduce the situation of a moving object and the scenery seen from the moving object based on position information and speed information of the moving object. The present invention relates to a monitoring device for a mobile object.

(Prior art) Conventionally, when monitoring the movement of moving objects such as railcars and robots moving within a factory at a monitoring center located in a remote location, position sensors installed on the moving path of the moving object and Sensor information such as the mounted speed sensor is transmitted to a monitoring location such as a center via communication means, and the monitoring location that receives this sensor information calculates the position of the moving object based on the sensor information.
Monitoring has been done by displaying on-site drawings displayed on a display such as RT, or by displaying text, audio, etc. - (Problem to be solved by the invention) However, in such conventional mobile object monitoring devices,
Since the status of a moving object is displayed using abstract information such as text, audio, or still images, monitoring of a moving object requires an expert who can judge the displayed content.
Errors tend to occur when judging the situation of a moving object.

In addition, the displayed information includes the scene where the moving object is located,
Since the situation was not reflected at all, there was a problem with the lack of a sense of reality and the inability to accurately judge the situation.

The present invention has been made in view of the above points, and it is possible to easily monitor the situation of a moving object accurately and realistically using realistic information such as more specific images and sounds that are suitable for the site. The purpose of the present invention is to provide a mobile body monitoring device that can be used to monitor mobile objects.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a sensor that detects the position, speed, etc. of a moving object, and an audio/visual system that uses the sensor information detected by the sensor to monitor the moving object. a database having a signal processing means for converting into information retrieval commands, and a storage medium storing audio/visual information for displaying images and sounds with a sense of presence equivalent to the situation of the moving object and the surrounding scene; A monitor means for displaying the audio/visual information read from the database, and a search command sent from the signal processing means are decoded to calculate an address on the storage medium of the database, and the address is designated by this address. and a control means for outputting the obtained audio/visual information to the monitor means to display the situation of the moving body in an artificial reality manner.

(Operation) By taking in the sensor information detected by the sensor into the signal processing means, a command for retrieving audio/visual information that displays the situation and scene of the moving body at that time is generated and output to the control means. Along with this, the control means is configured to perform audio/audio processing according to the search command.
Visual information is retrieved from a database and output to a monitor means to display the situation of a moving body with images and sounds that give a sense of artificial reality. Therefore, by looking at the monitor means, the situation of the moving body can be easily monitored from a remote location accurately and in a realistic manner.

(Example) Embodiments of the present invention will be described below with reference to FIG.

Fig. 1 shows an embodiment in which the monitoring device of the present invention is applied to a rail car, in which 1 is a track laid endlessly in a factory, etc., and 2 is a rail car that automatically runs on the track 1 for transporting cargo, etc. It is an orbital car.

A speed sensor 3 is attached to the rail car 2 to detect its running speed. Further, a plurality of position sensors 4 are arranged along the track 1 to detect the running position of the rail car 2.

The speed sensor 3 is connected to a counter circuit 5 via a power supply line or a signal line (both not shown) laid along the track 1.
The signal (pulse signal) generated from the speed sensor 3 according to the running speed of the railcar 2 is counted, and the count value is input to a signal processing device 6 consisting of a computer.

Further, each position sensor 4 is connected to a signal processing device 6 via a sensor input circuit 7 that detects future signals.

The signal processing device 6 calculates a database search command based on the position information from each speed sensor 4 and the speed information taken in from the counter circuit 5.

The signal processing device 6 includes a network termination device 8 and a digital subscriber line 9.

When the rail car 2 travels on the track I in a state where it is linked via the digital subscriber l119 and the digital subscriber l119, the accompanying signal S1 from the speed sensor 3 is input to the counter circuit 5 and counted sequentially. Further, a position signal S2 outputted every time each position sensor 4 detects a railcar 2 is input to the sensor input circuit 7, converted into a digital signal, and inputted to the signal processing device 6 manually.

The signal processing device 6 issues a command for searching the image database based on the device data constituted by the sensor input circuit 7 and the speed data taken in from the counter circuit 5 at predetermined time intervals (every processing cycle of the signal processing device 6). generate. This command is transmitted to the sensor-side control device 12 through the linked transmission path.

The control device 12 decodes the received search command,
Then, by referring to the data directory of the AV database 13, the address of the record on the storage device 9, for example, a laser disk drive is calculated. As a result, the data at the designated address on the laser disk is read out in units of memory and output to the monitor device 14.
