Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is applicable to unmanned automatic monitoring of production facilities with poor atmospheric conditions such as those around chemical plants and inside various factories, as well as various underground passages such as sewers and traffic lanes. This invention relates to a self-propelled monitoring device that can be used for work.

(Prior art and its problems) It is necessary to periodically inspect various production facilities and facilities in underground passages that have poor atmospheric conditions as described above, or inspect the composition and concentration of atmospheric gases. The conventional method of manually performing such work is not only inefficient, but also poses a very high risk of personal injury due to unfavorable atmospheric gas conditions. In addition, it is necessary to inspect the road surface condition for automobile tunnels to check for fallen objects, and for railway tunnels, the track condition must be periodically inspected, but in both cases. Workers need to pass through the tunnel, which is not only dangerous but may also interfere with the smooth running of other passing vehicles.

(Means for Solving the Problems) The present invention proposes a self-propelled monitoring device that is useful for solving the above-mentioned problems. In addition, a train equipped with a battery for power supply to a motor connected in conjunction with the drive wheels is equipped with a sensor such as a detector or a television camera that detects the temperature, composition, etc. of the atmosphere, and the train is equipped with a sensor such as a detector or a television camera that detects the temperature, composition, etc. of the atmosphere, and the train is equipped with a sensor such as a detector or a television camera that detects the temperature, composition, etc. of the atmosphere. The present invention is characterized in that the situation can be monitored using the sensor.

(Embodiment) An embodiment of the present invention will be described below based on the attached illustrative drawings. Reference numeral 1 denotes a guide rail installed on the ceiling of an underground passage, and a hanging member 2 It is suspended from the underground passage ceiling surface 3. 4 is a train suspended on the guide rail 1, with driving wheels 5
The self-propelled trolley 10 is composed of a driving trolley 7 having a motor 6 and a motor 6 interlocked therewith, a driven trolley 9 having idle wheels 8, and a self-propelled trolley 10 suspended by both trolleys 7.9. is equipped with a control device and a battery 11 that supplies power to the motor 6 via the control device.

Reference numeral 12 denotes a surveillance television camera attached to the front end of the self-propelled trolley 10 of the train 4, and is mounted on a lifting platform 14 that is movably supported by a multi-stage stretchable body 13 that extends and contracts vertically. It is mounted via left and right swing drive means 15. 16 is the monitoring television camera 12
17 is a telescopic driving means for the multi-stage telescopic body 13.

Reference numerals 18 and 19 are bumpers provided at the front and rear of the train 4, and reference numeral 20 and 21 are movable pieces for detecting obstacles attached to the bumpers 18 and 19. This movable piece 20.21 swings backward against the urging force by contact with the obstacle before the bumper 18.19 collides with the obstacle, and activates the detection switch. By operating the switch, power supply to the motor 6 is cut off and the train 4 is automatically stopped.

The monitoring television camera 12, the swinging drive means 1
5. Photographing area illumination light 16 and telescopic drive means 17
Power is also supplied from the battery 11 to the self-propelled vehicle 10 via a control device mounted on the self-propelled trolley 10.

To explain the method of monitoring inside an underground passage using the self-propelled monitoring device configured as described above, the drive wheels 5 are driven to rotate and the train 4 is moved along the guide rail 1 from the start to the end of the running route at a constant speed. The vehicle is made to run continuously at a high speed, and at the same time, a light 16 is turned on and the inside of the underground passage is continuously photographed by a monitoring television camera 12. At this time, the swing driving means 15 and the telescopic driving means 17 are driven according to a preset program, and the monitoring television camera 12
By automatically changing the height and direction of the light 16, it is possible to photograph the entire area in the underground passage that requires monitoring as the train 4 travels.

The video taken by the surveillance television camera 12 is recorded by a recording device mounted on the train 4, and after the train 4 reaches a predetermined location such as the end of the running route, the video recording medium is taken out and played back at an appropriate location. You can check the situation inside the underground passage. Of course, the surveillance television camera 1
The images taken in step 2 are sent via radio waves from the running train 4 to a monitor television at a monitoring center on the ground side, etc., so that the situation inside the underpass can be monitored in real time on this monitor television, and if necessary, It can also be configured to record the video.

It is also possible to automatically stop the train 4 one after another at a plurality of preset stopping rooms along its travel route, and to have the monitoring television camera 12 photograph the inside of the underground passage only at each of the train stopping points. It is.

Furthermore, the control of stopping and starting the train 4 may be configured to be performed manually from a ground-side monitoring center or the like while viewing images from the monitoring television camera 12. , the light 16, the swing drive means 15, and the telescopic drive means 17 can also be controlled manually from a monitoring center on the ground, etc., so that shooting can be freely controlled, and the density can be increased even further. High-level monitoring work can be performed. In this way, when remotely controlling the train 4, the monitoring television camera 12, and the equipment attached thereto, it is desirable to use a wireless system using radio waves or the like.

In the above embodiment, the television camera 12, which is an image sensor, was used as the monitoring sensor, but any sensor may be used depending on the object to be monitored.For example,
When monitoring the presence or absence of toxic gas generation in underground passages,
A sensor for detecting the toxic gas may be used, and a sensor for temperature detection may be used to monitor abnormal heat generation. Of course, multiple sensors can also be used in combination.

Furthermore, although a monitoring sensor is attached to the self-propelled trolley 10, when the monitoring television camera 12 is used as a sensor as in the above embodiment, the entire monitoring means including the attached equipment becomes relatively large. The monitoring means can also be mounted on a towed truck that is towed by the self-propelled truck 10.

Furthermore, although a suspended mole rail type train is used as the train 4, the present invention is not limited to this.

(Operations and Effects of the Invention) As described above, according to the self-propelled monitoring device of the present invention, the guide rail installed in the monitoring work place with poor atmospheric conditions can be used without the need for the monitoring worker to enter the monitoring work place. By simply driving the train along the road, the necessary inspection and monitoring work can be performed remotely using the sensors attached to the JFQ car, eliminating the risk of workers encountering danger at the monitoring work site. Therefore, it is also possible to perform monitoring work easily and safely in narrow spaces where it is difficult for workers to enter.

Moreover, since it uses a battery-powered self-propelled calculator, all that is needed is a guide rail installed at the monitoring location, which reduces the risk of damage to the power supply line compared to the case where the power supply line must be stretched. There is a risk that the train will be unable to run,
There is no fear that flammable gas accumulated in an underground passage or the like will catch fire and explode due to sparks generated by sliding contact between the power supply line and the collector on the train side.

When the monitoring device of the present invention is used as a monitoring device for a long traffic road, etc., it is not used for regular monitoring work on the said road, but for collecting various information from the accident site when an accident occurs. It can also be used for.
