Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to equipment for remote centralized monitoring using a television camera.

Conventionally, a large number of television cameras were installed at fixed positions, but since the field of view of the television cameras is limited, the duty to monitor a wide area (normally, in this case, a trolley equipped with a television camera is required). (hereinafter referred to as "patrol operations") and on-site monitoring operations (hereinafter referred to as "attendance operations") that involve monitoring from a fixed location.
If there are multiple monitoring locations and the monitoring locations that are the focus of monitoring change over time, this would require an extremely large number of television cameras, making it difficult to implement from an economic standpoint. had the disadvantage that it could not be applied.

The object of the present invention is to provide equipment that can simultaneously carry out patrol work and witness work under remote centralized monitoring using a television camera, even if the work involves patrolling a wide area or witnessing work whose location is subject to change. The aim is to be able to provide this at a cost low enough for practical use.

A single-track track is provided along the patrol route according to the present invention, a television camera is provided on a self-propelled trolley along the single-track track, and a remote control panel of the trolley and a monitor TV for the TV camera are installed at a remote central monitoring station. A characteristic configuration of the monitoring equipment is that a plurality of the bogies are arranged on the single-track track, and when a following bogie collides with a stopped bogie, a starting operation is performed to start the bogie in the moving direction of the following bogie. and a stop operation tool that stops the moving cart when the moving cart collides with the preceding cart,
Its effects are as follows.

In other words, during monitoring, when performing patrol work or witnessing work, the trolleys are moved or stopped, and when these tasks are performed simultaneously, some of the trolleys out of multiple trolleys are moved in advance. If the following bogies are placed in the place where each witness monitoring is required and the following bogies are started one after another with respect to this group of preceding bogies, the starting operation tool and the stop operation tool provided on each bogie will allow the The tasks are exchanged between the moving trolley and the following trolley (however, in patrol operations, the monitoring locations differ depending on the front and back positions of the route), so that the moving trolley can perform patrol operations and the stopped trolley can perform witnessing operations at the same time. I can do it.

As a result, we have achieved reductions in the number of personnel needed for patrol work in wide areas and witness work where locations tend to change, as well as a reduction in the workload and improved safety for patrol work in areas that require a lot of climbing and descending. and,
As for the equipment, the moving configuration of the TV camera using a combination of single-track tracks and trolleys is sufficient for practical use, compared to installing a large number of fixed TV cameras, and compared to installing double-track tracks. This can be done at low cost, and overall,
Good monitoring has become economically advantageous.

Next, examples will be shown.

As shown in Figure 1, a single monorail 1 is installed in a loop along the patrol route, and the required number of self-propelled trolleys 2a, 2b, 2c, and 2d can be sent from the terminal 3 to the monorail 1. It is designed so that it can be returned to Terminal 3. Further, a remote control panel 4 for remotely controlling the trolleys 2a to 2d, a monitor television 5 for showing images sent from the television cameras of the trolleys 2a to 2d, and the like are installed at a remote central monitoring station 6.

A communication circuit unit 15 performs the transmission of information from 4 and the like.

A transmitter 16 that notifies the following truck 2 of its approach, and a receiver 17 that decelerates the truck 2 based on the signal from the transmitter 16 of the leading truck 2.

A bumper/stop operating tool 19 that automatically stops the trolley 2 when it hits the bumper/start operating tool 18 of the leading trolley 2, and a bumper/stop operating tool 19 that automatically stops the trolley 2 by hitting the bumper/start operating tool 19 of the following trolley 2.
A bumper/start operation tool 18 that automatically starts the vehicle.

A storage battery 20 as a power source for everything, and a charging terminal 21 for it.

Next, a monitoring method using the above-mentioned monitoring equipment will be explained.

As shown in FIG. 1, trolleys 2a, 2b are sent to locations A, B, and C, such as construction sites, where on-site monitoring is required, by monorail 1 from terminal 3 and by operation from remote central monitoring station 6. , 2c are moved, and by using the television cameras 10 and the like of the stopped carts 2a, 2b, 2c, witnessing operations are performed from a remote central monitoring station 6 for all witnessing monitoring locations A, B, and C.

In addition, when patrol work is necessary, the trolley 2 sent out from the terminal 3 is moved by the monorail 1 and operated from the remote central monitoring station 6 until it returns to the terminal 3, and the trolley 2 that is being moved is moved. Patrolling the entire patrol route is carried out from a remote central monitoring station using a television camera 10 or the like.

Here, when performing patrol work and witnessing work at the same time, first move each trolley 2a, 2b, 2c to each witnessing monitoring location A, B, C, as explained in the above-mentioned witnessing work, and then A new trolley 2 is sent out from terminal 3 and headed for witness monitoring location A. In this way, each trolley 2,
Due to the functions of the bumper/start operating tool 18 and the bumper/stop operating tool 19 provided in 2a, 2b, and 2c,
The leading trolley and the following trolley sequentially replace each other, and at the same time, the moving trolley performs patrol work and the stopped trolley performs witnessing work.

The trolley 2, which has returned to the terminal 3 after completing the witnessing work and patrolling work, is charged by the charging device 22 at the terminal 3, put on standby, and sent out again.

Next, communication equipment between the remote central monitoring station 6 and the trolley 2 will be explained with reference to FIG.

Based on the information from the position detector 9, the computer 23 of the remote central monitoring station 6 confirms the position of the trolley 2, and the direction of the parabolic antenna 25 of the fixed station 24 and the parabolic antenna 13 of the trolley 2 is determined by the command from the computer 23. are adjusted so that they face each other, so that communication between the remote central monitoring station 6 and the trolley 2 can be carried out effectively.

Next, another example will be described.

Using the monorail 1 has the advantage that the track can be formed easily and inexpensively, and that it can easily handle sudden climbs and descents and turns. The track configuration can be changed appropriately, such as improvement, and in short, the single track track 1 is sufficient.

Make single track 1 into a loop and connect terminal 3 to 1
Having separate locations has the advantage of making it easier to manage the trolleys 2, especially when the trolleys 2 are self-propelled with storage batteries 20. An operation method may be adopted in which the trolley 2 is sent out from the terminal 3 on the opposite side for each job. In addition, loop-shaped single track 1
Terminals 3 equipped with charging devices 22 and the like may be arranged at a plurality of locations to prevent the storage battery 20 of the trolley 2 from rising.

If the trolley 2 is of a type that uses the storage battery 20 as its power source, it can prevent accidents such as ignition of flammable gas and is superior in safety. Appropriate changes can be made in the power supply configuration, such as making it a wired type that accepts electric power.

The monitoring structure attached to the trolley 2 only needs to include at least the television camera 10, and may also include various monitoring structures depending on the place to be monitored.

Communication between the remote centralized monitoring station 6 and the bogie 2 is preferably done by wireless, and in that case, the number and arrangement of the fixed stations 24 are such that no matter where the bogie 2 is located on the single-track track 1, The parabolic antenna 25 of the fixed station 24 may be used for communication between the fixed station 24 and the remote central monitoring station 6, or between the fixed stations 24, either by wireless or by wire. good.
