Description

Detailed Description of the Invention The present invention is applicable to patrol operations that monitor while moving along a patrol route (patrol monitoring operations) and witness operations that continuously monitor monitoring locations such as construction sites from fixed points (attendance monitoring operations). ).

Conventional monitoring methods include (a) a method in which workers patrol the site, (b) a method in which workers attend the monitoring location and conduct witness work, and (c) a method in which a television camera is installed at a fixed location. One of the methods was remote monitoring using a monitor TV.

The method (b) above has the disadvantage that it requires a lot of labor and manpower for patrolling, especially in wide areas or areas with many stairs.
Method (3) requires a large number of personnel when there are many monitoring locations, and method (C) above has a limited field of view for the television camera, so patrol operations and monitoring locations are subject to change. It was practically inapplicable to witness operations.

The purpose of the present invention is to be able to carry out patrol work with a small number of personnel and with little effort even in a wide area or in an area where there are many ups and downs, and to be able to carry out witnessing work with a small number of people even if there are many monitoring locations. Furthermore,
The object of the present invention is to provide a monitoring method that can make equipment economically advantageous for carrying out patrol work and witness work at the same time.

Characteristic means of the monitoring method according to the present invention in which remote monitoring is performed by a monitoring means equipped on a trolley that moves on a single-track track set along a patrol route in response to a command from a remote centralized monitoring station is as follows: A terminal and one or more witness monitoring locations are set, and a plurality of said trolleys are provided, and after a specific trolley among said plurality of trolleys is moved to a specific witness monitoring location, a terminal and one or more witness monitoring locations are set. a preparation step of stopping the specific trolley at the specific witness monitoring location; and after moving the following trolley to the specific witness monitoring location, the specific trolley is started in the direction of movement of the following trolley; The system also includes a monitoring step in which the following cart is moved and stopped in a baton-touch operation method in which the following cart is stopped at the specified observation monitoring location, and in the monitoring step, patrol monitoring operations are carried out by a moving cart and patrol monitoring operations are performed by a stopped cart. The purpose of this is to simultaneously carry out on-site monitoring operations, and its functions and effects are as follows.

In other words, for example, if there is one place for witnessing and monitoring, the monitoring means for a specific trolley stopped at that location during the equipment process can be used to conduct continuous witnessing operations from a remote central monitoring station, and the subsequent trolley can be monitored at the desired timing. While moving the trolley toward a specific witness monitoring location, the trolley performs patrol operations from the remote central monitoring station to the witness monitoring location using the monitoring means of the trolley.

When the following truck arrives at the specific witness monitoring location, the truck is stopped, and following the specific truck, the monitoring means of the following truck performs witnessing operations from a remote central monitoring station. On the other hand, while the specific trolley is being moved, patrol operations beyond the specific witness monitoring location are carried out from a remote central monitoring station using the monitoring means of the trolley.

In addition, when there are multiple witness monitoring locations, the following bogie that is the last one with respect to the preceding bogie that has been placed in advance at the witness monitoring location in the preparation process and, for example, that has started from a terminal, will be placed at the witness monitoring location that is closest to this terminal. After arriving at the location, the preceding truck that was stopped at this location will be started, and this operation will be repeated at each location. As a result, the leading trolleys move one after another to the witness monitoring location in front, and the following trolleys take over the witnessing duties at the witnessing monitoring location (each of which is a specific witnessing monitoring location), and the leading trolley then takes over the patrol duties. be.

As a result, both patrol operations and witness operations can be carried out reliably while staying at the observation post with a small number of personnel.In particular, it is possible to reduce the number of personnel involved in monitoring operations in wide areas, and to monitor areas where there is a lot of climbing and descending. It has become possible to sufficiently reduce the workload and improve safety in operations.

Moreover, by adopting the baton touch operation method,
Patrol work and witness work can be carried out at the same time even on a single-track track, making the monitoring equipment extremely advantageous in terms of initial costs and maintenance, compared to, for example, installing tracks for patrol work and witness work in parallel. Combined with the reduction in personnel costs, monitoring can now be carried out extremely economically.

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 central monitoring station 6 is equipped with a control panel 4 for remotely controlling the trolleys 2a to 2d, a monitor television 5 for showing images sent from the television cameras of each of the trolleys 2a to 2d, and the like.

As shown in FIG. 2, the trolley 2 has the following various equipment.

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 (this process is called the preparation process), and the stopped cart 2
A, 2b, 2c television cameras 10, etc. (this is referred to as a monitoring means) are used to witness monitoring locations A, 2c, etc.
Witness operations will be conducted for both B and C from the remote central monitoring station 6.

When patrol work is required, another trolley 2d is moved from the terminal 3 to the nearest monitoring site A via the monorail 1 and operated from the remote central monitoring station 6, and the TV of the moving trolley 2d is displayed. Patrol operations between the terminal 3 and the witness monitoring location A are performed from a remote central monitoring station 6 using a camera 10 or the like. When the trolley 2d from the terminal 3 arrives at the witness monitoring location A, the following trolley 2d is stopped by the stop operating tool 19, and the stopped trolley 2a is moved to the next witness monitoring location B by the start operating tool 18. Move toward the destination. Therefore, the witness operations at witness monitoring location A are continued using the television camera 10, etc. of the following trolley 2d, and the patrol operations between witness monitoring locations A and B are continued using the television camera 10, etc. of the trolley 2a that has started moving. This is done using . In addition, the witness operations at witness monitoring locations B and C will be continued in the same manner as witness monitoring location A, and the patrol operations between witness monitoring locations B and C and between witness monitoring location C and the terminal will be carried out at the witness monitoring locations. A,
Do the same as between B.

Here, the witnessing monitoring location to which the following bogie moves is referred to as a specific witnessing monitoring location, and the bogie that has stopped in advance of this witnessing monitoring location is referred to as a specific bogie. Furthermore, a process in which patrol work and witness work are progressing at the same time is called a monitoring process.

In short, bogie 2a on one monorail 1
By using the baton-touch operation method of 2d to 2d, witnessing operations can be continued at all observation monitoring locations A, B, and C, and patrol operations can be carried out over the entire patrol route.In addition, patrol operations and witnessing operations can be remotely and centrally monitored. This is done while staying at Location 6.

The trolley 2c returned to the terminal 3 from the witness monitoring location C is charged by the charging device 22 at the terminal 3, put on standby, and sent out again.

Next, communication 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 to ensure good communication between the remote central monitoring station 6 and the trolley 2.

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 to improve the performance, and in short, it is sufficient to use the single track track 1.

Make single track 1 into a loop and connect terminal 3 to 1
This has the advantage of making it easier to manage the trolley 2, especially when the trolley 2 is a self-propelled type powered by a storage battery 20. An operation method such as sending out the trolley 2 from the terminal 3 on the opposite side may be adopted. Furthermore, terminals 3 equipped with charging devices 22 and the like may be arranged at a plurality of locations on the loop-shaped single-track track 1 to prevent the trouble of the storage battery 20 of the trolley 2 going up.

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.

Trolley 2 stopped at witness monitoring locations A, B, and C
After the following bogie 2 arrives, it may be started by remote control from the remote central monitoring station 6, or ultrasonic waves etc. may be emitted from the following bogie 2 to cause the stopped bogie 2 and the following bogie to start. The distance to the trolley 2 is measured, and when the distance between both trolleys 2 reaches the set distance, the following trolley 2 issues a transmission command to the stop trolley 2, and the following trolley 2 is controlled by a timer to attend monitoring locations A, B, C may be used to automatically stop the cart, and in short, the baton-touch operation of the cart can be performed in various operation modes.

Communication between the remote central monitoring location 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 communication between the fixed station 24 and the remote central monitoring station 6 or between the fixed stations 24 may be either wireless or wired.

Monitoring targets include, for example, production factories, buildings,
It can be any location that requires wide area patrolling, such as port facilities, ranches, farms, etc.
