Hereinafter, the details of the laser sensor 21a and the monitoring camera 21b constituting the monitoring device 21 will be described.
The laser sensor 21a has a laser light source that emits laser light and a detector that detects the laser light. The laser sensor 21a irradiates the monitoring target region with laser light by the laser light source, and the laser light reflected from the monitoring target region and returned by the detector is detected, or the laser light emitted from the laser light source. It is detected that someone has entered the monitoring target area when the time required for the detection by the detector is shorter than normal.
Here, the laser light source used for the laser sensor 21a may be either a visible laser light source or an invisible laser light source.

  As the monitoring camera 21b, any type of camera can be used as long as it can confirm the presence of a suspicious person from a captured image. For example, a camera having a general imaging function may be used as the monitoring camera 21b. Here, when the night shooting is performed by the monitoring camera 21b, the monitoring device 21 is provided with illumination for illuminating the shooting range of the monitoring camera 21b, or the monitoring camera 21b is a night vision such as a high sensitivity camera or an infrared night vision camera.

As shown in FIG. 3, each monitoring device 21 provided in each container crane 10 has a monitoring target area A <b> 1 wider than the distance between the front legs 11 of the container crane 10 along the quay 101 on the sea side from the front legs 11. It is set as the structure which monitors about A2, ....

Here, the monitoring device 21 may be configured to simultaneously monitor the entire monitoring target area in charge, and a monitoring direction changing device that changes the direction of the laser sensor 21a and the monitoring camera 21b (swings) is provided. Thus, the entire monitoring target area in charge may be monitored by sequentially scanning the monitoring target area in charge one by one.
Furthermore, the monitoring device 21 can remove a part of the monitoring target area in charge from the monitoring target.
Note that “remove from monitoring target” means that monitoring is not performed in the area excluded from the monitoring target, or even if the area excluded from the monitoring target is monitored and an abnormality is detected in this area, the base station 105 indicates that the information management means does not determine that there is an abnormality.

The harbor monitoring system 1 configured as described above monitors the quay 101 by the monitoring device 21 provided in each container crane 10 in parallel with the monitoring in the container terminal T by the terminal monitoring device 106. is there.
Hereinafter, the monitoring operation of the quay 101 by the harbor monitoring system 1 will be described.

First, the monitoring operation of the quay 101 when the cargo handling operation is not performed (standby state) will be described.
Also in the container terminal T to which the harbor monitoring system 1 is applied, in the standby state, each container crane 10 is fixed at a predetermined standby position on the apron 102, similarly to the container crane in the normal container terminal. Is done.
In this port monitoring system 1, the container cranes 10 are arranged at appropriate intervals so that the monitoring target areas A1, A2,... The size of each monitoring target area A1, A2,... Is appropriately set. Thereby, the quay 101 is monitored over the full length with the monitoring apparatus 21 provided in each container crane 10. FIG.

Here, the laser sensor 21a is configured to always perform monitoring while monitoring by the monitoring device 21 is performed.
On the other hand, the photographing by the monitoring camera 21b may be always performed in the same manner as the monitoring by the laser sensor 21a, and is started at an arbitrary timing, for example, when an abnormality such as a suspicious person intrusion is detected by the laser sensor 21a. Also good.

If there is a reaction in the laser sensor 21 a of the monitoring device 21, the information is notified to the base station 105 by the communication means of the container crane 10, and appropriate information is given by the security officer stationed at the base station 105. Action is taken.
Here, since the captured image of the monitoring camera 21b of the monitoring device 21 is also sent to the base station 105, based on the captured image, the security officer stationed at the base station 105 is the site where the abnormality is detected. And verifying whether a suspicious person has actually entered or whether the laser sensor 21a has malfunctioned.
When an intrusion of a suspicious person is actually confirmed, an appropriate response method is determined based on the captured image, and the suspicious person is dealt with.

Next, the monitoring operation of the quay 101 when a cargo handling operation is performed will be described.
First, the container crane 10 used for cargo handling is moved from the standby position to the position where cargo handling is performed while continuing monitoring by the monitoring device 21.
At this time, the interval between the container cranes 10 including the container cranes 10 not used for cargo handling is adjusted so that the monitoring target areas A1, A2,... By the monitoring device 21 of each container crane 10 remain continuous. Alternatively, the size of the monitoring target area of the monitoring device 21 of each container crane 10 is appropriately set.

Then, when carrying out the cargo handling work, the monitoring device 21 is an area in which the cargo handling work is performed, specifically shown in FIG. 3, so as not to misidentify the cargo handling work as an intrusion of a suspicious person. The region between the front legs 11 of the container crane 10 is removed from the monitoring target, and the cargo handling operation is performed in this state.
Here, at the time of cargo handling work, since many workers and monitoring personnel for cargo handling work are arranged around the container crane 10 used for cargo handling, intrusion of suspicious persons from around the container crane 10 used for cargo handling is prevented. It is very difficult.
For this reason, even if a part of the monitoring target area is excluded from the monitoring target as described above, there is no fear of overlooking the intruder.

In this harbor monitoring system 1, since the monitoring device 21 is provided in the container crane 10 itself that handles the container C, the monitoring can be performed without interfering with the cargo handling operation and the movement of the container crane 10. .
Thereby, monitoring of the quay 101 which was impossible conventionally is easily performed, and management of the container C handled by the container terminal T can be carried out thoroughly. For this reason, from the container terminal T, the container C can be shipped to a country or a port where conditions for receiving the container C are severe.

  In addition, if necessary, the monitoring status of the container terminal T may be attached to the container C as documents, video information, electronic data, etc. to prove that the management of the container C is thorough. it can.

Here, the power supplied to the container crane 10 is used as the power source of the monitoring device 21, and the communication means of the container crane 10 is used for communication with the base station 105. There is no need to newly provide power supply equipment or communication means for the device 21.
Furthermore, since the container crane 10 itself is used as a structure for installing the monitoring device 21, it is not necessary to newly provide a column or the like for the monitoring device 21.
Thus, the port monitoring system 1 has a lower installation cost than the case where the monitoring device 21 is provided independently of the container crane 10.

  Moreover, in this harbor monitoring system 1, since the monitoring device 21 can exclude the area where the cargo handling work is performed on the quay 101 from the monitoring target, the cargo handling work is not mistaken for the intrusion of the suspicious person, and the quay 101 Cargo handling work can be performed while monitoring.
