Description

Technical Field

[0001] The invention belongs to the technical field of container twist lock detection, and in particular relates to an intelligent detection alarm system and method for removing a lock pad before stacking a container. Background Art

[0002] When loading shipping containers, multiple containers need to be fixed by twist locks when stacking to prevent the containers from falling and causing losses due to the bumps of shipping. Container trailers at freight ports have fixed driving routes. When the trailers are loaded and transferred to the yard, in order to improve the transfer efficiency, the driver can only stop the trailer after it leaves a specific area. In addition, there are generally multiple side-by-side bridge cranes next to the container ship berths for lifting containers from the freighter. Therefore, when the cargo ship arrives at the port, due to the urgent time for unloading, multiple trailers are parked on the one-way road under the bridge crane in a specific area of ​​the port, waiting in line for the transfer of containers.

[0003] When unloading, the workers on the ship open the twist locks so that the upper and lower containers can be separated smoothly. At this time, the twist locks are still hanging on the upper container. Then, the port crane lifts the container from the ship to the trailer waiting for loading on land, and the workers remove and recycle the hanging twist locks one by one. However, due to long-term and high-intensity work, workers often forget to remove the twist locks, and there are also cases where trailer drivers forget to go to the unlocking area to remove the locks.

[0004] Chinese patent (CN202322192170.1) discloses an anti-lifting detection device for container trucks, which belongs to the field of anti-lifting detection technology, including a vehicle body and a container located on the vehicle body. The front and rear ends of the loading platform of the vehicle body are inlaid with storage boxes, and the internal lifting of the storage box is connected to a detection host. A laser beam sensor is fixedly installed on one side of the detection host. When in use, when the container is lifted, the laser beam sensors receive the beamed lasers from each other and judge that the container is separated from the vehicle body. When the laser beam sensor does not detect the beamed lasers, it means that the container is not separated from the vehicle body, and the upper laser distance sensor and the lower laser ranging sensor are used to further judge whether the container is separated from the vehicle body. When the container is lifted without separation, the alarm sounds an alarm to prevent the risk of lifting the vehicle body.

[0005] At present, there is no system on the market specifically designed to determine whether the twistlocks have been successfully removed when unloading containers at ports. As a result, trailers still carry twistlocks when transferring containers from ports, posing a risk of multiple containers being lifted together when shipped from the yard. Summary of the invention

[0006] The purpose of the present invention is to solve the above-mentioned problems and to propose an intelligent detection and alarm system and method for removing the lock pad before stacking a container.

[0007] On the one hand, in order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: an intelligent detection and alarm system for removing the lock pad before stacking a container, comprising:

[0020] As a further description of the above technical solution:

[0021] The twist lock identification sensor is a laser beam or laser reflection sensor.

[0022] As a further description of the above technical solution:

[0023] The communication connection mode is any one of RS232 communication, RS485 communication and CAN bus communication.

[0024] On the other hand, in order to achieve the above-mentioned purpose, the present invention adopts the following method: a method for intelligent detection and alarm of removal of lock pads before stacking containers, which comprises the following steps:

[0025] 1) The alarm device obtains the positioning information of the locator, the trailer is in the designated area, and the twist lock recognition sensor is not activated;

[0026] 2) After the container falls into the trailer and the trailer drives out of the designated area, the positioning information of the locator is fed back to the alarm device, and the alarm device controls the twist lock recognition sensor to start;

[0027] 3) If a twist lock is not removed, the twist lock identification sensor is triggered and sends a signal, and the signal is sent to the controller connected to it, and the controller controls the alarm device to alarm, and the controller controls the display screen to display the alarm information of the corresponding twist lock identification sensor number, so that the driver removes the twist lock in time;

[0028] 4) The controller will record and save the corresponding alarm information for subsequent tracking and verification.

[0029] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0030] In the present invention, a locator is used to determine the position of the trailer in real time. When the trailer leaves a specific designated area, a twist lock recognition sensor is used to detect whether the twist lock remains on the container. An alarm message is displayed on a display screen in the trailer cab, and an alarm device sends an alarm signal to remind the driver to remove the lock in time, thereby avoiding the situation where the trailer is still carrying the twist lock when transferring containers from the port, and eliminating the risk of multiple containers being lifted together when shipping from the yard.
