Problems solved by technology

[0003] The existing technology manually controls the running track and running time of the spreader, and it is easy to cause the spreader to fail when the operator is inattentive, fatigued or inexperienced, and dust, water mist or blind spots are raised around the vehicle. Collision accidents occur, and the operator's operating status cannot be analyzed at the same time. According to the operator's operation factor, the operator is reasonably arranged to take turns to rest, enhance the operator's safety awareness, and improve operating efficiency.

Embodiment 1

[0047] Such as figure 2 As shown; the position acquisition module is used to obtain the current position of the spreader and the position of the target container to determine the running track of the spreader; the position includes the position in the horizontal direction and the vertical direction, and the running track is a straight line; the position acquisition module is used to obtain the position of the spreader The running trajectory is transmitted to the controller;

[0048] The environment collection module is used to collect the real-time environment information outside the spreader in real time, and transmit the real-time environment information to the speed acquisition module; the speed acquisition module is used to determine the corresponding running speed of the spreader according to the real-time environment information, and the running speed includes horizontal running speed and Vertical running speed; real-time environmental information includes temperature i...

Embodiment 2

[0057] Such as image 3 As shown, the radar module is composed of laser radar and ultrasonic radar, which is used to monitor the distance information of obstacles around the spreader in real time and transmit the distance information to the data analysis module. Obstacles include people, vehicles and other containers except the target container, etc. ; The data analysis module is used to receive distance information and analyze the distance information to determine whether there are obstacles on the running track; the specific analysis steps are:

[0058] S1: Obtain the real-time distance information of the obstacle, and mark the real-time distance information as L1; establish a graph of the real-time distance information changing with time, and mark it as the obstacle distance graph; according to the change of the real-time distance, the obstacle distance curve The graph is divided into ascending phase, resting phase and descending phase;

[0059] S2: When the real-time dist...

Embodiment 3

[0065] Such as Figure 4 As shown; in a working cycle of the quay crane, the monitoring module communicates with the controller to monitor the braking signal. The specific steps are:

[0066] V1: In a working cycle of the quay crane, when the monitoring module detects that the controller receives the braking signal, record the braking moment at this time;

[0067] V2: Automatically count down when the brake signal is detected, the countdown time is T2 time, T2 is the preset value; continue to monitor the brake signal during the countdown period, if a new brake signal is generated, the countdown will automatically return to the original value, count down again according to T2; otherwise, count down to zero and stop counting down;

[0068] V3: Count the number of braking signals in the countdown phase and mark them as braking frequency C1;

[0069] Sort all the braking moments according to the order of time, and calculate the time difference between the two adjacent braking mo...

Abstract

The invention discloses an adaptive emergency braking control system for a quay bridge spreader, which relates to the technical field of port machinery; The personnel scheduling module; the speed acquisition module is used to determine the corresponding running speed of the spreader according to the real-time environmental information, effectively reducing the occurrence of spreader collision accidents, and making the spreader run more smoothly and safely; at the same time, when the environment is bad, the system will give early warning in time and automatically start the emergency response. Brake to improve the safety awareness of the operator; the data analysis module is used to analyze the distance information and judge whether there are obstacles on the running track for collision reminder and emergency braking; at the same time, the invention monitors the operator's operation through the monitoring module The state is analyzed, and the operator is reasonably arranged to take turns to rest according to the operator's operation coefficient, so as to reduce the collision accident of the spreader and improve the operation efficiency at the same time.

Description

technical field [0001] The invention relates to the technical field of port machinery, in particular to an adaptive emergency braking control system for a quay crane spreader. Background technique [0002] With the globalization of economic development, the demand for international transportation has greatly increased, and international container transportation dominated by maritime transportation has developed rapidly; shoreside container cranes (referred to as shore cranes) are the main equipment for loading and unloading containers at the front of the port. In the working cycle of the bridge, the operation time of the quay crane for box alignment, box removal and box release is relatively fixed, while the time for the lifting of the spreader and the running of the trolley will vary due to the different running trajectories of the spreader. During the operation of the existing quay crane, the running track of the spreader is controlled by the operator operating the lifting...
