Anti collision devices

Types of Anti Collision Devices

There are many types of anti-collision devices that help to prevent collisions between people, objects, and machines. Some of the most popular types include proximity sensors, pressure pads, laser scanners, emergency stop buttons, and light curtains.

• Proximity Sensors

  Proximity sensors are devices that detect the presence of nearby objects or people without any physical contact. They can be used for collision prevention with the help of different sensing technologies. Proximity sensors can be installed on vehicles, machines, or mobile work centers to sense if any objects or individuals are nearby and give a warning or perform an action to avoid a collision. They are widely used in various applications for collision prevention. For instance, in forklifts equipped with proximity sensors, the sensor can detect when an individual is nearby, and the system can issue an audible alarm to notify the operator of a potential collision risk.

• Pressure Pads

  Another common device used in anti-collision systems is pressure pads. Pressure pads are devices used to detect exerting pressure or force. They are usually placed on the ground as flooring or turf. In an anti-collision system, pressure pads can be used as sensing devices to detect the presence of individuals or objects within a certain area. When pressure is exerted on the pressure pad, it sends a signal to the anti-collision system that triggers a predefined response to prevent a collision. For example, in an industrial setting, a pressure pad can be placed in a certain zone where forklifts operate. If a pedestrian steps into that zone and exerts pressure on the pressure pad, the anti-collision system may trigger an alarm to alert the pedestrian and the forklift operator to prevent a potential collision.

• Laser Scanner

  Laser scanners are devices that use laser beams to scan and detect objects or obstacles in their range. They work by emitting laser beams that rotate or sweep across a certain area, measuring the distances to the objects within that area, and creating a spatial representation of the surroundings. Laser scanners can be used in anti-collision systems to detect the presence of individuals, objects, or obstacles within a certain vicinity and provide information for collision avoidance. Laser scanners can be mounted on vehicles or machines as part of the anti-collision system. They can monitor the area around the vehicle or machine in real-time by scanning for any potential obstacles or collisions. The data collected by the laser scanner is processed by the anti-collision system, and actions such as warnings, alerts, or automatic braking can be initiated to prevent collisions.

• Emergency Stop Buttons

  Emergency stop buttons are special buttons used to immediately stop the operation of machines, equipment, or systems in emergency situations. They are usually red buttons that are easily recognizable and can be manually pressed to stop the operation of the equipment. In an anti-collision system, emergency stop buttons can be an important device to prevent potential collision hazards. Once a sudden danger arises, the operator can press the emergency stop button to immediately stop the operation of the equipment, thereby reducing or avoiding the occurrence of a collision. For instance, in an automated production line, an emergency stop button can be set on a laser cutting machine. If the operator finds that a nearby worker is at risk of being injured by equipment, they can immediately press the emergency stop button to stop the machine from colliding with the worker.

• Light Curtains

  A light curtain is an electrosensory device that comprises a set of vertical laser beams and photodetector columns. They are often used in access points or dangerous areas to monitor the presence of people or objects. In an anti-collision system, light curtains can be used to detect unauthorized entry or intrusion into a safety zone, thereby preventing potential collisions. Light curtains can be integrated into the anti-collision control system. Once the light curtains detect that an individual has intruded into a danger area, they can send a signal to the anti-collision system for action. For example, a light curtain can be set on the laser cutting area of an equipment. If the light curtain detects a pedestrian entering the area, it can send a signal to the anti-collision system. The system may take actions such as an alarm or an automatic stop to prevent a collision.

Specification and Maintenance

• Performance parameters:

  The performance indicators of the anti-collision device mainly include reaction time, working frequency, sensitivity, and so on. Reaction time refers to the time from the perception of the object to the commencement of the response, which is crucial to ensure timely reactions. The working frequency indicates the operating frequency range of the device, which determines its applicable environment and scope of use. Sensitivity reflects the ability of the device to perceive surrounding objects and changes, which affects the effectiveness and accuracy of collision avoidance.

• Operating Environment:

  The working environment of the anti-collision device is critical to its performance and lifespan. It is necessary to ensure that the temperature, humidity, dust, and other factors of the device's use environment conform to the specifications and requirements, thus reducing the risk of equipment failure and malfunction. For example, in high-temperature or humid areas, anti-collision devices may require additional cooling or moisture-proof treatment to adapt to harsh environments.

• Power supply:

  Anti-collision devices typically utilize electrical energy, which may require batteries or external power sources. Furthermore, it is necessary to monitor and maintain the power supply system to ensure the operational stability and reliability of the device.

• Installation and Adjustment:

  According to the device's manual, properly install and adjust the anti-collision device to ensure its fixed state and the proper place. Regularly check the installation condition and adjust it as needed to ensure stability and effectiveness.
