Ultrasonic sensors require two parts: a transmitter and a receiver
With the rapid growth of the demand for logistics intelligence, forklifts, as the core equipment for processing, are entering the intelligent process faster and faster. As a popular type, forklift AGV plays an important role in industrial manufacturing, logistics, warehousing and other industries. AGV has the characteristics of high efficiency, flexibility, independence and safety. AGVs have gradually replaced manual assembly, handling, stacking, and unloading, and have made important contributions to smart factories and smart workshops.
Although AGV forklifts have entered a period of rapid development, they still face major problems in practical use. The primary consideration for major smart forklift manufacturers is how to achieve accurate positioning, automatic path planning, target pallet search, detection, hole alignment, handling and loading and unloading. Due to the complex placement environment of goods inside the warehouse and the inaccurate position of pallets on manual/trucks, unmanned forklifts cannot accurately identify pallets through traditional mechanical limitations or monocular camera identification methods. Generally speaking, the unmanned forklift has a large deviation angle from the pallet position, which leads to the failure of entering the forklift. If there is a certain distance or angular deviation between the pallet position and the set position, the forklift cannot cross and needs to be handled manually, which greatly reduces the overall transportation efficiency.
The ultrasonic sensor BA2904YFV-CE2 requires two parts: a transmitter and a receiver. In the most standard configuration, they are as close and placed as possible. When the receiver is close to the transmitter, sound is transmitted from the transmitter to the detected object and back to the receiver in a straighter fashion, resulting in less measurement error. There is also an ultrasonic receiver in which the transmitter and receiver functions are integrated in one unit to minimize physical errors. The sound waves leaving the transmitter are more similar in shape to those leaving a flashlight, so the angle of transmission and beam must be considered. As the sound waves get farther and farther from the transmitter, the detection area will increase both horizontally and vertically. The changing area is why ultrasonic sensors give coverage based on the width or angle of the beam, rather than the standard detection area. When the manufacturer compares the angle of the beam, it is recommended to verify whether the angle of the beam is the full angle of the beam or a straight angle to the sensor.
A secondary effect of beam angle is the range of the device. Typically, narrow beams result in greater detection range because the energy of the ultrasound pulse is more concentrated and can travel farther, dissipating to the point of being unusable. Conversely, a wider beam spreads the energy over a wider arc, reducing the expected detection range. The choice of the ideal beam width depends largely on the degree of application. Wider beams are better for larger coverage and general detection, while narrower beams limit the detection area to avoid false reports. Ultrasonic Sensor - MB1210 is a lower cost ultrasonic sensor that can measure long distances (up to 7.65 meters). Not only does it have real-time calibration, but it can continuously and variably increase data for more accurate data. Wide power supply voltage: 3.3V~5V, low power consumption is also suitable for battery-powered systems. In the MB122 series products with the same performance, there is also a distance ultrasonic sensor, which can measure the MB122 series products.
