لیدار یکی از روش های نوین سنجش از راه دور است که با تاباندن لیزر به هدف، فاصله را تشخیص و اندازه گیری می کند. رادار اسکن لیزری 360 درجه از تراشه STM32 استفاده می کند. چرخش
و مدارهای داخلی از منبع تغذیه بی سیم ، و انتقال داده از پرتو مادون قرمز استفاده می کنند تا از مشکل سایش اولیه حلقه لغزش جلوگیری شود. این رادار شباهت زیادی به EA1 X2 دارد. رابط رادار همچنین داده ها را مستقیماً از طریق پورت سریال خروجی می دهد.
حداکثر فرکانس اندازه گیری این رادار 4000 نقطه در ثانیه و نرخ باود 115200می باشد به علاوه رادار از تنظیم سرعت PWM برای تنظیم فرکانس اسکن، تعریف رابط پشتیبانی می کند. دنباله از VCC، TXD، GND، RXD نزدیک به موتور شروع می شود.
Description:
The original brand new stock brand 360-degree laser scanning radar, triangular laser ranging rotation mapping modeling radar, the original arrived and was produced at the end of 21, the goods are very beautiful, the original box is 64 PCS per box. The internal workmanship of the radar is very good. The scanning movement head is CNC machined and blackened from a single piece of aluminum. The main control uses an STM32 chip. The radar rotation and internal circuits use wireless power supply + infrared beam data transmission to avoid the original early Slip ring wear problem. This radar is very similar to the EA1 X2 that the shop owner has sold before, and the incoming goods are also from a batch of EA1. It is probably related to the EA1 product. Some parameters are probably the same. The radar interface also outputs data directly through the serial port. . New product specials, research product prices and sales, you can probably find information online and do your own research. Do not support arbitrary 7 days. The radar weighs approximately 105 grams. Priced for a single radar.
The shop owner learned from the upstream that the maximum measurement frequency of this radar is 4000 points/second, the interface is 5V uart serial port, the baud rate is 115200, the output content angle, distance, etc., the interface power supply is 5V, the radar supports PWM speed adjustment to adjust the scanning frequency, interface definition The sequence starts from VCC, TXD, GND, RXD close to the motor. The above information is for reference only.
Now a customer has provided test data, which also verifies the store owner’s previous guess. This radar is fully compatible with the EA1 and X2 on sale in the store. If you need it, you can contact the store owner. The baud rate of this radar is 115200.
