Frequent false alarms from ordinary anemometers? What black tech is hidden in Dayu's ultrasonic device?
Regarding inquiries about coal mine tunnel anemometers, the following is a detailed response to customer questions and a product introduction:
1. Device output and working principle
Device output: The coal mine tunnel anemometer does not directly output time, but calculates wind speed based on the time difference between transmission and reception of signals by the ultrasonic transducer.
Working principle: The device consists of 1 circuit board, 1 set of MCU software, and 2 ultrasonic transducers. Normally, transducer No. 1 transmits the ultrasonic signal, and transducer No. 2 receives it. If mutual transmission between the two transducers is required to measure the time difference, the circuit board and software must be adjusted accordingly.
2. Underground explosion-proof and electromagnetic interference
Underground explosion-proof: Due to the special underground environment containing explosive gases, the device must have explosion-proof functionality. The existing ultrasonic development board does not account for explosion-proof or electromagnetic interference issues, so it must be redesigned to meet underground operational requirements.
Electromagnetic interference: During the redesign process, electromagnetic interference will be fully considered to ensure stable operation of the device in the complex underground environment.
3. Communication circuit and transmission distance
Communication circuit: The current development board does not integrate communication circuits such as RS-485 or CAN. To meet long-distance transmission requirements, users must design their own communication circuits.
Transmission distance: The device can operate stably in underground environments spanning several kilometers, but the specific transmission distance depends on the actual underground conditions and the communication circuit design.
4. Probe protocol and secondary development
Probe protocol: The ultrasonic probe is a passive analog component, similar to a capacitor, so there is no protocol issue. Users can design circuits and software as needed to connect with the probe.
Secondary development: We offer customized circuit board and MCU software services, and can perform secondary development based on user requirements to meet the needs of specific application scenarios.
5. Product advantages and applications
Product advantages: The coal mine tunnel anemometer features high accuracy, high stability, and strong explosion-proof and anti-interference capabilities, effectively improving production efficiency in the coal mining industry and ensuring worker safety.
Applications: This product is widely used in coal mine tunnel wind speed measurement, environmental monitoring, and safety warning applications, bringing unprecedented convenience and innovation to the coal mining industry.
The coal mine tunnel anemometer is a wind speed measurement device specifically designed for the coal mining industry, offering numerous advantages and broad application prospects. We can provide customized services based on customer requirements to meet the needs of different application scenarios.
