Electric infrared wireless remote voice reporting circuit

The 555 circuit, which contains two voltage comparators, a basic RS flip-flop, and a discharge switch T, the comparator's reference voltage is provided by a voltage divider consisting of three 5K resistors. They respectively make the non-inverting input of the high-level comparator A1 and the inverting of the low-level comparator A2, and the reference levels of the input terminals are 2/3VCC and 1/3VCC. The outputs of the A2 and A2 control the RS flip-flop state and Discharge tube switch status. When the input signal is from the 6 pin, that is, the high level triggers the input and exceeds the reference level 2/3VCC, the flip-flop resets, the output of the 555 pin 3 outputs a low level, and the discharge switch tube is turned on; when the input signal is from 2 The input of the pin is lower than 1/3VCC, the trigger is reset, the 3 pin of 555 outputs high level, and the discharge switch tube is cut off. RD is the reset terminal (4 pins). When RD=0, 555 outputs a low level. Usually the RD end is open or connected to VCC.

High Speed Slip Ring

A high-speed slip ring is an electromechanical device that allows electrical current to pass between a stationary and a rotating assembly. It is typically used in applications where the speed requirement exceeds that which is achievable with a standard slip ring. High-speed slip rings are available in a variety of sizes and configurations to meet the needs of most applications. They are commonly used in military, aerospace, and medical applications where speed and reliability are critical.

The speed is required to be at least tens of thousands of revolutions per minute, the structure of the Conductive Slip Ring directly determines the contact of high speed, as well as the size of impedance. High-speed slip ring materials have high wear resistance, high life characteristics, and multi-contact contact can ensure signal transmission and power reliability, with the development of science and technology, high-speed slip rings will be more and more widely used.

If you need to transfer large amounts of data or power between two stationary objects, a high-speed conductive slip ring is what you need. Traditional slip rings only offer a few thousand revolutions per minute (RPM), which is more than enough for most applications, but can be limiting in some circumstances. Some applications, like those found in the medical or military field, require speeds of tens of thousands of RPM in order to function properly. That's where our high-speed conductive slip ring comes in. With speeds up to a certain range, it can handle even the most demanding applications.
