Direct current motor forward and backward rotation detection method
There are several ways to detect the positive and negative rotation of a direct current motor: 1. ** Using sensors to detect **: install one or more Hall sensors or proximity switches on the outside of the direct current motor. When the direct current motor turns, the sensors will transmit the rotation information to the processor to determine the direction of the direct current motor. 2. ** Detection by voltage comparison **: By comparing the voltage at both ends of the motor, it can determine the positive and negative rotation of the motor. 3. ** Based on special circuit detection **: - A positive and negative reversal detection circuit is adopted. The circuit includes a first circuit and a second circuit, and the two circuits are respectively provided with a one-way conducting device. The two ends of the first circuit are connected with the two ends of the direct current motor. When the direct current motor is rotating forward, the one-way conducting device of the first circuit is conducted, and when the direct current motor is rotating backward and at rest, the one-way conducting device of the first circuit is cut off. The two ends of the second circuit are also connected with the two ends of the motor. When the direct current motor is rotating backward, the one-way conducting device of the second circuit is conducted, and when the direct current motor is rotating forward and at rest, the one-way conducting device of the second circuit is cut off. - Using a circuit structure similar to the H-bridge, the current circuit was changed by controlling the on-off of different switches in the circuit (such as the H-bridge circuit consisting of a MOS tube or a triode instead of a mechanical switch), so as to realize the forward and backward rotation of the motor. The forward and backward rotation state of the motor could be judged according to the control logic of the circuit and the current flow direction. 4. ** Mechanical structure detection device **: The device is provided with an upper support seat and a lower support seat, the lower support seat is provided with a rotating linked rotating shaft, the upper end of the linked rotating shaft is provided with a loading mechanism, the lower end of the linked rotating shaft is provided with a motor shaft fixing sleeve for fixing an output shaft of a motor to be tested, a stop mechanism is arranged near the linked rotating shaft and corresponds to the loading mechanism, a sensing mechanism is arranged at one end of the upper support seat and corresponds to the loading mechanism, a display seat is extended upwards from the upper support seat, and an indicator light group which is connected with the sensing mechanism is arranged on the display seat. The rotation direction of the load bearing mechanism was used to determine the forward and backward rotation of the motor, and the sensing mechanism and the indicator light group displayed the judgment result. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Aptamer and Nucleic Acid Amplification Reaction
Aptamers were DNA, DNA sequences, XNAs (Nucleic Acid Anomalies), or peptids. Oligo fragments were usually obtained from a library of DNA molecules through systematic evolution of ligands by exponential enhancement (STAR). It could bind with a variety of target substances with high specific and high selection, and was widely used in the field of biosensors. Nucleic acid amplification reaction was the core of gene detection technology. It was a means to amplify the amplification of low-abundance DNA to a detectable level. The reaction time accounted for about two-thirds of the entire gene detection time. Common constant-temperature amplification reactions, such as rolling circle amplification, used the circular DNA as a template to amplify the target DNA molecules. However, the amplification speed was limited by the size, sequence, and topography of the DNA template, and was lower than the speed in the body. In the field of DNA detection, there were also some special techniques based on aptamers or amplification reactions. For example, the Isothermal Amplification by Isothermal Amplification (ERA) technique could specifically amplify trace amounts of target DNA fragments at low temperatures (25 - 42 ° C). The optimal temperature was 35 - 40 ° C, and the amplification reaction could be completed in 15 minutes. There was also a method that did not require pre-amplification and prismatic detection. It used a specially designed TE probe to detect viral DNA. These technologies had low requirements for hardware equipment and could be applied in a variety of fields, such as in vitro-diagnosis, veterinarians, food safety, biosafety, agriculture, and so on. It was not clear whether there was a direct interaction between aptamers and the amplification reaction, but they were both important concepts in the field of detection. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
