It is the high cost performance of laser pointer .
The signal amplification, the selected frequency and pulse demodulation, since the output low, after VT1 reverse, acting on the D1 side of BA5204, through the circuit, the decoded output by the BA5204 3 to 10 feet the control signal. When press the transmitter K1 ~ K6 any to BA5204 corresponding HP-ended output high, release the launch button, the output low; CP1, CP2 end is self-locking reverse level output when you press the K7 , K8, a key, flip of the the BA5204 corresponding CP-ended output level, each time you press, the output level flip once. C1, C2 end user code input. There are four kinds of encoding requirements BA5104 of C1, C2 side settings. Capacitor C1, resistor R2 and BA5204 13 feet of the internal circuit, oscillation circuit, a frequency of 38kHz. The customer should choose laser pointer according to the actual needs of themselves.Avoid causing damage to roads and transport facilities around a major traffic accident. The use of laser photoelectric switches can detect ultra-high vehicle overrun. Figure 12 Schematic diagram of the train vehicle detection devices. Magnetic transducers installed to drive direction about 100m from the detection system, when the wheels of the locomotive of a magnetic transducer, the device boot signal sent to the detection system, the system started working. When the vehicle through the detection system, if an object blocked the laser beam, the receiver will send out alarm signals, if you configure a set of software according to statistics compiled by the axle of the vehicle structure and vehicle can be informed Which car, ultra-high overrun. The higher the performance of laser pointer is, the higher the cost performance of the laser pointer is.
However, at this time need two magnetic sensors installed at regular intervals. Auxiliary information in order to provide the necessary wheel spacing, and speed. Textile system. In the textile industry, there are a lot of spinning machinery in the work of more than ten meters wide, spinning machinery, a number of spindles in operation, if a yarn break, you need to be shut down by the operator to connect the decapitation . Laser photoelectric switch off yarn online testing operations. In the bottom of the cotton yarn path, the vertical direction of movement in cotton yarn, install the transmission of laser transmitters and receivers, so that block the path of the laser beam receiver output alarm signal, so stop spinning machinery, cotton yarn break whereabouts at this time can be completed in the wiring. And at the same time, the lower the price of laser pointer is, the higher the cost performance of the laser pointer is. Recently, we introduced a smaller, portable laser marking machine, the machine is only the computer chassis generally.
