This invention provides a laser wavelength locking method based on waveform feature analysis, comprising the following steps: acquiring waveform sampling data of a laser detection signal; identifying signal feature points of the laser detection signal and calculating the average index and index change value of the signal feature points; adjusting the voltage range of the laser driving signal in real time until the voltage range of the laser driving signal matches the sampling point index range of the laser detection signal waveform; performing peak detection on the rising edge or falling edge waveform data to obtain multiple peak sampling points; selecting a target peak sampling point from the multiple peak sampling points based on the energy level transition type of the cesium atom D2 line, and using the voltage value corresponding to the target peak sampling point as the upper and lower limit thresholds of the voltage range of the laser driving signal to achieve laser wavelength locking. This invention solves the problems of slow locking response speed and insufficient dynamic adjustment capability in existing technologies.

The application discloses a delay-locked loop circuit, a chip and electronic equipment, the delay-locked loop circuit comprises a first delay chain, a second delay chain, an SR latch and a digital control unit, the digital control unit is in a coarse adjustment stage, when a compensation signal is a non-target value, the current first delay offset code is increased, in a fine adjustment stage, when the compensation signal is the non-target value, the current second delay offset code is increased, until the received compensation signal is the target value, entering a locked state, the SR latch inputs a first delay signal and a second delay signal, and outputs a compensation signal.Because the delay-locked loop circuit is based on the mixed mode of digital design and analog design, the circuit structure is simple, the adjustment is carried out in stages through the digital control unit, high-precision clock phase adjustment can be realized, the control is simple, the locking time is short, the calibration process is simple, in addition, the SR latch is used in the delay-locked loop circuit, compared with using a phase detector, the locking precision can be improved.

This utility model discloses a cable reeling device for power construction, including a cable reeling assembly, a position adjustment mechanism, a position fixing mechanism, and a fixing auxiliary mechanism. The position adjustment mechanism includes a carriage and a lifting plate. The position fixing mechanism includes a bottom fixing tube and a locking rod. The fixing auxiliary mechanism includes an outer fixing plate and a drive ring. The position adjustment mechanism achieves precise height adjustment of the cable reeling device through the ingenious cooperation of the carriage, lifting plate, adjusting rod, and adjusting hole. The design of the guide rod and guide sleeve ensures stable and vertical lifting, avoids swaying, and significantly improves adjustment accuracy. The position fixing mechanism adopts a combination structure of bottom fixing tube, locking tube, and locking rod, creating a quick locking system. After the locking rod passes through the adjusting sleeve and adjusting hole, simply rotating the locking tube allows the corner frame to extend into the receiving block to form a mechanical lock.
