The laying of the expressway has facilitated our daily travel to a great extent. The relevant departments have installed active and safe traffic guidance lights on both sides of the expressway, allowing the driver to clearly see the direction and contour of the road on the road sections with relatively low visibility. The driver's ability to recognize the road surface. In order to solve the problem of synchronous lamp flickering, the GNSS time module is used to synchronize the clocks of all the induction lamp control circuits on the road section to realize that the induction lamp flickers at the same clock beat, thus solving the problem of synchronization lamp flashing. This SKYLAB is for everyone to briefly introduce the application of the GNSS timing module in highway induction lights.
GNSS timing module
The GNSS time service module supports GPS/BDS/GLONASS to provide not only location information based on latitude and longitude, but also accurate time service. The GPS clock is a receiving device that receives a low-power radio signal transmitted by a GPS satellite and calculates the GPS time by calculation. In order to obtain accurate GPS time, the GPS clock must first receive signals from at least four GPS satellites and calculate its own three-dimensional position. After the specific position has been obtained, the GPS clock can receive only one GPS satellite signal to ensure the accuracy of the clock's travel time. This means that even if the GPS satellite signal conditions are unfavorable or the sky visibility is poor, it can be accurately timed. . In addition, the module also provides NMEA0183 standard message output time and latitude and longitude information through the serial port.
Application of GNSS Time Service Module in Freeway Synchronous Induction Lamp
The synchronous induction lamp control circuit is mainly composed of a single-chip microcomputer, a GNSS timing module, a GNSS timing module power supply control circuit, a illuminance sensor and an LED driving circuit. The single-chip microcomputer receives the GNSS timing module clock data through the serial port, and outputs 1PPS when the GNSS timing module synchronizes to the satellite signal. The second pulse, the second pulse signal is input to the external interrupt of the one-chip computer, is used for synchronizing the internal clock of the one-chip computer, so can achieve the time synchronization.
SKYLAB GNSS Time Service Module
GNSS timing module is SKYLAB launched a series of high-precision timing module for base station, power, communications and other applications, this series supports GPS/BDS/GLONASS, enhanced sensitivity and parallel double-star receiver to expand the coverage, improve the integrity to deal with Bad environment.
This series of modules can use auxiliary functions such as EASY and EPO to provide excellent positioning performance under weak signals and greatly shorten the first positioning time.

The best price/performance module in the existing market
The GNSS timing module has no other wired connection, no line failure leads to synchronization failure, strong system stability, high accuracy, all-weather, global coverage, and free use. In addition to navigation, positioning, and other functions, the precise atomic clock on the satellite Accurate timing can be achieved. At present, it is widely used in applications requiring high precision in time control, such as power, post and telecommunications, communications, transportation, shipping, and weather. More selection applications based on the GNSS timing module can directly access SKYLAB official website or Ali store.
The terminal is used to facilitate the connection of wires. It is actually a piece of metal enclosed in insulating plastic. There are holes at both ends to insert wires. There are screws for fastening or loosening, such as two wires, sometimes Need to connect, sometimes need to be disconnected, then you can use the terminal to connect them, and can be disconnected at any time, without having to solder or twist them together, very convenient and fast.
