How to solve the problem of solar street light controller
LED street lights, solar street lights, etc. will inevitably encounter problems in the process of application, but when the street lights are not on, we must find out the reason, so as to avoid unnecessary accidents. Changhui solar street light manufacturer summarized some experience in recent years, and tells you about the common problems and treatment methods of solar controllers in daily life. I hope it will be helpful to you. If the indicator light of the solar street light controller is on and not on, it may be that the quality of the controller is not good, so in order to ensure the normal operation of the solar street light, you must choose good quality components, which not only prolongs the service life of the components, but also It can also extend the service life of street lights. If there is a problem with the solar street light controller, the solution is: first check whether the photocell is connected correctly and whether there is a bad connection at the wiring place, and then check whether the battery is connected reliably, or whether the battery voltage is normal, if If the voltage is too high, the battery power supply will fail. If the battery is over-discharged, it will automatically recover after being fully charged. Any part of the problem will cause the solar street light to not work normally. Therefore, in our daily life, we must increase the supervision of the street light.
Q: What should I pay attention to when building the provided reference version design data? Which parameters have a greater impact on the consistency of the module?
A: 1) The thickness of the board (or the laminated structure of the board) and the dielectric constant of the board. 2) The consistency of sheet thickness and dielectric constant is most closely related to the consistency of the module.
CHZ in the Spanish Lighting Exhibition, MATELEC
On November 13-November 20, 2018, the Spanish electronic power installation and lighting exhibition MATELEC was grandly opened, and CHZ Spain branch participated in the lighting event. MATELEX is one of the most important exhibitions in Spain and has a high reputation in international exhibitions.
Q: What should I pay attention to when installing or using the radar module?
A: 1) The sensing distance is tested under ideal conditions. The actual sensing distance is related to the hanging height, the openness of the test site, the height and shape of the tester, and the pace of the tester. The sensing distance of the final product is recommended to be subject to the actual measurement; 2) When the radar sensors are densely distributed, try to ensure that the antennas of the radar are parallel to each other to avoid direct illumination between the antenna surfaces. →For scenarios where the radar antennas may illuminate each other, it is recommended that the installation distance exceeds 1m; →For scenes that require dense distribution such as aging test, ensure that there is a distance of more than 20cm between the lamps. 3) Microwave induction radar has a certain wall penetration capability, which can penetrate thin wooden walls and glass walls, but generally does not easily penetrate solid brick walls.
Q: For end products that need to be connected to the Internet, what should be paid attention to nowadays when radar sensors and wifi/BT/NB coexist?
A: 1) Stagger as much as possible in space, and extend the distance between the antenna of the IoT module and the antenna of the radar; 2) Stagger the time as much as possible, and shield the radar sensor signal when the IoT module communicates; 3) Stagger the frequency as much as possible, and avoid the corresponding communication frequency by adjusting the frequency of the radar sensor.
Q: Which external components will affect the radar module and what should be paid attention to?
A: 1) The influence of the buzzer switch on the radar module: → The buzzer switch will disturb the power supply. The buzzer and switch should be placed far away from the radar when designing the structure; →The buzzer switch and 10.525G signal will be mixed. The product software will shield the interference during design, and ignore the radar induction signal when the buzzer switch and indicator light flash; →The indicator light and 10.525G signal will be mixed, the sensor software algorithm should be updated, and the specific software version should be used for the scene with strong interference. 2) The influence of the relay on the radar module: →The on and off of the relay will cause a big disturbance on the power supply. When designing the structure, place the radar sensor far away from the relay, or make a shield on the structure; →The movement of the metal shrapnel of the relay is Doppler interference. When designing, the terminal software will shield the relay interference, ignoring
Q: Can CHZ provide installation instructions?
A: We provide product manuals, online guidance, video guidance, and on-site installation guidance and testing. Please communicate with us in advance, and we will negotiate to confirm a more appropriate guidance method to ensure the smooth completion of the project.
