Shanghai Ruicheng Electric Co., Ltd. is mainly engaged in the BeiDou GPS BeiDou clock, and the products are in stable operation in nearly ten thousand domestic and foreign industries. Now we will summarize the equipment installation, routine maintenance and solutions. Shanghai Ruicheng Electric Co., Ltd. is mainly engaged in the BeiDou GPS BeiDou clock. The products are in stable operation in nearly 10,000 sites at home and abroad. Now we will summarize the precautions for installing the BeiDou clock of the GPS.
1. Q: How to distinguish the GPS Beidou clock antenna?
Answer: Put the white mushroom head of the antenna on the outside, and connect the BNC head of the antenna feeder end to the interface of the Beidou clock backplane antenna of the GPS. Turn on the power and enter menu 6 to display the star count. When the value is greater than 0, it indicates the antenna. Stars can be received and used safely.
2. Q: What if the GPS Beidou clock antenna is not long enough?
Answer: The length of the antenna cable is strictly designed according to the antenna gain, and the connector must not be cut, lengthened, shortened or installed. Otherwise, the receiving effect will be seriously affected and no signal will be received. Therefore, when ordering, measure the actual wiring length of the antenna in advance and purchase an antenna suitable for the field length.
3, GPS Beidou clock antenna lightning protection how to consider?
A: Under normal circumstances, high-rise buildings will be used for lightning protection. White mushroom heads are placed at the roof/window/terrace/balcony, etc. It will not exceed the maximum lightning protection measures of the building. When the antenna is installed on the roof, it should be placed in the building. Lightning rod lightning protection range, as long as the field of vision is enough, the distance from the roof is as small as possible. If you are still worried about lightning strikes, you can add a special antenna arrester. The arrester is installed between the GPS clock host and the antenna. It does not affect the effect of star reception. Before the thunderstorm season arrives, it must be carefully checked whether the lightning protection system is sound.
4, GPS Beidou clock antenna how to install fixed?
A: Our standard equipment will be equipped with mounting brackets, expansion screws and other accessories. The connection mode between the mounting bracket and the antenna is thread type. There are three fixing holes below the mounting bracket. The expansion holes can be used to fix the hole at the top of the building.
GPS Beidou clock antenna installation tips:
1. Mount the antenna mushroom head on the antenna bracket and fix it on the top of the house or on the platform. Ensure that the antenna mushroom head has the largest possible field of view (360 degrees sky) and no obstructions are allowed.
2. Antennas should avoid obstacles to the antenna beam, such as hillsides, trees, high-rise buildings, towers, and high-voltage transmission lines. There should be enough horizon in the direction of the main beam of the antenna, and the widest possible angle of view should be in front of the antenna. The general requirement is to use the antenna base point as a reference, and the angle formed by the highest point of the obstacle is less than 10 degrees.
3. All antennas are standard, and they must not be cut or randomly stacked. Otherwise, satellites cannot be guaranteed.
4, before the laying of the antenna to connect the GPS clock host to test the next star effect, so that laying a good cable and then measuring the star effect eliminates a lot of trouble.
5, when the star is not received when the antenna for more than a few places to try the effect to distinguish between the antenna itself is the problem or the location of the antenna installation.
