Nowadays, in the scenes of factory management, modern agriculture, and smart city, the use of wireless communication modules is increasing. The standard installation is one of the important conditions for wireless modules to work stably for a long time. Reasonable operation can reduce maintenance. And time cost.
1，Attentions when installing the wireless module
a , Lightning protection and waterproof measures. Thunderstorms often have transient high-voltage and high-current discharge effects in the air and time. Wireless modules that do not have lightning protection according to requirements are easily affected by lightning. Especially equipment that needs to be equipped with antennas. Once it is attacked by lightning, the communication link will be Interruption, high voltage is introduced into the wireless module system will also damage the internal control circuit, causing irreversible damage. Lightning protection and water isolation is an effective measure to protect the wireless module from lightning strikes and ensure the normal operation of the wireless module communication link. Therefore, install professional lightning arresters as much as possible according to the actual situation
b , Have a reliable grounding. Grounding is an important factor affecting the normal operation of communication equipment. Its function is as follows: reliable grounding reduces noise and other interference to wireless module communication equipment, improves the working stability of electronic components of communication equipment, and ensures protection of electronic components in communication equipment. Electrostatic high voltage, damage of transient discharge pulse; good grounding enables the communication equipment to obtain good shielding effect, avoiding external electromagnetic interference, etc.
c , Antenna should have a reasonable installation layout
* Depending on the transmit power of the module (or station) used, the distance of the transmitted distance is chosen to suit the appropriate antenna type. Commonly used antennas have spring antennas, and can also be used with SMA adapters, elbows, folding rods, suction cup antennas or other high-gain omnidirectional or directional antennas.
* Read the antenna instructions carefully before installation. Are there any special requirements? Check the frequency band of the antenna and check whether the power tolerance meets the requirements.
* The erection height of the outdoor antenna is determined according to the needs and actual conditions. The distance of the transmitted signal transmission should be considered, the surrounding interference situation and the loss of the feeder line. It is not the higher the antenna erection
* The grounding of the outdoor antenna base should be good, the installation should not be tilted, the installation must be firm, and it can resist wind, corrosion and strong temperature changes
2 , Attentions when using the wireless module
a , A group of wireless modules that communicate with each other should be kept in the same frequency band, and the channel and air rate should be set the same. Otherwise, data loss and garbled reception will occur
b , The wireless module should be avoided in extreme environments such as high temperature humidity, dust, and low temperature.
c , Choose a suitable DC stabilized power supply, it is best to use a power supply that can resist interference, small ripple and strong load capacity to ensure that the wireless module can work stably and stably.
d , Standard installation and use of wireless modules allows the product to perform at its best. Read the instructions carefully and operate in strict accordance with the requirements to reduce unnecessary misuse and improve efficiency.
