What are the advantages of using a wireless bridge for monitoring?

The following articles have been collected from the professional wireless bridge and solution provider Feng Runda. For reprint, please indicate the source.

Because wireless bridges can connect two or more networks to each other, they are often used in wireless monitoring to transfer monitoring data from one place to another, eliminating the need for cumbersome power wiring.

First, where do you need to use wireless bridges?

When doing monitoring projects, the problems of cable pulling and wiring cannot be avoided. If the monitoring scope is not large, the monitoring points are relatively centralized, and the wiring is relatively simple, the general cable monitoring will not have much difficulty. If the monitoring area is large, the points are scattered, and it is inconvenient for the cable to be wired, it will be a headache for cable monitoring. Using a wireless bridge to set up wireless monitoring is much simpler.

These places include:

1. Places where wired networks cannot be reached or where wiring costs are high: highways, environmental monitoring, forest fire prevention, street lamps, oil exploration, petroleum pipelines, electric power lines, and flood prevention and rescue.

2. Dangerous areas and places that are not easily accessible by supervisory personnel: flammable and explosive, hazardous areas, disease-infected areas, and other microbial hazardous areas.

3. Temporary structures and movable places: Temporary construction sites, temporary activity sites, convention centers, * investigations for temporary deployment, * field training, etc.

4. Locations where scattered locations are monitored: smart substations, reservoir river monitoring, and unattended monitoring of the engine room.

5. Monitoring sites with higher maintenance costs in the later period: elevators, docks, scattered townships, etc.

Second, flexible networking mode

The wireless bridge itself is very flexible and not too harsh on the environment. It can select transmission modes such as point-to-point, point-to-multipoint, and relay according to the environment.

1, point to point transmission

Point-to-point transmission mode is the simplest transmission mode, which is what we often call PTP. It is transmitted by a single device and then received by a single device. One-to-one transmission and reception is simple and direct. If the transmission distance is long, or the monitoring points are scattered, this situation is preferred for point-to-point transmission.

2, point-to-multipoint transmission

The point-to-multipoint transmission mode is developed based on the point-to-point transmission mode, and it often appears as one receiver to multiple transmitters. If the transmission distance is short and the monitoring points are relatively large and dense, or the front-end camera is analog, point-to-multipoint transmission can be used.

3, relay mode

The relay transmission mode is because the transmitting end and the receiving end block the microwave signal due to obstacles that cannot be avoided, so the relay device is added in the middle, so that the microwave signal is smoothly transmitted to the receiving end through the relay device. This mode is increased due to Transit equipment increases the cost of equipment, and there is a certain loss, so it will not be used when it is not necessary. If the transmitter and the receiver directly have relatively large obstructions or obstacles and do not want to change the original transmission path, then use the relay mode.

Third, other advantages

1, high flexibility

Now security requires no deadleg video surveillance, wireless monitoring is not limited by cables, has flexible scalability, can easily add new monitoring points at any location, and can change the location of the old monitoring, increasing the location uncertain Sex, so that the real implementation of security monitoring.

2, low cost

Only a one-time investment is required, and the wiring cost is low. There is no need for a professional construction team and no need to dig trenches. Wireless monitoring can get rid of the shackles of cables. It has the advantages of short installation cycle, easy maintenance, strong capacity expansion, and rapid cost recovery.

3, short construction period, easy maintenance

Wireline monitoring is often limited by the geographical environment and working environment, the construction period is very long, and even some areas of the wiring project simply can not be achieved. At this time, wireless monitoring was adopted to fundamentally free the cables and install them flexibly.

4, a wide range of applications

Can be widely used in a wide range of distributed safety monitoring, traffic monitoring, industrial monitoring, home monitoring and other fields. Such as ATMs, bank tellers, supermarkets, factories and other wireless monitoring, nursing homes, kindergartens, schools to provide remote wireless monitoring services.
