Because of the opportunity to host the Asian games in 2010, with a "culture of guangzhou, lingnan ancient county, international will be in guangzhou and energetic guangzhou, sports, ecological and landscape in guangzhou city" features "Asian city" image, began the construction of ASIAN GAMES TOWN in the panyu district of guangzhou city, guangdong province.

Our company participated in the ASIAN GAMES TOWN D block wireless monitoring of construction projects. As is known to all, the difficult problems is : engineering construction safety, fire prevention, security work.

Compared with the difference between cable monitoring and wireless monitoring:

project	Cable transmission	Wireless transmission
wiring	Wiring cumbersome ,requires a lot of manpower and material	No need wiring
expansibility	Weaker .For some reason, the original wiring reserving the port is not enough to use, add a new user will have to rearrange cables, cumbersome, long construction period and other trouble	Stronger. Only need to increase the microwave transmitter and receiver and front-end equipment
Attenuation	For some reason, the original cable attenuation phenomenon appeared to replace or difficult to replace the cable, new wiring or replace the tedious work, need a lot of manpower and material resources.	Have no attenuation, if equipment aging, only need to change the equipment of the attenuation part
difficulty construction	High construction difficulty, need to dig a hole bury cable laying, wiring to threading, and through walls and many unknown factors (such as electricity, water), etc., make the construction more difficult.	Low construction difficulty, quick construction speed, less manpower, engineering to complete high quality.
mobility	very low, if you want to move to laying cable again, it is difficulty.	very high, in some special cases, the front-end devices only need to move in a range.
Cost	High installation cost, equipment cost is low, but high maintenance costs.	Installation cost and maintenance cost is low.

The project of ASIAN GAMES TOWN, SUNTOR company with 2 sets of 2418SZ and wireless video instruction control machine do wireless remote video monitoring transmission on the two cranes. In the hundred meters, leave out the trouble of wiring. If the project finished, after removed can continue to use at the next project.

Integrated Wireless Monitoring Solutions

In the traditional monitoring systems, generally analog camera , they must be connected to the engine room through the video cable. And when network technology to fully integrate into people's living and working environment , network cameras use more and more popular. Contrast with analog cameras , network cameras can be connected to the engine room through a ubiquitous network cables and switches.

Like network cameras replace analog cameras , wireless network began to develop and replace wired networks Network connection can use wireless transmission equipment , in the long distance , obstructions etc. environment .Using wireless transmission connected to the engine room, used in conjunction with the wired network that allows monitoring project becomes more convenient , monitor a wider range.

for example: Crane monitoring, forest fire monitoring, reservoir monitoring, parks security monitoring and etc .

Wireless monitoring system advantages:

◇ Crane works , avoid trenching pipe , nail groove Wired。

◇ Scenic monitor, do not destroy the decorative , easy to install

◇ Mobile monitoring，such as Vessels , vehicles, mobile stage and etc.

◇ A large area monitoring，such as Forest fire prevention, monitoring reservoirs , rivers monitored etc，Can save time and low costs.

Now , the wireless monitoring is a wireless LAN network by wired + wireless transmission composition, That is connected via a wireless bridge , and then connected through the switch and the network cable to the engine room to increase WIFI network coverage module can also provide wireless Internet access for laptops, cell phones , tablet PCs and other devices.

一. The main application：
The main application areas of wireless monitoring includes the following sites monitored：

★ Community wireless monitoring	★ Bank of wireless monitoring	★ Entertainment wireless monitoring	★ Supermarkets wireless monitoring
★ Campus wireless monitoring	★ Office area wireless monitoring	★Builders wireless monitoring	★Wireless monitoring forest fire
★ Scenic wireless monitoring	★ Parking Wireless Monitoring	★ Wireless monitoring ports	★ Aquaculture wireless monitoring
★ Driving wireless monitoring	★ Logistics Park wireless monitoring	★ Wireless monitoring power industry	★ Highway wireless monitoring
★ Water Conservancy wireless monitoring	★ Wireless monitoring of wind power plants	★ Oilfield Mining wireless monitoring	★ Car shipboard wireless monitoring

1.Open and beautiful environment , wireless is more suitable

2.Monitoring points widely distributed, large monitoring range , lower wireless costs.

 

the greater the distribution of monitoring points ,The farther the distance ,Wireless monitoring more suitable. Depending on the specific application .Engineering is usually pull the network cable and wireless transmission combined,

Large site wireless monitoring project (ST-58T8G wireless bridge application)

1. site description:

To make sure the works go on wheels and the devices safety, the large Site need to monitor 24 hours every day. So adopt the video monitoring. The site need install HD network bolt camera,10 points, and the customer want night vision 80m(client’s requirement: purchase by himself)

From camera to local monitor room distance up to 1km,monitor room can monitoring the site hold time, can dispose in time when happened accident. In consideration of use the wired video monitor the wire will pull-apart by car. So take wireless video transmission equipment for remote wireless monitoring, wireless transmission multiple high-definition video images.

A total of 20 cameras, each lever has 2 cameras, each lever using two switch, so can use two cameras summarize a transmit. Between The control room and the camera have 1km range, when install wireless video transmission equipment requires the use of high back-end wireless receiver equipment for transmit and receive unobstructed and can receive multi transmitter signals. So use 1point to 3points, 1point to 3points, 1point to 4 points, achieve 20 roads transmission of video signals. The rear end, the use of the switch aggregates radio signal receiver, and finally into the storage device to a monitor.

2. Customer demand:

Establish an advanced video surveillance security management system is to strengthen the science building construction safety, improve project management efficiency, prevent unauthorized persons broke into the site, causing accidents and property damage. Due to limitations of the construction environment, equipment, materials, inadequate safety management and some employees of self-protection awareness is weak, is not suitable for traditional wired monitoring methods, but they must be installed on-site video surveillance system.

3. Wireless video monitoring project

According to the customer requirements, Our company provided a Digital wireless video monitoring system. Adopt the 5.8G frequency ST-58T8G and 5.8G frequency ST58T8G-N industrial wireless digital equipment

The front end of each lever transmit to monitor room, Adopt 1point to 3points, 1point to 3points, 1point to 4 points, achieve 20 roads transmission of video signals receiver, Switchboards summary, Transmission to the control room ,NVR storage, can watch by the monitor. The NVR can control the cameras rotation.
