Retevis RT97 Repeater Small Business Application: Zhengzhou National Wetland Park of Yellow River Private network communication solution. This is a use case for RT97 Repeater. It mainly solves the problem of timely voice communication in the park.
Zhengzhou Yellow River National Wetland Park,One of the 20 wetland park pilots approved by the state.Zhengzhou Yellow River National Wetland Park covers an area of 2390 hectares.The location in the plan is,The south side of the Yellow River channel between the Yellow River pontoon and the Yellow River Highway Bridge in the Huiji District of Zhengzhou City.
The Zhengzhou Yellow River National Wetland Park consists of six functional zones:
Popular science mission area, recreation and entertainment area, beach area exploration area, ecological conservation area, Yellow River farming and cultural area and comprehensive service area.The Zhengzhou Yellow River National Wetland Park Planning Area has a typical river wetland ecosystem.Rich in animal and plant resources,It is important that a large number of migratory birds stop, winter or breed here every year.
The problems facing the park now:
1. Safety protection of river embankments:The entire park is in the Yellow River channel.The soil of the Yellow River bed is soft,It is easy to collapse,It is more prone to collapse during the flood season.
2. Safety protection for water projects:There are some boats on the Yellow River.There are also a lot of passengers on the boat.Doing a good job in water rescue is also one of the priorities.
3. Park workers communication:The land area of the park is 2390 hectares.It is 2.5km long and east.Voice communication is often required between employees.Radios are needed to increase productivity.
4. Radio operation certificate problem: Because the park management staff are mostly residents nearby,There is no radio operating certificate.
It is more appropriate to use an exempted radio product.
5, emergency center: There is an emergency center at the main entrance of the park.Responsible for medical rescue in the park.A dedicated emergency communication channel is required.
The plan is as follows:
The landform is relatively flat,Simple functional requirements: clear voice communication.The hand-held terminal uses an exemption walkie-talkie.The number of employees in the management group, employee group and first aid group is 20~30.The number of people used is small.
And they are all inside the park.Use one channel.The signal covers the entire park and the Yellow River.The longest span is 2.5km.The repeater station uses RT97 to fully meet the demand.
There is a sealing ring at the seam of the RT97 Repeater shell.Both the power interface and the antenna interface are waterproof and sealed.RT97 Repeater is not afraid of wind and rain, sunlight erosion,The RT97 Repeater is ideal for outdoor use.The RT97 Repeater is 31x28x17cm and is very compact.The RT97 Repeater weighs only 1705g.The most one Repeater is very light.These make it much easier to build a repeater system.
Antenna erection position,The center of the park is west to the bird watching station.The birdwatching platform is built for steel profiles.3 stories, about 12 meters high.The antenna support rod is 10 meters high.The total height of the antenna is 22 meters.
Transit station communication radius estimation:
The communication covers a radius of 3.4km.The longest distance of communication can reach 6.8km.Complete coverage of the entire park and its surroundings.
Program related equipment:
The whole project is not only simple to construct,It is also very convenient to maintain.RT97 Repeater can pre-store 16 channel information.And each channel can be set to receive and transmit sub-audio independently.After commissioning,The working channel can be modified directly by pressing the button.The Changan Up arrow looks at the sub-audio settings of the current channel.
