1 Product Introduction
1.1 Summary
H7000 series DTU products provide a wireless communication link between terminal
equipment and data service center (platform) for customers by 2G, 3G, 4G cellular
networks.
H7000 2G DTU is a wireless DDN network data communications product based on
GPRS/GSM/CDMA. H7000 4G DTU is another wireless data communications product
based on 4G network (TDD-LTE, FDD-LTE, down compatible with
WCDM/EVDO/TD-SCDMA/EDGE).
Besides, H7000-V5X and H7000-V6X are with dual serial port function, in which one port
for debug, another for data transfer, so that the debugging information can be view while
the data port is sending data.
Hongdian H7000 series DTU also passed the third party certification EMC and EPRI EMC
four level test.
1.2 Product orientation
H7000 series DTU is positioned as an industrial wireless transmission equipment, in order
to solve the problem of remote transmission of data in various industries.
H7000 series DTU products correspond to the transport layer products in the Internet of
things architecture. According to the different needs of customers, this series of products
can meet the needs of different applications (wherein, our embedded products can meet
the requirements of embedded applications), and meet the requirements of low power
consumption.
Its application is very extensive, for example:
Power system distribution network monitoring and large customer meter reading
Monitoring of tap water and gas pipeline
Environmental monitoring stations located in factories, streets and fields
Hydrological monitoring and flood control, drought and wind data collection

Power industry applications (remote meter reading)
The power remote meter reading system is composed of the distribution center located in
the electric power bureau and the meter data collection point in the residential area. It
makes use of the existing wireless network to transmit data through wirele ss network of
wireless operators. All the meters of residential area are firstly connected to the electricity
meter concentrator through the RS-485 serial port, and the concentrator meter is
connected to the DTU (2G/3G/4G transparent data transmission unit) via the RS-232 port,
to transmit the data to the data distribution center via the cellular network. Typical
applications such as Figure 1-3 network shows. Typical application network is shown as
Figure 1-3.

Application of remote monitoring in oil well
The distribution of oil wells is very wide, so it is impossible to use the wired
communication mode for remote control. After years of development, wireless
communication technology has been very mature and widely used in various industries.
The function of DTU module has been modularized and standardized.
The wireless monitoring system for oil wells is composed of sensors, wellhead controller,
DTU data transmission unit, real time database server, WEB server, and monitoring
terminal. The sensors of oil well working state are mainly temperature sensor, pressure
sensor, motor current sensor, voltage sensor of pumping unit load, displacement sensor
and transformer primary side current sensor, they will transform the working status into
the corresponding voltage or current value and send to the wellhead controller. The well
head controller collects the signals of various sensors and gets the working condition of
the oil well. The wellhead controller will send the collected signals to the DTU through the
serial port, and then the DTU will send it to the remote Internet data center through the
wireless network. Its typical application networking is shown as Figure 1 -4.
Figure 1-4 Oilfield application
Integrated application of wireless environmental monitoring
In the environmental monitoring, it is necessary to monitor the pollution emission points,
and most of the monitoring data need to be sent to the back-end server of the

management center. Because the monitoring points are scattered, the distribution range
is wide, and most of them are located in the areas with bad environment, it is the best
choice for the environmental protection departments to use the wireless network to
transmit data. Pollution source monitoring equipment can capture the image, pollution
emission data and alarm information, and send to multiple environmental monitoring
departments through the wireless network, to achieve timely management of sewage
units or individuals, greatly improving the work efficiency of the environmental protection
department. Its typical network is shown as Figure 1-5.

spray system software platform, monitoring and control to achieve the remote equipment
running status, maximally solve the inconvenience the hot weather brought factors. Its
typical network is shown as Figure 1-6.

Application of water resources monitoring system
We Hongdian corporation through years of water conservancy industry customer support
and understanding , accumulate a lot of experience, independent research and develop a
remote data terminal equipment (hereinafter referred to as RTU). Real time hydrological
information acquisition of various modern sensor technology with the equipment, such as
rainfall, evaporation, water level (tide, underground water level), flow (velocity, water),
water quality, realize the information collection, processing, storage and retrieval function,
and the data will be collected real-time information through the wireless communication
channel to the management system that is convenient for the user to timely
understanding of rainfall, hydrological and other hydrological information. It is
characterized by fast, accurate, large amount of information, and can be seamlessly
connected with the third party system. Typical application is shown as Figure 1-7.
