Abstract: This paper provides a design principle and implementation scheme of environmental

monitoring system based on 3G/4G network, and briefly describes the implementation method

of 3G/4G wireless transmission applied to environmental monitoring. Through practical

application, the ideal effect is obtained.

Key words: 3G/4G; router; Internet; environmental monitoring;

1. Background

Environmental protection data acquisition system is a pollution source monitoring system

composed of pollution source emission monitoring point and monitoring center. The system of

pollution sources of automatic sampling, the on‐line monitoring of the main pollution factor;

grasp the city pollution discharge and pollution emissions, monitoring data automatically

transmitted to the environmental monitoring center; by the monitoring center computer for

data collection, collation and synthetic analysis; monitoring information is transmitted to the

Environmental Protection Bureau, Environmental Protection Bureau as the decision center of

the system and of monitoring information obtained from monitoring center station of analysis,

research, promptly made decision management, increase the intensity of management.

Compared with the wired communication mode, the 3G/4G wireless communication mode is

very flexible, it has the advantages of flexible networking, easy expansion, low operation cost,

simple maintenance, high cost performance and so on. Therefore, it can be used to solve the

problem of real‐time transmission of monitoring data of pollution source by 3G/4G wireless

transmission.

2. Solution advantage

Based on the 3G / 4G service platform on environmental information collection and

transmission system based, to achieve environmental protection information acquisition, the

wireless data transmission can make full use of the existing network, shorten the construction

period, lower construction cost advantages, and equipment installation convenient and simple

maintenance.

3G/4G wireless environmental pollution sources online monitoring system has the following

characteristics:

1, real time:

Caimore wireless data transmission equipment has the characteristics of real time online, no

time delay, and the data of multiple monitoring points can be received and processed

simultaneously without the need of wheel inspection. It can be very good to meet the

requirements of real‐time data acquisition and transmission system.

2, low construction costs:

Due to the use of public network platform, without the construction of the network, only need

to install the equipment can be good, low cost of construction;

3, a wide range of monitoring:

Construction of environmental protection information collection and transmission system

requires a wide range of data communication coverage, unlimited expansion, access to the site

without restrictions, to meet the needs of the mountains, towns and cross regional access.

Because of the large number of environmental information collection points, distributed in the

province, some environmental information collection point is located in the remote area, and

geographical location is scattered.

4, has a good scalability:

Due to the current public network has covered in most areas, there is no blind area, can realize

online monitoring a wide range of environmental information collection and transmission

system to meet the coverage requirements.

5, the transmission capacity of the system:

To achieve real‐time connection and each environmental information collection station

environmental protection center. Due to the environmental information collection points many

system requirements can meet the needs of burst data transmission, 3G/4G technology can well

meet the needs of the transmission of bursty data.

6, low communication costs:

The monthly billing, low operating costs.

3. Solutions introduction

Since the 3G/4G communication is the IP address of the data packet communication network

based on the host computer monitoring center fixed IP address configuration, each data

acquisition point by Xiamen caimore router and the host computer communication.

(a) system composition

Site monitoring points over pollution source information automatic collection of data

acquisition module, through RS232, 485 or RJ45 interfaces and Xiamen Caimore industrial

router and transparent data transmission, each monitoring point use is connected with the

control center through the 3G / 4G network, the pollution source data acquisition point support

24 hours real‐time online, realize information collection points 24 hours collection and

transmission of environmental information data.

a. In practice, if the next collection point and not a lot of collection points and very large

volumes of data dispersed situation, you can take center‐to‐multipoint network applications.

Users need to install the appropriate service center server software can be carried out in the

center of the multi‐network applications. Wi‐Fi service throughout the system, the user does

not need to understand TCP / IP, UDP protocol, can be realized under the program do not

change the case of existing Wi‐Fi devices, and networking simple and reliable, and can save you

valuable time and have investment, can be used for long distance communication or control. In

this case, the data transmission distance unrestricted, flexible networking, communication can

ensure stability, to avoid loss of important data. The practical application of (1) as



-----------------------------------------------------------------------------------------------------------


follows:

Figure (1)

B. in practical application if the acquisition point is relatively concentrated, and acquisition point

of relatively more and less amount of data can take the way of grouping, each group shared a

wireless data transmission, in communication data acquisition equipment and wireless data

transmission between each combination is 485 total lines, in this case to facilitate networking,

post operational fee less can guarantee a small amount of data is not lost, and to reduce the

number of equipment, cost savings, but each data acquisition device preferably not more than

30 units, data acquisition equipment and wireless data transmission between the even line can

not be too far away. Since 485 is a half duplex mode, to meet the low efficiency of full duplex

communication case.

The actual application as shown in figure (2) is as follows:

Figure (2)

C. In practice, if more concentrated collection points and collection points and relatively more

cases may also take the following grouping method. In this case, using the first capture device

servers and serial devices (serial server) connected in each group serial device server (serial

server) and having a plurality of switches connected to RJ45 interface and then switch and

wireless router . Data during communication serial device server (serial server) data acquisition

equipment needs to be sent for conversion to take advantage of Ethernet transmission to be

received from the Ethernet data to be converted to the use of serial transmit data acquisition

equipment. The following figure as a wireless router, since the wireless router has only one RJ45

interface, so you have to be expanded into a plurality of switch RJ45 interface. In this scenario

the serial port server can flexibly arrange its distance and data acquisition equipment and

switches in accordance with the requirements of the construction site and technology. Due to

the use of serial device server to avoid the shortage due to the FIG. (2) 485 employed in this

half‐duplex communication brought about by lower operating costs and late, due to the use of a

serial server, the entire program cost ratio Figure (1) low, but higher than that of FIG. (2).

the software support platform, super memory, embedded TCP/IP protocol stack with independent

intellectual property rights. To provide users with high‐speed, stable and reliable, the data terminal is

always online, a variety of protocols to convert the virtual private network. For network traffic

control users, product support voice, SMS, data triggered on the line as well as automatic

disconnection of the function. At the same time also supports dual data center backup, as well as

multiple data centers to receive data synchronization and other functions. Company product
