Caimore GPRS/3G/4G wireless remotecontroller RTU for environment protection

solution

Abstract: This paper provides a method to realize based on 2G, 3G, 4G wireless

acquisition and transmission terminal communication technology of water treatment

remote monitoring program, and gives a brief description of the wireless data

acquisition and transmission terminal RTU application in water treatment. Through

practical application, the ideal effect is obtained。

Key words: 3G, 2G, 4G; wireless collection and transmission; wireless acquisition

and transmission terminal RTU; just RTU;

1. Background

With the rapid development of urban construction and the continuous progress of

the economy, people's living standards continue to improve, urban environmental

protection requirements are also increasing. To this end the relevant government

departments to strengthen the pace of sewage treatment, and increased control efforts.

In order to grasp the environmental protection departments around the need to

monitor water quality and environmental information management, the need for the

relevant water quality within the jurisdiction of the use of remote monitoring

technology for monitoring and control to comply with water quality and sewage

treatment discharge standards.

that provides real‐time data collection, transmission, remote management and control

functions such as sewage effluent environmental protection departments to achieve

water quality remote monitoring and control of management.

2. Introduction

According to the environmental protection department of the various multi‐field

trips and understanding, and we deal with cases of successful projects around the

sewage, the general environmental protection department under the jurisdiction of the

sewage treatment facility, to be located in the township area or village streets sewage

treatment plant. Various sewage treatment facilities, sewage treatment related sensing

means, such as collection and transmission required pH, DO, water temperature, water

and so on, this kind of data sensing device is typically digital data with a wireless remote

control terminal RTU RS232 device or RS485 direct connection transmission. Also

because of the need for wastewater treatment, as well as on‐site fans, pumps,

automatic control systems and other equipment, when these major equipment failures,

real‐time feedback to the relevant information, and to be able to be remotely start and

close. This requires RTU remote monitoring and control wireless terminal device to have

information on the monitoring and reporting capabilities of the device, while the

transmitter signal and must have a standard level of a signal transition functions, and

RTU devices cloud management platform software with remote control function.

Based on this, the use of 2G / 3G / 4G wireless data transmission technology,

provides a fixed IP or dynamic IP (available binding domain) and port number, these

parameters are set in the server Caimore wireless communication RTU remote server

application based on broadband cable networks the control terminal device, use it to

automatically resolve the domain name address, to connect to the service side of the

RTU cloud device management platform software that provides real‐time data collection,

transmission, remote management and control functions such as sewage effluent

environmental protection departments to achieve remote monitoring and control of

water quality management, is a good set of remote automatic monitoring platform

program.

3. System Composition

The program system consists of wireless RTU Remote Terminal equipment, GPRS /

3G / 4G wireless communication infrastructure network and cable Internet and related

communications equipment, servers and cloud RTU device management platform

software, etc.

1, each water quality sensing devices, fans, pumps, automatic control systems;

2, RTU remote monitoring and control wireless terminal device;

3,2G / 3G / 4G wireless networks and wired Internet;

4, the server;

5, RTU cloud platform device management software;

4. Networking Applications

4.1 connected devices: various sewage treatment facilities pH, DO, water

temperature, water sensing device by RTU RS232 or RS485 interfaces for communication

with Mao only one connection;

4.2 Server deployment: in the monitoring center this end, assign a rack‐mounted

servers as the server hardware. Server hardware unit for summer cloud RTU device

management software platform, the platform software B / S structure, receiving and

sending data for managing the acquisition and transmission of sensing means;

4.3 Erection data channels: the server this end of the application using a fixed IP

address, open a port number has not been used in the router this end connected to the

server, the IP address and port number to configure the server to Caimore RTU

communication, when when RTU related equipment is enabled, data transmitted

through this channel;



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


4.4 Transmission of data: When enabled RTU, namely through 2G / 3G / 4G

network and the monitoring center server establish a transparent transmission channel,

then RTU that is able to receive data from each sensor device transmitted by wireless

remote RTU itself data transparent transmission function, intact send data to the

monitoring center server, the use of cloud RTU device management platform software,

which can also send control commands to the RTU, in order to achieve real‐time data

collection, processing, control and statistics.

6.System functions

Remote automatic monitoring platform system is mainly to achieve the following



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


functions:

6.1, RTU remote monitoring and control wireless terminal device:

RTU remote monitoring and control wireless terminal device integrates the analog

signal acquisition, digital input, digital output, counting and wireless data

communications in one of the high‐performance measurement and control devices

support Ethernet communications, serial communication, RS485 communications and

4G / 3G / 2G wireless data communication in one.

Direct access to a variety of sensors, signal transmitters standards, instruments and

other analog signal output, level signal, dry contact, pulse signals.

Can be realized on pH, DO, water temperature, water and other real‐time

monitoring data.

The fan is connected to each pump, through remote monitoring platform

management software PWM function or relay function can be realized on pumps, fans

remote control to start or stop working.

6.2 RTU cloud platform device management software features

RTU cloud platform device management software has user management, system

management, acquisition and control, remote upgrades, remote configuration,

proactive alerting and reporting functions active.

Caimore wireless communication with the RTU Remote Terminal Equipment series

equipments. It enables data acquisition and wireless transmission of various types of

sensors, remote monitoring and control and management functions.

According to the different management objects, set different access privileges such

as having only basic operator acquisition and control, remote configuration, query,

statistics and other basic functions, in addition to having these operations administrator

function, but also with senior management, remote upgrades, registered management

and user management functions.

You can set whether to allow the initiative to report the action is set to report

contents, report network mode (phone alarm system + alarm), reporting intervals,

reported receiving phone number information and other conditions. When the

connection with the fans, pumps or other automatic control system equipment,

real‐time anti‐fault information should

Through remote monitoring platform management software PWM function or relay

function can be realized on pumps, fans remote control to start or stop working.

Having query statistics function, monthly or time period for monitoring data query

and summary reports are formed, can be achieved for every facility the number of

sewage treatment day, month, and other statistical form reports for management

decision‐making use.
