7 Introduction to working principle of

monitor

The monitor consists of parts involving sampling, filter, sample gas decrease

humidity/constant temperature control, sample gas density analysis, data

acquisition/digital filtering, dynamic data graphic display, data

storage/inquiry/communication and automatic power supply mode selection etc.

7.1 Sampling

The sampling part consists of air line, filter, suction pump and flow regulator etc. In

this part, the ambient air is introduced by suction pump through the filter and delivered

to sensor air chamber before being exhausted via monitor discharge hole as per flow

of 300mL/min separately.

7.2 Filter

Zero air filters: filter the sample gas when calibrating the zero.

Dust removal filter: remove dust particles in sampling gas.

7.3 Sample gas density analysis

It is made up of such electrochemical sensors as SO2 sensor etc. These sensors

detect the density of sample gas flowing through air chamber and output the current

signal corresponding to density of measured gas.

7.4 Data acquisition/digital filtering

The CPU-controlled data acquisition circuit collects multiplexed signals output by the

sensors instantly and processes the abnormal data with digital filtering so to ensure

correct and reliable acquired data against eliminating influences of various

interferences.

7.5 Dynamic data graphic display

The monitor applies 640480 dpi graphic LCD, which can visually display various

monitoring data and figure as well as monitor working status and provide Chinese or

English menu in man-machine dialogue with friendly interface.

well before setting, turn off monitor first then take SD card in or out; SD card memory

is 512M, if memory is not enough, please delete trashy data, avoid to error when save

data.

8.1 Sensor polarization

To satisfy requirements for normal operation, the monitor shall always keep the

sensor in polarized state. When the sensor has been replaced or the polarization

process has been interrupted, you can calibrate or measure the monitor only after

24-hours continuous sensor polarization.

The monitor is equipped with built-in lithium battery (15V). When the external power

supply fails to provide power for the monitor, it will automatically switch to battery to

provide polarizing voltage for sensor. Under conditions of normal operation, the

lithium battery shall be ensured with sufficient electricity so to keep the sensor always

in polarized state.

8.2 Charging built-in lithium battery

The monitor is supplied with built-in lithium battery or external AC mains. When being

connected to external mains, it will automatically shut off the built-in battery.

When the lithium battery needs to be charged, it can be in charging state through

inserting the power plug into the socket without opening the power supply switch.

8.3 Calibrating and monitoring zero and range

The monitor can only be calibrated and monitored after at least 24 hours continuous

polarization.

8.3.1 Calibrating zero

The sample gas for calibrating zero can adopt zero calibrating standard gas or clean

ambient air. Connect the monitor to the zero calibrating filters and perform calibration

as per instructions displayed in screen. See attached Figure II.

Fill the high-purity nitrogen into gas bag. Note that the gas bag shall not contain other

residual gases otherwise it will influence the accuracy of calibration.

8.3.2 Calibrating range

22

When calibrating range, adjust the standard gas flow at 300ml/min and operate as per

instructions displayed in screen.

See attached Figure III.

(1) First, fill high-purity nitrogen and standard gas into gas bag separately.

(2) Prepare standard-proportion gas with high-accuracy gas mixer (See Operational

Instructions for Gas Mixer).

(3) Inlet the prepared standard-proportion gas into air-inlet opening and perform

calibration.

Attention: please dont calibration sensor if monitor is available, or inlet high density

calibration gas due to sensor goes back normal monitoring status need long time.

8.3.3 Environmental monitoring

When perform environmental monitoring, locate the monitor in the monitored

environment or connect the air-inlet opening to sampling pipe and operate as per

instructions displayed in screen. Properly connect AC220V power supply.

9 Attention

1. The monitor shall be protected from rain or moisture.

2. Never operate or calibrate the monitor at places close to EMI source.

3. The sensor contains acid solution and do not damage it when replacing. In case of

acid solution in the sensor leaking to your skin due to improper operation, you should

flush your skin with running water for ten minutes promptly and then get for medical

assistance in time.

4. Never repair or disassemble the monitor without permission. If the monitor fails or

the sensor expires, we will provide you with high-quality after-sales technical service.

10.3 Configuration

10.3.1 Configuration connection

Before configuration, its necessary to connect the IP MODEM with the configure PC

by the shipped RS232 or RS232-485 conversion cable as following.

10.3.2 Configuration introduction

There are two ways to configure the IP MODEM:

Configuration software tool: All the settings are configured through the shipped

software tool. Its necessary to have one PC to run this tool.

Extended AT command: All the settings are configured through AT command, so

any device with serial port can configure it. Before configuration with extended AT

command, you should make IP MODEM enter configure state.

29

The steps how to make IP MODEM enters configure state, please refer to appendix.

The following describes how to configure IP MODEM with the configure software tool.

At the same time, it gives out the corresponding AT command of each configuration

item.

10.3.3 Run the configure tool: IP Modem Configure.exe

The Serial Parameters column shows the current serial port settings. To configure IP

MODEM, please choose the correct serial port which connects to IP MODEM, and the

baud rate is 115200 with no parity, then open the serial port. If the button text is

Close, it shows the serial port now has been opened. If the text is Open, you

should open the port first. When the port opened, the Output Info column will display

Port (COM1) Has OpenedPlease Re-Power the IP MODEM, Waiting IP MODEM

Enter Configure State...

10.3.4 Re-power IP MODEM

30

After Re-power IP MODEM, The configure tool will make it enter configure state. At

the same time, the software will load current settings from IP MODEM and displays on

the right configure columns. Its now ready to configure.

10.3.5 Configuration

10.3.5.1 Data service center settings

Settings on this page are the parameters related to Data Service Center (DSC).

Data Center Number

IP MODEM supports two Data Service Center methods to transmit data.

Main and Backup: IP MODEM always tries to connect with the Main DSC. If fails to

connect with Main DSC, it will connect with Backup DSC at once

NoteIf no Backup DSC exists, please configure the Backup DSC same as Main

DSC.

Multi Data Service Center: IP MODEM can connect with at most five DSC at the same

time. All the multi DSC can receive the same application data.

If the Data Center Number is 1, IP MODEM work in Main and Backup DSC method.

When Data Center Number is greater than 1, IP MODEM works in Multi Data

Service Center method

31

AT command:

AT+SVRCNT=x

x: Data Service Center number

Note: every AT command is terminated with a enter character.

Main Center Addr + Port:

IP Address and Port of the Main DSC, Its better to set the port greater than 1024.

AT command of the Main DSC IP address or domain name:

AT+IPAD=xxx

xxx: The IP address or domain name.

AT command of the Main DSC port:

AT+PORT=xxx

xxx: The port value

Backup Center Addr+Port:

IP address and port of the Backup DSC

AT command of the Backup DSC IP address or domain

AT+IPSEC=xxx

xxx: The IP address or domain name

AT command of the Backup DSC port

AT+PTSEC=xxx

xxx: The port value

Multi DSC Configuration

32

When Data Center Number is greater than 1, this setting is valid. For example

setting the Data Center Number as 3, Main Center, 2nd Center, 3rd Center work as

these three DSC

AT Command of the 2~5 DSC IP address or domain name

AT+IPADn=xxx

n is 1~4 correspond to center 2~5

xxx: The IP address or domain name

AT Command of the 2~5 DSC port

AT+PORTn=xxx

n is 1~4 correspond to port of center 2~5

xxx: The port value

Example:

Set IP address of center 3 as 166.111.8.238, and port 5001, the AT command is as

following:

AT+IPAD2=166.111.8.238

AT+PORT2=5001

Main and Backup Center DNS Server

When the DSC Internet access uses domain name, Its necessary to set DNS server

resolving the DSC domain name. When the Data Center Number is 1, Main and

Backup Center DNS Server is used to resolve the Main center and Backup center

correspondingly.

AT command of Main Center DNS server:

AT+DNSSVR=aaa.bbb.ccc.ddd

aaa.bbb.ccc.ddd: The DNS server IP address(must be IP address.

AT command of Backup Center DNS server:

33

AT+DNSSV2=aaa.bbb.ccc.ddd

aaa.bbb.ccc.ddd: the DNS server IP address

Center 2~5 DNS Server

When the IP MODEM work in Multi Data Service Center method and the centers use

domain name, 2~5 DNS server is used to resolve center 2~5 correspondingly.

AT command of 2~5 DNS Server

AT+DNSSVRn=aaa.bbb.ccc.ddd

n is 1~4 correspond to center 2~5 DNS server.

aaa.bbb.ccc.ddd is the DNS server IP address

aaa.bbb.ccc.ddd is DNS service IP address (Must be IP address).
