GPRS Wireless Water Quality Sensor with RS-485 MODBUS Protocol 1% Accuracy and

KWS610A Fluorescent water quality MeasurementSystem Manual GPRS communication mode

1. System summary

"Water quality measurement system in GPRS communication mode" includes "water quality measurement terminal equipment in GPRS communication mode", "server management software" and "configuration line". It is used to periodically measure dissolved oxygen content, temperature values, longitude and latitude data, date and time information, and display these values in server management software.

Note 1: "Dissolved oxygen content measurement system in GPRS communication mode" is simply referred to as "system", as described below.

Note 2: "Dissolved oxygen content measuring terminal equipment in GPRS communication mode" is simply referred to as "terminal", as described below.

Note 3: The "server management software" called "software" is as follows.

Note 4: The “configuration line” of the short “line” is as follows.

The "terminal" is used to periodically measure the dissolved oxygen content and temperature values, and these measurements are transmitted to the "software" in the GPRS communication mode. Users can use the Software to view dissolved oxygen content values and manage these “terminals”.

"Software" is just a user's demo software. It's very simple, there are no powerful features to run many "terminals" at the same time. If you need a powerful large-scale system "software", please contact Xi'an Kaixi Optoelectronics Technology Co., Ltd.

“Line” is only used for user configuration “Terminal”, which is connected between “Terminal” and the RS232 serial port of the computer.

3. Technical standards and electricity consumption

• Communication frequency: GSM / GPRS 850/900/1800 / 1900MHz.
• Interface type: NPT1.
• Timed working time: 5 minutes to 1000 minutes (can be set).
• Additional functions: LCD, button, GPS.
• "Terminal" battery use time limit: For example, use the first battery "ER34615M", its capacity is 14.5AH, "system" working frequency works once every hour: GXPS609 (GPS) terminal can work for about 120 days.
• Battery model selection: It is recommended to use the first battery “ER34615M”. If the user wants to choose the battery by himself, please follow the battery standard as follows. Battery voltage: 3.0VDC~3.6VDC; maximum continuous output current: greater than 0.5A; pulse output current capacity: greater than 1A.
• Power supply lighting: The “terminal” can use a battery or an external power supply. See terminal structure diagram, the location of the external power supply in the "External Electrical Interface". In the interface, "1" is the anode and "2" is the cathode.

4. Maintenance Illuminate

1. Please insert a SIM card with GPRS serve Before use the “Terminal”. The SIM card must accord 800MHz, 850MHz, 1800MHz, 1900MHz.
2. Insure use the battery recommend. If “Software” show the “Terminal” battery capacity shortage, please replace new battery.
3. If communication disconnect between “Software” and “Terminal”, please check server, “Software”, “Terminal”, battery, and SIM card is whether normal or fault.
4. Avoid “Terminal” antenna near the metal and strong magnetic object.
5. If “System” work fault, and you don’t resolve the fault, please contact Xi’an Kacise. We don’t allow user take down and repair the “Terminal” for yourself.
