Reservoir remote monitoring system

Case background

In recent years, with the progress of society and the development of economy, science and technology, people's living, working and production levels have been greatly improved. Reservoirs play a vital role in people's production and life, such as supplying domestic water, agricultural irrigation, industrial water, drought and flood control, etc. reservoirs play a vital role for us. The safety monitoring of reservoir involves the stable development of society, but it mainly depends on the monitoring of personnel, which is not only a waste of manpower, but also very inconvenient to manage. Therefore, in this context, the monitoring system of monitoring reservoir safety and early warning through wireless GPRS came into being.

Scope of application

The system is suitable for remote monitoring and management of reservoir monitoring, meteorological monitoring, geological security and natural disaster measurement.

system composition

The reservoir remote monitoring system is mainly composed of dispatching center, rainfall monitoring center, communication platform, rainfall remote measurement and control terminal, measurement and measurement (tipping bucket rain gauge, water level gauge, anemometer, osmometer, etc.) equipment and power supply equipment (solar panel or municipal power supply is required for real-time online mode).

Composition of reservoir remote monitoring system

System functional features

The rainfall and water level monitoring personnel can remotely monitor the rain gauge signal, water level gauge signal, wind speed signal, solar panel voltage, etc., and can remotely set the return time. When the GPRS network cannot be connected, it can be stored locally and sent back to the server again when GPRS is reconnected. When it is used for water level monitoring of reservoirs and lakes, if the water level exceeds the upper and lower limits and the seepage pressure exceeds the limit, it will automatically send early warning messages.

A. Hardware Introduction (rtu6100)

1. Wide voltage power supply range: 7v-30v, suitable for industrial occasions;

2. With RS232 and RS485 (when 232 is also converted to 485, there can be two 485 channels), it can be easily configured and RS485 network can be established;

3. 6 channels of ad analog input (12 bits), the input voltage is 0-30V, and it can also measure 4-20mA industrial current signal. Ad analog is suitable for collecting various sensor signals;

4. 6-way relay output control and 4-way optocoupler input and output control (the number of input and output bits is optional), which can be used for input and output occasions, such as motor startup;

5. Transmission supports a variety of protocols. Our company's self-defined protocol and Modbus Protocol (ASCII, RTU, Modbus TCP) perfectly support, and Modbus protocol perfectly supports configuration;

6. Data transmission adopts GSM module, which can realize the following functions:

a) GPRS disconnection automatic reconnection;

b) Up to 6 central servers can be connected at the same time as required;

c) Support the addressing mode of fixed IP, domain name resolution and APN private network;

d) Support TCP, UDP, PPP, ICMP, DNS, FTP and other protocols;

e) Reduce the cost of wiring and the trouble of construction;

f) Support SMS data transmission and SMS parameter configuration;

g) Support phone and SMS wake-up function;

7. Support special software for local and remote parameter configuration and maintenance;

8. Support local and remote firmware upgrade;

Low power acquisition

1. Ultra low power consumption, standby current as low as 25-35 µ a, suitable for long-term work in the field;

2. Automatic wake-up mode is adopted, and 3ua-4ua can be achieved in standby mode;

3. Collect sensor information regularly and store it in flash;

4. Connect with the server regularly and upload the collected data;

5. Support server automatic timing;

6. Be able to identify rainy season and non rainy season;

7. It can remotely configure the return time in rainy season and non rainy season;

B. Software function

Remote monitoring of rainfall, water level, wind speed, dam seepage pressure and other signals.

Remotely set the system working mode (low power consumption, normal working mode).

Support the storage and historical record query of various monitoring information, control information, alarm information and operation information.

Generate various data reports and data curves.

Real time display of rainfall and water level

The device list on the left shows the information of current online and offline devices. When the device is connected to the network, it will enter the "online device list" from the "offline device list". If the device is not online for a long time, it will enter the "offline device list" from the "online device list";

The upper right corner displays the equipment number, user name, contact person, telephone, fax, mobile phone, SIM card number, address and other information;

The upper left corner displays rain gauge, water level gauge, anemometer, solar panel and other information (or dam seepage pressure);

The curves of rain gauge, water level gauge, anemometer and solar panel are displayed in real time under the window;

The middle text prompts the current equipment login time and the last time of collecting and returning data;

Historical records of rainfall and water level

Users can search history according to time period;

The history record will be drawn on the window in the form of curve, and the history record can be displayed under the window in the form of list. Through the history record, the equipment operation status and relevant trend can be viewed;

The history records queried at the same time can be exported to excel;
