Application of remote monitoring in oil well

The distribution of oil wells is very wide, so it is impossible to use the wired

communication mode for remote control. After years of development, wireless communication technology has been very mature and widely used in various industries. The function of DTU module has been modularized and standardized.

The wireless monitoring system for oil wells is composed of sensors, wellhead controller, DTU data transmission unit, real time database server, WEB server, and monitoring terminal. The sensors of oil well working state are mainly temperature sensor, pressure

sensor, motor current sensor, voltage sensor of pumping unit load, displacement sensor and transformer primary side current sensor, they will transform the working status into the corresponding voltage or current value and send to the wellhead controller. The well head controller collects the signals of various sensors and gets the working condition of the oil well. The wellhead controller will send the collected signals to the DTU through the serial port, and then the DTU will send it to the remote Internet data center through the wireless network. Its typical application networking is shown as Figure 1 -4.

Step 6 Refer to the "3.4 TCP+DDP transmission mode (single center)" to carry out the relevant

configuration and connection.

To enter the test command "123456" in the string input box of the serial port tool, click “send".

Observe DSC Demo and serial port information. Table shows channel data alarm success.

Level data channel alarm verification

Step 7 The verification process of the level data channel alarm is the same as the "B data channel alarm verification", but in the expansion parameter configuration, it is necessary to strictly follow the protocol level alarm configuration format.

Step 8 For example:

<fnt=alarm;trg=gpio;rpt=sms;io=4;jmp=up;vld=4;send=123;nums=13512345678

,13312345678>



4 FAQ

4.1 H7000 series DTU is unable to communicate with external devices

Symptom

H7000 series DTU is unable to communicate with external devices.

Failure cause

The causes of the failure are as follows:

The area where the device is unable to provide 2G, 3G, 4G services, 2G, 3G, 4G services are not fully covered in the region, "DSC's IP address" and "DSC port" configuration is not correct

Solution

If the area where the device is unable to provide 2G, 3G, 4G services, 2G, 3G, 4G services are not fully covered by the region,

Please contact the network operator for a reasonable solution. If the "DSC's IP address" and "DSC port" are not configured correctly, configure the

parameters "DSC's IP address" and "DSC".

4.2 Unable to connect to the tool using the DTU Tool configuration parameters

Symptom

PC is unable to connect to the tool when configuring the parameters.

Failure cause

The causes of the failure are as follows:

The computer serial port connected to the device is not working properly. The H7000 terminal is not in the same place as the configuration computer.



The time of "RTU connection timeout" of the tool box parameter is shorter.

Solution

If it is connected to the serial port of the PC machine is relatively fragile, serial port can not

work, please replace the PC machine or replace the serial Export. The computer serial port connected with the device can not work normally, and the

connection line between the connecting device and the PC machine is detected. If the H7000 terminal is not in the same place as the PC, please make sure that the ground is

in the same place. If it is a short time on the management tool, the connection device parameter RTU

connection timeout (default is 50 seconds), To modify it for a longer period of time, it is generally recommended to change to 60

seconds. DTU system start-up time of about 18 seconds, after the start of the device will consume a

second time for the detection of the serial port of 10 consecutive spaces. If the test is successful, it will switch to the AT state. Otherwise run the application directly. The device also needs some time to switch to AT.

4.3 DTU send text messages to the phone display garbled

Symptom

DTU send text messages to the phone display garbled.

Failure cause

The reason is that the DTU message encoding format configuration error, configured as

"7BIT".

Solution

Configure DTU SMS short message sending code for "8BIT" or "UCS2".

4.4 DTU cannot resolve DSC domain name

Symptom

DTU cannot resolve DSC domain name, log information is as follows:

00:10:41[ERROR]failed to get host by name [88864288.vicp.net] ...

00:11:12[ERROR]failed to get host by name [88864288.vicp.net] ... ；

Failure cause

Log shows the domain name parsing fails, indicating that the operator can not resolve the

DSC domain name DNS address IP.



Solution

Define the "IP address" in the "run parameters" parameter "DNS" for "8.8.8.8"".

The DNS address 8.8.8.8 can be used in any public network environment, parsing fast, and relatively s table.
