Embodiment 1

[0040] The pipeline pressure data remote wireless transmission system provided by the embodiment of the present invention, such as figure 1 As shown, the system includes a pressure acquisition unit 11, a terminal 12, a mobile monitoring center 13, and a fixed monitoring center 14; wherein,

[0041] The pressure acquisition unit 11 is used to acquire and convert the first pressure signal of the pipeline, and send the first pressure signal to the terminal 12; wherein, the first pressure signal is an analog current signal of 4-20mA .

[0042] The terminal 12 is used to perform analog-to-digital conversion processing on the received first pressure signal to obtain a second pressure signal; filter the second pressure signal according to a preset sampling period to obtain a third pressure signal; Packing and encrypting the third pressure signal; sending the third pressure signal to the mobile monitoring center 13 or the fixed monitoring center 14 through a wireless network; wherein...

Embodiment 2

[0066] Compared with Embodiment 1, this embodiment also provides a data remote transmission method, such as Figure 5 As shown, the method includes the following steps:

[0067] Step 501, collecting and converting the first pressure signal of the pipeline;

[0068] The first pressure signal of the pipeline is collected and converted by the pressure acquisition unit, and the first pressure signal is sent to the terminal; wherein, the first pressure signal is an analog current signal of 4-20 mA. Wherein, the pressure acquisition unit may be a pressure transmitter.

[0069] Step 502: Perform analog-to-digital conversion processing on the first pressure signal to obtain a second pressure signal; filter the second pressure signal according to a preset sampling period to obtain a third pressure signal; The signal is packaged and encrypted; the third pressure signal is sent through a wireless network;

[0070] In this step, the terminal performs analog-to-digital conversion proces...

Abstract

The invention provides remote data transmission system and method. The system comprises a pressure acquiring unit and a terminal, wherein the pressure acquiring unit is used for acquiring and converting a first pressure signal of a pipeline; the terminal is used for processing the first pressure signal by analog-digital conversion to obtain a second pressure signal, screening the second pressure signal according to a preset sampling cycle so as to obtain a third pressure signal, packaging and encrypting the third pressure signal and then transmitting the third pressure signal to a mobile monitoring center through the wireless network; the mobile monitoring center is used for storing the received third pressure signal, displaying the third pressure signal through a first display screen, and sending the third pressure signal to a fixed monitoring center, wherein the fixed monitoring center is used for storing the third pressure signal from the mobile monitoring center to a database and displaying the third pressure signal through a second display screen. With the adoption of the system and method, data transmission can be performed through wireless network.

Description

technical field [0001] The invention relates to the technical field of oil and gas storage and transportation, in particular to a data remote transmission system and method. Background technique [0002] In oil storage and transportation, pipelines are the key to ensure the normal transportation of oil and natural gas and the normal operation of oil and gas pipelines. The development of pipeline transportation industry is of great significance for petroleum and petrochemical enterprises to further optimize the allocation of internal crude oil resources, accelerate the utilization of foreign crude oil resources, reduce operating costs, participate in international competition, and improve the quality of national economic operation. [0003] Pipeline pressure monitoring is an extremely important task before or during operation of oil and gas pipelines. At present, the conventional pipeline pressure monitoring method is to transmit the data collected by the pressure transmitte...
