Abstract

A data transmission instrument mainly solves the problem that a device special for performing oil metering control and effective data transmission in a metering room is not arranged in an oil field. The data transmission instrument is characterized in that a LPC 1766 single chip microcomputer, a FM 31256 chip, a MC 306 chip, a joint test action group (JTAG) interface circuit unit, a reset circuit adopting a CAT811S chip and a 12MHZ oscillating circuit are integrated on a main board of the data transmission instrument. An RS485 interface circuit unit, an RS232 interface circuit unit adopting a SIPEX3220 chip, an Ethernet network switching circuit unit with a ZNE_100T chip as a main chip, a relay output circuit unit adopting a ULN2003 drive chip and a universal serial bus (USB) interface circuit unit adopting a LM3526 chip are correspondingly connected onto a IDC20 socket and are connected with the LPC 1766 ARM single chip microcomputer through the IDC20 socket. The data transmission instrument can achieve an automatic oil metering control function, provides multiple data transmission modes and can improve the oil well metering accuracy and ensure the reliability of daily acquired data of oil field production.

Description

technical field [0001] The invention relates to an instrument used in a continuous oil measuring device in an oil field metering room. Background technique [0002] The continuous oil measuring device is a kind of equipment used in the metering room of the oil field. The main function of this kind of device is to automatically measure the daily liquid and gas production of the oil well for many times in a row, and at the same time input the data of the metering station and generate a report. The report mentioned here is the production data formed in the process of oil exploitation and production, and the summary and analysis of these data is an important work content of production management, and it is also an important means to ensure the normal, safe and economical operation of the oil field. At present, the data collection method adopted in the oil field is still manual collection, that is, the production and injection workers read the production parameters from each ins...
