Oil well load intelligent monitor terminal device

Abstract

The invention provides an oil well load intelligent monitor terminal device. A voltage transformer is in a parallel connection with a current transformer and then is respectively and sequentially in a series connection with a signal conditioning circuit, an analog / digital (A / D) conversion device and a central processing unit (CPU), the CPU is connected with a storage and provided with a 485 port, the CPU can convert the data into a wireless signal which is sent out through a general packet radio service (GPRS), a master station server of an upper computer is connected with a signal receiving device, a supervisory control computer is in a wired connection with the master station server, and a capacitor is in the series connection with a terminated line. The oil well load intelligent monitor terminal device has the advantages that the structure is simple and safe, the operation is convenient, the monitoring effect is good, and the electric power theft can be effectively prevented.

Description

technical field [0001] The invention relates to a monitoring terminal device, in particular to a monitoring terminal device for power data collection. Background technique [0002] For a long time, some units have used the theft of electric energy as a means of profit, and adopted various methods, ignoring or underestimating electricity, in order to achieve the goal of not paying or paying less electricity bills, resulting in a large loss of national electric energy and staggering losses. This behavior has seriously damaged the legitimate rights and interests of power supply companies, disrupted the normal order of power supply and utilization, and posed a serious threat to the safe use of electricity. By measuring the current on the high-voltage incoming line side, calculate the high-voltage power and electricity, compare it with the power and load on the low-voltage side, or count the usual electricity consumption, and alarm the sudden increase in current and electricity c...
