Method for delayed soft shutdown protection of wellsite data collector system

Abstract

The invention discloses a delayed soft shutdown protection method for a well site data collector system. The delayed soft shutdown protection method comprises an automatic delayed shutdown step and anexternal power-on automatic startup step, specifically, the power supply state information of a collector is monitored through a local operation management controller, a working condition state of acollector host is combined, when an external power supply is abnormal and the electric quantity of a built-in UPS battery pack reaches a set threshold value, the collector is automatically triggered to delay automatic soft shutdown and give a system alarm, stable operation and the service life of a host are more effectively guaranteed, reliable operation of a collector system is protected, and thecollector has a self-starting control step of electrified equipment. When the external mains supply is powered on normally, a signal is outputted to trigger the collector to be automatically startedand operated, and a powerful guarantee is provided for normal operation of a collector system and reduction of data discontinuity in the data collection process.

Description

Technical field [0001] The invention relates to wellsite data acquisition, and in particular to a method for delay soft shutdown protection of a wellsite data collector system. Background technique [0002] The data collector operates in an environment where there is no special supervision of the wellsite; the power supply of the wellsite power supply environment fluctuates; and the power supply of the collector is in a state of no mains power during the switching of the wellsite power supply line; and so on, the environment is for the conventional ordinary power supply industrial computer It is also very unfavorable, it is easy to cause hardware damage, data loss and other risks. There is a high risk of failure for the stable operation of unattended collectors. [0003] For this high-risk operating environment: the power supply unit of the collector adopts a wide-voltage, wide-frequency and high-efficiency AC power converter with input AC100~240V, 45~55Hz, and conversion efficien...

Problems solved by technology

[0002] The data collector operates in an environment without special supervision at the well site; the power supply of the power supply environment at the well site fluctuates from time to time; and the power supply of the collector is in a state of no mains power during the switching of the power supply line at the well site; such environments are not suitable for industrial computers with conventional power supplies. It is also very unfavorable, it is easy to cause hardware damage, data loss and other risks
