Abstract

The invention, which belongs to the technical field of battery detection, discloses a real-time power monitoring circuit comprising a current sampling circuit, a timing monitoring circuit and an output resistance circuit. The current sampling circuit is connected with a detected battery and the timing monitoring circuit respectively and the output resistance circuit is respectively connected with the timing monitoring circuit and a detection port. The output resistance circuit consists of an analog switch chip and a plurality of resistors; the plurality of resistors are connected in series to form a resistor string; the two ends of the resistance string are connected with the detection port; a control terminal of the analog switch chip is connected with the timing monitoring circuit; and a switching terminal of the analog switch chip is connected in parallel with the plurality of resistors. According to the real-time power monitoring circuit, the residual energy of the battery is monitored in real time by using a single-chip microcomputer intelligent technique; on-line obtaining of the residual power value of the battery is realized by a simple way; a problem that the consumed power and the rest of service life of the power supply battery of equipment can not be determined can be solved; and the reliable guarantee is provided for successful exploration engineering.

Description

technical field [0001] The invention belongs to the technical field of battery detection, in particular to a power real-time monitoring circuit. Background technique [0002] The battery is the power supply source for the geophone circuit. Considering that the geophone has a long warranty period and a large number of uses, it is extremely inconvenient to replace the battery. battery replacement. However, the field operation environment of the exploration project is complex, and the standardization ability of the operators is different. It is inevitable that the geophone will be used illegally, resulting in a waste of battery energy and shortening the battery life. Due to the long period of geological exploration, especially oil exploration, ranging from dozens of days to several months, in order to ensure the smooth progress of the exploration project, it is necessary to clarify the remaining energy and remaining usage of the detector power supply battery at any time before...
