A power real-time monitoring circuit

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, and in particular relates to a real-time monitoring circuit of electric quantity. Background technique [0002] The battery is the power source for the detector circuit. Considering that the detector has a long warranty period and a large number of use, it is extremely inconvenient to replace the battery. Therefore, when the detector is designed, a larger energy battery is used to ensure that it will not be carried out during the warranty period. Battery replacement. However, the field work environment of the exploration project is complicated, and the operator's ability to standardize is different. It is inevitable that the illegal use of the geophone will occur, which will cause the waste of battery energy and shorten the battery life. As the engineering period of geological exploration, especially oil exploration, is long, ranging from dozens of days to several months, in order to ensure...
