Abstract

The invention discloses a long-distance power supply circuit system with a detection circuit. The system comprises a main power source, a primary function module, a secondary function module and a distribution circuit; the main power source is connected with the primary function module and the secondary function module; and the distribution circuit is arranged between the main power source and thesecondary function module; the distribution circuit comprises a chip TPS62050, a power supply quality detecting circuit and a power supply distribution circuit; the power supply quality detecting circuit is connected with the pin LBI of the chip TPS62050; and the power supply distribution circuit is linked with the pin EN of the chip TPS62050. According to the system of the invention, the core function module and the secondary function module are both powered by the main power source, and therefore, problems such as the failure to startup and frequent restart which are caused by the insufficient power supply of end equipment can be solved.

Description

technical field [0001] The invention relates to a long-distance power transmission system, in particular to a long-distance power supply circuit system with a detection circuit. Background technique [0002] The long-distance power supply system refers to the system that uses cables or optical cables to transmit electric energy from terminal stations or manned relay stations to unmanned stations in long-distance wired communications, and supplies power to unmanned relay stations. With the development of science and technology, the requirements for long-distance power supply systems Higher and higher, the requirements for its stability and transmission distance are getting higher and higher. [0003] The main solutions for extending the power supply distance in the prior art are divided into three aspects: supply voltage to compensate for voltage loss during transmission; reduce load power consumption to reduce power requirements; increase cable cross-sectional area to reduce...
