Small-power multi-channel fast-charging intelligent control terminal with double CPUs (Central Processing Unit)

Abstract

The invention relates to a small-power multi-channel fast-charging intelligent control terminal with double CPUs. The small-power multi-channel fast-charging intelligent control terminal comprises a communication main control board composed of a main CPU and a field main control board composed of slave CPUs. Wherein the master CPU communicates with the slave CPU through a CAN (Controller Area Network) bus; the slave CPU is electrically connected with a plurality of intelligent equipment cells of different independent channels through different I / O ports, and is used for controlling the charging process of the intelligent equipment cells to realize an electric control lock function; the intelligent equipment cell is used for storing intelligent equipment needing to be charged. The small-power charging cabinet has the beneficial effects that the use condition of the small-power charging cabinet, the current and voltage of each charging box, the use time of the charging box, the power of the charging box, the use cost, the use stopping command, various use states, payment connection and the like can be obtained in real time. By means of the Wi-Fi module, a user can carry out remote control through a mobile phone terminal, remote intelligent charging control is achieved, and safe and reliable electricity utilization is ensured.

Description

technical field [0001] The invention relates to the field of intelligent device charging, in particular to a dual-CPU low-power multi-channel fast-charging intelligent control terminal. Background technique [0002] With the rapid development of power electronic conversion devices, people use a wide variety of charging terminals, resulting in endless fire problems. [0003] As a mobile platform ship, due to its limited space, centralized electrical equipment, and independent micro-grid, the potential safety hazards caused by charging equipment are bound to be greater. According to the regulations, the crew is prohibited from carrying electric heating appliances such as electric cups on board for use, and it is strictly forbidden to connect and pull the power cord without permission. For some public electrical appliances, there are designated safe special sockets or additional dedicated lines. Therefore, it is very necessary to reduce the laying of wires and cables on the sh...
