Intelligent measurement and control module applied to ground DC power supply

Abstract

The invention belongs to an intelligent measurement and control module and specifically relates to an intelligent measurement and control module applied to a ground DC power supply. The module includes a one-chip microcomputer used for calculation. The one-chip microcomputer is connected with an external signal conditioning circuit electric signal through an AD conversion function. The one-chip microcomputer is connected with an external keyboard input circuit through a keyboard input function. The one-chip microcomputer is connected with a liquid-crystal display driving circuit through a display function. The one-chip microcomputer is connected with a power module circuit through a power control function. The one-chip microcomputer is connected an external alarm circuit through an alarm judgment function. The one-chip microcomputer is connected with an external RS422 interface circuit through a serial port. The one-chip microcomputer is connected with an external Ethernet interface through a network communication function. The one-chip microcomputer is connected with an external storage calling module through a storage calling function. The beneficial effects of the module are that the intelligent measurement and control module applied to the ground DC power supply is capable of satisfying independence of a ground power supply and use of access networks and meeting short range and remote control and power supplying demands of a ground measurement and control system.

Description

technical field [0001] The invention belongs to an intelligent measurement and control module, in particular to an intelligent measurement and control module applied to a ground direct current power supply. Background technique [0002] According to the requirements, the design of the intelligent measurement and control module can realize the intelligentization, modularization, networking and good transplantation of the ground DC power supply of the re-entry telemetry ground system. It can also measure and control the ground power supply through the host computer while meeting the power supply requirements of the ground system. , to alarm and deal with the abnormal situation of the ground power supply, to realize near-table keyboard control and liquid crystal display for a single ground power supply, and to realize the long-distance and short-distance measurement and control requirements of the ground system. [0003] The ground DC power supply is mainly for the telemetry sy...
