Remote controller for high precision DC power supply

Abstract

The invention relates to a power source remote controller based on eight-bit single chip, wherein said high-accuracy direct-current power source remote controller comprises: a single chip (1) whose address bus (10) is connected to the address decoder (3) and the data memory (4); the invention is characterized in that: it also comprises a decode output of address decoder (3) to be used as the chip select address of data memory (4), digit / analogue convert circuit (5), multi-path independent analogue / digit convert circuit (6), state input circuit (7) and switch output circuit (8); the eight-bit data bus (9) of single chip (1) is connected to the data memory (4), the digit / analogue convert circuit (5), the multi-path independently analogue / digit convert circuit (6), the state input circuit (7), and the switch output circuit (8); the serial port of single chip (1) is connected to the communication interface circuit (2). The invention can realize remote distribution control on the high-accuracy high-stability direct-current stable-current or stabilizing power source, to realize relative control targets, with better anti-interference ability.

Description

Technical field: [0001] The invention relates to a power supply remote controller based on an 8-bit single-chip microcomputer. Background technique: [0002] At present, the controller based on 8-bit single-chip microcomputer only monitors the operating status of the power supply, and cannot adjust the output current / or voltage. The output remote voltage reference resolution is low or the long-term stability is poor. The value readback accuracy is low, which cannot meet the needs of high-precision and high-stability DC steady-current power supply or voltage-stabilized power supply, such as: the long-term stability of output current or voltage is less than 1×10 -4 Remote control requirements. Invention content: [0003] The purpose of the present invention is to avoid the disadvantages of the prior art and provide a high-precision DC power remote controller. Under the control of the main control computer, the output current or voltage value of the high-precision and high-...
