Abstract
The invention provides a voltage control method and device of a space particle radiation detector, the space particle radiation detector comprises a processing chip and a plurality of DAC chips, each DAC chip has multipath output, and the processing chip executes the following method: receiving a voltage control instruction of the voltage of the space particle radiation detector; when the voltage control instruction accords with a preset correct rule, identifying a voltage control type of the voltage control instruction; determining the working state of the DAC chip corresponding to the voltage control type; when the working state is an idle state, setting the working state of the DAC chip corresponding to the voltage control type as a busy state; the voltage control rule corresponding to the voltage control type is adopted to control the voltage of the space particle radiation detector, and the voltage is transmitted to the output end corresponding to the corresponding DAC chip, compared with a device adopting the DAC chip with only one path of output, a large number of input / output channels do not need to be provided, the cost of processing the chip is reduced, the circuit area is reduced, and the power consumption is reduced. And the overall hardware cost is reduced.
