Method and system for controlling unibus equipment

Abstract

The invention discloses a unibus control system for saving hardware resources and improving the control efficiency on unibus equipment, comprising an microprogrammed control unit (MCU), an electric potential control device, a unibus and inibus equipment, wherein the output end of the MCU is connected with the receiving end of the electric potential control device; the receiving end of the MCU is connected with the output end of the electric potential control device; the output ends of the MCU and the electric potential device are connected with the unibus equipment through the unibus; the electric potential control device is used for outputting a signal to the unibus equipment through the unibus under the condition that the MCU requires to output the signal, wherein both the signal and a signal output by the output end of the MCU are signals of a high level or a lower level; and under the condition of receiving the signal transmitted by the unibus equipment through the unibus, the level of the output end of the electric potential control device is same as that of the signal transmitted by the unibus, so that the receiving end of the MCU receives the signal transmitted by the unibus. The invention also discloses a method realized by using the system.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method and system for controlling a single bus device. Background technique [0002] In single-board designs with high power consumption, temperature sensors are usually used to monitor high-heat devices or high-heat areas. If the detected temperature exceeds a preset threshold, it will report to the management unit for temperature adjustment. [0003] In the existing advanced telecom computing architecture (Advanced Telecom Computing Architecture, ATCA) board design, the temperature sensor chip uses a single-wire digital temperature sensor from Dallas (Dallas), and through a common input of a commonly used 8-bit microcontroller AT89C51 The / output pin (General-Purpose input / output, GPIO) reads and writes the temperature sensor. see figure 1 As shown, a temperature sensor needs to be connected to one GPIO, so the microcontroller (MCU) must provide more GPIOs for use when ...

AI Technical Summary

Problems solved by technology

[0004] Since one temperature sensor needs to be connected to one GPIO, when the MCU needs to transmit commands to multiple temperature sensors, it must repeatedly generate multiple commands and transmit them to the temperature sensors through each GPIO, thus occupying more software resources and repeating The process of generating multiple commands also consumes some time and power consumption

[0005] To sum up, the existing technology has the problem of consuming hardware resources, software resources and power consumption, and the control efficiency of the temperature sensor is not high.
