Self-adaptive IO monitor

Abstract

The invention relates to a self-adaptive IO monitor, which comprises two controlled current sources, two uncontrolled current sources, a current-limiting switch controller and an external port, wherein the two controlled current sources are a controlled switch type current-limiting driver I and a controlled switch type current-limiting driver II respectively; the two uncontrolled current sources are an uncontrolled current source I and an uncontrolled current source II respectively; and the external port comprises a load driving power supply port, a load driving power output port, a working power supply input port of the self-adaptive IO monitor, a load state detection signal input end, a bidirectional port II and a common port, wherein the bidirectional port II serves as a bidirectional port shared by the load state detection signal output and the power output control signal input of the load drive; and the bidirectional port II Di / o of the self-adaptive IO monitor has bidirectional performance, does not need directional line control, and can reflect whether a load driven by the bidirectional port II Di / o exists to a control system through a load driving line in time.

Description

technical field [0001] The invention relates to an adaptive IO monitor, especially the signal level state detection and load drive control technology in the field of automatic control. It is an adaptive input and output control technology that does not require direction control lines and is suitable for artificial intelligence control systems. Intelligent transformation projects of domains and existing systems. Background technique [0002] In practical applications, for the application environment where the I / O resources of the controller are scarce, when the input or output interface resources of the microcontroller are not enough, it must be expanded through the peripheral circuit; when the expanded I / O port needs to be In the case of bidirectional operation, it is necessary to configure a direction control line to expand it through the peripheral circuit, which increases the consumption of the microcontroller's own I / O resources, which are already in short supply.

Problems solved by technology

[0004] In the process of project debugging, if it is found that there is insufficient quantity in one direction (input or output direction) in the previously reserved input or output quantity, although the other direction quantity (output or input direction) still has enough surplus quantity, it is still necessary The problem can only be solved by increasing the required direction of the equipment, resulting in the previously set plan having to be modified

[0005] For traditional control systems, the control output line cannot reflect the presence or absence of resistive loads, which is a serious defect for safety indications (the safety indicator lights cannot be reflected to the control system after being burned out), let alone Provide useful contributions to the era of artificial intelligence
