采用故障安全技术的系统被称为“故障安全系统”或“Fail-safe system”，这类系统主要应用于对安全性要求极高的场景中。它们由经过特殊设计的故障安全CPU和故障安全模块共同组成，以确保在故障发生时能够迅速响应。故障安全型CPU通过了TüV（一个德国的安全认证机构）的严格认证。这意味着，在发生故障时，这类CPU能够确...
五分钟读懂故障安全(Fail-safe)系统 技术的不断进步使得工业控制系统的持续稳定运行能力得到了显著提升。然而,设备故障仍是不可避免的。为了保障设备和操作人员的安全,在故障发生时,我们需要一种特殊的技术来介入,这种技术被称作“故障安全技术”或“Fail-safe technology”。 简而言之,故障安全技术的主要功能是在设备...
Fail-Safe I/O to Achieve Ultra Low System PowerThe disclosure provides an input/output (IO) circuit powered by an input/output (IO) supply voltage. The IO circuit includes a cutoff circuit that receives a first invert signal, the IO supply voltage, a bias voltage and a pad voltage. An ...
随着技术的发展,工业控制系统的连续无故障运行时间得到了很大的延长。但是设备总有出故障的时候,当故障发生时,人们希望有一种技术,能保证设备和人身的安全,这种技术,称为“故障安全技术(Fail-safe technology)”。 具体来说,故障安全技术,是当故障发生时,能将设备导向安全的状态或位置的技术。故障安全技术最早应用于...
This paper describes the method to prevent the leakage current and function fail at power-off of an Input and Output(I/O) pad, and suggests using circuit to control NMOS driver. This circuit is operated as sleep mode at power-on and operated as wake-up mode (fail-safe) at power-off....
