Electronic system and warning apparatus thereof

Abstract

The invention provides an alarming device, comprising an isolating circuit, a first enabling circuit, a second enabling circuit and an output circuit; wherein, the isolating circuit receives a state signal and generates an adjusting signal according to the state signal; the first enabling circuit is electrically connected with the isolating circuit, receives the adjusting signal and generates a first enabling signal according to the adjusting signal; the second enabling circuit is electrically connected with the first enabling circuit, receives the first enabling signal and generate a second enabling signal according to the first enabling circuit; the output circuit is electrically connected with the second enabling circuit, receives the second enabling signal and outputs an alarming signal according to the second enabling signal.

Description

technical field [0001] The invention relates to an electronic system and its warning device. Background technique [0002] The functional requirements of electronic equipment are getting higher and higher, and the accessory equipments required are also increasing to meet the multi-functional requirements. Usually a processor is used as the control center of electronic equipment, and its processor is used for driving, controlling, detecting, indicating, warning and communication transmission. If the processor fails or the hardware is damaged due to external unclear factors, it will make the electronic device unable to control the operation of its peripheral accessories, such as the inability to control the operation of the radiator, resulting in ineffective Heat dissipation, even in severe cases, can cause the electronic device to crash. [0003] In order to improve the above situation, an alarm (alarm) device is usually installed in the electronic equipment to generate an ...

Problems solved by technology

[0012] However, when the processor 12 is in an abnormal state due to an open circuit or a power supply that is too high (high to Vdd), the state signal S02 is at a high level, so that the warning device 11 outputs the warning signal S03 at a low level, Cause the client system end 13 to judge that the processor 12 is still in a normal state, thus causing misjudgment

[0013] The above misjudgment occurs because the warning device 11 cannot clearly determine which device is in an abnormal state, so that the processor 12 cannot effectively control the operation of the electronic device 14, which may cause the electronic system 1 to crash.
