Embodiment 1

[0032] This embodiment provides an automatic restart device of a microcomputer device. This embodiment takes the automatic restart device of a relay protection device as an example to describe in detail.

[0033] Such as figure 1 As shown, the automatic restart device of the relay protection device includes: a double-coil magnetic latching relay, and the double-coil magnetic latching relay includes a restart coil CQDJ, a reset coil FWJ, and a first normally closed contact CQDK1 and a second normally closed contact Contact CQDK2.

[0034] The signal trigger terminals of the restart coil CQDJ and the reset coil FWJ are connected to the CPU signal output terminal of the relay protection device through the control loop. The first normally closed contact CQDK1 is connected to the power terminal of the relay protection device through the power plug-in, and the second normally closed contact CQDK2 is connected in series in the control circuit of the restart coil. Wherein, the secon...

Embodiment 2

[0047] In this embodiment, on the basis of Embodiment 1, the restart coil CQDJ, reset coil FWJ, and the first normally closed contact CQDK1 and the second normally closed contact CQDK2 are integrated on a PCB board, which is integrated in the relay Inside of protection devices or other microcomputer devices that require automatic restart.

[0048] The circuit connections of the restart coil CQDJ, the reset coil FWJ, the first normally closed contact CQDK1 and the second normally closed contact CQDK2, and the working principles are the same as those in the first embodiment.

[0049] Embodiment of automatic restart control method

[0050] Still taking the automatic restart of the relay protection device as an example, the automatic restart control method of the relay protection device is as follows:

[0051] 1. The CPU of the relay protection device monitors in real time whether there are any abnormal signals such as "device abnormality", "device alarm", "SV signal disconnectio...

Abstract

The present application relates to an automatic restart control device and method of a microcomputer device. The automatic restart control device includes a double-coil magnetic latching relay, and the double-coil magnetic latching relay includes a restart coil, a reset coil, and a first normally closed contact and the second normally closed contact, the reset coil and the reset coil are connected to the control output end of the microcomputer device through their respective control loops, and the first normally closed contact is connected in series in the power circuit of the microcomputer device, so The second normally closed contact is connected in series in the control loop of the restart coil, and the second normally closed contact is a power-off holding contact. The application can realize the automatic restart of the microcomputer device, save manpower and material resources, improve work efficiency, and solve the current problem that the restart of the microcomputer device requires manual on-site operation and low work efficiency.

Description

technical field [0001] The application belongs to the technical field of relay protection, and in particular relates to an automatic restart control device and method of a microcomputer device. Background technique [0002] At present, the relay protection device of the substation has been fully computerized, that is, computer protection. During the operation of the relay protection device, some disturbances or environmental factors may cause abnormal phenomena of the relay protection device, such as: device abnormality, device alarm, SV signal disconnection, GOOSE signal disconnection, etc. These abnormal phenomena may lead to protection blocking and make the substation lose protection, which must be dealt with in time. However, many years of operating experience have shown that most of these abnormal phenomena disappear after the device is powered off and restarted, that is, the device can return to normal by restarting the relay protection device. [0003] At present, m...
