Description
Technical Field
The utility model belongs to the technical field of the control system of outage, concretely relates to a control system for CT machine PC safe outage.
Background
All PCs of the existing CT machine system are powered off after a Recon PC (main PC) is powered off, so that the PCs except the Recon PC can be safely powered off to store data, and the rest PCs of the system cannot completely ensure that all PCs are powered off, thereby losing the data which are not stored in the PCs; under the long-term operation of the CT machine, the increasing number of times of the illegal shutdown of the PC increases the life and the damage rate of the PC.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a control system for CT machine PC safety outage can guarantee that all PCs are electrified safely down.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a control system for CT machine PC safety outage, includes power supply unit and PDU socket, be equipped with time delay outage module between power supply unit and the PDU socket, be connected through live wire and zero line between power supply unit and the PDU socket, time delay outage module includes start button, outage delay relay, contactor, start button's one end and live wire are connected, and start button's the other end and the one end of outage delay relay coil are connected, and the other end and the zero line of outage delay relay coil are connected, and the one end and the live wire of control contactor coil are connected, and the control contactor coil other end is connected with the one end of outage delay relay contact, and the other end and the zero line of outage delay relay contact are connected, and the control contactor of electrocuteeing is connected on live wire and zero line.
Further, the power supply device is a UPS power supply.
Furthermore, the live wire and the zero wire are also connected with circuit breakers.
Compared with the prior art, the beneficial effects of the utility model are that: when the system is shut down, the starting button is closed, the power-off delay relay coil is powered off in a delayed mode, and the contact of the control contactor is turned off in a delayed mode, so that the PDU socket is turned off in a delayed mode, all PCs can be safely powered off, and all PCs of the system can be safely stored with data and shut down legally.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution for a PC safety power-off control system of a CT apparatus:
a control system for safe power-off of a PC (personal computer) of a CT (computed tomography) machine comprises a power supply device and a PDU (Power distribution Unit) socket, wherein the power supply device is a UPS (uninterrupted Power supply), a time-delay power-off module is arranged between the power supply device and the PDU socket, the power supply device and the PDU socket are connected through a live wire and a zero wire, the time-delay power-off module comprises a starting button SB, a power-off time-delay relay KT and a contactor, one end of the starting button SB is connected with the live wire, the other end of the starting button SB is connected with one end of a power-off time-delay relay KT coil, the other end of the power-off time-delay relay KT coil is connected with the zero wire, one end of a control contactor KM1 coil is connected with the live wire, the other end of a control contactor; and the live wire and the zero wire are also connected with a circuit breaker QF.
When the system needs to be started, firstly pressing a UPS power supply button, then pressing a starting button SB, enabling a power-off delay relay KT coil to be electrified, enabling a power-off delay relay KT contact to be closed, enabling a control contactor KM1 coil to be electrified, enabling a control contactor KM1 contact to be closed, enabling a PDU socket to be electrified, and normally starting the system; when the power-off device is turned off, the starting button SB is turned off, the coil of the power-off delay relay KT is powered off in a delayed mode, and the contact of the control contactor KM1 is turned off in a delayed mode, so that the PDU socket is turned off in a delayed mode; the system power supply is turned off after the power failure of the Recon PC, and the power supply state of a period of time can be set by the power-on plug wire row of all the PCs of the system, so that all the PCs can be safely powered off, and the data can be safely stored and the system can be shut down legally.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
