Abstract
The utility model provides a circuit board screw lock safety monitoring system, it includes: circuit board, logic level detection module and alarm module, the circuit board is equipped with the screw on it, the screw has at least two and connects foot, one of them it connects to connect the foot logic level detection module, foot ground connection is connected to remaining other, and logic level detection module, its further with alarm module connects and is used for listening connect the level state of foot and control when the high level state alarm module sends alarm signal. Therefore, the utility model discloses circuit board screw lock safety monitoring system can not twisted at circuit board screw in time infories the user when having locked.
Description
[technical field]
The utility model is a kind of circuit board screw lock safety monitoring system.
[background technology]
At present for industrial products, in transportation, have vibrations, and cause screw to come off, loosen; Assembling process occurs that screw is forgotten and twists lock, fixing insecure phenomenon.This situation probably causes screw to come off, and gently then main board work is unstable, needs dismounting again, wastes time and energy, heavy then cause main plate short and burn out, and wastes time and energy more expensive.
In view of this, the utility model provides a kind of circuit board screw lock safety monitoring system, and it can be notified user in time when circuit board screw does not twist and lock.
[utility model content]
Fundamental purpose of the present utility model is to provide a kind of circuit board screw lock safety monitoring system, and it can be notified user in time when circuit board screw does not twist and lock.
For reaching above-mentioned purpose, the utility model provides a kind of circuit board screw lock safety monitoring system, and it comprises: circuit board, logic level detecting module and alarm module;
Described circuit board, which is provided with screw, and described screw has at least two connecting pins, and wherein connecting pin described in connects described logic level detecting module, other connecting pin ground connection remaining; And
Described logic level detecting module, it is connected the level state for detecting described connecting pin further and controls described alarm module when high level state and sends alerting signal with described alarm module.
Preferably, described logic level detecting module is baseboard management controller.
Compared with prior art, the utility model circuit board screw lock safety monitoring system knows in the screw of circuit board whether have lock screw by the level state of the screw on described logic level detecting module circuit for detecting plate, and control alarm module sends alerting signal when not locking screw, notify that user's circuit board exists screw and do not lock situation by this, so that user locks the screw of circuit board in time, guarantee that circuit board normally works.
[accompanying drawing explanation]
Fig. 1 is the functional-block diagram of a kind of circuit board screw lock of the utility model safety monitoring system.
[embodiment]
Refer to shown in Fig. 1, a kind of circuit board screw lock of the utility model safety monitoring system comprises circuit board 1, logic level detecting module 2 and alarm module 3.
Described circuit board 1 is provided with screw 10, and described screw 10 has at least two connecting pins 100, and wherein connecting pin 100 described in connects described logic level detecting module 2, other connecting pin 100 ground connection remaining.
Described logic level detecting module 2, itself and wherein connecting pin 100 described in one and described alarm module 3 connect the level position state for detecting described connecting pin and control described alarm module 3 when high level state and send alerting signal.In the present embodiment, described logic level detecting module 2 is baseboard management controller, and any other electronic component can certainly can detecting logic level height for other, does not list one by one at this.
When having screw (not shown) to screw tight in the screw 10 on described circuit board 1, described logic level detecting module 2 can detect described screw 10 and be in low level state, when not screwing tight screw in the screw 10 on described circuit board 1, described logic level detecting module can detect described screw 10 and be in high level state, then can control described alarm module 3 and send alerting signal, notify user's circuit board 1 not locking.
In sum, the various embodiments described above and diagram are only the preferred embodiment of the utility model, but can not with the scope of restriction the utility model enforcement, the equalization change namely generally done according to the utility model claim with modify, all should belong in scope that the utility model patent contains.
Claims (2)
1. a circuit board screw lock safety monitoring system, is characterized in that, comprising: circuit board, logic level detecting module and alarm module;
Described circuit board, which is provided with screw, and described screw has at least two connecting pins, and wherein connecting pin described in connects described logic level detecting module, other connecting pin ground connection remaining; And
Described logic level detecting module, it is connected the level position state for detecting described connecting pin further and controls described alarm module when high level state and sends alerting signal with described alarm module.
2. circuit board screw lock safety monitoring system according to claim 1, is characterized in that, described logic level detecting module is baseboard management controller.
