Abstract
The present invention discloses a power distribution cabinet for preventing a door from being misclosed. A door is provided with an electronic lock, a first Hall inductor is arranged at the inner side of the door, and the second Hall inductor is arranged at the outer side of the door; the two Hall sensors are connected with a counter with an initial numeration value of zero, and the counter is connected with a single-chip microcomputer; the second Hall sensor is connected with the single-chip microcomputer, the single-chip microcomputer is connected with a controller, and the controller is connected with the electronic lock; a magnet is arranged on the operator's working clothes; when the second Hall sensor feels the magnet, and the single-chip microcomputer is configured to control the opening of the electronic lock through the controller; when the first Hall sensor feels the magnet after the second Hall sensor feels the magnet, the counter adds one numeration and transmit the numeration information to the single-chip microcomputer; when the second Hall sensor feels the magnet after the first Hall sensor feels the magnet, the counter reduces one numeration; and when the numeration of the counter is zero, the electronic lock is locked. The power distribution cabinet for preventing a door from being misclosed is able to effectively avoid the condition that the power distribution cabinet is closed when operators are in the cabinet.
Description
Technical field
The present invention relates to electrical facility technical field, especially relate to a kind of power distribution cabinet preventing and closing the door by mistake.
Background technology
Integrated the electronic devices and components extremely many for number in power distribution cabinet, especially for comparatively large-scale power distribution cabinet, it generally requires several operator when assembling and maintenance and within it carries out.So, very easily occur certain or multiple operator not yet in this power distribution cabinet out, and the external staff's locking door of this power distribution cabinet (this door often cannot be opened in inside), after closing even at the door of power distribution cabinet, external staff is its power transmission, then causes security incident.
Summary of the invention
It is an object of the invention to provide a kind of power distribution cabinet preventing and closing the door by mistake, it has can be prevented effectively from power distribution cabinet situation about closing when there is operator, then safer feature.
The technical solution adopted in the present invention is: prevent the power distribution cabinet by mistake closed the door, and during for preventing from having in power distribution cabinet operator, external staff closes the door of this power distribution cabinet, and wherein, this door is furnished with electronic lock,
The inner side being positioned at door on described power distribution cabinet is provided with the first hall sensor, outside is provided with the second hall sensor, this equal signal of first, second hall sensor is connected to an initial enumerator that counter value is zero, this counter signals is connected to a single-chip microcomputer, and this second hall sensor signal is connected to this single-chip microcomputer, simultaneously, this single-chip microcomputer signal is connected to a controller, and this controller signals is connected to this electronic lock；
Described operator is installed with working clothing, and this working clothing is provided with Magnet；And
When this second hall sensor experiences this Magnet, this second hall sensor signal is transferred to this single-chip microcomputer, and this single-chip microcomputer controls this electronic lock by this controller and opens；
When this first hall sensor experiences this Magnet after this second hall sensor, this enumerator increases a numeration and this count information is transferred to this single-chip microcomputer；
When this second hall sensor senses this Magnet after this first hall sensor, this enumerator reduces a numeration；
When the numeration of this enumerator is zero, this electronic lock locking.
Described single-chip microcomputer is connected to the display of the counter value for showing this enumerator.
Advantage for present invention is: can be prevented effectively from power distribution cabinet situation about closing when there is operator, then safer.The electronic lock of the door of the power distribution cabinet preventing from by mistake closing the door of the present invention only has can locking when the count value of enumerator is zero, and this enumerator counts according to the order of 2 hall sensors (i.e. the first hall sensor and the second hall sensor) induced magnet, thus when still having operator in power distribution cabinet, the count value of this enumerator is necessarily not zero.So, effectively prevent this phenomenon of false-lock.

Detailed description of the invention
Embodiment, as shown in Figure 1: prevent the power distribution cabinet by mistake closed the door, during for preventing from having in power distribution cabinet operator, external staff closes the door 10 of this power distribution cabinet, and this door 10 is furnished with electronic lock 20.That is, only when this electronic lock 20 receives correct lock information, this door 10 locking or can be blocked.More specifically, the inner side this power distribution cabinet being positioned at door 10 is provided with the first hall sensor 31, outside is provided with the second hall sensor 32.This first hall sensor 31 and this equal signal of the second hall sensor 32 are connected to an initial enumerator that counter value is zero 40.This enumerator 40 signal is connected to a single-chip microcomputer 50, and this second hall sensor 32 signal is connected to this single-chip microcomputer 50.That is, the count value of this enumerator 40 can be delivered to this single-chip microcomputer 50, the induction information of this second hall sensor 32 also can be transferred to this single-chip microcomputer 50.Meanwhile, this single-chip microcomputer 50 signal is connected to a controller 60, and this controller 60 signal is connected to this electronic lock 20.That is, the locking of this electronic lock 20 is subject to the control of this controller 60.
Meanwhile, the operator entering this power distribution cabinet is all installed with working clothing, and this working clothing is provided with Magnet 70.When this second hall sensor 32 experiences this Magnet 70, this second hall sensor 32 signal is transferred to this single-chip microcomputer 50, and this single-chip microcomputer 50 controls this electronic lock 20 by this controller 60 and opens.That is, the operator not dressing relevant work clothes cannot be introduced in this power distribution cabinet.
And, when this first hall sensor 31 experiences this Magnet 70 after this second hall sensor 32, this enumerator 40 increases a numeration and this count information is transferred to this single-chip microcomputer 50.That is, when operator enters power distribution cabinet from outside to inside, this enumerator 40 increases a numeration.When this second hall sensor 32 senses this Magnet 70 after this first hall sensor 31, this enumerator 40 reduces a numeration.That is, when operator is from the inside to the outside from time in this power distribution cabinet out, this enumerator 40 reduces a numeration.When the numeration of this enumerator 40 is zero, this electronic lock 20 locking.That is, only when in power distribution cabinet entirely without operator, this electronic lock 20 can locking.
Optimizing, this single-chip microcomputer 50 is connected to the display 80 of the counter value for showing this enumerator 40.So, it is simple to user gets information about the number in power distribution cabinet.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the present invention and accompanying drawing content to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all in like manner include in the scope of patent protection of the present invention.
