It gets an electric shock or burns route, therefore will cause certain danger, and prevent the safety measure of accidentally division disconnecting link from mainly having: forbidding grasping
" No switching on, someone's work " Sign Board is hung at the disconnecting link motor power of work or the sky of quiescing is sealed with red insulating tape
Air cock, but the above measure all cannot ensure that air switch is in an off state in practical applications.Field Force still can be with
Air switch is operated by force, closes air switch.
For safety lock there are mainly two types of the type of air switch on existing market: (1) passing through fixed air switch
Rotating operating unit point prevent switch divide-shut brake；(2) forbid division using the lockhole that stainless steel metal stitch blocks air switch
Lock.Although above-mentioned two classes safety lock may be implemented to " lock " on air switch, but still remain some larger disadvantages: (1) locking
After mounting there is no locked function (lock can still be taken off) is really realized, needing in addition to increase padlock can just prevent tool
Others operates.This mode for locking locking, there are big inconveniences in actual management；(2) turned using fixed air switch
A kind of lock of moving axis is easy to fall off, and can not reliably lock switch；(3) if scene needs to lock there are multiple air switches
Situation, then each air switch corresponding one is padlock, and to the key management of padlock, there is also inconveniences.

Specific embodiment
The implementation structure of the utility model is described below in conjunction with attached drawing.
As shown in Figure 1, Figure 2 and Figure 3, a kind of air switch, including air switch ontology 90, microprocessor, communication module,
Relay 8 and power supply；The communication module is connected with microprocessor, and communication module is used to receive background server signal, and will
Signal passes to microprocessor, and the signal of transmitting includes power-off locking signal, power on signal and timing signal etc., the relay
8 are connected through the first amplifying circuit with microprocessor, and relay 8 is set to the main line in air switch circuit diagram 901, are used for
The main line of air switch circuit is opened or closed, since Many times are in running order in the air switch course of work, is
Keep the equipment more energy saving, relay 8 selects normal closing type relay, normal closing type relay it is electric in the case where disconnect, when
When needing to carry out line upkeep or maintenance, enables relay 8 disconnect, air switch can be made to be in power blackout situation, the electricity
Source is that microprocessor, communication module and relay 8 provide electric power.To enable air switch could be used that in the state of power failure,
Power supply is preferable using independent current source, therefore power supply uses battery.
90 outer surface of air switch ontology is equipped with the two dimensional code 93 for terminal device scans, and the two dimensional code 93 includes air
The information of Switch main body 90.
When the Asymmetry information of input air switch and it is more than certain number, and can have effectively reminded air switch
State in power-off locking, air switch further includes loudspeaker, and loudspeaker 94 is through the second amplifying circuit and the microprocessor
It is connected, for use in auditory tone cues.Thus can more efficient prompting air switch be in power-off lock state, air switch also wraps
Signal lamp 92 is included, signal lamp 92 is connected with the microprocessor, and signal lamp 92 selects red LED light, when air switch is in
Power-off lock state lights.
Simultaneously in order to which timing on-off air switch, microprocessor need to have clock circuit, microprocessor is STM32 thus.
The working principle of the utility model is as follows:
A kind of air switch of the utility model, staff or owner are scanned outside air switch using mobile terminal device
Two dimensional code 93 on surface switchs relevant information, such as location information, the equipment controlled and power-off lock to carry out setting air
Fixed password is simultaneously stored on background server, when carrying out electrical equipment or line maintenance, needs to carry out power-off locking, to prevent
Only artificial maloperation combined floodgate makes staff get an electric shock or burn circuit, and staff or owner need to be by the operation handles of air switch
91, which disconnect the two dimensional code 93 for having a power failure and reusing on mobile terminal device scanning air switch outer surface, carrys out input air switch
Associated power-down locking information is simultaneously sent to background server, judges whether its information is correct by background server, if incorrect
It need to re-enter, power-off locking information be sent if correct into the microprocessor STM32 of air switch, STM32 is just further
It obtains normal closing type relay 8 electric, then disconnects air switch main line, synchronous signal lamp 92 lights, and loudspeaker 94 also issues drop
The sound of drop is dripped, to prompt, the dual power-off of air switch at this time, even if the operation handle of someone's maloperation air switch,
Route will not be made to obtain electric, and then staff is made to get an electric shock, when not needing power-off locking, it is disconnected to will pass through mobile terminal device cancellation
Electric lock state only need to make the operation handle of air switch be in closed state, then pass through when needing to start timed on-off of power
Mobile terminal device carries out setting time and has background server to be sent in the micro process of air switch, and microprocessor will be into
Row periodically controls the power on/off of relay 8.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, any variation or simple replacement expected without creative work should all cover the protection model in the utility model
Within enclosing.
