Further, the microcontroller is externally connected to automatic button, common button and forces button.
Further, it is also associated with status indicator lamp outside the microcontroller.
Further, it is in series with power switch between AC220V input blocks and charhing unit.
In above-mentioned, AC220V input blocks are used for the transformer AC220V output units being connected in elevator control cabinet,
DC110V output units are used for the power supply that declutches for being connected to elevator traction machine, and flat bed detection unit is used for Elevator landing state
Detection, door lock detection unit are used for the detection to the electrical circuit of door lock of elevator.
Contain DC-DC boosting units in flat bed detection unit, can will be that flat bed detection unit supplies after battery booster to DC24V
Electricity；DC110V output units also contain DC-DC units, can export battery booster to DC110V.Therefore, when place unit needs
Supply voltage be higher than cell voltage, then can set accordingly DC-DC boosting come realize boosting power supply.
With reference to shown in Fig. 2, this elevator emergency declutches the DC12V output units of supply unit, door lock detection unit, flat bed inspection
Survey unit, DC110V output units and AC220 input blocks and be provided with Wiring port, correspond to P5, P3, P2 and P1 terminals respectively
Mouthful, wherein the Wiring port of DC110V output units and AC220 input blocks is integrated into P1 Wiring ports.Wherein P5 has 2 to connect
Line end mouth, P3 have 2 Wiring ports, and P2 has 6 Wiring ports；P1 has 4 Wiring ports, and P1 is next to power switch S1.P is
For PIN.
Wherein the available external connection of P1, P2, P3 and P5 Wiring port and function declaration are as shown in table 1 below：
Table 1
This elevator emergency declutch supply unit parameter include but is not limited to configure it is as follows：
Input power：AC220/110V 50/60Hz；
Charging interval：＜ 5 hours；
Battery charge：1.4A(±0.2A)；
Battery charging voltage：1.3VDC(±0.2V)；
Declutch voltage output：Start voltage 110V, maintain power supply 75V；
Power output：400W(MAX)；
The size of product：196*136*122 (units：mm).
This elevator emergency declutches the button of supply unit and being described as follows for status indicator lamp：

A kind of declutch application method of supply unit of this elevator emergency is described as follows：
(there is civil power input) when AC220V inputs have electricity, device is in charged state, now pins any button dress
Put all without output is started, preventing from conflicting with normal power source causes device to damage；
When AC220V is not inputted (i.e. commercial power interruption), while when pressing common button and start button, microcontroller
Door lock break-make is detected by door lock detection unit, starts DC110V when door lock close and exports supply and declutch power coil, declutch
Opening, elevator arrive at a slow speed level position, flat bed signalizing activity, and microcontroller stops output electricity after detecting flat bed signalizing activity
Press, now elevator is parked in level position, and floor where maintenance personal can arrive elevator, which opens the door, discharges trapped personnel；Microcontroller leads to
Door lock detection unit detection door lock break-make is crossed, does not start DC110V outputs when door lock disconnects, it is ensured that safety, and referred to by state
Show that door is in open mode when lamp Door lock with pointing disconnects.
This elevator emergency declutch supply unit door lock detection be to be coupled with P3 two Wiring ports as shown in Figure 4
123 and 127 two signal wire access points, there is between two signal wire access points gate switch and hall door to switch, because peace
Full loop relay KSA and hall door gate relay KSAD Coil resistances are smaller, so the sedan-chair directly between detection 123 and 127
Door switch and hall door switch on-off i.e. difficult accurate detection.Because KSA and kSAD is coil, its inductance value is larger, 123,
Gate switch between 127 connects its inductance value very little with hall door switch for wire, is substantially contrasted with winding inductance quantity, institute
To use, inductance quantity measuring method substantially can accurately detect the gate switch between 123,127 and hall door switches on-off.
Wherein KSA represents safety return circuit relay coil；KSAD represents hall door gate relay coil；SCD represents gate
Switch；SLD represents hall door switch.
Inductance detection principle is described as follows：
P3 two Wiring ports are coupled with to 123 and 127 signal wire access point as shown in Figure 8, then formed
Simple circuit figure as shown in Figure 5, square wave detection signal Uo as shown in Figure 6 is sent by microcontroller, by loop of the door lock shape
Into such as the feedback voltage (Ur) that Fig. 7 and Fig. 8 feeds back and the graph of a relation of time (t).Wherein Fig. 7 is shown, when door lock closes
When, i.e., the feedback signal when gate switch between 123,127 is connected with hall door switch closure；Fig. 8 is shown, when 123,
Feedback signal when gate switch and hall door between 127 switch off, both gaps are obvious.
Therefore, the feedback signal (Ur) at t3 moment can be carved into from the outset by sampling, handled just by internal signal
With accurate judgement or it can differentiate whether loop of the door lock closes.
Therefore, this elevator emergency supply unit that declutches can be switched by detecting inductance value to detect gate switch and hall door
Break-make, because whether door lock closes cause the variable quantity of inductance value larger, inspection more precisely can be contained to door lock of elevator
Survey the detection of the electric loop of gate switch and hall door switch.
Those listed above is a series of to describe illustrating only for possible embodiments of the invention in detail,
They simultaneously are not used to limit the scope of the invention, all equivalent embodiments made without departing from skill spirit of the present invention or change
It should be included in the scope of the protection.
