In order to facilitate understanding above-mentioned technical proposal of the invention, below by way of in specifically used mode to of the invention above-mentioned
Technical solution is described in detail.
Integral type fire resistant doorsets door closer according to the present invention includes: main control unit, communication list as shown in Figure 1:
Member, Charge Management unit and electric discharge releasing unit.Main control unit: having a piece of 8 single-chip microcontrollers, is responsible for the association of the entire circuit of control
Work is adjusted, communication unit passes to the pulse width modulated information of single-chip microcontroller, and single-chip microcontroller is converted into digital signal, analyzes and handles signal
Make respective handling.Charge-discharge circuit charging is controlled, judges charged state.Electric discharge releasing unit is controlled by pin.Communication is single
Member: hardware circuit acquisition pulse width passes to main control unit, i.e., the control of controller and querying command is transmitted to single-chip microcontroller.
And the status information that main control unit returns is sent to master controller.Management of charging and discharging unit: being responsible for charge and discharge movement and execute, and
Charging and discharging state is fed back into main control unit.Electric discharge releasing unit: the electric discharge instruction of main control unit is executed.
As shown in Fig. 2, communication unit part uses pulse width modulation coding scheme, which is simple, is not easy to be disturbed,
Certain power supply capacity is provided between high period.TCIN and VREF is the forward direction of main control unit single-chip microcontroller internal comparator in figure
And reverse input end.Detection signal of the output of comparator as main control unit.Single-chip microcontroller obtains input by way of capture
The pulse width of signal obtains different width by inside filtering processing, pulse width is different represent digital signaling zero or
Signal 1 can be obtained the instruction of alarm host machine.Communicate constant-current circuit can in specific position by main control unit single-chip microcontroller to total
Line sourcing current.The width of sourcing current reflects the state of integral type door closer.So far interactive correspondence can be completed.
The working principle of Charge Management unit are as follows: main control unit controls Q1 triode ON by control I/O port, gives capacitor
Charging.It is excessive and influence bus communication that current-limiting resistance R22 can limit charging current.In addition when GVCC voltage increases or reduces
It will affect the size of charging current, Q4 saturation conduction when charging current is excessive, so that Q3 ends, such charging current
It is constant, until capacitor is fully charged.
Releasing unit discharge as shown in figure 3, terminal J3 connects electromagnetic releaser, it is main after receiving the release signal of host
Whether control unit detection capacitance voltage is full of, and when underfill will not open triode Q2 and metal-oxide-semiconductor Q6, because when capacitor underfill
Electromagnetic release unit can not be driven, and capacitor electric discharge at this time has been completed, capacitor needs, which recharge, to be likely to effectively drive electricity
Magnetic release.When main control unit detects that capacitor is fully charged, release can be just driven.Process is as follows: being first shut off Q1, cuts
Then disconnected two lines bus opens Q2 and Q6 to capacitor charging, instantaneous large-current drives electromagnetic releaser.Integral type fire resistant doorsets are electronic to be closed
Door device tripping, Driven by Hydraulic Cylinder close fire resistant doorsets.Main control unit closes Q2 and Q6 after release, gives capacitor charging, waits release next time
It puts.
Entire circuit is simple and reliable, the operation is stable.It can satisfy system application.
It is released in conclusion the electric releaser of fire resistant doorsets door closer of the present invention only needs capacitor electric discharge that can stablize
It puts, directly by communication, control, management of charging and discharging design on one piece of circuit board, circuit board is installed to inside door closer, is improved
Reliability reduces engineering wiring.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
