According to fire door electric door closer is prevented to integral type, as shown in fig. 1: the method comprises the following steps: the device comprises a main control unit, a communication unit, a charging management unit and a discharging release unit. The main control unit: the system is provided with an 8-bit singlechip, which is responsible for controlling the coordination work of the whole circuit, a communication unit transmits pulse width modulation information to the singlechip, and the singlechip converts the pulse width modulation information into digital signals and analyzes and processes the signals to carry out corresponding processing. And controlling the charging and discharging circuit to charge and judging the charging state. The discharge release unit is controlled by a pin. A communication unit: the hardware circuit collects the pulse width and transmits the pulse width to the main control unit, namely, the control and query commands of the controller are transmitted to the single chip microcomputer. And sending the state information returned by the main control unit to the main controller. A charge and discharge management unit: and the main control unit is responsible for executing the charging and discharging actions and feeding back the charging and discharging state to the main control unit. A discharge release unit: and executing the discharging instruction of the main control unit.
As shown in fig. 2, the communication unit part adopts a pulse width modulation coding scheme, which is simple and not easily interfered, and provides a certain power supply capability during a high level period. TCIN and VREF are the positive and negative input ends of the comparator inside the main control unit singlechip. The output of the comparator is used as a detection signal of the main control unit. The single chip microcomputer obtains the pulse width of an input signal in a capture mode, different widths are obtained through internal filtering processing, the different pulse widths represent a digital signal 0 or a signal 1, and then the instruction of the alarm host can be obtained. The communication constant current circuit can pull current to the bus through the main control unit singlechip at a specific position. The width of the pull current reflects the state of the integrated door closer. Thus, the interactive communication can be completed.
The working principle of the charging management unit is as follows: the main control unit controls the conduction of the Q1 triode through the control IO port to charge the capacitor. The current limiting resistor R22 can limit the charging current from being too large to affect bus communication. In addition, when the GVC voltage is increased or decreased, the magnitude of the charging current is influenced, Q4 is in saturated conduction when the charging current is too large, so that Q3 is cut off, and the charging current can be constant until the capacitor is fully charged.
As shown in fig. 3, the terminal J3 of the discharging releasing unit is connected to the electromagnetic releaser, and after receiving a releasing signal from the host, the main control unit detects whether the capacitor is fully charged, and the transistor Q2 and the MOS transistor Q6 are not turned on when the capacitor is not fully charged, because the electromagnetic releasing mechanism cannot be driven when the capacitor is not fully charged, and at this time, the capacitor is discharged already, and the electromagnetic releaser can be effectively driven only when the capacitor needs to be recharged. The release can only be actuated when the main control unit detects that the capacitor is fully charged. The process is as follows: q1 is turned off first, two buses are cut off to charge the capacitor, then Q2 and Q6 are turned on, and the electromagnetic releaser is driven by the instantaneous large current. The electric door closer of the integrated fireproof door is tripped, and the fireproof door is closed by the driving of the hydraulic cylinder. After releasing, the main control unit turns off the Q2 and the Q6, charges the capacitor and waits for the next releasing.
The whole circuit is simple and reliable, and works stably. Can meet the system application.
To sum up, the utility model discloses prevent fire door electric door closer's electronic releaser only needs the electric capacity discharge can stable release, directly with communication, control, charge-discharge management design on a circuit board, inside the door closer was installed to the circuit board, improved the reliability, reduced the engineering wiring.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
