specific Embodiment approach 1

[0006] Specific implementation mode one: the following combination figure 1 This embodiment will be specifically described. This embodiment consists of a window 8, a gas detection sensor 1, a measuring circuit 2, an FPGA circuit board 3, a stepper motor 4, a mechanical window opening mechanism 5, and a pressure sensor 7. The signal output end of the gas detection sensor 1 is connected to the measurement The signal input end of the circuit 2, the signal output end of the measurement circuit 2 are connected to the detection signal input end of the FPGA circuit board 3, the stepping pulse signal output end of the FPGA circuit board 3 is connected to the power input end of the stepping motor 4, and the stepping motor 4 The output shaft of the motor drives the opening and closing sash 6 on the window 8 through the mechanical window opening mechanism 5, and a No. 1 pressure sensor 7 is arranged at the opening and closing position corresponding to the opening and closing sash 6, and ...

specific Embodiment approach 2

[0007] Specific implementation mode two: the following combination figure 1 This embodiment will be specifically described. The difference between this embodiment and Embodiment 1 is: it also includes No. 2 pressure sensor 9, No. 2 pressure sensor 9 is arranged on the closing cut-off position of opening and closing sash 6, and the signal output end of No. 2 pressure sensor 9 is connected to FPGA circuit The other signal input terminal of the board 3 is used to output the control signal for stopping the stepper motor 4 . So arranged, when the FPGA circuit board 3 outputs the reverse stepping pulse to the stepping motor 4 to close the opening and closing sash 6, the No. 2 pressure sensor 9 can stop the stepping motor 4 when the opening and closing sash 6 is closed.

specific Embodiment approach 3

[0008] Specific implementation mode three: the following combination figure 2 This embodiment will be specifically described. The difference between this embodiment and Embodiment 1 is: the window 8 is a shutter, and the mechanical window opening mechanism 5 is composed of a gear pair 10, a lead screw 11, a lead screw nut 12, a first connecting rod 13, and a second connecting rod 14. Composed of No. 3 connecting rod 15, the input shaft of the gear pair 10 is connected to the output shaft of the stepping motor 4, the output shaft of the gear pair 10 is connected to one end of the lead screw 11, and the lead screw nut 12 is screwed on the lead screw 11. One end of connecting rod 13 is hinged on the outer surface of lead screw nut 12, and the other end of No. 1 connecting rod 13 is hinged with an end of No. 2 connecting rod 14 and an end of No. 3 connecting rod 15. No. 1 connecting rod 13, No. 2 The connecting rod 14 and the third connecting rod 15 are distributed into a "tride...

Abstract

The invention provides an anti-poison intelligent window, relates to a window capable of automatically opening when coal gas is in a room, and overcomes the defect that the prior gas detection device only can detect dangers, but cannot eliminate the dangers. The anti-poison intelligent window comprises a window body, a gas detection sensor, a measuring circuit, an FPGA circuit board, a stepping motor, a mechanical window opening mechanism and a No.1 pressure sensor; a signal output end of the gas detection sensor is connected with a signal input end of the measuring circuit; a signal output end of the measuring circuit is connected with a signal detection input end of the FPGA circuit board; a step-by-step impulse signal output end of the FPGA circuit board is connected with a power supply input end of the stepping motor; a motor output shaft of the stepping motor drives an opening and closing sash on the window body through the mechanical window opening mechanism; and an open stopping position corresponding to the opening and closing sash is provided with the No.1 pressure sensor, and a signal output end of the No.1 pressure sensor is connected with a signal input end of the FPGA circuit board to output a control signal for stopping the stepping motor.

Description

technical field [0001] The invention relates to a window which can be opened automatically when there is gas in the room. Background technique [0002] Now gas poisoning has become a big killer that threatens people's lives. Every year, many people cause gas poisoning accidents because of heating in winter. Especially in some small and medium-sized cities where electric heating equipment is not widely used, gas poisoning often occurs. Secondly, the leakage of household gas stoves and gas cylinders is also an important cause of gas poisoning. There are also gas poisoning incidents caused by some water heaters for bathing that have not passed the qualified certification. The device that detects gas automatically is arranged in the family that has at present, but does not have the window that can open automatically. When the gas concentration reaches danger, if parents go out to work and leave their children at home, the children will not know how to deal with this situation....
