In order to realize the purpose, the technical scheme of the utility model is that:
the utility model provides an automatic blocking device, includes that the password sets up the panel, blocks logic control chip, infrared switch ware, rotatory stopper, infrared switch ware inside infrared emission head, switching value receiving head and the window inductive head included, rotatory stopper inside step motor, rotatory stopper and the motor driver chip included, step motor be connected with the motor driver chip, block logic control chip and set up panel, switching value receiving head and motor driver chip with the password respectively and be connected.
In the automatic blocking device, the blocking logic control chip adopts a micro MCU chip STM8L152C8T 6.
In the automatic blocking device, the motor driving chip adopts the micro stepping motor driving chip TMC 2130-TA.
The utility model discloses a stopper is opened immediately after the monitoring window is opened to prevent that children from opening the dangerous condition that the window caused.
Drawings
Fig. 1 is a structure diagram of the installation of the automatic blocking device of the present invention.
Fig. 2 is a schematic circuit diagram of the automatic blocking device of the present invention.
Detailed Description
The embodiments of the present invention will be further explained with reference to the drawings.
Referring to fig. 1 and 2, an automatic blocking device includes a password setting panel 1, a blocking logic control chip 2, an infrared switch 3, and a rotary blocker 4, wherein the infrared switch 3 includes an infrared emitting head 5, a switching value receiving head 6, and a window sensing head 7, the rotary blocker 4 includes a stepping motor 8, a rotary blocking head 9, and a motor driving chip 10, the stepping motor 8 is connected to the motor driving chip 10, and the blocking logic control chip 2 is respectively connected to the password setting panel 1, the switching value receiving head 6, and the motor driving chip 10.
Preferably, the blocking logic control chip 2 adopts a micro MCU chip STM8L152C8T 6.
Preferably, the motor driving chip 10 adopts a micro stepping motor driving chip TMC 2130-TA. The motor driving chip 10 is connected with the blocking logic control chip 2 through an SPI digital interface, and the blocking logic control chip 2 can control the rotating direction and the rotating angle of the stepping motor 8 driven by the motor driving chip 10 through a digital SPI command.
The password setting panel 1 is provided with a nixie tube 11 and a film key 12, a starting password is set during equipment initialization, when a password value input by the film key 12 and received by the logic control chip 2 through an IO interface is consistent with an initial password stored inside, the key input function of the film key 12 is started by the logic control chip 2, and the nixie tube 11 is used for synchronously displaying setting parameters and setting state data.
The infrared emission head 5 and the switching value receiving head 6 are arranged on two sides of the inner wall of the infrared switch device 3, the switching value receiving head 6 continuously receives infrared signals emitted by the infrared emission head 5, so that low level signals are output to an IO interface of the blocking logic control chip 2, the window induction head 7 is installed on the movable window 13, when the window is closed, the window induction head 7 is located between the infrared emission head 5 and the switching value receiving head 6, at the moment, the infrared signals are blocked by the window induction head 7, so that the switching value receiving head 6 cannot receive the infrared signals and output high level signals, and when the blocking logic control chip 2 receives the high level signals through the IO interface, the window is indicated to be in a closed state; and if the window is opened by personnel, the window inductive head 7 can move out between the infrared emission head 5 and the switching value receiving head 6, so that the switching value receiving head 6 receives the infrared signal and outputs a low level signal, and at the moment, when the blocking logic control chip 2 receives the low level signal through the IO interface, the window is in an open state.
When an adult needs to start the protection function of the whole system, after a password is input through the membrane key 12, the key function of the membrane key 12 is started, and the protection function of the whole system is started through a system start key on the membrane key 12, after the blocking logic control chip 2 receives a start command, the output state of the switching value receiving head 6 is collected in real time through an IO interface, when the blocking logic control chip 2 detects a high level signal through the IO interface, it indicates that the current window is in a closed state, so that the blocking logic control chip 2 does not perform any operation, and if the blocking logic control chip 2 detects a low level signal through the IO interface, it indicates that the window is opened, so that the blocking logic control chip 2 sends a command of rotating counterclockwise by 90 degrees to the motor driving chip 10 through the SPI interface, so as to drive the stepping motor 8 to rotate counterclockwise by 90 degrees, because the rotation blocking head 9 is fixed on the rotating shaft of the stepping motor 8, when the stepping motor 8 rotates 90 degrees anticlockwise, the rotation blocking head 9 can be extended out to be blocked in front of the moving window 13, so that the moving window 13 is prevented from being further opened, and a dangerous state that a child passes through the window after the moving window 13 is opened is effectively prevented; and after the moving window 13 is closed, when the blocking logic control chip 2 detects a high level signal through the IO interface, it indicates that the moving window 13 is closed, and then the blocking logic control chip 2 sends a command of rotating clockwise by 90 degrees to the motor driving chip 10 through the SPI interface, so as to drive the stepping motor 8 to rotate clockwise by 90 degrees, and rotate the rotation blocking head 9 back into the rotation blocker 4, thereby not affecting the subsequent use of the moving window 13 by adults.
And if the adult does not need to start the whole protection function, after the password is input through the film key 12, the key function of the film key 12 is started, and the protection function of the whole system is closed through the system closing key on the film key 12, so that the whole window recovers the opening and closing functions of the conventional window, and the normal use of the adult is not influenced.
For the convenience of installation, all electronic components of the utility model all adopt the battery to supply power.
The utility model discloses a stopper is opened immediately after the monitoring window is opened to prevent that children from opening the dangerous condition that the window caused.
