Description of the invention: [Technical field of the invention] The present invention relates to a door closing monitoring device and method with a memory function, particularly a monitoring device that is installed around a door to carry out a fairy and can avoid a passenger with a door jam. And methods. [Prior Art] In the mass transit vehicle, the accidental pinch of the passenger's door is accidentally pinched by the bus and the bus is private. The front door has two front and rear doors. The door is opened and closed by the driver. The control 'Shaw prevents the person or object from being closed when the door is closed. The driver must observe the presence or absence of a person or object in the n-zone of the vehicle through the rear view mirror or the rear mirror on the outside of the vehicle before closing the door. In the passengers: when the passengers get off, it is very likely that the driver’s line of sight is obscured, and the person who mistakenly closes the door is judged by the gossip, especially at the back door. At this time, if the passenger is still on and off. When the soil was squatted and stalked, it was caught in the door of the car. It was like this kind of early sin to judge the door closed. L No towel clips the accident of the people - the solution is to install the camera at the adjacent door, and drive: small monitor (M°nit °., but considering the surveillance, it is possible for the camera to shoot The lady at the door of the car is shining, so this kind of k. It is not widely used. Another solution is to install on the door, and to measure the benefits (similar to the elevator), if there is a person or when the door is closed When the object is clamped, the door will open automatically. 'But when it is a backpack with a bag, L, scarf, clothes and other flexible objects, the above sensor may not be detected, so oh,... For example, passengers may be dragged down after starting the vehicle when they get off. The third solution is to install an infrared sensor above the door. When there is someone at the door, Prompt to drive 5 sound waves of p 4, μ, ^ Do not close the door, but the Tian bus is very late, infrared or ultrasonic sensor - people or objects near the door, resulting in system false alarms. T - detected [ Summary of the invention In view of the fact that the existing device for detecting the closing of the door still has a system invention, it is intended to provide a door closing method, a point method, and a memory function. By pre-storing a net-shaped suture outside the door, it is judged whether there is still The person stays on the outside of the door: Test: The second mistake of the vehicle is closed. ^There is no way to reduce the amount of the memory. The method of memory of the present invention includes: · The door is closed and the vehicle is closed. When the first signal is emitted, the environment state outside the door is closed; and the second pre-test signal is transmitted when the door is to be closed. 4 There is no obstacle underneath, and 'the door pivot obstacle exists to allow one. The tamper is judged to be closed; + the door is closed, if there is an obstacle, the door is prohibited from being fired when the door is closed __ external environment state; "Detective signal" to detect and record the door is a pair - the Detective The measured signal is measured outside the door as measured by the s-second detection signal.] The situation on the side of the side and the state of the outside of the door. If the two are obviously not the same, the door is closed. The other is the purpose of providing - the door is closed, the device contains... The first ultrasonic sensor with 4 functions is installed on the top of the door frame of the door, and the top frame of the negative door is measured. Below, the first-ultrasonic sensor is responsible for detecting the adjacent area outside the door; - the microprocessor has an internal memory built in; the nickname transceiver unit is connected to the microprocessor and controls the aforementioned The first super-detector and the second ultrasonic sensor emit a supersonic detection signal and receive the echo signal thereof; the door wave is amplified early, and is connected to the signal transceiving unit and the microprocessor to amplify the signal. The echo signal received by the unit, the amplified back '^ number is transmitted to the micro-segment for processing; the detectable and dependent-door switch judgment and control circuit is connected to the aforementioned microprocessor threshold or not Turning off the 'output-corresponding signal to the microprocessor (1) describes the control of the U processor to determine the opening/closing action of the door; wherein the first-ultrasonic sensor is controlled by the microprocessor, in the vehicle::1 Kai:: Launching Detecting signals to detect and record the outer door of the storage door. 'The first: the ultrasonic sensor is to close the door _ the signal to detect the presence of a person directly under the top of the door frame: in; the door is closed At the time, the first-ultrasonic system emits a third integrated measurement signal, which is angrily tested. The external environment of the door has been recorded, and the microprocessor compares the aforementioned first
