[Objective of the invention]

An object of the present invention is to integrate an automatic door safety device system separated by a time relay, a photo relay, a photo cell, a buzzer, and a bracket, thereby increasing the reliability of the equipment and efficiently utilizing the space.

[Technical Field to which the Invention belongs and Conventional Technology in the Field]

The present invention relates to an integrated automatic door safety device system, and in particular, a time relay which is an automatic door safety device, a buzzer which is an emergency warning device, and a photosensing means for detecting passengers are separately installed, thereby reducing the reliability of the equipment. By integrating them into one assembly, the present invention relates to an integrated automatic door safety device system, characterized in that the reliability of the equipment is increased and the space utilization is increased.

In general, almost all large buses currently manufactured for city buses are designed as automatic doors. Therefore, when using such an automatic door automatically opens and closes using a magnetic cylinder, there is a problem that a safety accident occurs when a passenger gets stuck in the door.

Looking at the operating system including such a safety device, as shown in Figure 1, a predetermined number of passengers on the ceiling and the inner side panel of the vehicle is installed, the passenger button (1) indicating the section to get off is installed, the passenger button ( When 1) is turned on, a buzzer (2) is provided to provide a constant sound through the signal relay, and the stop signal display lamp (3) is displayed so that the passenger button (1) is pushed and the driver can recognize it. A rear door open indicator lamp (4) indicating whether the rear door is open and a safety indicator lamp (5) indicating whether a safety accident has occurred around the door are installed on the instrument panel. The rear entrance search lamp 6 and the search lamp operation switch 7 which provide illumination for getting off are installed, and the operation of the rear door operation switch 8 and the rear door operation switch 8 is performed. And the rear side door along the working cylinder 9 to the cake flow to the left and right door installation, and the external operation switch 10 is installed to help a driver operates the door cylinder when operating the door from the outside.

On the other hand, as a safety device installed for the safety of the door device to operate the door cylinder in accordance with the operation of the door operation switch and the time relay 11 to function as a processor for controlling the safety equipment, and the time relay when the door cylinder operation The light emitting elements 12-1 and 12-2 and the light receiving elements 13-1 and 13-2 are detected so that the distance between the doors can be detected by the signal output from 11 to check an object between the door gaps. It comprises a photo relay 14 for controlling, and a buzzer 15 for outputting a warning when an emergency occurs.

The door device made as described above is a stop on the instrument panel so that the buzzer 2 sounds while the light bulb inside all the passenger buttons is turned on when the passenger presses the passenger button 1 first. The signal display lamp 3 lights up.

Then, the driver operates the rear operation switch 8 at the stop to stop and flows the rear door cylinder 10, thereby opening the door and inducing the passenger to get off.

At this time, the rear door open indicator lamp 5 is turned on the instrument panel of the driver's seat, and by operating the rear search lamp switch 7 at night, the passengers who get off can safely get off by turning on the lamp 6.

On the other hand, the safety device installed between the doors for the safety of the passengers by controlling the door cylinder 9 and the photo relay 14, and the alarm sound buzzer 15 by the time relay 11 as a processor with an appropriate time difference The action is made.

That is, when the door operation switch 8 is turned on, the time relay 11 sends a signal to the door cylinder 9 to activate a photo relay to check whether an object is present between the door gaps when the door is closed. Is present between the door gaps, the door buzzer 15 is operated without operating the door cylinder 9, and the driver repeats the action of informing that the driver is not finished.

[Technical Challenges to Invent]

However, since the above devices are separately installed and instructed to control the time relay, the reliability of the device is low and space utilization is not desired.

Therefore, the present invention is designed to increase space efficiency by integrating these devices into one assembly, inserting them into a case, and mounting a transceiver in one assembly.

Composition and Action of the Invention

As a means for achieving the above object,

The present invention integrates a buzzer, a photosensing means and a relay means in one assembly, and forms a pair of two sets of transmitters and receivers on both sides and a buzzer in the center.

Hereinafter, described in detail with reference to the drawings.

2 is a front view of the assembly structure of the present invention, integrating the buzzer 21, the photo-sensing means 22-1, 22-2, 23-1, 23-2 and the relay means in one assembly 20; The two sets of transmitters and receivers in pairs 22-1, 23-1 and 22-2 and 23-2 are installed at both sides, and the buzzer 21 is installed at the center.

3 shows an example in which the apparatus through the above is applied to a circuit configuration.

On the other hand, as shown in Fig. 4, the transceiver includes an oscillator 30 for generating a fundamental wavelength, a transmission output unit 31 for outputting a transmission wave by breaking a signal of the oscillator 30 in a predetermined unit, and the transmission. Output amplifiers 32-1 and 32-2 for amplifying the output wave, and the transmission waves amplified above are transmitted through the photo transistors 33-1 and 33-2 and the lenses 34-1 and 34-2. The light emitting units 35-1 and 35-2 to emit to the outside, and the beams 36-1 and 36-2 reflected by the light emitted from the light emitting units 35-1 and 35-2 and the light receiving element. Set the light receiving units 38-1 and 38-2 to receive through 37-1 and 37-2, the light receiving signal amplifiers 39-1 and 39-2 to amplify the received wavelengths, and the necessary wavelengths. The wavelength setting unit 40-1, 40-2, the comparison unit 41 for outputting data for calculating distance data by comparing the first transmission signal and the reception signal, and the output unit from the comparison unit 41; Differences exist when comparing distance data with reference distance When the door switch 44 operating in closed door state signal is input, and outputs an alarm sound through a buzzer 43, and is composed of a control unit 42 to stop the operation of the door cylinder 45.

The portion blocked by the dotted line is a pair of light-receiving units, and in the present invention, two sets of light-receiving units are positioned.

The present invention configured as described above operates the door cylinder 45 when the first door open signal is received, and then operates the distance detection sensor composed of the transceiver.

The oscillator 30 continuously generates a constant waveform and the transmission output section 31 transmits a beam having a required amount of wavelength. Subsequently, the amplification units 32-1 and 32-2 amplify the wavelengths of the beams, and the amplified beams are moved to the outside through the lenses 34-1 and 34-2 in the light emitting units 35-1 and 35-2. Fire.

The comparison unit 41 compares the first signal with the received signal. When the basic data for calculating the distance data is generated and sent to the controller 42, the controller 42 converts the distance data into distance data and compares the distance with the programmed reference distance.

Since the distance sensor is programmed in advance of the door and the closing point of the door, if you want to close the door in the presence of a person or object, the door cylinder 45 is preferentially controlled to prevent the door from closing and at the same time the buzzer ( 43) to warn that getting off is not over yet.

Therefore, the present invention can operate the sensor and the buzzer with the simple equipment described above, thereby increasing the reliability of the equipment and utilizing the space appropriately.
