[Industrial applications]

 The present invention involves an automatic door control system, which receives signals from a detector by a central control system, then issues two sets of signals, one of which is a direct rotation control.・ Sending to the circuit and the motor drive circuit, commanding the start of the motor and operating clockwise and counterclockwise, the other set of signals is an analog signal after passing through the D / A conversion circuit. It is also possible to compare the voltage of the generator at the end of the motor in the comparator circuit and send the result of the comparison to the phase control circuit, thereby controlling the shifting of the motor.

[Prior art]

 As people construct houses and become a place to block the wind or avoid the rain, and the gate fan becomes the key to control the entrance and exit of the room, it constantly evolves and changes, and it automatically changes from the artificial opening and closing method. Advances have been made to auto doors that open and close by reconnaissance and guessing.The auto door that is often used there is that it uses a sensor installed above the contact point of the two gate fan to detect people and people. It guesses the passage of an object and automatically activates the motor to open the double gate fan to the left end, and when a person or object passes, it starts the motor again and opens and closes automatically, but Since these operating methods have a relatively large momentum after the motor is started, it cannot be stopped immediately after the operation is finished, and when it hits or closes the walls on both sides, it is a double gate fan. To each other The collision, easy to damage the Mon'ogi generates a big sound.

After that, a trader developed a two-stage method by installing a touch switch at an appropriate point near the end of the guideway of the two-gate fan and touching the door while opening or closing the gate fan.・ If you touch the switch, the momentum of the gate fan does not increase even if the motor fails, and you can start the motor with a relatively small voltage to obtain a relatively small horsepower, and delay the speed at which the gate fan moves. The double gate fan is designed to open just right at the end of the guideway, or to stop exactly in the center when closing.

[Problems to be solved by the device]

 However, these methods of operation greatly reduce the useful life of the motor by starting the motor when opening or closing and causing two power outages: and when installing these auto doors. Since the areas to be opened are not all the same, the opening width, speed and time are bothersome, and the control system is installed at the top of the slot, so that the operator constantly moves up. It is very inconvenient because it adjusts the auto door by going up and down and then down: if a foreign object is suddenly caught between the two gates, it will continue to open and close. Only after foreign matter is removed does normal operation resume, and not only is power wasted, but the service life of the motor is further shortened.

The applicant is a supplier of control systems for auto doors, and in light of the above-mentioned faulty measures, he actively thinks of ways to improve, and after constant design and testing, finally devised the present invention. It has been acquired.

[Means for Solving the Problems]

 The present invention provides an improved auto door control system, which receives the condition signal mainly coming from the detector by the central control system and then emits two sets of signals. One set of signals controls the start of the motor and the direction of clockwise and counterclockwise rotation, and the other set of signals goes through the conversion of the analog signal before the power generation at the end of the motor in the comparator circuit. A comparison is made with the voltage value coming from the machine, and the result of this comparison goes through a phase control circuit, which controls the shifting of the motor, and the generator of the motor also issues another set of signals to the counter.・ The number of rotations of the motor given to the circuit is controlled by the central processing system. One of the doors of the auto door is to let the driver know if the position of the auto door and the moving speed at that time are in agreement with each other. Ensures movement at one speed at a position, starts the motor immediately after opening or closing the auto door, and then completes the operation by the deceleration method in sequence to start multiple orders. Therefore, the main purpose of the present invention is not to affect the life of the motor and at the same time not waste the power supply.

The present invention provides an improved auto door control system, which connects the control circuit to the outside of the present invention and automatically controls the personnel installing the auto door by the line control method. There is no need to directly adjust the width and speed of opening and closing of the door, and the time of stagnation, and it is not necessary to spend time and force to reach the top of the gate fan, and the installation personnel should be professional or experienced. The next object of the present invention is not only to be abundant but also to be freely attached.

The other objects and advantages of the present invention will be more clearly described with reference to the accompanying drawings.

【Example】

 The special structure operated in order to achieve the above-mentioned designing purpose of the present invention in combination with the circuit of the present invention, its technical means and characteristics will be described in detail as follows. Referring to FIGS. 1 and 2, the present invention is a power supply circuit 1, a central control system 2, a rotation control circuit 3, a motor drive circuit 4, a conversion circuit 5, and an amplifier refinement. Includes the following: Circuit Circuit 6, Phase Control Circuit 7, Comparator Circuit 8, Counter Circuit 9, Outside Conversion Circuit A, Memory Circuit B, Connector C, etc.

The power supply circuit 1 transforms and rectifies after passing through the voltage transformation and rectification to become the voltage applied to the present invention, and the detector A2 is connected to the outside of the outside conversion circuit A, When an object or an object passes through the auto door, the detector A2 sends the signal to the central control system 2 for processing, and the voltage is too high to burn down the central control system 2. In order to prevent this, first the buffer A1 is passed and then the voltage that is too high is stopped, and then two sets of signals are issued from the system 2, one of which is set to the rotation control circuit 3 and the motor drive. Send it directly to Serkit 4 and make full use of the motor 41 to start it. It controls the left or right turn to open or close the auto door. It sends another set of signals to the D / A conversion circuit 5 and then converts it to an analog signal, The signal is further sent to the comparator circuit 8 through the amplifying function of the amplifying circuit 6 and compared with the voltage value of the generator at the end of the motor 41. If the voltage value of the generator is high, For example, sending a set of signals to the phase control circuit 7 to control the rotation control circuit 3 will immediately modify the deceleration of the motor 41, lowering its voltage value and vice versa. This also means that the generator of the motor 41 also sends a set of signals to the counter circuit 9 at the same time. From 9 the number of rotations of the motor 41 is converted into a signal and sent back to the central control system 2, and this signal displays the current position of the auto door, so naturally all the speeds and rotations of the motor 41 The speed becomes a set of experience values after the operator has calibrated and adjusted the interrelationship between the moving speed and the position of the auto door in advance, and the speed is stored in the memory circuit B, and the central circuit is used at any time. Provided to the control system 2, there is a moving speed corresponding to each other at one position at that time when the auto door turns clockwise or counterclockwise, and there is a signal sent back to the above position in the memory circuit B. If there is a discrepancy, as compared to experience, rotate control search again. The speed of the motor 41 is adjusted via Step 3, and the speed of the motor 41 and the number of rotations are continuously compared, and the opening and closing of the motor 41 once during the operation of the automatic door is sequentially reduced ( It does not affect the service life of the motor by accelerating, making multiple opening and closing operations, and smoothly opening and closing the auto door.

Further, an operation key board is connected to the outside of the connector C of the present invention to directly calibrate the opening and closing speed and width of the auto door to the operator who installs the auto door, and the stagnation time. It can be adjusted and these digitals can be input and stored by the memory circuit B for very convenient use.

If an object is stagnant between the two fans, first, one data is input into the memory circuit B, and the automatic doors of the two fans cannot be completely closed several times in a row. If it does, it is necessary to automatically stop the motor rotation and prevent unreasonable waste of power, activate the switch again and restore all functions, and connect the power to the memory circuit B. There is also no.
