Description

Setting switch function device and setting method of electric shutter

The present invention relates to a setting switch function device and a setting method of an electric shutter, and installs a push switch recognition means to perform a setting switch function by a combination of existing push switches, and when a press is recognized by a combination of push switches, Recognizing this setting function, the relay unit can be operated.

In general, the electric shutter is to open and close the shutter using the electric motor. 1 and 2, the lower end of the slat 1 of the shutter function forms a reinforcing seat plate 2, the slat 1 is wound around the shaft 3, and the shaft 3 The bottom of the) is finished with an auxiliary plate (4) that allows only the access of the slat (1). The circumference of the shaft 3 is closed by the shutter box 5. The shaft 3 is powered from the motor 6, the clutch 6 is provided with a clutch lever 12-5 for driving a limit switch for limiting the rise and the fall on the shaft of the motor 6, and the pressure is provided at any location on the wall. The switch 7 drives the relay unit 13 to control the raising, lowering and stopping operation of the motor 6. The slat 1 rises and falls along the guide rail 8 and has a constant width 9 and a height 10. The shaft 3 and the slat 1 allow the slat 1 to be safely wound or unrolled through the anti-bending roller 11. Such a general electric shutter is set by pressing the push switch (7) at the time of installation and operating the clutch lever (12-5) at the maximum ascending position to set the lift limit switch (12-1) to off state from the normal on state. , Then press the stop switch of the push switch (7), and then press the down switch to lower the slats (1), and operate the clutch lever (12-5) again at that position to lower the limit switch (12) described in FIG. -2) is used by operating setting from normal on state to off state. As an example of the connection diagram of the motor operation, as shown in FIG. 3, a stop switch 7-3 which downloads an input AC power to a predetermined level and switches one end thereof to a normal on state, and a rising and falling switch 7-1 of a normal off state. And 7-2) the push switch 7; Relay part consisting of relay coil L1 and contacts 13-1, 13-2 and 13-3, relay coil L2 and contacts 13-4, 13-5, and 13-6 ( 13); A motor (6) which rotates according to the selection of the contacts (13-3, 13-6) and has a drive gear (6-2) on the shaft (6-1); A limit switch having a driven gear 12-3 interlocked with the drive gear 6-2, and a gear mechanism such as a speedometer is incorporated in the case 12-4, and operated by operation of the clutch lever 12-5. 12-1) (12-2) is made up of the limiter portion 12 is limited to rise and fall. The contacts 13-2, 13-5, 13-3, and 13-6 are normally off, and the contacts 13-4, 13-1 and the switches 7-3, 12-1 and 12-2. Is normal. This causes the coil L1 to be magnetized when the rising switch 7-1 is turned on to turn on the contacts 13-2 and 13-3, turn off the contact 13-1, and the limit switch 12-1. Since the state is normally on, the state continues and the ascending rotation of the motor 6 through the contact 13-3 starts. In this case, the rising switch 7-1 is pressed once and returns to off, but the contact 13-2 is turned on so that the state can be maintained. In this case, even if the lowering switch 7-2 is pressed immediately by mistake, the contact 13-1 is turned off, and the coil L2 cannot be magnetized and the lowering function cannot be performed. In this state, when it rises to a setting level, a user or an installer operates the clutch lever 12-5, and turns off the limit switch 12-1, and interrupts a synergy action. In this way, once the limit switch 12-1 is set, it is turned off at that position, so that the rising limit position can be continuously set. On the other hand, in the case of setting the lowering, when the stop switch 7-3 is pressed after the rising setting, the rising relay coil L1 is turned off to achieve a standby state, and then when the lowering switch 7-2 is pressed, the coil L2 is turned off. The magnetization causes the contacts 13-5 and 13-6 to be turned on, and the contacts 13-4 are turned off to rotate the motor 6 in the downward direction. Similarly, when the limit switch 12-2 is turned off by operating the clutch lever 12-5 at the lower limit position, the lowering stops. The limiter 12 has a mechanism in which the gear mechanism is built in the case 12-4 and operated by the clutch lever 12-5, such that the gear mechanism is easily worn and the durability is degraded. have. In addition, in order to operate the clutch lever there is a problem that must be raised to the limiter position at the initial setting.

An object of the present invention is to enable the user to set without using an external change by using a conventional push switch, so that the microcomputer can recognize it as a setting switch function when operating in combination.

To this end, the present invention recognizes the setting position with a semiconductor sensor so that the operation of the limiter portion fitted to the shaft of the electric motor can be performed electronically, and the setting function adds a push switch recognition means for recognizing the operation state of the existing push switch. In the combination input, the microcomputer recognizes this as a setting position indication command and controls the relay unit according to the command.

That is, according to the present invention, the semiconductor sensor unit which interlocks with the drive shaft of the driving motor of the electric shutter and detects the rotational speed of the motor, presses the operation state of the push switch to set the rising and falling points of the shutter according to the rotation of the motor. It comprises a switch recognition means, and a microcomputer to determine whether there is a push switch input combined from the push switch recognition means to perform a setting function and drive the relay unit.

In addition, the present invention is a single function key process for performing a single function by determining whether or not for a simple operation when the push switch is pressed; A setting mode determining step of determining whether the mode is for setting in a time delay manner when it is not input as a single function key in the function key process; An object of the present invention is to provide a method of setting a setting switch function of an electric shutter that sequentially performs a corresponding setting mode performing step of performing a corresponding setting mode determined in the determination process.

In the above, the present invention preferably includes a reverse phase detection unit for determining when it is connected to the input power of the motor in reverse phase and applying it to the microcomputer. In addition, it is preferable to add an alarm means for warning the alarm according to the instructions of the microcomputer at the time of reversed phase.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 4 is a block diagram of the present invention, preferably a semiconductor sensor for detecting the rotation of the driven gear (12-3) in conjunction with the drive gear (6-2) in conjunction with the shaft (6-1) of the moto (6) The reverse phase detection unit 140 which detects whether the input power phase of the input power phase of the motor 120 and the push switch recognition means 150 and the motor 6 recognize the operation state when the operation unit 120 and the push switch 7 are operated. The reverse phase detection unit 140, the semiconductor sensor unit 120, and the push switch recognition unit 150 receive data from the reverse phase alarm unit 160 and operate the electronic relay unit 130 according to a setting value. It consists of a microcomputer 110 for controlling to drive.

Examples of the push switch recognition means 150 are coils 151, 152, 153 and magnets 151, 152, 153 that are magnetized when the switches 7-1, 7-2, 7-3 of the push switch 7 are turned on. It can be exemplified by the configuration of the contact (154, 155, 156) for applying a high level to the microcomputer corresponding to the magnetization.

The operation of the present invention will be described below with reference to the flowchart of FIG.

5 is a single function key process 200 for determining whether it is for a simple operation when the push switch 7 is pressed to perform a single function; A setting mode determination step 300 of determining whether the mode is for setting in a time delayed manner when it is not input by a single function key in the process; The corresponding setting mode performing process 400 for performing the corresponding setting mode determined in step 300 is sequentially performed.

Specifically, the single function key process 200 reads and determines which switches 7-1, 7-2, and 7-3 are turned on by the pressing action of the push switch 7 shown in FIG. 4. 210)). Subsequently, the corresponding process (221, 222, 223) is performed according to which switch (the key is also used) is pressed.

On the other hand, if the single key input in step 210, the setting mode determination process 300 is performed. In other words, if it is not a single key input, it may be simply pressed together by mistake. Therefore, it is determined whether the same key is continuously pressed even after a predetermined time delay (step 310). Subsequently, it is determined whether the pressed key is a set, and then the process of performing the corresponding setting mode 400 is performed (step 320).

If it is determined in step 320 that the set key, and performs the corresponding setting mode execution step 400, and performs the corresponding setting mode (step 410). If it reaches the desired up / down setting position during execution, it is determined whether the stop switch 7-3 is pressed, and when it is pressed, the setting is finished and finished. In the process 420 has been described without setting the upper and lower settings, it will be appreciated that once the rising limit position is set and then the lower limit position is set.

As described above, the electric shutter of the present invention presses the lift switch 7-1 at the time of installation to raise the shutter, and when the lift limit position is reached, the push switch 7 is combined (for example, the lift switch 7-1 and the stop). When the combination of the switches 7-3 is pressed at the same time is set as the rising limit setting key, the value at that time (the number of revolutions detected by the semiconductor sensor unit 120) is stored in the microcomputer 110. In addition, the lower switch 7-2 of the push switch 7 is pressed to lower the slat 1, and at the lowest position at that time, the set combination switch 7 is operated to set the lower position on the microcomputer 110. Use it. At this time, since the semiconductor sensor unit 120 is a simple structure that interlocks with the shaft of the motor 6, there is no fear of wear.

As described above, the present invention has a built-in electronic semiconductor sensor unit, a microcomputer, and the like in the limiter, and the setting switch function can be set by limiting the setting position by the combination of the pressing switch. In addition, even if the upper and lower limits are continuously detected by the semiconductor sensor unit, light (light) is used as a sensing element with almost no mechanical friction, thereby improving reliability of the product due to almost no malfunction and wear. In addition, it is easy to install and operate because the upper and lower limit setting positions can be set only by the existing push switch operation.
