Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a wireless signal device for an electric shutter.

[Problems to be solved by the prior art and the invention] Generally, when remotely controlling the opening, closing, stopping, etc. of an electric shutter, an antenna, a receiving section, a transmitting section, etc. are provided, and the presence of obstacles during descent is required. When the shutter curtain is detected, it receives wireless transmission means such as light, radio waves, and sound waves to lower or stop the shutter curtain.
Various safety devices are installed, such as raising the ceiling. Depending on the installation position, it may be difficult to receive signals from these receivers and transmitters, so when installing them, it is necessary to select a position that provides the best sensitivity and also provides the best appearance. However, conventionally, when performing these installation adjustments and operation tests by one person, even if the transmitting section sends out a test signal, the receiving section does not have to confirm whether or not it has been received. Therefore, when a worker is forced to work alone, the reality is that the worker relies on his or her intuition.

[Means for solving the problem] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a wireless signal device for electric shutters that can eliminate these drawbacks. In an electric shutter configured to control the opening/closing/stopping of a shutter curtain by receiving an operation control signal with a receiver, the transmitter is tested to see if the transmitter is in an appropriate position. the test switch, a test signal associated with the operation of the test switch, and the operation control signal, and based on the determination that the signal is a test signal, a test signal of a mode different from the operation control signal is transmitted. The receiver side is provided with a signal discrimination means for discriminating the test signal mode from the transmitter from other signal modes, and is connected to the discrimination of the test signal mode by the signal discrimination means. The device is characterized in that it is provided with a notification means that operates as follows.

According to the present invention, with this configuration, it is possible to confirm whether or not reception has been achieved by knowing whether or not the notifying means responds to the operation of the test switch.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawing, 1 is an electric shutter, 2 is a shutter curtain constructed by rotatably interlocking a plurality of slats 2a, 2b is a bulge such as a connecting part of the slats 2a, and 2c is a seat plate. be. 3 is a shutter control panel, 4 is a limit switch, 5 is an opening/closing machine for the electric shutter 1, 6 is a ceiling lintel, and 7 is a shutter curtain 2.
A seat plate switch 8 provided on the seat plate 2c is a receiver, and a receiving section 8a provided on the lintel 6 is connected to the receiver 8. 9 is a manual push button switch, and 10 is a transmitter that issues a detection signal based on the obstacle detection signal from the seat plate switch 7, and the transmitter 10 is installed directly on the seat plate 2c or installed on the lower slat 2a. Attached to the back. If there is an obstacle while the shutter curtain 2 is lowering, the seat plate switch 7 comes into contact with the obstacle and detects it, and the transmitter 10 emits an emergency detection signal. The signal is received by the section 8a, and is further sent to the shutter control panel 3 via the receiver 8 to perform controls such as emergency stop of the shutter curtain 2. Note that 8b is a notification means provided within the receiver 8.

Reference numeral 11 denotes an elongated prismatic case that houses the transmitter 10, and is provided with outlets 12 at both ends for plugging in a connector, and a battery cover 13 for setting batteries on the side. This outlet 12 is designed so that a connector from the seat plate switch 7 can be connected from either the left or right side. Note that 14 is a transmission surface for sending optical signals, and a light emitting body 16 such as a light emitting diode (LED) is provided inside. This transmitting surface 14 is provided at a position as far away from the curtain surface as possible so that the signal light is not obstructed by the bulging portion 2b such as the slat connecting portion of the shutter curtain 2. In addition, 15 is a push button type test switch, which is provided on one end surface of the transmitter case 11.
It is used when attaching the transmitting section 10 and the receiving section 8a and for testing purposes.

Next, the control circuit diagram in which the present invention is implemented is shown in the fourth section.
This will be explained using the block diagram shown in the figure. The signals from the seat plate switch 7 and the test switch 15 are different mode signals, and are input to a control section 30 configured by microcomputer control (or may be electrical control). In the control unit 30,
The input signal determining unit 31 determines which mode signal the input signal is, and based on the result, if the input signal is a detection mode signal from the seat plate switch 7, it is a detection signal. Output starting section 3
2, and if it is a test mode signal from the test switch 15, an operation command is issued to the test signal output starting section 33. The starting sections 32 and 33 that have received these commands correspond to the transmitting section 10. In this case, the signal transmitted from the transmitter 10 is a different type of mode signal, and the output is set to be weaker in the case of a test signal.

On the other hand, on the receiving section side, the receiving section 8a receives the above two types of mode signals, and in the receiver that receives the receiving mode signal from the receiving section 8a, the discriminating circuit section 8c performs signal discrimination. The circuit section 8d distinguishes which mode signal it is, and if the received signal is a detection signal, it outputs a detection signal to the shutter control panel 3 to make an emergency stop of the opening/closing machine 5, and also outputs a test mode signal. If so, an activation signal is output to the notification means 8b to activate it.

In the embodiment of the present invention constructed as described above, when installing the transmitting section 10 or the receiving section 8a, the installation can be reliably carried out even by a single worker. That is, in the case where the present invention is implemented, when installing the transmitter 10, the transmitter 1
0 at a suitable position on the slat 2a, for example, and operate the test switch 15. If the position is favorable relative to the receiving section 8a, the notification means 8b will notify you, and if the position is unfavorable, the notification means 8b will notify you. If there is, the notifying means 8b will not make a notification, and therefore, even if the worker is working alone, the transmitting unit 10 will depend on the presence or absence of the notification from the notifying means 8b.
Since the optimum setting position of the transmitter 10 can be recognized and the transmitter 10 can be assembled, work efficiency can be significantly improved.

Moreover, since the signal output from the transmitter 10 is set to be smaller than that of the detection signal in the case of a test signal, when the transmitter 10 is set using this test signal, ,
The transmitter 10 is now set at a position with higher sensitivity, and therefore reliability can be significantly improved. In this case, it is safe even if the operating distance is reduced due to a drop in battery voltage or dirt on the transmitting surface.

It should be noted that this embodiment is, of course, not limited to the above-mentioned embodiment. For example, as shown in FIGS. 1 and 5, the mounting position of the antenna 21 for remote wireless operation may be set It can also be used for Here, 22 is a receiver dedicated to the antenna 21, and 22a is a notification means provided within the receiver 22. In this case, the handy type transmitter 20 is provided with a test switch 23, and the antenna 21 can be set at the optimum position by operating the test switch 23 and confirming the notification in the same manner as in the first embodiment. Moreover, this one is the transmitter 20
If a problem occurs in which the shutter curtain 2 does not operate even when the push button switch is operated, if there is a notification when the test switch 23 is operated, at least it can be determined that the problem is not related to the transmitter/receiver section, and this can also be avoided in terms of maintenance. Extremely useful.

[Operations and Effects] In short, the present invention is constructed as described above, so when installing the transmitter on the seat plate side, the receiver on the lintel side, and the antenna, the transmitter position can be changed to the transmitter. It is possible to quickly and accurately determine the presence or absence of notifications from the receiver side when the test switch is operated. Therefore, even when working alone, the set position of the transmitter and receiver can be accurately recognized. As a result, the occurrence of malfunctions such as malfunctions can be prevented, and reliability can be significantly improved.
