Problems solved by technology
[0004] For some occasions with multiple roller shutters, such as shopping malls, office buildings, hotels, etc., if the corresponding unique corresponding switch must be operated for each roller shutter, it will cause great inconvenience and cause great harm to manpower. a lot of waste
[0005] Moreover, under normal circumstances, the connecting wires between such motors and switches are generally relatively short, which is not suitable for some engineering applications

Embodiment Construction
[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0019] see figure 1 and Figure 5 , a tubular motor switch system, which can be applied to the fields of roller blinds, opening and closing curtains, etc., includes a plurality of tubular motors 1 and switches.
[0020] The tubular motor 1 includes a motor main control chip and a motor end circuit 11. The terminals of the motor end circuit 11 have a first output terminal CN1, a first input terminal CN2 and a second input terminal CN3. The first output terminal CN1 is connected to a high level, and the first input terminal CN2 and the second input terminal CN3 are connected to the main control chip of the motor.
[0021] see figure 2 Alternatively, on this basis, the first output terminal CN1 of the motor end circuit 11' is connected to the cathode of the first diode D1, and the anode of the first diode D1 is connected to the high-level VCC...

The invention discloses a tubular motor switching system, comprising a plurality of tubular motors and switches, wherein the switches comprise multiple sub-control switches; the tubular motors is characterized by also comprising a motor end circuit; the switches comprise group control switches; a first sub-control terminal of each sub-control switch is connected with a terminal of the motor end circuit; and a first group control terminal of each sub-control switch is connected with a second sub-control terminal of each group control switch. The tubular motor switching system can operate one driven device and also can operate multiple driven devices simultaneously, thus being convenient to use. The high levels of the higher voltages are adopted for power supply input ends of the circuits, so that the voltages are increased, that is, the transmission distance is increased, thus enlarging the distance between the switches and a motor so as to adapt to the different occasions. The transmission of earth wire signals is cancelled, thus improving the anti-interference capacity.
Description
technical field [0001] The invention relates to a switching system for a tubular electric machine with a plurality of switches. Background technique [0002] As people's requirements for the quality of life are getting higher and higher, the application range of electric curtains is becoming wider and wider, and various electric curtains are becoming more and more mature. [0003] In the existing motor-driven electric curtains, taking the motor drive system in the roller blind as an example, the tubular motor drives the roller blind to automatically rise and fall, so as to realize the automatic use of the roller blind. A tubular motor drives a set of rope reels, lifting ropes, etc., and is equipped with a switch to control the motor. That is to say, at present, the shutter is usually controlled by a local switch or remote control, and the local A switch or remote control is uniquely associated with a roller shutter device. [0004] For some occasions with multiple roller s...
