Description

technical field [0001] The present invention relates to the field of control, especially a pulse generator and a corresponding passive proportional control device, wherein the passive proportional control device includes the pulse generator and a corresponding proportional control unit, the pulse generator generates electricity and Energy support can be provided for the proportional control unit, and the pulse generator can send pulse signals to proportionally control the proportional control unit. Background technique [0002] Knob-type regulators are widely used in daily life. It is more intuitive to adjust some variables. For example, the knob-type dimmer switch used to adjust the brightness of the light is to adjust the voltage or current by rotating the knob. Change the brightness of the light. However, there are still many inconveniences in the application of the existing rotary switches. For example, the wired-controlled rotary switches need to arrange connecting wir...

Problems solved by technology

Existing passive wireless switches and self-sufficient high-frequency transmission devices cannot realize these functions, but people need such products in daily life

[0004] Specifically, although the passive switch has many advantages, it is undeniable that there are many technical problems that cannot be solved in the passive switch of the prior art, and precise proportional control cannot be realized, and there are many limitations in application. Specifically, The technical problem of the passive switch and energy self-sufficient high-frequency transmitting device of the prior art is:

[0007] The energy is not enough to realize the two-way communication mechanism where receiving and sending coexist

[0008] 2. It can only provide two simple instructions of on and off, and cannot provide continuous variable parameters to the device at the receiving end, nor can it realize proportional wireless control

[0009] 3. It cannot support the communication circuit to send and receive the standard wireless communication protocol; because the electric energy generated by the power generation device in the prior art is very limited, there is not enough time to support the transmission of the complete standard communication protocol

[0010] 4. The electric energy exists for a short time, cannot continuously send data information, has a high error rate, and is susceptible to interference

[0011] 5. The generated power is limited, and frequency hopping wireless communication cannot be realized. It can only be transmitted at a single frequency, and the signal is easy to be blocked.

[0012] 6. It can only drive extremely low power consumption circuits, which is expensive and difficult to popularize

[0013] In today's world with highly developed science and technology, robot technology, intelligent control technology, and multi-channel digital frequency hopping communication technology are widely used in all walks of life. In these fields, the use of passive digital proportional wireless control products has the advantages of convenient operation, maintenance-free, long-term The advantages of life and ease of use; however, energy self-sufficient high-frequency transmitting devices of the prior art cannot be applied in these fields
