Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of remote control switches, and specifically relates to a remote control switch circuit. Background Technology
[0002] Currently, with the rapid development of automation technology, more and more automated equipment is being widely used in industrial production, smart homes, agricultural irrigation, and many other fields. Among these automated devices, remote control switching has become a fundamental and crucial feature, enabling users to remotely control the equipment, greatly improving operational convenience and flexibility. However, in current applications of remote control switching technology, a significant problem has gradually emerged: although many automated devices already possess the ability to be controlled via remote control signals, these devices often exhibit relatively crude processing of these signals.
[0003] Specifically, existing remote control switch circuit designs are often overly simplistic and direct. Upon receiving a remote control signal, they lack effective signal processing and verification mechanisms, simply converting the received signal directly into a switching action. While this direct approach is simple and efficient, it has significant drawbacks: unstable signal quality, and even errors or signal loss. Because existing remote control switch circuits lack effective processing for these unstable signals, they often directly lead to unstable control of the device's switching when the signal is unstable, resulting in malfunctions, inability to start or stop the device properly, and other problems. This not only affects the normal operation of automated equipment and reduces production efficiency but may also damage the equipment itself and increase maintenance costs.
[0004] Therefore, there is an urgent need to provide a remote control switch circuit that can improve remote control stability. Utility Model Content

These terms are only used to distinguish one unit from another.

In addition, the character " / " that may appear in this document generally indicates that the related objects before and after it are in an "or" relationship.
[0035] Example 1:
[0036] like Figure 1 As shown, this embodiment provides a remote control switch circuit, including: a remote control communication unit, a signal control unit, and a switch response unit;
[0037] The remote control communication unit is connected to a remote control signal generator at its communication terminal. The signal output terminal of the remote control communication unit is electrically connected to the signal input terminal of the signal control unit. The signal output terminal of the signal control unit is electrically connected to the signal input terminal of the switch response unit. The switch signal output terminal of the switch response unit is electrically connected to the switch signal input terminal of the appliance.
[0038] It should be noted that the remote control signal is received through the remote control communication unit, and then the remote control signal is repeatedly processed by the signal control unit to make the control of the appliance by the remote control signal more stable and prevent problems such as equipment malfunction. Finally, the automatic control of the equipment is completed through the switch response unit, which improves the stability of the remote control.
[0039] Example 2:
[0040] like Figure 2 As shown, this embodiment provides a remote control switch circuit. In one possible implementation, the remote control communication unit includes a four-channel self-locking wireless receiver controller 6.
[0041] The communication terminal of the four-channel self-locking wireless receiver controller 6 serves as the communication terminal of the remote control communication unit and is connected to a remote control signal generator. The four-channel self-locking wireless receiver controller 6 includes a first output port, a second output port, a third output port, and a fourth output port. The first output port, the second output port, the third output port, and the fourth output port all serve as signal output terminals of the remote control communication unit and are electrically connected to the signal input terminal of the signal control unit.
[0042] It should be noted that the four-channel self-locking wireless receiver controller 6 is equipped with four independent output channels (output ports), each of which can independently control the on / off state of an appliance, such as the forward and reverse rotation of a motor, or the on / off state of a power supply. Furthermore, when a remote control signal is emitted from the remote control signal generator, the four-channel self-locking wireless receiver controller 6 receives the signal and, through its self-locking function, activates and holds the corresponding self-holding relay 12 until the same remote control signal is received again. This function allows the controller to stably maintain the on / off state of the device, avoiding malfunctions caused by unstable remote control signals.
[0043] When the four-channel self-locking wireless receiver controller 6 outputs a low frequency, it directly controls the COO5 delay chip 8, causing the COO5 delay chip 8 to output a low frequency for a short time, and then switch to high frequency output. When the four-channel self-locking wireless receiver controller 6 outputs a high frequency, one channel switches to low frequency output through the driver chip to control the COO5 delay chip 8, causing the COO5 delay chip 8 to output a low frequency for a short time, and then switch to high frequency output.

[0048] In one possible implementation, the drive control subunit includes a drive chip, the delay control subunit includes a first delay chip, a second delay chip, a third delay chip, a fourth delay chip, a fifth delay chip, a sixth delay chip, a seventh delay chip, and an eighth delay chip, and the jog detection subunit includes a first detection chip and a second detection chip.
[0049] Wherein, the first output port is electrically connected to the first input pin of the first delay chip and the first input pin of the driver chip respectively; the first output pin of the driver chip is electrically connected to the input terminal of the second delay chip; the second output port is electrically connected to the second input pin of the third delay chip and the second input pin of the driver chip respectively; the second output pin of the driver chip is electrically connected to the input terminal of the fourth delay chip; the third output port is electrically connected to the third input pin of the fifth delay chip and the third input pin of the driver chip respectively; the third output pin of the driver chip is electrically connected to the input terminal of the sixth delay chip; the fourth output port is electrically connected to the fourth input pin of the seventh delay chip and the fourth input pin of the driver chip respectively; and the fourth output pin of the driver chip is electrically connected to the input terminal of the eighth delay chip.

[0052] The input pin of the ULN2804L chip 11 is electrically connected to the output terminal of the jog detection subunit. The output pin of the ULN2804L chip 11 is electrically connected to the input terminals of the first switch signal output relay, the second switch signal output relay, the third switch signal output relay, and the fourth switch signal output relay, respectively. The output terminals of the first switch signal output relay, the second switch signal output relay, the third switch signal output relay, and the fourth switch signal output relay are electrically connected to the switch signal input terminal of the appliance.
[0053] It should be noted that the ULN2804L chip 11 is an eight-channel Darlington transistor driver chip. It drives the output through NMOS transistors and has eight output channels. Each output channel has a built-in freewheeling diode, which can effectively suppress the reverse electromotive force generated when the load is turned off and protect the drive circuit from transient high voltage impact.
[0054] In one possible implementation, the driver chip is a ULN2003 chip 7, the first delay chip, the second delay chip, the third delay chip, the fourth delay chip, the fifth delay chip, the sixth delay chip, the seventh delay chip and the eighth delay chip are all COO5 delay chips 8, and the first detection chip and the second detection chip are both transistor array driver chips 9 controlled by jog mode.
[0055] It should be noted that the ULN2003 chip 7 consists of seven silicon NPN composite transistors. Each pair of Darlington transistors is connected in series with a 2.7kΩ base resistor. It also integrates seven common-cathode freewheeling diodes to provide current for switching operations. The ULN2003 chip 7 has seven channels, each capable of independently driving a load, making it well-suited for the multi-channel control scenario in this embodiment. Furthermore, the seven common-cathode freewheeling diodes protect the chip from back EMF damage generated by the appliance, improving circuit reliability and stability. The COO5 delay chip 8 implements a delay control function upon receiving the remote control signal, ensuring orderly input of multiple signals and guaranteeing remote control stability.
[0056] In one possible implementation, a power management unit is also included;
[0057] The power input terminal of the power management unit is electrically connected to the mains power, and the power supply terminal of the power management unit is electrically connected to the power supply input terminals of the remote control communication unit, the signal control unit, and the switch response unit, respectively.

[0063] It should be noted that a safety capacitor is connected between the neutral and live wires connected to the mains power. Furthermore, the power supply step-down subunit 1 preferably converts the 220V mains input to a 5V step-down output, and outputs the stepped-down 5V voltage to the signal relay subunit 2 and the uninterruptible power supply subunit 3 (UPS). When the mains power is output, the UPS subunit 3 prioritizes charging the lithium battery storage unit 5 (the lithium battery storage unit 5 can preferably be a 3.7V lithium battery). After it is fully charged, it stops charging the lithium battery storage unit 5. When the mains power is not output, it can cut off the reverse current from the lithium battery storage unit 5 to the UPS subunit 3 to save power consumption. The self-resetting fuse subunit 4 can be used to protect the downstream circuits.
[0064] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model.
