Description

Technical Field

[0001] The utility model relates to the field of three-color temperature lamp control circuits, and particularly to a multi-machine control system for multi-group three-color temperature lamp controllers. Background Technique

[0002] As the fourth-generation lighting source, the LED light source is gradually replacing the incandescent lamp and fluorescent lamp sources due to its significant energy-saving and long-life advantages. With the explosive development of the LED lighting industry in recent years, in addition to the consistent requirements for the stability of lamps, the multi-functional three-color temperature style floodlights have also brought increasing popularity. However, when the existing three-color lights are controlled, the control of each group of lights is independent of each other, resulting in the need to set up a serial port control module for each group of control systems, leading to a high usage cost and poor system stability.

By adopting the technical solution of the utility model, the reverse logic of MOS and switch device switching control can be used to achieve three-color temperature hybrid control, reduce the usage amount of components, reduce the product cost, reduce the volume of the PCBA, reduce the production time, and improve the production efficiency. The multi-group three-color temperature LED control circuits of this patent are not related to each other during use, and the control during use is independent of each other, resulting in a high cost. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that when the existing three-color lights are controlled, the control of each group of lights is independent of each other, resulting in the need to set up a serial port control module for each group of control systems, leading to a high usage cost and poor system stability. In view of the above defects of the prior art, a multi-machine control system for multi-group three-color temperature lamp controllers is provided.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] The RS485 circuit includes a set of host modules and at least one set of slave modules.

[0034] In order to make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0035] A multi-machine control system of a multi-group three-color temperature lamp controller of the preferred embodiment of the present utility model; as Figure 1 and Figure 5 shown, includes a communication circuit for accessing a control signal to the multi-machine control system of the three-color temperature lamp controller; an RS485 circuit for connecting to the AB bus, forwarding the signal received by the communication circuit to the AB bus, and sending the received communication signal as a TTL signal to the lamp control circuit; a lamp control circuit and a lamp for receiving the signal of the RS485 circuit and controlling the three-color temperature lamp to emit light.

[0036] Specifically, as Figure 3-4As shown in the figure, the RS transceiver module is provided with a set of host modules and multiple sets of slave modules. The host module and the slave modules are respectively connected to a set of lamp control circuits and control a set of three-color lamps correspondingly. The host module includes an RS485 control module, an RS485 transceiver module connected to the RS485 control module, and a device port. The device port is connected to the lamp control circuit and controls the lamp control circuit. Both the RS485 transceiver module and the RS485 control module are connected to the communication circuit. And the RS485 control module is connected to the serial port module, the RS485 transceiver module is connected to the AB bus port, and the AB bus port is connected to each set of slave modules. The difference between the slave module and the host module is that the slave module does not need to be connected to the communication circuit and does not need to be provided with a serial port module. When the host module receives the signal from the communication circuit and matches it through the serial port module, the RS485 control module converts the received signal into a TTL signal and sends it to the lamp control circuit to control the lamp, and at the same time sends it to the AB bus. The slave module directly receives data from the AB bus and converts it into a TTL signal for the lamp control circuit to process and then controls the operation of the three-color lamp. By receiving the signal from the communication circuit through the host module and matching it with the serial port module, the signal is converted and sent to the AB bus. The slave module directly controls the corresponding lamp control circuit, realizing the control of one host module, while the slave modules perform control synchronously, and each set of slave modules is independent of each other, avoiding packet loss or high cost caused by using multiple modules. Similarly, if the signal between the host module and the communication circuit does not match, the host module cannot convert the signal into a TTL signal and send it to the AB bus and the lamp control circuit. And the RS485 transceiver module can be used to receive and send relevant signals in the host module, while in the slave module, only its receiving signal is required and no signal sending is required. At the same time, the communication circuit can use a Bluetooth module for communication connection, which is the most convenient for transmission and has low cost.

[0037] Further, as Figure 2 shown, the lamp control circuit includes a lamp control module, and a power-off detection module, a main control power supply module, an output module, and a port module connected to the lamp control module. The output module is connected to the three-color temperature lamp to control the operation of the three-color temperature lamp. The port module includes a serial port connection port, a Bluetooth transmission port, an RS485 transmission port, and an RS485 reception port. The circuit resistance can be modified to the single-machine operation mode through the Bluetooth transmission port, which is used as a reserved port. The serial port connection port is used to burn relevant control algorithms for the control module, and receive and send relevant signals through the RS485 transmission module and the RS485 reception module. Among them, the RS485 transmission module connected to the slave module does not need to send signals.

[0038] Further, as Figure 5As shown in the figure, the signal is connected to the host module through the Bluetooth module. When the serial port connection module of the host module receives a signal that conforms to its serial port protocol, it is converted into a TTL signal and sent to the AB bus and the lamp control circuit through the RS485 module. The serial port connection module can adopt modules such as the DALL module, the Bluetooth module, and the ZigBeem module. The slave module directly converts the signal into a TTL signal through the AB bus and sends it to the lamp control circuit. Thus, one host module is matched with multiple slave modules, and the slave modules can be expanded as needed. Moreover, only the host module uses one serial port control module, which reduces the practical cost of the slave and has stronger anti-interference ability. The RS485 control circuit is used to transmit the control signal, which has stronger anti-interference ability, thereby improving the reliability of the system and reducing the hardware cost of the system. It should be noted that the RS485 control circuit can also be replaced with other circuits, enabling it to match the serial port connection module after being connected to the Bluetooth module, and convert it into a specific signal and send it to the AB bus, so as to expand the slave module, which should also belong to the protection scope of this utility model. The specific enumeration is not done in this utility model.

[0039] Further, as Figure 6-8 shown, the RS485 control module uses the CS32L010F8U6 chip, which has 20 groups of pins. The 11th to 13th pins are connected to the device port, the 4th pin is connected to the reset button, the 5th and 5th pins are connected to the RS485 transceiver module and the Bluetooth module, and the 7th to 9th pins are grounded and connected to the 3.3V power supply through capacitors and inductors arranged in parallel or series. The Bluetooth module is connected to the pins of the RS485 control module through the second resistor and the third resistor.

[0040] Further, as Figure 9-13 shown, the lamp control module uses the LQF32-CS32F030 chip, which is connected to the power-off detection module. When the power supply of the lamp control module is disconnected, it feeds back a signal to the lamp control module to perform the power-off processing task. The main control power supply module provides power for the lamp control circuit. And different function controls and outputs are realized by equipping various different ports.

[0041] Further, as Figure 14 shown, the output module includes lamp beads of three color temperatures, namely red, blue, and green color temperatures. The lamp control module transmits the control signal to the first chip U1 through an inductor. The first chip U1 uses UCC27517, and then is connected to the lamp through a group of resistors connected to a triode for control. It is also connected to the lamp control module through a resistor to realize output according to the duty cycle given by the lamp control module, so as to realize the combination of different color temperatures.

[0042] It should be understood that the present utility model is described through some embodiments. Those skilled in the art know that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the present utility model. Additionally, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present utility model.
