Fig. 1 is a block diagram of a multimode communications controller according to an embodiment of the present application. As shown, the multimode communication controller 100 comprises:

and the multimode communication module 110 is configured to receive an illumination control instruction sent by an external control terminal, and perform transparent transmission in one or more communication modes.

In the embodiment of the present application, the multimode communication module 110 includes, but is not limited to: any one or more of a ZigBee communication module, a Bluetooth communication module, a power line carrier communication/micro power wireless communication module and a DALI communication module.

Further, the external control terminal corresponds to each communication module in the multimode communication module, and includes but is not limited to: any one or more of a cloud server, a portable control terminal (such as a smart phone or a remote controller), a control panel, a sensor and an intelligent gateway.

In the intelligent lighting in the intelligent home, the full connection, the convenient operation and the safety of the whole home equipment need to be considered, more networking nodes need to be considered, the networking is complex, and some nodes such as a sensor, a remote controller and the like also need to support low power consumption. Then ZigBee is certainly the best choice at this stage because ZigBee has a mature application layer protocol in smart homes to support interworking between whole-house devices. The bluetooth technology defines a bluetooth Mesh technology based on controllable broadcast, inherits the characteristic of bluetooth low energy consumption and the characteristic of direct control without a gateway mobile phone APP, and is also a connection technology worthy of attention in the future.

In this embodiment, the ZigBee communication module communicates with a serial port of a control module (such as a single chip), and is based on a globally uniform application layer protocol (such as ZHA and ZigBee3.0) so as to be applied to linkage and lighting control of whole-house devices in smart homes. For example, a controller containing a ZigBee module may support ZigBee remote controller control, smart phone APP control in conjunction with a ZigBee gateway, or cloud server control in conjunction with a ZigBee gateway.

In this embodiment, the bluetooth communication module communicates with a serial port of a control module (such as a single chip). Because the intelligent mobile phone can be directly communicated with the Bluetooth module on the intelligent mobile phone, the Bluetooth MESH technology is combined with the Bluetooth audio processing technology, and the cool and dazzling effect of sound-light rhythm is easily formed in the lamp; in addition, the bluetooth lamp is also advantageous in value-added services based on the bluetooth lamp, such as indoor positioning, navigation, shopping guide, information push and other services. Like this, the multimode communication controller described in this application can support control of bluetooth remote controller, or smart mobile phone APP control etc..

The power line carrier communication (PLC)/micro-power wireless communication module applies a technology of broadband PLC and micro-power wireless dual-mode communication, the technology is widely applied to indoor electric energy meter reading services, and the power line carrier communication (PLC)/micro-power wireless communication module is a typical representative of cooperative fusion of wired communication and wireless communication. The dual-mode communication technology is applied to the integration of an intelligent lighting control system, the respective advantages of wired and wireless communication technologies can be fully utilized, communication blind spots are eliminated, the problem that the working stability and reliability of a lamp control system are affected by the communication blind spots in the existing indoor wireless lamp control system is solved, and the problem that a special control signal wire must be laid in the existing wired lamp control system is also avoided.

In the embodiment, the power line carrier communication utilizes the electric wire connected with the electric appliance or the terminal equipment to carry out communication and data transmission, does not need extra wiring, is convenient to implement, can pass through a wall and cross the wall, and is not blocked. However, power line carrier communications are susceptible to noise and interference on the power grid. The micro-power wireless communication transmits data in the air through radio frequency electric waves, is not influenced by noise and interference on a power grid, but is easily influenced by wall blocking, metal shielding, weather environment and the like.

The power line carrier communication (PLC)/micropower wireless communication module disclosed by the application, for example, a power line carrier/micropower wireless monolithic communication chip LME2981 which is advanced, miniaturized and rich in resources and can be used for secondary development and is pushed by force micro-electronics, can provide a better communication technical solution for four-meter centralized meter reading and other intelligent internet of things. The dual-mode low-power-consumption integrated circuit is integrated in a single chip with the size of 7 mm multiplied by 7 mm, adopts 48-PIN LQFP packaging, gives full play to the advantages of two communication technologies, makes up the defects of the two communication technologies, realizes dual-mode simultaneous communication and solves the problem of reliable communication. Meanwhile, the cost and the power consumption are both provided with the condition of large-scale use through a highly integrated chip.

In this embodiment, serial communication between the power line carrier communication/micropower wireless communication module and the control module (such as a single chip microcomputer) does not have a ready lighting control bus in the lighting reconstruction of the built building, and new laying has a large engineering quantity and a long construction period. In this state, it is a reasonable choice to adopt an intelligent lighting system integrating a power line carrier communication (PLC)/micropower wireless communication module. The system eliminates communication blind spots based on a mode of cooperative fusion of power line wired communication and wireless communication, solves potential communication obstacles such as more rooms and more obstacles in a building and ensures stable communication and reliable illumination control. Thus, the multi-mode communication controller described herein may support power line carrier communication (PLC)/micro power wireless panel control, or cloud server control in conjunction with power line carrier communication (PLC)/micro power wireless gateway.

As intelligent lighting in intelligent buildings typically needs to be linked with building automation systems, bus-based connection means in building automation have been applied in large numbers, such as KNX, BAcnet or Dynet, which can be used to control lighting. For lighting equipment, DALI is the first choice of lighting connection technology due to advantages of globalization standard, simplicity, reliability, easy installation, etc. The DALI protocol is a digital addressable lighting interface, and is a data transmission protocol that defines the communication mode between the electronic ballast and the device controller, and is not a system with any complex control function, but is a data transmission protocol of a light control subsystem.

In this embodiment, the DALI communication module preferably communicates with a GPIO serial port of a control module (e.g., a single chip microcomputer). Most intelligent buildings are built based on bus technology. The building equipment automation linkage needs reliable connection, and for lighting equipment, the DALI technology is globally unified in standard, simple, reliable and easy to install. In this way, the multimode communication controller may support DALI panel control on a DALI bus or KNX panel control based on a KNX/DALI gateway.

In particular, the control panel may be part of a user interface on the smart terminal, and may also be a lighting control panel provided on a wall.

The intelligent gateway can realize 3-network (telecommunication, broadcasting and television, broadband) integration equipment and is also a bridge for local area network and external communication. The intelligent gateway in the application can be a traditional router, CATV and IP distribution, and can also have wireless forwarding and wireless receiving functions, namely, the intelligent gateway can convert external communication signals into wireless signals so as to receive the wireless signals in any corner, and simultaneously can receive the signals and further control other terminal equipment when a remote control device or a wireless switch is operated.

The portable control terminal comprises a terminal which can be remotely controlled, such as a smart phone, a PAD, a remote controller and the like.

The lighting control instruction sent by the multi-mode communication module 110 is received by the external control terminal, such as an LED switch or a color modulation control instruction, for example, by means of a physical key or gateway communication.

A control module 120, which is provided with a serial port in communication connection with each communication module in the multi-mode communication module 110 and includes an application protocol corresponding to each communication module; the control module 120 is configured to receive the lighting control instruction transparently transmitted by the multimode communication module 110, and analyze an application layer protocol included in a communication signal corresponding to the lighting control instruction to obtain a control signal, so as to control the LED lamp correspondingly.

In this embodiment, the control module 120 is preferably an ARM single chip microcomputer, and based on a communication protocol agreed among the devices in the communication link, the control module 120 is configured to receive and analyze an illumination control instruction sent by a superior illumination control terminal (e.g., a control panel, an intelligent gateway, etc.), and process and convert the illumination control instruction into a control signal adapted to the LED driving power.

Specifically, the control module 120 is configured to receive an instruction transmitted by the multimode communication module 110, and process a communication signal application layer protocol and decide an intelligent lighting control signal or process intelligent lighting control logic.

The control module 120 may also be a general-purpose Processor, including a Central Processing Unit (CPU), a Network Processor (NP), and the like; it may also be a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA) or other Programmable logic device, discrete Gate or transistor logic device, or discrete hardware components.

In the embodiment of the present application, the control module 120 is provided with a sensor adapting interface, configured to adapt to access one or more sensors to obtain one or more sensing information data, and send the sensing information data to the external control terminal through the multi-mode communication module; the sensing information data includes: any one or more of personnel perception information, environment perception information and equipment operation information.

In this embodiment, the control module 120 integrates a sensor interface module to adapt to an external sensor probe on the multi-mode communication controller, such as various sensors commonly used in intelligent lighting, such as air quality, environmental noise, climate, natural light, motion, and occupancy, to sense human information, environmental information, and operation information of the lighting device itself. These sensors are of a wide variety of types and specifications and have different respective output signal types. The sensor adaptive interface module can convert output signals of different sensors, such as analog quantity in formats of 0-5V, 4-20 mA and the like or digital quantity in an I2C format, into a uniform digital signal type so as to be accurately acquired by a GPIO port of a single chip microcomputer in the multi-mode communication controller. Obviously, the sensor interface module is integrated in the multi-mode communication controller, so that the adaptation difficulty of the intelligent lamp and the sensor can be obviously reduced, and the repeated workload in the research and development of the multi-mode communication controller can be obviously reduced.

In this embodiment, the control module 120 can identify the currently functional module by detecting whether the signal corresponding to the access of each communication module or sensor is present or absent. For example, calling individual blocks corresponding to individual modules to resolve application layer protocols contained in the communication signal, or calling intelligent lighting application blocks to perform appropriate application configuration or control methods, such as: the method comprises the following steps of lamp grouping/scene attribute configuration and calling, sunlight collection control, dynamic and static induction control, time centralized control, real-time use control, lamp state polling reporting, failed lamp real-time alarming and the like.

In an embodiment of the present application, the control signal includes: the switching signal and the dimming signal.

In addition, the types of the control signal include: any one of an analog signal, a PWM signal, and a digital signal.

Preferably, the LED driving power is used for receiving a control signal, such as a switching signal and a dimming signal, sent by the control module 120, and performing a switching or dimming operation of the LED lamp. The type of the control signal transmitted to the LED driving power source may be, but is not limited to, a 0-10V analog signal, a 0-100% PWM signal, or other digital signals such as DALI, 485.

On the premise of following a uniform application layer protocol, the lighting service instruction signal sent by the external control terminal is transmitted by the multimode communication module 110, and the transmitted control instruction is received and identified by the control module 120 and then converted into a switching or dimming instruction adapted to the LED driving power supply.

In this embodiment, each communication module protocol stack in the multimode communication module 110 adopts a 4-layer software architecture, which includes: namely, a physical layer, a MAC layer, a network layer, and a service application layer.

For example, a communication protocol stack of the power line carrier communication/micro-power wireless communication module adopts a simplified 4-layer architecture, namely a physical layer, an MAC layer, a network layer and a service application layer, and is widely applied to an indoor electric energy meter reading service. In order to simply apply the multimode communication module 110 to indoor lighting control application, in the present application, a communication protocol with a 4-layer architecture is still used to implement intelligent lighting control, and the contents of protocol stacks of a physical layer, an MAC layer and a network layer are used, and information is transmitted between equipment nodes in a communication link, and only the contents of the protocol stack of the application layer are modified, that is, the indoor power meter reading service protocol stack is modified into the intelligent lighting control service protocol stack.

Specifically, each communication module protocol stack adopts a 4-layer software architecture, and specific functions of each layer are as follows:

physical layer: the PLC electrical characteristics and the micro-power wireless radio frequency characteristics of the communication medium interface are defined, such as frequency band (471 MHz-486 MHz) required by radio frequency communication, modulation mode FSK, receiving sensitivity RSSI, energy detection of the current working channel, idle channel estimation, channel switching and the like.

MAC link layer: define channel access patterns and select reliable communication links, such as to support CSMA-CA and TDMA control mechanisms.

Network layer: building a network in a designated channel, adding new equipment to the network, planning optimal routing and data transmission among the equipment, and the like.

An application layer: defining a lighting control frame structure and a byte structure; defining a control instruction set; the types of devices in the network are defined, such as control panel nodes, intelligent gateway nodes, intelligent lighting nodes, etc.

It should be noted that, the utility model discloses in, because information passes through between each network equipment node, so the illumination control instruction that external control terminal sent can be correctly unscrambled and carried out by the terminal LED intelligence lamps and lanterns node of lighting system, the key is that there is unified application layer agreement between external control terminal and the intelligence lamps and lanterns.

For example, the structure of the frame in the application layer protocol is shown in table 1 below.

Table 1 frame structure in application layer protocol

Table 1 shows a frame structure in an application layer protocol, which is used to agree on a signal format for mutual communication between an external control terminal and the multimode communication controller 100, and is a necessary condition for interconnection and interworking between network device nodes in the entire communication link. In addition, part of the lighting control codes in the application layer protocol may be as shown in table 2 below.

Table 2 partial lighting control codes in application layer protocol

Control code	Function(s)	Direction of transmission
			0AH	Terminal type active reporting	Terminal->Lighting gateway

			1DH	Total time of zero clearing work	Lighting gateway>Terminal device
1EH	Zero clearing total electricity consumption	Lighting gateway>Terminal device
			20H	Query voltage	Lighting gateway>Terminal device

Table 2 shows that, based on a part of control codes of lighting control in an application layer protocol, the multimode communication controller 100 according to the present application can recognize the meaning of control commands sent by external control terminals such as a cloud server, a portable control terminal, a control panel, a sensor, and an intelligent gateway, so as to determine a correct intelligent control signal for a driving power supply.

Specifically, the power module 130 generates a dc voltage suitable for the multimode communication module 110 and the control module 120, respectively, to provide power to them, although the power module 130 may also provide power to the LED driving power adapted to the control module 120.

In summary, in the multi-mode communication controller 100 described in the present application, the multi-mode communication module 110 is integrated, and a sensor interface module can also be integrated, so as to improve adaptability of the whole luminaire to different application scenarios, such as intelligent lighting in an intelligent home, intelligent lighting in building reconstruction, and intelligent lighting in an intelligent building.
