Along with the construction promotion of smart city, already lay more intelligent street lamps in the present city, on possessing the illumination function basis, still have functions such as data acquisition, data processing, demonstration, thing networking communication, can be used to satisfy various intelligent application scene demands.

The single-lamp controller is a terminal control device for controlling lighting lamps (such as the intelligent street lamp) in a lighting system, and the single-lamp controller commonly used in the market is mainly divided into a wired communication controller or a wireless communication controller according to a communication mode.

The communication stability of the wired communication controller is better, the installation cost is lower, but the wired communication controller is constrained by cables.

Common wireless communication protocols of the Internet of things are Zigbee, NB-I/OT, loRa and the like. The communication effect of the ZigBee communication system is affected by factors such as the place where the antenna is installed and the installation direction. The NB-I/OT communication mode has few base stations, limited use region, few communication downlink channels and poor communication concurrency performance, and is influenced by a third-party server in installation and debugging; the LoRa communication mode needs to be deployed with a base station, has high cost, no broadcasting mechanism, poor batch dimming consistency effect and poor anti-interference performance, and is extremely easy to be interfered by signals.

Currently, a single lamp controller for a lighting fixture (e.g., a smart street lamp) has a problem of a single communication mode, and the adopted communication mode has a problem of insufficient communication functions in an actual scene, such as stability and convenience in installation and arrangement, due to limitations.

In view of this, embodiments of the present disclosure may provide a single-lamp controller, which provides a multi-mode communication manner, so as to solve the problems in the prior art. The single lamp controller may be mounted to each lighting fixture, the lighting fixture comprising at least one lighting unit. The lighting fixture may be a street lamp and the lighting unit may be a lamp head of the street lamp. In some embodiments, the street lamp may have two lightheads, and the single lamp controller may control the illumination of the two lightheads.

As shown in fig. 1, a block diagram of a single lamp controller in an embodiment of the present disclosure is shown.

The single lamp controller comprises a main control unit module 101, a lamp control unit module 102, a communication module with multiple modes and a power supply module 103.

The power module 103 is connected to an external power source and converts it into an internal power source. Illustratively, the power module 103 may include an ac to dc module and a voltage conversion module, and the external power source is ac. The ac-dc conversion module in fig. 2 is used to convert the input ac power into 12V dc power. In some embodiments, the voltage conversion module may be selected according to the voltage value of the power required by each functional module, for example, the voltage conversion module includes a 12V to 5V module, a 12V to 3.8V module, and a 12V to 3.3V module, which convert the 12V dc power to 5V dc power, 3.8V dc power, and 3.3V dc power, respectively, and the 5V, 3.8V, and 3.3V dc power is connected to the power input terminals of each module (including, for example, the main control unit module 101, the lamp control unit module 102, the communication modules of multiple modes, and the remaining modules) to provide dc power input for each module.

The light control unit module 102 is communicatively connected to the main control unit module 101 and is connected to at least one path of lighting units. The lamp control unit module 102 is used to control lighting functions of the lighting unit, such as on/off of power supply, dimming, etc. In some embodiments, the light control unit module 102 includes: the lamp control switch module and the dimming control module. The lamp control switch module is used for controlling the on-off of the lighting lamp, and the dimming control module is used for controlling the dimming of the lighting lamp. In some embodiments, the lamp control switch module is used for controlling the lighting unit of the lighting lamp to be turned on or off. For example, the lamp control switch module 102 may output two AC switching signal outputs corresponding to two lamp heads to supply the on/off of each lighting unit in the lighting fixture, so the on/off of each lighting unit may be synchronous or independent. The dimming control module is used for controlling dimming of the lighting lamp. Illustratively, the single lamp controller may support 0-100% stepless dimming. Specifically, the dimming control module may receive the PWM signal output by the main control unit module 101, and output two paths of 1V-10V dc supply voltages to each lighting unit after filtering and operational amplification. For example, at a control voltage of 1V, the illumination luminous flux is minimal, such as 1%; at a control voltage of 10V, the corresponding luminous flux is maximum, for example 100%. In the dimming process, the control voltage and the luminous flux output by the lighting unit can be in a linear relation. In addition, dimming between each lighting unit may also be independent, that is, the main control unit module 101 may output two paths of PWM signals PWM1 and PWM2, and the dimming control module may include an output circuit of two paths of dimming signals (i.e., 1V-10V dc voltage signals), and particularly, referring to fig. 6, a schematic circuit diagram of the dimming control circuit in an embodiment of the disclosure may be shown. As can be seen, the left PWM1, PWM2 are input from two ends, respectively to the input of one op-amp in U5, and are output by the op-amp to the separate output circuits to output dimming signals, AOUT1 and AOUT2.

The communication module of multiple modes includes: the power line carrier communication module 104 and the internet of things mobile communication module 105 are all in communication connection with the main control unit module 101, and are respectively used for wired and wireless bidirectional communication between the main control unit module 101 and the outside. Because the wireless communication system has the capabilities of both wired (namely power line carrier communication) and wireless (mobile network communication), the single-lamp controller can switch and select the communication modes according to the environment, so that the stability of communication is improved, and the advantages of different communication modes can be utilized in the best and best way. Illustratively, the power line carrier communication module 104 may send data (such as electrical parameter data of the lighting fixture) to the outside through a wired communication manner, and may receive a control instruction for the lighting fixture through a wired communication manner. The mobile communication module 105 of the internet of things can send data outwards in a wireless communication mode based on a mobile wireless communication protocol of the internet of things, and can receive a control instruction for the lighting fixture.

In some embodiments, the power line carrier communication module 104 and the internet of things mobile communication module 105 operate redundantly, for example, the main control unit module 101 may detect whether the communication of the currently used communication module is normal, and switch to another communication module for use immediately upon detecting that communication with either the power line carrier communication module 104 or the internet of things mobile communication module 105 is lost, i.e. disconnected, within a unit period. Alternatively, in still other embodiments, the power line carrier communication module 104 and the internet of things mobile communication module 105 operate independently to process independent or cooperative tasks, such as processing the data transmission task 1 and the data transmission task 2 respectively by the power line carrier communication module 104 and the internet of things mobile communication module 105; or, the first part and the second part of the data sending task 1 are respectively processed by the power line carrier communication module 104 and the internet of things mobile communication module 105, so as to improve the communication performance.

Preferably, in some embodiments, the power line carrier communication module 104 comprises an HPLC communication module, and the internet of things mobile communication module 105 comprises a cat.1 communication module. The HPLC communication module is used for wired data transmission of the single lamp controller. The electrical parameter data of the lighting lamp can be sent outwards through an HPLC communication module (wired communication), and can receive control instructions sent from the outside. In some embodiments, the HPLC communication module may be connected to an ac power source through a voltage transformation module, where the voltage transformation module is configured to convert an input ac high voltage carrier signal into a low voltage communication signal, and transmit the low voltage communication signal to the HPLC communication module. The CAT1 communication module is used for wireless data transmission of the dual-mode communication single-lamp controller. Cat.1 is called LTE User Equipment-Category 1, is a Category of wireless performance of user terminal equipment in an LTE network, can directly multiplex LTE network resources built by the existing 4G base station, and can support middle-low speed Internet of things application. The CAT1 communication module in the embodiment of the disclosure can transmit the state data of the street lamp by means of the established existing wireless network and receive the control signal sent directly or indirectly by the control center.

In some embodiments, the single lamp controller further comprises: one of the following modules is communicatively connected to the main control unit module 101: a metering module 106; an angle detection module 107; at least one expansion communication module; and a power output module 108.

The metering module 106 is configured to meter electrical parameter data of at least one lighting unit. Specifically, when the lighting fixture is powered by ac, the electrical parameter data includes ac parameters, and the metering module 106 may collect and/or calculate other electrical parameter data according to the collected part of the electrical parameter data, so as to implement the function of measuring the electrical energy of the lighting fixture. In some examples, the ac parameters may include, but are not limited to, at least one of: current, voltage, power factor, electricity consumption, energy consumption collection, switching lamp status, dimming level, total lighting time, total operating time, leakage current, overvoltage, undervoltage, overcurrent information, and the like.

The angle detection module 107 is used for tilt angle detection. For a lighting fixture, the tilt angle means the degree to which the fixture is tipped. Taking a street lamp as an example, the inclination angle detected by the angle detection module 107 indicates the inclination angle of the lamp post, and is transmitted to the main control unit module 101. Optionally, the main control unit module 101 may accurately detect whether the lamp post is in a toppling dangerous state according to whether the inclination angle is greater than a preset threshold value, and perform on-site alarm; alternatively, the alarm may be selected by sending the inclination angle to an external calculation and returning a determination result of whether or not the alarm is in a dangerous state of toppling.

The at least one expansion communication module and the power supply output module 108 are used for connecting external equipment of the lighting lamp; the extended communication module is used for communication connection of external equipment, and the power supply output module 108 is used for power supply of the external equipment. For intelligent street lamps, various types of sensors need to be configured to collect environmental data. In some embodiments, an extended communication module corresponding to the sensor may be reserved. For example, in some embodiments, the at least one extended communication module includes: one or more of an I/O expansion module 109, a digital input module 110 (i.e., DI module), and a serial port communication module 111 (e.g., RS 485).

In some embodiments, the external device comprises an external active/passive switch or an extension sensor comprising at least one of: an environmental sensor; an illuminance sensor; a water immersion sensor. Illustratively, the environmental sensor may include, but is not limited to, at least one of a temperature and humidity sensor, a rain sensor, a wind speed and direction sensor, and the like, for example.

In some examples, the I/O expansion module 109 is configured to provide an input/output (I/O) port through which the main control unit module 101 exchanges information with the outside world.

In some examples, the digital input module 110 may be used for input of digital signals to a passive switch or an extension sensor. Illustratively, the digital input module 110 includes a first path digital input interface and a second path digital input interface. The first path of digital input interface provides passive dry contact input, and the second path of digital input interface provides water logging detection signal input.

In some examples, the power output module 108 provides a dc voltage output interface, such as 12V, for powering extension sensors, e.g., environmental sensors, illuminance sensors, etc. Illustratively, the output current capability of the DC voltage output interface reaches 400mA and can support over-current protection.

The modules are illustratively powered in combination with various dc power sources previously converted based on ac power. For example, cat.1 communication module is powered by 3.8V, HPLC communication module is powered by 3.3V, angle detection module 107 is powered by 3.3V, I/O expansion module 109 is powered by 3.3V, digital input module 110 is powered by 3.3V, serial port communication module 111 such as RS485 module is powered by 5V, metering module 106 is powered by 5V, lamp control unit module 102 is powered by 12V, and power output module 108 is powered by 12V. (Power supply output Module 108 is powered by 12V and 3.3V, providing a pull-up voltage)

As can be seen from the above, the lamp control unit module 102, the power module 103, the digital input module 110, the serial communication module 111, etc. provide some external interfaces. For example, referring to fig. 3, a schematic diagram of an interface panel of a single lamp controller in an embodiment of the present disclosure is shown.

In fig. 3, L, PE, N correspond to the live, ground, neutral terminals of an external AC power source AC. L1 and N1 are live wire and zero wire terminals of the lamp control unit module 102, which are respectively connected to live wire L and zero wire N ends of the first path of lighting unit, and output on/off signals of AC alternating current; l2 and N2 are live and neutral terminals of the lamp control unit module 102 connected to the live L and neutral N ends of the second lighting unit, respectively. A1 and A2 are terminals of the lamp control unit module 102 connected to the positive terminals of the dimming parts of the lighting unit 1 and the lighting unit 2, respectively, and the GND1 terminal of the positive terminals of the dimming parts of the lighting unit 1 and the lighting unit 2.

Also illustrated in fig. 3 are the RS485 interfaces of serial communication module 111, namely 485a+ and 485B-. Two connection terminals DI1 and DI2 and the GND2 terminal of the digital input module 110 are also exemplarily shown.

In some embodiments, the master unit module 101 may be implemented based on an embedded module. In a specific embodiment, the main control unit module 101 may select an ESP32-S2 series embedded module implementation, such as an ESP32-S2FH4 model, which is more suitable for the field of internet of things.

In some embodiments, the main control unit module 101 includes a timer with a preset duration. The main control unit module 101 outputs an instruction to the lamp control unit module 102 to set the at least one lighting unit to a preset lighting configuration for forming lighting in response to the communication module of the plurality of modes being disconnected from the target device for a preset time period. The application can be used for avoiding the situation that the communication disconnection of the lighting lamp is uncontrollable and ensuring the basic lighting function.

As shown in fig. 4, a schematic circuit diagram of the main control unit module 101 in an embodiment of the disclosure is schematically shown.

The single-chip microcomputer U1 of the main control unit module 101 is exemplified by 57 pins. Wherein, the No. 1 pin supplies 3.3V, and the No. 2 pin diameter antenna circuit is connected with the antenna ANT1. And the No. 5 pin is a GPIO port. The pin 6 is 595 to drive the clock terminal, and the pin 7 and the pin 8 are 595 to drive the IO high-order and low-order address terminal. 9. The 10 and 11 pins are the control, TX transmitting and RX receiving pins of the RS485 analog serial port. 12. The 42 pins are connected with RELAYs (RELAY 2 and RELAY 1) for connecting the lamp control switch module of the lamp control unit module 102 to control the two-way lighting unit switch. 13. The 14 pins are used for two paths DI1 and DI2 of the digital input module, respectively. The 15 pin outputs 12V voltage. 16. The pins 17, 18, 19 and 21 are used for connecting with the metering module 106, and the electrical parameter data is obtained for the two paths of lighting units '1' and '2'. The metering module 106 may be implemented, for example, as a multifunctional metering chip (EMU) with SPI, such as model ATT7053AU or ATT7053BU, etc. 22. The pins 23 and 24 are used for connecting with an HPLC communication module, controlling restarting, mutual data transceiving and the like. 40. The 41 pin connection angle detection module 107 is exemplified by an I2C protocol communication scheme. 43. The 44 pin is a PWM signal pin, PWM1 and PWM2, which controls the dimming control module of the lamp control unit module 102 to perform two-way dimming. 47. Pins 48 and 49 are used for connecting CAT.1 communication modules, controlling restarting, mutual data transceiving and the like, and can interact based on ISP communication protocols. The 50 pin is a watchdog pin. 52. 53 pin xtal_ N, XTAL _p is connected to the crystal oscillator clock. The 56 pin is a chip reset pin. The EP pin is grounded. 1. 51, 54, 3, 4, 20, 27, 30, 45 are power pins. When the 30 pin vdd_spi is in 3.3V mode, power is directly supplied by the 27 pin VDD3p3_rtc_io through about 5Ω resistor. Therefore, vdd_spi will have a certain voltage drop with respect to VDD3 p3_rtc_io.

It should be particularly noted that the above exemplary component models are merely illustrative of possible implementations, but not limiting of such implementations, and that additional alternatives are well within the skill of the art in light of the teachings of the present disclosure. Moreover, the present disclosure is directed to providing a structure of a single lamp controller for a lighting fixture capable of multimode communication, and does not involve software improvements.

As shown in fig. 5, a schematic structural diagram of a communication system based on a lighting fixture in an embodiment of the present disclosure is shown.

The communication system may include: a control platform 201, a centralized controller 202, and a single lamp controller 203 at each lighting fixture.

The centralized controller 202 is communicatively connected to the control platform 201 via a wireless connection mobile communication network. The mobile communication network may be, for example, a 4G/5G mobile operator network. The centralized controller 202 is further configured to be communicatively connected to each single-lamp controller 203, so as to centralize data of each lighting fixture and upload the data to the control platform 201, or distribute a control instruction of the control platform 201 to each single-lamp controller 203.

In some embodiments, each single-lamp controller 203 may be communicatively connected to the centralized controller 202 through a power line carrier communication module, and form a connection with the control platform 201 through a mobile communication connection between the centralized controller 202 and the control platform 201, so as to perform bidirectional interaction with the control platform 201, such as data uploading or instruction issuing of the lighting fixtures described above.

In addition, each single-lamp controller 203 may also be connected to the control platform 201 through the internet of things mobile communication module via a mobile communication network. When the communication from the power line carrier communication module to the control platform 201 is not smooth, for example, the power line carrier communication module fails or the centralized controller 202 fails, the communication between the mobile communication module of the internet of things and the control platform 201 can be switched.

Conversely, the communication between the mobile communication module and the power line carrier communication module can be switched from the mobile communication module of the internet to realize the redundancy application of the multi-mode communication mode by utilizing the single lamp controller 203, thereby improving the stability of the communication between the single lamp controller and the control platform 201.

In some embodiments, the internet of things mobile communication module and the power line carrier communication module are used in parallel, such as in parallel to perform transmission of different pieces of one data to the control platform 201 to achieve cooperation, or each to transmit different data to the control platform 201. One of the mobile communication module of the internet of things and the power line carrier communication module is responsible for sending the sending task of the data, the other is responsible for receiving the receiving task of the control instruction, and the like. The multi-mode communication task diversity application using the single lamp controller 203 is realized, and the communication efficiency is improved.

In some embodiments, the control platform 201 is communicatively coupled to a user terminal 204 to provide services regarding the lighting fixtures. For example, a user can realize remote lamp control application through a mobile phone APP.

In some embodiments, the lighting fixture may be a street lamp, preferably a smart street lamp having various circuit function modules (e.g., sensors, communicators, processors, etc.), and each of the lighting units may be a head of the street lamp, such as a street lamp having a double head or a single head.

In summary, in the embodiments of the disclosure, a single-lamp controller, a lighting fixture and a communication system are provided, where the single-lamp controller includes a main control unit module, a lamp control unit module, a communication module with multiple modes, and a power module; the power supply module is connected with an external power supply and is converted into an internal power supply for supplying power to other modules; the lamp control unit module is in communication connection with the main control unit module and is connected with at least one path of lighting units; the communication module of multiple modes includes: the power line carrier communication module and the Internet of things mobile communication module are connected with the main control unit module in a communication mode and are respectively used for wired and wireless bidirectional communication between the main control unit module and the outside.
