Description

Technical Field

[0001] The utility model relates to the field of street lamp control, and particularly relates to a street lamp control system based on dual-mode wireless communication of Wi-sun and Bluetooth. Background Technique

[0002] With the acceleration of the urbanization process, intelligent street lamp lighting, as an important part of a smart city, includes functions such as single-lamp energy-saving management system, remote detection, online management, automatic switching on and off of lights, and abnormal alarm. A single gateway needs to communicate with multiple single-lamp controllers, so high data rates and low latency are required to effectively control and detect the status of street lamps.

[0003] The current street lamp control system, such as a Bluetooth chain-shaped street lamp control system disclosed in CN105392255A, includes a chain-shaped street lamp unit and a gateway.

The street lamp includes a lamp, a street lamp driver for adjusting the brightness of the street lamp, a relay switch for controlling the on / off of the street lamp circuit, and a Bluetooth control component for controlling the operating state of the street lamp. The Bluetooth control component includes: an AC / DC conversion module, a microcontroller MCU, a BLE transceiver, and a photosensitive module. Data interaction is carried out between each street lamp through a wireless network formed by the BLE transceiver. However, in this solution, the communication between the gateway and the street lamp controller uses Bluetooth BLE, which uses a single-mode communication method. Bluetooth BLE 2.4GHz is easily interfered in a complex environment, affecting the transmission and easily causing the loss of transmitted data. Summary of the Utility Model

[0015] 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 with reference to the accompanying drawings in the embodiments of the present utility model.

[0016] The present utility model provides a street lamp control system based on Wi-sun and Bluetooth dual-mode wireless communication, including a gateway, a group of single lamp controllers, and LED lamps. The group of single lamp controllers includes multiple single lamp controllers, and each single lamp controller controls one LED lamp. The connection relationship between the gateway and the single lamp controllers is as Figure 1 shown.

[0017] Specifically, the gateway structure is as Figure 2 shown, and it includes a 4G_Cat1 module, an MCU processor, a Wi-sun module, a Bluetooth module, and an AC-DC (Alternating Current to Direct Current) power conversion module. The input end of the AC-DC power conversion module is connected to the commercial power, and the output end outputs a DC power supply and connects it to the power input ends of the 4G_Cat1 module, the MCU processor, the Wi-sun module, and the Bluetooth module to provide the power required for the operation of each module. The Wi-sun module and the Bluetooth module in the gateway are respectively wirelessly connected to the Wi-sun module and the Bluetooth module of the single lamp controller to realize the transmission of data and the transmission of control commands between the gateway and the single lamp controller. The 4G_Cat1 module communicates with the cloud IOT platform to realize the transmission of data and the transmission of control commands.

[0018] Specifically, the single lamp controller structure is as Figure 3As shown in the figure, it includes an MCU processor, a Wi-sun module, a Bluetooth module, a relay, a fuel gauge chip, and an AC-DC power conversion module. The input end of the AC-DC power conversion module is connected to the mains power, and the output end outputs a DC power supply, which is connected to the power input ends of the MCU processor, the Wi-sun module, the Bluetooth module, and the fuel gauge chip to provide the power required for the operation of each module and chip. After the fuel gauge chip obtains data such as voltage, current, active power, and reactive power values by connecting to the mains power that powers the LED, it transmits the data to the MCU processor. After receiving and processing the data from the fuel gauge chip, the MCU processor transmits the data to the Wi-sun module and the Bluetooth module. The MCU processor receives control instructions through the Wi-sun module and the Bluetooth module and sends them to the relay. After receiving the control instructions from the MCU processor, the relay performs the on / off light operation according to the instructions.

[0019] After receiving the data transmitted by the MCU processor, the Wi-sun module transmits the data to the Wi-sun module of the gateway and outputs the received control command to the MCU processor. After receiving the data transmitted by the MCU processor, the Bluetooth module transmits the data to the Bluetooth module of the gateway and outputs the received control command to the MCU processor.

[0020] Specifically, the gateway is installed within the wireless communication range of one or more single lamp controllers. The circuit structures in the multiple single lamp controllers are the same, and each single lamp controller controls one LED lamp. There are a 4G_Cat1 module, a Wi-sun module, and a Bluetooth module on the gateway group. The 4G_Cat1 module communicates with the cloud IOT platform to achieve data transmission and control command transmission. The Wi-sun module and the Bluetooth module of the gateway are respectively connected to the Wi-sun module and the Bluetooth module of the single lamp controller to achieve data transmission and control command transmission between the gateway group and the single lamp controller group.

[0021] Through the above solution, on the one hand, the Bluetooth 2.4GHz wireless communication method makes up for the problems of low data transmission rate and high latency in the Wi-sun 400-928MHz frequency band. On the other hand, the Bluetooth 2.4GHz plus Wi-sun 400-928MHz dual-mode communication method solves the problem that when one frequency band is interfered and data transmission and control command transmission cannot be achieved, there is still another frequency band that can achieve data transmission and control command transmission.

[0022] The above are only the preferred embodiments of the present utility model. It should be understood that the present utility model is not limited to the form disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the concept described herein through the above teachings or the techniques or knowledge in related fields.
