Abstract
Description
Technical Field
[0001] This invention relates to the field of street lighting communication technology, and in particular to a smart street light management method and system that integrates multiple protocols. Background Technology
[0002] In the process of city-level street light energy-saving renovation projects, due to phased construction, the communication schemes and suppliers of the unrenovated and renovated street lights, as well as the previously renovated and newly renovated street lights, are different. It is difficult to unify the street light communication protocol for the entire city. Therefore, a city often has multiple street light management systems operating in parallel, which undoubtedly increases the difficulty of street light management and brings inconvenience to street light management.
[0003] Therefore, there is a need to provide a street light management method and system that is compatible with street light controllers or centralized controllers with different communication schemes and protocols, so as to achieve the goal of unified management of street lights under the current situation of multi-protocol communication. Summary of the Invention
[0004] The main objective of this invention is to overcome the above-mentioned shortcomings and deficiencies of the prior art and to provide a smart street light management method and system that integrates multiple protocols.
[0005] A multi-protocol integrated smart street light management method includes the following steps:
[0006] Step 1: Connect street light controllers with different communication protocols to the data receiving and processing platform;
[0007] Step 2: After the data reported by the street light controller arrives at the data receiving and processing platform, the data receiving and processing platform distinguishes the types of street light controllers according to the reporting topic;
[0008] Step 3: The data receiving and processing platform converts various communication protocols into a unified protocol format and uses the unified format to store the reported data from various street light controllers;
[0009] Step 4: When the data that needs to be sent to the street light controller arrives at the data receiving and processing platform, the data receiving and processing platform distinguishes the types of street light controllers according to the sending topic, and parses and processes the unified format protocol data into different protocols of the street light controller.
[0010] Step 5: After processing the data protocol, send the data to the street light controller through different communication protocols.
[0011] In one embodiment, step 2 specifically includes, based on the reporting topic, the following:
[0012] Street light controllers using the MQTT communication protocol can be distinguished by MQTT topics;
[0013] Street light controllers using the TCP communication protocol transmit data to the MQTT Broker via the TCP server, and different street light controllers are distinguished by the topics of the transmitted MQTT messages.
[0014] Street light controllers using the NBIOT communication protocol can be distinguished through push APIs.
[0015] In one embodiment, the data receiving and processing platform includes a connection unit, a data processing unit, and a storage unit. The connection unit establishes an MQTT connection with the street light controller based on the MQTT connection request issued by the street light controller, and sends a confirmation command to the street light controller to establish the connection.
[0016] The street light controller sends a subscription topic request through the connection unit, and the data processing unit sends a subscription confirmation instruction back to the street light controller through the connection unit.
[0017] The data processing unit groups the street light controllers that request different topics, and the storage unit will be used to store the group information.
[0018] In one embodiment, the street light controller using the TCP communication protocol sends an MQTT connection request. First, the MQTT connection request is reported to the TCP server. The TCP server then forwards the connection request to the MQTT Broker via the MQTT scheme. Finally, the MQTT Broker sends the connection request to the connection unit.
[0019] In one embodiment, step 3 includes:
[0020] Step 3.1: After receiving the reported data, the data receiving and processing platform analyzes the MQTT topic;
[0021] Step 3.2: Locate a dedicated protocol parsing library to save the data as a JSON string in a uniform format;
[0022] Step 3.3: After parsing the JSON string, process and store the data.
[0023] In one embodiment, step 4 includes:
[0024] Step 4.1: After receiving the data, the data receiving and processing platform finds the common JSON string that makes up the data.
[0025] Step 4.2: Analyze the MQTT topic and find a dedicated protocol parsing library to generate a JSON string in a unified format;
[0026] Step 4.3: Perform reverse parsing to obtain the corresponding reverse parsing protocol;
[0027] Step 4.4: Send the data to different street light controllers using different protocols.
[0028] In one embodiment, the step of sending data to different street light controllers via different protocols specifically includes:
[0029] For street light controllers that use TCP and MQTT communication protocols, data is forwarded through an MQTT Broker.
[0030] Street light controllers using the MQTT communication protocol send data directly from the MQTT Broker. Street light controllers using the TCP protocol have the MQTT Broker first pass the data through to the TCP server, and then the TCP server sends the data to the street light controller.
[0031] Street light controllers using the NBIOT communication protocol can send data directly to the street light controller via the API.
[0032] A multi-protocol integrated smart street light management system includes a data receiving and processing platform connected to street light controllers with different communication protocols. The data receiving and processing platform distinguishes the types of street light controllers based on the reporting topic. The platform uniformly converts various communication protocols into a unified protocol format and stores the reported data from various street light controllers using this unified format. When data to be sent to a street light controller arrives at the data receiving and processing platform, the platform distinguishes the types of street light controllers based on the reporting topic and parses the unified format protocol data into different protocols for each street light controller. After processing the data protocols, the platform then sends the data to the street light controllers through the different communication protocols.
[0033] In one embodiment, the data receiving and processing platform includes a connection unit, a data processing unit, and a storage unit. The connection unit establishes an MQTT connection with the street light controller based on the MQTT connection request issued by the street light controller and sends a confirmation command to the street light controller. The street light controller sends a subscription topic request through the connection unit, and the data processing unit sends a subscription confirmation command to the street light controller through the connection unit. The data processing unit groups the street light controllers with different topic requests, and the storage unit stores the grouping information.
[0034] The beneficial effects of this invention are that it can be compatible with street light controllers or centralized controllers with different communication schemes and protocols, realizing unified management of street lights under the current situation of multi-protocol communication, and reducing the difficulty of street light management.

[0053] Example 1
[0054] Please see Figure 1 and Figure 2 This invention provides a smart street light management method that integrates multiple protocols, comprising the following steps:
[0055] Step S01: Connect the street light controllers 200 with different communication protocols to the data receiving and processing platform 100;
[0056] Step S02: After the reported data from the street light controller 200 arrives at the data receiving and processing platform 100, the data receiving and processing platform 100 distinguishes the types of street light controllers 200 according to the reporting topic.
[0057] Step S03: The data receiving and processing platform 100 converts various communication protocols into a unified protocol format and uses the unified format to store the reported data of various street light controllers 200.
[0058] Step S04: When the data that needs to be sent to the street light controller 200 arrives at the data receiving and processing platform 100, the data receiving and processing platform 100 distinguishes the types of street light controllers 200 according to the sending topic, and parses and processes the unified format protocol data into different protocols of the street light controllers 200.
[0059] Step S05: After processing the data protocol, send the data to the street light controller 200 through different communication protocols.
[0060] Please refer to Figure 2 Street light controllers 200 can be divided into two categories based on whether a centralized controller is required: one category requires a centralized control gateway, such as PLC, Zigbee, and LoRa; the other category communicates with a cloud platform through a commercial base station, such as CAT.1 and NB-IoT. Street light controllers 200 can also be divided into three categories based on their communication protocol: MQTT, TCP, and push notifications from a carrier connection platform.
[0061] For more details, please refer to Figure 2 Step 2, based on the reported topic, specifically includes:
[0062] The street light controller 200 uses the MQTT communication protocol and distinguishes different street light controllers 200 through MQTT topics;
[0063] The street light controller 200, which uses the TCP communication protocol, transmits data to the MQTT Broker through the TCP server. Different street light controllers 200 are distinguished by the topic of the transmitted MQTT.
[0064] The street light controller 200, which uses the NBIOT communication protocol, is distinguished by the push API.
[0065] In this process, the street light controller 200, which uses the TCP communication protocol, reports data to the TCP server. The TCP server then transmits the data to the MQTT Broker via the MQTT protocol. The advantage of this is that all data will be sent to the data receiving and processing platform 100 by the MQTT broker in a centralized manner, eliminating the need to maintain a separate connection with the TCP server. This allows all data to be finally aggregated and processed on the data receiving and processing platform 100.
[0066] For more details, please refer to Figure 3 The data receiving and processing platform 100 includes a connection unit 101, a data processing unit 102, and a storage unit 103. The connection unit 101 establishes an MQTT connection with the street light controller 200 based on the MQTT connection request issued by the street light controller 200, and sends a confirmation command to the street light controller 200 to confirm the connection establishment.
[0067] The street light controller 200 sends a subscription topic request through the connection unit 101, and the data processing unit 102 sends a subscription confirmation instruction back to the street light controller 200 through the connection unit 101.
[0068] The data processing unit 102 groups the street light controllers 200 that request different topics, and the storage unit 103 uses the grouping information to store the information.
[0069] More specifically, the street light controller 200, which uses the TCP communication protocol, sends an MQTT connection request. First, the MQTT connection request is reported to the TCP server. The TCP server then forwards the connection request to the MQTTBroker via the MQTT scheme. Finally, the MQTT Broker sends the connection request to the connection unit.

[0082] Step 4.2: Analyze the MQTT topic and find a dedicated protocol parsing library to generate a JSON string in a unified format;
[0083] Step 4.3: Perform reverse parsing to obtain the corresponding reverse parsing protocol;
[0084] Step 4.4: Send the data to different street light controllers 200 using different protocols.
[0085] For more details, please refer to Figure 6 Data is sent to different street light controllers 200 via different protocols, specifically including:
[0086] For the street light controller 200 that uses TCP and MQTT communication protocols, the data is forwarded through the MQTT Broker.
[0087] Street light controller 200 using the MQTT communication protocol sends data directly from the MQTT Broker. Street light controller 200 using the TCP protocol has the MQTT Broker first pass the data through to the TCP server, and then the TCP server sends the data to the street light controller 200.

After processing the data protocols, the data is then sent to the street light controllers 200 through different communication protocols.
[0091] The data receiving and processing platform 100 includes a connection unit 101, a data processing unit 102, and a storage unit 103. The connection unit 101 establishes an MQTT connection with the street light controller 200 based on the MQTT connection request issued by the street light controller 200, and sends a confirmation command to the street light controller 200 to confirm the connection. The street light controller 200 sends a subscription topic request through the connection unit 101, and the data processing unit 102 sends a subscription confirmation command to the street light controller 200 through the connection unit 101.
