In this example, the micro IoT terminal itself is configured with dual network cards, one of which is connected to the gigabit switch using a network cable, the BTS timer is connected to the micro IoT terminal through a serial port or a USB port, and the control terminal uses a Any of PCs, laptops, tablets, and smartphones. The gigabit switch is connected to the lower LED sub-controller by using a network cable, and each LED sub-controller is connected in parallel. , are connected in a similar way, and the construction of a single lighting node in a building can be completed through a simple connection. In addition, the miniature Internet of Things terminal has the characteristics of small size, light weight, good compatibility, stable performance, strong scalability, and can mount multiple LED sub-controllers at the same time, which greatly enhances the number of dots and supports BTS base station timing. Packed with the server, and equipped with a 4G wireless communication module, the installation is not limited by space, and can be applied to a variety of complex environments.

Step S2 in this example includes the following sub-steps:

Step S201, firstly package the playback instruction received by the server into a JSON message block, and parse the JSON message block into a NodeNO field, where the value of the NodeNO field is the serial number of the weak current node and the content of the playback instruction, the weak current The node serial number is the serial number of the controlled weak current node obtained from the play instruction;

The JSON message block refers to the information block in the JavaScript Object Notation (JS Object Notation) format, the NodeNO field refers to the serial number of the weak current node, which is a naming method, and the value after NodeNo is the sequence of the weak current node. number, such as (NodeNo: 135795820), from which the node number is obtained. According to the node number, the node details stored in the database and the communication ip address are queried; the JSON format data block refers to the use of JavaScriptObject Notation (JS object mark) It is worth mentioning that step S2 in this example first wraps the playback instruction into a JSON message block, and then parses the NodeNo field in the JSON message block to obtain the serial number of the weak current node, and finally passes the weak current node serial number. The node serial number queries the local node IP address, stores the NodeNo field with the local node IP address, and writes the NodeNO field as a JSON format data block to obtain a data instruction packet. This optimized design makes the The application method of the architectural lighting control system based on the micro Internet of Things terminal can be distinguished from the existing technology, which can make the remote control and remote joint control more flexible and controllable, and the humanized design and reliability are effectively guaranteed. The optimized design adopted is different from the existing technology, and its anti-interference and safety performance are also very good.

More specifically, in the step S201, the parsing process of the NodeNO field is to obtain relevant data such as the serial number of the weak current node (NodeNo) by calling the server-side JSON data processing module and inputting JSON metadata.

In the step S202, querying the locally stored IP address of the corresponding node refers to querying by the node number (NodeNo), and the query statement uses the NodeNo number as the query condition to query the database, and it is obtained that the weak current node includes the IP address. all information. The process of adding the NodeNO field to the timing command and sending it in JSON format is as follows: the parsed JSON data is obtained from the start and end time periods of the playback timing, and then the start and end time periods of the playback timing are input to the server. The command converter then finds the target weak current node according to the obtained IP address, and sends the command through the operator network in JSON format.

In step S202 in this example, the server obtains the local IP address of the server through the IP address of the node, writes these NodeNO data into JSON format data blocks and sends them to the weak current node.

Therefore, the inventor combined the 4G router function with the Internet of Things terminal on the original basis, and installed a communication module without increasing its own volume and changing the shape, so that it does not require additional equipment to be plugged into the operator. The SIM card can communicate with the operator's network without occupying the resources of the main body, and the LED sub-control of the device itself can be used to control the load capacity.

The connection between the micro IoT terminal and the gigabit switch adopts the network port to the network port, and the network cable is used for connection, and the line sequence specification adopts 568B; The network cable with the line sequence of 568B is connected, and the connection diagram is shown in Figure 2. In this example, the server side adopts a server that receives the TCP/IP protocol, and the control terminal, the server side, and the micro IoT terminal use the TCP/IP communication protocol.

To sum up, this example realizes the intelligent, convenient, multi-compatibility and precise control of the modern architectural lighting system, and can realize remote control regulation and remote linkage control through the network, which is convenient to create a more perfect control effect, and The control application method and steps thereof are optimized, so that the micro Internet of Things terminal control application method is more flexible and controllable, and the humanized design and reliability performance are effectively guaranteed.
