Embodiment 1

[0029] The working principle of a ZigBee-based Internet of Things data collection terminal is as follows: the sensor metering module 101 collects electric energy data in smart sockets and smart meters, and transmits the data to the ZigBee communication module 104 through RS485 / 232 wired communication. After the ZigBee communication module 104 receives the power data information sent by the sensor metering module 101, it first performs protocol conversion 202, and converts it into a unified communication protocol object according to the MQTT-SN protocol; then, the power data information is converted into an object according to the Modbus standard Serialization 203; finally, data transmission 204 is realized through the Zigbee wireless network. The electric energy data received by the ZigBee communication module 104 is stored in the FLASH storage module 102 . The power management module 103 establishes an electrical connection with the ZigBee communication module 104 to realize ...

Abstract

The invention discloses an Internet of things data acquisition terminal based on ZigBee, comprising a sensing measurement module, a ZigBee communication module, a FLASH storage module, a power management module, a button and an indicator lamp, wherein the sensing measurement module is in wired communication connection with the ZigBee communication module, and the ZigBee communication module is electrically connected with the FLASH storage module, the power management module, the button and the indicator lamp; the ZigBee communication module firstly performs protocol conversion after receiving the data information sent by the sensing measurement module, and converts the data information to a unified communication protocol object such as an MQTT-SN protocol; and then, the data information is serialized according to a certain standard such as a Modbus standard, a Cbor standard and the like; and finally, the data is transmitted through a ZigBee wireless network.

Description

technical field [0001] The invention relates to a ZigBee-based Internet of Things data acquisition terminal, belonging to the technical field of the Internet of Things. Background technique [0002] With the rapid development of sensing technology, identification technology, information communication technology and the Internet, the Internet of Things has achieved rapid development and wide application. According to the definition of the International Telecommunication Union (ITU), the Internet of Things is information sensing equipment such as two-dimensional code reading equipment, radio frequency identification (RFID) devices, infrared sensors, global positioning systems and laser scanners, according to the agreed protocol, A network that connects any item to the Internet for information exchange and communication to realize intelligent identification, positioning, tracking, monitoring and management. The Internet of Things will be the next "important productivity" to pr...
