Reason, and it is able to achieve monitoring and control of the monitoring computer to field device, realize the network savvy of valve industry Electric Actuator.
Detailed description of the invention
Fig. 1 is the principle schematic diagram of Electric Actuator networking TT&C system；
Fig. 2 is the structural principle block diagram of data transmission circuit.
Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
As shown in Figs. 1-2, the Electric Actuator networking TT&C system of the utility model includes:
Data transmission circuit, LoRa gateway, Cloud Server and monitoring computer, Cloud Server pass through LoRa gateway and data
Data transmission circuit, is transmitted the letter come by transmission circuit communication connection, the Cloud Server and monitoring computer communication connection
Number it is transmitted to monitoring Computer display.
Wherein, the data transmission circuit is located in field device, referring to attached drawing 2, includes voltage module 1, realizes number
According to the LoRa module 2 of wireless transmission, 433MHz antenna 3, the UART interface 4 that can be communicated with Electric Actuator.
The voltage module 1 is the voltage conversion circuit that direct current 5V turns direct current 3.3V, can give LoRa module for power supply, described
LoRa module 2 be Semtech company SX127x chip series of products, working frequency is in 433MHz, minimum quiescent current
It can reach 5uA, farthest transmission range reaches low-power consumption and transmit at a distance up to 3km, the 433MHz antenna of connection
3 be gain be 5dB, and the sucker antenna that impedance is 50 ohm, antenna should be placed on outside metal chassis.
Wherein, the UART of the UART interface 4 and Electric Actuator main control unit carries out serial communication, completes data and passes
It is defeated, and be connected with LoRa module 2.The UART interface 4 is connect with Electric Actuator master control borad, passes through the side of Transistor-Transistor Logic level
Formula is acquired and is interacted with the data that Electric Actuator master control borad completes equipment.
Wherein, the LoRa module uses star operating mode, and the connection of Electric Actuator can be realized by being equipped with LoRa gateway
Net function is communicated by LoRa gateway with Cloud Server, and monitors computer communication connection.
In the utility model, the LoRa gateway is the LoRa concentrator (gateway) of model USR-LG220, by outside
220V/50HZ AC power supply, is installed in Central Control Room；One gateway at most can 500 nodes of carry；The gateway uses MQTT
Agreement is sent data in cloud server, carries out message transmission using the form of publish/subscribe, cooperation LoRa module uses
The remote transmission of data is realized while greatly reducing transmission power consumption, the gateway is by the number of hundreds of equipment of child node
According to putting together, realize data in the upload of internet by way of connected with network cable.
