Modular RTU PetroChina RTU

Ethernetwirelessintelligent

Intelligent terminal devices customized for the traditional oil pumping unit of PetroChina. It can communicate with intelligent sensors through RS485 bus, and communicate with sensors such as load, displacement, pressure, etc. in wellhead through zigbee or wired mode. It can complete the acquisition of dynamometer graph through load integration, load + angular displacement and other modes. The collected data is uploaded to the SCADA system via the Ethernet MODBUS TCP protocol. Wellsite CPU401-1201 >>> CPU frequency 300MHz, memory 64M, 128M FLASH storage, SD card support. The internal integrated clock also supports NTP time adjustment. Integrated Ethernet interface, can be directly connected with SCADA, in line with Changqing RTU point table standard. Support remote configuration of thinning function. Support remote firmware upgrade in Ethernet mode. ZigBee communication module is external, which is convenient to support multiple wireless methods. The AI input channel hardware has short circuit protection. Support protocol converter access between valve groups. Wellhead CPU401-1202 >>> CPU frequency is 168MHz, integrated 8M serial FLASH storage. The internal integrated clock also supports NTP time adjustment. Integrated Ethernet interface, can be directly connected with SCADA, in line with Changqing RTU point table standard. Support the function of pumping. Support remote firmware upgrade in Ethernet mode. ZigBee communication module is external, which is convenient to support multiple wireless methods.
