Dedicated multi-channel intelligent gateway for industrial metering pump set cluster remote monitoring

Abstract

The invention discloses a dedicated multi-channel intelligent gateway for industrial metering pump set cluster remote monitoring. The intelligent gateway is composed of an ARM microcontroller, a periphery circuit, a CAN communication module, an Ethernet communication module, and a 4G communication module, and used for realizing two-way data passthrough communication among a remote PC work station,a mobile phone side and a detected digital frequency-variable controller for the metering pump, and realizing the stable remote networked monitoring on the industrial metering pump set cluster system. The communication quality and the network stability can be maximally guaranteed through a multichannel redundancy communication scheme and a communication abnormal emergency mechanism. The effectiveness and the instantaneity of the communication and the control are satisfied by adopting an advanced underlying network priority policy and a scheduling algorithm and an upper layer network efficientblocking technology. And meanwhile, the working efficiency of the metering pump set can be maximally guaranteed by adopting an effective underlying network node management mechanism, and the loss onthe production quality caused by the offline of individual node is avoided.

Description

technical field [0001] The present invention is applied to the field of remote monitoring and communication of industrial metering pump group clusters to realize the networking and remote monitoring of the pump group cluster system, which involves real-time and security in the networking and communication process, especially the multi-channel redundancy scheme Realize the monitoring requirements for metering pump group cluster systems in various industrial environments and complex geographical environments. Background technique [0002] In most chemical and pharmaceutical fields, a large amount of corrosive fluid is required as processing raw material for processing, and high dosing accuracy is required. Metering pumps, as a kind of special pumps that not only meet the anti-corrosion requirements, but also meet the needs of various strict technological processes, are widely used in various industrial fields such as petrochemical, pharmaceutical, environmental protection and ...

Problems solved by technology

[0007] At the same time, when the communication network of the metering pump cluster system communicates in the upper industrial Ethernet Ethernet and 4G wireless network, because the data frames transmitted on the underlying CAN bus network are in short frame format, uploading without processing will cause a large number of data frames in the upper network. Short packets cause the bandwidth utilization rate of the upper network to drop rapidly, and the data packet congestion and collision probability increase

For this kind of problem, Nagle algorithm can be used to solve it, but it needs to pay the price of occupying a large amount of computing resources of ARM, which will affect the real-time communication of the gateway.
