Time-sensitive network communication system and method based on SiPM sensor

Abstract

The invention discloses a time-sensitive network communication system and method based on a SiPM sensor. The SiPM sensor and a data acquisition module are arranged as front-end acquisition equipment to receive information data of a scintillation pulse event, an FPGA main controller analyzes and operates the data, packages the data into UDP data, converts the UDP data into optical signals through an Ethernet PHY chip and a front-end SFP optical transceiver module, and sends the optical signals, a receiving end receives the optical signals and exchanges data with a server through a PCIE interface, the receiving and transmission rate of the receiving end can reach 4.00 Gbps, the sending rate of the receiving end is 3.85 Gbps, and large-data-volume information exchange can be provided. Based on the TSN specification, the real-time performance and stability of data can be ensured in information communication; and meanwhile, independent protocol standards are adopted for all protocols, goodcompatibility is achieved, and convenience is provided for later expansion and interconnection and intercommunication with other devices.

Description

technical field [0001] The invention relates to the field of photon imaging and optical communication, in particular to a time-sensitive network communication system and method based on SiPM sensors. Background technique [0002] SiPM (Silicon Photomultiplier, that is, silicon photomultiplier, hereinafter referred to as SiPM) is widely used in high-energy physics and nuclear medicine and other fields. Compared with traditional photoelectric conversion devices, such as photomultiplier tubes and avalanche photomultiplier tubes, SiPM has small dimensions, low power supply voltage, high gain, and is not easily affected by magnetic fields. As a digital photoelectric conversion device, SiPM can be A digital detector module with excellent performance and compact form factor is realized at a lower cost.

AI Technical Summary

Problems solved by technology

[0003] Universal Ethernet is currently the most widely used communication protocol, but Universal Ethernet communicates data in an asynchronous manner, while SiPM sensors need to send data at any time. Traditional Ethernet uses a random backoff mechanism to avoid conflicts, resulting in data transmission The accuracy and real-time performance of the

Therefore, when a large number of SiPM sensors collect data at the same time, large-scale data will increase the network load, resulting in greater delay or even network crash.
