物联网压力变送器的发展趋势
如果说单晶硅技术压力变送器是国产流程工业型压力变送器的代表，那么“物联网压力变送器”、“智能互联压力变送器”、“压力变送器4.0”、“人工智能压力变送器”等相关智能、互联和物联类型的压力变送器是下一代压力变送器的代名词。下一代压力变送器相比单晶硅压力变送器，除了常规的性能精度更高、稳定性更好，核心的区别在于解决现在压力变送器的“痛点”：通过“互联或物联”实现“在线自校准”、“在线自清零”、“预测性维护和维修”等智能功能，并帮助压力变送器生产厂商实现从压力变送器的产品生产销售到提供压力测量服务的角色转变，这才是压力变送器实现升级换代的意义。
If single crystal silicon technology pressure transmitter is the representative of domestic process industrial pressure transmitter, then the next generation of pressure transmitter is related intelligence, interconnection and material connection, such as "Internet of Things pressure transmitter", "intelligent interconnection pressure transmitter", "pressure transmitter 4.0", "artificial intelligence pressure transmitter". The pronoun of force transmitter. Compared with single crystal silicon pressure transmitter, the next generation pressure transmitter has higher accuracy and better stability. The key difference lies in solving the pain point of the current pressure transmitter: realizing the intelligence of "online self-calibration", "online self-clearing", "predictive maintenance and maintenance" through "interconnection or material connection". Function, and help pressure transmitter manufacturers to achieve the role change from production and sales of pressure transmitter products to providing pressure measurement services, which is the significance of pressure transmitter upgrading.
在我们看来，物联网分为民用物联网和工业物联网两大部分，民用物联网就是大家经常说的物联网，包括智能家居、智能物联、智能交通、智能安防、智能电力、智能医疗等，它们与大家的生活密切相关，自然而然成为大家关注的焦点。还有就是这两年大家谈论比较多的工业物联网，随着国内外各大品牌的工业操作系统（基于云的开放式IoT操作系统（PaaS））的密集推出，更确切的说是流程工业物联网的快速发展，让原来少为人知的大型石油化工工厂借助工业物联网朝着安全、环保、节能的智能制造方向升级。
In our view, the Internet of Things is divided into two parts: the Civil Internet of Things and the Industrial Internet of Things. Civil Internet of Things is what we often call the Internet of Things, including smart home, smart Internet of Things, smart transportation, smart security, smart power, smart medical care and so on. They are closely related to everybody's life and naturally become a gateway for everyone. Focus of attention. In addition, in the past two years, people have talked more about the industrial Internet of Things. With the intensive introduction of the major brands of industrial operating systems (PaaS) at home and abroad, more precisely, the rapid development of the Internet of Things in the process industry has enabled the previously little-known large petrochemical plants to rely on industry. The Internet of Things has been upgraded to the direction of intelligent manufacturing with safety, environmental protection and energy saving.
随着《物联网压力变送器规范》——GBT34073-2017于2018年2月1日正式实施，物联网压力变送器诞生。物联网压力变送器具有特殊的物联网特性要求：包括识别性要求，压力变送器应具有可识别的身份标识；可操作性要求，压力变送器应具有可操作性；可信性要求，压力变送器诊断机制、误操作侦测、报警等要具有可信性；网络安全性，压力变送器应满足所在物联网的安全性要求，如不同等级的访问权限等；以及数据及文档结构。目前流程工业用户对压力变送器精度要求是0.075%，该规范规定了0.02%、0.05%、0.1%、0.2%、0.5%、1%、1.5%共7个准确度等级，在我们看来，从0.2%到1.5%这4个比较低的准确度等级更多用于民用物联网，而0.02%、0.05%、0.1%这3个准确度等级可以用于流程工业物联网，而大规模的工业物联网应用可能是以0.02%的为主，或者说只有压力变送器达到了0.02%准确度等级才能真正发挥流程工业物联网压力变送器使用价值。
With the implementation of "Internet of Things Pressure Transmitter Specification" - GBT34073-2017 on February 1, 2018, the Internet of Things Pressure Transmitter was born. Internet of Things pressure transmitter has special characteristics of Internet of Things: including identification requirements, pressure transmitter should have identifiable identity; operability requirements, pressure transmitter should be operable; credibility requirements, pressure transmitter diagnosis mechanism, misoperation detection, alarm and so on should be credible; Network security, pressure transmitter should meet the security requirements of the Internet of Things, such as different levels of access rights, and data and document structure. At present, the accuracy requirement of pressure transmitter for process industry users is 0.075%. The specifications stipulate 7 accuracy levels: 0.02%, 0.05%, 0.1%, 0.2%, 0.5%, 1% and 1.5%. In our opinion, from 0.2% to 1.5%, the four lower accuracy levels are more used in civil Internet of Things, while the three accuracy levels of 0.02%, 0.05% and 0.1% are acceptable. For the process industry Internet of Things, the large-scale industrial Internet of Things applications may be mainly 0.02%, or only when the pressure transmitter reaches the accuracy level of 0.02%, can the pressure transmitter of the process industry Internet of Things really play its use value.
高精度稳定性是常规压力变送器的核心性能，另一方面特殊的行业用户对压力变送器的要求却不仅仅这些，比如制药行业的用户，除了要求压力变送器的精度优于0.2%，卫生无菌也是核心的要求。智能制药的智能药品包装生产线及设备更少更集中，相比大型化工工厂的智能化可能会更早落地实现。压力变送器厂商遵照FDA、EMA、CFDA等不同版本的GMP规范进行探讨，如何确保压力变送器在药品生产过程中卫生无菌、避免交叉污染和生产过程更高效等，特别是与药品或中间体、原料接触的测量膜片的材料、工艺方面，一些厂商推出了适合CIP/SIP温度瞬变冲击测量膜片，也有厂商推出耐过程流体冲击的膜片，还有带监控功能的双膜片，在一个批次的药品生产中，即使一个膜片破损依然可以正常进行卫生无菌测量，不会污染药品，并且输出报警提醒现场操作员在完成批次生产后更换压力变送器。相比大型工厂，用于制药包装生产线的压力变送器分布在小范围内，并且数量不多，测量膜片、内部电子元件等状态的监控的采集、上传和分析相对容易。诸多因素考虑，下一代压力变送器可能率先在制药行业取得突破。
High precision stability is the core performance of conventional pressure transmitters. On the other hand, special industry users require more than these pressure transmitters. For example, users in pharmaceutical industry, besides the requirement that the accuracy of pressure transmitters is better than 0.2%, hygiene and sterility are also the core requirements. Intelligent pharmaceutical packaging production lines and equipment are fewer and more centralized, which may be realized earlier than the intellectualization of large chemical plants. Pressure transmitter manufacturers follow the GMP specifications of FDA, EMA, CFDA and other versions to discuss how to ensure that pressure transmitters are hygienic and sterile in the pharmaceutical production process, avoid cross-contamination and more efficient in the production process, especially in the material and process of measuring diaphragms in contact with drugs or intermediates and raw materials. The diaphragm suitable for CIP/SIP temperature transient impact measurement was introduced, and some manufacturers introduced diaphragms resistant to process fluid impact, as well as double diaphragms with monitoring function. In a batch of pharmaceutical production, even if a diaphragm is damaged, it can still carry out hygienic aseptic measurement normally without contaminating drugs, and output alarms to remind the scene. The operator replaces the pressure transmitter after completing batch production. Compared with large-scale factories, pressure transmitters used in pharmaceutical packaging production line are distributed in a small range, and the number is small. It is relatively easy to collect, upload and analyze the monitoring of diaphragm and internal electronic components. Considering many factors, the next generation of pressure transmitters may take the lead in making breakthroughs in the pharmaceutical industry.
