作者简介 刘凯，1995年毕业于上海大学（原名上海科技大学）电子工程系通讯工程专业。曾在NXP半导体（及前身飞利浦半导体）长期从事微电子应用设计与推广，主要职责为整体方案构建、固件与软件开发、市场营销等。在职期间，推动了Mifare RFID及LPC MCU在中国的普及和使用，同时在消费视频、移动通讯、可编程逻辑、汽车防盗等方面有过实际的产品设计经验。 2008年离职创业后，发明的RFID分类钱包获得授权，同时还设计过一些互联网服务。依托以往的从业和设计经验，目前主要为用户提供从芯片到云端的物联网系统集成和顾问咨询业务。主要工程有：电子货架标签，联网医疗设备，资产定位，蜂窝基站监控等。目前专注于LoRa的系统集成，以及房地产租赁相关的物联网系统集成。 作者长期关注开源设计，主张采用标准化组件、复用开源设计、减少开发语言等手段以实现快速开发，应对越发复杂的物联网需求。并在自己参与的物联网工程中，首选Python设计终端设备、网关、设备云、和应用服务系统。
About The Authors Li Liu kai, graduated from Shanghai university ( formerly Shanghai university of science and technology ) in 1995, majoring in communication engineering.Has been engaged in the design and promotion of microelectronics applications in nxp semiconductors ( and formerly Philips semiconductor ), the main responsibility for the overall scheme construction, firmware and software development, marketing and so on.During the service period, the mifare RFID and LPC MCU are promoted and used in China, at the same time, there are practical product design experience in consumer video, mobile communication, programmable logic, automobile anti-theft and so on. After the departure of the business in 2008, the invention of RFID classified wallet was authorized, and also designed some internet services.Relying on the past practice and design experience, the internet of things system integration and consultancy business from the chip to the cloud is mainly provided for the users.The main projects are: electronic shelf label, network medical equipment, asset location, cellular base station monitoring and so on.Currently focused on the lora system integration, and the real estate leasing related internet of things system integration. The author has long paid attention to open source design, advocated the use of standardized components, reuse open source design, reduce development language and other means to achieve rapid development to meet the more complex internet of things demand.And in its own participation in the internet of things engineering, preferred python design terminal equipment, gateway, equipment cloud, and application service system.
Introduction of the author Liu, 1995 graduated from Shanghai University (formerly known as Shanghai University of Science and Technology) Electronic Engineering department Communications engineering Major. NXP Semiconductor (and predecessor Philips Semiconductor) has long been engaged in microelectronics application design and promotion, the main responsibility for the overall program construction, firmware and software development, marketing and so on. During the service, the promotion of Mifare RFID and LPC MCU in China's popularization and use, at the same time in consumer video, mobile communications, programmable logic, car anti-theft and other aspects of the actual product design experience. After leaving business in 2008, the invention of the RFID classification wallet was authorized and some Internet services were designed. Based on previous experience in practice and design, the company provides users with the integration of Internet systems and consulting services from Chip to cloud. The main projects are: electronic shelf labels, networking medical equipment, asset positioning, cellular base station monitoring. Currently focused on Lora system integration, as well as real estate leasing-related IoT system integration. The author has long paid attention to open source design, advocated the adoption of standardized components, reuse of open source design, reduce the development of language and other means to achieve rapid development, to meet the increasingly complex needs of the internet of things. And in the network of things they participate in, the preferred Python design terminals, gateways, equipment cloud, and application services system.
