With the advancement of urbanization and the improvement of residents' living standard, elevator has become an indispensable vertical transportation tool in people's production and life. It is reported that China has become the world's largest elevator population. With the explosive growth of elevator application, the number of elevator accidents is still high, and the maintenance and maintenance of elevators are becoming more and more important. The causes of elevator accidents mainly include illegal operation, equipment defects and accidents. In order to effectively prevent the elevator accident, in addition to manufacturing enterprises optimization technology, maintenance organizations to strengthen the maintenance of the elevator, manufacturers can run through the Internet of things technology on elevator parameter monitoring, through data collection, timely feedback and data analysis, such as technology, to realize predictive diagnosis maintenance, will the elevator safety killed in the bud.
With the mature communication technology of the Internet of things, especially the application of nb-iot technology, the problem of signal coverage of all kinds of elevator shafts and cabs will be solved. The concept of "universal connection" of the Internet of things will play an important role in high-density elevator monitoring. The overall hardware and software solution of the Internet of things of smart com provides data acquisition hardware based on the communication network of operators. Through data interface and data acquisition address configuration, the collection and transmission of elevator operation parameters can be realized. Meanwhile, based on the mobile terminal information push, view management and other functions of the supporting Internet of things management software platform, as well as customized design and development capabilities, users can conduct centralized monitoring and management of multiple elevators.
1. Internet of things hardware development and integration design
Relying on the I/O expansion capability of Sprite IoT core board, Sprite can provide most elevator controllers with RS485 interface supporting Modbus protocol, so as to realize the collection of basic data of various elevators. In the application of narrow band, the intelligent terminal of Internet of things can collect the relevant control and operation parameters of elevators, and realize the collection and transmission of some picture functions, providing image reference support for elevator maintenance. In the aspect of broadband application, video acquisition technology can be integrated to realize the application of parameter + scene dual visual monitoring technology scheme. , moreover, the elves IoT solutions at the beginning of research and development personnel in the design takes into consideration the rising of Internet of things technology in the future (NB - IoT), as a result, this scheme can through subsequent replacement communication module and form a complete set of CARDS, to upgrade to the latest system smooth narrowband Internet of things, within the scope of further expansion of local access point and ensure the stable signals.
2. Internet of things management platform service
In order to maximize the efficiency and accuracy of daily elevator management and timely deal with alarm information, spritong, based on the API interface provided by Remote core hardware management service platform, helps users develop the Internet of things management enabling platform or related platform software, which can be deployed and managed by users according to their needs. The platform has a Rest API interface can meet the needs of different users call data, both to support the use of the elevator operational users and maintenance management, and can provide part of the interface for equipment manufacturing enterprises, is advantageous for the related enterprises to provide efficient after-sales service, so as to maximize the role of the Internet of the overall solution.
3. Customized service of traffic and tariff management
Smart connect Internet of things solutions are based on the operator network, reducing users' spending on local network construction and maintenance; Can achieve the terminal device plug and play, convenient and fast; At the same time, it can match the CARDS of different operators according to the requirements of users (real-name authentication is not required), and provide comprehensive service support such as traffic pool according to the needs of operation and maintenance, so that users can achieve the maximum efficiency at the minimum cost. Application scene design of elevator operation supervision
In order to facilitate user management, the software of infrastructure management service platform developed by spritong can chart the collected data and provide map GIS service, so as to more intuitively present the monitoring status and alarm information of elevators and realize more efficient management.
（(based on the basic configuration of the template communications and data address configuration, the system can be set according to the frequency and time to collect and upload the relevant information, and can through the data definition parsing of different brands, realize the regulation of elevator running parameters) < / p > < p > spirit through Internet software and hardware solutions for IoT core hardware based on strong and low power consumption, fully functional software system platform and customized design and development capabilities, can provide the Internet of things for existing equipment upgrading the overall solution, help achieve efficient monitoring elevators, Provide strong technical support of Internet of things for the long-term stable and safe operation of elevators.
