The Smart Parking Internet of Things (IoT) solution provides an application-oriented platform that combines hardware and software for automated parking facilities, helping system integrators to quickly and efficiently deploy IoT/Cloud applications without updating existing devices. Through the IoT gateway to continuously upload data to the cloud, the central control staff can simultaneously and instantly monitor the operation status of multiple parking facilities remotely. Through big data collection and analysis, it is also possible to predict and detect system anomalies at an earlier stage. Preventive measures can be implemented before the problem worsens. It can minimize the risk of system failure and reduce the number of on-site inspections and overhauls, greatly improving system maintenance efficiency while reducing maintenance and operating costs.
