Intelligent Early Warning Platform Solution for a Central Court

I. Overview

The intelligent early warning platform of a Chinese hospital adopts the Internet of Things and information technology to collect monitoring data in real time and unify the summarized platform, which can carry out real-time monitoring and statistical collection point data. When the monitoring data reaches the threshold value, the platform will prompt in time for relevant personnel to deal with. The following describes the content and operation of the platform through three aspects: architecture, hardware and software.

II. Architecture

The platform system layer adopts the technology of front-end and back-end separation, in which the front-end uses responsive framework and the back-end uses microservice framework; the platform application layer adopts the BS architecture, accessing and using the platform functions through the browser; the platform IOT layer sensors and the gateway use RS485 communication, and the gateway and the network layer use RJ45 communication.

a) System mapping

The platform adopts the architecture of front-end and back-end separation, and the back-end is composed of micro-services in a way that supports distribution and ensures the scalability of the system. Asynchronous communication is used between services to ensure the timely response of the system. Logging and monitoring services ensure the high availability of the platform and improve the efficiency and quality of maintenance.

b) IOT topology map

The platform sensors all use RS485 devices, single or multiple sensor devices connected in series to access the gateway. The gateway is connected to a switch via RJ45 to interact with the platform.

c) Application of technical charts

The platform is deployed on two host instances, configured with system firewalls and application firewalls, and security parameters are configured for the host systems (configured according to system level protection 3). The data application will install the most recent stable version and install the latest patches. The collection and service program, developed with native code, ensures that the platform's code is scalable, and it can guarantee the security and confidentiality of the code. Application services are configured with dual nodes to ensure high platform availability.

III. Hardware

This phase of the project is planned for IoT modifications to the computer room, archive room and distribution boxes on each floor to monitor temperature, humidity, smoke alarms, flooding, UPS and electrical fires, respectively.

a) Equipment applications

✪ Flooding:

RS485 output, normally open contacts, monitoring objects for tap water, pure water.

Smoke Detectors.

RS485 output, smoke sensitivity 1.06±0.26%FT, alarm sound: ≥80dB.

Smart Micro Break:

RS485 output, poles 1P (no leakage protection), 2P, 3P, 4P, rated current: 10-80A, rated short-circuit capacity of 10,000A, monitoring functions are three-phase current, voltage, temperature, residual current, power consumption; protection functions are short-circuit, over-current, overload, over-temperature, over/under-voltage, leakage, arc faults, phase loss and three-phase unbalance.

b) List of products

_{Table 1}

c) Programmatic map

◆ 3rd floor computer room

The gateway is mounted on the wall to the left of the entrance door to the operator's room (reserved for network and mains power, the UPS gateway is combined in one box);
Flooding is installed at the most unfavorable point of the floor plan; temperature, humidity, and smoke sensors are staggered in the ceiling, and all sensors are connected in series using power and signal wires and brought into the gateway and accessed.

◆ 12th floor archives

The gateway is mounted on the wall of the entrance door (reserved for network and mains power);
Flooding is installed at the most unfavorable point of the floor plan; temperature, humidity, and smoke sensors are staggered in the ceiling, and all sensors are connected in series using power and signal wires and brought into the gateway and accessed.

◆ 2F Archives

The gateway is mounted on the wall of the entrance door (reserved for network and mains power);
Flooding is installed at the most unfavorable point of the floor plan; temperature, humidity, and smoke sensors are staggered in the ceiling, and all sensors are connected in series using power and signal wires and brought into the gateway and accessed.

◆ Power distribution box

The gateway is mounted on the rail next to the main switch (reserved for the network cable, mains power is taken from the distribution box);
Micro breaks that need to be upgraded can be directly replaced with intelligent micro breaks, using the RS485 communication line to access the gateway and upload the server.

d) Notes

The gateways are all connected to the intranet;
Gateway access to sensor devices can be expanded, the theory of each single-serial gateway can be accessed up to 254 devices (regardless of response time and construction cost premise);
Installation locations for temperature and humidity, smoke detection and flooding may be adjusted depending on actual conditions.

IV. Software

The platform consists of a visualization platform and a back-office management platform, an intranet environment, and access via a browser.

a) Functions

b) Role authority

^{Table 2}

^{Table 3}

All accounts on the platform need to be configured with a role for normal use. The role consists of a combination of project permissions (Table 2) and functional permissions (Table 3), in which the project permissions and functional permissions are gridded, and the project permissions and functional permissions can be customized and configured, and the platform will carry out independent verification to ensure the adaptability and security of the account permissions.

c) Notes

Platform features have been listed is based on the intranet environment of the standard features, such as personalized functional requirements, intranet environment can be achieved, the R & D team will evaluate the upgrade, the need for extranet support of the functional requirements, in addition to technical communication.
Role permissions can be communicated if there are special needs and added after technical evaluation.
