WARNING AND MONITORING SYSTEM ABOUT TEMPERATURE AND HUMIDITY COMMUNICATED INTELLIGENT WIRELESS NETWORK

1. Introduction:

After surveying works like installation of temperature alarm monitoring for hospitals such as the  Tropical Hospital , Cho Ray Hospital and Children's Hospital Number 1, one of the difficulties is to have to spend expensive costs for connecting  signal wires between the sensors, temperature probes with center monitoring  control cabinet.

Due to the amount of the temperature probes are distributed in many different rooms and several floors of the hospital, wiring and tubing is genetically complex and time consuming. The wiring must be assured of a smooth signal transmission while not missing beauty with many different types of wires of the hospital like submersible wiring in the wall, sunk in the ceiling,  floating wiring,  underground wiring. This will cost for surveying the space survey prior to making estimates. With signal wiring so synonymous with the refrigerator must be fixed and the replacement or addition of a new refrigerator is hard work.

2. Solve the problems:

ECAPRO studied and launched a new solution for these problems is "warning and monitoring system of temperature and humidity through the intelligent wireless network communications"


This system has gained a lot of advantages:

The system was installed quickly, easily, with different spaces without previous survey. Things that reduce construction time laying down 1/5 wire systems use signals.

The device uses battery power for 1 year with energy saving technology nanoWatt.

The probes have high mobility, can more or less easily and can be installed in the device moves.

Each thermal probe Ministry wireless communications have two temperature sensors allow for 2 refrigerator installation in close proximity.

Use multi-purpose with the type refrigerator containing medication, refrigerators containing vaccines, blood contained refrigerator, refrigerator containing food, cold storage and server rooms.

TEMPERASPECIFIC SOLUTION OF MANAGEMENT FOR DRUG AND BLOOD STORING REFRIGERATOR IN HOSPITAL.TURE MONITORING AND SUPERVISION SOLUTION FOR THE REFRIGERATOR AND COLD STORAGES WHERE IT NEEDS TO MANAGE INVIRONMENTAL TEMPERATURE

SPECIFIC SOLUTION OF MANAGEMENT FOR DRUG AND BLOOD STORING REFRIGERATOR IN HOSPITAL.

1. Requires for temperature supervising solution.

The requirements content of temperature monitoring solution for pharmaceutical and blood storage refrigerators.

 Objective of solutions:

Monitoring the temperature for the refrigerator to preserve blood and pharmaceuticals.

Temperature range to be measured: from -50 oC to + 10oC.

Number of refrigerator: 20 cabinets

The location of the refrigerator: not fixed, are located in different rooms in the hospital.

Description: Monitoring for cold storage, when the temperature exceeds the temperature range allows the alarm using the following methods: the light is on when temperature sensor identify that the temperature  exceed in the central cabinet, send SMS manages phone number and and display information in real time on the web server. In case, the 220VAC power failure, immediately alerts via SMS, to take timely treatment. In this case the equipment is built 1 system of UPS12V  for using when the power failure, so the system can work more within 12 hours.

 

2. Proposal for temperature monitoring solution

2.1. Model of system

The system model  consists of three main components:

1. The temperature probe connected Modbus RTU

2. Temperature Monitoring Center (Server)

3. Computers observed LAN connection (Client)

The temperature probe placed in the refrigerator with a temperature range from -50 to 85 degrees C with a tolerance of ± 0.1 ° C. The probe uses RS485 network connection allows placed in different positions with a maximum distance to 1000m to temperature monitoring center.

Each temperature monitoring center can handle 10 temperature probes. Temperature monitoring center will receive data obtained from the temperature probe, data storage (data storage to 4GB), processing and issuing warnings directly through light, through SMS and supervised directly by the web server. Centre monitoring LAN connectivity and embedded web and IP addresses, so there are a lot of central cabinet and all can be connected to the LAN. As the need to monitor any  cabinet, just need to enter that cabinet ‘s IP in LAN. 

The computers in the local network (LAN) that can monitor the central cabinet through IP or hostname . These parameters are displayed on the machine, the need to change the parameters should have access Password and Username.

 

 2.2 Temperature Monitoring Center ECA-GPIs4.4ETHL

SCADA SYSTEM WITH WEB SERVER

 

We would like to introduce HMI SCADA system with a web server. SCADA stands for supervisory control terms and data collection. HMI is about  the human interface with the machine. These systems usually refers to an industrial control system: a computer system to monitor and control a process. These processes include water treatment and distribution, wastewater collection, gas pipelines, irrigation and distribution door, wind farms and environmental systems. Other processes such as monitoring of buildings, airports and ships, remote alarms, device status and maintenance status of different devices.


Web server embedded on the device:

• All the events of the system will be converted into HTML pages to track web, intranet settings for tracking control or IP settings for remote monitoring over the Internet.

• Users will be able to see their data systems in real time and sends commands (change set point, control equipment on or off), using the Web server.

• All commands and security password set-points. Orders received from your browser to be forwarded to the sensors and actuators is like when you are at the computer base station.

• Easy to use by  the setting for events and Web servers.

Your existing project is display on HTML 5.

• Project your existing display HTML5 format files. What you see is simulated working process of the event is what you see in your browser.

• Other HTML5 pages created by other manufacturers may also be used in the system.
