TRS

General Characteristics

The TRS Temperature and Humidity Recording System is a computer measurement system. Its basic tasks include: collecting, recording and displaying data on temperature and humidity eg. in cold stores, production halls, etc. Main elements of the system are: measuring and indicating devices, data transmission cable, protocol converter with a power supply and recording software. Optionally we also recommend using an surge protector to protect the computer and devices plugged into a common electrical power source. The control software allows connection of GSM module to PC and sending reports (eg. alarm state report). User definable ALARM STATES are related in free way to thresholds/ /failures of measurement devices. There is possibility of individual enabling/disabling of reporting of any ALARM STATE and fully configurable signalling of ALARM STATES by digital outputs (SOC-8), short text message SMS (GSM) or sound signal (TRS-B1a).
 
At present the TRS System includes: ambient temperature transducer (TRS-01a), temperature transducer to work with a Pt100 sensor (TRS-02a), temperature and humidity transducer (TRS-04a), ambient temperature transducer with display (TRS-11a), wall mounted indicator (TRS-10a), additional power supply (TRS-09a) and sound signal device (TRS-B1a). Data is exchanged and facility devices are supplied by means of a fourconductor screened transmission cable (maximum length: 1 km) connecting all system devices to the computer. Up to 127 devices can be connected to the system and thanks to this we can reduce the number of "cable routes", which is a basic factor that increases costs. Data between transducers operating to the RS-485 industrial standard and the office computer equipped with the RS-485 standard, are exchanged by means of the protocol converter with power supply (SRS-2/4-Z16-B1a). We placed the measuring converter power supply in one casing to make assembly as easy as possible. The System is mainly used in the food industry: in meat, fish and milk processing plants as well as in all other places where continuous measurement and recording of temperature and humidity are required. The standards impose an obligation to record temperature in rooms with controlled temperature and to store the data for more than 2 - 3 years (depending on the industry).

Computer Communication

The Piggy software is used for the computer communication system. The basic task of this application is to collect data from a network of scattered measuring devices, to store results in a database, present them in tables and diagrams as well as to create and print reports.

Piggy Soft application offers:
- temperature and humidity recording from a long period of time,
- data displaying in the form of a diagram,
- report generation within a specified period of time.
During operation, results of measurements are presented in the form of a diagram. On the right side of the diagram there are controls that enable definition of data presented in the diagram and determination of a starting and ending dates of presented data. The user may select from the list those devices whose measurements will be presented in the diagram.
