Automated record keeping system of coal mines (PSI)
The company Zavod Amplituda LLC specialized at production and repair of equipment for mining industry based upon technical facilities of its own design has worked out the automated record keeping system (PSI).
PSI is designed for gathering of information on operation time (descending, ascending, movement) of underground workers at coal mines, primary processing of obtained information in the system controllers, storage and transfer of information into Ethernet for users of record keeping systems, access control etc.).
PSI is made based upon equipment system AKORD according to Technical Specifications of Ukraine 30.00-30482603-005:2008.
Functional characteristics of PSI:
PSI technical facilities are designed for around-the-clock service.
PSI enables maintenance and current repair of any input/output channels without reducing execution of real time tasks in other channels.
Single-type PSI units are interchangeable.
Data reader units are no-contact (SCh-1) from RFID-tags or readers KTN from metal tokens.
Standard technical specifications of no-contact reader devices SCh-1:
ÌÊ-2 with IRPS interface (current loop) –up to 10 km;
SCh-1 case version is explosion-proof with spark-proof circuits and protection level at least IÐ54.
Modules of concentrators ÌÊ-2 are designed to control operation of SCh-1 devices (one MK-2 controls 5 (five) readers SCh-1 or KTN), for primary gathering of information from them and its transfer to system controller KS-1.
ÊÑ-1 provides for signal delivery to control warning alarm according to conditions determined by the Customer.
PSI is powered from AC or DC mains 220V by one or two feeders.
Record of service data base contains:
SCh-1 number, TAG number (token number), time;
prying attacks SCh-1, ÌÊ-2
