 |
The system can
check the numbers and distribution of the current personnel
underground and the location of any personnel at current
time or an appointed time. It can check the working trace
of any personnel in current day or an appointed day. |
|
It can display the personnel information
of any selected area, and can display all the time information
(including historical information) of the personnel passing
by of any selected receiving antenna. |
|
It can make realtime tracing for specific
personnel. |
|
|
Functions of alarm |
| |
|
By setting the
down-to-mine time, the system can send alarm for the personnel
being overtime in the mine underground and display the
information of the related personnel with name and etc.
|
|
Equipped voice station in some important
chambers and severe situations (such as blind alley, etc.),
can effectively prevent persons who will break rules and
regulations to enter, and the persons will be on the record. |
|
The system will automatically alarm
when the number of person exceeds the regulated number
in a particular dangerous area for preventing person's
continual entering into. |
|
|
Functions
of checking on work attendance
|
| |
The system can display the exact time
of each personnel going down and up to the mine. And according
to the type of work (to stipulate the full worktime) the system
can judge full worktime of different personnel and determine
effective work. It can make classified statistics of the numbers
and time of the personnel going to the mine underground monthly
for checking, and it can print related record forms such as
monthly attendance record and down-to-mine statistics of arbitrary
period. |
|
Functions of information
network |
