4. Function
It has the following control function.
(1) Communication function with mail server.
Mail transmission and reception are performed between this device and a mail server.
(2) Information notification function at set time (linkage function with server)
Voluntarily notify information to the server at the set time (daytime batch,
nighttime batch)
(3) Alarm notification function (linkage function with server)
It notifies information to the server autonomously according to the event generated
by this equipment. The types of events are as follows.
a) Intrusion alarm function
b) Out-of-area alarm (generation / release) function
c) Battery disconnection alarm (generation / release) function
(4) Command reception processing function
To perform processing to a command transmitted from a server.
Command reception processing function
a) Machine status inquiry function
b) Intrusion alarm effective time setting function
c) Area setting function
d) Communication stop / resume function
e) Communication test function
f) Communication capacity confirmation function
g) Calendar change function
h) Time difference setting function
(5) Communication function
It has the following functions to communicate with the server.
a) Destination setting (fixed)
b) Batch transmission timing
c) Retry transmission
(6) Operation time acquisition function
While the hour meter signal is ON (while the engine is in operation), the time is counted,
and the count value is integrated. Get the total operating time. Note that total operating
time is stored in nonvolatile memory.
(7) GPS information acquisition function
Acquisition of GPS information shall be made every 30 minutes (0 minutes, 30 minutes
per hour). After starting the device, the GPS module is started immediately.
When the GPS information can be positioned normally, the date and time of the GPS
information is reflected on the RTC of the apparatus. When the positioning fails,
the RTC is not updated. The time correction shall be implemented 24 hours after
the previous implementation times. Positioning satellites (NMEA sentences) shall be
GPS only (GLONASS is not used). GPS data is received (application acquires data)
At ｔｈe time of GPS positioning. However, when the application does not perform
positioning even after one minute has passed from the GPS information acquisition time
(start), the acquisition processing is ended as non-positioning.
(Surveyor system: WGS-84)
6/17
(8) Sleep control function
a) When all the following three conditions are satisfied shift to sleep to reduce
current consumption.
1) GPS positioning is not performed.
(The application is not acquiring GPS information)
2) No response processing has been performed by receiving the command or by receiving it.
3) While the engine is stopped (the hour meter signal is OFF)
b) To recover from sleep, perform immediately under any of the following conditions.
1) Engine operation (hour meter signal ON)
2) Activation signal input from communication module (SMS reception from operation)
3) Time reached at the date and time setting
4) Serial input from PC 5) Changing battery connection status
(9) Setting information holding function
Save necessary setting values in nonvolatile memory.
Items to be saved are as follows
●Items to be saved during operation
・Total uptime
・Current battery alarm condition
・Intrusion alarm effective setting time, day of the week information
・Unsent mail data
・Area information
・Communication stopped state
・Number of mail transmission / reception bytes, number of mails
・Mail transmission retry count accumulated value
●Items to be set at factory shipment, items to be held
・When checksum Exclusive logical calculation value
(10) Fail-safe function
To incorporate a fail-safe processing for preventing hang-up into software or hardware,
and to make the processing only fail-safe and not to occur frequently.
A) Reset by CPU's WDT time-up
b) Reset by CPU independent WDT time up
C) Restart by software at system error
d) Regular Reset of Communication Module
(11) Serial communication function with personal computer
Communicate with the personal computer using RS232C 1ch.
(12) Display (LED) function
a) When the engine is on and it is within range, blinking at a slow cycle
(1000ms on / 1000ms off)
b) When the hour meter signal is ON, and when it is out of service area,
it blinks earlier (200ms on / 200 m turn off)
c) It turns off when the hour meter signals OFF or when the battery on the
construction machine side is not connected (when the built-in battery is operating)
(13) Date and time setting function
Features such as GPS data acquisition, daytime and nighttime batches are available
that can be operated in time. A request time is set to an RTC (for alarm), and when
the request time comes, the request time is notified to a connection server.
(14) Software rewrite function
The software is rewritten from the external personal computer to the present device
7/17
via serial.
(15) Hardware protection function
To avoid an internal temperature rising of this device, mail transmission shall be as
follows. When a trigger for mail transmission occurs, if the temperature is equal to or
higher than a certain temperature, the mail is not transmitted, and the mail is saved as
non-transmitted mail in the nonvolatile memory.
Maximum of 10 mail transmission processing (including retry due to communication error)
shall be made.
If the tenth e-mail transmission fails, retrying is not performed even when retry is
possible
