All modules of the giant control support SMS alarm. If you need to add WeChat alarm push and variable history recording functions, you can choose them separately. The advantage of WeChat alarm is that it does not generate SMS fees

Product Details

WeChat alarm push andvariableThe historical records are divided into three levels,Unrestricted number of followers on WeChat, multiple followers on the same module receive WeChat push alerts without duplicate counting

Model: GRMHIS-S Small3 minute intervals, 32M data capacity, capable of recording 2000 historical alarms,Up to 50 WeChat push notifications per day, charge 200 6% value-added tax invoice

model:GRMHIS-M1 minute interval, 128M data capacity, capable of recording 5000 historical alarms,Up to 100 WeChat push notifications per dayCharge 450 6% value-added tax invoice

model:GRMHIS-H Large5-second interval, 512M data capacity, capable of recording 10000 historical alarms,Up to 200 WeChat push notifications per dayCharge 850 6% value-added tax invoice

The above fees are one-time charges and lifelong useIf you need 2 modules to use, then you can purchase 2. When purchasing, add one model and quantity, model: GRMHIS-S or GRMHIS-M or GRMHIS-H, with the model difference as described above

The selection of variable history records first requires special attention to the collection and recording period of variablesFor example, if you need to collect and record data every 10 seconds, you must selectGRMHIS-H， If it only needs to be collected once every minute or more, you may consider choosingGRMHIS-M，Next, consider the variablesCapacity of historical records

Advantages and features of the historical recording function of the Giant Control GRM module: The historical data function of GRM500 has the ability to resume transmission after disconnection. Even if the GRM500 cannot connect to the server due to network interruption or card arrears during recording,The data recorded regularly will be added to the cloud server after the module goes live next time, and historical data will not be lost

matters needing attention:

Variable history records can only record the number of variables up to 160 bytes, which is equivalent to 37 32-bit floating-point numbers or 64 16 bit integers

A 3-minute interval indicates a fast recording period of 3 minutes,1-minute intervaltime representationFast recording cycleIt's one minute,5-second intervaltime representationFast recording cyclecorrect5 seconds

Calculation of variable history capacity and recording time:Record once every 3 minutes with a capacity of 32M

Scenario 1: Long data record (37 analog quantities, 5 switch quantities, 160 bytes in length): 320 days

Scenario 2: Medium data record (20 analog quantities, 5 switch quantities, 90 byte length): 540 days

Scenario 3: Short data recording (10 analog quantities, 10 switch quantities, 50 byte length): 880 days

Scenario 4: Short data record (5 analog quantities, 28 byte length): 1370 days

Others can be analogized, calculated based on capacity, record length, and timing interval ratio
