| SMS (external GSM modem)
gsm alarming over SMS throught external GSM modem The alarm status notification can be realized with redirecting the Email to SMS. Because of possible failure, an independent GSM modem can be connected directly to the Poseidon unit or to the server which supervises with several Poseidon units.
Methods of SMS sending
* SMS sent via GSM modem from server (for example via program PN Eye)
On a local server, a program runs and via SNMP supervises the state of one or more Poseidon units. In Alarm status it sends notice via SMS via GSM modem which is connected directly to the server.
o (+) For more Poseidon units central point is advantageous for setting all parameters in one step
o (+) Alarm is always logged by an independent authority, it can be sent to Email as well
o (+) SMS format is programmable
o (+) Via SMS request, you can verify the state of several connected Poseidon units and their sensors
o (-) It is necessary to guarantee running application where to send SNMP Traps from Poseidon units and transmit SMS. This means to rely on:
+ The local server and its program
+ The connection of server - Poseidon unit
+ The GSM modem
* SMS sent via GSM modem connected to Poseidon RS-232 port
Poseidon and GSM modem constitute an independent system. This construction is very resistant in case of many types of failures. However, this reliability does not apply on the failure of the power supply and the GSM network.
o (-) It requests GSM modem connected to each Poseidon
o (-) Via SMS, Poseidon sends only basic information about Alarms, It is not possible to know the state
o (+) Stable and on the network infrastructure independent solution |
