Remote control and monitoring via GSM
mobile telephones using SMS text messages for the PicoServ
System.
PicoServ is all about providing simple remote
access. Adding the PicoServ SMS gateway extends monitoring and
control of equipment or systems connected to PicoServ to any GSM
mobile phone using SMS. The PicoServ SMS gateway module is
designed to interoperate with any of the PicoServ expansion
modules and can be installed with or instead of the PicoServ web
server module.
Connection to the GSM network is via a serial interface and the
GSM 07.05 protocol, supported by many GSM handsets and GSM
modems.
By extending the remote control and monitoring possible with a
PicoServ system to the mobile phone, the SMS Gateway module can
provide many more applications possibilities. The system can
provide truly remote personal situation awareness. Almost any
number of mobile users can contact and request information from
a PicoServ based system and up to 16 nominated users can receive
notification of events or when preset limits are reached.
Input/Output
The SMS Gateway module can be used with all the standard
PicoServ interface modules which simply plug into the gateway
and provide a range of analogue and digital inputs and outputs.
This method provides a ‘no development’, real-world interface,
making the input and output variables available to the user via
a mobile phone using text messages.
Remote Control with Text Messages
Web Server
The SMS gateway can be used with or without the PicoServ Web
Server Module. When used in conjunction with the server module a
web browser interface can be provided to the SMS gateway
allowing the creation of a simple web based SMS messaging
centre. Text messages can be sent to any mobile number as well
as providing web based SMS gateway administration.
Connecting to the Network
The PicoServ SMS Gateway module uses an RS232 serial port and
the GSM07.05 protocol standard to interface to the GSM network
via a standard mobile phone or GSM modem which has a serial
interface. Most GSM mobile devices with the option of a serial
port support the GSM07.05 protocol. A network subscription (SIM
card) is also required. The type of subscription needed will
depend on the type of application, particularly the mix of
outgoing and incoming SMS text messages.
