Monitoring system with sensors via GSM
PRELIMINARY !
FEATURES:
1. Wireless data acquisition of values from 16 sensors on RS485 link
- Connection of up to sixteen Tx41x and Hx431 sensors with RS485 output.
- Easy sensor installation by only entering Modbus address. Type of device and available values are detected automatically.
- Advanced detection of error states (communication error with sensor, measurement error).
2. Sending of actual values to data acquisition system
- Transfer and storing of measured data to data acquisition system. Client has database installed on the server for storing measured values. Using of own data acquisition system enabled.
- Data transfer is realised via SOAP protocol (modem sends in selected interval XML files with actual measured values to data acquisition system).
3. SMS queries about actual values
- By simple sending SMS message it is possible to receive actual values from any sensor. If modem recognizes in incoming SMS request for sending actual values, values are sent by return in SMS message.
- Limitation of phone numbers for sending SMS queries is enabled.
4. Alarm SMS messages
- If opening/closing of relay of a Hxxxx transmitter was detected.
- Communication error with sensor or measurement error.
- Report about sensor replacement or configuration change.
5. Prepared for communication via M2M Talk server
6. Setting of GPRS modem
a) Local - setting via RS232 serial link- Putting into operation (setting of SOAP server, addresses of sensors, phone numbers for alarm SMS).
- Firmware upgrade.
- Detection of error states (download of log file, etc.).
- Most important parameters of GPRS modem can be remotely set by means of SMS messages (SOAP protocol, M2M Talk server, GPRS communication).
- Firmware upgrade in modem.
- Service commands (GSM status, modem restart, ëtc.).
Each Tx31x or Hx331 sensor in monitoring system is connected to "its" GSM modem LP040.
It is necessary order several items from optional accessories.
Minimum set of one sensor connected to GSM contains:
- sensor of Tx41x or Hx43x family- MP021 RS232/RS485 converter, including ac/dc adapter
- LP040 GSM modem
- GSM antenna
- Ac/dc adapter 230V-50Hz/24Vdc/24W
- QMS2901 cable for setting of modem
- SWR009 Database Sensor Monitor software Comet
