1 icp 1000 Wireless GSM Based Remote Monitoring Unit for Transformer Rectifier Unit

2 The GSM based remote monitoring unit icp 1000, for Transformer Rectifier (TR) monitoring, is a highly accurate, compact, low power, low cost, micro controller based unit with built in GSM Modem which enables continuous Centralized Monitoring of TR parameters and at the same time notification for any alarm occurrence at central station as well on the configured cell numbers. This system enables easy & wireless centralized monitoring of all TR parameters like TR Voltage, TR Current, and Reference Potential and A.C Interference voltage (optional). The icp 1000 can be installed in the existing TR Unit and can directly accept TR parameters without the need of any transducers. The icp 1000 acquires all analog and digital parameters and transmits it to the central station at the programmed periodic interval. The icp 1000 notifies the user for the occurrence of any alarm signal and gives the data to the central station irrespective of the periodic interval. At the remote end, the Data could be received using a GSM interface module connected to the PC installed with the CP Software REMOTE DATA. Remote Data displays the data in the Analytical and graphical format and stores this data in the standard database, which is used for generating, reports for further analysis of the structure under protection. The data broadcast schedule is fully programmable from 1 broadcast per Minute to one broadcast per day.

3 Apart from sending the TR data to the remote stations, this unit also Logs data in its Non Volatile memory at the programmed logging interval, thus it also is a data logger. It can store about 7000 readings which can be downloaded on the Laptop computer using a RS232 port provided on the unit. The data stored in the internal memory can retain for 10 years without any external power. The detailed technical specifications of the unit are as under: Unit : icp 1000i / icp 1000iAC : Micro controller based intelligent TR Monitoring Unit with built in GSM Modem. SPECIFICATIONS Analog Inputs Computed Inputs : High accuracy, High Input Impedance > 10Mohms, 16 bit resolution, Differential Input with high common mode rejection ratio CMRR. CH 1: VDC (for TR output DC Voltage) CH 2: mv (for TR Output Current) CH 3: 4V to +4 V DC (for Reference potential) CH 4: 0 300VAC ( Through power supply inputs) : Apart from the acquiring the physical Analog signal, the icp 1000 also Computes for TR Run hours. It samples and logs the TR Input AC power every minute and computes for the TR Run hours. This Reading is used by Remote Data Software to generate the Up Time Report of the TR Unit. The icp 1000 also continuously scans and checks for Alarm conditions listed below on the basis of Reference potential Over Protection Under Protection Reference Fail The Set parameters for the above alarm conditions can be feed through the local keypad available on the front panel of the icp Status Inputs : Pre Programmed Alarms Indication for the below conditions DI 1: Over Protection. DI 2: Under Protection. DI 3: Reference Fail DI 4: Door Open Alarm GSM Interface Built In GSM Modem for broadcasting data to the Central Station at the programmed periodic interval. The Data are transmitted in the form of SMS.

4 Alarm Notification The icp 1000 will notify to all the configured cell numbers on their cell phone along with sending the notification to the central stations. Over Protection. Under Protection. Reference Fail Door Open Alarm AC Input Power Fail Centralised Monitoring The icp 1000 has built in GSM modem to communicate with the central station over the GSM network. The icp 1000, send the TR Data with exact time stamp to the central station at the programmed Periodic Interval. At the central end the PC is installed with the GSM module and centralized monitoring software Remote Data. The icp 1000 sends alarm information with exact time stamp to the central station and the configured cell numbers, irrespective of the Periodic Interval. Remote Data accepts the data received from the icp 1000, displays them in graphical and analytical formats and stores them in database to generate Reports and Graphs. It is also possible to send configuration details like Setting Data/Time, Setting/ changing Periodic Interval and Setting of cell phone numbers for getting Alarm notifications. Local Keypad & Display The icp 1000 consists of a 3 x 6 matrix membrane keypad and a 16 x 2 LCD with back lit for entering local settings and viewing TR parameters locally. Local settings such as Setting Data/ Time Setting Start Time for Periodic sending of data to the Central station. Setting Periodic Interval Scaling Entering cell numbers for alarm notifications. Setting ID of the icp Can be done using local keypad and LCD. The LCD will normally display TR Voltage TR Current Reference Potential TR Run Hours GSM Signal Strength GSM SIM registrations. The icp 1000 can also be remotely configured for some of the above parameters from the central station.

5 Programmable Periodic Interval Data Storage Time Stamping Protection Enclosure Ingress Protection Power Supply Battery Back UP Temperature Environment Test The Periodic interval can be programmable from 1 broadcast /Hour to broadcast / 24 hours. Data can be stored in the non volatile Memory. About 7000 readings can be stored without downloading. Local Data retention up to 10 years without any external power. The Logged Data in the icp 1000 can be downloaded on the Notebook computer using the serial communication port provided on the front panel of the icp The icp 1000 is supplied with Data downloading software LogData. LogData downloaded the Data and generates Reports and Graphs. The Unit has precise, accurate Real Time Clock (RTC) for exact time stamping of data. The Input channels have full protection against high voltage surges and continuous over voltages. The Enclosure is of ABS material and has an ingress protections level of IP54. The power supply of the icp 1000 can accept below both voltage ranges 120 VAC to 320 VAC For 4 Hours on AC Power failure.
