it@mms-adv.gr — Thu, 22 Oct 2020 13:53:09 +0000

Introduction

Pressure in a municipal water system needs to be maintained kept at 0.3 Mpa in order to be able to deliver a proper stream of tap water to homes and businesses. Many water companies all over the world use remote monitoring systems in order to be able to immediately respond to leakages and sudden drops of water pressure.

Requirements

- Monitor pressure in points of interest in a distributed municipal water pipeline system.
- Monitor and report data from every pressure point to a central database or SCADA system.
- Alert immediately on sudden pressure drops threshold limit.
- Take advantage of a cellular communications network using SMS and GPRS communications.
- High expandability.

Proposal

Infinite SCOM-100 is a GSM/GPRS Edge RTU designed specifically for remote monitoring systems. Traditional cellular products use polling to request data, which requires a static and public IP. SCOM-100 can communicate with a central database or SCADA system regardless of what kind of IP address it uses over GPRS.

In addition, it provides real time data from the remote location, which is impossible with a polling system. Moreover users at the central station can issue commands to the remote stations to perform standard control actions because the SCOM-100 supports local functionality, making it a truly PC-free solution.
Traditional polling systems can take up to 3-4 minutes to obtain four different pressure values from four different monitoring sites. The SCOM-100 GPRS communications deliver the information in just a few seconds. Furthermore receive SMS alerts instantly while maintaining GPRS connectivity. SCOM-100 communicates via SMS and GPRS with users, PCs, other SCOM-100 units in M2M all at the same time. The SCOM-100 OPC Server software integrates seamlessly with any SCADA system.

Why SCOM-100

All-in-one cellular GPRS quad band solution
Real-time data acquisition
Easy to implement and maintain
Seamless connection to SCADA via OPC server

Toll free call access control

it@mms-adv.gr — Mon, 12 Oct 2020 08:40:46 +0000

Introduction

More and more industrial and trading companies are upgrading their security systems to include automated gates. Gate access control of parking areas, loading and unloading zones are common targets. ARC-10 GSM Controller, combined with a dedicated PC application for user management, can provide a secure entrance access control to a company’s facilities.

Requirements

Low cost user identification without special badges or dedicated remote controls.
Unattended gate accessibility.
Convenient user management.
Remote control capability of the gate accessibility.
Tampering alarm via SMS.

Proposal

Infinite ARC-10 GSM controller provides a secure entrance access by receiving a toll free phone call from a registered user. A special contact, connected to an ARC-10 digital input, can initiate an SMS alert to security personnel, in case of a tamper attempt. Up to 10 power users can be qualified to control (enable or disable) the gate accessibility via SMS and receive alerts from the unit.
The ARC-10 Configurator application can be used to manage a user database and synchronize it with the ARC-10 memory. The PC application communicates with the GSM controller via an occasional or a fixed serial connection. A laptop can be used for occasional connections. RS232 to RS-485 converters can be applied to establish a fixed serial connection from a distant point.

ARC-10 Configurator synchronizes every modification of a database record with the corresponding entry in the ARC-10 memory. In the above illustration, a user’s phone number, which was previously edited in the database, is synchronized, by automatically executing the following 3 steps:

The erroneous phone number is removed from the device memory (CUD command),
The correct phone number is entered (CUN command).
If the commands are executed successfully, the edited record is validated, else the editing is cancelled.

M2M Reservoir Level Control

it@mms-adv.gr — Wed, 07 Oct 2020 08:24:13 +0000

Introduction

The water level regulation of a reservoir, used for irrigation purposes, is the requirement for an M2M control system. The reservoir is located in an off-grid area, on a hill. A pump house located below the hill, feeds the reservoir from a near river. The system is shown in the figure below.

Proposal

A BSC-50E battery powered RTU with an ultrasonic sensor, is used for tracking the reservoir water level. BSC-50E sends M2M commands to an ARC-10 GSM controller, which controls the pump operation through its relay outputs. The pump automation system (e.g. a PLC) supports the following functions:

Function	Actuator / Indicator	Action
Start Operation	Push button (Start button)	Enable Remote control, Turn Pump ON for t=T1 ¹⁾
Stop Operation	Push button (Stop button) or Digital input IN1	High pulse on IN1–> Cancel system operation
Remote Control	Digital input IN2	High to Low transition –> Turn Pump ON for t=T2 ²⁾, Low to High transition –> Stop PUMP)
Thermal protection	Digital output OUT1	Low –> Normal operation, High –> Protection active (Operation cancelled)

¹⁾ T1 is the time, depending on the pump flow rate, needed to fill the reservoir from empty state to a level between H and HH.
²⁾ T2 is the time it takes to reach a level between H and HH, starting with water level L.

ARC-10 outputs DO1, DO2 are connected to IN1 and IN2 of the pump control system respectively. The thermal protection indication (OUT1) is connected to ARC-10, digital input 1 (DI1).
On the other side, an ultrasonic sensor (Massa M300) is connected to BSC-50E, analog input 1 (AI1). Two alarm limits are set on the analog measurement:

Alarm limit low, which corresponds to level L.
Alarm limit high, which corresponds to level H.

The water level is logged every hour. A level switch, indicating the HH water level, is connected to BSC-50E, digital input 1 (DI1).

Operation description

After start up, the pump feeds the reservoir, until the water level reaches the high limit (Level H). In the meantime BSC-50E scans the water level every minute.
On reaching the high limit, BSC-50E sends an M2M SMS, commanding the ARC-10 unit to switch DO2 on. The pump is turned off. At the same time, BSC-50E switches level scanning to a lower rate (e.g. every 15 minutes), to save power.
The pump remains in the hold state until the water level drops, due to irrigation flow, below the low limit. Then BSC-50E sends an SMS, commanding the ARC-10 unit to switch DO2 off. The pump is turned on. At the same time, it switches to higher sampling rate (every minute) to keep track of the reservoir filling.
Once a day, BSC-50E sends the water level logs to a system administrator.

Alerting

If the water level reaches, for any reason, the HH limit, the level switch activates an alarm on BSC-50E, DI1. BSC-50E sends an SMS command to the ARC-10 unit, to switch DO1 on for 2 seconds. The feeding system operation is cancelled. An additional SMS is sent to maintenance personnel, alerting for the malfunction.
In case of pump overheating, ARC-10 sends a respective alert to maintenance personnel.

Battery lifetime

The lifetime of the BSC-50E internal battery (LSH-20) depends on the water feeding cycles per day, as shown in the table below:

Feeding cycles	M2M SMS	Daily consumption [mAh]	Battery Lifetime [Years]
2	4	16.7	2.13
4	8	20.2	1.76
6	12	24.6	1.44
8	16	31.0	1.14
10	20	37.4	0.95
