Devices for remote monitoring of sensors via Ethernet network and remote controlling of power supply sockets with a built-in GSM modem have a feature of sending periodic SMS reports about a status of sensors and relays to service staff. These SMS reports allow to be constantly informed even of those monitoring objects that do not have a local data transfer network. Receiving the information on conditions of equipment operation, attempts to access the object or any other unplanned actions in time allows to avoid accidents at the object, thus eliminating equipment downtime and financial loss of business.
To receive periodic SMS reports about a status of sensors and relays at the object, there is a need to have:
- NetPing devices with a built-in GSM modem (UniPing server solution v4/SMS, NetPing 8/PWR-220 v4/SMS, NetPing 4/PWR-220 v4/SMS, NetPing 2/PWR-220 v4/SMS, NetPing 2/PWR-220 v1/SMS);
- connected sensors for NetPing devices. The information about connecting sensors can be browsed in the user guide of a corresponding device;
- a cell phone to receive SMS reports
Configuring NetPing Device for Sending Periodic SMS Reports
An algorithm of configuring NetPing devices for sending periodic SMS reports, for example, within the next conditions, will be shown in the article:
- A temperature in a server room is above 30°C.
- A door of a wiring closet is open.
- There is a leakage in a server room.
Let us suppose a door sensor of a wiring closet is connected to the line IO2, a water leakage sensor is connected to the line IO3, a temperature sensor is connected to the corresponding socket of a temperature sensor of a NetPing device.
The process of configuring a NetPing device for sending periodic SMS reports is performed in a device web interface in several simple steps.
To do this, there is a need to go to the web interface by entering an IP address of a device in the browser (on default 192.168.0.100), and log in (a default username and password are: visor, password: ping).
Go to the page «DISCRETE IO» to configure IO lines. Set an operation mode of the lines IO2 and IO3 to «input», because a door sensor and a leakage sensor are connected to them. In addition, there is a need to use one more IO line, for example, IO1, to form an SMS report. An operation mode of the line IO1 is better to be set to «logic output» in this case. After changing parameters, save the settings by clicking the button «Apply changes».
Setup the description for changing a logic level and adding an IO1 line into the contents of an SMS report through the notifications window by clicking the button «Setup».
In the window «Notifications for the IO line 1» check a checkbox «Include in Summary Report» in the column «SMS» and write a description of numeric values: 1 – is normal, 0 – is a problem. Apply the changes by the button «Save changes».
Therefore, the contents of an SMS report was determined. Within normal conditions an SMS with the text "NETPING Sensor summary: O1=1 NORMAL" will be sent, and if there is a problem, an SMS with the text "NETPING Sensor summary: O1=0 PROBLEM" will be sent.
Enable SMS notifications when a door sensor triggers. In the column «SMS» check checkboxes «Front (level change 0->1)» and «Decay (level change 1->0)». Apply settings by the button «Save changes».
Enable SMS notifications when a leakage sensor triggers. In the column «SMS» check checkboxes «Front (level change 0->1)» and «Decay (level change 1->0)». Apply settings by the button «Save changes».
At the page «Temperature» of a device web interface configure a range of normal thresholds of the temperature from 10°C to 30°C, exceeding which a status of a temperature sensor will change.
Enable SMS notifications when temperature values leave the thresholds of a temperature safe range. To do this, click the button «Setup» in the settings of a corresponding channel of a temperature sensor.
In the window that appeared «Notifications for Temperature Sensor 1» in the column «SMS», check checkboxes «Temperature is above safe range», «Temperature is in safe range», «Temperature is below safe range», «Sensor fault» and save settings by clicking the button «Save changes».
To receive an SMS report on a status of all sensors you are interested in, there is a need to use logic rules of a NetPing device. Logic rules will set a logic level of the line IO1 depending on conditions of triggering sensors. To configure corresponding logic rules, there is a need to go to the page «Logic» of a device web interface and write the rules, shown at the screenshot below.
In addition to logic rules it is necessary to setup the module «Thermo(Hygro)Stat», which determines the status of a temperature in a current moment of time. On the basis of data of the module, logic rules can execute programmed actions. The module «Thermo(Hygro)Stat» is configured at the page «Logic». A configuration of the module is made by selecting a number of a necessary temperature sensor (Temperature sensor №1) and setting a triggering threshold (threshold: 30°C).
The last step of configuring a NetPing device is indicating phone numbers for sending SMS reports and SMS notifications as well as a time of sending, when periodic SMS reports will be sent. These parameters are set at the page «SMS» of a device web interface.
Let us setup the time of periodic SMS reports to 08:00 and to 17:00, i.e. such summary will be sent daily in a specified time.
As a result of settings described above, sending of periodic SMS reports on a status of the sensors you are interested in is implemented. I.e. if a temperature at the object exceeded the threshold of a safe temperature range, a door of a wiring closet opened or there was a leakage, a service staff would receive an SMS report with the problem. If none of the sensors triggered, then an SMS report would contain the information about a normal operation of a monitoring object.
In addition, such SMS report helps to understand if a NetPing device works at the object and if a built-in GSM modem did not freeze, and if a connection with a mobile operator is not lost, which in turn allows to get the information about triggering of sensors instantly in any moment of time. Furthermore, in the moment of triggering of configured sensors, a service staff will receive corresponding SMS notifications, on the basis of which it is possible to react instantly and thus prevent accidents at the monitored object.
