Description of the system

A device mounted in a stationary object reads signals from that object. Data from the monitored object is transmitted online with the use of GPRS / GSM or WiFi networks, these data are collected on the server and made available to users of the NiTcom system. With this form of communication, data from all monitored objects is updated on the server in real time.

This allows you to observe any parameters of the object on a regular basis, and thanks to bi-directional communication it is possible to change the parameters of the device and control the object by the operator or by changes of the state of another object.

Access to current and archived data stored on the server, and their presentation of the selected object, group, or all objects, is provided by a dedicated NiTcom application provided with the communication controller.

The customer, after signing in to NiTcom, gets access to their objects. One customer can have a freely defined number of user accounts (employees) with different privileges. The object data, status of monitored inputs, and alarms are displayed in a table.

The user can use additional options to filter data by time intervals, normal operating states and / or alarm states or auxiliary sensor input states. This data can also be viewed as a text report. It is also possible to generate logistics reports. Using a dedicated NiTcom application facilitates ongoing operations on objects.

Device StTr®GSM-450 has:

  • GSM/GPRS module,
  • GPS module,
  • simplified inputs / outputs interface,
  • possibility of communication in SMS, GPRS,
  • register for 16,000 entries (buffer),
  • backup power supply (battery)
  • 8 binary inputs
  • 4 binary outputs

Device StTr®GSM-750 has:

  • GSM/GPRS module,
  • GPS module,
  • simplified inputs / outputs interface,,
  • possibility of communication in SMS, GPRS,
  • register for 16,000 entries (buffer),
  • backup power supply (battery)
  • 16 binary inputs
  • 8 binary outputs
  • 4 analog inputs

The controller mounted on the pump stations are connected GPS antenna and GSM and additional sensors – eg.:

  • pump work,
  • door opening / closing (burglary),
  • pump failure,
  • liquid level,
  • power / battery voltage,
  • other state sensors according to individual solutions.

In addition to object-oriented facilities, the transmission, monitoring and control system is created by a server group. These are: communication servers that perform direct communication with location devices, receive and process information received on-line and central servers – database server, digital map server, server for clients queries. This modern, authoritative, proven and stable operating system, with the ability to extend a dedicated communications server in its own Surveillance Center, provides low cost GPRS transmission.

The next element of the system are client applications, including dedicated NiTcom application – special software that downloads data from servers.

Using the data stored on the server and client computer, you can create a variety of reports that contain information about the object and its history. The object data, location data, status of monitored inputs, and alarms can be compiled in reports that allow for a subsequent analysis of the state of the objects.The user can use additional options to filter data by time intervals, normal and / or alarm states, or auxiliary sensor input states.

Example application of the StTr ® GSM-450 device at the pumping station:

The StTr ® GSM-450 device mounted on the pumping station collects and transmits to the communication servers information about the processes taking place on the monitored object, which can then be analyzed by the user through a dedicated NiTcom application. The standard monitored signals are:

  • The presence of a power cabinet
  • Unauthorized access to the object
  • Operation of individual pumps
  • Failure of individual pumps
  • Alarm level
  • Dry run level

Example of use of the StTr ® GSM-750 device on the sewage pumping station

The StTr ® GSM-750 device thanks to the 16 binary inputs can, in addition to the signals specified for the StTr ® GSM-450 device, monitor additional signals that are individual user solutions.In addition, it performs role of the driver of the processes taking place on the object. Based on signals received from sensors, binary outputs are triggered to actuate specific devices on the object. Pump starting and stopping is based on the signals from the hydrostatic probe of the level of the pumped medium. The device has a pump protection function in case of a minimum level, a failure of the pump or its dismantling when a pump is excluded from the control cycle. Using the StTr ® GSM-750 also allows you to remotely turn on or off a pump from NiTcom applications.
