TETRA IPC Systems

When implementing IPC in wide spread territories, and especially in the conditions of absence of any radio communication or a complicated relief of the district, there are questions how to choose optimal wireless technology of transmission of telemetry data and control commands with sufficient degree of reliability and security.

The use of public cellular communication systems or broadband wireless access for wireless IPC systems require significant capital and operating costs. The same time there is a risk of dependency on the mobile operator commercial policy, quality of service and fault tolerance, the timing of response to accidents and their elimination, etc.

There are also private technical monovendor solutions of individual manufacturers based on LoRaWAN technologies, but they do not have a full-featured direct channel of remote control, which makes their use impractical in systems where constant monitoring with guaranteed operational control is needed. Their purpose – only the removal of accounting data, without the possibility of transmitting control signals with a sufficient degree of reliability.

The solution offered by our company on the organization of digital wireless system of automatic control system on the basis of radio communication system of the TETRA standard is the optimal solution if:

you build IPC system "from scratch" to cover a large area or production facility, which has difficulties with the organization of the cable transport network;

there is no or not reliable infrastructure (radio coverage) of public networks of mobile operators in the region: oil and gas production facilities, mining, power supply networks;

you have previously built and maintained the network of the TETRA standard for operational production networks and the desire make the most of it "to capitalize", organized on the same wireless IPC system . At the same time, the network infrastructure (base stations, etc.) can be of any vendor.

a high degree of reliability of the independent system (in this case, it is its own) with guaranteed delivery of the management team is required: facilities of particularly dangerous production, oil production facilities, transportation and processing of oil products, traffic management systems, local and regional emergency warning systems;

upgrade the existing system of automated process control systems due to the need to provide more bandwidth through the digitization of radio technology, as well as the need to reduce the specific capital and operating costs by eliminating the laying of cables over long distances;

The solution based on the digital standard TETRA, will allow to receive telemetry data from automation objects and quickly manage them, process data in a SCADA system (system of aggregation, processing and visualization of data on the screen). There is a possibility of consecutive transfer of the existing telemetry systems on the basis of "zoo" technologies, including outdated analog, on the uniform technology of digital radio access TETRA. Additionally, you get your own digital wireless data and voice network.

One of the advantages of this technology is the availability of its own radio frequency resource in the range of 420 MHz for any legal entity and individual entrepreneur for the organization of its own infrastructure of IPC system (own base stations and user terminals).

The composition of the wireless IPC system:

1. SCADA - Schneider Electric «Wonderware InTouch», or other similar system of aggregation, processing and visualization of data, control and automation signals.

2. Database system «TETRACOM» - the SW pacкage, developed by TISSCOM, containing:
«SDS-server» SW, providing communication and SDS messaging with TetraFlex system;

MySQL database, containing structured directories and tables of IPC objects, information table for SCADA system about the status of IPC system parameters, table of radiocontrollers parameters enquires;

External database configurator – the instrument for creation and visualization of directories and tables of IPC objects.

3. TetraFlex system – existing TETRA radio network for voice and data transmission.

4. Control units for industrial automation TETRA – the units, produced by TISSCOM or uses these units, having in-built TW1m radiomodem from Airbus. Radiocontrollers send the information in event-driven mode and handle the incoming requests (control commands and other).

The construction of a fully functional system is possible in the configuration from one base station. The radius of radio coverage of one base station can be up to 53 km, depending on the height and terrain. The maximum number of connected radio controllers to one BS - up to 10 000 PCs. To cover large areas, the organization of systems in large cities, complex terrain, requires a larger number of BS.

TISSCOM has sufficient experience in designing, construction and operation of networks of TETRA standard. Some of the projects are reflected in the Portfolio(Works) section of the site. For the organization of the process control system of production and transportation of oil, to date, built and operated TETRA network covering almost half of the territory of the Republic of Tatarstan, it is about 30 000 sq. km of rugged terrain with difficult relief and with more than 50 base stations.
