SFMTA Examination of safety regulations, tunnel ventilation

What is a tunnel with a safety ventilation without a serious test of the same? Nothing to be exact.
Inframatic changes that by testing the safety-relevant aggregates.
Fire ventilation, using ultrasonic measuring devices in a cross arrangement, to test whether the air speed achieves sufficient performance even in the event of an incident. At the same time, we tested airflow visually, using smoke grenades.
These show “mercilessly” where any defects are.
In the case of the extension of the San Francisco Metro from Union Square to China Town, no doubt about it. The following tests were carried out:

San Francisco metro station “Union square”
  • Ultrasonic cross-measurements of the airspeed across the whole tunnel section, 4 pcs. at the same time
  • Smoke grenade test to make visible where the airflow goes
  • Door force measurements to comply with regulations
  • Noise measurements
  • Anemometer measurements

Highpower EV-Charging

500 KW, HPC DC connector

We plan and build complete solutions for extensive electric charging stations and infrastructures in the field of electric mobility. We rely on the most modern technologies. Above all, the high-performance charging technology (HPC, high power charging). This enables direct current charges of up to 500 kilowatts. This means that an electric vehicle is 90% charged within 5-10 minutes (depending on the vehicle type and approved charging capacity).

Our services:

  • Overall planning of the charging infrastructure
  • Energy and power calculations
  • Network planning and execution for remote monitoring
  • Hardware planning of the charging stations
  • Software development of the charging controller
  • Software development of the control system technology
  • Software and hardware for EFT / POS
  • Commissioning of the plants

Our services

Inframatic – as the name suggests – is your partner for the expansion and renewal of infrastructure projects. We are a globally active company in the field of traffic safety, in particular the control and monitoring of motorway tunnels, rail tunnels, bridges and airports. We act either as a general planner and / or as an executing company. We provide our services in the following areas:

  • Motorway tunnels and highways
  • Railway tunnels
  • Subways
  • Bridges
  • Airports
  • General infrastructure projects

We basically process all technical systems that require the infrastructure mentioned above. These are essentially:

  • Tunnel ventilation systems
  • Video surveillance systems
  • Lighting systems
  • Energy supply systems
  • High and low voltage distribution systems
  • Fire alarm systems
  • Signaling systems
  • Traffic control technology
  • Network technology
  • Control technology

Our company is a planning and execution office for integral tunnel safety and control technology. We rely on the latest technologies without being dependent on a single provider. All systems used are established and have been able to prove themselves over decades. We not only rely on openness and independence in terms of hardware, but also rely on open-source components and frameworks wherever possible for software. Above all with the visualization and the control systems. These are developed by us using the latest HTML5 technology, without sacrificing security. All connections are encrypted and monitored. This applies not only to the software, but also to the networks. Because, as is well known, there are also many networks or network protocols on the market. Here, too, you can choose between proprietary or open protocols. We prefer the latter.
On the planning side, we develop systems from the pre-design phase to Construction Administration (CA). When executing the systems, we deliver all documents such as the specification of services and performance descriptions, all electrical drawings such as principal diagrams, electrical diagrams, control cabinet dispositions, cabling plans, electrical performance calculations, etc. Function descriptions and program flow charts are also part of our services, as well as the entire commissioning, tests of the systems and their decreases.
Our software is developed and documented in a structured manner. The control software includes all functions necessary to ensure safe operation of the infrastructure. Our focus is on the greatest possible degree of automation so that maintenance is burdened with as little manual intervention as possible. In addition, our focus is also on energy efficiency. Because our systems combine safety with the lowest possible energy consumption. For example, it makes no sense to run a tunnel ventilation system when there is little to no traffic. In order to make this possible, we use the sensors built into the tunnel and use all the functionality of the individual systems integrally instead of just using individual sensors assigned to the systems. This means that we use the sensors intelligently across all systems.
The biggest highlight of our systems is – in addition to the intelligent control functions – the openly programmed visualization. Instead of relying on commercial products, we develop the control systems completely ourselves. This has several advantages. First, we save license fees from the commercial provider. For you as the end customer, this means that the system becomes cheaper. Second, we never come across any limiting requirements. This means that you get exactly the system you want. The expression “doesn’t work, doesn’t exist” hits the bull’s eye with us. The visualization is completely developed in HTML5. For you this means that you can open the system pictures with any browser. Plugins are not needed anywhere. We also do not have limited access, as is common with commercial control systems. It does not matter whether a single user or a hundred open the browser window and access the system. And best of all, all of this is included in the scope of delivery. Thanks to the open programming in HTML5, adjustments are made in no time at all. With the appropriate specialist knowledge, such adjustments could also be carried out directly by the end customer himself. We call this visualization «Infraview». But if you prefer commercial products, that’s no problem either. Our employees are familiar with many commercial products. WinCC o.a., Cimplicity, Wonderware, Simatic WinCC. We could expand this list at will.

Control technology / Supervising

Local and higher-level control systems are required so that all systems can be operated and observed or monitored. Thanks to these systems, it is possible to display the complexity clearly and make it usable for a person. Thanks to data recording, it is then also possible to improve the systems in operation where necessary. Another very important point is the alerting in the event of pending malfunctions of individual parts of the system.

Network

A network is required so that all systems can communicate with each other and thus transmit reflexes, and also send data to a control system. These networks are naturally very large and extend over great distances.

Networks are the arteries of modern infrastructure systems. Measured values and states must be transferred between the controls and the control system and also between them. Due to the large distances involved, these networks are usually formed with glass fibers. We plan and lay out the networks, from the lowest to the highest level (OSI layer 1 – 7). If necessary, we also develop our own network protocols.

Signaling systems

The signaling systems dynamically indicate the applicable speed limit according to the volume of traffic. In addition, they are also used for dynamic traffic control and display in the event of a traffic jam, accident or other impairment of one or more lanes.

Video surveillance systems

Video surveillance in motorway tunnels is also becoming increasingly important. In the past, this was simply used for visual monitoring of the traffic inside the tubes. Thanks to increasing digitization, there are many more possibilities today. Above all the so-called automatic event detection. Based on the video images from the cameras, this recognizes whether there is any danger inside or outside the tunnel. The event detection detects whether a traffic jam is or will arise, whether an accident has occurred or whether a fire has broken out. Objects on the road are also detected so that road users can be warned at an early stage. As a result, video surveillance is also used more and more frequently for fire detection.
