New ProSense fork sensors (slot sensors or "U" sensors) are designed for easy installation; the rugged metal one-piece construction assures constant alignment. These high-resolution fork sensors feature glass optics, selectable light on/dark on operation, adjustable sensitivity potentiometers, high switching frequencies, and are fitted with M8 connectors with 360-degree viewable LED indicators. PNP and NPN logic versions are available. Starting at $86.00, the visible red light fork sensors feature easy setup and have sensing ranges from 5mm to 220mm. Starting at $137.00, the laser fork sensors feature a Class 1 laser to detect small objects, have sensing ranges from 30mm to 120mm; models are available for transparent objects. ProSense fork sensors are IP67-rated, have cULus approval and are CE, RoHs and REACH compliant.

To reduce traffic and pollution, many cities are improving public transportation to promote bus travel. Offering a great passenger experience is critical to encourage the public to adopt buses as their main means of transport.
Built-in computers that connect wirelessly to the internet are a standard feature of a new generation of intelligent buses. High-performance computers are required for this job, because they must be able to handle multiple tasks at the same time, including control, data collection, monitoring, and data transmission. The automated doors are controlled by the computer through DI/DO interfaces. Passengers are automatically counted as they enter and leave the bus, and passenger flow data can be stored for later analysis. The onboard IP cameras send video to the computer for storage and for real time display on the driver’s panel, to assure passengers’ safety. The card reader processes the ticket info, calculates the price, updates the card, and sends the information back to the control center. All these jobs can now be handled by a palm-size industrial computer. It may appear that these functions and the data gathered only affect the individual bus and its passengers, but in fact, wider benefits are possible by linking the bus wirelessly to a larger network.
The wireless computer records GPS data and sends its current location to the control center. Meanwhile, passenger data can be used to let commuters waiting at bus stops know when there are vacant seats on upcoming buses. As well as analyzing the information gathered by the computer to optimize bus scheduling, it can also be provided immediately to potential passengers through real-time bus information displays at bus stops or and smart phone apps. When this information can be shared in real time, improving the bus passenger’s experience becomes easier.
Because space is limited in a bus, a very compact embedded system is a must. In addition, the system needs to be shock and vibration-resistant to provide reliable live voice and data communication to the remote control center. A variety of wireless connection modes also helps reduce costs, as a bus has to travel all over the city, and multiple wireless options make it easier to connect to variety of different devices in different situations.

When the monitoring system along a key harbor corridor in a major American city needed updating, the system manager decided to use existing copper wiring to transmit data over significantly longer distances. As this project needed to integrate more systems into one network, serial networks were no longer sufficient to support the expanded network, which is why an industrial Ethernet technology over copper wires via a DSL was required to support more bandwidth over longer distances. In addition, VPN connections and firewall protection were required to ensure network safety and data integrity. Read More
