With the spread of mass transit, public highway systems and mass produced automobiles has come a number of new problems for people in the industrialized world to confront. Pollution, the economics of fuel management, managing traffic congestion and the logistics of building roads are all large scale problems that most citizens leave to elected officials, but one problem all drivers have to deal with is finding parking. This has never been an easy task since the dawn of mass produced automobiles, but as more and more people have larger and larger cars, finding good parking can seem like Sisphysian ordeal. Managing a parking lot or garage, then, becomes a rather lucrative proposal, yet it is not always the easiest. Ensuring that paying customers can enter a parking lot or garage is of the utmost importance to managing such an enterprise, and one particular means of doing so is barrier gates. Accessing barrier gates is the task of a barrier gate reader.
A barrier gate, also known as a boom gate, is found at more than just parking facilities, according to EEAutomation. They also find heavy use as a mean to keep drivers from accessing drawbridges at inopportune times, as well as acting as a means to maintaining check points and entrances in restricted areas, be they the parking areas of a train station or a first entry point between public sectors and secure research facilities. They’re also the main means by which tollbooths are maintained, and anyone who’s used enough toll roads can tell you exactly what they look like. Some barrier gates are manually operated by a human being, but most are operated automatically. The means by which an automatic barrier gate is activated is the job of a barrier gate reader. A barrier gate reader generally scans for objects or signals that are programmed to activate it. A remote control device, familiar to anyone who uses an automatic garage door opener, can often open up a barrier gate. Some barrier gate readers are triggered by cards with magnetic strips programmed to open the gate, sometimes under specific conditions, such as the time of the day or the amount of money in a user’s account. Other barrier gate readers scan for radio frequency identification tags or reader RFID devices.
This is the preferred means by which “easy pass” toll booths are activated with a specialty device placed in the user’s car. When a car possessing such a device approaches a toll booth or similar region with a barrier gate reader, they approach slowly until the gate reader senses the RFID tag and activates the barrier gate to open it up so the car can continue forward. There are other means by which barrier gates can open up; loop detectors and push buttons come to mind, and there are a number of other specialty devices that can activate a barrier gate, but remote controls and RFID readers are the most common in the industrialized world. And, when you really need access to a road, the easier it is for the user to get past the barrier gate, the better.
