2. Description of the Related Art

Gate security access control has recently been given increased attention as it provides basic safety protection to the establishments. The security of vehicular movement is the major concern in any of the establishments such as Office, industrial units, housing society etc.

A security barrier or bollard may be used for resisting an unauthorized passage of a vehicle such as a two-wheeler or a car or truck. Such barriers typically comprise housing with a barrier member mounted to it. The housing is typically cast into concrete foundations below ground level. The bather member is arranged to be retractable so that it can be stowed within the housing to allow the vehicle to pass, or deployed to a working position above ground level to prevent or inhibit the vehicle to pass. In the deployed position the barrier member is required to be sufficiently high above ground level to prevent or inhibit the vehicle from passing.

Security barriers are typically provided in two categories. The first category is a high security barrier, or anti-terrorist barrier, that is intended to prevent a vehicle from passing. Such a barrier is robustly constructed and is typically about 915 mm above ground level. A high security barrier might be used at a road entrance to an airport or an official building, such as a Government building, and is typically able to withstand a crash impact from a car or truck. The second category of security barrier might be used at a home or work premises to safeguard a car parking space or driveway from being used by another vehicle. Such barriers are relatively less robustly constructed, and may extend up to one meter above ground level.

There are several types of security barriers reported in the art, the particularly interested one's include U.S. Pat. No. 8,979,419, which discloses a security barrier having a support and a barrier member movable relative to the support between a stowed position and a deployed position, the support having an uppermost part for positioning substantially at ground level, the barrier member being pivotally mounted relative to the support such that a pivot axis of the barrier member is above the uppermost part, wherein the pivot axis is a fixed axis through the entire movement of the barrier member between the stowed position and the deployed position, such that the barrier member only follows the path of a circle between the stowed position and the deployed position.

US20150139726 discloses a barrier system for alternately shutting and opening the vehicle entrance or pedestrian entrance of two lines or transport paths which cross one another and of which one is at least twice as wide as the other. On the four corners of the lines which cross one another, in each case one barrier system with in each case one barrier boom which can be pivoted horizontally out of the vehicle entrance of one line into the vehicle entrance of the other line is installed. Two of the barrier systems which lie diagonally opposite to one another and have in each case one barrier boom which can be folded lengthwise from an elongate position. The two other barrier systems which lie diagonally opposite to one another have in each case one conventional barrier boom which is rigid over its entire length.

U.S. Pat. No. 5,476,338 discloses a bollard type security barrier apparatus for use in controlling ingress and egress to controlled areas. The apparatus is of simple design, easily installed and includes a remotely operated positive drive mechanism for raising and lowering the bollard which is telescopically mounted within a sealed casing adapted to be mounted beneath the ground. The drive mechanism and the bollard are readily removable from the subterranean casing for repair or replacement; and, for certain applications, the upper portion of the bollard can be illuminated.

US20140077927 discloses a method for controlling a gate using an AIE system is disclosed herein. The method can comprise receiving identification data from an identification card using an identification card reader mounted to a first surface of an enclosure and receiving biometric data from a biometric data reader mounted to a first surface of an enclosure. The method can further comprise searching for a profile within a memory that comprises an identification data and biometric data, as well as wirelessly sending an instruction to open a gate, if the profile is authorized.

US20050110610 discloses a system for providing stand-off biometric verification of a driver of a vehicle at a control gate while the vehicle is moving, including a pre-verification system and post-verification systems. The pre-verification system is installed before an entrance of a facility and comprises an RFID vehicle tag reader, an RFID personal tag reader and a facial detection and recognition (verification) system. The RFID vehicle tag reader scans and reads an ID from an RFID vehicle tag of the vehicle that is trying to pass through the gate. The RFID personal tag reader reads an ID from an RFID personal tag carried by personnel who are driving in the vehicle. The facial detection and verification system scans and reads facial images for the driver. The post-verification system is installed on at least one of an entrance and an exit for post-verification to ensure that the vehicle that enters the entrance or leaves from the exit is the one that has been verified/denied at the control gate. In one embodiment, the post-verification system comprises an RFID personal tag reader and an RFID vehicle tag reader. In another embodiment, the post-verification system also comprises a facial detection and recognition system.

None of the prior art references deal with efficient, automatic and cost-effective security systems or equipment for selectively shutting and opening the vehicle entrance or exit or passage ways and there exists drawbacks in the prior art for the security concerns and also the prior art systems are more complex and consume more electrical power which is not eco-friendly. Since the bollard systems discussed above are based on hydraulics, if there is a leak, then the entire area is spilled with oil. In hydraulics, an electric motor is used to rotate the pump and in turn pumps the oil to the cylinders through control valves thus it uses a secondary energy. In electromechanical equipment, a direct motor is used to drive the equipment and balancing technology makes load on drive shaft almost nil, thus we reduce power requirement.

Therefore, the present invention's aim is to overcome the drawbacks of the prior art systems by developing the simple, efficient, automatic and cost-effective security systems or equipment[s] with manual override for selectively shutting and opening the vehicle entrance or exit which consume minimum electricity and are eco-friendly.
