Abstract
A position monitoring and control system comprises a pulse generating means (1), in conjunction with A control means (2) consisting of a micro control unit (MCU) (5), and input output unit (IOU) (6), to monitor the relative position of a door during it's operating cycle as well as communicate with other doors equipped with said system or a host computer (PC) for multi-door networking applications (Fig. 5). Said system is then capable of automatically compensating for various mechanical wear associated with the general operation of a door as well as eliminate the contact lag associated with standard mechanical type limit switches generally used for door control applications.
Said system also monitors for a zero motion condition and automatically disconnects the drive mechanism if zero motion occurs. Said system uses an on board user interface (7) and display (8) to allow the user too easily modify application specific parameters.

Description
DOOR CONTROL AND MONITORING SYSTEM
FIELD OF THE INVENTION:
This invention generally relates to the control of industrial garage doors or barners. More particularly, the invention relates to the control and monitoring of high-speed industrial roll up doors.
BACKGROUND OF THE INVENTION:
It is common in devices used in the control of industrial garage doors or barriers that the control means consists of the following elements. 1) A limiting device containing standard mechanical type limit switches and a screw driven slider setup attached to the doors drive mechanism to determine the limit of door travel during the opening or closing cycles of door operation. 2) A control panel containing electromechanical relays inter-linked to perform the required control logic such as time delays, sensor or push-button input control and drive mechanism control.
In some cases a programmable logic controller "PLC" may be used to perform the logic requirements. In the case of electromechanical relay logic, the components are bulky, prone to rapid wear, and in most cases expensive. The enclosure required to house this type of relay logic is quite large and can cause difficulties during the installation process where space may be limited. This type of logic setup does not readily lend itself to modifications in system requirements making hardware additions and user modifications difficult and expensive. In the case where a PLC is used, enclosure requirements are reduced; however special programming knowledge, software and equipment are required to perform any type of modifications. These requirements also make hardware additions and user modifications difficult and expensive.
In both cases the limiting device used poses a multitude of problems. The standard mechanical type limit switches associated with these limiting devices are prone to rapid distortion and wear requiring constant and costly re-adjustment or replacement.
The contact lag associated with this type of mechanical limit switch can cause a door to not complete its required distance of travel. The decreased size of the remaining opening can cause a collision between the object passing through the door and the door itself. A collision of this type can be very costly in repairs and in some instance can result in personal injury.
It is common in industrial garage door or barner applications for security features to be incorporated that limit the possibility of damage or injury due to door operation.
The security features commonly used in door control applications are often prone to rapid wear or mall function due to the environment in which they are used. The failure rate of such components is virtually unpredictable. If a door comes into contact with an immovable object, referred to as a zero motion condition, and these security features have failed, the drive mechanism for the door will continue to operate. This type of event can cause extensive and costly damage to both the object wedged in the door and to the door itself and in some cases can result in severe personal injury.
It is common in industrial garage door or barrier applications for the drive mechanism to incorporate frictional devices for torque transfer and breaking.
The constant mechanical wear associated with these drive components creates the necessity for chronic and costly re-adjustment and preventive maintenance schedules.
It is common in industrial garage door or barner applications for multiple doors to be installed in the same building. Having two opposing doors open simultaneously in a building can create a wind tunnel effect inside said building that can rapidly increase heating or air conditioning costs as well as cause discomfort to personnel.
SUMMARY OF THE INVENTION:
Said invention overcomes the limitations and problems associated with industrial garage door or barrier applications buy using an electronic pulse generating means attached to a motion surface of the door instead of the standard mechanical limiting devices commonly used, in conjunction with a purpose built microprocessor based control means capable of signal processing and analyses. Said system has been developed using a pulse generating means to precisely monitor a doors position thus eliminating the various problems caused by mechanical type limit switches. The ability to precisely monitor a door's position allows computation and automatic compensation of any variations in door travel characteristics due to the mechanical wear of drive components, thus decreasing the maintenance requirements of such components. Using such a pulse generating means allows a zero motion condition to be reliably detected by simply monitoring the positional changes of door travel while the drive mechanism is active and disconnecting the drive control if zero motion occurs. The advantage of this type of safety feature is that if it fails the door itself becomes inoperable. Using a purpose built microprocessor based control means renders inter door communication possible. This ability to communicate between doors is used to prevent two opposing doors from being open at the same time thus minimizing the potential for wind tunnel effects. A simple user interface and display are also incorporated into the control means to allow for easy user modifications to the system via easy to access menu selections. The control means, being purpose built for industrial garage door or barrier applications means that all known user requirements have been incorporated in such a device thus minimizing the time and cost of performing hardware additions and user modifications.
