Abstract

Abstract ABSTRACT OF THE DISCLOSURE A range controller for continuously monitoring the position of the boom of heavy machinery, is disclosed. The range controller comprises position sensors mounted on the boom and on the machinery for continuously detecting the position of the boom with respect to a reference, control switches located in the cabin of the machinery for permitting the operator to set the position limits of the boom, a central control circuit mounted on the machinery and comprising a micro-processor circuit adapted for connection to the sensors and to the control switches and memory devices for registering the position of the boom as well as the position limits set by the operator and for continuously comparing the actual position of the boom with the position limits, and indicators located in the cabin of the machinery and responsive to such micro-processor circuit for warning the operator and, preferably blocking the operation of the boom when a position limit is reached.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 148 words
A range controller for continuously monitoring the position of the boom of heavy machinery having a cabin for an operator, comprising: a) position sensors, mounted on the boom and on the machinery, for continuously detecting the spatial position of the boom with respect to a reference; b) control switches, located in said cabin, for permitting the operator to set the position limits of the boom; c) a central control circuit, mounted on the machinery and comprising: a micro-processor circuit, adapted for connection to the position sensors and to the control switches, and memory devices, for registering the position of the boom as well as the position limits set by the operator, and for continuously comparing the actual position of the boom with said position limits; and d) indicators, located in said cabin and responsive to said micro-processor circuit, for warning the operator when a position limit is reached.
Claim 2
Dependent Claim 148 words
A range controller for continuously monitoring the position of the boom of heavy machinery having a cabin for an operator, comprising: a) position sensors, mounted on the boom and on the machinery, for continuously detecting the spatial position of the boom with respect to a reference; b) control switches, located in said cabin, for permitting the operator to set the position limits of the boom; c) a central control circuit, mounted on the machinery and comprising: a micro-processor circuit, adapted for connection to the position sensors and to the control switches, and memory devices, for registering the position of the boom as well as the position limits set by the operator, and for continuously comparing the actual position of the boom with said position limits; and d) indicators, located in said cabin and responsive to said micro-processor circuit, for warning the operator when a position limit is reached.
Claim 3
Dependent Claim 30 words
A range controller as defined in claim 1, further comprising A blocking system, responsive to the micro-processor for blocking the operation of the boom when a position limit is reached.
Claim 4
Dependent Claim 62 words
A range controller as defined in claim 2, further comprising a main relay, for operating said blocking system, said main relay being electrically energized during normal operation of the machine to release the blocking system so that, if there is malfunction such as a power failure, or a break in a wire, the main relay is released to operate said blocking system.
Claim 5
Dependent Claim 37 words
A range controller as defined in claim 3, further comprising additional relays, for reversing the operation of the boom when said main relay is released, so as to ensure safe stopping of the movement of the boom.
Claim 6
Dependent Claim 28 words
A range controller as defined in claim 3 or 4, wherein said relays are located in a control system which assists the main power system of said boom.
Claim 7
Dependent Claim 115 words
A range controller as defined in claim 1, wherein the position sensors comprise a vertical position sensor, capable of detecting and translating the angle of the boom relative to the horizontal into an electronic signal readable by the micro-processor circuit, and a horizon-tal position sensor, capable of sensing the relative position of the machine with respect to the horizontal and of translating such position into an electronic signal readable by the micro-processor circuit, said vertical and horizontal position sensors permitting the micro-processor circuit to make a correlation of the vertical and horizontal movements of the boom in a two-dimensional plane with respect to said reference, to register the limit and current position of the boom.
Claim 8
Dependent Claim 27 words
A range controller as defined in claim 1, 2 or 3, wherein said indicators and said control switches are located in a control box in said cabin.
Claim 9
Dependent Claim 46 words
A range control as defined in claim 6, further comprising a telescopic position sensor, for use when said machinery is a telescopic crane, and wherein said telescopic sensor is adapted to translate the boom length differential position into an electronic signal readable by the micro-processor circuit.
Claim 10
Dependent Claim 23 words
A range controller as defined in claim 8, further comprising A displacement sensor, to detect any displacement of the machinery on the ground.
Claim 11
Dependent Claim 28 words
A range controller as defined in cliam 9, further comprising exteror indicators, mounted on the top of the machinery for warning people outside of said cabin against danger.
Claim 12
Dependent Claim 28 words
A range controller as defined in cliam 9, further comprising exteror indicators, mounted on the top of the machinery for warning people outside of said cabin against danger.
Claim 13
Dependent Claim 87 words
A range controller as defined in claim 10, wherein said con-trol circuit further comprises an input multi-plexer circuit, connected to said position and displacement sensors and to said control switches, to channel all input data from the sensors and the control switches to the micro-processor circuit, and an output circuit, connected to the indicators located in said cabin, to the exterior indicators and to the blocking system, to latch output data and drive the indicators and the blocking system following the data provided by the micro-processor circuit.
Claim 14
Dependent Claim 37 words
A range controller as defined in claim 11, wherein all input data fed to the micro-processor is coded, and further comprising a failure detector circuit, for detecting an erroneous code or a failure of the micro-processor circuit.
Claim 15
Dependent Claim 44 words
A range controller as defined in claim 11, further comprising data switches, connected to the input multi-plexer circuit, and programmed At the time of installation of the controller, to insert in the micro-processor circuit data corresponding to the nature of the specific machinery used.
Claim 16
Dependent Claim 62 words
A range controller as defined in claim 13, wherein said data switches allow the micro-processor circuit to determine the limits of a certain buffer zone from the position limits set by the operator, and wherein said indicators include means to warn the operator of the approach of a limit in order to allow him to react accordingly before the limit is reached.
Claim 17
Dependent Claim 37 words
A range controller as defined in cliam 1, wherein a carriage is movably mounted on the boom, and wherein a position sensor is mounted on said carriage for detecting the displacement of the carriage on the boom.
