摘要： This invention relates to an improved digital weight measuring and computing apparatus with automatic zero correction which automatically corrects the zero indication of the apparatus.The weight measuring apparatus comprises a scale which employs a load cell and strain gauge to develop an analog voltage representing the weight on the scale. An analog-to-digital converter is then employed to change the analog voltage into a digital representation of the load on the scale. The digital converter provides a digital indication in addition to the digital indications employed to indicate the weight on the scale. The additional digital indication represents fractions of the least weight increment indicated of the weight on the scale. The additional digital indication is then employed to control the generation of a zero correction factor and this factor is then combined with the weight indications from the scale to indicate the correct weight of articles placed on the scale. The corrected weight in combination with the unit price of the article placed on the scale is then employed to compute the value of the article on the scale.

摘要： A digital load cell includes an EEPROM that is permanently attached to the counterforce along with a temperature sensor and a plurality of strain gages. The strain gages are mounted on the counterforce in the electrical configuration of a full wheatstone bridge. The EEPROM and bridge are connected to a flexible circuit that is detachably connectable in electrical communication with circuits including a processor and an analog-to-digital converter, which can be mounted permanently on a local circuit board physically separated from the EEPROM. The local circuit board operates in a manner so that the EEPROM can be programmed to store the calibration/correction factors that are to be applied by the processor to the digital weight signals from the analog-to-digital converter. The local circuit board is associated with, and alternatively can be removably attachable to, the counterforce.

摘要： Load shift compensation of a strain gage load cell is accomplished by connecting a pair of fixed resistors in series across the output of a bridge circuit incorporating the load cell strain gages. The junction point between the series resistors is established at a desired signal level by a digital to analog converter connected thereto or by a voltage divider network so that, in effect, a part of the resistance of the resistors required to achieve load shift compensation is made to shunt a pair of the strain gages in the bridge circuit. The required signal level may be established by positioning weights on the scale platter at different positions parallel to the longitudinal axis of the load cell beam and adjusting the signal level at the junction point between the shunting resistors until a desired degree of compensation is achieved. The digital correction value required at the input of the digital to analog converter to achieve compensation is stored in the memory of the scale computer.

摘要： A weighing in motion (WIM) apparatus and method in which scale platforms are provided exhibiting a high rigidity selected to achieve a relatively high natural frequency response characteristic. These platforms are combined with instrumentation wherein load cell derived signal outputs are digitized at a conversion or sampling rate effective to permit an identification of amplitude data correlative to vehicle weight. In particular, the sampling rate is selected so as to isolate and detect peak amplitude output of the system which is directly correlatable to truck weight. The invention derives from a recognition that, during the dynamics of movement of a vehicle such as a truck over the rigid scale platform structures, there occurs a decoupling of the mass of the truck from the scale permitting its response to the weight of the truck without significant loss of natural frequency bandwidth. Through the use of a high speed processor such as a digital signal processor (DSP) essentially real time weight evaluations can be carried out.

摘要： A scale is disclosed which includes a digital display unit for conveying information. A display verification method and system are employed for determining whether a plurality of information conveying segments forming the indicators of the display unit are properly conveying information. Individual segments of the display unit are operated under control of a microprocessor. Segment status determining circuitry determines the operative status of each of the segments by sequentially monitoring a voltage drop indicative of the current passing through an LED comprising that segment. The status determining circuitry produces status information which is stored in the microprocessor memory and compared with data indicative of the information the display should convey if it is properly functioning. If the comparison indicates that one of the segments is not properly conveying the information, warning messages are displayed which indicate maintenance procedures are required. If all segments are correctly displaying information, the verification procedure is repeated.

摘要： The invention relates to a scale system which employs a microcomputer forming an integral part of the analog to digital conversion means in which the microcomputer controls the sequence of operations for performing the conversion, accumulates and stores digital data derived during the conversion of the analog signal and combines and processes that data to provide the digital output data resulting from the conversion, all in addition to performing other scale functions. The invention relates to an improved multicapacity weighing and computing digital scale having a triple slope analog-to-digital conversion means. The analog weight signal is integrated for a time interval which is fixed for a given scale capacity range which would generate substantially the same integrator output level in response to a full capacity weight signal for the selected scale capacity as would be generated by a full capacity weight for all other scale capacities. In accordance with the invention, the time interval during which the first reference DC source is integrated is extended beyond the detection of the crossover of the integrator output with its reference level. The invention also provides an improved weight filtering arrangement which enables the full advantage of the improved converter to be obtained. The invention further provides for the tracking of the net zero indication by modification of the stored tare weight data by a predetermined amount to decrease the absolute value of the net weight in response to the net weight being within a preselected weight range.
