Description

Изобретение относитс  к весоизмерительной технике. Известны автоматические устройства дл  измерени  веса и скорости транспортных ед,иниц , суммарной нагрузки на дорожное покрытие и дл  счета числа транспортных единиц с разделением на весовые и скоростные категории , содержащие грузоприемный узел, внхретоковый преобразователь, счетно-решающий , измерительный и регистрирующий блоки Однако эти устройства не обеспечивают требуемой точности. В предлагаемом устройстве грузоприемный узел выполнен в виде металлической плиты, щарнирно вмонтированной одним концом по всей щирине р да в дорожное покрытие, а другим концом соединенной с демпфером и .д элементом и установленной с зазором к внхретоковому преобразователю. На чертеже показана схема устройства. Грузоприемный узел 1 содержит металлическую плиту 2, с помощью шарнира 3 вмонтированную по всей ширине р да в дорожное покрытие, демпфер 4 с дросселем 5, упругий элемент 6, вихретоковый преобразователь 7, кронштейн 8 и бетонный короб 9. В измерительный блок 10 вход т генератор // синусоидальных колебаний, усилитель 12, выпр митель 13 и фазовращатель 14. Счетно-решающий блок 15 состоит из дифференцирующего элемента 16, сумматора 17, делител  18 и логических элементов 19, 20 и 2/. Блок 22 регистрации содержит самопищущие приборы 23 VI 24 и счетчики 25, 26 и 27 импульсов. Вихретоковый преобразователь 7 помещен под плиту 2 с некоторым воздущным зазором . Упругий элемепт 6 обеспечивает велнчину рабочего хода плиты и не позвол ет плите опуститьс  ниже уровн  дорожного покрыти . Пр.и наезде оси транснортной единицы на плиту 2 (о.1.новременный наезд двух осей при этом исключен выбором щирины плиты вдоль оси .тороги) нз.мен етс  воздушный зазор преобразовател  7, подключенного к генератору // измерительного блока W. Выходной сигнал преобразовател  7 после усилител  12 подаетс  на вход выпр мител  13. Одновременно напр жение от генератора // поступает на вход фазовращател  14, выходное папр жение которого используетс  в качестве опорного дл  выпр мител  13. Фазовый угол опорного напр жен1:  фазовращател  14 выбираетс  из соображений исключени  вли ни  сезонных колебаний температуры на результаты измерени .This invention relates to a weight measuring technique. Automatic devices are known for measuring the weight and speed of transport units, units, the total load on the pavement, and for counting the number of transport units divided into weight and speed categories containing a load-receiving unit, an intra-current transducer, counting, measuring, and recording units. However, these devices do not provide the required accuracy. In the proposed device, the load-receiving unit is made in the form of a metal plate, hinged at one end across the entire width of the row into the road surface, and at the other end connected to the damper and the element and installed with a gap to the intracurrent transducer. The drawing shows a diagram of the device. The load-receiving unit 1 contains a metal plate 2, using a hinge 3 mounted over the entire width of the row into the pavement, a damper 4 with a choke 5, an elastic element 6, an eddy current transducer 7, a bracket 8 and a concrete box 9. The measuring unit 10 includes a generator // sinusoidal oscillations, amplifier 12, rectifier 13 and phase shifter 14. Counter-calculating unit 15 consists of differentiating element 16, adder 17, divider 18 and logic elements 19, 20 and 2 /. The registration unit 22 contains self-searching devices 23 VI 24 and counters 25, 26 and 27 pulses. Eddy current transducer 7 is placed under plate 2 with some air gap. Resilient elemept 6 ensures the wellness of the working stroke of the slab and does not allow the slab to descend below the level of the road surface. The axis of the trans-unit unit on plate 2 (o.1. Simultaneous hitting of two axes is excluded by selecting the plate width along the axis of the turn). The air gap of the converter 7 connected to the generator // of the measuring unit W is changed. The output signal Converter 7 after amplifier 12 is fed to the input of rectifier 13. At the same time, the voltage from the generator // is fed to the input of the phase shifter 14, the output junction of which is used as a reference for the rectifier 13. The phase angle of the reference voltage 1: the phase shifter 14 is selected from Images excluding the effect of seasonal temperature fluctuations on measurement results.
