Description
ток потреблени контролируемого блока табло 7, например блока лампочек, равен току одной лампочки, и иа выходе индикатора 5 изменени потреблени питани , подключенного своим входом к источнику питани 6, сигнал отсутствует, так как нет изменени тока питани . Если цепь ламночки иеисправна, то при попадании луча на фоторезистор, соответствующий этой лампочке, произойдет скачкообразное измененне тока питани и индикатор изменени этого тока пошлет сигнал на вход дешифратора 4, что заставит его отпечатать на ленте тот номер, который в этот момент показывает счетчик 3, т. е. пор дковый номер неисправной цепи табло.The current consumption of the monitored board unit 7, for example, the lamp unit, is equal to the current of one light bulb, and the output of the power consumption change indicator 5, connected by its input to the power source 6, is absent because there is no change in the power supply current. If the light circuit is faulty, then when the beam hits the photoresistor corresponding to this light, a power supply current changes abruptly and the change indicator of this current will send a signal to the input of the decoder 4, which will cause it to print on the tape the number that i.e., the serial number of the failed circuit board.
Таким образом, предлагаемый автоматический регистратор номера неисправной цепи в результате последовательного онроса всехThus, the proposed automatic registrar of the number of the faulty circuit as a result of the sequential onros of all
чеек табло отпечатает на ленте номера ieиснравных цепей.the cells of the scoreboard will print on the tape the numbers of i-equal chains.
Предмет изобретени Subject invention
Автоматический регистратор номера неисправной цепи табло, содержаш,ий источник питани , индикатор и схему унравлени , отличающийс тем, что, с целью новышени оперативности и надежности обнаружени места повреждени табло, схема управлени содержит reiiepaTOp командиых сигналов, счетчик переключений и дешифратор, причем генератор командных сигналов соединен со входомThe automatic recorder of the number of the malfunctioning circuit of the board, containing the power source, the indicator and the control circuit, characterized in that, in order to improve the efficiency and reliability of detecting the site of damage to the board, the control circuit contains a reiiepaTOp command signal, a switch counter and a decoder, the command signal generator connected to the entrance
счетчика числа переключений, выход которого соединен с одним из входов дешифратора, другой вход которого электрически св зан с индикатором.a number of switches, the output of which is connected to one of the inputs of the decoder, the other input of which is electrically connected with the indicator.
