Description

one

The invention relates to the field of experimental cerium flziki - and can be applied in systems and installations of nuclear instrumentation, where it is necessary to register processes from sensors with analog OR pulsed; M output.

Multichannel radiometric devices are known that contain detectors, a collection circuit, a scaler, an overflow trigger, a matching circuit, a matrix, a recording matrix, a recording unit, and an arithmetic and arithmetic unit.

The aim of the invention is to improve the speed and the contraction of equipment.

This is (achieved by the fact that the sensors with analog outputs are connected to the counters via serially connected switchboards, switch-switches, linear circuit OR or converter. The sensor with impulse outputs are connected to the Icc counter through the switch and logical circuit OR, the output of the counter through the transmission circuit is connected to the arithmetic unit and, through the block of threshold settings, to the prohibition circuit and the memory elements. The distributor is connected to the switchboard1 of the channels, the switchboard group, the numberspace, the element :. E memory allocator load circuit and transmission circuit ban output circuit through prohibition subdiagram recorder; pazona, load distributor and the encoder coupled to Lomer zapominayupgim device.

The drawing shows the block diagram of the described device.

It contains sensors / with analog output, KOiiMyraTOp 2 channels, switch-on switches 3, linear circuit OR 4, converter 5, counter 6, sensors 7 with I1M1pulsnymi outputs, switch groups 8, logic circuit OR 9, distributor 10, circuit / / transmission , arithmetic unit 12, memory J3, number 14 encoder, block 15 threshold settings, elements of parameter 16, indicator 17, prohibition circuit 18, registrar 19 subbands, load distributor 20.

The described device works as follows. Sensors / with analog output convert the measured physical parameters into electrical signals into an analog IBO, M form (current or voltage). The sensor outputs by the 2 channel switch are polled sequentially. At the output of the key-interrupters 3, single pulses are generated, and the amplitude of them is proportional to the value of the measured signals. From the outputs of all the key switches, pulse signals are successively fed to a linear circuit "OR 4 and to a converter 5, which

converts the amplitude of the impulses sent to the input into a train of pulses, the number of which is proportional to the amplitude of the input pulse (the pulse. This number is recorded in counter 6.

Simultaneously, sensors 7 with pulse-and outputs-convert energy, ioiziruyuschuyu Radiation Number, into statistical sequences AND, m1puls4v, which are supplied through a switchboard of group 8 and a logical scheme, OR 9 and a counter 6. The order of processing information from datsh with analog and vmulse, outputs, mi, are determined by distributor 10.

The digital code corresponding to the values measured by the sensors with analog outputs is sent to the arithmetic unit 12 through the resolution of the distributor through the transmission circuit AND to the memory device 13. The sampling of the optional sensor number (. Channel) is carried out the help of the encoder number 14, IB of which in the corresponding code of the form, the addresses of the numerical cells of the memory device are reconciled.

From counter 6, the measured values of a-tax values, in the digital code of the FROV01 code, are supplied to a block of 15 threshold settings, where the measured values are compared with predetermined threshold values. Excess signals, at the command of the distributor, are allocated to the corresponding memory elements 16 and to the indicator 17, & as a result, kayals are displayed, in which they pierced above threshold settings.

The total statistical sequence of pulses corresponding to a definite rpyinne channel is recorded in the counter and compared with threshold settings corresponding to} 1M: the count rate of the end of the sub-band. When these settings are exceeded, a prohibition scheme 18 is given a signal that is passed to the recorder 19 sub-regions according to permission from the distributor. In the perncTipaTOpe subbands for a given time period of the measurement, the number is recorded by the range of the measured number of each group of sensors.

These signals are sent to the distributor.

20, to which signals of transmission are simultaneously transmitted on a -pulse sequence from a group to a strictly defined sequence in the range of the whole time from 1MBray. Moreover, the times of the Merbnis of each group, when the thresholds of the subbands are exceeded, are shifted relative to each other, and are reduced in magnitude by a factor of ten when the lower subzone goes up to the upper one. TaiKnai simultaneously, the integral load of the storage device is reduced to the value of the integral load of the group.

As a result, upon the arrival of any impulse, from sensors with a pulse output, a signal is sent to the number emitter, which forms the address of the corresponding sensor.

A previously recorded information message is selected from the storage device and a unit is added to the arithmetical device. The new number is then written to the memory reminder.
