Description

one

The invention relates to automation, in particular to pneumatic computing devices.

A device containing a pulse generator, a memory node whose output is connected to the device output channel, log-nodes for the number of input channels and an anti-log node, made in the form of a pulsating throttle connected to the capacitance and a key, is known.

This device has a complex structure.

The proposed device is devoid of this drawback due to the fact that the device has a multi-input switch and a switch connected to the switch whose INPUTS are connected to the outputs of the logarithmic nodes, and the output to the pulsating choke of the anti-logarithmic node.

FIG. I shows a diagram of a device with a switch in the form of a running temporary node; in fig. 2 is a diagram of a device with a switch built on prohibition elements; in fig. 3 is a diagram with one common logarithmic node.

The proposed device 1 contains p log-nodes 1, anti-log node 2 with a memory node 3 and switch 4 with switch 5, designed to

alternately connecting the logarithm nodes to the anti-logarithm 2 node after a specified time.

Each logarithmic node 1 contains a pulsating choke i, capacitance Fi, valve / Sl1 and reference element Y. The antilog module consists of a pulsating throttle RS., A tank Va and a valve Yes.

The output of node 2 is connected to node 3 of the memory. Switch 4 is connected to switch 5 and to node 3.

An oscillator 6 is common to all logarithm nodes and is connected to them via valves K.

The device works as follows.

In the initial state (signal P „« 0) switch 5 is in the position at which node 2 is connected to the first node 1, the supply pressure from switch 4 is applied to the element CU. Output signal / yi l l opens valve Ki, as a result of which pulses from the Pri generator start to flow to the pulsing choke R.

The clamps of the Ki of the other nodes 1 are closed, since the supply pressure has not been applied to their elements.

From tank Y, the gas is released through the choke Ri IB of the POI reference level line until the pressure in the tank FI is equal to Pzi. In this case, the signal Yau1'0 appears, and the arrival of the pulses Pri on the throttles i and a through the valve Ki cracks. At this point, in accordance with the STI equation with the aperiodic link (), the throttles i and Ra will pass tl pulses, defined by the equation: ii - logai where P ° 21 and P ° and -input signals counted from the PO Ь ai 7j level are constant time of the periodic link (JRi-Vi), expressed in the number of pulses. In the tank Va, the pressure P ° is equal to: p ° p; e-a (2) where P ° -P ° C is the pressure measured from the PO level, Ta is the time constant of the aperiodic link (: Ra-Va). Substituting (1) into (2), we obtain an expression defining the value of pressure P at the output of node 2: p; -p; f 7i / Ta const - adjustable exponent. Then, the switch 4 connects to node 2 a second node 1, to the reference element of which power is supplied. Upon completion of logarithm at the output of the node 2, the pressure Pl, Pl (P22lP ° 12f PS (PlilPn (R & P, etc.) is established. After connecting the last gth node 1 at the output of the node 2, the pressure Pt Jaz P {P21 / Pu f. Oooo7 J 7 then this pressure on the signal Rc from node 4 is transmitted to the output of the device as a signal J out. In the device of Fig. 2, the encircling device is implemented from the “Denied” logic elements, which reduces the calculation time, since switching to the next logarithm is executed immediately after the end of the log arithmetic, and not after a predetermined maximum logarithm time. Switch 5 consists of valves. The end signal of the current calculation cycle and the beginning of the next cycle are signaled by the signal Ruth of the last m-20-ro node 1. In the particular case when all ratios (Pli / Pii) have the same exponent C, the nodes 1 are identical, and since they operate alternately, it is possible to have one common node 1 to which the necessary pairs of inputs PII, Pc1 are alternately connected. A diagram of such a device is shown “and FIG. 3. It contains a switch 5, one part of which alternately connects the PU signals and the other Pzi- signals. The switch controls the switch 4. Subject of the invention A multi-channel pneumatic computing device containing a pulse generator, a memory node, the output of which is connected to the output channel of the device, log-nodes by the number of input channels and the anti-log node, made in the form of a pulsating throttle, connected to the container and valve, characterized in that, in order to simplify the design, ystve multiinput set switch and a switch coupled to the switch inputs are connected to the outputs of the logarithm of nodes, and to pulysiruyuschemu The output choke unit antilogarifmiravani.
