A device for controlling the sequence of polling information objects is known, which contains a central unit and several local data input consoles connected by a common CO bus. This device cyclically polls information objects as they are ready. During the transmission of information of one object, the interrogation of other objects is not performed.

The disadvantages of this device are their low speed and limited functionality, since it lacks nodes and connections that automatically automatically conduct a priority survey of priority objects, depending on their readiness and degree of significance.

A known adaptive switch for polling information objects containing a block of output cells of information objects, the outputs of which are connected to the first inputs of the key elements of the serial information output unit, the second inputs of which are connected to the corresponding outputs of the distributor, the outputs of the key elements of the serial information output unit are connected to the first inputs of the reading unit information and inputs of the control unit of the distributor, the output of which is connected to the input of the distributor, the outputs of the counting unit Information flows are connected to the output terminals of the switch [2].

This device does not allow providing a priority survey of priority information objects as they are ready and the degree of significance.

The aim of the invention is the expansion of functionality.

This is achieved due to the fact that a priority setting unit, a priority allocation unit, are introduced into the proposed device.

72184 information, OR element, information significance highlighting unit, priority information output unit, priority setting unit and output cells of information objects block outputs are connected to inputs of the phone 2 allocation unit, on the other hand, to one of the first inputs of the information reading unit 6, allowing thus polling the selected object. During data transmission, polling of other objects is not performed ⁵ . After the end of the survey, the signal to prohibit the start of dispenser 2 is removed and the survey of other objects begins. If there is a priority set by block 7, the priority signal for one of the buses of block 7 is fed to the first inputs of block 4 for priority information allocation, and signals from block 1 of output 15 cells 1 ^ - 1 _{p of} information objects are sent to the second inputs of this block. If these two signals coincide, the output signal from block 4 goes to the second inputs of the cells 8, -8 _p of the priority information output block 8, to the corresponding inputs of the information significance block 9 and the OR element 10. As a result of the operation of the OR element at the third inputs of the cells 5 _L , 5 ^.

It contains a block of output cells of information objects 1 with cells 1 ₄ , ig ... 1 _p , a distributor 2, a distributor control unit 3, a priority information allocation unit, 4, a sequential information output unit 5 with cells 5 ^, 5 ₂ ... 5 _P , information reading unit 6, priority setting unit 7, priority information output unit 8 with cells 8, -8 _p , information significance allocation unit 9, OR element 10.

The device operates as follows.

In the absence of priority, information objects are polled ^{40 in the} usual way - sequentially. Signals output from the unit cells 1 1y, 1 ^ 1 ... _n information objects to a first input key element 5 ^ -5 _P sequence block 5 ⁴⁵ Foot information output to the second input key element receives signals from the distributor 2.

At each step of the distributor 2, provided that a signal arrives from the output cell of the block 1 corresponding to the given step of the distributor, one of the key elements 5 ₄ -5 _{p of the} block 5 for serial output of information is triggered. The output signal from the selected element, on the one hand, goes to the distributor control unit 3, which stops the distributor. As soon as block 9 selects the degree of significance of priority objects, the output signal from block 9 passes through the bus with the highest degree of significance to the third input of one of the cells 8 ^ 8 ₂ ... 8 _P block 8 output priority information, on the other output buses of block 9 to the third inputs of the cells of block 8 will be banned. Thus, the survey of the selected cell with the highest degree of significance will be carried out first.

Subsequent interrogation of cells of block 8 will be carried out similarly, depending on the degree of importance of priority objects.

Introduction to the adaptive switch for polling information objects of the above blocks made it possible to provide a priority survey of priority objects 721 (tov, depending on their readiness and significance, and to expand the functionality of the device.
