23 matches, counter 24, register 25, element 26 and element OR 27, information inputs 28 and input 29 Device reset, input 30 Start, address inputs 31 and clock input 32 of block 13 for emergency detection, outputs 33 and 34 of block 13.

The device works as follows.

In the initial position, the triggers are in the reset state. In the first block 1 of the memory, the addresses of the monitored monitored parameters are stored in the order of their interrogation, in the second block 2 of the memory - the addresses of the object's emergency parameters, i.e. parameters that can cause an emergency both individually and in combination. The third block of 3 memory stores the addresses of the parameters that can collectively cause an emergency. These addresses are divided into sets of parameters, i.e. the parameters of each set are stored in the neighboring memory cells and, during the operation of this block, are called cyclically within the set. Counter 11 is in an arbitrary state, which does not affect the operation of the device. The register of 25 addresses and counter 24 are reset. In addition to the addresses of the corresponding parameters, the first and the third memory blocks store the values of the monitored parameters corresponding to threshold levels that go beyond the limits for the first emergency memory block 1, and for the third memory block 3 - a possible emergency situation on set of parameters. Naturally, the values of the control levels of parameters recorded in memory block 3 are less than the corresponding levels recorded in the first memory block 1, since the emergency value of a single parameter is always greater than its value, causing an emergency situation in conjunction with other parameters .

According to the signals from the 17 clock pulse generator, the first memory block 1 issues sequentially (in accordance with the polling order) addresses of monitored parameters to the second and third memory blocks, as well as to the local switch 8 and Gmyuk 2 regist0

walkie-talkie information. At the same time, the first memory block 1 outputs the control (threshold) value of the corresponding parameter to the first block 9 of the comparison. The other input of the first comparison unit 9 receives the current value of the monitored parameter from the input switch 8.

In the absence of an emergency, the following signals are sent to the information recording unit 12: from block 13, a signal is received at input 34, enabling address sampling by signals from memory block 1; from the input switch 8 the current value of the parameter; from the element OR 6 signal of the absence of the control of the parameter recording: from the element AND 4 - the signal of the absence of a ban on further registration.

When an emergency value of an individual parameter is received, the device is operated in accordance with the timing diagrams in FIG.

In case of detection by the comparison unit 9 of the fact of the output of this parameter outside the permitted zone, block 9 generates a prohibition signal for the second comparative block 10 to operate (this block should work because its control value is less than the control value of the parameter issued by the first memory block 1 ti). The signal from block 9 also enters the element OR 6 and, by allowing signals to it from the first trigger 14 and memory block 2, through the element 5 enters the Reset input of the counter 11 and sets the first trigger 14 to the one state. OR 6, the signal also enters the information recording unit 12, by this signal in block 12 the emergency parameter is recorded at the address provided by memory 1, simultaneously with the registration of emergency time, unit 16. Thereafter, the trigger 14 is set to one. zi further resets the counter 11. Subsequently, the parameters that go beyond the allowed zone are recorded until the counter 11 is filled, which, when filled, issues an inhibit signal to the information recording unit through the AND 4 element, after which further event registration stops prior to the communication session with the central receiving point or until the control information is removed in any other way. This order of operation prevents the loss of emergency information. The number of recorded events in the absence of an emergency is limited by the memory capacity of unit 12, which can operate either in linear mode (before filling). or in a cyclic mode (upon filling in the block, the new information is recorded in the place of the oldest). When an emergency situation occurs, after the registration is completed, in block 12, the recorded information N-n-1 of events before the emergency and n events after the emergency is where Nun is, respectively, the capacity of block 12 and counter 11.

In case of detection by the comparison unit 10 of the fact that a certain parameter has exceeded the established limit, which in combination with others can create an emergency situation, the device works as follows.

In this case, the second comparison block 10 is triggered, but the first comparison block 9 does not work. A signal from the output of the second comparison unit 10 (in accordance with the timing diagrams in FIG. 4) starts the operation of the block 13, switches the input switch 8 to work by the addresses specified not by the first but by the third memory block 3, sets it to one the second trigger 15. On the output signal of the second trigger 15, the operation of the first memory block 1 is prohibited and the third memory block 3 is allowed to work, which double enumerates the associated set of parameters with the parameter exceeding the corresponding value of the cumulative allowed zone During the first iteration by the memory block 3 of all parameters of the aggregate, the block 13 detects the presence of an emergency situation.

The operation algorithm of block 13 is co-operative. Block 13 issues a decision on the presence of an emergency situation if all the parameters of the aggregate are outside the allowed zone, determined by the control levels recorded in memory block 3 and issued by it to the second block. The signals shown in the timing diagram of FIG. A correspond to a combination of three parameters.

When a second comparison unit 10 is triggered by a certain parameter that is not emergency, but together with the other two parameters, to cause an emergency situation (in FIG. 4, this corresponds to times tt and t "), the address of this parameter is written to register of 25 addresses. In addition, a trigger 21 is set, thereby prohibiting through the AND 18 element

5 change the contents of the register of 25 addresses. The third memory block 3 enumerates all the parameters of the given set. If one of these parameters (in Figure 4 - the second parameter) does not go beyond the permitted zone, the trigger 21 is reset and through the elements HE 26 and AND 19 and the signal from the generator 17 clock pulses outputs a signal to the element

5 OR 27 and then to the element OR 7 and to the reset of the second trigger 15. switching the device to its original state (i.e., operation from the first memory block 1). This switch means that one of the parameters does not correspond to the zone of values that can cause an emergency situation, and the emergency situation in this case is not fixed.

If, in the process of analyzing the totality of parameters, all of them went beyond the limits of the allowed zone (which is fixed by trigger 21, which in this case is never reset for

Q), at the end of the first iteration, the third memory block 3 again returns to the first parameter, which caused a switch to the corresponding detection mode. In this case, the address of this parameter triggers the block 23 of address matching. The signal from the address matching block is added to the contents of counter 24. This

0 counter counts up to two, fixing two iterations of the set of parameters. The signal from block 23, in addition, through the element 20 on the permissive signal from the trigger 21 sets

5 trigger 22, which, at output 34, performs the following actions (in FIG. 4, time point tj): the information recording unit 12 switches not registering parameters by addresses,

specified by the third memory block 3; through the elements OR 6 and AND 5 resets the counter 11 and sets the first trigger 14, which signals the presence of an emergency and prepares the block 12 to limit the registration after the emergency in order to avoid the loss of the emergency information. After the indicated actions on clock pulses, the second search of the set of parameters begins. If the first search was intended to analyze the presence of an emergency, then during the second search, the emergency (in aggregate) parameter values are recorded in the information recording unit 12. The signal from element 4 allows recording. The signals from block 3 specify the addresses of the aggregate parameters. The signal on output 34 of block 13 determines the fact that the addresses are taken from block 3.

After the end of the second search, block 23 is again triggered, counter 24 outputs a signal resetting the address register 25 and trigger 22, and also resetting the second trigger 15 via the element OR 27, which returns the device to the sequential polling mode by the addresses specified by the first memory block 1 (time t. in figure 4).

Thus, the device allows recording not only emergency situations that occur when individual parameters leave the allowed zones (reference values), but also emergency situations that occur when the set of parameters of some specified reference values is exceeded, which also creates an emergency situation.
