Description

(54) MULTICHANNEL DEVICE FOR RECOVERY The invention relates to automation and can be used, for example, to automatically control the operation of a charging device for batteries. A device for restoring objects is known, which contains a switch, the inputs of which are connected to the outputs of channels whose request inputs through the OR element are connected to the inhibitory inputs of channels, and each channel contains a trigger, an element Zeffet, OR-NOT, NOT and an intermediate level sensor 111. Disadvantage of the device - the lack of priority of the inclusion of objects for restoration b depending on the importance of the functional purpose of the object. The closest to the technical cymHOGtH of the present invention is a multichannel device for restoring objects, containing a distributor and control channels for the number of objects to be restored, each control channel contains an element AND an element HaivwTb, two elements NOT, two elements OR NOT, an element OR block fixing and controlling the state of the object. Each

OBJECTS of the distributor output (the number of outputs of the distributor corresponds to the number of operating and then depleted and recoverable objects, i.e. the number of control channels) is connected to the corresponding first input of one of the And elements whose output is connected to the input of the installation of the Memory element. A single output of the Memory element is connected to the inputs of the first and second elements of the first and second elements that are interconnected through the first and second elements OR NOT connected to the restoration and disconnection inputs of the fixing unit and state of the object, the restoration request and the object are restored connected respectively to the second input of the And element and to the input of the setting of the memory element b; the output of the element OR of this object, the inputs of which are connected to the outputs of the first elements OR NOT other objects, is connected to the input of the first element OR NOT this object. Elements in the control channels for each object 2 are similarly connected. 37 -. -h However, in a known device, there are situations when an object that performs less important and demanding functions than others is attached to several objects that are waiting to be restored. This can lead to disastrous consequences, or at least to a serious accident of the whole complex. Thus, the lack of priority for the inclusion of objects in the restoration reduces the probability of trouble-free operation of the complex when performing the most important functional tasks. In addition, the known device contains many elements, which reduces its reliabilityN "3CTb. The aim of the invention is to increase the reliability of the device, in particular, by ordering the sequence of setting objects for restoration according to the tasks performed by them, and simplifying the device. The goal is achieved by the fact that in a multi-channel device for restoring objects, there is an element in each channel A memory, two elements OR-NOT, elements OR, and a block for fixing and controlling the state of the object, and the output of the element OR each channel is connected to the input of the first element OR-NOT this channel, the output of which is connected It is provided with one of the inputs of the OR elements of the other channels, with the input of the restoration of the latching unit and state control of the volume and with the input of the second element OR of the given channel, the output of the second element OR is NOT connected to the input of the shutdown to wait for the latching unit and state control the volume whose output the object is restored to is connected to the zero input of the element Memory the output request to restore the block of fixation and to control the state of the object of each channel is connected to the single input of the element Memory the zero output of which is connected to By the two inputs of the OR-NOT elements of this channel, the output of the second element OR-NOT of each channel is connected to the inputs of the elements OR of the subsequent channels. The drawing shows a block diagram of a multi-channel device for restoring objects. A device for restoring objects in each control channel contains a memory element, executed in the form of a trigger, the first element 2 OR-NOT, the second element 3 OR-NOT, the fixing unit 4 AND controlling the state of the object, the element 5 OR, the recovery request 6 outputs and restored 7 blocks 4 soyuzneng respectively with inputs installation 1 8 and installation O 9 of element 1 Memory, 1ulev (1st output of element I of I memory is connected to the first inputs 11 of the first and second element 2 and 3 OR - NOT, the output of the first element 2 OR-FfE is connected to the input 12 of the recovery block 4 f Curing and controlling the state of the object, with the second input 13 of the second element 3 OR-NOT and with the inputs of elements 5 OR of other control channels, the output of the second element 3 OR-NOT of each channel is connected to the input of the waiting for 14 block 4 of the same channel and with the inputs of elements 5 OR of all subsequent channels, the output of the element 5 OR of each channel is connected to the second input 13 of the first element 2 OR-Fffi .-) The device works as follows. In the initial position of element 1, the memory in all control channels is in the zero state, therefore, from zero outputs 10 elements. Memory to the first inputs AND elements 2 and 3 OR NONE of each channel is alarmed by high level signals corresponding to logic level 1. When This is where both elements 2 and 3 OR are NOT blocked, and signals are output on their outputs. with a logical level of O, so the signals to the inputs 12 and 14, the restoration of the shutdown on waiting for block 4 is not received. When the i-ro object is exhausted (when the i-th battery is discharged to the specified allowable voltage), the request to restore signal from output 6 of the corresponding fixing and control unit 4 to input 8 is set to 1 setting 1 of the i-th memory control channel. At the same time, at the zero output 10 of element 1, the memory has a low potential so that the first inputs of the 11 elements OR NOT do not receive signals with a logic O level. If at the considered moment of time there is no inhibitory signal at the output of element 5 OR of the i-ro control channel then the first element 2 OR-NOT does not work and generates a restore signal at the input 12 of the block 4 for fixing and controlling the state of the second object. Otherwise, the second element 3 OR-NOT is triggered, will form a sleep-out signal for input 14 of block 4. If, in the process of restoring the i-ro object, it becomes necessary to restore the object with a number greater than 1, then the latter goes into the shutdown mode for waiting , since the signal recovery from the output of the first element 2 OR-NOT of the i-channel of the channel is fed to the input of all elements 5 OR of other channels, forming prohibitive signals at the outputs of these elements. If in the process of restoring the i-ro object, a signal is generated. A request for an interrupt in the object with the number

smaller, for example, with the i-1 number, then in the signal generation mode, the interrupt request of the (i-1) -th object at the output of element 5 of the OR (i-1) -th channel has a inhibitory signal generated by the i-oro recovery signal channel, so at the output of the second element 3 OR-NOT (i-1) -th channel, a turn-off signal is generated. This signal, arriving at the input of element 5 OR the i-ro channel, generates a inhibit signal for the i-ro channel, as a result of which the restoration of the i-ro object ceases and it goes into sleep mode to wait. In this case, the recovery signal from output 2 OR-NOT of the i-channel of the channel ceases to flow to element 5 OR of the again failing object, therefore at its output 5 OR there is a enabling signal, and (i-l) -bm the object goes into recovery mode. The restoration of the i-ro of the object continues only after the completion of the restoration of the object with a lower sequence number.

In general, the i-th object can go into recovery mode only when all previous objects by number are restored,

The present invention allows to increase the vitality and efficiency of functionalization of equipment complexes containing a number of recoverable objects, due to the primary restoration of those objects that are designed to perform the most important tasks, because, in order to increase reliability, the most critical objects will be redundant, the proposed technical solution will allow

reduce the multiplicity of the reservation or completely eliminate it.
