The drawing shows the structural scheme of the proposed device. The device consists of a time sensor 1, a block 2 of the command code entry (BKKK), a software block 3, a block 4 of the starting command selection block 4 (BVNK) and the actuators 5. BZKK 2 consists of an input block ccafaf of command b connected to the first inputs of the ring shift registers 7 whose number is equal to the number of characters in the code | Somand. Program unit 3 contains a program input unit 8, connected to the first inputs of the annular shift registers 9, the number in which is equal to the number of executive mechanisms 5 of the same unit. The second inputs of registers 7 and 9 are connected to time sensor 1. Shift registers 7 and 9 consist of static triggers, the number of which is one more than the number of elementary commands into which the entire program is divided. The program input unit 8 comprises a pulse shaping unit in co. correspondence with the recording of the program (manually or automatically when read from the program carrier). Block 6 input of the initial commands consists of a diagram of the form of ani pulses in accordance with the individual command codes. Blocks 4 of the choice of the initial command line, which is equal to the number of machines, contain successively connected coincidence circuits, consisting of logical elements, the equivalence of 10 symbols in number. the code of the command and the logic element I 11, the statistical trigger 12 and the prohibition scheme consisting of the logic elements I 13 according to the use of the executing mechanisms of one machine. The inputs of the logic elements 10 are connected to the outputs of the registers 7, and the codes of the registers 9 are connected to the inputs of the logical elements And 13, which are connected to the actuators 5.. The device works as follows. Before starting the work, the program is entered into the shift registers 9 of program block 3. The pulses are fed from the program input block 8. Moreover, each register 9 has a program of operation of one executive mechanism 5. In the process of entering the program at the input (setting 1 to the extreme right triggers ) pd1Moyo6vayelno served with the eapisn) program. After filing the next signal 1, the write shifts to the left by one bit. Thus, after entering all programs consisting of elementary commands, 6 are set to 1 or O n triggers of registers 9, starting from the right. In BKKK 2 is introduced sequence krl. Commands with the help of block 6 of entering the code of commands in the same way as ect is done in software block 3. When the device is operating, time sensor 1 at intervals equal to the duration of the elementary operation, which the total cycle time is divided, supplies simultaneously the shift pulses to registers 7 and 9 After the initiation of one trigger pulse, program B1 of program block 3 (as well as a sequence of instruction codes in BKKK 2) is cyclically moved in registers 9. to one elementary command. In this case, the entire program and the sequence of codes are fixed by n triggers of each register 7 and 9, counted on the right. The last (n + 1) -trigger is only for temporary storage of information during its shift. After filing n shift pulses from time sensor 1, the program (and the sequence of codes) will take up the initial position in registers 7 and 9 and will periodically return to this position in the future. When you move the program, the triggers that are in state 1 include, and those that are consistent: O, -. disable the executive mechanisms 5, which ensures their operation in the sequence specified by the program. Using switching devices (in the drawing, plug connectors are shown as the last ones), the actuators 5 of the machine are connected through the prohibiting circuit BVNA to the output of any (by operator’s choice) discharge registers 9 of program block 3, Actuators 5 different machines can be connected to the outputs the same bit or to the outputs of different bits. In the first case, switching on the actuators of 5 different machines will occur simultaneously (synchronous program execution), and in the second, with a different time shift, measured by a certain number of elementary commands (program execution with a shift and phase). BKKK 2 together with BVNK 4 include the designation mechanisms 5 of each machine in operation only from the moment when the command taken for yachapnui appears in the discharge of the shift registers 9 selected for controlling the machine. For example, this may be the first command of the entire program. In addition, it is possible to pre-connect any (stopped for one reason or another) machine during the operation of program block 3 to any of its bits with the subsequent automatic activation of the actuators 5 at the moment when the initial command appears in the discharge (in as the latter, the command of the operation during which the machine was turned on may be received). It provides autonomous switching on and off of any machine without disturbing the rest. The serial number (code) of the initial command is input. Setting the initial command code in the form of single or zero signals, corresponding to the binary notation. If the command code in BSFCK 2 registers coincides with the set code at the outputs of the equivalence elements 10 of the comparison circuit, single signals occur, which, in turn, generates single signals at the output of the And 11 element. The latter translates trigger 12 into state 1, which is saved further until the machine stops, followed by a signal reset to the trigger input. Since the installation of the trigger 12 in the state-; G is supplied to the inputs of the AND 13 elements connected to it, single signals are supplied, which ensures that 1x signals from program block 3 controlling the actuators 5 pass through these elements. The main advantage of the invention is to increase the economy of washing masses: 11ShN by increasing the accuracy performing technological operations in time, ensuring autonomous switching off and on any. machines to work, starting with any operation of the program without interrupting the work of the remaining Machines and providing increased reliability due to the lack of contact elements. Claim 1. A device for controlling a group of washing machines, comprising a time sensor, a program block and an actuator, differs in that, in order to increase reliability, accuracy and efficiency of control, it has a command code recording unit consisting of ring shift the registers by the number of characters in the command code and the command code input block connected to it, and the initial command selection blocks for the number of machines, the outputs of the command code writing block and the program block are connected to the block inputs Selecting Primary commands come out Kotopbix ispolnitelnkmehanizmov connected to the inputs and registers koltsevyesdvigayuschie instruction code write unit connected to the programming unit via the time clock. 2. The device according to claim 1, characterized in that the program block consists of circular shift registers according to the number of actuators of one machine connected to the program input block.
