In the process of working d / vngatel, and the actuator, in order to maintain the normal mode of operation, the hovercraft requires it to be rocked and samopoev bleed or to maintain the pressure in it when the pressure is exceeded due to heating. Pumping and bleeding is performed by the operator on the control and signaling unit with a control key, depending on the state of the MSS. In the case of loyalty signaling or as a result of erroneous actions of the operator MOP. Can get out of the line. A continuous process of monitoring and controlling the maintenance of the continuous operation of the MMP t | rebuy Tto a different operator load.

the input is connected to the output of the speed sensor, and the output is connected to the corresponding input of the analyzer unit.

The drawing is a diagram of the proposed device.

The device contains: a bliss ul-ravlenn and alarms 1, sensors to the minimum pressure ("emptied) 2; nominal pressure sensor ("full") 3; maximum pressure sensor ("pumped over") 4; Klalan filling: FPM 5, Klalan emptying PFM 6, control key 7, filling prohibition sensor 8, speed sensor 9, indicators of pressure sensors (signal lamps) 10-12; control unit for emptying 13 CPM; block analyzer 14; filling control unit 15; interrupt unit 16; alarms "filling failure 17; alarm “emergency alarm 18; account block 19; the leakage detector “PBM grass 20; signaling device "PMM warms 21; reset alarm 22; the element “PE 23; an element of us is 24 triggers of the block of account 25, 26; "And 27, elemept" NOT 28; the element “H and the element“ NOT 30; the element “OR 31; element “AND 32; the element "NOT 33; power amplifier 34; delay element 35; element ia / mt 36; button 37 for the signal "emergency filling or emptying"; elements “AND 38-39, elements“ NOT 40, element “IL.I 41, element“ And 42, element “NOT 43, power amplifier 44; delay element 45; memory element 46; elements “And 47, 48; isolation diode 49; a and b - control key position 7.

The preconfigured device for controlling the PWM works as follows.

In the initial state, the PLC is emptied, the sensor 2 of the emptied BFM is closed, on the Uiravle unit. DIABY, and the alarm 21 only the lamp is lit, 10 p.m. The PLC is empty, the control key 7 is in the neutral position, the valves 5, 6 are filled and the PLC is empty . From the sensor 2 of the empty PLC, signals are received: at the input of the analyzer unit 14 to the element 23 and to the element 24 and v input of the counting unit 19 to the elements 25 and 26.

To execute the FPA, the operator on the control unit and the alarm 1 sets the control key 7 to the position b; the signal for filling the PWM is fed to the input of the control unit for filling the PWM 15 to the element “AND 27”, the same signal can also occur when sending the command for filling the PWP from external devices. If the input to the control unit of the FPA filling to the element 27, in addition to the above-mentioned signal, is received by the signals from the FPM filling prohibition sensor 8, which is not prohibited from filling the PLC from external systems, and from the speed sensor 9 through the element "NO 28, which is the shaft speed the engine does not exceed D01 allowed for filling W | PM, then from element 27 to 4

step signal to the input of the analyzer} 4 to element 29.

Elementite 29, in addition to the signal from element 27, receives a signal from element 30; the same signal from the output of element 30 is delivered to the input of element 38, from the filling sensor of SHPM 5. From element 29, the signal comes to the element OR 31 and then through it from the output of the analyzer unit 14 to the input of the block

interrupt 16 to the element "AND 32. Since the other | Input element 32 receives a signal from element 33, the signal from the output of element 32 goes to element 34, from the output of which the signal goes to the input of element 35, and simultaneously from the output of the interrupt unit 16 - to the valve of the optional winder 5. The valve opens, the winder starts to be filled with compressed air. As the CMM is filled, the sensor 2 of the emptied SLM changes its

the position and the signals received from it at the input to the control and signaling unit / to the lamp 10, to the input of the analyzer unit to elements 23 and 24 and to the input of the counting unit to elements 25 and 26 disappear.

When the FPM is filled, the filling sensor 3 changes its state and outputs signals to the input of the control and signaling unit to the light bulb "filled 11, to the input of the analyzer unit 14 to the element 24, in which

the alarm is activated; from the output of element 24, the signal enters the inputs of elements 38 and 39 and to element 30. When a signal arrives at the input of element 30, the signal at its output disappears, respectively, one of the signals at input of element 29 disappears, and, therefore, the signals at the outputs of elements disappear 29 and 31 and at the corresponding output of the analyzer block 14. As a result, the input signal at the input to the interrupt block 16 to one of the inputs of elements 32 disappears, and therefore, the signal from the output of this element disappears, which causes the following signals to disappear: from the input and output Yes element 34, from the input of element 35, from the output of interrupter unit 76 to the valve of filling of the MRM 5. The filling valve of the MRM is closed, the filling of the MRM with compressed air P1 stops. The hovercraft is full and ready to go. Since during the operation of the hoist gear motor

As a rule, the speed is higher than acceptable for the eMAN system, then the signal from the speed sensor 5 and the input signal to the filling control unit 18 to element 23 causes the signal at the output of element 28 to disappear. Consequently, one of the signals at the input of element 27 disappears and the following signals disappear: at the output of element 27, i.e. at the output of the filling point control unit

block analyzer 14 and at the other input element 29.

If the direction of the MSS continues beyond a specified period of time monitored by element 35, i.e. the sensor filling the MLC 3 during this time has not changed its state n. (If there are signals at the discharge of element 34, and, therefore, at the input element 35 of the FPM filling clan 5), then after the end of the call is sustained, the signal from the output of element 55 is sent to the input of element 36, in which this signal is marked. From the output of the element 36, the signal arrives “and the input of the element 33; The signal from the output of this element disappears, respectively, the signals from the outputs of elements 32 and 34, and from the output of the Pryrgva)) module 16 disappear at the bottom of the PLC, and at the same time the signal from the output of element 36. the “emergency; full, and 17.” light bulb. Upon receiving this signal, the operator must set control key 7 on the control unit to the neutralization / neutral position and take measures to eliminate the malfunction. The signal "emergency": the situation can be cleared by the operator by pressing the button 57 on the control unit signaling signal 1.

If during operation the pressure in the PLC starts to drop due to air leakage, then the sensor of the filled PLC 5 will change its position (open the circuit) on the control block and the sigalization, the lamp will be filled 11 (while on the control and signaling unit one lamp is off). At the same time, the signal from the sensor of the nanolysis CPM disappears at the input of the analyzer unit 14 (at the input of elements 24 and 30), but in the element 24 the filled state of the CPM n s is fixed, and the output at its output remains. The signal at the output of element 30 appears again and is fed to the inputs of elements 29 and. Since there is no signal at the other input of element 29, there will be no signal at its output.

If there is no command for stopping the winder (from the unraught key 7 or from external devices), then the analyzer unit 14 input to the third input of the element 58 is constantly received from the output of the control unit of the drm machine (from the output of the element 40). Therefore, when an input element 58 enters the input of the element 30 (the output signal of the element 24 enters the input of the element 58 earlier) at the output of the element 58 through the V-SIRNAL, which enters the input of the element 31 and then the output analyzer 14 is input to interrupt unit 16 to elements 52, S4 v. from the output of the interrupt block 16 to the VLBM filling 5.

The program of operation of the circuits of the interruptions block 1 €, the valve for filling the MW 5 and the sensor filled by the MW are similar to the previously described case for filling the MW (taking into account the emergency situation).

After each pumping up, when the sensor is filled with filled MLC 5, the device returns to its original state.

At the same time, the signal from the output of element 58 is fed through the output of the analyzer block J4 to the input of the counting block 19 to the elements 25,

which za1: omi; Each case of ovoshkatl Bleed CHPM during operation. After exceeding the number of swapping of a predetermined number embedded in the counting chain, from the output of elements 25, i.e., from the output of the counting unit 19 to the input of the control unit and alarm system / the signal to the "MFR etch.

If during operation the pressure in the PWM

starts, i.e., the pressure in the PLC is increased by heating the compressed air in it, the sensor of the pumped PLC 4 changes its position (closes the contact), B: as a result, the control panel 12 "lights up on the control unit and the alarm 1 And the input of the block-analyzer 14 to the element 59 receives a signal. Since at the other input of element 39 there is a signal from element 24, the signal from the output of element 39,

i.e., from the output of the block-analyzer 14, the input of the counting unit 19 enters the elements 26 n to the element 41 and then from its output through the output of the black analyzer to the input of the interrupt unit 16 to the element 42. Since

element 42 enters the signal from element 43, then the signal from the output of element 42 enters element 44, the output of which is fed to the input of element 45 and simultaneously from the output of interrupt block 16 - to

valve for emptying the hoist tube 6. The valve opens, the compressed air from the hopper tube starts to bleed. At the same time, the signal that was accessed from the output of element 59 to the input of elements 26, in which each case of BGM etching during operation is memorized, after exceeding the number of inclusions of etching a predetermined number embedded in the counting chain, from the output of element 26, i.e. . from the output of the account block

To the input of the control and signaling unit 1, the signal to the light bulb 2 is received. The warhead grill heats up.

"Ne; rekakcheno on the control unit and alarm 1 goes out, disappeared, there is no signal at the entrance to the analyzer unit 14 to the element 59, and, therefore, the signals from the inputs and outputs of the elements 41, 42 n 44 and finally from the emptying valve MOP 6, which after K | rumbles, the release of compressed air from the MMP stops.

To empty the FPGA, the operator on the control unit and the alarm / sets the control key 7 to position a; at the same time, the signal for emptying the PLC is fed to the input of the control unit for emptying the PLC 13 to the element 47; the same signal can take place when the command is given

emptying the CPM from external devices. If the 1 INPUT block of the control unit for emptying the PWB 13 to the element 47, in addition to the above signal, receives a signal from the speed sensor 9 that the engine shaft does not exceed 1T permissible for emptying the PWB,

then from element 47 lostula signals to the element 40 (the signal at the output of the latter disappears) and then to the output of the control block for emptying the MW 13 and to the input of the block analyzer 14 and to the element 48. As with an empty FCM from the element 23 to the other internal element 48 also receives a signal (the sensor of emptying of the MLC 2 is open), then at the output of element 48 a signal appears that goes to the input of element 41 and then to the output of the block analyzer 14, to the input of the gate 16 via elements 42 and 44 -in the valve of emptying of the hovercraft 6. The valve opens, the hovercraft starts up Rozhnev employed.

When the CPM is emptied on the control unit and sirnalization / the lamp 11 is extinguished and the CPM is emptied, when the sensor of the emptied 2 closes its contacts, on the control unit and the alarm / the 10 "lamp lights up. At the same time, the signal from the sensor of emptied PLC 2 enters the inputs of the analyzer unit 14 to element 23 (IB, resulting in the signal at the output of element 23 disappears and, obviously, the signals at the outputs of elements 48, 41, 42 and 44 and at the inputs of the element 45 and the CPM 6 outbreak valve, which returns to its original state by closing the compressed air outlet port of the CSM), and to element 24 (as a result, the signal corresponding to TOMiy that the MRF was previously parfolip in this element is reset). The signal from the sensor 2 also enters the inputs of the counting unit 19 to the elements 25 and 26, as a result of which they accumulate in them, they are given about boating and they do not turn off the DRMs; The same can be done by aperture by pressing the reset button on the control unit 22 on the control unit, and the alarm. The device comes back to its initial state, the PLC is emptied. If the emptying of the PLC was over a specified period of time (controlled by element 45), i.e., the sensor of the empty PLC during this time did not change its state Ny (with available signals on you-stroke of element 44 and, therefore, at the input of element 45 and the valve for emptying the FPM 6), after the end of the time delay from the output of the element 45, a signal arrives at the input of the element 46 in which this signal is memorized. From the output of element 46, the signal enters the input of element 43, the signal from the output of this element disappears, then the signals from the outputs of elements 42 and 44 n, respectively, from the output of interrupt unit 16 to the emptying valve of CMM 6 disappear, the valve closes, the emptying of IRB stops, and simultaneously the signal from the output of the element 46 to the input of the control and signaling / to the light bulb 18 "accident is empty 1i. The operator, having received this signal, should set the control key 7 to the neutral position (or eliminate the signal for emptying MTS from external devices) and take measures to eliminate the malfunction. The "emergency emptying" signal can be cleared by the operator by pressing the button 37 on the control and alarm unit /.
