and the output of the first integrator is the second output of the evaluator.

The invention relates to training devices in the field of loading and unloading operations for the purposes of vocational training, as well as testing and upgrading the qualifications of ship boom lifting machine operators (PMG) using the telephone method under the conditions of an educational class.

Simulators are known that contain operator pulp, blocks for modeling real processes, logical processing and presentation of educational information l | and z.

However, these simulators do not allow operators to be trained in using two lifting mechanisms at the same time.

Closest to the invention is a simulator containing a sequentially connected unit, inputting a response action and a modeling unit for real processes, each of which includes two identical channels A and B for a winch, as well as a unit for calculating cargo coordinates horizontally, an image forming unit and electronic beam indicator h.

A disadvantage of the known device is the impossibility of its use for training ship boom PMG operators to overload cargoes by the telephone method, when one operator must control two winches at the same time.

The purpose of the invention is to expand the didactic capabilities of the device by adapting it to train shipborne rifle operators.

The goal is achieved by the fact that two calculator of tension of ropes and an additional modeling block are introduced into the simulator containing the sequentially connected operator response input block and the block of simulation of real processes, as well as sequentially connected block of cargo movement modeling, image forming block and electron-beam indicator moved the research institute of cargo, the first output of which is connected to the second input of the imaging unit, the second output of the first inputs of the first and second calculators on m voltage cables, and

5 real processes, respectively.

The rope tension calculator contains a series-connected first adder, a first integrator, a second adder, and a first multiply node, the output of which is connected to the first input of the first adder, the second multiplier node, the third adder, the second integrator, the first functional

"J transducer and the third multiplication node and the series-connected second functional transducer and the fourth multiplication node, the input of the second pulse driver

0 is connected to the output of the second integrator, and the output is connected to the first input of the second multiplication node, the second input, which is connected to the output of the second I adder, the second inputs of the third and

5 of the fourth multiplication nodes are connected to the output of the first integrator, the second input of the first multiplication node is connected to the output of the first functional converter, the second inputs of the first, second and third adders are the first, third and second multiplicator inputs, and the outputs of the third and fourth multiplication nodes are the first output the calculator, and the output of the first integrator - the second output of the calculator. FIG. 1 shows a block diagram of the proposed simulator / in FIG. 2 is an example of a specific implementation of rope tension calculators. The simulator contains a block 1 input response, and block 2 simulation of real processes, each of which includes two identical channels. Block 1 is the typical command devices 3 and 4, used to control lifting winches on ships. Block 2 contains two solving devices 5 and 6 to solve the following differential equation system of scientific research institutes: drive and mechanism of the winch, reduced to the circumference of the drum; F, is the tension force of the rope; t is the length of the rope. The outputs of block 2 are connected to the inputs of the calculators 7 and 8 of tension of the ropes, which through blocks 9 and 10 tical and horizontal) are connected to the image formation unit 11 connected to the electron-beam indicator 12. The calculators 7 and 8 are designed to calculate the tension of the winch cable A and B, the basic F and Fg, and the sine and cosine components. The calculator 7 is the decisive device of the following system of equations :.) p (3-, 1l 1. U,, where Xg and YQ are horizontal and vertical coordinates of the suspension point of the rope BJ X and Y are the coordinates of the load / stretch of the rope; the angle of deviation of the rope B from the vertical j c is a constant coefficient. FIG. 2 depicts an ISIS adder, integrators 16 and 17, multiplication nodes 18-21, and functional converters 22 and 23. Block 9 is a solvable differential equation with C ASOSE + B f Block 10 is the solver of the equation equation R. (10) From the outputs of blocks 9 and 10, analogs of the coordinates of the load Y and Xg are fed to the input of block 11, which is designed to receive signals with which an image of two lines connecting the point indicating the load is formed on the electron-beam indicator 12 (ELI) , with rope suspension points. Unit 11 contains four identical channels, each of which consists of an operational amplifier, transis; Toric keys, capacitors, resistapopo and a transformer (not shown). On the screen of the indicator 12 you can see the image of the cargo in the form of a point, two ropes, a load connected to the suspension points of the ropes: the image of the vessel (section) and the pier section, which are marked on the indicator screen 12 with paint. Simulator operator lifting machines works as follows. In the initial position, the cargo is at the bottom of the vessel. Training, controlling the levers of the command devices 3 and 4, one or two at once, lifts the load and moves it to the pier. Moving the control lever 3

or 4 leads to the closing and opening of contacts of the relevant block 2, which leads to the appearance of signals at the erq output - analogous to the length of the rope A (fj). A change in g causes a change in the tension of the cable Rd and its components Rd sin oi Rdsobob, which leads to a change in the coordinates of the load Xj and Yj ,. Further, through feedback circuits, the state of calculators 7 and 8, etc. is changed. The processes occurring in the simulator blocks are similar (isomorphic) to the processes that would occur in a real GPM, a-. since they are subject to the same differential equations as the real GPM.

The input of block 11 receives analogs of the coordinates of the cargo X and YC “. The coordinates of the pivot points Xd, Ud, HcI Yg are specified in block by 11 analog signals. On each of the chtefeh Kana-. block 11 receives analogs of one coordinate of two points. For example, analogs of Xd and Xj come in to the input of the amplifier of the first channel. A constant voltage is applied to the input of the integrator amplifier. When the voltage at the integrator output becomes greater than -UX (a positive voltage appears at the output of the amplifier of the first channel and opens a capacitor discharge circuit in the feedback circuit of the amplifier. As a result, a sawtooth voltage appears at the amplifier output, the amplitude of which is the difference C (-C (,, and the frequency is more than 50 Hz.

Next, the sawtooth voltage from the output of the amplifier is summed with the voltage Sh. This resulting voltage is applied to the input of the transfer switch, which is controlled from the secondary winding of the transformer located in block 11.

The transformer has four secondary windings connected in pairs in opposite directions in such a way that only two keys are open at a time for each half period. Two signals simultaneously arrive at the deviation to the indicator system 12: one to form a line along the X coordinate, the other along the Y coordinate. The first half-period forms an image of the AC line, the second half-period forms the BC line.

0 Repeatedly the cycle of cargo transfer from ship to shore and back, the learner acquires the skills to control the lifting winches when the cargo is loaded using the method 5 telephone.

i. .

The application of the proposed simulator for training in the management of hoisting machines is expediently varied for the training of sailors / operators of deck handling machines. At the same time, the labor productivity of the newly trained by the operator is repeated, the number of breakdowns of the mechanisms during training is reduced, the probability of accidents and accidents during training and due to poor operator training is eliminated.
