Description

one

The invention relates to the field of automation and computer technology, in particular, to technical means of training and can be used for professional selection, vocational training, as well as for checking the qualifications of crane operators under training class conditions by assessing the quality of crane control skills.

A device for training a crane operator is known comprising a manual control unit connected to the inputs of a real process simulation unit whose outputs are connected to an adder and a signal converter connected to an educational information display unit that is connected to the outputs of an adder connected to a signal converter via a switching unit of information signals one.

In this device, the quality of crane control skills is evaluated by the instructor visually from the picture of the control process observed on the screen of the information display unit. The device does not allow obtaining quantitative indicators of the quality of control activity.

The lack of quantitative indicators of the quality of management activity excludes the possibility of establishing a reliable assessment of the quality of crane management skills and effective student self-control.

The purpose of the present invention is to increase the accuracy of the device, which increases the effectiveness of training by providing an active self-monitoring student.

This goal is achieved in that the device contains an operation counter, a start and end task control unit, a time counter, an overload signal storage unit, a process parameter determination unit, an extremal parameter determination unit, a threshold unit, an error value determination unit, a switching unit error signals and the evaluation definition unit connected to the educational information display unit and to the output of the error signal switching unit, the inputs of which are connected to the outputs of the threshold unit and the unit error limits connected by the inputs to the outputs of the operation and time counters, the overload signal storage unit, the technologi cal determination unit. paramst | X) c and the irsdel section 1n of the extremes of the parameters, which is connected to the inputs of the input signal converter and connected to one input of the technological parameters determination unit, the other inputs of which are connected to the outputs of the simulation block of real processes and the control unit of the beginning and end of the task execution which is connected to a real process modeling unit, a time counter and an overload signal storage unit connected to a real process modeling unit, the operation counter inputs are connected to a manual control unit, the outputs are connected to a training information display unit that is connected to an MCini time counter and a threshold block connected with a technological parameter determination unit and an overload signal storage unit.

The device for training the crane operator (see drawing) contains a manual control unit 1 connected to the inputs of the simulation module of real processes 2, the outputs of which are connected to the adder 3 and the signal converter 4 connected to the display unit of training information 5, which through the block com. the mutation of information signals 6 is connected to the outputs of the adder 3 connected to the signal converter 4, the evaluation definition unit 7 connected to the educational information display unit 5 and to the output of the signal switching unit 8, whose inputs connected to the outputs of the threshold unit 9 and the unit for determining the values of the external 10, connected by inputs to the outputs of the operation counter 11 and the time counter 12, the memory block of the overload signals 13, the detection unit |) of the technological parameters li and block determination are extremal (values 15 meters, which is connected to the inputs of the threshold unit 9 and the outputs of the signal converter 4, by ;; key to the input of the block defined by technical parameters 14, the fugie inputs of which are connected to the outputs of the block. in 2 and the start and end control unit of the task 16, which is connected to the real process modeling unit 2, time counter 12 and the overload signal storage unit 13 connected to the real process modeling unit 2, the inputs of the operation counter 11 are connected to the manual control unit 1 , outputs - to the educational information display unit 5, which is connected to the time counter 12 and the threshold unit 9 connected to the process parameter determination unit 14 and the overload signal storage unit 13.

The device for training the crane operator works as follows.

We train the 1.1Y to perform control octerations with the help of the command and control devices of the manual manual unit 1. With this, he observes-1 the result of his actions J on the screen of the educational information display unit 5. At the outputs of the mainstream simulation of real processes 2 and converter 4, the current values of the process parameters for load transfer are formed. At the time of rupture from rue; 1i at the output of block 16

0, a si-nal is formed, over which mx time counter 12 is started and the speed of the rope is remembered at the moment of cargo detachment from the ground by block 13. TaKi.i form, an overload of the hoist mechanism is detected. In the process of cargo valuation, block 15 allocates and remembers the maxima of the load from the point of suspension, and in block 1 the number of switchings of command post operators is calculated. Iljin lowering the load on the ground on Bbixo; ie blocks 16
