Description
Technical Field
The invention relates to the field of operation safety, in particular to an operation step drilling and guiding device and a logic control method.
Background
Currently, automated production is spread throughout various industries, but still a large number of manual operation work scenarios exist; there are generally three cases where automated production is not possible or desirable: firstly, automatic production is adopted, and input and output are not matched; secondly, the automatic production cannot be adopted; third, there is automation but in some cases manual operation. In the case of manual operation, the skill of the operator and the proficiency are extremely important, and particularly, some operations are very complex and the sequence of steps is also very important, so that once steps are omitted, the steps are wrong, equipment is damaged if the steps are wrong, and the life safety of people is endangered if the steps are serious.
One possible manual operating scenario is: when a high-voltage power user, especially a factory and mine power distribution room, electricians operate at high voltage, if misoperation occurs, the consequences are very serious, for example, when high-voltage power transmission is recovered after a certain transformer is overhauled, a temporary grounding wire is firstly detached (or a grounding disconnecting link is pulled open), then a handcart type circuit breaker is pushed to a working position, and then the circuit breaker is closed for power transmission, wherein three steps can not be reduced, one step can not be reversed, otherwise, accidents of burning out equipment, even electric arc burning and electric arc electric shock accidents can be caused; in a power distribution room, a complex operation task often needs dozens of steps, and different power supply modes have different operation tasks, so that an electrician is required to have high technical and psychological qualities.
Another possible application scenario for manual operation is: in the event of accidents, at start-up and shut-down of hydroelectric power plants and other accident management, the automation equipment is rendered unusable due to tripping of the operating power supply, it is further necessary for the operator to be calm, to perform start-up or shut-down operations by manual operation, and to perform other tasks, these operations are often very sequential, with one step being never few and one step being not reversed, or else with serious consequences, if the machine is started, the steps of releasing the brake air brake, closing a brake air pipe valve, withdrawing the servomotor for locking, inputting cooling water, opening a guide vane to be idle, increasing excitation, inputting a synchronous device, closing a breaker for grid connection and the like must be carried out in sequence, the accidents such as bearing bush burning loss and the like are likely to be caused due to improper operation, these also test the skill proficiency of the operator and the good psychological quality, which often depends on training at ordinary times.
However, these manual operations have a common feature, which often does not allow an operator to train on the actual operating equipment, and objectively requires a training function device to enhance daily training.

in the process of professional ability training and appraisal, equipment capable of realizing the training of the operational technical key points is often needed, actual equipment is sometimes impossible and sometimes cost is not reasonable, and a practicing device with the actual operational steps for training the technical key points is quite necessary, such as:
at present, the national emergency administration prescribes that all personnel engaged in high-voltage electrician operation must obtain special high-voltage electrician operation permit through the training, do not have corresponding high-voltage electrician training set in the patent retrieval at present, each training agency generally adopts industrial high-voltage board to carry out the training of national emergency administration prescribes subject among the prior art, but the screen cabinet of these industrial uses, only adapt to infrequent operation, to the student's operation of high frequency, brought the equipment fault rate height, simultaneously the price is expensive, general training agency can only be equipped with 1-2 covers, at this moment, adopt the device that possesses the rehearsal function as profitable replenishment, can complement each other, better performance training effect.
Further, even if the drilling work is perfectly performed, the drilling work is performed before the actual operation, and accidents may be caused by carelessness of the operator, omission of some steps, or reversal of the steps during the actual operation, so that a guiding function in the actual operation process is necessary in addition to the drilling function and the guiding in the drilling process.
At present, in the market, a device for speech guidance of drilling or practice is lacked, only in certain scenes, some drawing boards are adopted, an operator writes a correct operation order according to the drawing boards, and misoperation is prevented by strict organization measures and step operation; the drawing boards are often limited in function, and only correspond to the drawing functions, and misoperation occurs in the actual operation process.
