Description

A kind of motor speed temperature control table

Technical field

The utility model relates to a kind of electronic control system, particularly, relates to a kind of motor speed temperature control table.

Background technology

The tachometric survey of existing machinery equipment is: by the pulse signal that the transducer that connects on the rotation axis is sent, deliver to single-chip microcomputer, realize that in conjunction with electronic circuit rotating speed shows through computing.Its shortcoming is, can only measure the rotating speed of rotation axis, lacks supporting with it temperature-control circuit design, so along with load strengthens, the time lengthening, the corresponding raising of temperature is to the damage that to a certain degree will cause plant equipment.

The utility model content

Technical problem to be solved in the utility model provides a kind of rotating speed temperature control table, effectively ensures the useful life of plant equipment and the safety of external control system.

The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of motor speed temperature control table, comprise power module, single-chip microcomputer, temperature sensor, velocity transducer, the motor speed control board, maximum temperature is set control board, display, described motor speed control board links to each other with motor with power module respectively, described maximum temperature is set control board and is linked to each other with power module, be core with the single-chip microcomputer, described power module, velocity transducer, temperature sensor, the motor speed control board, maximum temperature is set control board, display links to each other with single-chip microcomputer respectively, described motor speed control board is adjusted rotating speed of motor, velocity transducer and temperature sensor place motor internal respectively, velocity transducer sends the rotating speed of motor signal that collects and temperature sensor to single-chip microcomputer with the temperature signal of the motor that collects, in conjunction with design of electronic circuits, single-chip microcomputer shows rotating speed of motor and temperature by display through computing; Described temperature sensor sends detected motor temperature signal to single-chip microcomputer, single-chip microcomputer sends this temperature signal to maximum temperature and sets control board, maximum temperature is set control board the Temperature numerical that receives and the Temperature numerical of its internal preset is compared, the temperature that sends single-chip microcomputer to when temperature sensor surpasses maximum temperature when setting the default temperature of control board, then single-chip microcomputer is sent control signal to the motor speed control board, stop motor rotation, treat temperature drop to default temperature once after, single-chip microcomputer is sent control signal to the motor speed control board, adjusts motor by the motor speed control board and restarts.

The beneficial effects of the utility model are: by a kind of instrument that can show that rotating speed again can displays temperature is provided, avoid the various serious consequences that cause because motor temperature is too high, thereby guaranteed the safe operation of whole mechanical system.
