Description

A kind of intelligent self-balancing same table control circuit

Technical field

The utility model relates to autobalance same table technologies, control more particularly to a kind of intelligent self-balancing same table Circuit.

Background technique

With the raising of social and economic activities level, requirement of the people to the convenience and comfort of desk is higher and higher. Cost performance is high, stable drive, can the desk of automatic controlled height liked by consumer.The type of the automatic lifting table of existing market Based on mechanical, electrodynamic type, electric lifting table generally passes through two or three support columns and achives up and down, and generally deposits The shortcomings that be that each support column is easy to appear the inconsistent situation of adjustable height, autobalance can not be properly arrived at.

Utility model content

For this purpose, the utility model is to overcome above-mentioned technical problem, a kind of intelligent self-balancing same table control circuit is provided.

Then, the utility model provides following technical scheme:

A kind of intelligent self-balancing same table control circuit, including control chip, power supply circuit, motor-drive circuit and just Reversing controller circuit, the motor-drive circuit and forward and reverse controller circuitry are separately connected the control chip, institute Stating intelligent self-balancing same table control circuit further includes current detection circuit and motor position and velocity checking circuits, institute Current detection circuit is stated to be arranged in the motor-drive circuit to detect current of electric, the motor position and velocity measuring Circuit is arranged in motor and connects the control chip to detect the motor position and speed.

Specifically, the motor position and velocity checking circuits include there are two Hall sensor, and described two Halls pass Sensor is connected respectively to the control chip.

Preferably, the intelligent self-balancing same table control circuit further includes audible alarm circuit, the audible alarm Chip is controlled described in circuit connection.

The utility model beneficial effect is: a kind of control circuit for being able to achieve control desk etc. and freely adjusting height, knot Closing programming makes product have the function of balance lifting, defencive function, memory function etc., allows user according to the comfortable journey of oneself It spends and likes using desk.Meanwhile desk that different public arenas use is adapted to according to the height of different users and comfortable Freely adjust；Enhance user experience, improves service quality.

Fig. 1 is the circuit diagram of embodiment power supply circuit.

Fig. 2 is the circuit diagram of embodiment motor-drive circuit.

Fig. 3 is that embodiment controls chip connection circuit diagram.

Fig. 4 is that the forward and reverse controller circuitry of embodiment, motor position with velocity checking circuits connect circuit diagram.

Specific embodiment

In the following, the utility model is described in detail in conjunction with attached drawing.

A kind of intelligent self-balancing same table control circuit, including control chip, power supply circuit, motor-drive circuit, just Reversing controller circuit, current detection circuit, audible alarm circuit and motor position and velocity checking circuits, wherein power supply The circuit diagram of circuit controls chip connection circuit diagram referring to attached referring to attached drawing 2 referring to attached drawing 1, the circuit diagram of motor-drive circuit Fig. 3, forward and reverse controller circuitry, motor position and velocity checking circuits connect circuit diagram referring to attached drawing 4, control in the present embodiment Chip is single-chip microcontroller U1, and motor-drive circuit and forward and reverse controller circuitry are separately connected single-chip microcontroller U1, and current detection circuit is set It sets to detect current of electric in motor-drive circuit, motor position and velocity checking circuits are arranged in motor and connect list Piece machine U1 is to detect motor position and speed.

Specifically, as shown in Figs 1-4, power supply circuit is made of U4, VR1 and surrounding component；Motor-drive circuit is by crystal Pipe Q2-Q9, relay K1-K4 and surrounding component composition, forward and reverse controller are U3；Current detection circuit by resistance R9, R10, R19, R28, capacitor C15, C18 composition；Motor position and velocity checking circuits (are mounted on electricity by two Hall sensors J2 and J4 Inside machine), resistance R3, R4, R15, R16 and capacitor C13, C14, C16, C17 composition；Audible alarm circuit by buzzer LS1 and Drive transistor Q1 and surrounding component composition.

In the present embodiment, after intelligent self-balancing same table powers on (external 24V DC power supply), user passes through By the key that rises or falls being fixed on desktop face, single-chip microcontroller U1 receives push button signalling, output driving pwm signal, driving Motor operating, and be attracted by positive and negative controller U3 according to signal control tetra- relays of K1-K4 that rise or fall of single-chip microcontroller U1 Constitute motor forward or reverse.

In motor operation course, single-chip microcontroller U1 can recycle the signal waveform for reading and being passed back by Hall sensor, be calculated Speed and the position of motor operation are sorted out, the digital display tube being shown at desktop control button carries out height for user It adjusts and personal settings saves.Respective PWM driving letter is adjusted according to the speed of two motor operations and position simultaneously Number duty ratio, reaches the steady balance movement in desktop both sides.

In motor operation course, single-chip microcontroller U1 can recycle reading by the voltage value on current sensing resistor, calculate and arrange For operating current, then stop motor operating when safety value of the operating current detected beyond setting, while driving buzzer Issue alarm.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
