Description
Technical field
The present invention relates to circuit structure, is concretely that height of table top adjusts circuit.
Background technology
The appearance of smart home brings for Modern Live and conveniently, comfortably experiences.The meal used in current family
Table, and desk, the conference table etc. of company, most height of table top are all uncontrollable, this people to different heights
Always make one to feel that height of table top is improper when in use, it is especially larger in the kinsfolk of all ages and classes or some height gaps
People when using at the same time the problem it is more obvious.Therefore one kind is needed to be about to height of table top certainly according to different users' height
The scheme being adjusted.Meanwhile another situation is, the area in south etc. without heating, when indoor temperature is relatively low, desktop
Temperature is relatively low, so when people using when hand is put can not feel well on the table.
The content of the invention
The present invention provides a kind of height of table top to adjust circuit, and it is high can to adjust suitable desktop according to different users
Degree, and desktop can also be heated.
The height of table top of the present invention adjusts circuit, have the ultrasonic wave transtation mission circuit that is connected with the corresponding ports of microcontroller and
Ultrasonic wave receiving circuit, and motor of the control port of microcontroller for controlling desktop lifting mechanism is connected to, described
Ultrasonic wave is connected by No. six phase inverters in ultrasonic wave transtation mission circuit and module occurs, pass through in corresponding ultrasonic wave receiving circuit
Ultrasonic wave is received after chip receives the ultrasonic wave that ultrasonic wave generation module is sent and connected by the output terminal of ultrasonic wave reception chip
To microcontroller.
Most numbers that ultrasonic wave transtation mission circuit can be used according to desk be correspondingly arranged on it is multiple, by ultrasonic wave send electricity
Road is arranged on desktop central, sends ultrasonic wave to the people around desktop respectively, is returned if ultrasonic wave receiving circuit can receive
The ultrasonic wave returned, ultrasonic wave transtation mission circuit just move up the distance of setting, such as 1cm, launch again.If ultrasonic wave receives electricity
Road is not received by the ultrasonic wave of return, and ultrasonic wave receiving circuit then exports a height value received to microcontroller.It is logical
Relative altitude of the desktop with corresponding people can be calculated by crossing Pythagorean theorem.The height of owner and desktop are added up/total number of persons obtains
To a data, this data is subtracted into default height value, such as 30cm, just applies to current proprietary height of table top,
This height subtracts the original height of desktop again, is exactly the height that desktop needs to be raised and lowered.According to the desktop needs calculated
The height being raised and lowered, microcontroller control motor to carry out lifting/lowering to desktop.
Further, the signal input part of microcontroller is also associated with the temperature detection with temperature sensor arranged on desktop
Circuit；Microcontroller is also associated with heater circuit, the base stage of the output terminal connection PNP triode of microcontroller in heater circuit, and
Heating module is connected by the collector of PNP triode, the transmitter of PNP triode connects power supply.Examined by temperature sensing circuit
Survey desktop temperature, if temperature be less than microcontroller in default threshold value, microcontroller can control heater circuit to desktop into
Row heating.
Further, the relay of control heating module is additionally provided with heater circuit, can artificial hand by relay
The on/off of dynamic control heater circuit.
Further, the clock end of microcontroller is connected with crystal oscillator, and clock sequence number is provided for whole circuit.
The height of table top of the present invention adjusts circuit, suitable height of table top can be adjusted according to different users, with suitable
The height of all users is closed, and desktop can also be heated when desktop temperature is too low, improves the comfort level of user.
Embodiment with reference to embodiments, is described in further detail the above of the present invention again.
But the scope that this should not be interpreted as to the above-mentioned theme of the present invention is only limitted to following example.Think not departing from the above-mentioned technology of the present invention
In the case of thinking, the various replacements or change made according to ordinary skill knowledge and customary means, should all be included in this hair
In bright scope.
Brief description of the drawings
Fig. 1 is the circuit diagram that height of table top of the present invention adjusts circuit.
Embodiment
The height of table top of the present invention adjusts circuit as shown in Figure 1, has and is connected with the corresponding ports of 89C51 type microcontrollers U1
Ultrasonic wave transtation mission circuit and ultrasonic wave receiving circuit, and be connected to microcontroller U1 control port be used for control desktop to lift
The motor B1 of mechanism.The ultrasonic wave transtation mission circuit is corresponding with the quantity of user equipped with 4~8.Sent in ultrasonic wave
Ultrasonic wave is connected by SN74HC04 Xing No. six phase inverters in circuit module P1 occurs, in corresponding ultrasonic wave receiving circuit
Receive chip J1 by the ultrasonic wave of CX20106A types and receive after the ultrasonic wave of module P1 transmissions occurs for ultrasonic wave and pass through ultrasonic wave
The output terminal OUT for receiving chip J1 is connected to microcontroller U1.The promising whole circuit of clock end connection of microcontroller U1 provides clock
The crystal oscillator Y1 of sequence.
In order to improve the comfort of user in low temperature, the signal input part of microcontroller U1 is also associated with arranged on desktop
Temperature sensing circuit with temperature sensor J2；Microcontroller U1 is also associated with heater circuit, the microcontroller U1 in heater circuit
Output terminal connection PNP triode Q4 base stage, and the collector for passing through PNP triode Q4 connects tri- pole of heating module J3, PNP
The transmitter of pipe Q4 meets power supply VCC.The relay K1 of control heating module J3 is additionally provided with heater circuit, relay can be passed through
Device K1 controls the on/off of heater circuit manually.
Ultrasonic wave transtation mission circuit is arranged on desktop central, ultrasonic wave is sent to the people around desktop respectively, if ultrasonic
Ripple receiving circuit can receive the ultrasonic wave of return, and ultrasonic wave transtation mission circuit just moves up 1cm, launches again.It is if super
Acoustic receiver circuit is not received by the ultrasonic wave of return, and ultrasonic wave receives chip J1 and then exports a height value received
To microcontroller U1.Relative altitude of the desktop with all corresponding people can be calculated by Pythagorean theorem.Owner and the height of desktop
Add up/total number of persons obtains a data, this data is subtracted 30cm, current proprietary height of table top is just applied to,
