Embodiment 1

[0041] Please refer to figure 1 and figure 2 , the intelligent table automatic rotation control method provided in this embodiment includes the following steps:

[0042] (1) Prepare an intelligent dining table automatic rotation control system, which is used by 8 people, including a control unit 1, a dining table body 2, a turntable 3 and a landscape column 10 arranged on the dining table body 2, and the control unit 1 includes a PLC Controller 11, positioning expansion module 12, servo actuator 13 and incremental rotary encoder 14, the servo actuator 13 includes a servo motor 131, the incremental rotary encoder 14 is coaxially installed with the turntable 3; the dining table body 2 is provided with a number of infrared sensing devices 4, the infrared sensing device includes an infrared emitting end 41 and an infrared receiving end 42, a reflective mirror 101 is provided on the landscape column 10, and the infrared rays emitted by each infrared emitting end 41 are reflected ...

Embodiment 2

[0062] The method provided by this embodiment and the first embodiment and the intelligent dining table are basically the same, the main difference is:

[0063] In the step (1), a torque sensor is provided at the lower end of the turntable 3, an electromagnetic clutch 6 and a rotary encoder 7 are arranged between the servo actuator 13 and the turntable 3, and the output shaft 1311 of the servo motor 131 is Be connected by drive shaft 8 with the turntable 3; Described step (5) also comprises the following steps:

[0064] (5.1) The PLC controller 11 constantly obtains the contact state signal output by the torque sensor;

[0065] (5.2) When the external torsion force on the turntable 3 causes the torque on the torque sensor to be greater than its limit torque, the normally open contact in the torque sensor is closed and the normally closed contact is disconnected, then the PLC controller 11 controls the electromagnetic clutch 3 contacts Separate, so that the output shaft 1311 o...

Embodiment 3

[0074] The method and the intelligent dining table provided in this embodiment are basically the same as those in Embodiment 1 or Embodiment 2, the main difference being:

[0075] It also includes step (6): preset the blocked time threshold T between the infrared transmitting end 41 and the infrared receiving end 42 by the PLC controller 11, and each time threshold T corresponds to a current pulse count value; Afterwards, the built-in high-speed counter of PLC controller 11 starts timing, and the blocking disappears, and the high-speed counter immediately stops timing to obtain the blocking time nT; then the servo actuator 13 controls the turntable 3 to rotate the angle corresponding to n current pulse count values.

[0076] Through the control method provided in this embodiment, when a wider range of rotation angles is required, it is only necessary to prolong the time for the shield to be placed between the infrared emitting end 41 and the infrared receiving end 42. If the in...

Abstract

The invention discloses an intelligent dining table automatic rotation control method which includes the steps: (1) preparing an intelligent dining table automatic rotation control system; (2) corresponding to a pulse counting value by a turntable rotating by one position; (3) receiving current infrared pulse signals transmitted by an infrared transmitting end in real time and transmitting the current infrared pulse signals to a PLC (programmable logic controller) by an infrared receiving end, comparing the current infrared pulse signals with standard infrared pulse signals by the PLC, judgingwhether the current infrared pulse signals are consistent with the standard infrared pulse signals or not, indicating existence of shield if not, calculating a current pulse counting value by the PLC, transmitting instructions to a positioning extension module and starting a servo motor and an incremental rotary encoder; (4) turning the turntable and the incremental rotary encoder at the same angular speed to generate two pulses with the phase difference of 90 degrees and determining a rotation direction; (5) turning the turntable in the determined rotation direction at an initial rotation speed by a corresponding angle. The invention further discloses an intelligent dining table implementing the method.

Description

technical field [0001] The invention relates to the technical field of smart home products, in particular to an intelligent dining table automatic rotation control method and the intelligent dining table. Background technique [0002] At present, the development of various smart homes is increasing day by day. Rotating dining table is a table commonly used in the Chinese catering industry at present. There are two main types of rotating dining table according to the operation mode: one is manual rotation and the other is automatic rotation. Manually rotating the dining table requires the diner to rotate the dining table by hand while eating, which is inconvenient to use. Compared with manual rotation, the automatic rotating table is a high-end product in this type of product. When the table rotation function is activated, the table will automatically rotate until the rotation is turned off. Although the automatic rotating dining table solves the shortcomings of rotating th...
