Although highly sensitive sensors can be used to detect users, the detection range of the sensors is limited. Especially for larger tables or special-shaped tables, when people sit close to the table, they often exceed the detection range of a single sensor.

[0019] Various exemplary embodiments, features and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.
[0020] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.
[0021] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present disclosure.
[0022] In order to facilitate those skilled in the art to understand the technical solution provided by the embodiments of the present disclosure, the technical environment in which the technical solution is implemented is described below.
[0023] The smart lifting table system realizes intelligent control by installing sensors on the table to detect whether there is someone in front of the table in real time. The sensor is usually installed under the table and connected to the motor driver together with the hand control panel and indicator light. When the user sits at the table, the sensor detects the presence of the human body and transmits the information to the indicator light and hand controller through the motor controller. When the system detects someone, it will automatically turn on the atmosphere light and start counting the sitting time. When the user leaves the table, the sensor detects that there is no one, notifies the indicator light and hand controller to turn off the atmosphere light and stop counting.
[0024] like Figure 1 As shown in the figure, the traditional smart table is connected in a way that the hand control panel, sensors and indicator lights are directly connected to the motor driver. In addition to controlling and driving the lifting motor, the motor driver simply processes the operation of the sensor and hand control panel as an auxiliary function, and indicates the occupancy status or sedentary status to the user through the indicator light. This connection method is greatly restricted by the design of the motor driver, and generally cannot provide a more flexible indicator light control strategy, nor can it expand multiple sensors for more complex table types.
[0025] In order to solve the above technical problems, the embodiment of the present disclosure provides an improved lifting table system for a smart table, such as Figure 2 As shown, multiple monitoring modules connected in series are set between the hand control panel and the motor drive module. The module is integrated based on sensors, lights and control units. A certain number of monitoring modules can be connected in series according to actual needs. One monitoring module can be regarded as a sensor node, which is equivalent to a certain number of sensors connected in series, so as to adapt to different detection ranges. The traditional smart table system usually has only one sensor, which is suitable for small tables, but is prone to misjudgment on large tables. The improved lifting table system provided by the embodiment of the present disclosure increases multiple monitoring modules based on sensors to adapt to the size of the actual smart table, and connects these monitoring modules in series to integrate the results of all monitoring modules. It can not only expand the detection range and sensitivity, but also accurately reflect whether there is a user near the smart table, effectively avoid misjudgment, and enhance the adaptability and expansibility of the lifting table system.
[0026] Now combined Figures 2 to 4 The lifting table system for a smart table provided in an embodiment of the present disclosure is schematically described. Figure 3 As shown, the lifting table system may include a hand control panel, a motor drive module, a plurality of monitoring modules connected in sequence and arranged on the smart table, and a plurality of lights. The plurality of monitoring modules are connected between the hand control panel and the motor drive. Each monitoring module includes a control unit, a sensor, an upper interface unit, and a lower interface unit.
[0027] Each sensor can be used to detect the presence of users within a preset range and send the first detection result to the control unit in the monitoring module. The preset range can generally be determined based on the specific position of the sensor on the smart table and the range that the sensor can actually detect. The first detection result indicates whether there is a user within the preset range. In some embodiments, the sensor in each monitoring module may be a millimeter wave radar sensor, which is a relatively advanced human body sensor that uses the echo of the human body to detect the movement of the human body and the micro-movement caused by breathing, so as to determine the presence of human bodies nearby. It should be noted that the users detected in the embodiments of the present disclosure can be living beings such as children and adults, or robots, so that the appropriate type of sensor can be selected according to actual needs.
[0028] Each upper interface unit can be used to forward the upstream results from the upstream module to the control unit in the monitoring module. The upstream module is the monitoring module or motor drive module that is the front of the two monitoring modules connected to the monitoring module where the upper interface unit is located, for example Figure 3 The upstream module of monitoring module 1 is monitoring module 2. Figure 3 The upstream module of the monitoring module n in is the motor drive module. The upstream result indicates whether there is a user around the smart table, which is determined by the upstream module that issues the upstream result.
[0029] Each lower interface unit can be used to forward the downstream results from the downstream module to the control unit in the monitoring module. The downstream module is the monitoring module or hand control panel behind the two monitoring modules connected to the monitoring module where the lower interface unit is located, for example Figure 3 The downstream module of the monitoring module 1 is the hand control panel. Figure 3 The downstream module of the motor driving module in is the monitoring module n. The downstream result indicates whether there is a user around the smart table, which is determined by the downstream module that issues the downstream result.
[0030] Each control unit (MCU) can be used to determine the user detection result according to the first detection result, the upstream result, and the downstream result, and turn on or off the light controlled by the monitoring module according to the user detection result. The number of lights controlled by a monitoring module is one or more. The user detection result indicates whether there is a user around the current smart table or whether the smart table is occupied by a user. Generally, if there is a user, the light is turned on, otherwise it is turned off.
[0031] In this way, multiple monitoring modules connected in series are set between the hand control panel and the motor drive module to expand the detection range. Each monitoring module can use the first detection result, the upstream result, and the downstream result to respectively determine the user detection result. Each monitoring module, that is, the sensor node, can independently and in real time calculate whether there is a user in front of the smart table, thereby determining the occupancy status of the entire table and realizing distributed state fusion and decision-making.
[0032] In the lifting table system, a decentralized distributed data fusion calculation method is used between each monitoring module, so that each monitoring module can independently calculate the user detection result. In order to achieve this goal, the state of each monitoring module in series, that is, each sensor node in the embodiment of the present disclosure can be represented by four state quantities. These four state quantities are the upstream result, downstream result, first detection result, and user detection result. Each state quantity can be represented by 1 for no user and 0 for user, or by 1 for user and 0 for no user. The specific setting can be flexible and corresponding reasonable logical operations can be set. If each state quantity is represented by 1 for no user and 0 for user, then Figure 3 The user detection result determined by the control unit in the monitoring module 2 is the result obtained by logically performing the first detection result obtained by its own sensor, the downstream result sent from the monitoring module 1, and the upstream result sent from the monitoring module 3; similarly, if each state quantity uses 0 to represent no user and 1 to represent a user, the logical AND operation can be changed to a logical OR operation to obtain the user detection result.
[0033] In addition to controlling the on and off of the lights, each monitoring module will also transmit information to the corresponding upstream modules and downstream modules, so that the information of each monitoring module can be synchronized and propagated in all monitoring modules. Each control unit can also be used to determine a first result based on a first detection result obtained by the sensor detection in the monitoring module where it is located and an upstream result sent by the upstream module of the monitoring module where it is located, and use the first result as a new upstream result and send it to the corresponding downstream module through the lower interface unit in the monitoring module. It can be seen that the new upstream result combines the first detection result obtained by the sensor detection and the previous upstream result. In this way, the upstream result transmitted between the two monitoring modules can indicate whether there is a user within the corresponding preset range of all upstream monitoring modules. For example, if each state quantity uses 1 to represent no user and 0 to represent a user, then Figure 3 The monitoring module 2 can perform a logical AND operation on the first detection result obtained by its own sensor and the upstream result sent from the monitoring module 3 to obtain a first result, and use the first result as a new upstream result and send the upstream result to the monitoring module 1. In this case, the result indicating the presence of a user can be passed down layer by layer through the logical AND operation. For another example, if each state quantity uses 0 to represent no user and 1 to represent the presence of a user, the logical AND operation can be changed to a logical OR operation, and the rest of the process is the same as the previous example, which will not be repeated here.
[0034] Each control unit can also be used to determine a second result based on the first detection result and the downstream result, and send the second result as a new downstream result to the corresponding upstream module through the upper interface unit in the monitoring module. It can be seen that the new downstream result is also a combination of the first detection result obtained by the sensor detection and the previous downstream result. In this way, the downstream result transmitted between the two monitoring modules can indicate whether there is a user within the corresponding preset range of all downstream monitoring modules. For example, if each state quantity uses 1 to represent no user and 0 to represent a user, then Figure 3 The monitoring module 2 can perform a logical AND operation on the first detection result obtained by its own sensor and the downstream result sent from the monitoring module 1 to obtain a second result, use the second result as a new downstream result and send the downstream result to the monitoring module 3. For another example, if each state quantity uses 0 to represent no user and 1 to represent a user, the logical AND operation can be changed to a logical OR operation, and the rest of the process is the same as the previous example, which will not be repeated here.
[0035] In some embodiments, each control unit may check the upstream result periodically (e.g., every 1 second). If no update is received within a certain period of time (e.g., 10 seconds), the upstream result is reset to 1 to indicate a default no-user state. Similarly, for the upstream result, each control unit may check the downstream result every 1 second. If no update is received within 10 seconds, the downstream result is reset to 1 to indicate a default no-user state.
[0036] In this way, four state quantities and a timing detection mechanism are introduced to optimize the state processing efficiency of the lifting table system, which not only reduces the complexity of the lifting table system, but also improves the response speed and stability.
[0037] Each monitoring module may also include a power supply circuit and an indicator light interface unit. Figure 4 As shown, each power supply circuit can be used to use external power input through the upper interface unit or the lower interface unit to power the monitoring module, such as the control unit and the sensor in the monitoring module. Figure 4 As shown, each power supply circuit can also be used to transmit external power to the lamp controlled by the monitoring module through the indicator light interface unit. If the upper interface unit is an interface unit connected to an external power supply, then Figure 4 As shown, the upper interface unit can also supply power to the lower interface unit. If the interface unit connected to the external power supply is a lower interface unit, the lower interface unit can also supply power to the upper interface unit. The indicator light interface unit can be a USB-C interface.
[0038] The most upstream motor drive module in the system can be used to drive the motor of the smart table to adjust the height of the smart table. Figure 3As shown, the upstream result sent by the motor driving module to the monitoring module n can be determined based on the driving condition of the motor itself. For example, if the motor driving module is in a normal working state, it is considered that it is driving the motor to adjust the height. At this time, it is considered that there is a user near the smart table. Therefore, the upstream result sent by the motor driving module to the monitoring module n is that there is a user around the smart table; if the motor driving module is in a non-working state, the upstream result sent at this time is that there is no user around the smart table.
[0039] The motor drive module can also transmit the motor information of the motor through each monitoring module to the hand control panel at the most downstream of the system. The motor information may include the current height of the smart table and / or the motor status. The motor drive module can also be used to send the motor information of the motor to the connected monitoring module (e.g. Figure 3 Each monitoring module can also be used to forward the received motor information to the downstream module, so that the motor information is transmitted to the hand control board through each monitoring module in turn, such as Figure 3 The hand control panel can be used to display the received motor information, making it easier for users to view relevant information.
[0040] In addition to displaying motor information, the hand control panel can also be used to display the status of each monitoring module, send light signals, send adjustment signals, etc. The light signals, adjustment signals, etc. sent by the hand control panel can be obtained in response to user operations. The light signal can be used to indicate the brightness and / or color of the indicator light. Taking the light signal as an example, the hand control panel can determine the corresponding light signal based on the input operation detected for the color of the light. Figure 3 As shown, the light signal sent by the hand control panel can be sent to each monitoring module to control each light. The hand control panel can also be used to send the light signal to the connected monitoring module. Each monitoring module can also be used to adjust the brightness and / or color of the controlled light according to the received light signal, and forward the light signal to the upstream module through the upper interface unit, such as Figure 3 The monitoring module 1 in the system controls the connected lights based on the light signal sent by the hand control panel and sends the light signal to the monitoring module 2, so that each monitoring module can control the corresponding light based on the light signal. In this way, in the multi-sensor node series mode, the two upper and lower interface units of the monitoring module are cleverly utilized to ensure that the light signal of the hand control panel can be effectively transmitted to each monitoring module. No matter how many monitoring modules are connected in series in the lifting table system, the light signal sent by the hand control panel can be directly transmitted to each monitoring module, which ensures the reliability and efficiency of the communication between the hand control panel and each monitoring module, and also ensures the flexibility and scalability of the lifting table system.
[0041] like Figure 3As shown, the adjustment signal for indicating the height of the smart table sent by the hand control panel can be transmitted all the way to the drive module through each monitoring module. The hand control panel can also be used to send the adjustment signal to the connected monitoring module. Each monitoring module can also be used to forward the received adjustment signal to the upstream module, so that the adjustment signal is transmitted to the motor drive module through each monitoring module in turn. The motor drive module can also be used to drive the motor of the smart table to work based on the adjustment signal to adjust the height of the smart table.
[0042] After the lifting table system is powered on, the MCU configures the detection distance and range of the millimeter wave radar sensor to ensure that the sensor can correctly detect the presence of users around the smart table. After the configuration is completed, the MCU enables communication between the upper interface unit and the lower interface unit. During normal operation, the MCU can read the output of the millimeter wave sensor every 1 second. If the output is high, it means that a user is detected. If the output is low, it means that no user is present. In this embodiment, the upper interface unit (i.e. Figure 2 The upper data interface in the data communication may include four power / signal lines, namely, a TX line for sending communication information, an RX line for receiving communication information, a VCC line for power input, and a GND line connected to the reference ground; the lower interface unit for data communication (i.e. Figure 2 The lower data interface in the upper interface unit may also include 4 power / signal lines similarly to the upper interface unit, the difference is that the VCC line is used for power output.
[0043] This lifting table system enhances the detection range by connecting multiple monitoring modules in series, and integrates and processes upstream and downstream messages and the first detection results of sensors through each control unit, while ensuring the transmission of the light signal of the hand control panel in each monitoring module. This not only enhances the function and flexibility of the system, but also optimizes the efficiency of sensor detection and state processing, thereby significantly improving the overall performance and user experience of the lifting table system. In this way, multiple monitoring modules can be cascaded according to actual needs to achieve a wide range of workstation occupancy detection.
[0044] The present disclosure also provides a smart table, including the above-mentioned lifting table system. In some embodiments, the smart table may also include a motor for adjusting the height of the smart table. In some embodiments, the specific implementation of the smart table provided by the present disclosure can refer to the description of the lifting table system embodiment above, and for the sake of brevity, it will not be repeated here.

Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
