Description

Container measuring system and base control device thereof

The invention relates to a measuring system, in particular to a container measuring system and a base control device thereof.

Electronic scales are a common measuring device. When an object is placed on the electronic scale, the electronic scale can measure the weight of the object.

Taking the scenario of brewing coffee as an example, the user can place the measuring cup on the electronic scale and pour coffee beans into the measuring cup, and at the same time the user can observe the weight data displayed on the electronic scale to know the amount of coffee beans used; or the user can place the coffee pot on the electronic scale, and there are filter paper and coffee powder on the top side of the coffee pot. The user can take the hand pouring pot on top of the coffee pot, and pour water on the filter paper to brew the coffee powder, and at the same time observe the weight data displayed on the electronic scale to know the water output of the hand pouring pot.

However, it is known that electronic scales simply display weight data and have relatively simple functions without other additional functions, which limits their use.

In view of this, the main purpose of the present invention is to provide a container measuring system and a base control device thereof, in order to overcome the shortcoming of the conventional electronic scale that only displays weight data.

The novel container measurement system includes: A base control device, including: A weighing sensor for generating a sensing signal; A first display; A first transmission module; and A base controller, electrically connected to the weighing sensor, the first display and the first transmission module. When the base controller receives the sensing signal, the base controller generates a measurement information according to the sensing signal, and transmits the measurement information to the outside through the first transmission module according to a control signal; and A container control device, connected to the base control device, including: A second display; A posture sensor; A second transmission module, connected to the first transmission module to receive the measurement information; and A container controller is electrically connected to the second display, the posture sensor and the second transmission module. The container controller calculates information based on an initial value and the measurement value of the posture sensor, and controls the second display to display the information, wherein the initial value corresponds to the measurement information received through the second transmission module.

The novel base control device includes: A weighing sensor for generating a sensing signal; A display; A transmission module; and A base controller electrically connected to the weighing sensor, the display and the transmission module. When the base controller receives the sensing signal, the base controller generates measurement information according to the sensing signal, and transmits the measurement information to the outside through the transmission module according to a control signal.

The base control device of the present invention can be combined with a base, and the base controller can transmit the measurement information externally. In other words, the combination of the base control device and the base is equivalent to an electronic scale that can transmit information externally. Different from the conventional electronic scale that simply displays weight data, the present invention has functions that conventional electronic scales cannot achieve, and the measurement information transmitted externally can be used for different purposes. In the present container measurement system, the container control device can receive the measurement information from the base control device, and calculate and display the relevant information. Therefore, the practicality of the present container measurement system is greatly improved by the coordinated operation of the base control device and the container control device.

Please refer to FIG. 1 and FIG. 2 , an embodiment of the novel container measuring system includes a base control device 10 and a container control device 20 .

The base control device 10 is provided on a base 100 for carrying a container 200. That is, the base 100 and the base control device 10 can form an electronic scale. In one embodiment, the base 100 can be a base with a temperature control function.

The base control device 10 includes a weighing sensor 11, a display (hereinafter defined as a first display 12), a transmission module (hereinafter defined as a first transmission module 13) and a base controller 14. The weighing sensor 11 can be, for example, a load cell. The load cell can be a product available on the market. The types of load cells include photoelectric, hydraulic, electromagnetic, capacitive, magnetic pole type, vibration, gyro and resistance strain. The load cell can be set on the top side of the base 100. The first display 12 is used to provide information display function. The first display 12 can be, for example, a flexible display, a liquid crystal display, a seven-segment LED display or other types of displays. The first transmission module 13 is an electronic circuit module with wireless communication function. For example, the first transmission module 13 can be a Bluetooth module. The base controller 14 mainly provides data calculation and control functions. For example, the base controller 14 can be a microcontroller circuit module (MCU circuit module) and includes components such as a control unit, a memory, a timer, an analog-to-digital converter, an input/output (I/O) interface, etc., but is not limited to this. In the base controller 14, the control unit can be a microcontroller chip, and the timer can be realized by the clock software function of the control unit itself. The base controller 14 is electrically connected to the weighing sensor 11, the first display 12 and the first transmission module 13.

As mentioned above, the weighing sensor 11 takes the load cell as an example, and the working principle of the load cell is common knowledge in the relevant technical field. In short, when an object is placed on the base 100, the entire weight of the object will act on the load cell, and the load cell will deform elastically at this time, and the output voltage of the load cell will change with its own deformation, wherein the output voltage of the load cell is the sensing signal S1 generated by the weighing sensor 11. It is understandable that the base controller 14 can convert the output voltage of the load cell into a measurement information M1 after analog/digital conversion, and the measurement information M1 can be a weight value, and the measurement information M1 includes the total weight of the object sensed by the weighing sensor 11. That is, when the amount of liquid contained in the container 200 is greater, the deformation of the load cell is greater, resulting in a greater weight value of the measurement information M1. Therefore, when the base controller 14 receives the sensing signal S1 from the weighing sensor 11, the base controller 14 generates the measurement information M1 according to the sensing signal S1. For example, the base controller 14 may have a built-in voltage and weight comparison table. The base controller 14 may correspond the output voltage of the load cell to a certain weight value by looking up the table to generate the measurement information M1. In the embodiment of the present invention, the base controller 14 transmits the measurement information M1 to the outside through the first transmission module 13 according to a control signal S2; conversely, when the base controller 14 does not receive the control signal S2, the base controller 14 controls the first display 12 to display the measurement information M1 without transmitting the measurement information M1 to the outside through the first transmission module 13. In the above, the generation method of the control signal S2 will be described later.

The container control device 20 is provided in the container 200, and includes a display (hereinafter defined as a second display 21), a posture sensor 22, a transmission module (hereinafter defined as a second transmission module 23) and a container controller 24. The second display 21 is used to provide information display function, and the second display 21 can be, for example, a flexible display, a liquid crystal display, a seven-segment display of a light-emitting diode, or other types of displays. The posture sensor 22 can be an angle sensor, and the angle sensor can adopt an inductive, potentiometer or optical angle sensor available on the market. The second transmission module 23 is an electronic circuit module with wireless communication function, and the second transmission module 23 and the first transmission module 13 can be connected to each other for information transmission. For example, the second transmission module 23 can also be a Bluetooth module, so the second transmission module 23 can receive the measurement information M1 from the first transmission module 13. The container controller 24 mainly provides data calculation and control functions. For example, the container controller 24 can be a microcontroller circuit module (MCU circuit module) and includes components such as a control unit, a memory, a timer, an analog-to-digital converter, an input/output (I/O) interface, etc., but is not limited thereto. In the container controller 24, the control unit can be a microcontroller chip, and the timer can be realized by the clock software function of the control unit itself. The container controller 24 is electrically connected to the second display 21 , the posture sensor 22 and the second transmission module 23 .

Please refer to Figures 1 and 3. In one embodiment, the container 200 includes a body 201, and the body 201 can be used to hold liquid food or non-food; for example, the body 201 can be a pot, a bottle, a can, a cup, a bowl, a pot, a basin or a bucket; for example, the liquid food can be water, oil, tea, wine, coffee, milk, juice, soup or seasoning (such as soy sauce, vinegar... etc.), and the liquid non-food can be alcohol or a chemical solution... etc.; for example, the material of the body 201 can be stainless steel, ceramics, plastic or glass. The container 200 may include a flow guide 202, which may be disposed on the side wall of the body 201 for pouring liquid. For example, the flow guide 202 may be a tubular body, an opening or a groove. The container 200 may include a grip 203, which may be a handle disposed on the side wall of the body 201 for the user to hold. In one embodiment, the grip 203 may be directly connected to and fixed to the body 201. Referring to the embodiment shown in FIG. 3 , the body 201 is a pot, the flow guide 202 is a slender spout (tubular body), the flow guide 202 is located opposite to the grip 203, and a container cover 204 (pot cover) is provided on the top side of the body 201.

As mentioned above, the container control device 20 is provided for being arranged in the container 200. For example, the container control device 20 can be arranged in the body 201 or the gripping portion 203 of the container 200. As shown in the embodiment of FIG. 4 (a partial top view of the container 200), the second display 21 is arranged on the top side of the gripping portion 203. For example, the gripping portion 203 can include a tubular body, and the posture sensor 22, the second transmission module 23 and the container controller 24 can be arranged in the accommodation space in the grip portion 203, wherein the posture sensor 22 can be arranged flatly in the grip portion 203; in another feasible embodiment, the posture sensor 22 can also be arranged flatly in the sandwich layer at the bottom of the body 201 (not shown in the figure), and a battery can be arranged in the sandwich layer to supply power to the posture sensor 22. On the other hand, a power unit 25 can be arranged in the grip portion 203, and the power unit 25 is electrically connected to the container control device 20 to provide working power, and the container controller 24 can also control the second display 21 to display the battery power of the power unit 25.

In the present novel embodiment, the attitude sensor 22 takes an inductive angle sensor as an example. The attitude sensor 22 may be a gyroscope chip, and the working principle of the gyroscope chip is common knowledge in the relevant technical field. In short, the output signal S3 of the attitude sensor 22 may include a first voltage signal, a second voltage signal and a third voltage signal to the container controller 24. Please refer to Figure 3. The first voltage signal corresponds to the angular velocity of a first sensing axis (Pitch), the second voltage signal corresponds to the angular velocity of a second sensing axis (Roll), and the third voltage signal corresponds to the angular velocity of a third sensing axis (Yaw). These voltage signals can reflect the attitude of the container 200. When the container 200 is in a horizontal state, the first sensing axis (Pitch) and the second sensing axis (Roll) form a horizontal plane, and the third sensing axis (Yaw) is perpendicular to the horizontal plane. It is understandable that each voltage signal can correspond to an angular velocity measurement value after being converted and sampled by an analog/digital device. The unit of the angular velocity measurement value is dps (degree per second). The container controller 24 can integrate the angular velocity measurement value corresponding to the first voltage signal with respect to time to obtain an angle value θ as shown in FIG. 5 . The angle value θ is the tilt angle of the container 200 relative to the horizontal plane. The angle value θ corresponds to the tilt angle of the container 200 when pouring liquid into the cup 30.

Regarding the generation method of the control signal S2, please refer to FIG. 6 . In one embodiment, the base control device 10 may include a reader 15, which is disposed on the base 100. The base controller 14 is electrically connected to the reader 15. For example, the reader 15 may be an RFID reader, and correspondingly, the container 200 may be provided with an RFID tag. When the container 200 is placed on the base 100, the reader 15 can read the information of the RFID tag. For example, the reader 15 may be disposed on the top side of the base 100, and the RFID tag may be disposed on the bottom side of the container 200. Therefore, when the container 200 is placed on the base 100, the base controller 14 not only generates the measurement information M1, but also receives the information of the RF tag from the reader 15 as the control signal S2, and then transmits the measurement information M1 to the container control device 20 through the first transmission module 13. In contrast, when the base controller 14 does not receive the control signal S2, it means that the container 200 has not been placed on the base 100, so the base controller 14 only controls the first display 12 to display the measurement information M1 and does not transmit the measurement information M1 through the first transmission module 13.

In the embodiment of the present invention, the container controller 24 calculates information M2 based on an initial value and the measurement value of the posture sensor 22, and controls the second display 21 to display the information M2, wherein the initial value corresponds to the measurement information M1 received through the second transmission module 23. The following example illustrates how the initial value, the measurement information M1, and the information M2 are generated.

1. Initial value

The initial value refers to the amount of liquid currently contained in the container 200 before pouring the liquid out of the container 200 each time. In one embodiment, the memory of the container controller 24 can preset a container net weight value, wherein, when the empty container 200 that has not yet contained liquid is placed on the base 100 for weighing, the measurement information M1 generated by the base controller 14 can correspond to the container net weight value. When using the container 200, the container controller 24 can determine whether the user has just picked up the container 200. If so, the container controller 24 will deduct the container net weight value from the weight value of the measurement information M1 currently received through the second transmission module 23, which is equal to the initial value, and the initial value is equal to the amount of liquid contained in the container 200. On the contrary, if the user has not picked up the container 200, the container controller 24 does not calculate the initial value.

Regarding the means by which the container controller 24 determines whether the user has just picked up the container 200, in one embodiment, when the container controller 24 determines that the angle values of the three sensing axes Pitch, Roll, and Yaw of the posture sensor 22 are 0 degrees, respectively, indicating that the container 200 is in a flat state, it is determined that the user has not picked up the container 200. In addition, when the container controller 24 determines that at least one of the angle values of the three sensing axes Pitch, Roll, and Yaw of the posture sensor 22 is not 0 degrees, it means that the user has just picked up the container 200, so as to start the calculation of the initial value. When the user puts down the container 200 and keeps the container 200 in a horizontal static state, when the container controller 24 determines that the duration of the container 200 being put down reaches a threshold time, for example, when the container controller 24 determines that the angle values of the three sensing axes Pitch, Roll, and Yaw of the posture sensor 22 are 0 degrees respectively and continue to reach the threshold time, the container controller 24 returns the initial value to zero; wherein the threshold time is a preset value, for example, it can be 1.5 seconds. In another embodiment, please refer to Figure 6, the container controller 24 can be electrically connected to a ball switch 26, and the ball switch 26 can be set on the grip 203 or the body 201 of the container 200. It can be understood that the conductive state (ON) and the open state (OFF) of the ball switch 26 correspond to the posture of the ball switch 26. For example, when the ball switch 26 is in a flat state, the ball switch 26 can be in an open state (OFF), and when the ball switch 26 is tilted at a specific angle, the ball switch 26 can be in a conductive state (ON). Therefore, when the user just picks up the container 200 and tilts it at the specific angle, the container controller 24 can determine the state change of the ball switch 26 and then start the calculation of the initial value or reset it to zero.

After the initial value is reset to zero, the container 200 can be placed back on the base 100, and as mentioned above, the reader 15 of the base control device 10 reads the information of the RF tag of the container 200 as the control signal S2, and the base controller 14 further transmits the measurement information M1 to the container control device 20 for the container controller 24 to calculate the initial value.

2. Data stored in the memory of the container controller 24

The memory of the container controller 24 stores a comparison table, which may include values of multiple reference liquid volumes and different liquid discharge reference values corresponding to each reference liquid volume at different tilt angles, each of which is an instantaneous flow rate. For ease of understanding, for example, the reference liquid volume of the comparison table may include 300ml (milliliters) and 250ml, and the tilt angles corresponding to 300ml may include 10 degrees and 15 degrees. The liquid discharge reference value corresponding to 10 degrees may be 2ml/s (milliliters/second), and the liquid discharge reference value corresponding to 15 degrees may be 2.2ml/s; the tilt angles corresponding to 250ml may include 25 degrees and 30 degrees, and the liquid discharge reference value corresponding to 25 degrees may be 2ml/s, and the liquid discharge reference value corresponding to 30 degrees may be 2.2ml/s. Regarding the method of establishing the reference table, the user can pre-fill the body 201 with 300 ml of liquid, then pour the liquid into a measuring cup, and at the same time observe and record the angle value θ output by the posture sensor 22 corresponding to the first voltage signal, so as to obtain the reference value of the liquid discharge of the body 201 filled with 300 ml of liquid at different tilt angles. The reference tables of other benchmark liquid volumes, tilt angles and liquid discharge reference values can be inferred in the same way.

In addition to the embodiment of the reference table, in another embodiment, the memory of the container controller 24 can also store multiple reference liquid volumes and a function corresponding to each reference liquid volume, the input of the function is the tilt angle, and the output of the function is the liquid discharge reference value, wherein the function can be derived based on the data of the reference table. For example, the function can be a linear function or a nonlinear function. For ease of understanding, the linear function is taken as an example, and the linear function can be expressed as: y=ax+b, wherein y is the liquid discharge reference value and x is the tilt angle.

3. Real-time tilt

Please refer to FIG. 5 , the user can pour the liquid in the container 200 into a cup 30. Since the first voltage signal output by the posture sensor 22 corresponds to the angular velocity of the first sensing axis (Pitch), the container controller 24 can integrate the angular velocity measurement value of the first voltage signal with respect to time to obtain an angle value θ, which is the instantaneous tilt angle of the container 200 relative to the horizontal plane.

4. Calculation of liquid output

In a pouring process, the container controller 24 obtains a liquid discharge reference value according to the initial value and the real-time tilt angle through a table lookup method or the functional formula, wherein the container controller 24 can compare the initial value and the real-time tilt angle in the reference table. For example, when the initial value is 300 ml and the real-time tilt angle is 10 degrees, the container controller 24 can correspond to a liquid discharge reference value of 2 ml/s in the reference table. It can also be understood that when the initial value and the real-time tilt angle do not have corresponding reference liquid volume and tilt angle in the reference table, the container controller 24 can obtain the liquid discharge reference value through interpolation, and interpolation is common knowledge in the relevant technical field and will not be described in detail here. Or in another embodiment, the container controller 24 can compare the reference liquid volume and its function that match the initial value, and then substitute the real-time tilt angle into the function to obtain the liquid discharge reference value.

The container controller 24 can integrate the liquid discharge reference value with respect to time to obtain a first liquid discharge amount. For example, the container controller 24 obtains a liquid discharge reference value Y1 at time t1. The first liquid discharge amount can be expressed as follows:

In the above formula, time tx is the duration from time t1 to the next reference value of liquid discharge. Then, the container controller 24 can deduct the first liquid discharge amount from the initial value to obtain a real-time liquid volume, which corresponds to the current amount of water in the body 201. For example, if the initial value is 300 ml and the first liquid discharge amount is 10 ml, the real-time liquid volume is 290 ml.

Similarly, the container controller 24 obtains another liquid discharge reference value according to the real-time liquid volume and the real-time tilt angle through a table lookup method or a function expression, and integrates the other liquid discharge reference value with respect to time to obtain another liquid discharge volume (hereinafter referred to as the second liquid discharge volume). The second liquid discharge volume is, for example, 12 ml. The container controller 24 can deduct the second liquid discharge volume from the real-time liquid volume to update the real-time liquid volume. The updated real-time liquid volume is, for example, 278 ml. Further, the container controller 24 obtains another liquid discharge reference value by using a table lookup method or a function expression for the instant liquid volume (278 ml) and the instant tilt angle, and integrates the another liquid discharge reference value with respect to time to obtain another liquid discharge volume (hereinafter referred to as a new second liquid discharge volume, for example, 13 ml). The container controller 24 can deduct the new second liquid discharge volume (13 ml) from the instant liquid volume (278 ml) to update the instant liquid volume again. The instant liquid volume after the update is, for example, 265 ml. Similarly, during the pouring process, as the amount of water in the body 201 gradually decreases, the real-time liquid volume is also continuously updated accordingly. The container controller 24 obtains multiple liquid discharge reference values through a table lookup method or a function expression based on the continuously updated real-time liquid volume and the real-time tilt angle, and then integrates the time to obtain multiple second liquid discharge volumes.

5. Calculation and display of cumulative liquid output

As described above, the container controller 24 calculates information M2 based on the initial value and the measured value of the posture sensor 22, and controls the second display 21 to display the information M2. The information M2 is, for example, a cumulative liquid output, but is not limited thereto. The cumulative liquid output is the cumulative value of the first liquid output and the plurality of second liquid outputs during the pouring process. For example, when the container controller 24 calculates a first liquid output of 10 ml at a first time, the second display 21 can be controlled to display the information M2. 1 displays a cumulative liquid output of 10 ml; when the container controller 24 calculates a second liquid output of 12 ml at a second time, 10 ml and 12 ml are accumulated, and the second display 21 is controlled to display a cumulative liquid output of 22 ml; when the container controller 24 calculates a second liquid output of 13 ml at a third time, 22 ml and 13 ml are accumulated, and the second display 21 is controlled to display a cumulative liquid output of 35 ml, and so on. Therefore, the user can view the cumulative liquid output displayed on the second display 21, and the cumulative liquid output serves as objective reference information for the user to effectively grasp the liquid outflow state. The display format of the second display 21 displaying the cumulative liquid output can be a number or a pattern.

6, the container controller 24 can be electrically connected to a reminder 27, which can be, for example, an indicator light or a speaker, and can give a reminder to the user with light or sound. The reminder 27 can be set on the container 200, for example, on the body 201 or the grip 203. The container controller 24 can be electrically connected to a switch element 28, which can be, for example, a touch switch, a button switch, or a micro switch, to trigger the container controller 24 to implement a specific function.

The following takes the application of the present invention in the context of brewing coffee as an example. Factors that affect the taste of hand-brewed coffee may include the brewing angle. Based on the measurement information of the posture sensor 22, the container controller 24 can determine whether the angle value of each sensing axis (Pitch, Roll, Yaw) is greater than a corresponding threshold value. If so, the container controller 24 can drive the prompter 27 to issue a prompt to timely remind the user that the brewing angle is inappropriate, wherein the threshold value of each sensing axis Pitch, Roll, Yaw is a default value. On the other hand, factors that affect the taste of hand-brewed coffee may also include brewing time. The switch element 28 may be used to trigger the timing function of the container controller 24. For example, when the container controller 24 determines that the switch element 28 is pressed, the container controller 24 may start the timing function and drive the second display 21 to display a timing time, so that the user can effectively grasp the brewing time. On the other hand, the container controller 24 can store at least one liquid flow threshold value, and determine the size of the accumulated liquid output and the at least one liquid flow threshold value, and drive the prompt mode of the prompter 27 according to the determination result. For example, the at least one liquid flow threshold value can include 100ml and 150ml. When the container controller 24 determines that the accumulated liquid output is greater than 100ml and less than 150ml, the prompter 27 can be controlled to emit a prompt sound such as "beep"; when the container controller 24 determines that the accumulated liquid output is greater than 150ml, the prompter 27 can be controlled to emit two consecutive prompt sounds such as "beep" and "beep", so as to assist the user in reminding the flushing volume through sound.

As described above, the second display 21 can display the information such as the amount of liquid poured, the pouring time, and the battery level as an auxiliary guide. In addition, through the operation of the container controller 24, it has the advantages of high precision, rapid response, and high stability. Taking the application in the scenario of brewing coffee as an example, when the user picks up the container 200 to pour water, the user can directly observe the information displayed on the second display 21 on the container 200 to know how much water has been poured, helping the user to more conveniently control the water output, flow rate and pouring angle, rather than relying entirely on the user's subjective personal feel, so as to improve the quality and taste of hand-brewed coffee. In addition, the new type is also simple and easy to use, convenient to operate, and very suitable for use at home, coffee shops and other places. On the other hand, the user may also place a coffee bean measuring cup on the base 100. Since the coffee bean measuring cup is not provided with the radio frequency tag as described above, the base controller 14 does not receive the control signal S2 and only controls the first display 12 to display the measurement information M1. At this time, the combination of the base 100 and the base control device 10 is equivalent to an electronic scale for the user to weigh the coffee beans.

Please refer to FIG. 6 , the power unit 25 may include a rechargeable battery 251 , and the rechargeable battery 251 is electrically connected to the container control device 20 to supply working power, wherein the rechargeable battery 251 may be charged by at least one of wireless charging and wired charging.

For wireless charging, the power unit 25 may include a wireless charging receiver 252, which is electrically connected to the rechargeable battery 251. Correspondingly, please refer to FIG. 7 , the base 100 is provided with a wireless charging plate 253. When the container 200 is placed on the base 100, the position of the wireless charging plate 253 corresponds to the position of the coil of the wireless charging receiver 252, so that the coil of the wireless charging receiver 252 can sense and receive the output magnetic field of the wireless charging plate 253 and convert it into a charging power source to charge the rechargeable battery 251. For wired charging, please refer to FIG. 6 , the power unit 25 can be electrically connected to a power adapter 254 through a physical charging cable or connector, and the power adapter 254 is used to convert a mains AC power source into a charging power source to charge the rechargeable battery 251. The characteristic of wireless charging is that the container 200 can be directly charged as long as it is placed on the base 100, which is more convenient to use.

Please refer to FIG. 6 , the container controller 24 can be connected to an electronic device 40. For example, the container controller 24 can be electrically connected to a wireless transmission module 29 to establish a connection with the electronic device 40 through the wireless transmission module 29 to perform data transmission. The wireless transmission module 29 can be, for example, a Wi-Fi module or a Bluetooth module, and the electronic device 40 can be, for example, a user's smart phone or tablet computer. In this way, the container controller 24 can transmit the accumulated liquid volume, time and other related data to the electronic device 40, and the electronic device 40 can also store these data as historical records, so that the user can grasp the situation of hand-brewed coffee through the electronic device 40.
