[0036] In order to make the description of the present disclosure more detailed and complete, reference may be made to the attached drawings and various embodiments described below, in which the same numbers represent the same or similar elements. For the convenience and clarity of explanation, the thickness or size of each element in the drawings is expressed in an exaggerated, omitted or schematic manner for the understanding and reading of those skilled in the art, and the size of each element is not completely its actual size, and is not used to limit the limiting conditions that the present invention can be implemented, so it has no technical substantive significance. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical content disclosed by the present invention without affecting the effects and purposes that the present invention can produce.
[0037] Please refer to Figure 1 , which is a schematic diagram of the bell circuit C to be tested. Figure 1 As shown, the bell circuit C to be tested includes an input voltage Vin, a bell MC and a bell button B connected in series, wherein the bell button B can be a switch. When the user presses the bell button B, the bell circuit C to be tested is turned on, thereby making the bell MC (e.g., a mechanical doorbell) energized and sounding. In some embodiments, the input voltage Vin is between 16 and 24 volts.
[0038] Please refer to further Figure 2 , which is a schematic diagram of the installation of the smart bell SC in the bell circuit C to be tested, wherein the smart bell SC replaces Figure 1 The illustrated bell button B in the bell circuit C to be tested. The smart bell SC includes a fuse F electrically connected (eg, connected in series) to the bell MC in the bell circuit C to be tested, a switch S, a power circuit W, a processor P, and a load element U.
[0039] When triggered by a user (for example, by pressing a button of the smart bell SC), the switch S is turned on to energize the bell MC on the existing bell circuit C to be tested and make a sound. Different other functions can be provided according to the type of the smart bell SC, for example, a lighting function can be provided when the load element U is a light emitting diode.
[0040] However, since the smart bell SC may be installed by the user himself, and the user may not have sufficient professional knowledge or confirm whether the bell MC can operate normally, at this time, if the bell MC is short-circuited due to damage or other reasons, when the switch S is turned on, the bell circuit C to be tested will be short-circuited and the fuse F will be blown, thereby making the smart bell SC unable to operate.
[0041] In order to solve the above problems, the present disclosure proposes a smart doorbell. Figure 3 , which is a schematic diagram of the smart doorbell 1 in the first embodiment of the present disclosure. Figure 2 The smart bell SC shown in the figure is the same as the smart bell 1. Figure 1 The bell button B in the bell circuit C to be tested is shown. The smart bell 1 includes a power circuit W, a processor P, a read circuit L and a load element U, wherein the processor P is electrically connected to the read circuit L and the load element U to transmit signals and / or measurement data. In some embodiments, the smart bell 1 further includes a fuse F and a switch S connected in series with the bell MC in the bell circuit C to be tested, wherein the fuse F and the switch S are connected in parallel with the read circuit L and the load element U, and the processor P is electrically connected to the switch S to control the switch S to be disconnected or connected. The power circuit W is used to provide power to the processor P, the read circuit L and the load element U. In some embodiments, the power circuit W may include a rectifier.
[0042] In some embodiments, the processor P may include a central processing unit (CPU), a multi-processor, a distributed processing system, an application specific integrated circuit (ASIC), a system on a chip (SoC) and / or a suitable computing unit.
[0043] It should be noted that the processor P is electrically connected to the read circuit L and the load element U. In some embodiments, the processor P further includes an analog-to-digital converter (ADC) for obtaining the voltage on the read circuit L and converting it into a digital signal representing the voltage value, wherein the analog-to-digital converter may be built in the processor P or may be electrically connected between the processor P and the read circuit.
[0044] In some embodiments, the load element U may include an element that provides functions for the smart bell 1. For example, when the load element U includes a light emitting diode, it can provide a lighting function as a light source for a camera of the smart bell 1; or when the load element U includes a heating sheet, it can provide a heating function to ensure that the electronic components inside the smart bell 1 are maintained within an operating temperature range.
[0045] In order to confirm whether the bell MC is correctly installed in the bell circuit C to be tested or whether the bell MC is short-circuited, first, the processor P of the intelligent bell 1 measures the read line L to obtain a first voltage value on the read line L when the load element U is in the off state. Then, the processor P measures the read line L to obtain a second voltage value on the read line L when the load element U is in the on state. Next, the processor P calculates a voltage difference based on the first voltage value and the second voltage value. Finally, in response to the voltage difference being greater than a threshold value, the intelligent bell 1 determines that the bell circuit C to be tested is provided with a bell MC.
[0046] Specifically, when the load element U is turned on and off, the resistance value of the circuit formed by the parallel connection of the reading line L and the load element U will change, and thus the voltage value on the reading line L will also change accordingly. Therefore, the processor P can determine whether the bell MC is short-circuited (i.e., whether there is a resistance of the bell MC on the bell circuit C to be tested) by measuring two different voltage values of the reading line L when the load element U is turned on and off, respectively, and calculating the voltage difference between the two voltage values. It should be noted that, in order to facilitate comparison with the threshold, in some embodiments, the voltage difference is the absolute value of the voltage difference between the two voltage values.
[0047] In some embodiments, the read circuit L and the load element U share the voltage provided by the power supply circuit W, and the resistance value of the read circuit L is much higher than the resistance value of the load element U when it is in operation. Therefore, when the load element U is in the off state (i.e., disconnected), the resistance value of the circuit composed of the read circuit L and the load element U in parallel is equal to the resistance value of the read circuit L; on the other hand, when the load element U is in the on state (i.e., turned on), the resistance value of the circuit composed of the read circuit L and the load element U in parallel will be close to the resistance value of the load element U.
[0048] For example, when the resistance value of the read circuit L is 10,000 ohms and the resistance value of the load element U during operation is 50 ohms, when the load element U is in the off state, the resistance value of the circuit composed of the read circuit L and the load element U in parallel is 10,000 ohms, and when the load element U is in the on state, the resistance value of the circuit composed of the read circuit L and the load element U in parallel will be close to 50 ohms (approximately 49.75 ohms).
[0049] In some embodiments, since the input voltage Vin may vary according to different regions, power grid design and other factors, the processor P cannot directly determine whether there is a resistor of the bell MC on the bell circuit C to be tested by the first voltage value or the second voltage value. Therefore, the processor P calculates the voltage difference between the first voltage value and the second voltage value to reduce the variability caused by the input voltage difference, and further determines whether the bell MC on the bell circuit C to be tested is short-circuited or whether the bell MC is installed on the bell circuit C to be tested according to the voltage difference.
[0050] In this way, through the change in the resistance value of the load element U when it is turned on and off, the processor P can use the measured voltage value difference to determine whether the bell MC on the bell circuit C to be tested is short-circuited or whether the bell MC is installed on the bell circuit C to be tested, and then determine whether the switch S can be turned on without causing damage to the smart bell 1.
[0051] In some embodiments, the read line L includes two resistors connected in series, and the processor P measures the first voltage value and the second voltage value between the two resistors. Figure 4 , which is a schematic diagram of a reading circuit L of an intelligent doorbell 1 composed of a voltage-dividing resistor R1 and a voltage-dividing resistor R2 in the first embodiment of the present disclosure.
[0052] like Figure 4 As shown, the readout circuit L includes a voltage-dividing resistor R1 and a voltage-dividing resistor R2 connected in series, and the processor P electrically connects the readout circuit L between the voltage-dividing resistor R1 and the voltage-dividing resistor R2 to measure the voltage value.
[0053] To explain how the smart bell 1 determines whether the bell MC on the bell circuit C to be tested is short-circuited, please refer to Figure 5 , which is Figure 4 The illustrated equivalent circuit EC1 is a schematic diagram of a bell MC correctly installed in the bell circuit C under test, wherein the bell is correctly installed in the bell circuit C under test.
[0054] Figure 5 The voltage divider resistors R1 and R2 in the illustrated equivalent circuit EC1 correspond to Figure 4 The voltage dividing resistor R1 and the voltage dividing resistor R2 in the reading circuit L are shown; Figure 5 The load equivalent resistance R3 in the illustrated equivalent circuit EC1 corresponds to Figure 4 The load element U shown; Figure 5 The bell equivalent resistor R4 in the illustrated equivalent circuit EC1 corresponds to Figure 4 The illustrated bell MC; and Figure 5 The power line equivalent resistance R5 in the illustrated equivalent circuit EC1 corresponds to Figure 4 The line resistance of the bell circuit C to be tested is shown.
[0055] For example, assume that the resistance values of the voltage-dividing resistor R1 and the voltage-dividing resistor R2 are 10000 ohms respectively, the resistance value of the load element U (i.e., the resistance value of the load equivalent resistor R3) is 50 ohms, the resistance value of the bell MC (i.e., the resistance value of the bell equivalent resistor R4) is 10 ohms, and the line resistance value of the bell circuit C to be tested (i.e., the resistance value of the power line equivalent resistor R5) is 10 ohms.
[0056] Continuing with the above example, when the input voltage Vin is 24 volts and the load element U is in the off state (i.e., the load equivalent resistor R3 is disconnected), the processor P measures the first voltage value obtained between the voltage divider resistor R1 and the voltage divider resistor R2 to be approximately 11.988 volts. Next, when the load element U is in the on state (i.e., the load equivalent resistor R3 is connected), the processor P measures the second voltage value obtained between the voltage divider resistor R1 and the voltage divider resistor R2 to be approximately 8.565 volts. In this way, the processor P can obtain the voltage difference between the first voltage value and the second voltage value, for example, the voltage difference obtained by subtracting the second voltage value from the first voltage value is approximately 3.423 volts, or the processor P can also calculate the absolute value of the voltage difference between the first voltage value and the second voltage value as the voltage difference (also approximately 3.423 volts).
[0057] In another example, when the input voltage Vin is 20 volts and the load element U is in the off state (i.e., the load equivalent resistor R3 is disconnected), the processor P measures the first voltage value obtained between the voltage divider resistor R1 and the voltage divider resistor R2 to be approximately 9.990 volts. Then, when the load element U is in the on state (i.e., the load equivalent resistor R3 is connected), the processor P measures the second voltage value obtained between the voltage divider resistor R1 and the voltage divider resistor R2 to be approximately 7.138 volts. In this way, the processor P can obtain a voltage difference of approximately 2.852 volts by subtracting the second voltage value from the first voltage value, or the processor P can also calculate the absolute value of the voltage difference between the first voltage value and the second voltage value as the voltage difference (also approximately 2.852 volts).
[0058] In another example, when the input voltage Vin is 16 volts and the load element U is in the off state (i.e., the load equivalent resistor R3 is disconnected), the processor P measures a first voltage value between the voltage divider resistor R1 and the voltage divider resistor R2 of approximately 7.992 volts. Then, when the load element U is in the on state (i.e., the load equivalent resistor R3 is connected), the processor P measures a second voltage value between the voltage divider resistor R1 and the voltage divider resistor R2 of approximately 5.710 volts. In this way, the processor P can obtain a voltage difference of approximately 2.282 volts by subtracting the second voltage value from the first voltage value, or the processor P can also calculate the absolute value of the voltage difference between the first voltage value and the second voltage value as the voltage difference (also approximately 2.282 volts).
[0059] However, if Figure 4 The bell MC shown is not installed correctly and short-circuit. Please refer to Figure 6. Figure 4 The equivalent circuit EC2 shown is a schematic diagram of a bell MC in the bell circuit C under test when the bell MC is short-circuited. The difference between the equivalent circuit EC2 and the equivalent circuit EC1 is that the position corresponding to the bell MC in the circuit is in a short-circuit state (ie, there is no bell equivalent resistance R4).
[0060] Assuming that the resistance values of the voltage divider resistor R1, the voltage divider resistor R2, the load equivalent resistor R3 and the power line equivalent resistor R5 in the equivalent circuit EC2 are the same as those in the above example, when the input voltage Vin is 24 volts and the load element U is in the off state (i.e., the load equivalent resistor R3 is disconnected), the processor P measures the first voltage value obtained between the voltage divider resistor R1 and the voltage divider resistor R2 to be approximately 11.994 volts. Then, when the load element U is in the on state (i.e., the load equivalent resistor R3 is connected), the processor P measures the second voltage value obtained between the voltage divider resistor R1 and the voltage divider resistor R2 to be approximately 9.996 volts. In this way, the processor P can obtain a voltage difference of approximately 1.998 volts by subtracting the second voltage value from the first voltage value, or the processor P can also calculate the absolute value of the voltage difference between the first voltage value and the second voltage value as the voltage difference (also approximately 1.998 volts).
[0061] In another example, when the input voltage Vin is 20 volts and the load element U is in the off state (i.e., the load equivalent resistor R3 is disconnected), the processor P measures the first voltage value obtained between the voltage divider resistor R1 and the voltage divider resistor R2 to be approximately 9.995 volts. Then, when the load element U is in the on state (i.e., the load equivalent resistor R3 is connected), the processor P measures the second voltage value obtained between the voltage divider resistor R1 and the voltage divider resistor R2 to be approximately 8.330 volts. In this way, the processor P can obtain a voltage difference of approximately 1.665 volts by subtracting the second voltage value from the first voltage value, or the processor P can also calculate the absolute value of the voltage difference between the first voltage value and the second voltage value as the voltage difference (also approximately 1.665 volts).
[0062] In another example, when the input voltage Vin is 16 volts and the load element U is in the off state (i.e., the load equivalent resistor R3 is disconnected), the processor P measures a first voltage value between the voltage divider resistor R1 and the voltage divider resistor R2 of approximately 7.996 volts. Then, when the load element U is in the on state (i.e., the load equivalent resistor R3 is connected), the processor P measures a second voltage value between the voltage divider resistor R1 and the voltage divider resistor R2 of approximately 6.664 volts. In this way, the processor P can obtain a voltage difference of approximately 1.332 volts by subtracting the second voltage value from the first voltage value, or the processor P can also calculate the absolute value of the voltage difference between the first voltage value and the second voltage value as the voltage difference (also approximately 1.332 volts).
[0063] From the above example, we can see that when the input voltage is between 16 and 24 volts, if Figure 4 If the bell MC shown is correctly installed, the voltage difference calculated by the processor P will be greater than 2.2 volts. Figure 4 The illustrated bell MC is not installed correctly and is short-circuited, and the voltage difference calculated by the processor P will be less than 2 volts.
[0064] In this way, the smart bell 1 can set the threshold value to a voltage value between 2 and 2.2 volts to determine whether the bell MC on the bell circuit C to be tested is short-circuited. It should be noted that, for the convenience of explanation, the resistance values, input voltages and threshold values of the above-mentioned voltage-dividing resistor R1, voltage-dividing resistor R2, load equivalent resistor R3, bell equivalent resistor R4 and power line equivalent resistor R5 are used as examples, but the present disclosure is not limited to the above-mentioned values. In fact, the smart bell 1 can set different threshold values based on different circuit designs, resistance values and input voltage ranges.
[0065] It should be noted that Figure 4 The read circuit L and Figure 5 and Figure 6 The corresponding equivalent circuit diagram shown is only an example for facilitating understanding of the operation of the disclosed technology. However, the read circuit L of the disclosed technology is not limited to the Figures 4 to 6 The illustrated embodiment is limited to this. In fact, the smart doorbell 1 can achieve the technical effect of determining whether the doorbell MC on the doorbell circuit C to be tested is short-circuited based on different reading circuit forms and corresponding operations (for example, calculating voltage differences, setting thresholds, etc.).
[0066] In some embodiments, before the processor P measures the read line L to obtain a first voltage value on the read line L, the processor P turns off the load element U; and before the processor P measures the read line L to obtain a second voltage value, the processor P turns on the load element U.
[0067] Specifically, the processor P can control the operating state of the load element U by transmitting a control signal to the load element U. The processor P can transmit a control signal to the load element U to turn off the load element U before measuring the first voltage value, and transmit a control signal to the load element U to turn on the load element U before measuring the second voltage value. For example, when the load element U is a light emitting diode, the processor P transmits a control signal to the load element U (i.e., the light emitting diode) to stop emitting light before measuring the first voltage value, and transmits a control signal to the load element U (i.e., the light emitting diode) to make the load element U (i.e., the light emitting diode) emit light before measuring the second voltage value.
[0068] In some embodiments, the smart bell 1 is further configured to, in response to determining that a bell MC is provided in the bell circuit C to be tested and the smart bell 1 is triggered, turn on the switch S of the smart bell 1 to trigger the bell MC.
[0069] Specifically, if the smart bell 1 determines that the bell MC on the bell circuit C to be tested is not short-circuited (for example, the voltage difference is greater than the threshold), then when the smart bell 1 is triggered (for example, the user presses a button or the user controls the smart bell 1 through WiFi), the smart bell 1 can turn on the switch S to turn on the bell MC and make a sound.
[0070] On the other hand, the smart bell 1 is further configured to not turn on the switch S in response to determining that the bell circuit C to be tested is not provided with a bell MC and the smart bell 1 is triggered.
[0071] Since the smart bell 1 determines that the bell MC on the bell circuit C to be tested is short-circuited, even if the smart bell 1 is triggered by a button or other means, the smart bell 1 does not turn on the switch S to avoid burning the fuse F or damaging the smart bell 1.
[0072] In some embodiments, the smart doorbell 1 can transmit a control signal to the switch S to control whether the switch S is turned on, for example, the processor P is electrically connected to the switch S to control whether the switch S is turned on. In some embodiments, the switch S can include a wireless transceiver interface to receive a control signal received from the processor P to control whether the switch S is turned on.
[0073] In some embodiments, in response to the voltage difference being less than a threshold, the smart bell 1 transmits a prompt message to the terminal device; and the smart bell 1 determines whether the bell circuit C to be tested is provided with a bell MC based on the confirmation message received from the terminal device.
[0074] Specifically, when the voltage difference is less than the threshold value, the smart bell 1 can transmit a prompt message to the user's terminal device (for example, the smart bell 1 transmits the prompt message to the user's smart phone via Wi-Fi using a transceiver interface). Further, after the terminal device receives the prompt message, the terminal device can prompt the user to manually confirm whether the bell MC is correctly installed on the bell circuit C to be tested or confirm whether the bell MC is short-circuited, and after the user confirms, the smart bell 1 can receive confirmation information from the terminal device to determine whether the bell circuit C to be tested is equipped with a bell MC. In this way, the user can be prompted to confirm the installation status of the bell MC, and at the same time, the user can reconfirm whether the bell MC is correctly installed on the bell circuit C to be tested or confirm whether the bell MC is short-circuited.
[0075] In summary, the smart bell 1 proposed in the present disclosure can measure the voltage value on the reading line L when the load element U is in different operating states, and determine whether the bell MC on the existing bell circuit C to be tested is correctly installed or confirm whether the bell MC is short-circuited according to the voltage value. When the bell MC is short-circuited, the smart bell 1 avoids turning on the switch to avoid damaging the smart bell 1. On the contrary, when the bell MC is correctly installed, the smart bell 1 can turn on the switch when triggered to trigger the bell MC to make a sound. In addition, the smart bell 1 can also prompt the user to confirm the installation status of the bell MC by transmitting a prompt signal to the user's terminal device.
[0076] Please refer to Figure 7 , which is a flow chart of the intelligent doorbell control method 20 in the second embodiment of the present disclosure. Figure 7 As shown, the smart doorbell control method 20 includes steps S21 to S24. The smart doorbell control method 20 is used for a smart doorbell (for example, the smart doorbell 1 in the first embodiment), which is electrically connected to a doorbell circuit to be tested (for example, the doorbell circuit C to be tested in the first embodiment), wherein the smart doorbell includes a read circuit (for example, the read circuit L in the first embodiment) and a load element (for example, the load element U in the first embodiment). However, those skilled in the art in the technical field to which the present disclosure belongs can understand that the smart doorbell control method 20 of the second embodiment of the present disclosure is not limited to the smart doorbell 1 and the doorbell circuit C to be tested of the aforementioned embodiments, nor is it limited to Figure 7 The order of the steps in the flowchart is shown in FIG. 4 , for example, step S22 may be executed before step S21.
[0077] In step S21 , in response to the load element being in an off state, the smart doorbell measures the read circuit to obtain a first voltage value.
[0078] In step S22, in response to the load element being in an on state, the smart doorbell measures the read circuit to obtain a second voltage value.
[0079] In step S23, the smart bell calculates a voltage difference based on the first voltage value and the second voltage value.
[0080] In step S24, in response to the voltage difference being greater than a threshold, the smart bell determines that a bell is provided in the bell circuit to be tested.
[0081] In some embodiments, the read circuit includes two resistors connected in series, and the smart bell measures the first voltage value and the second voltage value between the two resistors.
[0082] In some embodiments, before the smart bell measures the read circuit to obtain the first voltage value, the smart bell turns off the load element; and before the smart bell measures the read circuit to obtain the second voltage value, the smart bell turns on the load element.
[0083] In some embodiments, the smart doorbell further includes a switch electrically connected to the doorbell circuit to be tested, and the smart doorbell control method 20 further includes, in response to determining that the doorbell circuit to be tested is provided with the doorbell and the smart doorbell is triggered, the smart doorbell turns on the switch to trigger the doorbell.
[0084] In some embodiments, the smart doorbell further includes a switch electrically connected to the doorbell circuit to be tested, and the smart doorbell control method 20 further includes, in response to determining that the doorbell circuit to be tested is not provided with the doorbell and the smart doorbell is triggered, the smart doorbell does not turn on the switch.
[0085] In some embodiments, the smart doorbell control method 20 further includes, in response to the voltage difference being less than the threshold, the smart doorbell transmitting a prompt message to the terminal device; and the smart doorbell determining whether the doorbell circuit to be tested is provided with the doorbell based on the confirmation message received from the terminal device.
[0086] In some embodiments, the resistance value of the read line is greater than the resistance value of the load element, and the threshold value is related to the input voltage of the bell circuit.
[0087] In some embodiments, the load element is a light emitting diode or other energy consuming element.
[0088] In summary, the smart bell control method 20 proposed in the present disclosure can measure the voltage value on the read circuit respectively when the load element is in different operating states, and determine whether the bell on the existing bell circuit to be tested is correctly installed or confirm whether the bell is short-circuited according to the voltage value. When the bell is short-circuited, the smart bell control method 20 avoids turning on the switch to avoid damaging the smart bell. On the contrary, when the bell is correctly installed, the smart bell control method 20 can turn on the switch when triggered to trigger the bell to make a sound. In addition, the smart bell control method 20 can also prompt the user to confirm the installation status of the bell by transmitting a prompt signal to the user's terminal device.
