Description

Technical Field

[0001] This utility model relates to the field of DC experience technology, and more specifically, to a DC power experience device and DC power equipment. Background Technology

[0002] Direct current (DC), also known as constant current, is a type of DC where both its magnitude and direction remain constant. This means that the voltage and polarity do not change over time, as seen in dry cell batteries. Pulsating DC, on the other hand, has a constant direction (positive and negative terminals) but its magnitude varies over time. DC has a very wide range of applications; in fact, all electronic and computer hardware requires DC to operate. DC power sources include chemical batteries, fuel cells, thermoelectric cells, solar cells, and DC generators.

[0003] Compared to alternating current (AC), direct current (DC) is safer and more efficient because DC is an ungrounded system. When a person touches either the positive or negative end, they will not get an electric shock. In contrast, contact with a live wire in AC can lead to an electric shock. Therefore, DC achieves inherent electrical safety.

[0004] Low-voltage DC technology can ensure the inherent safety of electricity use in residential and working environments. In various DC communities, DC work environments, DC exhibition halls, and DC exhibitions, there is a need for a device to allow users to personally experience DC power in order to prove the safety of low-voltage DC electricity use.

[0007] The experience circuit is connected to a DC power supply, and the operating voltage of the experience circuit is adjustable. The experience circuit includes two experience electrodes, and when the user touches the two experience electrodes simultaneously, the experience circuit forms a loop.

[0008] The sampling module is connected to the two experience electrodes and is used to collect the voltage across the human body and the current flowing through the human body when the experience circuit forms a circuit.

[0012] Optionally, the data processing module is specifically used for:

[0013] If the user feels a strong sensation after a preset number of consecutive sampling voltages, it is determined that the user's safe voltage threshold is less than the current sampling voltage. The user is then prompted to reduce the operating voltage of the experience circuit. After the voltage is reduced, user feedback is collected again. This process is repeated until the user's feedback is no longer strong, at which point the current sampling voltage is determined as the user's safe voltage threshold.

[0014] If, for the current sampling voltage, the user reports no sensation or only slight sensation after a preset number of consecutive tests, it is determined that the user's safe voltage threshold is greater than the current sampling voltage. The user is then prompted to increase the operating voltage of the experience circuit. After increasing the voltage, user feedback is collected again, and this process is repeated until the user reports a strong sensation. At this point, the previous sampling voltage is determined as the user's safe voltage threshold.

[0019] Optionally, the interactive module may display data in at least one of the following ways: numerical values, pointer tables, and line graphs.

[0020] Optionally, the DC power experience device further includes:

[0021] A storage module, connected to the sampling module, the interaction module, and the data processing module, is used to store user experience data.

[0035] The optional embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0036] To allow users to experience low-voltage direct current, this invention provides a direct current experience device. Figure 1 This is a schematic diagram of the DC power experience device provided in an embodiment of the present invention, as shown below. Figure 1 As shown, the DC power experience device includes: experience circuit 10, sampling module 20, interaction module 30 and data processing module 40.

[0037] The experience circuit 10 is connected to a DC power supply, and its operating voltage is adjustable. The experience circuit 10 includes two experience electrodes; when a user touches both electrodes simultaneously, the experience circuit 10 forms a circuit. The experience electrodes can be made of conductive materials, either metallic or non-metallic.

[0038] The sampling module 20 is connected to two experience electrodes to collect the voltage across the human body and the current flowing through the human body when the experience circuit 10 forms a circuit.

[0039] The interaction module 30 is used to acquire user information and obtain user feedback on the sampled voltage. The interaction module 30 can be a touchscreen display with integrated input / output functions. Input is achieved through touch operation, and output is achieved through display. Users can input their user information and experience feedback through touch operation. Alternatively, users can input their user information and experience feedback through a voice input module or a physical keyboard. User information includes: nickname, body temperature, height, weight, gender, age, etc. The sampled voltage is the voltage actually experienced by the user, and the user's feedback on the sampled voltage can be strong, slight, or imperceptible.

[0040] The data processing module 40 is connected to the sampling module 20 and the interaction module 30, and is used to determine the user's safe voltage threshold based on the sampled voltage and user feedback.

[0041] The adjustable operating voltage range of the experience circuit 10 is 36V to 52V. The default standard operating voltage of the DC current experience device is 48V, and experiments have verified that 48V DC voltage is safe for the human body. The human body current effect threshold is the minimum current value that the human body can perceive. The human body current effect threshold is not a fixed value; it is related to many factors such as the individual's condition (e.g., the contact area of ​​the skin, contact pressure, contact voltage, humidity, temperature, skin type, etc.), the time, frequency, waveform, and path of the current flowing through the body. Therefore, the DC current experience device in this embodiment can adjust the operating voltage of the experience circuit 10 multiple times based on user feedback, thereby testing the user's safe voltage threshold.

[0042] The DC current experience device in this embodiment, by setting up an experience circuit 10, a sampling module 20, an interaction module 30, and a data processing module 40, enables users to conveniently and quickly experience the feeling of low-voltage DC current passing through the human body. Users can provide feedback on their experience, and the operating voltage of the experience circuit 10 can be adjusted multiple times based on user feedback, thereby obtaining the user's safe voltage threshold and realizing a concrete demonstration of safe DC current.

[0043] In practical applications, DC power experience devices can be made in the style of a suitcase, with the casing made of insulating materials (such as plastic), and the casing can be made as small as possible for easy carrying.

[0044] The aforementioned experience circuit 10, sampling module 20, and data processing module 40 can be housed inside the housing. The experience electrodes and interaction module 30, which require user interaction, can be housed on the surface of the housing.

[0045] The DC power supply includes at least one of the following: an external 48V DC power supply, a built-in battery, and a power adapter. The DC power experience device also includes a power supply mode selection module for selecting the desired DC power supply. The power supply mode selection module can be a physical switch or knob located on the surface of the housing, or it can be a virtual button on a touchscreen. This embodiment provides multiple power supply methods, which can be selected according to actual needs, facilitating portability and demonstration.

[0046] The data processing module 40 is specifically used for:

[0047] If the user reports a strong feeling for the current sampling voltage after a preset number of consecutive tests, it is determined that the user's safe voltage threshold is less than the current sampling voltage. The user is then prompted to reduce the operating voltage of the experience circuit. After the voltage is reduced, the user feedback is collected again. This process is repeated until the user's feedback is not strong (i.e., no feeling or slight feeling). At this point, the current sampling voltage is determined as the user's safe voltage threshold.

[0048] If the user reports no sensation or only slight sensation after a preset number of consecutive sampling voltages, it is determined that the user's safe voltage threshold is greater than the current sampling voltage. The user is then prompted to increase the operating voltage of the experience circuit. After increasing the voltage, the user feedback is collected again, and this process is repeated until the user reports a strong sensation. At this point, the previous sampling voltage is used as the user's safe voltage threshold.

[0049] The preset number of times can be set in advance according to the actual situation, such as 3 times.

[0050] This embodiment can quickly determine the user's safe voltage threshold based on user feedback and voltage adjustment operations.

[0051] A voltage regulation module is connected between the experience circuit 10 and the DC power supply to adjust the operating voltage of the experience circuit 10 according to user operation. The voltage regulation module may specifically include a boost circuit and a buck circuit to meet the user's needs to adjust the voltage to a smaller or larger value, thereby quickly determining the user's safe voltage threshold.

[0052] A protection module is connected in series in the experience circuit 10. If, for any given sampling voltage, the user experiences a strong feedback sensation for a preset number of consecutive cycles and continues to experience the circuit without reducing its operating voltage, the protection module automatically disconnects the power supply to the experience circuit. Alternatively, the protection module automatically disconnects the power supply to the experience circuit when the sampling current exceeds a preset threshold. The preset threshold is a pre-set current limit to ensure user safety. Existing protection circuits can be used for the protection module; this embodiment does not impose any limitations on this. The protection module ensures the safety of the user experience.

[0053] The data processing module 40 can also be used to calculate the equivalent resistance of the human body based on the sampled voltage and sampled current. Specifically, the sampled voltage / sampled current is calculated to obtain the equivalent resistance of the human body.

[0054] The sampling module 20 includes a sampling circuit and a sensor. The sampling circuit is connected to two sensing electrodes and is used to collect the voltage across the human body and the current flowing through the human body when the sensing circuit 10 forms a circuit. The sampling circuit can achieve sampling through resistive voltage division; for example, a high-precision sampling circuit can be selected to achieve high-precision real-time sampling. The sensor is used to collect environmental information, such as ambient temperature and humidity.

[0055] The interaction module 30 is connected to the sampling module 20 and the data processing module 40, and is used to display user experience data in real time. This user experience data includes: user information, the sampling voltage, sampling current, human body equivalent resistance, and environmental information during the user experience, as well as the user's safe voltage threshold. The DC power experience device has a data display function, allowing users to easily and intuitively view their experience in real time, enabling them to directly experience the inherent safety of DC power.

[0056] The interactive module can display data in at least one of the following ways: numerical values, pointer meters, and line graphs. This embodiment can meet different display needs through different display methods, facilitating intuitive viewing for users. For example, it can display the sampling voltage, sampling current, human body equivalent resistance, ambient temperature, and ambient humidity in real time using numerical values; and / or, it can display the sampling voltage and sampling current in real time using pointer-type voltmeters or microammeters on the surface of the casing; and / or, it can display the real-time changes in sampling voltage, sampling current, and human body equivalent resistance using line graphs.

[0057] The DC power experience device can also have local storage functionality. Specifically, the DC power experience device may include a storage module connected to the sampling module 20, the interaction module 30, and the data processing module 40, for storing user experience data. Each user experience records the data for that experience. Based on the local storage function, historical experience data can be viewed. If the same user experiences the device again, when the user enters user information, the storage module can be used to retrieve the user's previous experience data, thereby automatically obtaining the user's safe voltage threshold.

[0058] The DC power experience device can also have a data upload function. Specifically, the DC power experience device may include a gateway module connected to the sampling module 20, the interaction module 30, and the data processing module 40, used to upload user experience data to the server so that users can view their experience data through their user terminals. Uploading user experience data to the server facilitates data storage and analysis in the background, providing customers with electricity safety advice. Users can view their experience data and electricity safety advice on the accompanying webpage and mobile APP. The uploaded data can also be used for relevant electricity safety research.

[0059] A light-emitting element is connected in series in the experience circuit 10. The light-emitting element can be located on the surface of the housing and is used to emit light when the experience circuit forms a circuit. When the user touches two experience electrodes simultaneously with both hands to experience the circuit, the experience circuit forms a circuit, and the light-emitting element emits light so that the user can know whether the circuit is conducting.

[0060] The DC power experience device may also include a power switch, which can be located on the surface of the housing. When the power switch is turned on, the experience circuit is powered on, and the user can begin experiencing DC power. The power switch allows for control of the DC power experience device's on / off state according to actual needs.

[0061] The DC power experience device described above will now be described with reference to a specific embodiment. However, it is worth noting that this specific embodiment is only for better illustration of this application and does not constitute an undue limitation of this application. The same or corresponding terminology used in the above embodiment will not be repeated in this embodiment.

[0062] LVDC is an abbreviation for Low Voltage Direct Current, which means low-voltage direct current.

[0063] refer to Figure 2 This is a schematic diagram of an LVDC 48V low-voltage direct current safety experience device. The experience circuit consists of a protection module 11, a light-emitting element 12 (e.g., a lamp), and two experience electrodes (e.g., copper sheets). The experience circuit is connected to a DC power supply. When the power is turned on, and the user touches both experience electrodes simultaneously, the experience circuit forms a loop, and the light-emitting element 12 is lit.

[0064] A voltage regulator module is connected between the DC power supply and the experience circuit to adjust the operating voltage of the experience circuit within an adjustable range (36V to 52V) according to user operation. Figure 2 The voltage regulation module is not shown.

[0065] The DC power supply can be powered by an external 48V DC power supply, a built-in power bank, or a Type-C power adapter; users can choose any power supply method. If a built-in power bank or Type-C power adapter is selected, the internal voltage induction module allows the built-in power bank or Type-C power adapter to output 12V, which is then boosted to 48V.

[0066] The sampling and data processing module 13 employs high-precision real-time sampling, achieving an accuracy of 0.2%. The sampled data includes: sampling voltage (the voltage across the human body when the circuit forms a loop), sampling current (the current flowing through the human body when the circuit forms a loop), ambient temperature, and ambient humidity. After sampling, the sampling voltage / current ratio is calculated to obtain the equivalent resistance of the human body. The real-time sampling data and the calculated data are displayed on the screen 14. Display methods include mechanical pointer meter display and screen display; comparing the two methods enhances the data's accuracy. The data can also be displayed on the screen as a line graph for easy real-time observation of data changes.

[0067] The sampling and data processing module 13 can transmit user experience data to the gateway module 15. The gateway module 15 can directly upload the user experience data to the server 16 (specifically, it can be an IEMS server, Intelligent Energy Management System). As a result, users can see the real data and data analysis results on the user terminal 17 through the accompanying webpage or mobile APP.

[0068] The method for determining the user's safe voltage threshold is as follows:

[0069] For the first user experience, after entering user information and completing registration, the default operating voltage of the experience circuit is 48V. The user touches both experience electrodes simultaneously with both hands and provides feedback on their current sensations. If the user reports a strong sensation three times consecutively, it is determined that the user's safe voltage threshold is less than 48V. At this point, the user is prompted to reduce the operating voltage to determine their own safe voltage threshold. After reducing the voltage, the user touches both experience electrodes simultaneously with both hands again and provides feedback on their current sensations. If the user's sensations are not strong this time, the current sampling voltage can be determined as the user's safe voltage threshold.

[0070] If, under a working voltage of 48V, the user reports no sensation or only slight sensation three times in a row, it is determined that the user's safe voltage threshold is greater than 48V. At this time, the user is prompted to increase the working voltage to determine their own safe voltage threshold. After increasing the voltage, the user touches both experience electrodes with both hands again and reports the current sensation. If the user feels a strong sensation at this time, the previous sampling voltage can be determined as the user's safe voltage threshold.

[0071] Therefore, by having users experience the product multiple times and provide feedback, it is possible to analyze the user's safe voltage threshold.

[0072] During the user experience, if the user experiences a strong sensation three consecutive times for any given sampling voltage and continues the experience without reducing the operating voltage, the protection module 11 will automatically disconnect the power supply to the experience circuit. The protection module 11 will also automatically disconnect the power supply to the experience circuit if the sampling current exceeds a preset threshold. This timely power disconnection ensures user safety and terminates the experience. Alternatively, the user can manually release the experience electrodes to end the experience.

[0073] In practical applications, the LVDC 48V low-voltage DC safety experience device can be housed in an insulated plastic carrying case, measuring 280mm × 240mm × 130mm, making it compact, aesthetically pleasing, and easy to carry. The case panel features a power switch, experience electrodes, light-emitting elements, and a display screen. The display screen includes a display area and an interactive area. The interactive area allows users to input feedback, leave messages, and view others' messages, and can also display various patterns and logos. The case contains a DC power supply, experience circuitry, sampling and data processing modules, and a gateway module.

[0074] For example, the user turns on the power switch on the surface of the experience box and selects the power supply. If an external 48V DC power supply is selected, an external 48V power source is required; if an internal power bank is selected, no external power source is needed. The user experiences the experience by touching two experience electrodes with both hands. When the human body comes into contact with voltage and forms a circuit, the light-emitting element on the surface of the box lights up. The pointer-type voltmeter, microammeter, and display screen on the surface of the box can display the voltage, current, and equivalent resistance of the human body in real time. At the same time, the user experience data can be wirelessly transmitted to the server for storage and analysis. Users can provide feedback and leave messages in the interactive area, and can also view other users' messages and replies on the user terminal.

[0075] like Figure 3 The diagram shown illustrates the process of experiencing direct current (DC) electricity, including the following steps:

[0076] S301, starting the experience.

[0077] S302, Obtain environmental information, such as ambient temperature and ambient humidity.

[0078] S303 retrieves user information such as nickname, age, gender, body temperature, weight, and height.

[0079] S304 When the user touches both experience electrodes with both hands at the same time, the experience circuit forms a loop to obtain the real-time sampling voltage and sampling current.

[0080] S305 calculates the equivalent resistance of the human body based on the sampling voltage and sampling current.

[0081] S306, Obtain user feedback. Is the user feedback noticeable? If yes, proceed to S307; otherwise, proceed to S308.

[0082] S307, by adjusting the voltage and combining user feedback, the user's safe voltage threshold can be determined after multiple tests.

[0083] S308, by increasing the voltage and combining user feedback, the user's safe voltage threshold can be determined after multiple tests.

[0084] S309, end of experience.

[0085] The execution order of steps S302 and S303 can be changed, or they can be executed simultaneously.
