Description

Technical Field

[0001] The present invention relates to the field of direct current experience technology, and in particular to a direct current experience device and direct current equipment. Background Art

[0002] Direct current, also known as constant current, is a type of direct current. It is direct current with constant magnitude and direction. It means that the voltage and positive and negative poles do not change over time, such as dry batteries; pulsating direct current means that the direction (i.e. positive and negative poles) does not change, but the magnitude changes over time. Direct current is widely used. In fact, all electronic and computer hardware require direct current to work. DC power sources include chemical batteries, fuel cells, thermoelectric batteries, solar cells, DC generators, etc.

[0003] Compared with alternating current, direct current is safer and more efficient. The reason is that direct current has no grounding system. When the human body touches either the positive or negative end, there will be no electric shock. However, when alternating current touches the live wire, it will cause an electric shock accident. Therefore, direct current achieves the inherent safety of electricity.

[0004] Low-voltage DC technology can achieve the inherent safety of electricity use in human living and working environments. In various DC communities, DC working environments, DC showrooms, and DC exhibitions, a device is needed to allow users to experience DC power firsthand to prove the safety of low-voltage DC power use.

[0035] The optional embodiments of the present invention are described in detail below with reference to the accompanying drawings.

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

[0037] The experience circuit 10 is connected to a DC power supply DC, and the working voltage of the experience circuit 10 is adjustable. The experience circuit 10 includes two experience electrodes. When the user touches the two experience electrodes at the same time, the experience circuit 10 forms a loop. The experience electrodes can be metal or non-metal conductive materials.

[0038] The sampling module 20 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 10 forms a loop.

[0039] The interactive module 30 is used to obtain user information and user feedback on the sampled voltage. The interactive module 30 can be a touch display screen with integrated input and output functions, which realizes input through touch operation and output through display. The user can input his own user information and experience feedback through touch operation. Of course, the user can also input his own 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 insensitive.

[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 safety voltage threshold value according to the sampled voltage and the user's feedback.

[0041] The adjustable range of the working voltage of the experience circuit 10 is 36V to 52V. The default standard working voltage of the DC experience device is 48V. It has been verified by experiments 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 feel. The human body current effect threshold is not a fixed value. It is related to many factors such as the human body's own conditions (such as the contact area of ​​the human skin, contact pressure, contact voltage, humidity, temperature, skin type, etc.), the time, frequency, waveform, path of the current flowing through the human body, etc. Therefore, the DC experience device of this embodiment can adjust the working voltage of the experience circuit 10 multiple times in combination with user feedback, so as to test the user's safe voltage threshold.

[0042] The DC experience device of this embodiment enables the user to quickly and conveniently experience the feeling of low-voltage DC current passing through the human body by providing an experience circuit 10, a sampling module 20, an interaction module 30 and a data processing module 40. The user can provide feedback on his or her experience, and the operating voltage of the experience circuit 10 can be adjusted multiple times based on the user feedback, so that the user's safe voltage threshold can be obtained, thereby realizing a concrete display of safe DC power.

[0043] In practical applications, the DC experience device can be made into a suitcase style, the shell is made of insulating material (such as plastic), and the shell can be made as small as possible for easy carrying.

[0044] The experience circuit 10, sampling module 20 and data processing module 40 can be arranged inside the housing. The experience electrodes and interaction module 30 that need to interact with the user can be arranged on the surface of the housing.

[0045] The DC power supply includes: at least one of 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 required DC power supply. The power supply mode selection module can be a physical switch or knob set on the surface of the shell, or a virtual button on the touch screen. This embodiment provides a variety of power supply modes, which can be selected according to actual needs, so that it is convenient to carry and display outside.

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

[0047] For the current sampled voltage, if the user feedbacks that the feeling is strong for a preset number of consecutive times, it is determined that the user's safety voltage threshold is less than the current sampled voltage, and the user is prompted to reduce the working voltage of the experience circuit. After reducing the voltage, the user feedback is continued to be obtained, and the cycle is repeated until the user feedback feels not strong (i.e., no feeling or slight feeling), and the current sampled voltage is determined as the user's safety voltage threshold;

[0048] For the current sampling voltage, if the user feedbacks that he / she feels nothing or feels slightly for a preset number of consecutive times, it is determined that the user's safety voltage threshold is greater than the current sampling voltage, and the user is prompted to increase the working voltage of the experience circuit. After the voltage is increased, user feedback continues to be obtained, and this cycle is repeated until the user feedback feels strongly, and the last sampling voltage is determined as the user's safety voltage threshold.

[0049] The preset number of times can be preset according to actual conditions, for example, 3 times.

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

[0051] A voltage regulating module is connected between the experience circuit 10 and the DC power supply DC, and is used to adjust the working voltage of the experience circuit 10 according to the user's operation. The voltage regulating module may specifically include a boost circuit and a buck circuit to meet the user's needs for reducing or increasing the voltage, thereby determining the user's safe voltage threshold as soon as possible.

[0052] A protection module is connected in series in the experience circuit 10. If the user gives strong feedback for a preset number of consecutive times for any sampled voltage and continues to experience without reducing the working voltage of the experience circuit, the protection module automatically disconnects the power supply of the experience circuit. Alternatively, when the sampled current is greater than a preset threshold, the protection module automatically disconnects the power supply of the experience circuit. The preset threshold is a current limit value pre-set to ensure user safety. The protection module can specifically use an existing protection circuit, which is not limited in this embodiment. The safety of the user experience can be guaranteed by the protection module.

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

[0054] The sampling module 20 includes: a sampling circuit and a sensor. The sampling circuit is connected to 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 10 forms a loop. The sampling circuit can achieve sampling through resistance voltage division. For example, a high-precision sampling circuit is selected to achieve high-precision real-time sampling. The sensor is used to collect environmental information, such as ambient temperature and ambient humidity.

[0055] The interactive module 30 is connected to the sampling module 20 and the data processing module 40, and is used to display the user experience data in real time, wherein the user experience data includes: user information, the sampled voltage, sampled current, human body equivalent resistance and environmental information during the user experience, and the user's safety voltage threshold. The DC experience device has a data display function, which is convenient for users to view the experience in real time and intuitively, so that users can intuitively experience the inherent safety of DC.

[0056] The display mode of the interactive module includes at least one of the following: numerical value, pointer meter and line graph. This embodiment can meet different display requirements through different display modes, which is convenient for users to view intuitively. For example, the sampling voltage, sampling current, human body equivalent resistance, ambient temperature and ambient humidity are displayed in real time through numerical values, and / or the sampling voltage and sampling current are displayed in real time through the pointer voltmeter and microammeter on the surface of the shell, and / or the real-time changes of the sampling voltage, sampling current and human body equivalent resistance are displayed in the form of a line graph.

[0057] The DC experience device may also have a local storage function. Specifically, the DC 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. The data of each experience of the user will be recorded. Based on the local storage function, historical experience data can be viewed. If the same user comes to experience again, when the user enters the user information, the user's previous experience data can be matched from the storage module, so as to directly and automatically obtain the user's safe voltage threshold.

[0058] The DC power experience device may 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, for uploading the user experience data to the server so that the user can view his / her experience data through the user terminal. Uploading the user experience data to the server facilitates the background to store and analyze the data, and gives power safety advice to customers. Users can view their experience data and power safety advice on the supporting webpage and mobile phone APP. The uploaded data can also be used for related power 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 loop. When the user touches the two experience electrodes with both hands at the same time to experience, the experience circuit forms a loop and the light-emitting element emits light, so that the user knows whether the circuit is turned on.

[0060] The DC experience device may further include: a power switch, which may 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 to experience DC power. Based on the power switch, the DC experience device can be turned on and off according to actual needs.

[0061] The direct current experience device is described below in conjunction with a specific embodiment. However, it is worth noting that this specific embodiment is only for better illustrating the present application and does not constitute an improper limitation on the present application. The explanation of terms that are the same or corresponding to the above embodiment will not be repeated in this embodiment.

[0062] LVDC is the abbreviation of Low Voltage Direct Current, which means low voltage direct current.

[0063] refer to Figure 2 , is a schematic diagram of a LVDC48V low-voltage direct current safety experience device. The experience circuit is composed of a protection module 11, a light-emitting element 12 (such as a lamp), and two experience electrodes (such as copper sheets). The experience circuit is connected to a DC power supply DC. After the power is turned on, when the user's hands touch the two experience electrodes at the same time, the experience circuit forms a loop and the light-emitting element 12 is lit.

[0064] A voltage regulating module is connected between the DC power supply DC and the experience circuit to adjust the working voltage of the experience circuit within an adjustable range (i.e. 36V to 52V) according to user operation. Figure 2 The voltage regulating 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 one of the power supply methods. If the built-in power bank or type-c power adapter is used for power supply, the internal voltage induction module allows the built-in power bank or type-c power adapter to output 12V, and then boost it to 48V.

[0066] The sampling and data processing module 13 adopts high-precision real-time sampling, and the accuracy can reach 0.2%. The sampled data include: sampling voltage (i.e., the voltage at both ends of the human body when the experience circuit forms a loop), sampling current (i.e., the current flowing through the human body when the experience circuit forms a loop), ambient temperature, ambient humidity and other data. After the sampling is completed, the sampling voltage / sampling current can be calculated to obtain the equivalent resistance of the human body, and the real-time sampling data and the calculated data are displayed on the display screen 14. The display mode includes mechanical pointer meter display and display screen display. The two display modes are compared to further reflect the authenticity of the data. The data can also be displayed in the form of a line graph on the display screen, which is convenient for real-time observation of data changes.

[0067] The sampling and data processing module 13 can transmit the user experience data to the gateway module 15, and 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, smart energy management system), so that the user can see the real data and data analysis results on the user terminal 17 through the corresponding web page or mobile phone APP.

[0068] Regarding the user's safe voltage threshold, it is determined as follows:

[0069] The user experiences it for the first time, enters user information, and completes registration. At this time, the default operating voltage of the experience circuit is 48V. The user touches the two experience electrodes with both hands at the same time and gives feedback on the current feeling. If the user gives feedback that the feeling is strong for three consecutive times, it is determined that the user's safety voltage threshold is less than 48V. At this time, the user is prompted to lower the operating voltage to determine their own safety voltage threshold. After lowering the voltage, the user touches the two experience electrodes with both hands again at the same time and gives feedback on the current feeling. If the user does not feel strongly at this time, the current sampled voltage can be determined as the user's safety voltage threshold.

[0070] When the working voltage is 48V, if the user reports that he / she feels nothing or feels slightly for three consecutive times, it is determined that the user's safety voltage threshold is greater than 48V. At this time, the user is prompted to increase the working voltage to determine his / her own safety voltage threshold. After increasing the voltage, the user touches the two experience electrodes with both hands again at the same time and reports the current feeling. If the user feels strongly at this time, the last sampled voltage can be determined as the user's safety voltage threshold.

[0071] Therefore, through multiple user experiences and feedback of the experience, the user's safe voltage threshold can be analyzed.

[0072] During the user experience, if the user gives strong feedback for three consecutive times for any sampled voltage and continues to experience without reducing the working voltage, the protection module 11 automatically disconnects the power supply of the experience circuit. If the sampled current is greater than the preset threshold, the protection module 11 will also automatically disconnect the power supply of the experience circuit. The protection module can disconnect the power supply in time to end the experience and ensure user safety. Of course, the user can also actively release the experience electrode and actively end the experience.

[0073] In practical applications, the LVDC48V low-voltage direct current safety experience device can be used in an insulated plastic suitcase with a size of 280mm×240mm×130mm in length, width and height. It is small and beautiful and easy to carry. The panel of the box is equipped with 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 can input experience feedback, leave messages, and view other people's messages. The interactive area can also include various patterns and logos. The box is equipped with a DC power supply, experience circuit, sampling and data processing module, and gateway module.

[0074] Exemplarily, 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 supply is required. If an internal power bank is selected, no external power supply is required. The experiencer touches the two experience electrodes with both hands to experience it. When the human body contacts the voltage and forms a circuit, the light-emitting element on the surface of the box lights up. The pointer 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 uploaded to the server for storage and analysis via wireless transmission. Experiencers can give feedback on their experience and leave messages in the interactive area, and can also view other users' messages and replies on the user terminal.

[0075] like Figure 3 As shown, it is a schematic diagram of the process of direct current experience, including the following steps:

[0076] S301, start the experience.

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

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

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

[0080] S305, calculating the human body equivalent resistance according to the sampled voltage and the sampled current.

[0081] S306, obtaining user feedback, and checking whether the user feedback is positive. If so, proceed to S307, otherwise proceed to S308.

[0082] S307, reducing the voltage, combining user feedback, and determining the user's safe voltage threshold after multiple experiences.

[0083] S308, increase the voltage, and determine the user's safe voltage threshold after multiple experiences based on user feedback.

[0084] S309, end the experience.

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