[0096] Preferably, the communication connection method includes electrical connection, Bluetooth connection, wireless local area network connection, etc. This specification does not limit the connection method of the communication connection.

[0097] According to the above embodiment, the child height measuring device includes a bracket 2, a target distance acquisition component 3, a controller 1 and a plurality of pressure acquisition sensors 4. Among them, the bracket 2 includes a base 21 and a bracket body 22 connected in sequence. The target distance acquisition component 3 includes a first slide rail 31, a first pulley 32, a second slide rail 33, a second pulley 34, a contact member 35, and a distance sensor 36 connected in sequence. The first slide rail 31 is connected to the bracket body 22, and the first pulley 32 and the distance sensor 36 are both connected to the controller 1 for communication. The first pulley 32 has a built-in motor, which can slide up and down in the vertical direction under the drive of the motor in response to the instruction of the controller 1. The distance sensor 36 is used to collect target height information and send the target height information to the controller 1.

[0105] Preferably, the controller 1 is used to receive target height information, relative height information and pressure information at multiple measurement moments. Wherein, each measurement moment corresponds to multiple pressure information. The controller 1 is also used to, based on the values ​​of the multiple pressure information at the multiple measurement moments, in the multiple pressure information corresponding to the two adjacent measurement moments, in chronological order, reduce the value of the pressure information by at least a preset tiptoe parameter, and determine it as the first changed pressure information. The controller 1 is also used to determine the measurement moment corresponding to the first changed pressure information as the error moment. The controller 1 is also used to determine the height data of the child being measured based on the target height information and relative height information corresponding to the measurement moments other than the error moment.

[0106] The above is a method for measuring the height of a child provided in one or more embodiments of this specification. Based on the same idea, this specification also provides a corresponding device for measuring the height of a child.

[0107] Figure 8 A schematic diagram of a method for measuring the height of a child provided in one embodiment of this specification, such as Figure 8 As shown, the method specifically comprises the following steps:

[0108] S800: Acquire target height information, relative height information, and pressure information at multiple measurement moments; wherein each measurement moment corresponds to multiple pieces of pressure information.

[0109] In one or more embodiments of this specification, the child height measurement method can be executed by an electronic device, and the electronic device can specifically be a child height measurement device, a single chip microcomputer, a controller in the child height measurement device provided in the above embodiments, etc. The electronic device is not limited in this specification. In this specification, the method is described by taking a controller executing the method as an example.

[0110] When measuring the height of a child, the child may stand on tiptoe or other irregular postures for the purpose of playing or vanity, thereby obtaining a higher height data. Obviously, such irregular standing postures as standing on tiptoe will affect the height measurement results, so in one or more embodiments of the present specification, the following method may be used to measure the height of a child.

[0111] Preferably, the controller can obtain target height information, relative height information and pressure information at multiple measurement moments.

[0112] The target height data and the relative height information represent the height measurement result of the measured child, and the pressure information represents the force sensed by the pressure sensor provided on the child height measurement device when the measured child stands on the child height measurement device.

[0113] Usually, the measured child will stand on both feet to measure the height, so in one or more preferred embodiments of this specification, there are at least two pieces of pressure information. More preferably, there are multiple pieces of pressure information.

[0114] Preferably, there are multiple measurement moments, that is, there are multiple pressure information, target height information, and relative height information corresponding to the measurement moments, so as to ensure that after the target height information and relative height information collected when the measured child stands on tiptoe are deleted, the height data of the measured child can also be determined based on the target height information and relative height information collected at other measurement moments.

[0115] Preferably, the multiple measurement moments may be continuous or dispersed.

[0116] Preferably, the maximum time interval between the multiple measurement moments is at least greater than 10 s or 15 s or 30 s or 1 min.

[0117] S802: According to the values ​​of the multiple pressure information at the multiple measurement moments, among the multiple pressure information corresponding to two adjacent measurement moments, in chronological order, the pressure information whose value is reduced by at least a preset tiptoe parameter is determined as the first changed pressure information.

[0118] In order to eliminate the target height information and relative height information collected when the measured child stands on tiptoe, the controller can analyze the pressure information collected at the multiple measurement moments.

[0119] Specifically, the controller can determine the pressure information with a value reduced by at least a preset tiptoeing parameter in the multiple pressure information corresponding to two adjacent measurement moments in chronological order based on the values ​​of the multiple pressure information at the multiple measurement moments as the first changed pressure information.

[0120] For example, at 12:01:01, the pressure information is 20, 0, 18, 0, 19. At 12:01:04, which is adjacent to the above time, the pressure information is 0, 0, 38, 0, 19. Then, in chronological order, compared with 12:01:01, the first pressure information at 12:01:04 is reduced by 20, and 20 is greater than the preset tiptoe parameter of 15, so the controller can determine that the pressure information of 0, 0, 38, 0, 19 is all the first change pressure information.

[0121] By adopting the above method, the pressure information in which the pressure suddenly decreases and the decrease amplitude is too large is determined as the first change pressure information, which reduces the error and accurately finds the moment when the measured child tiptoes and moves.

[0122] S104: Determine the measurement time corresponding to the first change pressure information as the error time.

[0123] Preferably, after determining the moment when the measured child stands on tiptoe or moves, the controller can determine the corresponding moment as the error moment. Specifically, the controller can determine the measurement moment corresponding to the first change pressure information as the error moment.

[0124] S106: Determine the height data of the measured child according to the target height information and relative height information corresponding to the measurement time except the error time.

[0125] After excluding the moments when the child being tested stands on tiptoe, moves, etc., the controller can eliminate the data collected at the corresponding moments.

[0126] Specifically, firstly, the controller may eliminate the target height information and relative height information collected at the error time from the multiple target height information and relative height information.

[0127] Secondly, the controller may determine at least one to-be-selected height data based on the remaining at least one set of target height information and relative height information.

[0128] Secondly, the controller may determine the average value of the height data to be selected as the height data of the child to be measured. Alternatively, the controller may determine the median, maximum value, minimum value or mode of the height data to be selected as the height data of the child to be measured. This specification does not limit the method of determining the height data of the child to be measured based on the height data to be selected.

[0129] based on Figure 1 In the child height measurement method shown, the controller can obtain target height information, relative height information and pressure information at multiple measurement moments. Then, according to the values ​​of the multiple pressure information at the multiple measurement moments, in the multiple pressure information corresponding to the two adjacent measurement moments, in chronological order, the pressure information whose value is at least reduced by the preset tiptoe parameter is determined as the first change pressure information. Then, the measurement moment corresponding to the first change pressure information is determined as the error moment. Finally, according to the target height information and relative height information corresponding to the measurement moments other than the error moment, the height data of the measured child is determined.

[0130] It can be seen from the above method that the controller determines and eliminates the target height information and relative height information collected when the measured child is standing on tiptoe or moving based on multiple pressure information collected at multiple measurement moments, thereby improving the accuracy of height measurement.

[0131] Those skilled in the art will appreciate that, generally, a child height measurement device needs to respond to a user's operation before it can measure height. Therefore, in one or more preferred embodiments provided in this specification, when the controller acquires pressure information at multiple measurement moments in step S100, the pressure information may be acquired in the following manner.

[0132] First, the controller can continuously obtain pressure information at multiple measurement moments. Secondly, the controller can determine, based on the values ​​of the pressure information at the multiple measurement moments, whether there are multiple pressure information corresponding to at least one measurement moment, and n pressure information values ​​are greater than the preset child presence parameter. If so, continue to execute subsequent steps. If not, re-acquire the pressure information at multiple measurement moments, and return the values ​​of the pressure information based on the multiple measurement moments to determine whether there are multiple pressure information corresponding to at least one measurement moment, and n pressure information values ​​are greater than the preset child presence parameter. Until the judgment structure is yes. Among them, n is a preset value, which can be 1, 2, 3, etc. The child presence parameter is also a preset value, which can be 10, 15, 20, etc.

[0133] That is to say, when there is no child being measured whose height is being measured, the controller can judge the size of the multiple pressure information it has collected. When it is determined that there are n pressure sensors that have collected data with a value greater than the child's presence parameter at the same time, it indicates that there is a child measuring his height. At this time, the child height collection device can execute the subsequent steps. If the child height collection device does not have n data with a value greater than the child's presence parameter, it indicates that there is no child being measured whose height is being measured, and the electronic device needs to re-collect until there is a child being measured whose height is being measured, and the electronic device can continue to execute steps S100-S106.

[0134] Preferably, the child height collection device can also directly start executing steps S100-S106 in response to the operation of the measured child.

[0135] Those skilled in the art will appreciate that the child being measured may stand on tiptoe to get on the child height collection device. Therefore, in one or more preferred embodiments of the specification, the child height collection device may measure the user who stands on tiptoe to get on the child height collection device in the following manner before executing step S106.

[0136] Specifically, first, the body data collection device for the child being tested can, based on the values ​​of the multiple pressure information at the multiple measurement moments, reduce the pressure information with a value of at least a preset landing parameter among the multiple pressure information corresponding to the two adjacent measurement moments in chronological order from back to front, and determine it as the second changed pressure information.

[0137] Secondly, the measured child's body data collection device can determine the measurement time corresponding to the second change pressure information as the error time.

[0138] For example, at 12:01:01, the pressure information is 0, 0, 40, 41, 39. At 12:01:04, which is adjacent to the above time, the pressure information is 16, 26, 18, 21, 19. Then, in chronological order, compared with 12:01:04, the second pressure information at 12:01:01 is reduced by 26, and 26 is greater than the preset landing parameter of 18, so the controller can determine that the pressure information 0, 0, 40, 41, 39 are all the second change pressure information.

[0139] By adopting the above method, the controller avoids the error caused by the measured child standing on tiptoe to climb onto the device, thereby improving the accuracy of measurement.

[0140] Preferably, the controller can play and / or display a preset prompt message during, before, or after any step to prompt the child to stand in the pressure information collection area. Of course, the prompt message can also prompt other content, which is not limited in this specification.

[0141] Preferably, before executing step S100, the controller may also obtain at least one piece of pressure information within a preset height measurement interval, and send an information collection instruction to instruct the first trolley to slide along the first slide rail.

[0142] It should be noted that all actions of acquiring signals, information or data in this application are carried out in compliance with the relevant data protection laws and policies of the country where they are located, and with the authorization given by the owner of the corresponding device.

[0143] The above are the child height measurement methods and child height measurement equipment provided by one or more embodiments of this specification. Based on the same idea, this specification also provides a corresponding child height measurement device.

[0144] Fig. 9 This is a schematic diagram of a device for measuring the height of children provided in this manual. Fig. 9 As shown, the device specifically includes:

[0145] The acquisition unit 900 is used to acquire target height information and pressure information at multiple measurement moments; wherein each measurement moment corresponds to multiple pressure information;

[0146] The calculation unit 902 is used to determine, according to the values ​​of the multiple pressure information at the multiple measurement moments, the pressure information whose value is at least reduced by a preset tiptoe parameter among the multiple pressure information corresponding to two adjacent measurement moments in chronological order as the first changed pressure information; wherein any one of the first changed pressure information may correspond to multiple groups of adjacent measurement moments;

[0147] A screening unit 904 is used to determine, for each first pressure change information, a later measurement time in each group of adjacent measurement times corresponding to the first pressure change information as an error time;

[0148] The determination unit 906 is used to determine the height data of the measured child according to the target height information corresponding to the measurement time except the error time.

[0149] This specification also provides a computer-readable storage medium, which stores a computer program, which can be used to execute the above Figure 8 Provided methods for measuring children's height.

[0150] This specification also provides a computer program product. When the instructions in the computer program product are executed by the processor of the child height measurement device, the child height measurement device can achieve the above Figure 8 Provided methods for measuring children's height.

[0151] In addition, in one or more preferred embodiments provided in this specification, the above Figure 1 The controller in the corresponding child height measuring device may also store a computer program product, and when the controller runs the computer program product, it may only perform the above Figure 8 Provided methods for measuring children's height.

[0152] In the 1990s, it was very clear whether the improvement of a technology was a hardware improvement (for example, improvements to the circuit structure of diodes, transistors, switches, etc.) or a software improvement (improvement of the method flow). However, with the development of technology, many improvements in the method flow today can be regarded as direct improvements in the hardware circuit structure. Designers almost always obtain the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that the improvement of a method flow cannot be implemented using a hardware entity module. For example, a programmable logic device (PLD) (such as a field programmable gate array (FPGA)) is such an integrated circuit whose logical function is determined by the user's programming of the device. Designers can "integrate" a digital system on a PLD by programming it themselves, without having to ask a chip manufacturer to design and produce a dedicated integrated circuit chip. Moreover, nowadays, instead of manually making integrated circuit chips, this kind of programming is mostly implemented by "logic compiler" software, which is similar to the software compiler used when developing and writing programs, and the original code before compilation must also be written in a specific programming language, which is called hardware description language (HDL). There is not only one HDL, but many kinds, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc. The most commonly used ones are VHDL (Very-High-Speed ​​Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art should also know that it is only necessary to program the method flow slightly in the above-mentioned hardware description languages ​​and program it into the integrated circuit, and then it is easy to obtain the hardware circuit that implements the logic method flow.

[0153] The controller can be implemented in any appropriate manner, for example, the controller can take the form of a microprocessor or processor and a computer-readable medium storing a computer-readable program code (such as software or firmware) that can be executed by the (micro)processor, a logic gate, a switch, an application-specific integrated circuit (ASIC), a programmable logic controller, and an embedded microcontroller. Examples of controllers include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320. The memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art also know that in addition to implementing the controller in a purely computer-readable program code manner, the controller can be implemented in the form of a logic gate, a switch, an application-specific integrated circuit, a programmable logic controller, and an embedded microcontroller by logically programming the method steps. Therefore, this controller can be considered as a hardware component, and the devices included therein for implementing various functions can also be regarded as structures within the hardware component. Or even, the devices for implementing various functions can be regarded as both software modules for implementing the method and structures within the hardware component.
