The embodiment of the invention provides an intelligent gateway Internet of things control method applying a block chain technology, which comprises the following steps of 1: acquiring a plurality of first instructions input by a user, wherein the first instructions comprise:
when a user inputs an initial instruction based on an intelligent terminal, three-dimensional scanning is carried out on the current environment of the intelligent terminal to obtain three-dimensional environment information;
constructing a three-dimensional coordinate system according to the three-dimensional environment information based on a preset construction rule;
when the number of first human body outlines in the three-dimensional coordinate system is 1, trying to determine a first identity corresponding to the first human body outline based on a preset outline-identity library;
if the determination is successful, taking the corresponding initial instruction as a first instruction, and acquiring;
when the number of the first human body contours in the three-dimensional coordinate system is larger than 1, determining the first human body contours which are characterized by being held by the intelligent terminal on the basis of a contour recognition technology, and using the first human body contours as second human body contours, and using the rest first human body contours as third human body contours;
attempting to determine a second identity corresponding to the second human body contour based on the contour-identity library;

the position visible condition includes: and the distance between the first position and the second position is less than or equal to a preset distance threshold, and no sight line obstruction exists on a connecting line connecting the first position and the second position in the three-dimensional coordinate system.
The working principle and the beneficial effects of the technical scheme are as follows:
the preset construction rule is specifically as follows: establishing a three-dimensional coordinate system by taking the central position of the intelligent terminal as an origin, extracting the position relation between a position point on each contour (a human body contour and an object contour) and the origin in the three-dimensional environment information, representing each contour in the three-dimensional coordinate system based on the position relation, and completing the construction after the representation is completed; the preset profile-identity library specifically comprises: the database containing the identities corresponding to different profiles allows the user to enter in advance; the preset included angle interval is specifically as follows: for example, [100 °, 170 ° ]; the preset distance threshold specifically comprises: for example, 45 centimeters;
when a user inputs an initial instruction based on an intelligent terminal (such as a tablet computer) and the like, three-dimensional scanning is carried out on the current environment of the intelligent terminal through a millimeter wave radar sensor arranged in the intelligent terminal to obtain three-dimensional environment information; constructing a three-dimensional coordinate system based on the three-dimensional environment information; if only 1 first human body contour exists in the three-dimensional coordinate system, the fact that only one person inputs an initial instruction is shown, whether the contour of the first human body contour corresponds to an identity is verified, if yes, the initial instruction is effective and serves as a second instruction; if the three-dimensional coordinate system has more than 1 first human body contour, which indicates that a plurality of people are present, determining a second human body contour of the handheld intelligent terminal, it is the profile corresponding to the person who inputs the initial instruction, and verifies whether the second human body profile has the corresponding identity, if yes, the initial instruction is valid, if no, the authority of inputting the instruction is not provided, however, whether other authorized persons input instructions to the person corresponding to the second human body outline is checked is determined, if yes, the initial instruction is also effective, therefore, a first orientation of the fourth human body contour face part and a second orientation of the display screen are determined, a first position of the face part and a second position of the display screen are determined, and if the first orientation and the second orientation meet a direction visual condition (namely the face part faces the screen), and the first position and the second position meet a position visual condition (the distance is less than the visual distance, and no shielding exists on the visual line), the initial instruction is effective; for example: parents worry about that the children use the intelligent terminal for misoperation without inputting fingerprints of the children, but the parents can guide the children to use the intelligent terminal for operation on one side, and input instructions are effective;
according to the invention, when the first instruction is obtained, the initial instruction input by a person without authority is removed from the initial instruction as the first instruction, but the special condition that parents accompany children to input the initial instruction is also considered, the input initial instruction is also effective under the condition, the initial instruction can be accurately identified, the method is more humanized, the user experience is improved, and meanwhile, the parents do not need to input the profile information of the children, so that the children are effectively prevented from independently carrying out misoperation.
The embodiment of the invention provides an intelligent gateway Internet of things control method applying a block chain technology, and the method comprises the following steps of: screening out effective second instructions from the first instructions, wherein the effective second instructions comprise:
when the number of the first instructions is 1, taking the first instructions as the second instructions to complete screening;
when the number of the first instructions is larger than 1, analyzing the first instructions to obtain a first instruction type;
inquiring a preset user-instruction type-preference value library, and determining a first preference value corresponding to the user and the first instruction type;
if the first preference value is greater than or equal to a preset preference value threshold, taking the corresponding first instruction as the second instruction to complete one-time screening, and taking the rest first instructions as third instructions;
determining the first instruction type corresponding to the third instruction, and using the first instruction type as a second instruction type;
inquiring a preset instruction type-verification policy library, and determining at least one verification policy corresponding to the second instruction type;
executing the verification policy;
after the execution is finished, when the verification fails, the third instruction corresponding to the second instruction type is removed;
if the first instruction type and the second instruction type pass the verification, taking the corresponding second instruction type as a third instruction type;
determining the first preference value corresponding to the third instruction type, and taking the first preference value as a second preference value;
selecting the third instruction type corresponding to the maximum second preference value as a first target, and taking the rest of the third instruction types as second targets;
randomly combining the first target and the second target to obtain a plurality of instruction type combination pairs;
determining whether the instruction type combination pair conflicts or not based on a preset conflict instruction type combination pair library;
and if so, rejecting the third instruction corresponding to the second target in the instruction combination pair, and taking the third instruction corresponding to the first target and the remaining third instructions corresponding to the second targets as the second instructions after rejection is finished.
The working principle and the beneficial effects of the technical scheme are as follows:
the preset user-instruction type-preference value library specifically comprises: the preference values corresponding to different users and different instruction types are contained, and the greater the preference value is, the more the user tends to the corresponding instruction type; the preset preference threshold specifically includes: for example, 85; the preset instruction type-verification strategy library specifically comprises the following steps: a database containing verification policies corresponding to different instruction types, for example: the command type is that the air conditioner is adjusted to be refrigerated, and the verification strategy is as follows: 1. verifying whether the indoor temperature is proper 2 and verifying whether the outdoor temperature is too high; the preset conflict instruction type combination pair library specifically comprises: contains a large number of combinations of conflicting instruction types, such as: the instruction type A is that the intelligent sound randomly plays light music, the instruction type B is that the intelligent television plays terror, and the instruction type A and the instruction type B conflict;
when the number of the first instructions is only 1, the fact that the user only wants to control the certain Internet of things device independently is shown, and the first instructions are effective and serve as second instructions; when the number of the first instructions is not only 1, acquiring a preference value corresponding to the first instruction type of the first instructions, and when the preference value is greater than a preference value threshold value, indicating that the preference corresponds to the first instructions, corresponding control needs to be performed, and the first instructions belong to effective instructions; the rest third instructions belong to the instructions which are not preferred by the user, and whether the instructions are suitable or not and whether the instructions conflict or not can be verified to perform corresponding elimination; thus, a verification policy corresponding to the second instruction type of the third instruction is determined, for example: the second instruction type is that the sweeper starts sweeping, the verification strategy is to determine whether the time interval between last sweeping and current time of the sweeper is larger than a certain time (the time interval is too short and frequent sweeping is not needed), if yes, the verification is passed, and if not, the corresponding third instruction is directly removed; screening out a first target, wherein the first target is a control type of relative comparison tendency (the second preference value is maximum) of users in the rest instructions, and the rest instruction types are used as second targets; randomly combining the first target and the second target, determining whether the second target conflicts with the first target, if so, rejecting the corresponding second target, and ensuring that the control type of the relative comparative tendency of the user can be executed;
the embodiment of the invention screens the effective second instruction from the first instruction, ensures that the preferred instruction of the user can be executed, is very humanized, eliminates the instruction which does not pass the execution verification strategy, prevents the user from inputting by mistake or inputting according to the actual use condition, is more intelligent, and simultaneously eliminates the conflicting instruction, thereby ensuring that the best experience can be given to the user when the Internet of things equipment is used.
