Description

Technical Field

[0001] The invention belongs to the technical field of dot matrix positioning, and in particular relates to a high-precision dot matrix positioning method without a base station. Background Art

[0002] In current life, in special operations or combat environments where there is no support from environmental technical facilities, such as in underground bunkers, underground garages, unknown buildings, and canyon forests, it is impossible to set up fixed positioning base stations. Even in special operations or combat scenarios, temporary installation of fixed positioning base stations is not allowed. All communication and positioning units must move with the highly dynamic operation or combat unit personnel. In this scenario, the instantaneous dynamic dot matrix positioning system between the operation or combat unit personnel is crucial to the efficient coordination between personnel and the safety of personnel. Therefore, it is particularly important to develop a high-precision dot matrix positioning method without a base station. Summary of the invention

[0003] The purpose of the present invention is to provide a high-precision dot matrix positioning method without a base station in order to solve the above problems, thereby solving the problems mentioned in the background technology.

[0004] The present invention provides a base station-free high-precision dot matrix positioning method, comprising the following steps:

[0005] S1. Creation of transient dot matrix positioning: First, select the transient reference coordinate system, create the target group dot matrix positioning data system, and eliminate false targets.

[0006] S2. Transient dot matrix positioning state migration: Then determine multiple positioning measurement cycles, and establish a dot matrix positioning relationship diagram. Then, use the passage of time to observe the changes in the coordinate system, and at the same time establish a dot matrix positioning transient database to create a cycle P.

[0007] S3. Adopt in-band communication mechanism: In addition to the fixed processing delay of the processing chip, it provides a sub-millisecond dot matrix positioning attitude database creation cycle and provides basic support for system capacity.

[0008] S4. Flexibly modulate the target dot matrix data update frequency: flexibly modulate the target dot matrix data update frequency using a target dot matrix data update frequency flexible modulation algorithm, and at the same time create a cycle formation mechanism using a dot matrix positioning posture database.

[0009] Preferably, the elimination of false targets in step S1 is actually performed based on actual measured distance data between targets.

[0010] Preferably, in step S2, the transient coordinate system corresponding to each positioning measurement period has no direct correlation with other transient coordinate systems.

[0011] Preferably, the dot matrix positioning relationship diagram in step S2 is only an independent presentation of the current transient position and orientation measurement data.

[0012] Preferably, in the dot matrix positioning relationship diagram in step S2, the coordinate system changes as the time period passes, but the dot matrix positioning state of the target group maintains a smooth migration.

[0013] Preferably, the dot matrix positioning transient database creation period P in step S2 is also the positioning posture graph update period.

[0014] Preferably, the basic supporting factor of the system capacity in step S3 is that the creation cycle of a dot matrix positioning posture database is less than 300 milliseconds.

[0015] Preferably, the specific operation of the target dot matrix data update frequency flexible modulation algorithm in step S4 is: the dot matrix positioning posture database creation cycle is X milliseconds, and the data update frequency actually presented by the system front end is X / 10 times per second. If the update frequency is relaxed, such as X / 20 times per second, the system capacity can be doubled.

[0016] The beneficial effects of the present invention are as follows: the present invention does not need to rely on fixedly deployed positioning base stations or anchor points, all equipment moves dynamically with the operating personnel, and at the same time the system perceives the real-time dot matrix position relationship of the operating members with high precision, including the real-time distance and orientation relationship between the members, and can access the data of the external global positioning system at any time to perform integrated high-precision positioning, which is conducive to application in working environments where temporary installation of fixed positioning base stations is not allowed.

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1-2 As shown, a high-precision dot matrix positioning method without a base station includes the following steps:

[0023] S1. Creation of transient dot matrix positioning: First, select the transient reference coordinate system, create the target group dot matrix positioning data system, and eliminate false targets.

[0024] S2. Transient dot matrix positioning state migration: Then determine multiple positioning measurement cycles, and establish a dot matrix positioning relationship diagram. Then, use the passage of time to observe the changes in the coordinate system, and at the same time establish a dot matrix positioning transient database to create a cycle P.

[0025] S3. Adopt in-band communication mechanism: In addition to the fixed processing delay of the processing chip, it provides a sub-millisecond dot matrix positioning attitude database creation cycle and provides basic support for system capacity.

[0026] S4. Flexibly modulate the target dot matrix data update frequency: flexibly modulate the target dot matrix data update frequency using a target dot matrix data update frequency flexible modulation algorithm, and at the same time create a cycle formation mechanism using a dot matrix positioning posture database.

[0027] The elimination of false targets in step S1 is actually performed based on the actual measured distance data between targets.

[0028] The transient coordinate system corresponding to each positioning measurement period in step S2 has no direct correlation with other transient coordinate systems.

[0029] The dot matrix positioning relationship diagram in step S2 is only an independent presentation of the current transient position and orientation measurement data.

[0030] Among them, in the dot matrix positioning relationship diagram in step S2, the coordinate system changes with the passage of time period, but the dot matrix positioning state of the target group maintains smooth migration, thereby ensuring that the dot matrix positioning data of the target group remains updated and moved in real time, smoothly and with high precision, presenting a high-precision real-time dot matrix positioning state diagram to the user.

[0031] The dot matrix positioning transient database creation period P in step S2 is also the positioning posture graph update period.

[0032] The basic supporting factor of the system capacity in step S3 is that the creation cycle of a dot matrix positioning posture database is less than 300 milliseconds.

[0033] Among them, the specific operation of the target dot matrix data update frequency flexible modulation algorithm in step S4 is: the dot matrix positioning posture database creation cycle is X milliseconds, and the data update frequency actually presented by the system front end is X / 10 times per second. If the update frequency is relaxed, such as X / 20 times per second, the system capacity can be doubled.

[0034] Specifically, when performing actual operations:

[0035] First, create a transient dot matrix positioning system, select a transient reference coordinate system, create a target group dot matrix positioning data system, and eliminate false targets. At the same time, eliminating false targets is based on the actual measurement distance data between targets. For example, Figure 1 As shown, it is a schematic diagram of the process of creating the transient dot matrix positioning state of the target group.

[0036] Then, the transient dot matrix positioning state migration is performed, multiple positioning measurement cycles are determined, and a dot matrix positioning relationship diagram is established. Then, the changes in the coordinate system are observed by the passage of time periods, and a dot matrix positioning transient database creation period P is established. The dot matrix positioning transient database creation period P is also the positioning attitude diagram update period. At the same time, the transient coordinate system corresponding to each positioning measurement cycle has no direct correlation with other transient coordinate systems, and the dot matrix positioning relationship diagram is only an independent presentation of the current transient position and orientation measurement data. In addition, as the time period passes in the dot matrix positioning relationship diagram, the coordinate system changes, but the dot matrix positioning state of the target group maintains a smooth migration, thereby ensuring that the dot matrix positioning data of the target group is updated and moved in real time, smoothly and with high precision, and presenting a high-precision real-time dot matrix positioning state diagram to the user, such as Figure 2 As shown, it is a schematic diagram of the transient dot matrix positioning state transition of the target group.

[0037] Then, the in-band communication mechanism is used for communication operations. In addition to the fixed processing delay of the processing chip, a sub-millisecond dot matrix positioning attitude database creation cycle is provided, and the basic support for system capacity is provided. At the same time, the basic support factor for system capacity is that the creation cycle of a dot matrix positioning attitude database is less than 300 milliseconds.

[0038] Finally, the target dot matrix data update frequency is flexibly modulated, and the target dot matrix data update frequency flexible modulation algorithm is used to flexibly modulate the target dot matrix data update frequency, and the dot matrix positioning attitude database creation cycle is used to form a mechanism. The specific operation of the target dot matrix data update frequency flexible modulation algorithm is: taking the 100 millisecond dot matrix positioning attitude database creation cycle as an example, the data update frequency actually presented by the system front end is 10 times per second. If the update frequency is relaxed, such as 5 times per second, the system capacity can be doubled.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
