In figure, 1- server ends, 2-AP equipment, 3- user equipmenies end, 4- monitoring clients.
Specific implementation mode
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
As the first embodiment of the utility model, a kind of indoor locating system based on LoRa finely positionings is proposed,
LoRa is the chip based on 1GHz ultra long haul low power consumption data transmission technologys below (Long Range), it uses linear frequency modulation
Spread-spectrum modulation technique is maintained as FSK (frequency shift keying) modulates identical low power consumption characteristic, but significantly increase communication away from
From, while improving network efficiency and eliminating interference, even if the terminal of that is, different frequency expansion sequences using identical frequency simultaneously
Transmission will not interfere with each other, therefore the concentrator/gateway (Concentrator/Gateway) researched and developed on this basis can
The data for receiving and processing multiple nodes parallel, greatly expand power system capacity.As shown in Figure 1, including：It is server end 1, multigroup
AP equipment 2, user equipment end 3 and monitoring client 4, wherein user equipment end 3 includes the wearable device with signal transmission function
And intelligent terminal, wearable device include positioning card, wrist strap and key chain etc., can be worn at, and carry out reality
When signal transmitting, the user equipment end 1 in the present embodiment is mainly emitted using 2.4G signals.And it is independent by being arranged
Micro power be powered, ensure signal stabilization.
Multigroup AP equipment 2 is produced with latticed array indoors everywhere in institute, and general rectangle produces institute, with 2 × 3 structure cloth
Office production each angle on；As another citing, by taking office building as an example, each office is provided with an AP equipment, is formed
Latticed AP device layouts；AP equipment 2 can be realized directly using router, without in addition increasing indoor AP equipment,
Reduce equipment cost.Having time probe and infrared distance measuring device are set in each AP equipment 2, and time probe includes that signal receives
Device, terminal information acquisition device, clock circuit and reservoir, signal receiver is for detecting the wireless communication that user equipment end is sent out
Number, terminal information acquisition device is used for when detecting the signal at user equipment end, parses equipment client information therein, above equipment
Client information includes equipment cognizance code, device type information etc., in memory by equipment end information storage.Further, exist
When signal receiver receives user equipment end signal, the temporal information in clock circuit also is stored in memory.Believing
It, will be stored in memory by the data transmission interface in AP equipment 2 after number receiver receives user equipment end signal
Equipment client information and temporal information are sent to server end 1.The user equipment that infrared distance measuring device is arrived by time probe in detecting
Relative position sends infrared signal to user terminal, and the signal by being reflected back is calculated into row distance, is set with verifying user
Standby position and distance between AP equipment 2.
Server end 1 includes clock circuit, time-delay calculation device, distance calculator and temporary storage and general storage
Device.When receiving the equipment client information and temporal information that single time probe is sent, first equipment client information and time are believed
Breath is sent to temporary storage and is stored.When multiple time probes receive the homogeneous signal that same equipment end is sent, i.e.,
When occurring the homogeneous signal that identical equipment is sent out occur in the information that multiple time probes are sent in temporary storage, time-delay calculation
Device start, transfer the temporal information of a plurality of time probe of the equipment end in temporary storage, calculate each time probe when
Prolong.Specifically, temporal information when new model is sent out is stored in the Signal coding of homogeneous signal, when time probe is with this
Between on the basis of information when, time-delay calculation device compares to count when each time probe to be received to the temporal information and benchmark of signal
Calculate the relative time delay of each time probe.After the relative time delay for calculating each time probe, Delay is sent to generally
It is stored in memory, distance calculator transfers Delay, and goes out the same use according to the time-delay calculation of each probe
Relative distance of the family equipment end 3 apart from each AP equipment, the relative distance finally by multiple time probes pass through triangulation location
Method calculates the position that the user equipment end 3 is located at this time.Location information and facility information are sent out by data transmission interface
It send into monitoring client 4.
Monitoring client 4 includes host and display screen, receives location information and facility information by host, and be shown in display screen
