The wireless signal sent is held, terminal information acquisition device 212 is used for when detecting the signal at user equipment end, and parsing is therein to be set
Standby client information, the said equipment client information include equipment cognizance code, device type information etc., equipment client information are stored in into storage
In device 214.Further, when signal receiver 211 receives user equipment end signal, by the time in clock circuit 213
Information also is stored in memory 214.After signal receiver 211 receives user equipment end signal, by AP equipment
Data transmission interface, the equipment client information and temporal information that are stored in memory 214 are sent to server end 1.
As shown in figure 3, server end 1 includes clock circuit 11, time-delay calculation device 12, distance calculator 13 and deposited temporarily
Reservoir 14 and general memory 15.When receiving equipment client information and the temporal information that single time probe 21 is sent, first
Equipment client information and temporal information are sent into temporary storage 14 to be stored.Same set is received in multiple time probes 21
During the homogeneous signal that standby end is sent, i.e., occur identical set occur in the information that multiple time probes 21 are sent in temporary storage 14
During the homogeneous signal that preparation goes out, time-delay calculation device 12 starts, and transfers a plurality of time probe of the equipment end in temporary storage 14
21 temporal information, calculate the time delay of each time probe 21.Specifically, it is stored with the Signal coding of homogeneous signal new
Temporal information when model is sent, when time probe 21 is on the basis of the temporal information, time-delay calculation device 12 visits each time
Pin 21 is compared when receiving the temporal information and benchmark of signal so as to calculate the relative time delay of each time probe.Calculate each
After the relative time delay of time probe 21, Delay is sent in general memory 15 and stored, distance calculator 13 is adjusted
Delay is taken, and same user equipment end 3 is gone out apart from the relative of each AP equipment according to the time-delay calculation of each probe
Distance, the user equipment end 3 now institute position is calculated by triangulation location finally by the relative distance of multiple time probes
In position.Positional information and facility information are sent into monitoring client 4 by data transmission interface.
Monitoring client 4 includes main frame and display screen, by main frame receiving position information and facility information, and is shown in display screen
On, by setting the signal occurrence frequency at user equipment end 3, to cause positional information to form track on a display screen, and should
The facility information at user equipment end 3 is identified above.
With above-mentioned technical proposal, due to being provided with multigroup AP equipment, pass through the letter between more AP equipment and user equipment end
Number obtain the time calculated, draw distance results, and the track point location at user equipment end, nothing are realized by multiple AP equipment
Base station equipment need to be increased in addition just can complete in indoor user equipment end trajectory calculation, and radiation is small, and cost is low.
As the second embodiment of the present invention, propose that a kind of calculated based on indoor occupant motion track in first embodiment is
The indoor occupant method of calculating movement trajectory of system, including：

Indoor production institute, Intelligent bracelet send 2.4Ghz signal code in real time, and the equipment that the Intelligent bracelet is carried in signal code
Information, when the benchmark in the signal numbering of secondary signal code and current Intelligent bracelet.Intelligent bracelet beforehand through with service
Device end carries out time calibration, and when forming benchmark, AP equipment equally carries out the calibration of time with server end in advance, to ensure the time
Uniformity, avoid calculation error, when AP equipment is communicated with server end, also in real time carry out the time calibration.Step
Rapid S2：The signal that AP equipment detection user equipment end is sent.Specifically, when entering computer capacity at user equipment end, AP equipment
Passage time probe detects the signal that user equipment end is sent in real time, detects user equipment end signal in AP equipment, parses it
In signal code, and add AP equipment in signal code and detect the time of signal, then be compiled as request instruction.Step
S3：AP device-to-servers end sends request after receiving signal.Compiled request instruction is sent to server end.Step
S4：Server end calculates tracing point.Wherein, the calculating of tracing point comprises the following steps again, step S401：Server end parses
Request instruction.Specifically, facility information, the user equipment end signal at user equipment end can be obtained by analysis request instruction
The temporal information that sends, user equipment end send the signal numbering of signal every time and AP equipment detects the temporal information of signal
Deng.Step S402：Server end calculates the time delay of each AP equipment.Specifically, when setting signal was sent on the basis of the time, according to
Each AP equipment compares to obtain the time delay of each AP equipment when receiving time and the benchmark of signal.Step S403：Server end
Calculate the distance between user equipment end and each AP equipment.By the time delay of each AP equipment, then pass through the meter that is multiplied with velocity of wave
Calculate distance.Step S404：Tracing point is calculated according to the distance between user equipment end and each AP equipment.In the present embodiment
Realize that tracing point calculates using triangulation location, that is, it is fixed according to distance when thering are more than the three AP equipment to receive same signal
Position goes out tracing point.Preferably, when more than three AP equipment of appearance are received with a signal, the calculating of tracing point is just started.
One skilled in the art will appreciate that the calculating of tracing point can also be realized using other localization methods.Step S5：Server end will
Tracing point information is sent to monitoring client.Meanwhile server end also sends out the facility information at user equipment end, user equipment end signal
The temporal information that goes out, user equipment end send the signal numbering of signal every time and AP equipment detects the temporal information hair of signal
Monitoring client is given to be shown.
Using above-mentioned technical proposal, due to being provided with multigroup AP equipment, by between more AP equipment and user equipment end
