In this embodiment, the original monitoring information collected by the terminal device may include coordinates (x, y, z) of the current coordinate point and a height z of the current coordinate point. As shown in fig. 2, the collection steps are as follows:
s1, acquiring plane coordinates (x, y) of the current coordinate point based on the Beidou positioning module;
step S2, acquiring the height coordinate z of the current coordinate point based on the barometer;
in step S3, (x, y, z) is output as the coordinates of the current coordinate point.
That is, terminal equipment department can establish big dipper orientation module and barometer, and can regard as current coordinate point and output with the plane coordinate that big dipper orientation module provided and the altitude coordinate that the barometer acquireed better, so can possess the measurement accuracy of preferred.
Meanwhile, the barometer is an existing device that obtains the height of the current measurement position based on the air pressure-height formula by comparing the measured air pressure value with the reference air pressure value when measuring the height. The most significant source of measurement error is the variation in the baseline barometric pressure value. The sea level atmospheric pressure value, which is the reference atmospheric pressure value, is influenced not only by the weather conditions at the present time but also by the time, i.e., the daily deterioration. By the method in the embodiment, the sea level air pressure value under the historical meteorological conditions of the same region can be preferably used as a reference to correct the reference air pressure of the barometer, so that the output accuracy of the barometer can be preferably improved.
In order to realize high-precision output of the barometer, step S2 of the present embodiment is performed as follows:
step S21, establishing a climate model, wherein the climate model is used for representing the corresponding relation between the weather information sequence at the historical moment and the sea level air pressure value;
step S22, acquiring a time meteorological information sequence of the current time based on the Beidou positioning module, and judging historical sea level air pressure values under the historical time with the most similar time meteorological information sequence and the current time from the weather model based on similarity;
step S23, comparing the current reference air pressure in the barometer with the historical sea level air pressure value obtained in the step S22, if the comparison result is within the set error range, using the current reference air pressure value as the reference air pressure of the barometer, and if the comparison result exceeds the set error range, using the historical sea level air pressure value as the reference air pressure of the barometer;
in step S24, the barometer obtains the barometric pressure value of the current altitude and obtains the altitude of the current coordinate point in combination with the reference barometric pressure as the altitude coordinate z.
By establishing a climate model, the current reference air pressure in the barometer can be compared with the sea level air pressure value at the historical moment with the same or similar meteorological conditions, an error range can be set, and if the comparison result is within the error range, the current reference air pressure is judged to be effective, so that the altitude of the current coordinate point is calculated; if the comparison result exceeds the error range, the current reference air pressure can be replaced by the historical sea level air pressure value, and the altitude of the current coordinate point is calculated; therefore, the measurement accuracy of the barometer can be improved better.
In this embodiment, can acquire the meteorological information of current moment through big dipper orientation module to can construct the meteorological information sequence of current moment based on this. Then the weather information sequence at the moment can be input into the weather model, so that the weather information sequence at the moment at the historical moment which is most similar to the weather information sequence at the moment at the current moment is matched, and then the historical air pressure value at the corresponding historical moment can be output, so that the comparison between the historical sea level air pressure value and the current reference air pressure can be preferably realized.
In step S22 of the present embodiment, the current time weather information sequence is matched with the historical time weather information sequence, and after the most similar historical time weather information sequence is matched, the climate model can output the historical time and the historical sea level air pressure value corresponding to the historical time weather information sequence. Therefore, the rule for determining the error range in the present embodiment can be based on the following:
1. judging whether the time difference between the historical time and the current time reaches a set time threshold value, such as 30 min;
2. and judging whether the air pressure difference between the historical sea level air pressure value and the current reference air pressure reaches a set air pressure threshold value, such as 0.05 hPa.
If the rule 1 is not satisfied (that is, the difference value does not reach the set threshold), it indicates that the historical time to which the time weather information sequence of the historical time most similar to the current time weather information sequence matched in the historical data belongs is within the allowable error with the current time, that is, the matched time weather information sequence of the historical time is valid, and the historical sea level air pressure value corresponding to the time weather information sequence of the historical time can be used as a reference to be compared with the current reference air pressure.
If rule 1 is not satisfied, and if rule 2 is not satisfied (i.e., the difference value does not reach the set threshold), it indicates that the current reference air pressure is valid and can be used as the reference air pressure of the barometer.
If the rule 1 is not satisfied, if the rule 2 is satisfied (that is, the difference value reaches the set threshold), it indicates that the current reference barometric pressure is invalid, and the corresponding historical sea level barometric pressure value is used as the reference barometric pressure of the barometer.
If the rule 1 is satisfied (that is, the difference value reaches the set threshold), the historical time to which the weather information sequence of the matched historical time belongs and the current time exceed the allowable error range are described; i.e. not matching to a historical time similar to the meteorological conditions at the current time. At this time, the reference pressure P of the barometer is calculated and obtained according to the following formularef：
In the above formula, U represents the number of years included in the history data, LτRepresenting historical sea level barometric pressure values at the same historical time as the current time,represents LτWeight of (e ∈)τAnd the Euclidean distance between the time meteorological information sequence at the current time and the time meteorological information sequence at the historical time at the same time.
Based on the above, the historical sea level at all the historical times at the same time can be preferably determinedThe air pressure value is weighted and calculated, and the result is used as the reference air pressure P of the barometerref。
Through the method, the influence of weather conditions and daily poor weather conditions on the reference air pressure can be fully considered, so that the reference air pressure of the barometer can be better calibrated, and the measurement accuracy can be better improved.

Through the above, noise can be eliminated better, so that the measurement precision can be improved better.
Step S212a of the present embodiment specifically includes the following steps,
step S212a1, weather information sequence GαβThe daily sequence of each meteorological index is subjected to Fourier series fitting, the fitting formula is as follows,
wherein Q isαβ(beta) is a solar weather information sequence GαβA fitting function of a specific index of (1); a. thelAnd BlFourier coefficients are obtained by fitting; l is expressed as Fourier order, and p is the value of the Fourier order; omegalThe value is a multiple of 4 for a preset parameter;

Through the method, the day parameters which have little influence on the year parameters can be better eliminated, so that invalid data can be better eliminated, and the size of the data is reduced.
Wherein, the value of l can be 4 or 8.
Here, the threshold set in S212a2 can be set to a constant such as 0.05.
By the step S212a2, A can be eliminatedlAnd BlSolar weather information sequence G approaching zeroαβTherefore, the day parameters which have little influence on the year parameters can be better rejected.
Step S212b of the present embodiment specifically includes the following steps,

By the above, the daily weather information sequence G can be preferably correctedαβProcessing the data to eliminate invalid time meteorological information sequence LαβγThus, data cleansing can be preferably achieved.
In this embodiment, the time weather information sequence is a numerical sequence of a plurality of weather indicators, the day weather information sequence is a sequence of time weather information sequences of all times of the day, and the year weather information sequence is a sequence of day weather information sequences of all days of the year. Therefore, a multi-index time meteorological information sequence can be constructed, and the data processing precision can be improved better.
In this embodiment, the plurality of meteorological parameters include one or more of temperature, humidity, wind direction, wind speed, and solar radiation. It is possible to preferably consider various factors that affect the air pressure.
In this embodiment, in step S22, the similarity determination is performed on the time weather information sequence based on the euclidean distance. The similarity determination can be preferably realized.
To further illustrate the method in this example, a specific example is described below.
In this particular embodiment, the temperature (Pm) is selected1) Humidity (Pm)2) Wind direction (Pm)3) Wind speed (Pm)4) And solar radiation (Pm)5) And constructing a time meteorological information sequence as a meteorological index.
Time weather information sequence L for one historical timeαβγIt is then:
wherein the content of the first and second substances,andrespectively indicate the temperature (Pm) at the time of day [ gamma ] on day [ beta ] of the year [ alpha ]1) Humidity (Pm)2) Wind direction (Pm)3) Wind speed (Pm)4) And solar radiation (Pm)5) The numerical value of (c).
The time weather information sequence of the current time t can be expressed as:
wherein the content of the first and second substances,andrespectively representing the temperature (Pm) at the current time t1) Humidity (Pm)2) Wind direction (Pm)3) Wind speed (Pm)4) And solar radiation (Pm)5) The numerical value of (c).
Therefore, when performing similarity matching, the calculation formula of the similarity (euclidean distance) is:
the similarity between the current time weather information sequence and the historical time weather information sequence is calculated one by one, and the time weather information sequence with the minimum similarity is the matched historical time weather information sequence.
Wherein, for a weather information sequence GαβIt is then:

wind speed (Pm)4) The daily sequence of the meteorological indexes is as follows:
solar radiation(Pm5) The daily sequence of the meteorological indexes is as follows:
the step S212a1 preferably realizes the fitting of the day sequence of each weather indicator, and the Fourier coefficient A of the day sequence of any weather indicatorlAnd BlWhen the solar weather information is within the set threshold value, the solar weather information sequence G of the day is determinedαβAnd (5) removing.
In step S212b, the confidence level is calculated for each weather indicator day series value, and if the confidence level of any weather indicator is less than 0.95, the weather information series L is determined for the time of the whole historical time of the weather indicatorαβγAnd then the samples are removed.
By the method in the embodiment, historical meteorological data can be preferably processed, a climate model is established, and the reference barometric pressure of the barometer is corrected by considering the difference between the time value of the current time and the meteorological condition and the time value of the historical time and the meteorological condition, so that the influence of the meteorological condition and the daily difference on the reference barometric pressure can be preferably and fully considered, and the positioning accuracy of the barometer can be preferably improved.
Through the method, the accurate positioning coordinate point and the accurate height value can be obtained better, the data can be sent to the data processing subsystem through the data receiving and distributing subsystem, and then sent to the processing platform module, and therefore accurate positioning of personnel wearing the terminal equipment can be achieved better.
The terminal equipment can be provided with a local processing module, and the climate model can be arranged in the local processing module, so that the terminal equipment can realize the correction of the barometer locally.
In addition, because big dipper orientation module is being difficult to carry out signal coverage indoor, so when the scene got into indoor, it is difficult to realize the preferred location to on-the-spot personnel, so terminal equipment department can also set up first ultrasonic ranging sensor and second supersoundA wave distance measuring sensor, a first ultrasonic distance measuring sensor for collecting the distance h from the top of the floor to the terminal equipment1The second ultrasonic ranging sensor is used for collecting the distance h from the bottom of the floor to the terminal equipment2And the distance h1And a distance h2Can also be sent to a processing platform module, which can determine the floor F on which the field personnel are located based on the following formula:
wherein the content of the first and second substances,h' is the vertical distance between the first ultrasonic ranging sensor and the second ultrasonic ranging sensor for rounding up, h0Is the altitude of the first floor.
In addition, a gyroscope sensor can be arranged at the terminal equipment (actually, the Beidou positioning module is provided with a gyroscope unit). Therefore, the terminal equipment can also acquire the inclination angle theta of the terminal equipment in the vertical direction and send the inclination angle theta to the processing platform module, so that the processing platform module can preferably consider the inclination of the terminal equipment, and further realize the correction of the floor height delta h, namely delta h (h ═ h)1+h2+h’)cosθ。
It can be understood that the altitude h of the first floor is0The value is constant, so that the value can be generated by presetting.
