Detailed Description
To make the structure and advantages of the present application clearer, the structure of the present application will be further described with reference to the accompanying drawings.
Example one
Specifically, the embodiment of the present application provides a field operation management and control method based on an intelligent safety helmet, as shown in fig. 1, a positioning device and a speaker are installed in the intelligent safety helmet, and the field operation management and control method includes:
11. periodically receiving positioning information acquired by a positioning device;
12. comparing with a known working area based on the positioning information;
13. and controlling the loudspeaker to send out a control instruction corresponding to the comparison result.
In implementation, the application provides a field operation management and control method, which is characterized in that a positioning device and a loudspeaker are added on a safety helmet worn by an operation constructor, so that the position of the operation constructor can be acquired in real time, and meanwhile, a voice alarm prompt can be played by means of the loudspeaker under an emergency condition, so that the operation constructor is reminded at the first time, and the operation management and control effect of the field constructor is improved while the probability of operation accidents is reduced.
Specifically, the step 11 of periodically receiving the positioning information acquired by the positioning apparatus includes:
111. switching on a power supply loop of the positioning device according to a preset time interval;
112. judging the working state of the positioning device;
113. and receiving the positioning information acquired by the positioning device after judging that the positioning device is electrified to work normally.
In an implementation, the determining the operating state of the positioning apparatus by using the operating voltage as a monitoring standard is to avoid a positioning error caused by unstable signal reception when the positioning apparatus is just turned on, and specifically, the determining the operating state of the positioning apparatus includes:
after the positioning device is electrified, monitoring the working voltage of the positioning device in real time;
and when the working voltage is within the allowable range, judging that the positioning device is in a normal working state.
Optionally, comparing the location-based information provided in step 12 with the known work area includes:
121. longitude and latitude information in the positioning information and information sampling time corresponding to the positioning information are extracted;
122. filling the latitude and longitude information into a known working area, and judging the relative position relation between the positioning device and the working area.
In an embodiment, the comparing step is performed for determining a relative positional relationship between a current specific position of the work operator represented by the positioning device and the work area, and the determining step includes:
1221. extracting a reference point coordinate value on the boundary in the operation area and a fixed point coordinate value in the operation area;
1222. calculating a first distance between a real-time position point corresponding to longitude and latitude information in the positioning information and a fixed point coordinate value and a second distance between a reference point coordinate value and the fixed point coordinate value;
1223. and if the first distance is smaller than the second distance, determining that the positioning device is in the working area, and otherwise, determining that the positioning device is outside the working area.
The basis of the relative distance judgment is to use the relative distance between the reference point coordinate value and the fixed point coordinate value on the boundary as a reference for comparing the distance between the positioning device and the fixed point coordinate value. Namely, if the second distance corresponding to the former is greater than the first distance corresponding to the latter, the positioning device is judged to be in the working area, and on the contrary, the positioning device represents that the working constructor is positioned outside the working area.
Since there are many algorithms for determining the relative position relationship between the preset point and the known area, the embodiments of the present application cannot be exhaustive, and only an implementation for performing the determination based on the relative distance is provided here.
It is worth noting that if the positioning device is judged to be outside the working area, the information sampling time and the longitude and latitude information are packaged and sent to the monitoring center for image monitoring. The method is carried out in a manner that the working area is often a dangerous area, and the working constructors who are judged to be outside the working area need to pay attention, so that the method is shifted to an image monitoring manner so as to further determine the conditions of the working constructors.
and sending voice alarm information to a loudspeaker of the intelligent safety helmet outside the working area.
In implementation, a speaker arranged in the intelligent safety helmet is used for receiving voice alarm information sent to operation construction personnel outside an operation area, and after the operation construction personnel receive the voice alarm information, the current situation needs to be confirmed as soon as possible and safety measures need to be taken to avoid falling into a dangerous situation.
Furthermore, for the positioning device that has sent the voice alarm information, it is necessary to improve the positioning information acquisition frequency of the positioning device that has sent the voice alarm information, so as to improve the accuracy of position confirmation and take corresponding processing measures.
The embodiment of the application provides an intelligent safety helmet-based field operation management and control method, and the method adopts mature means such as a GPS/Beidou positioning technology and relies on advanced intelligent sensing equipment and an Internet of things terminal, can support automatic acquisition of information such as construction site personnel positioning, operation tracks and vital signs, supports a wireless communication mode to conduct personnel communication command, and is suitable for field intelligent personnel management and application in a construction site.

Example two
The embodiment of the present application further provides a method for performing error correction according to the positioning information after the positioning information is obtained, as shown in fig. 2, where the method specifically includes:
21. periodically receiving at least three positioning information acquired by a positioning device;
22. the position of the positioning device is corrected based on the positioning information.
In an embodiment, the step of correcting the position of the positioning device based on the positioning information is based on a linear fitting concept, and includes:
221. carrying out linear fitting on the received positioning information;
222. location information that is significantly distant from the fitted curve is replaced based on the curve data.
The traveling route of the operation constructor in the operation area is often regular, for example, a track line can be determined by longitude and latitude data in two positioning information, a simple quadratic curve can be determined by three longitude and latitude data, and the remaining positioning information can be analyzed to judge whether the positioning drift occurs on the same fitting curve or not and needs to be deleted.
A simpler linear fitting approach, such as a least squares approach, may be used here to reduce the computational pressure.
Linear fitting is a form of curve fitting. Let x and y both be the quantities observed, and y be a function of x: and y is f (x; b), the curve fitting is to find the optimal estimated value of the parameter b through the observed values of x and y, and to find the optimal theoretical curve y is f (x; b). When the function y is a linear function of i with respect to b, such a curve fit is said to be a linear fit. In order to obtain the inherent regularity between data or to predict the expected data using current data, a continuous curve is used to approximately describe or compare the functional relationship between the coordinates represented by the discrete point groups on the plane, and the corresponding problem in the high-dimensional space also belongs to this category.
The sequence numbers in the above embodiments are merely for description, and do not represent the sequence of the assembly or the use of the components.
The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
