- the central terminal activates the warning means associated with said tag and optionally activates one of the warning means associated with the other tags.
- the method of the invention comprises at least one or, where appropriate, an appropriate combination, of the following additional characteristics:
- the red zone boundary is determined: either by using a location of the reference terminals in the reference frame
- the border of the orange zone is determined from the red zone boundary by creating an inner polygon by homothety, the distance corresponding to the withdrawal being between 50 cm and 1 m;
- the reference XY is established in the following way by the central terminal: a first anchor, preferably the central terminal, is arbitrarily assigned to the coordinate (0, 0); a second anchor at a measured distance d is assigned to the coordinate (d, 0); a third anchor is located from the two aforementioned anchors using the intersection of two circles from the respective distances of the third anchor from the two anchors mentioned above, one of the two possible intersections being chosen as the position of the third anchor, the selected position being determined arbitrarily, for example the position of positive Y coordinate; the following anchors are located from the first three anchors using a trilateration algorithm, the trilateration algorithm preferably being the algorithm described below for locating the tags; in the step of determining the position of the tags in the XY coordinate system, to assign to each of these positions a location either in the green zone, in the orange
- a third aspect of the present invention relates to a device for the personal or collective protection of persons in a potentially dangerous three-dimensional (3D) zone, comprising:

- Figure 7 schematically represents the principle of the algorithm for the border filtering.
- FIG. 8 illustrates how, according to the invention, the relative position of the tag with respect to the boundary is determined using Jordan's theorem.
- the system according to the present invention can warn the minor or any other person located near a danger zone.
- This warning is via a transceiver, or "tag” or tag, worn by the person directly on the body or on personal protective equipment (PPE).
- PPE personal protective equipment
- the transceiver or the tag signals the danger by luminous, acoustic and vibratory signals combined or not according to the dangerousness.
- the operation requires that each transceiver be able to locate with respect to the danger zone.
- several reference points, also called “anchors” are placed in the field.
- a configuration step preferably consists of moving a special transceiver called a tracer along the boundary between the danger zone and the safety zone. This step allows the system to record a set of positions that ultimately define the warning limit.
- the recording is done within a central terminal placed preferably in a suitcase.
- the location of the transceivers with respect to the terminals is performed by a trilateration system.
- a feature of the invention is that the definition of the area is during the tracing while the terminals were initially arbitrarily laid and that the position of the reference terminals is unknown during the installation of the device and will remain so throughout the operation of the device. The resolution of this apparent contradiction is an element of the invention.
- a second feature is the protection of the system against measurement errors by the redundancy of measurements and the redundancy of communication channels between the terminals, the (or) receiver (s) and the bag.
- Figure 1 schematically shows the various components of the system of the invention: a person 1 carrier of a tag 6 (located here in green zone), the reference terminals 3, the central terminal (and the bag) ) 4, the tracer 5 and the three safety zones 7, 8, 9.
- the problem to be solved is to warn one or more people that they are possibly in danger because of their position. This position must be obtained quickly, accurately (+/- 10 cm for example) indoors and outdoors. This last point excludes any solution based on a system of geolocation (GPS).
- GPS geolocation
- the danger is defined according to the position occupied by the person (s). More precisely, it is desired to map, according to the invention, a given space into three zones:
- the proposed solution is thus based on a set of reference terminals which are distributed more or less uniformly in the area in which one wants to achieve the positioning of people.
- These reference terminals communicate with each other and also communicate to a central terminal. It is this central pillar that orchestrates the entire system. In a preferred implementation, it is considered to place this central terminal in a suitcase and provide a screen, touch or not, and pushbuttons.
- the reference terminals are also capable of measuring the distance separating them by means known to those skilled in the art.
- One solution, for example, is to use UWB radio transmitters or ultrasonic transducers with a TOF (time of flight) method.
- UWB technology can evaluate a degree of reliability over the distance returned as well as the presence of potential obstacles. This information is advantageously used to reject any calculation distances considered unreliable.
- the position of the anchors (xO, yO), (x1, y1), and so on. is known, as well as the respective distances of the tag with respect to these anchors: dO, d1, etc.
- the aim here is to determine the most probable position of the tag (xt, yt).
- the idea implemented according to the invention is to consider the anchors 2 to 2 and determine xt and yt from a pair of anchors i and j. Knowing the positions of the anchors i, j and the distances between these and the tag, respectively di and dj, it is possible to determine 2 potential positions for the tag, corresponding to the intersection of two circles.
- the algorithm for calculating these two positions is known to those skilled in the art (see, for example, http: //www.ambrsoft.GomfTricioCalcfGirGles2fGirGle2.htm).
- intersection conditions of the two aforementioned circles will be further imposed by adding a tolerance which represents a possible measurement error over distances. If these conditions are satisfied, continue the calculation, otherwise we consider that there is a measurement error and that the position of the tag can not be found using this pair of anchors i, j.
- the algorithm uses the other anchors k (k different from i, j) and determines for each anchor k the distance with respect to two estimated positions and compares it to dk.
- This step is illustrated in FIG. 2 involving 3 anchors A1, A2 and A3, the two possible positions for the tag with respect to A1 and A2 being denoted T1 and T2 respectively (reference numerals 61 and 62).
- a voting system is applied. We compare each of the distances between the estimated positions 61, 62 and the anchor k with dk. If the smallest difference is that of position 61, the score of position 61 is incremented by 1 point.
- This indeterminacy may be caused by a measurement error or by the fact that the two tag positions are close. In the latter case, the positions are averaged.
- the idea is to exploit the radio information to attach reliability to each distance measurement.
- Reliability is expressed as an estimate of error expressed itself in meters.
- the estimated error is at least:
- Adi Adi -Accuracy + todi WHERE
- di Power is related to the power received from the FP_Power "first path". The higher the power, the more likely it is to be near and in direct field and the lower the measurement.
- a logarithmic loss precision with the distance ie for example a loss of 1 cm of precision with the doubling of distance (-6 dB):
- the positioning algorithm is implemented four times by disturbing the measurements on di and dj in the following way: di ⁇ di ⁇ Adi,
- NPT can be set to 10 for example.
- yt ⁇ ij Pyt (ij) yt (ij).
- the user asks the system to check the placement of the terminals.
- the central terminal interrogates the set of reference terminals and asks them for the distance that separates them from each other (see above).
- Any location requires a reference mark. According to the prior art, it is still required that this marker be defined by assigning known positions to the reference terminals. The proposed invention, however, does not require this heavy constraint for a system that needs to be installed quickly.
- the central terminal determines an XY mark that will be used for further localization. This determination works in several stages (see also Figure 4):
- a terminal 10 preferably the central terminal (located in the case) is arbitrarily assigned to the coordinate (0, 0).
- a second terminal 20 which is at a distance d is assigned to the coordinate (d, 0).
- a refinement step is possible once all the coordinates of the determined terminals. This step aims to make the localization algorithm insensitive to the initial choice of terminals in steps 1), 2) and 3).
- the method which consists, in 2D, of considering a pair of anchors, to determine two possible positions by intersection of two circles and to use the other anchors by a distance voting mechanism to select a position among these 2 possible positions are easily generalized in 3D in a method which consists in considering a triplet of anchors, to determine two possible positions by intersection of three spheres and to use the other anchors by a mechanism of vote on the distances to select a position among these 2 possible positions.
- the mechanism of disruption of the two distances relative to pairs of anchors in 2D allows to obtain four disturbed positions
- the mechanism can be implemented on three distances from the triplet of anchors and allows to obtain nine disturbed positions.
- the path that defines the safety zone is in fact a projection on the X, Y plane, said zones being then cylinders (generalized).
- a safety zone would be defined on the ground floor by tracing the border and automatically reported to all floors.
- the anchors When creating the orthonormal landmark, the anchors are placed approximately, as indicated above, and the only information known are the distances between the anchors (dij) and the associated errors (Adij) - see the method described above where Di and Adi are respectively replaced by dij and Adij. Distances dij can be measured a large number of times (NMA) and are therefore accurate. For example, we can limit our to averaging the errors on the four central values of dij.
- the algorithm therefore has a series of anchors na whose positions it does not know but only the relative distances dij.
- the algorithm for determining the position of the anchors is as follows:
- each new anchor is positioned more and more precisely.
- all anchors are located on an orthonormal grid.
- the third anchor is chosen arbitrarily (see above), a mirror effect in x and y is possible but this has no influence on the boundary.
- the reference terminals are located on a touch screen in an XY coordinate system. It is then possible to draw on the touch screen a limit determining the red zone.
- the boundary is then defined as a set of closely spaced points joined by straight line segments.
- a device called tracer capable of communicating with the central terminal and the reference terminals is moved along the border by a person, walking for example.
- the central terminal interrogates periodically (typically 10x per second) the tracer and asks him for the distances that separate him from the reference terminals. From this information, the central terminal determines the successive positions of the tracer and thus creates a boundary by joining these positions approximated by line segments.
- the tracer could be embodied in the form of a wheel provided with a handle. The wheel could be advantageously used to send the aforementioned periodic signal which would correspond to a given displacement thereof.
- the danger zone is defined by connecting the four reference terminals by segments on the right and applying a homothety to define a larger rectangle that delimits the danger zone (red), as shown in Figure 5.
- the boundary is defined by a set of points connected by straight line segments.
- this represents 10,000 points and segments (if acquisition of 10 points per second). It is therefore advantageous to modify this boundary and replace it with a reduced number of points and segments by "filtering". This step is executed once and reduces the computational power required to determine the position of the tags relative to the border.
- Figure 6 shows an example of filtering of border (raw data obtained from the tracer 50 and border after filtering 51).
- the boundary consists of a list of coordinate points (xO, yO), (x1, y1), ... more or less ordered.
- This list represents a dense set of points which must be "lightened” to facilitate the determination of the position of the tag with respect to the border.
- the idea implemented by the invention is to browse these points and to condense them into a list of points spaced on average by a distance d.
- the algorithm is as follows (see FIG. 7):
- Figure 8 shows several examples where the number of intersections with the border is either even or odd.
- this method is very effective in the case of "noisy" borders that have micro-loops (see lower horizontal line and T3 tag). Determining a border of the orange zone
- the orange zone is defined by a distance parameter relative to the red zone. For example, we can decide that a tag enters the orange zone if it is less than 80 cm from the red zone. Given a boundary defined by a set of segments, it is easy for those skilled in the art to find the geometric algorithms necessary to determine whether or not a tag is within 80 cm of the boundary. Security in operation
- This tag is a mobile transceiver, capable of communicating with the central terminal and capable of measuring the distances that separate it from the reference terminals.
- the central terminal is able to periodically interrogate all the tags for which it provides protection, determine their position in the XY mark and evaluate this position with respect to the boundaries of the previously defined zones.
- the tags are advantageously provided with visual, auditory and / or vibratory signaling means.
- a tag enters an orange or red zone, it is notified by the central terminal.
- a tag enters a red zone, it can for example begin to vibrate, emit a shrill sound and indicate a red light signaling. Tags worn by other people will only emit a sound for example. Thus, the bearers of such a tag know that someone else in the group of people is in danger.
- the originality of the present invention resides first in the solution provided to not have to manually encode the location of the reference terminals.
- a second originality is the way the border is defined using a plotter and then filtered.
- the idea of making the system based on the collaboration of people is also innovative.
- UWB ultra-wideband signal
