correspondingly, the step of determining the device coordinate points of the active electronic tags in the digital building plan according to the preset device positions, and displaying the device coordinate points and the corresponding device identifiers in the digital building plan to position the fire fighting devices specifically includes:
s401: extracting preset building floor information from the preset equipment position;
it can be understood that: because the electronic tags have the readable and writable functions, before the task is executed, a project manager or a fire protection maintenance worker can use the fire protection equipment maintenance positioning device to store the floor information (corresponding to the building data in a local or background database) and the equipment coordinate points (corresponding to the coordinate system of the digitized building plan) of each fire protection equipment in each corresponding electronic tag bound with the fire protection equipment;
s402: matching the current building floor information with each preset building floor information;

s403: removing the preset equipment position information which is not successfully matched;
s404: and determining the equipment coordinate points of the active electronic tags in the digital building plan according to the positions of the rest preset equipment.
It can be understood that, for example, currently, a user performs a device maintenance task on the 2 nd floor, and the user only needs to maintain the fire fighting devices on the 2 nd floor; but the terminal device held by the user receives the electronic tag signals of the 2 nd, 1 st and 3 rd floors simultaneously within the signal range; the processor only needs to screen out the coordinate position of the fire fighting equipment of the 2-storied building on the digital building plane map according to the floor where each fire fighting equipment is located and the equipment coordinate point, and the information of the 1-storied building and the 3-storied building can be shielded.

Referring to fig. 4, fig. 3 is a schematic flow chart of a method for positioning fire fighting equipment according to a third embodiment of the present invention, and the method for positioning fire fighting equipment according to the third embodiment of the present invention is provided based on the embodiment shown in fig. 3.
In this embodiment, after the extracting the preset device location and the device identifier of each active electronic tag from the tag signal, the method further includes:
s501: extracting signal intensity values from the tag signals, and calculating the distance between each active electronic tag and a user according to each signal intensity value;
correspondingly, after determining the device coordinate point of each active electronic tag in the digitized building plan according to each preset device position, the method further includes:
s502: and drawing circles by taking the distance between the active electronic tag and the user as a radius and the equipment coordinate point as a circle center, taking the intersection point of each circle as the current position coordinate of the user, and displaying the current position coordinate of the user in the digital building plan.
It should be noted that the network operating environment of the technical solution of the present invention may be a WIreless broadband WI-FI (WIreless-FIdelity) configured to receive the electronic tag signal, may be an ibeacon bluetooth base station configured to receive the electronic tag signal, and may also be a WIreless personal area network; in this embodiment, for example, a wireless broadband WI-FI is set up to receive an electronic tag Signal, an AP access point in a wireless lan can conveniently measure a Signal Strength value RSSI (received Signal Strength indication) of an electronic tag of a fire fighting device within a Signal range of the AP access point, where the RSSI is a relative value for measuring the Strength of a Signal for receiving the electronic tag of the fire fighting device, and the larger the received RSSI value is, the closer the electronic tag is to the AP access point can be basically indicated, and conversely, the smaller the RSSI value is, the farther the electronic tag is indicated; since there is a certain relationship between the RSSI value of the active electronic tag and the distance from the active electronic tag signal to the signal receiving end, the signal receiving end can calculate the distance between the active electronic tag and the active electronic tag according to the RSSI value (which can be regarded as the distance ratio between the reader and the electronic tag approximately).
It can be understood that a user holding a mobile terminal (a mobile terminal to be tested) executes a fire protection maintenance task on a certain company building, fire fighting equipment is placed on a walkway of the building at intervals, and each equipment is provided with a corresponding active electronic tag; the handheld mobile terminal (mobile terminal to be tested) is provided with an electronic tag reader-writer, the reader-writer has a function of collecting the RSSI value of the signal intensity value of the electronic tag, for example, the electronic tag is a common electronic tag reader-writer developed by an IMPINJ R2000 chip on the market;
in the above embodiment, the reader of the mobile terminal to be tested has analyzed the coordinate point (preset device location) of the active electronic tag, and when the user of the mobile terminal to be tested receives tag signal RSSI values of three active electronic tags, namely, the coordinate point a (x1, y1), the coordinate point B (x2, y2) and the coordinate point C (x3, y3), respectively, the distances d1, d2 and d3 from each active electronic tag to the mobile terminal (user) to be tested are calculated according to each RSSI value; therefore, each active electronic tag coordinate point is taken, namely, the point a (x1, y1) is taken as the center of a circle, the radius d1 is taken as the circle a, the point B (x2, y2) is taken as the center of a circle, the radius d2 is taken as the circle B, the point C (x3, y3) is taken as the center of a circle, and the radius d2 is taken as the circle C; the intersection point of the circle A, the circle B and the circle C is the current position coordinate D of the mobile terminal (user) to be detected, and the current position coordinate D of the user is displayed in the digital building plan.
In the specific implementation, taking a company with one floor as an example, fire fighting equipment is placed on a walkway of the floor at intervals, and each equipment is provided with a corresponding active electronic tag;
when a user executes a fire protection maintenance task, a handheld mobile terminal (a mobile terminal to be tested) is provided with a WI-FI positioning module so that an AP (access point) can receive a signal strength RSSI (received signal strength indicator) value of the mobile terminal; since signal propagation may be affected by refraction, reflection, diffraction, etc., the received signal strength is a superposition of signals propagated by various paths; sometimes the signal strength is large or small, which affects the accuracy of the system in calculating the distance from the active electronic tag to the mobile terminal to be positioned or calculating the distance from the active electronic tag to the AP access point.
In order to reduce the ranging error, the mobile terminal can be set to enable a reader-writer to read the RSSI value of the same active electronic tag more than once at the same position, and the RSSI values read for multiple times are averaged to determine the distance from the active electronic tag to the mobile terminal (user) so as to reduce the ranging error;
in addition, project responsible personnel can also build an AP access point at each corner of the building, south, east and north, make wireless communication connection between the background server and the mobile terminal to be tested, and the AP access points receive the RSSI values of the signal strength propagated by each active electronic tag; since the RSSI value and the coordinate point (preset device location) of each active electronic tag are known, the AP calculates the signal strength value P of the mobile terminal to be detected received by the AP access point according to the following formula:
wherein, p is the intensity of the signal intensity value of the mobile terminal to be tested; po is the received signal strength at distance do; do is the real distance from the AP access point to any active electronic tag; d is the real distance from the AP access point to the mobile terminal to be tested; η is the shading factor; n is the path loss coefficient, which is dependent on the surrounding environment, typically between 2.0 and 3.3;
assuming that there are 4 APs and m active electronic tags, the strength P of the pending tag received by the AP point is (AP1, AP2, …, APn), the strength vector of the t-th active electronic tag collected is St (St1, St2, …, Stn), and the euclidean distance between the mobile terminal to be tested and the active electronic tag St is:
the method comprises the steps of searching for 3 active electronic tags closest to a mobile terminal to be detected by comparing different Et, establishing a field intensity vector for the mobile terminal to be detected on 4 APs (AP1, AP2, AP3 and AP4) by the algorithm, and establishing a field intensity vector for each active electronic tag, namely, comparing Euclidean distances between the field intensity vector of the mobile terminal to be detected and the field intensity vectors of the active electronic tags, finding out 3 active electronic tags with the minimum Euclidean distance, and knowing specific positions of the 3 active electronic tags (in the past, records are recorded when the active electronic tags are placed). For 3 reference points, the radius of the reference points is not determined according to the strength of signals, but 3 circles are made by taking the reference points as the centers of circles and taking 3/4 lengths of the distance between the nearest active electronic tags (to determine that one active electronic tag is placed every few meters) as the radius, so that 3 situations without intersection points do not occur.
Since it may happen that 3 circles do not intersect at the same point, there are 3 possible relationships between the 3 circles: first, when 3 circles have a common area, the common area necessarily has 3 intersection points, and the 3 intersection points are used as a triangle, so that the coordinate of the tag to be detected is the coordinate of the inner center of the triangle. Second, when two intersect without a common area, there must be two common areas. And (3) taking the middle point of the connecting line of the two intersection points of the two circle intersection areas, and making a triangle by using the 3 middle points, wherein the inner center of the triangle is the coordinate of the inner center of the label to be detected. And thirdly, under the extreme condition that 3 circles do not intersect, discarding the circles, receiving the next group of the nearest 3 active electronic tags, and if the intersection condition is not found for 3 times, making the positions made by the 3 active electronic tags into a triangle, wherein the center of the triangle is the position of the tag to be detected.
Further, after the displaying the current location coordinates of the user in the digitized building plan, the method further comprises: responding to a selection instruction input by a user, and determining a target device coordinate point corresponding to the selection instruction; and calculating a route from the current position coordinate of the user to the coordinate point of the target device according to the coordinate point of the target device and the current position coordinate of the user, and displaying the route on the digital building plan.
It is understood that the processor may calculate a route from the current location coordinates of the user to the coordinate points of the target device according to the coordinate points selected by the user in the digitized building plan and the current location coordinates of the user, and the coordinates of the partition in the digitized building plan.
