As shown in FIG. 7 and FIG. 8 , the present invention further provides a water repellent water remodeling method for a swimming pool, which is used for forming the above-mentioned anti-smashing water system, comprising: in a swimming pool 1 , a plurality of arrays of first radio frequency identification electronic tag devices 2 are arranged At the bottom of the pool 1, the first radio frequency identification tag device 2 has a unique identification number and an address code indicating its location in the pool 1. And, at least one wireless signal collecting device 4 is disposed above the swimming pool 1 or the bottom of the swimming pool 1, and each of the first radio frequency identification electronic tag devices 2 is connected to the control terminal 5 through a plurality of data lines 6 at the bottom of the swimming pool 1, each first The radio frequency identification electronic tag device 2 further includes a rectangular waterproof floor 7 disposed at the bottom of the swimming pool 1, and the adjacent first radio frequency identification electronic tag devices 2 are spliced and positioned by a rectangular waterproof floor 7, and the data line 6 is embedded in the rectangular waterproof Inside the floor 7, or between the rectangular waterproof floor 7 and the bottom of the pool 1.

For example, in order to quickly establish a positioning network without destroying the underside of the original swimming pool. The first radio frequency identification electronic label device 2 is embedded in the inner plywood of the rectangular waterproof floor 7 (plastic wood floor), and then the plastic wood floor is laid on the bottom of the swimming pool in the form of laying the floor, and the plastic wood floor is formed by splicing a plurality of floor units. The upward facing side of the floor unit is provided with an LED glass lens for enabling the light beam of the LED lamp of the first radio frequency identification electronic label device 2 to be emitted, the floor unit having a waterproof joint, the signal data line of the first radio frequency identification electronic label device 2 and The power source is led out via a waterproof connector, in a waterproof connector that is connected to another floor unit, in such a manner that a plurality of first radio frequency identification tag devices 2 are connected in series, wherein the signal data cable is sheathed in the waterproof connector.

Figure 8 shows a cross-sectional view of the spliced plastic-wood floor panel in which the first radio frequency identification electronic tag device 2 is arranged, There are two spliced plastic wood floor units, and the left side of the floor unit has grooves on the left and right sides. Accordingly, the right side of the floor unit has bumps on the left and right sides, and the bumps are used for inserting into the grooves. To stitch together. Of course, for a floor unit, it is also possible to have a groove on one side and a bump on one side. In each of the floor units, a first radio frequency identification electronic tag device 2 is disposed as an example of the floor unit, and an LED glass lens is disposed on an upward side of the floor unit for causing the LED of the first radio frequency identification electronic tag device 2 The beam of light can be emitted. The floor unit has a waterproof joint, and the data line 6 of the first radio frequency identification electronic label device 2 is taken out via a waterproof joint and electrically connected to the waterproof joint of the floor unit, so that the first radio frequency identification electronic label device 2 is connected in series.

The first radio frequency identification electronic tag device 2 is networked in a grid manner, and is usually a local detection identification block in a square of 2M*2M or 3M*3M (which may of course also be a rectangle or a diamond shape, etc.). Accurate positioning of the target object can be performed according to the transceiver encoding of the first radio frequency identification electronic tag device 2. By adjusting the signal gain strength of each of the first radio frequency identification electronic tag devices 2, each of the first radio frequency identification electronic tag devices 2 can ensure an optimal local signal detection state, that is, the identification block can be effectively detected. The RFID tag signal inside. If the directional wireless transceiver 2 is laid out in other shapes, the effective identification block changes accordingly. In the case where the identification block is assumed to be square, each identification block is identified by four first radio frequency identification electronic tag devices 2 located at four vertices of the square, and the four first radio frequency identification electronic tag devices 2 can be used as one Identification unit. Each of the detectors included in each small unit will be connected to the bus through a serial connection, and finally the collected data will be aggregated to the control terminal 5, so that the present invention can convert the ordinary swimming pool to the prevention in the invention. Surabaya swimming pool.

9 to 11 are schematic views showing the implementation process of the flood prevention system of the present invention. As shown in FIGS. 9 to 11, wherein the first radio frequency identification electronic tag device 2 in the present invention is an RFID tag reader, and the second radio frequency identification electronic tag device 3 is an RFID electronic tag. When a swimmer wears an RFID tag into the pool, it is recognized by one of the identification units installed at the bottom of the pool, but the system typically does not handle normal security events. When the swimmer's head enters the water, the RFID tag sensor will start working, and the distance between the swimmer and the bottom RFID tag reader is also the most sensitive. When a swimmer enters an identification unit consisting of four RFID tag readers, the RFID tag will always be closest to one of the identified blocks and the signal is strongest (signal strength and number of receptions) Depending on the frequency), several RFID tag readers in one or a block closest to the RFID tag will have the strongest signal reception sensitivity, will determine the final precise position, and open a positioning area according to the event coding type. The opening of one or several RFID tag reader LEDs within the block. If the swimmer's head is out of the water, the pressure and time of the sensor will be zeroed, and will be activated again when the water enters the water again.

These RFID tags are worn on the head of the swimmer. The RFID electronic tag can be mounted on a swimming cap or goggle (fixed product) or in the form of a head strap embedded with an RFID tag in the form of an elastic strap. When a swimmer swims through an area in the pool, it is detected by the RFID tag reader at the bottom of the area pool. For each RFID tag that enters and passes, it will be detected by the identifier of the area to realize Accurate positioning, dynamic tracking, identification and SOS event information collection.

More specifically, when an RFID tag enters the bottom of any pool, the RFID tag reader is effectively probed. When the range is identified, the electronic tag code of the RFID tag will be recognized and recorded by the RFID tag reader. When the pressure transmitter embedded in the RFID electronic tag senses the water pressure, and the water pressure data will be combined with the length of the water into the water, the CPU logic control circuit generates different event coding types, and the CPU logic control circuit performs logic analysis on the change of time and pressure. Judging, different types of events are generated according to the result of the judgment, event codes are given to different types of events, and event codes are sent to the RFID tag reader at the bottom of the pool. At the same time, for different types of events, the LED of the directional wireless signal 2 at the bottom of the pool emits light of a corresponding color. For example, for normal events, the LED light may not light up or be displayed in green; for reminder events (such as swimming into deep water, or diving for 5 seconds), the LED light can be displayed as assuming yellow; for alarm events (eg diving) In 10 seconds, when the monitored water pressure and dive time exceed the peak value, the LED light can be displayed in red and can be flashed.

The control terminal 5 is configured to receive data of an RFID tag reader at the bottom of the pool, such as electronic tag encoding and event encoding of the RFID electronic tag. The control terminal 5 and the bottom RFID tag reader are connected by wire or wirelessly, and the wired mode is connected by, for example, an RS485 bus, and the wireless mode adopts a wired connection between the RFID tag reader at the bottom of the pool and the transceiver. Unified aggregation to the wireless signal transceiver relay end, and data exchange with the control terminal 5 through the 433M wireless mode relayed by the wireless signal transceiver relay terminal.

The control terminal 5 receives the information from the underwater RFID tag reader in real time, and determines which linkage action instruction is executed according to the different information content itself, so as to achieve the state of the fast drive linkage and the connected device being turned on and off. Preferably, the control terminal 5 performs real-time monitoring and integrated management, command release, data upload to a network PC server, etc., and then pushes client data through a network PC server, such as a human-machine interface client central control, electronic positioning map display. It displays the core functions of various types of information push, daily operation management, report statistics and summary.

In this embodiment, the safety time threshold is 10 seconds, and the safety water pressure threshold is 0.3 meters, but is not limited thereto.

As shown in FIG. 9, at this time, the swimmer floats on the water surface, and the data of the water pressure sensor in the second radio frequency identification electronic tag device 3 is substantially zero, which is a normal event. When the event is encoded as a normal event, the control terminal 5 does not activate the servo pan/tilt LED beam directing lamp 14 for linkage, that is to say, the normal encoding event intelligent central controller does not send data and related command signals like the LED pointing lamp device.

As shown in Figure 10, at this time, the swimmer dive down to 0.5 meters below the water surface and keep it for 3 seconds. At this time, the data of the water pressure sensor is 0.5 and the duration is 3 seconds, although the safety water pressure valve is exceeded. The value, but does not exceed the safe time threshold, so it is still a normal event.

As shown in FIG. 11, at this time, the swimmer is in a drowning state, and the safety time threshold and the safe water pressure threshold are both exceeded. When the event code rises to a high level reminding event, the control terminal 5 starts the linkage mechanism and goes to the servo cloud. The LED beam guiding lamp 14 sends the relevant linkage signal, and the servo pan/tilt LED beam guiding lamp 14 immediately starts and turns on the hypothetical yellow or red high-level beam to automatically project to the corresponding pool bottom wireless after receiving the first closing signal. The position of the signal transmitter 2 is such that the lifeguard can pay more attention or quickly lock the location of the possible drowning person and promptly rescue it.

Moreover, the second radio frequency identification electronic tag device 3 of the present invention can also distinguish the swimmers that are worn in advance. For example, the range of activities of the children swimmers is specifically limited to only in the shallow water area, and once the deep water area is entered, an alarm is issued, etc. I won't go into details here.

Figure 12 is a side elevational view of a second flood control system of the present invention. As shown in FIG. 12, the second flood prevention system of the present invention is different from the first flood prevention system in that the second flood prevention system is divided according to the deep water zone 1B of the swimming pool and the shallow water zone 1A, in the deep water zone. The first radio frequency identification tag device 2 is denser than the shallow water zone at the bottom of 1B. Since the usually dangerous drowning situation mainly occurs in the deep water area 1B, the densely-distributed first radio frequency identification electronic tag device 2 in the deep water area 1B can locate the drowning swimmer more accurately and timely, so as to timely implement rescue measures. Other technical features are the same as those of the first flood prevention system and will not be described here.

Figure 13 is a plan view of a third flood control system incorporating the present invention. As shown in FIG. 13, the third anti-water-repellent system of the present invention is arranged in a rectangular shape between the first radio-frequency identification electronic tag device 2 in the first anti-flooding system, and the third anti-smashing water system is in the swimming pool. At the bottom, the first radio frequency identification electronic tag device 2 is arranged in a matrix according to a triangular arrangement, and can also be positioned according to the first radio frequency identification electronic tag device 2 having the strongest signal at the three corners of the triangle. Other technical features are the same as those of the first flood prevention system and will not be described here.

Figure 14 is a side elevational view of a fourth flood control system of the present invention. As shown in FIG. 14, the fourth flood prevention system of the present invention is different from the first radio frequency identification electronic label device 2 in the first flood prevention system in that the data line 6 needs to be connected to the control terminal 5. Each of the first radio frequency identification electronic tag devices 2 in the drowning system may have an independent power source and a wireless communication module, and the first radio frequency identification tag device 2 performs wireless communication with the wireless signal collecting device 4, and then passes through the wireless signal collecting device 4 and the control terminal. The data line between 5 is transmitted to the control terminal 5, and in this configuration, it is not necessary to arrange the data line 6 at the bottom. The fourth flood prevention system of the present invention is very advantageous for retrofitting an existing old swimming pool without remodeling the bottom of the swimming pool 1 (laying cables), and only needs to follow the first radio frequency identification electronic label device 2 capable of wireless communication. The matrix arrangement is fixed to the bottom of the swimming pool 1 to achieve the effects of the present invention.

Figure 15 is a side elevational view of a fifth flood control system of the present invention. As shown in Fig. 15, in the fifth flood prevention system of the present invention, unlike the first flood prevention system, a wireless communication device is widely used in the fifth flood prevention system.

The first radio frequency identification tag device 2 at the bottom of the pool is connected to the first wireless signal transceiver relay 8 via a data line 6, and the LED beam directing device 14 and the alarm speaker 15 are connected to the third wireless signal transceiver relay 10, The wireless signal acquisition device 4 is connected to the fifth wireless signal transceiver relay 12, respectively. The control terminal 5 is connected to the second wireless signal transceiver relay terminal 9, the fourth wireless signal transceiver relay terminal 11, and the sixth wireless signal transceiver relay terminal 13 through the background server 16, respectively. The first wireless signal transceiver relay 8 and the second wireless signal transceiver relay 9 exchange data by wireless communication. The third wireless signal transceiver repeater 10 and the fourth wireless signal transceiver repeater 11 exchange data by wireless communication. The fifth wireless signal transceiver relay terminal 12 and the sixth wireless signal transceiver relay terminal 13 exchange data by wireless communication. In this structure, the cable layout is greatly reduced, the difficulty in constructing the flood prevention system is reduced, and the flexibility of the wireless signal acquisition device 4, the LED beam directing device 14 and the alarm speaker 15 is improved.

The first radio frequency identification electronic tag device 2 can be installed at the bottom of the swimming pool as a grid coordinate position point, and adopts a network format equal-proportional multi-point distribution installation manner to achieve partial or full coverage of the bottom of the swimming pool. By setting and adjusting the signal transmission gain intensity of the electronic tag, each electronic tag wireless signal transmission can ensure an optimal local effective range (local range is 2M*2M or 3M*3M as a square for effectively identifying the block) Each identification block has 4 electronic tags as one identification unit, and each electronic tag has a unique code identification code, and each identification code will be the only effective coordinate position in the grid. For each of the wearable second radio frequency identification electronic tag devices 3 that enters and passes, the second radio frequency identification electronic tag device 3 identifies and collects the electronic tag position code at the bottom of the pool, and passes the collected information through itself. The wireless radio frequency circuit is coupled to the wireless signal acquisition device 4 with the embedded antenna to achieve the core functions of precise positioning, dynamic tracking, identification, and SOS event information collection. The second radio frequency identification electronic tag device 3 is the only electronic sensing device worn on the body of the swimmer. When the embedded microsensor detects the change of the physical value of the pressure, the electronic transceiver will perform time and pressure through its own CPU logic control circuit. The difference changes are logically analyzed and judged, and the result of the judgment generates different types of event signal codes and together with the electronic tag position codes, the event signals are simultaneously transmitted to the wireless signal collecting device 4 and the underwater first radio frequency identification electronic tag device 2 unit. When the first radio frequency identification electronic tag device 2 and the wireless signal acquisition device 4 receive the code of any wearable electronic transceiver, the electronic tag code address code, and the different event codes, the LED of the first radio frequency identification electronic tag device 2 is first According to the event code, the colorful tube flashes for warning and reminding. At the same time, the fixed signal transceiver will send this information to the central controller end in real time, and finally the central control will analyze and lock the position, identity, event type, and automatically execute all the intelligent switch actions preset by the system.

In summary, the system of the present invention has the characteristics of high technical content, high integration, high degree of automation, and reduced number of security administrators, thereby effectively reducing the cost of the stadium personnel. The system is accurate and accurate in complex environment. Each unit module in the system has independent and intelligent judgment and control characteristics. Through simple and humanized technology management means, it is realized in the real sense of the Internet of Things. The typical construction and application of a modern technology swimming pool with a core theme.
