Specifically, the acquisition station 17 is fixed to the bottom of the housing 15 of the node detector, the rectifier 12, the wireless receiving chip 13 and the fast charging chip 14 are fixed on the first fixed panel 18 located at the bottom, and the receiving metal coil 11 is fixed on the first fixed panel 18 located at the top.

[0028] Preferably, two ends of the receiving metal coil 11 are electrically connected to the input end of the rectifier 12 via a first connecting line 19 .

[0029] Based on the above-mentioned node-type detector with wireless charging function, the present invention also provides a wireless charging device for the node-type detector.

[0030] like Figure 2As shown, a wireless charging device 2 of a node-type detector is used to wirelessly charge the node-type detector 1 with a wireless charging function as described above, including a transmitting metal coil 21, a power regulating and rectifying chip 22 and a wireless transmitting chip 23; the transmitting metal coil 21 matches the receiving metal coil 11 in the node-type detector 1 with a wireless charging function as described above, the two ends of the transmitting metal coil 21 are electrically connected to the output end of the power regulating and rectifying chip 22, the input end of the power regulating and rectifying chip 22 is electrically connected to the output end of the wireless transmitting chip 23, and the input end of the wireless transmitting chip 23 is used to connect to a power supply.

[0031] In this specific embodiment:

[0032] Preferably, the wireless charging device 2 also includes a wireless charging device shell 24, and a second fixed panel 25 is provided in the wireless charging device shell 24, and the second fixed panel 25 divides the wireless charging device shell 24 into upper and lower cavities, and the power regulation and rectification chip 22 and the wireless transmitting chip 23 are both fixedly installed in the lower cavity of the wireless charging device shell 24, and the transmitting metal coil 21 is fixedly installed in the upper cavity of the wireless charging device shell 24.

[0033] Preferably, two ends of the transmitting metal coil 21 are electrically connected to the output end of the power regulating and rectifying chip 22 via a second connecting line 26 .

[0034] Figure 3 The present invention is a block diagram of the overall circuit structure of a node-type detector with wireless charging function and a charging device thereof.

[0035] When working, firstly, a node-type detector 1 with a wireless charging function of the present invention is placed upside down (with the tail facing upward) on a wireless charging device 2 of a node-type detector of the present invention, and the power is turned on to start charging the detector through the principle of electromagnetic induction.

[0036] During operation, after the external power supply is turned on, the wireless transmitting chip 23 of the wireless charging device 2 cooperates with the power regulation and rectification chip 22 to automatically control the voltage and frequency in the circuit. According to different conditions such as the AC or DC power supply connected to the circuit, the high-frequency alternating current generated by the transformation is transformed through a rectification or high-frequency inverter circuit and input into the transmitting metal coil 21. When the current flows through the transmitting metal coil 21, the transmitting metal coil 21 converts electrical energy into magnetic energy to generate an alternating magnetic field.

[0037] The node detector is inverted 1 (with the tail facing upward) on the wireless charging device 2. When the magnetic lines pass through the receiving metal coil 11, the receiving metal coil 11 is cut by the alternating magnetic field, thereby generating an alternating current inside the circuit. The alternating current flows into the subsequent circuit after coordinated regulation by the rectifier 12 and the wireless receiving chip 13, and then is regulated by the fast charging chip 14, automatically identifying the fast charging protocol supported by the battery pack of the collection station, and then automatically adjusting the output voltage and current, thereby realizing fast charging of the node detector.

[0038] In the present invention:

[0039] The tail vertebra 16 and the collection station 17 of the node detector use the original equipment of the node detector. The housing 15 of the node detector is made of corrosion-resistant, sealed and waterproof materials, such as galvanized steel, steel-plastic composite materials, etc., with a length and width of about 0.15-0.2m and a height of about 0.2-0.3m. The wireless receiving chip 13 uses the XKT-901 model chip, which has the function of frequency modulation and can adjust the voltage and frequency in the input circuit. The fast charging chip 14 uses the IP6505 model chip, which is a buck converter integrated with a synchronous switch. It supports 11 output fast charging protocols, including the mainstream QC3.0 and FCP. Its output is CV / CC mode. When the output current is less than the set value, the output CV mode and output voltage remain unchanged; when the output current is greater than the set value, the output CC mode and output voltage are reduced, and the fast charging protocol supported by the output terminal access device is automatically identified, and then the output voltage and current are automatically adjusted. The rectifier 12 is a Schottky rectifier, which is a diode, also called a Schottky barrier diode, and has the characteristics of short reverse recovery time and low forward conduction voltage drop. The receiving metal coil 11 is a copper coil, and the coil size is 0.02-0.03m in inner diameter and 0.1-0.17m in outer diameter.

[0040] The wireless charging device housing 24 of the wireless charging device is made of stainless steel metal material, which is easy to dissipate heat and keeps the charging process in a low temperature state. The length and width are about 0.2-0.25m, and the height is about 0.05-0.07m. The transmitting metal coil 21 is made of copper coil, and the coil size is 0.02-0.03m in inner diameter and 0.18-0.23m in outer diameter. The wireless transmitting chip 23 and the power regulating and rectifying chip 22 are a combination of XKT-901 chip and T5366 chip. The two can form a good transmitting control circuit to automatically control the electromagnetic wave transmitting voltage and frequency of the transmitting coil. Under the input of AC or DC power supply, the high-frequency alternating current generated by the transformation is transformed through a rectifier or high-frequency inverter circuit and input into the transmitting metal coil 21, which can ensure that the best output effect can be obtained under different voltages and different coil spacing conditions.

[0041] In the node-type detector and its charging device with wireless charging function of the present invention, the principle of electromagnetic induction is used to wirelessly charge the node-type detector, thereby simplifying the charging work steps, reducing the workload, and increasing the charging rate, thereby improving the efficiency of the entire project construction. In addition, the use of wireless charging mode can reduce the resource waste of power lines. A single charger can charge multiple power node-type detectors without occupying multiple power sockets; wireless charging has no universal contact design, which can avoid the risk of electric shock and ensure personal safety; wireless charging does not require an external charging interface, which effectively reduces dust and corrosive substances from entering the device and extends the service life of electronic products.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
