[0034] 100 NFC module 400 power module

[0035] 200 state indicating lamp 500 CAN module

[0036] 300 main control chip, 600 communication antenna Detailed Implementation

[0037] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0038] The following description, with reference to the accompanying drawings, describes the data acquisition device, the authorization management system, and the aerial work platform machinery according to this application.

[0039] like Figure 1 As shown, this application provides a data acquisition device for use in an authorized management system for aerial work platforms. The authorized management system includes a control module. The aerial work platform includes a work platform, a turntable, and a boom connected between the work platform and the turntable. An electrical control box is installed on both the work platform and the turntable. The data acquisition device can be located in either the electrical control box of the work platform or the electrical control box of the turntable. The data acquisition device includes an NFC module 100, a status indicator light 200, a main control chip 300, and a power module 400. The NFC module 100 is used to collect the identity information of the operator performing the work platform operation. The status indicator light 200 is electrically connected to the NFC module 100 and is used to indicate the data acquisition status. The main control chip 300 includes a first interface, a second interface, and a third interface. The first interface is electrically connected to the status indicator light 200, and the second interface is electrically connected to the NFC module 100. The power module 400 is electrically connected to the third interface and has a first input terminal for supplying power to the main control chip 300. The main control chip 300 supports a maximum clock frequency of 144MHz, with 512KB of Flash and 144KB of SRAM. It has 64 pins and supports up to two CAN channels, primarily responsible for communication interface connection and output status control. The NFC module 100 supports three contactless communication protocols—type A, type B, and 15693—at a frequency of 13.56MHz, and supports encryption algorithms of the MIFARE and SH standards.

[0040] When an operator performs an authorization operation, the power module 400 supplies power to the main control chip 300. The NFC module 100 in the data acquisition device collects the operator's identity information, and the status indicator 200 provides corresponding indications of the collection status. The identity information collected by the NFC module 100 is sent to the control module in the authorization management system via the main control chip 300, thereby authorizing the operator to perform the operation. This avoids the risk of unauthorized personnel operating the equipment due to unfamiliarity with equipment malfunctions. In this application, the operator can monitor the collection status in real time during the identity information collection process, thus avoiding collection failures that prevent identification and improving the efficiency of information collection during the authorization management process.

[0041] In some embodiments, the collection device further comprises a CAN module 500 electrically connected with the control module, the CAN module 500 is in communication connection with the NFC module 100 and is used for sending the identity information to the control module. Wherein, the CAN module 500 realizes the interface signal output through the CAN transceiver TJA1042. In the process of collecting the identity information, the identity information collected by the NFC module 100 is transmitted and sent to the control module through the CAN module 500, so as to realize the transmission of the collected identity information.

[0042] In some embodiments, the master chip 300 further comprises a fourth interface, the fourth interface is electrically connected with the CAN module 500, and the power module 400 has a second input end for supplying power to the CAN module 500. It can be understood that the working power of the CAN module 500 comes from the power module 400, and the CAN module 500 needs to pass through the master chip 300 for signal conversion in the process of signal receiving. The master chip 300 connects a plurality of signal output and input modules, so as to realize a complete signal transceiver network.

[0043] In some embodiments, the power module 400 comprises a power supply, a first power supply circuit and a second power supply circuit; the first power supply circuit converts the input voltage of the power supply into a first preset voltage through a converter and supplies power to the state indicating lamp 200; the second power supply circuit converts the first preset voltage output by the first power supply circuit into a second preset voltage through a voltage stabilizer and supplies power to the CAN module 500.

[0044] It can be understood that the power supply of the power module 400 is divided into two parts, the first power supply circuit first converts the DCDC into 8.8V voltage to supply power to the LED lamp bead, and the other part is converted into 5V and 3.3V by the second power supply circuit through the LDO and then supplied to each subsystem. Wherein, the input voltage range is 8 to 32V, the maximum voltage capacity is required to be greater than 36V, and the working current is less than 2A. The first power supply circuit and the second power supply circuit have overcurrent and overtemperature protection functions, the working efficiency is greater than 90%, and the power heating condition is effectively reduced.

[0045] In some embodiments, the state indicating lamp 200 comprises a lamp bead and a driving circuit; the number of the lamp beads is multiple and they are connected in series; each lamp bead and the output end of the first power supply circuit are connected with a driving circuit, and each driving circuit is provided with an anti-reverse diode.

[0046] The standard indicator lights consist of three LEDs connected in series, while the power indicator lights consist of two LEDs connected in series. The MCU I / O port outputs control the NMOS transistor to turn on, thus driving the LEDs to illuminate. In one embodiment, the HSL101 and 102 indicator circuits have a total of 14 standard indicator lights: 5 red, 6 yellow, and 3 green. The HSL103 indicator circuit has a total of 12 standard indicator lights and four power indicator lights: 5 red, 5 yellow, and 2 green standard indicator lights, and 3 green and 1 yellow power indicator lights. The HSL104 indicator circuit has a total of 10 standard indicator lights and four power indicator lights: 4 red, 4 yellow, and 2 green standard indicator lights. Based on the LED on-state voltage drop of VF = 2.2V as specified in the datasheet, the LED on-state current IF = (8.8 - (2.2 * 3)) / 120 = 0.0183A. The rated current IF = 0.020A in the datasheet meets the requirements.

[0047] In some implementations, such as Figure 2 As shown, the CAN module 500 includes a communication circuit. The input terminal of the communication circuit is connected to the NFC module 100, and the output terminal is connected to the control module. A common-mode inductor or a TVS diode is provided on the communication circuit. This application enhances the anti-interference capability of the CAN bus, improves its protection capability and reliability, and can support a maximum baud rate of 1 MHz by adding a common-mode inductor or TVS diode to the communication circuit.

[0048] In some embodiments, the NFC module 100 includes an NFC chip, on which a modem circuit is integrated, the modem circuit having a communication frequency range of 12 to 14 MHz.

[0049] Preferably, the NFC chip integrates an analog modulation and demodulation circuit, with a communication frequency of 13.56MHz. After configuring a small number of peripheral circuits, it achieves data communication with the microcontroller via SPI.

[0050] In some implementations, an external communication antenna 600 is connected to the NFC chip, and the data acquisition distance of the communication antenna 600 ranges from 0 to 5 cm. By calculating the PCB impedance and quality factor, and matching the design of the communication antenna 600 on the NFC chip, practical use of this system shows that the effective card reading distance of the communication antenna 600 can reach a maximum of 5 cm. When the operator's card swiping distance is within 5 cm, the card information can be read.
