When the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the protection scope required by the utility model.

[0049] In the current mechanical equipment state detection system, wireless communication type sensors integrated with wireless communication modules are often used to reduce the number of wiring on the construction site. However, for some detection positions on the mechanical equipment, there may be a situation that the existing wireless communication type sensor with too large volume cannot be placed due to the narrow space.

[0050] Therefore, with reference to Figure 1 The utility model provides a split type mechanical equipment state detection component, in an embodiment of the utility model, the split type mechanical equipment state detection component comprises:

[0051] a gateway component 10, which is configured to establish a communication connection with an external terminal;

[0052] a rotation speed sensor 20, which is electrically connected to the gateway component 10 and is configured to detect a rotation speed of a motor of a mechanical device and output a corresponding rotation speed detection signal;

[0053] a plurality of vibration and temperature detection components 30, each of which comprises a vibration and temperature collection box 31 and a vibration and temperature sensor 32 electrically connected to the vibration and temperature collection box 31, and the vibration and temperature collection box 31 is wirelessly connected to the gateway component 10;

[0054] The vibration and temperature sensor 32 is configured to detect a temperature of the mechanical device and output a corresponding temperature detection signal wirelessly to the gateway component 10 through the vibration and temperature collection box 31, and is also configured to detect a vibration state of the mechanical device and output a corresponding vibration detection signal.

[0055] The gateway component 10 is configured to control the vibration and temperature detection component 30 to wirelessly transmit the vibration detection signal output by the vibration and temperature sensor 32 to the gateway component 10 according to the rotation speed detection signal.

[0056] In this embodiment, the rotation speed sensor 20 can be implemented by an optical rotation speed sensor 20, an electromagnetic rotation speed sensor 20, etc. The rotation speed sensor 20 is configured to detect a rotation speed of a motor on the mechanical device and output a corresponding rotation speed detection signal. Optionally, the number of rotation speed sensors 20 can be multiple, which are configured to detect rotation speeds of different motors of the mechanical device, or are configured to detect a rotation speed of a same motor of the mechanical device, so that the gateway component 10 can more accurately confirm the rotation speed of the motor according to feedback results of the multiple rotation speed sensors 20.

[0057] Optionally, the vibration and temperature sensor 32 can be implemented by a temperature and vibration integrated sensor, which can simultaneously detect vibration data and temperature data of a certain position of the mechanical device and then output corresponding vibration detection signals and temperature detection signals.

[0058] Optionally, in an embodiment, the vibration and temperature acquisition box 31 can be implemented by using an interface, a controller and a wireless communication circuit 312. The controller can be implemented by using, for example, an MCU (Microcontroller Unit), a DSP (Digital Signal Process), an FPGA (Field Programmable Gate Array), an SOC (System On Chip), etc. The wireless communication circuit 312 can be implemented by using a star flash communication circuit to reduce wireless communication power consumption and improve wireless communication quality. The controller in the vibration and temperature acquisition box 31 establishes an electrical connection path with the vibration and temperature sensor 32 through the interface and the cable to realize data intercommunication. The controller can establish a communication connection with the gateway component 10 through the wireless communication circuit 312. Thus, since the vibration and temperature sensor 32 is separately arranged in the present application instead of being integrated with the data processing communication part as in the prior art, the vibration and temperature sensor 32 with a smaller size can detect the vibration and temperature of a narrow space in a mechanical equipment and output the results to the external acquisition box through the cable, and then the acquisition box transmits the results to the gateway component 10 wirelessly, thereby meeting the requirements of transmitting the sensor detection data wirelessly and detecting the state data of the narrow space in the mechanical equipment at the same time.

[0059] In addition, the vibration and temperature acquisition box 31 can also establish a wireless communication connection with a user's handheld terminal, such as a user's mobile phone, through another communication module in the vibration and temperature acquisition box 31, so that the user can perform point inspection on multiple vibration and temperature acquisition boxes 31 and obtain the data output by the vibration and temperature sensors 32 connected to the vibration and temperature acquisition boxes 31 through the handheld terminal.

[0060] Optionally, referring to Figure 3 In an embodiment, the gateway component 10 includes a star flash gateway component 10; the star flash gateway component 10 includes:

[0061] a second control circuit 11;

[0062] a rotation speed signal acquisition circuit 12, an input end of the rotation speed signal acquisition circuit 12 is connected with the rotation speed sensor 20, and an output end of the rotation speed signal acquisition circuit 12 is electrically connected with the second control circuit 11; the rotation speed signal acquisition circuit 12 is used for processing the rotation speed detection signal and outputting the processed rotation speed detection signal to the second control circuit 11;

[0063] a star flash communication module 13, the second control circuit 11 is electrically connected with the star flash communication module 13, and the star flash communication module 13 is used for establishing a wireless communication connection with the vibration and temperature detection component 30;

[0064] The second communication module 14 is electrically connected with the second control circuit 11, and is used for communication connection with an external terminal.

[0065] In the embodiment, the second control circuit 11 can be implemented by a main controller such as an MCU (Microcontroller Unit), a DSP (Digital Signal Process), an FPGA (Field Programmable Gate Array), an SOC (System On Chip), etc., for example, a Zynq-7000 All Programmable SoC chip.

[0066] The rotation speed signal acquisition circuit 12 can include a signal connection end for accessing the rotation speed sensor 20, an optical coupler and a signal conditioning circuit. The optical coupler is used to output the rotation speed detection signal output by the rotation speed sensor 20 to the signal conditioning circuit through voltage isolation. The signal conditioning circuit is used to output the signal output by the optical coupler after filtering, gain and buffering processing.

[0067] The second communication module 14 can include a wired communication module and a wireless communication module. The wired communication module can be implemented by a CAN communication module, an RS485 communication module, an RJ45 communication module, etc. The wireless communication module can be implemented by a 4G / 5G communication module, a local area network communication module, etc. The second control circuit 11 can establish a communication connection with an external terminal through the second communication module 14 to receive data from the external terminal and upload data to the external terminal.

[0068] The star flash communication module 13 can be implemented by a Hi3863V100 star flash SOC of HiSilicon. The Hi3863V100 star flash SOC supports SLE 1MHz / 2MHz / 4MHz bandwidth, SLE1.0 protocol, supports SLE gateway function, maximum air interface rate 12Mbps, has ultra-low air interface delay, strong anti-interference ability and low power consumption.

[0069] Specifically, the second control circuit 11 in the gateway component 10 determines the rotating speed of the motor of the mechanical equipment when receiving the rotating speed detection signal processed by the rotating speed signal acquisition circuit 12, and sends a vibration trigger detection signal to at least one vibration temperature acquisition box 31 through the star flash communication module 13 when the rotating speed switches from uniform speed to non-uniform speed, so that the vibration temperature detection box transmits the vibration detection signal from the current vibration temperature sensor 32 or controls the vibration temperature detection box to start the vibration detection function of the vibration temperature sensor 32 and transmits the vibration detection signal from the current vibration temperature sensor 32 back to the star flash communication module 13, which is then output to the second control circuit 11 for processing. It can be understood that in the prior art, vibration detection is often intermittent, but for mechanical equipment, vibration data detection is not very critical in the uniform speed state of the motor (because in the uniform speed state, vibration data can also be calculated by other detection methods), but when the motor switches from uniform speed to variable speed, a special vibration sensor is needed to detect the data. However, since the vibration sensor detection is intermittent, there may be a delay in the vibration data, which makes it difficult to ensure the accuracy of the vibration data. Therefore, through the above arrangement, the gateway component 10 will trigger the vibration temperature acquisition box 31 to collect the current vibration data through the vibration temperature sensor 32 when it is determined that the rotating speed of the motor has switched from uniform speed to non-uniform speed according to the result of the rotating speed sensor 20, thereby effectively ensuring the accuracy of vibration data collection.

[0070] Meanwhile, the second control circuit 11 will also upload the multiple temperature detection signals, multiple vibration detection signals and at least one rotating speed signal obtained by the multiple vibration temperature acquisition boxes 31 and at least one rotating speed sensor 20 to an external terminal, such as a cloud server, a manufacturer's background, a system terminal, etc. through the second communication module 14, for data analysis by the external terminal and for users to check on the external terminal.
