As sensor technology evolves, more and more sensors are used. But the sensor technology is single in function. In the case of acquiring multiple data, a mode of setting multiple sensors is generally adopted or mathematical analysis is performed on the data acquired by one sensor to acquire multiple data. According to the invention, the circuit structure is designed to fuse various sensing components onto one sensing terminal, so that under the condition that various data needs to be acquired, the acquisition of various data can be realized by only arranging one sensing terminal, and the vibration, the track, the gesture and the like of an object are analyzed. The fused multi-sensing assembly of the present invention may include a first acceleration sensing assembly, an inertial measurement sensing assembly, and a tilt sensing assembly. Each sensing component is connected with the processing module, when the detected equipment generates data, such as equipment vibration is detected, the vibration sensor generates a signal to inform the processing module, and the processing module wakes the corresponding sensor to collect data and sends the collected data to the computing terminal for object motion analysis.

Example 1

In this embodiment, the general object motion analysis system based on the intelligent motion sensing terminal provided by the invention may be a mechanical fault diagnosis and predictive maintenance system. The general object motion analysis system provided by the invention collects the high-frequency vibration acceleration data of the target object through the sensing terminal 100. The sensing terminal 100 transmits the acquired data to the computing terminal 200 for processing. The computing terminal 200 obtains the characteristic results of the effective vibration speed, the effective vibration amplitude, the vibration spectrum and the like of the target object through the computing and analyzing the data acquired by the sensing terminal 100.

The mechanical fault diagnosis and predictive maintenance system provided in the present embodiment at least includes a sensing terminal 100, a computing terminal 200, and a cloud server 300. The sensing terminal 100 performs data acquisition on the target object. The computing terminal 200 receives the data collected by the sensing terminal 100 and performs a computing analysis on the data collected by the sensing terminal 100. After the calculation terminal 200 completes the calculation analysis, the calculation analysis result is sent to the cloud server 300. The cloud server 300 performs corresponding management and control in response to the calculation analysis result of the calculation terminal 200. Referring to fig. 1, the computing terminal 200 establishes data connection with the cloud server 300 and at least one sensing terminal 100, respectively. Preferably, the computing terminal 200 may be connected to more than two sensing terminals 100 at the same time. The computing terminal 200 obtains a motion characteristic result of the target object by performing computation and analysis on the data acquired by the sensing terminal 100. The motion characteristic results comprise effective vibration speed, effective vibration amplitude, vibration frequency spectrum and the like.

For example, when the environmental wind force of a generator set for generating electricity in a wind farm is too large, abnormal vibration can be generated by the wind generator set, and the mechanical fault diagnosis and predictive maintenance system of the embodiment can be used for inspection work of the wind farm.

The sensing terminal 100 of the present embodiment may be provided with a processing module 110, a first acceleration sensing component 120, and a second acceleration sensing component 160. The first acceleration sensing component 120 and the second acceleration sensing component 160 of the sensing terminal 100 may collect vibration data of a target object (e.g., a wind turbine blade). Since the material properties of the generator set device may be affected by temperature, for example, the connection portion of the fan blade and the rotating shaft of the generator set may generate heat due to rotational friction, the temperature sensing terminal 100 is further provided with a temperature sensing assembly 130 for excluding the temperature factor.

Preferably, in order to enable data acquisition under different usage environments, the sensing terminal 100 of the present embodiment is provided with two models of a wired sensing terminal 101 as shown in fig. 2 and a wireless sensing terminal 102 as shown in fig. 3. The wired sensing terminal 101 can transmit the collected data through a data line connected to the communication port 220. Preferably, the communication ports 220 include a high-speed communication port 221 and a low-speed communication port 222. The wireless sensing terminal 102 can transmit the acquired data to the computing terminal 200 for computational analysis in a wireless transmission manner through the configured first Lora communication unit 170. The universal object motion analysis system of the present invention may be configured with two kinds of sensing terminals 100 to satisfy object motion analysis under different use environments.

The sensing components transmit the collected data to the processing module 110 for processing through the communication protocol interface. Preferably, the second acceleration sensing assembly 160 includes at least a second acceleration sensor 161, a filter 162, a voltage follower 163, and a high-speed ADC164. The data of the alternating current single axis direction collected by the second acceleration sensor 161 is required to be transmitted to the processing module 110 for processing through the communication protocol interface after passing through the filter 162, the voltage follower 163 and the high-speed ADC164 in sequence. Preferably, the first acceleration sensing assembly 120 may include a first acceleration sensor. Preferably, the processing module 110 includes a processing chip 111, a random access memory 112, and a read only memory 113. The processing chip 111 is electrically connected to the random access memory 112 and the read only memory, respectively.

The computing terminal 200 of the embodiment receives the vibration data of the target object collected by the sensing terminal 100, performs calculation and analysis based on the vibration data to obtain analysis results such as a vibration speed, a vibration amplitude, a vibration spectrum, and the like, and transmits the analysis results to the cloud server to realize supervision of the target object.

Referring to fig. 4, the computing terminal 200 includes a computation analysis module 210, a communication port 220, a second Lora communication unit, and a 4G communication unit. The communication port 220, the second Lora communication unit, and the 4G communication unit are electrically connected to the computational analysis module 210, respectively. The computing terminal 200 receives data collected by the sensing terminal 100 through the configured second Lora communication unit 230 or the communication port 220. The second Lora communication unit 230 or the communication port 220 transmits the received data to the calculation and analysis module 210 for calculation and analysis. The calculation and analysis module 210 performs calculation and analysis through a preset program in response to the received data to obtain an analysis result of the motion state parameters including at least vibration speed, vibration amplitude, vibration spectrum and the like. The calculation analysis module 210 transmits the analysis result to the 4G communication unit 240 and transmits the analysis result to the cloud server 300 through the 4G communication network. In other words, the computing terminal 200 establishes communication with the cloud server 300 using the configured 4G communication unit 240, and uploads the calculation analysis result generated after the calculation analysis of the data collected by the sensing terminal 100 and received by the computing terminal 200 through the configured second Lora communication unit 230 or the communication port 220 to the cloud server 300. The sensing terminal 100 performs data acquisition on the target object and then transmits the acquired data to the computing terminal 200 through a wired or wireless data transmission mode. The computing terminal 200 performs analysis of the movement of the object by performing computational analysis on the data collected by the sensing terminal 100. The computing terminal 200 transmits the analysis result of the object motion to the cloud server 300 by means of the configured 4G communication unit 240. Preferably, the communication ports 220 include a high-speed communication port 221 and a low-speed communication port 222. Preferably, the high-speed communication port 221 may be an IEEE 1588PoE high-speed interface. Preferably, the low speed communication port 222 may be an RS485 low speed interface.

Preferably, the sensing terminal 100 preferably employs the wired sensing terminal 101 in an environment suitable for wired power supply without considering power consumption and having real-time requirements for data. The wired sensing terminal 101 can be connected with the wired sensing terminal 101 through the communication port 220 in a wired way, and data of the wired sensing terminal 101 are received for calculation and analysis, so that real-time performance of object motion analysis is guaranteed. Preferably, the wired sensing terminal 101 establishes a real-time data connection with the computing terminal 200 through the communication port 220 in a wired connection manner to the computing terminal 200, so as to directly transmit the collected data to the computing terminal 200 in real time for computational analysis.

Preferably, the wireless sensor terminals 102 are employed where data real-time requirements are low and where a large number of sensors are required to be deployed. Preferably, the wireless sensor terminal 102 model of the sensor terminal 100 can directly establish wireless communication with the second Lora communication unit 230 configured by the computing terminal 200 through the configured first Lora communication unit 170, so as to directly transmit the acquired data to the computing terminal 200 for computational analysis. Preferably, in a use environment where the sensor terminal 100 needs to be deployed in a large area and it is inconvenient to deploy a data transmission line, the wireless sensor terminal 102 may transmit data required for object motion analysis to the computing terminal 200 using the configured second Lora communication unit 230.

Preferably, in a use environment requiring that a plurality of sensing terminals 100 collect data synchronously and with low power consumption, the deployment of the system of the embodiment may be to connect at least one wired sensor 101 to the repeater 400 through the communication port 220, and then the repeater 400 establishes wireless communication with the second Lora communication unit 230 configured by the computing terminal 200 through the configured third Lora communication unit 410 so as to send the data collected by the wired sensor 101 to the computing terminal 200 for computational analysis. Preferably, two or more of the wired sensing terminals 101 are wired to the repeater 400 through the communication port 220. The repeater 400 establishes wireless communication with the second Lora communication unit 230 configured by the computing terminal 200 through the configured third Lora communication unit 410. The repeater 400 receives data collected by the plurality of wired sensing terminals 101 in a wired communication manner, and then transmits the received data to the computing terminal 200 in a wireless communication manner for computational analysis, thereby ensuring the synchronicity of the plurality of sensing terminals 100. And because the power consumption of the repeater 400 is lower than that of the computing terminal 200, and the Lora communication unit in the system can be selectively turned on (started when data transmission is required and dormant when data transmission is not required). Compared with the mode that the computing terminal 200 continuously opens the communication port 220 to receive the data collected by the wired sensing terminal 101, the data transmission mode of the repeater 400 can reduce the power consumption of the system. Referring to fig. 5, the repeater 400 is provided with a third Lora communication unit 410 and a low-speed communication port 222. The reason why only the low-speed communication port 222 is provided is that the communication speed of the repeater 400 at the time of the Lora communication is significantly lower than that of the wired communication, and the high-speed communication requirement is not satisfied, and thus the repeater 400 is not provided with the high-speed communication port 221.

The first acceleration sensing component 120 and the second acceleration sensing component 160 are arranged on the same plate body in a manner of being axially flush with each other so that collected data are aligned, so that the processing module 110 is convenient for processing the data collected by the first acceleration sensing component 120 and the second acceleration sensing component 160. Specifically, referring to fig. 5, the first acceleration sensor of the first acceleration sensing assembly 120 and the second acceleration sensor 161 of the second acceleration sensing assembly 160 are disposed on the same board in an axially aligned manner. Preferably, after the first acceleration sensing component 120 and the second acceleration sensing component 160 are disposed on the same board body in an axis alignment manner, at least one reference parameter of the first acceleration sensing component 120 and the second acceleration sensing component 160 is the same when data acquisition is performed, so that the processing module 110 of the terminal 100 can perform fusion processing on data from different sensing components. Preferably, the core devices of both the first acceleration sensing assembly 120 and the second acceleration sensing assembly 160 include accelerometers. The sensing terminal 100 of the embodiment may set a plurality of sensing components with accelerometer as core devices on a board body with the same circuit structure in an axis alignment manner, so that at least one parameter (such as a position height, a relative coordinate, etc.) of the mass sensing components is the same, thereby reducing parameters required to be processed when the processing module 110 of the sensing terminal 100 and the computing terminal 200 fuse data acquired by the mass sensing components, realizing rapidness, and indirectly reducing time spent by the processing when performing object motion analysis. Preferably, the first acceleration sensing assembly 120 and the second acceleration sensing assembly 160 are disposed on the plate body at positions remote from the surrounding mechanical mounting holes, so as to avoid external stress from being transferred to the sensor. The sensing terminal 100 of the embodiment centers each sensing component on the circuit board inwards, so as to avoid inaccurate data acquisition results of the sensing components caused by the fact that stress generated by the circuit board is transferred to the sensing components placed on the circuit board due to the fact that the sensing terminal 100 is packaged.

Preferably, the processing module 110 receives the data sent by the sensing component through the interface, thereby processing the received data. Fig. 7 is a schematic diagram of a processing chip circuit of the processing module 110. Preferably, the processing chip 111 may be an STM32F446ZET6. Fig. 8 is a schematic circuit diagram of a preferred ram 112 of the sensing terminal 100 of the present invention. Preferably, the random access memory is a RAM chip including at least SDRAM and PSRAM. Preferably, the random access memory 112 may be an SDRAM. Preferably, the processing module 110 integrates a 2Mbytes high capacity SDRAM chip. Preferably, the SDRAM power supply is controllable, and the power consumption of the system is reduced when data are not collected. When the waveform data needs to be collected, a large-capacity storage unit is required to store the waveform data, and the processing module 110 turns on the power switch of the large-capacity PSRAM chip. Fig. 9 is a schematic circuit diagram of a preferred rom 113 of the terminal 100 of the present invention. Preferably, the read only memory 113 may be a FLASH. Preferably, the read only memory 113 is connected to the processing module 110 through an interface. Preferably, the interface may be an SPI interface and/or an I/O interface. Preferably, the power supply of the read only memory 113 can be controlled by a signal. Without using the rom 113, the sensing terminal 100 can cut off the power supply of the rom 113.

The processing module 110 has at least a first state and a second state different from the first state. The first acceleration sensing component 120 is capable of controlling the activation/deactivation of the second acceleration sensing component 160 by controlling the switching of the first state and the second state of the processing module 110. In particular, for the wireless sensor terminal 101, the first acceleration sensing component 120 is further capable of controlling the activation/dormancy of the Lora communication unit 170 by controlling the switching of the first state and the second state of the processing module 110. In an actual deployment, to reduce the power consumption of the sensing terminal 100 during use, the second acceleration sensing component 160 and/or the Lora communication unit 170 are/is in a sleep state by default, the processing module 110 is in a first state in which only a part of the components are in operation, and the first acceleration sensing component 120 is in a normal operation state. The processing module 110 may enter the second state from the first state if and only if the data acquired by the first acceleration sensing component 120 is abnormal. The processing module 110 entering the second state uses a preset program to collect data from the first acceleration sensing component 120 and determines whether to turn on the second acceleration sensing component 160 and/or the Lora communication unit 170. When no abnormality occurs in the data collected by the first acceleration sensing assembly 120, a large number of components of the sensing terminal 100 (such as the second acceleration sensing assembly 160 and the Lora communication unit 170) are in a sleep state, so that the sensing terminal 100 can perform low-power-consumption data collection.

Preferably, the processing module 110 is capable of implementing on-off control of the power supply of the random access memory 112 and the read only memory 113 through switching of the first state and the second state. Preferably, when the power supplies of the ram 112 and the rom 113 are turned on, the processing module 110 can process and transmit the data collected by the sensing assembly with the highest performance, so as to facilitate the calculation and analysis of the object motion by the subsequent computing terminal 200. The processing chip 111 is electrically connected to the random access memory 112 and the read only memory, respectively. The processing chip 111 signals the random access memory 112 and the read only memory 113 to be powered on if and only if the processing module 110 is in the second state. When the processing module 110 is in the first state, the processing chip 111 cuts off the power supply of the random access memory 112 and the read-only memory 113 through the electric signal to enable the random access memory 112 and the read-only memory 113 to sleep, so that the power consumption of the whole terminal 100 is high due to the fact that the random access memory 112 and the read-only memory 113 generate power consumption under the non-working condition. Preferably, the first state of the processing module 110 is a sleep state, and the second state of the processing module 110 is an operating state. The processing module 110 may control the power supply of the first acceleration sensing assembly 120, the second acceleration sensing assembly 160, and/or the Lora communication unit 170 through an interface. When the processing module 110 is in the first state, in order to reduce the power consumption of the terminal 100, the processing module 110 sends a signal through the interface to cut off the power supply of the second acceleration sensing component 160 and/or the Lora communication unit 170 so that the second acceleration sensing component 160 and/or the Lora communication unit 170 goes to sleep. When the second acceleration sensing component 160 and/or the Lora communication unit 170 are dormant, the processing module 110 can send a signal through the interface to conduct power supply of the first acceleration sensing component 120, so that the first acceleration sensing component 120 can work normally and stably, and power consumption of the terminal can be reduced under the condition that data acquisition is met. Preferably, in the case that the processing module 110 is in the first state, the processing module 110 can disconnect the power supply of the second acceleration sensing assembly 160 and the Lora communication unit 170, and turn on the power supply of the first acceleration sensing assembly 120, so that the sensing terminal 100 can operate with the lowest power consumption.

Fig. 10 is a schematic circuit diagram of a preferred first acceleration sensing assembly 120. Preferably, the MEMS high-frequency acceleration sensor employs a high-frequency acceleration sensor KX132. The sensor is specially designed for high-frequency vibration analysis, the output frequency of the sensor is up to 25.6KHz, the output bandwidth is up to 8.2KHz, and compared with the traditional acceleration sensor, the high-frequency acceleration sensor used by the sensor has better high-frequency vibration measurement effect and higher accuracy of analyzing the vibration frequency through the acceleration signal of the sensor. Preferably, the first and second

After the processing module 110 of the sensing terminal 100 integrated with the various sensing components is awakened by the first acceleration sensing component 120, a preset program can be run to supply power to the second acceleration sensing component 160 through the I/O port of the second acceleration sensing component 160, so that the second acceleration sensing component 160 is started to enable the second acceleration sensing component 160 to acquire data. As shown in fig. 5, the power supply of the first acceleration sensing assembly 120 may be controlled by a signal. Preferably, the processing module 110 is capable of switching on or off the power supply of the first acceleration sensing assembly 120 by sending a signal through the interface. A technician deploying the terminal 100 sets a corresponding response threshold for the first acceleration sensing component 120 by analyzing the data that needs to be sensed in the field. Preferably, in the case that the data collected by the first acceleration sensing component 120 exceeds a preset threshold, the first acceleration sensing component 120 generates an interrupt signal, and transmits the interrupt signal to the processing module 110 through an interface connected with the processing module 110, thereby waking up the processing module 110. The processing module 110 enters the second state from the first state after receiving the interrupt signal to wake up. Preferably, when the data collected by the first acceleration sensing component 120 exceeds the preset threshold, that is, the collected data is considered to be abnormal, the processing module 110 needs to be requested to determine the abnormality, so that the processing module 110 generates an interrupt signal and transmits the interrupt signal to the processing module 110 through an interface connected with the processing module 110. The processing module 110 responds to the receipt of the interrupt signal to enter a second state with higher power consumption for all devices to operate from a first state with lower power consumption in which part of the devices are dormant, and analyzes the data collected by the first acceleration sensing component 120. Preferably, the terminal 100 only makes the processing module 110 enter the second working state with higher power consumption when the data collected by the first acceleration sensing component 120 needs to be analyzed, and the processing module 110 is in the first working state with lower power consumption when the data collected by the first acceleration sensing component 120 does not need to be analyzed, so that the processing module 110 is prevented from being in the second working state with higher power consumption all the time when the terminal 100 performs long-term data collection, and further the power consumption when the terminal 100 performs data collection is reduced.

Preferably, the temperature sensing assembly 130 configured by the sensing terminal 100 is connected with the processing module 110 through an interface.

Preferably, the MEMS temperature sensor employs DS18B20. In the case where the temperature sensing assembly 130 is not required, the power supply of the temperature sensing assembly 130 is turned off, thereby reducing the system power consumption.

Preferably, the processing module 110 is capable of controlling the power mode of the temperature sensing assembly 130 by sending signals through the interface. Preferably, the processing module 110 is capable of shutting off power to the temperature sensing assembly 130 without sensing temperature, reducing system power consumption. Preferably, a technician deploying the terminal may set the manner in which the temperature sensing assembly 130 operates based upon analysis of the target object. Preferably, the temperature sensing assembly 130 may operate in such a manner that the processing module 110 sends a signal to make the temperature sensing assembly 130 normally supply power after entering the second state, so that the temperature sensing assembly 130 starts to operate to perform data collection.

The second acceleration sensor 161 outputs an analog signal, which is sampled by the filter 162, the voltage follower 163, and the high-speed ADC164, and then outputs the analog signal to the processing module 110 for processing. Referring to fig. 12, after the processing module 110 makes the second acceleration sensor operate by powering on the second acceleration sensor through the second acceleration sensor power control circuit 165, the second acceleration sensor 161 samples the voltage signal of the second acceleration sensor 161 through the high-speed ADC164 after passing through the filter 162 and the voltage follower 163, and then is connected to the processing module 110 through the SPI bus, so as to collect the voltage signal of the second acceleration sensor 161, and the second acceleration sensing component 160 is highly integrated. Preferably, the second acceleration sensor 161 may be an ADXL100X series MEMS-IEPE chip. Preferably, the filter 162 may be a band-limited filter.

The ADXL100X chip has the lowest noise at a supply voltage of 5V. In order to improve the accuracy of data acquisition of the second acceleration sensing component 160, the present embodiment controls the power supply of the ADXL100X through the second acceleration sensor power control circuit 165. Fig. 13 is a schematic diagram of a preferred second acceleration sensor power control circuit of the terminal of the present invention. And the rear stage of the MEMS-IEPE chip is connected with a band-limited filter, so that the accuracy of the high-frequency response of the sensor is improved. The high speed ADC164 unit supplies 3V3. The band-limited filter circuit divides the output of the amplifier through a resistor and outputs the voltage to the voltage follower so that the 5V signal is linearly reduced to a 3V3 range, and after the voltage follower 163, the impedance of the MEMS-IEPE chip signal is reduced so that the high-speed ADC164 is more accurately sampled. Referring to fig. 13, the processing module 110 preferably cuts off the power supply to the first acceleration sensing assembly 120 by sending a signal through the interface in case of enabling the second acceleration sensing assembly 160. Preferably, the frequency of the data that can be acquired by the second acceleration sensing assembly 160 is higher than the frequency of the data that can be acquired by the first acceleration sensing assembly 120.

Preferably, the interface may be an SPI interface and/or an I/O interface. Preferably, the processing module 110 processes the data collected by the first acceleration sensing component 120 and/or the second acceleration sensing component 160 and then transmits the processed data to the computing terminal 200 through the first Lora communication unit 170.

After the first Lora communication unit 170 completes data transmission, the processing module 110 turns off the power of the first Lora communication unit 170, so that the first Lora communication unit 170 goes to sleep. The sensing terminal 100 of the embodiment starts the first Lora communication unit 170 when data needs to be sent to the computing terminal 200, and makes the first Lora communication unit 170 enter sleep at other moments, so that power consumption waste caused by continuous starting of the first Lora communication unit 170 is avoided, power consumption of the sensing terminal 100 when data is acquired is reduced, and power consumption of the mechanical fault diagnosis and predictive maintenance system provided by the embodiment is further reduced.

Preferably, the interface may be an interface supporting the SPI communication protocol. FIG. 7 is a schematic circuit diagram of a preferred inertial measurement sensing assembly. Preferably, the inertial measurement sensing assembly 140 may be a MEMS inertial measurement sensor. Preferably, the MEMS inertial measurement sensor employs a 6-axis sensor BMI085. The 6-axis sensor integrates acceleration and angular velocity sensors, and acceleration noise is lower than that of the sensor

Angular velocity noise is lower than->

According to the invention, the motion trail of the object is independently analyzed by using the 6-axis sensor, the axial directions of the angular velocity and the acceleration are calibrated when the chip leaves the factory, and the analysis accuracy of the motion trail is higher. As shown in fig. 7, the power supply of the inertial measurement sensing assembly 140 can be controlled by a signal. In actual use, the processing module 110 can be based onWhether or not inertial analysis is required to determine whether or not the inertial measurement sensing assembly 140 is powered, thereby reducing system power consumption. Preferably, the processing module 110 is capable of sending a signal through the interface to put the inertial measurement sensing assembly 140 into a sleep or powered down state. Preferably, the processing module 110 is capable of powering down the inertial measurement sensing assembly 140 without the use of the sensing assembly, reducing system power consumption.

As shown in fig. 17, the power supply of the tilt sensing assembly 150 may be controlled by a signal. The processing module 110 can turn off the power supply of the tilt sensing assembly 150 without performing gesture analysis, thereby reducing system power consumption. In the case where gesture analysis is required, the processing module 110 can turn on power supply of the tilt sensing assembly 150, so that the terminal can sense tilt data. The processing module 110 sends a signal to enable the inclination angle sensing assembly 150 to supply power normally, and the inclination angle sensing assembly 150 starts to work for data acquisition. The tilt angle sensing component 150 sends the collected data to the processing module 110 through the SPI or other IO port, and the processing module 110 transmits the data to the computing terminal 200 for computation and analysis through a wired or wireless communication mode.

When the threshold value acquired by the first acceleration sensing component 120 is lower than the first threshold value, the first acceleration sensing component 120 does not generate an interrupt signal to switch the first state of the processing module 110 to the second state. When the threshold value acquired by the first acceleration sensing component 120 is higher than the first threshold value and lower than the second threshold value, the first acceleration sensing component 120 can accurately acquire data, but the processing module 110 is required to process the acquired data, and the processing module 110 does not need to start the second acceleration sensing component 160. When the threshold value of the first acceleration sensing component 120 is higher than the second threshold value, the first acceleration sensing component 120 cannot accurately collect the data, and the processing module 110 needs to start the second acceleration sensing component 160 to collect the data. The combined use of the first acceleration sensing component 120 and the second acceleration sensing component 160 can achieve data acquisition in a wider range than that of a single acceleration sensing component, but the simultaneous use of the first acceleration sensing component 120 and the second acceleration sensing component 160 can generate higher power consumption, and the power consumption of the terminal 100 can be reduced while achieving data acquisition in a wide range by the mode of calling the acceleration sensing components in a grading manner.

The second acceleration sensing assembly 160 is in an operating state when the processing module 110 is in the second state. The processing module 110 is in the first state to collect data required for object motion analysis through the first acceleration sensing assembly 120. The processing module 110 is in the second state to collect data required for object motion analysis via the second acceleration sensing assembly 160.

Preferably, the inertial measurement sensing assembly 140 may work in such a manner that the processing module 110 enters the second state in response to the interrupt generated by the first acceleration sensing assembly 120, and after the processing module 110 enters the second state, a signal is sent to enable the inertial measurement sensing assembly 140 to supply power normally, so that the inertial measurement sensing assembly 140 starts to work to collect data and sends the collected data to the processing module 110 for processing through an interface.

Example 3

This embodiment is a further improvement of embodiment 1 and embodiment 2, and the repeated description is omitted. In this embodiment, the universal object motion analysis system based on the intelligent motion sensing terminal provided by the invention can be a marine disaster monitoring and early warning system. The marine disaster monitoring and early warning system provided in this embodiment is composed of a sensing terminal 100, a computing terminal 200 and a cloud server 300. The sensing terminal 100 of the general object motion analysis system has a track data acquisition function, and the general object motion analysis system can be applied to the field of marine disaster monitoring and early warning by acquiring marine wave height data, the computing terminal 200 calculates and analyzes 1/3 wave height, 1/10 wave height and other data based on the data acquired by the sensing terminal 100, and the data exceeding an early warning value is uploaded to the cloud server 300, so that the marine disaster monitoring and early warning function is realized.

In the field of marine disaster monitoring and early warning, disaster monitoring and early warning are generally performed by monitoring ocean wave height. Traditional mode of monitoring ocean wave height needs to be deployed the seabed with water pressure sensor, installs check out test set on the buoy, calculates the surface of water height in order to realize the monitoring of ocean wave height through measuring water pressure sensor's pressure. The traditional mode has long construction period, and the water pressure sensor has higher cost, so that the water pressure sensor is inconvenient for large-scale deployment. The marine disaster monitoring and early warning system of the embodiment uses the integrated motion sensing terminal 100 to collect track data of the buoy, analyzes the moving track of the buoy through the computing terminal 200, calculates the height of the marine wave, and uploads the calculation and analysis result to the cloud server 300 by the computing terminal 200 to realize marine disaster and early warning. Compared with the traditional monitoring and early warning scheme based on the water pressure sensor, the system has lower cost and is convenient for large-scale deployment.

The sensing terminal 100 used in the marine disaster monitoring and early warning system at least comprises a sensing assembly and a processing module 110. Preferably, the sensing terminal 100 incorporates at least two sensing components, namely a first acceleration sensing component 120 and an inertial measurement sensing component 140. The first acceleration sensing assembly 120 and the inertial measurement sensing assembly 140 are respectively connected with the processing module 110 of the sensing terminal 100 through interfaces. The processing module 110 has at least a first state and a second state different from the first state. The first acceleration sensing component 120 is capable of controlling the activation or dormancy of the inertial measurement sensing component 140 by controlling the switching of the first state and the second state of the processing module 110.

The first state of the processing module 110 is a sleep state and the second state is an active state. The sensing terminal 100 employed by the marine disaster monitoring and early warning system is further provided with a first Lora communication unit 170. Preferably, the sensing terminal 100 used by the marine disaster monitoring and early warning system is a wireless sensing terminal 102. The first Lora communication unit 170 is connected with the processing module 110 through an interface. The processing module 110 can transmit data to the first Lora communication unit 170 through an interface. The processing module 110 may also control the power supply of the first Lora communication unit 170 through an interface. The first acceleration sensing component 120 is capable of indirectly controlling the enabling or disabling of the first Lora communication unit 170 by controlling the switching of the first state and the second state of the processing module 110.

Preferably, in the actual deployment, in the initial state, the processing module 110 is in the first state, and the first acceleration sensing component 120 is powered normally through the interface. The processing module 110 in the first state cuts off the power supply to the inertial measurement sensing assembly 140 and the first Lora communication unit 170 through the interface, so that the inertial measurement sensing assembly 140 and the first Lora communication unit 170 enter the sleep state.

Preferably, the first acceleration sensing assembly 120 is provided with a threshold value. In the event that the acquired data exceeds a threshold, the first acceleration sensing component 120 generates a wake-up signal and sends the "wake-up signal" to the processing module 110 via the interface. The processing module 110 switches from the first state to the second state in response to receipt of the wake-up signal. Preferably, the wake-up signal generated by the first acceleration sensing component 120 may be an interrupt signal. The processing module 110 entering the second state turns on the power supply of the inertial measurement sensing assembly 140 through the interface, so that the inertial measurement sensing assembly 140 can acquire track data. Preferably, the track data collected by the inertial measurement sensing component 140 is processed by the processing module 110 and then sent to the computing terminal 200 for computational analysis through the first Lora communication unit 170. Preferably, the processing module 110 in the second state turns on the power supply of the first Lora communication unit 170 through the interface when it is required to transmit the trajectory data collected by the inertial measurement sensing assembly 140 to the computing terminal 200, so that the sensing terminal 100 can perform the Lora communication with the computing terminal 200 to transmit the trajectory data collected by the sensing terminal 100. Preferably, when the sensing terminal 100 does not need to transmit data to the computing terminal 200, the processing module 110 cuts off the power supply of the first Lora communication unit 170 through the interface, so that the system power consumption is reduced, and the power consumption waste caused by the electrified operation of the first Lora communication unit 170 when the data transmission is not needed is avoided. Preferably, the data collected by the first acceleration sensing component 120 is only used as a trigger signal for controlling the working state of the processing module 110, and is not used as a basis for performing calculation and analysis by the computing terminal 200, and transmission is not required. Preferably, when the data collected by the first acceleration sensing component 120 is below a preset threshold, the first acceleration sensing component 120 generates a sleep signal and sends the sleep signal to the processing module 110 through the interface.

Preferably, the processing module 110 enters the first state of lower power consumption from the second state of higher power consumption in response to the receipt of the sleep signal. Preferably, the first acceleration sensing assembly 120 remains active regardless of whether the processing module 110 is in the first state or the second state.

In practical use, the sensing terminal 100 of the universal object motion analysis system provided by the invention can collect various data on one sensing terminal 100 by integrating various sensing components, so that the system can analyze the motion of objects such as vibration, track, gesture and the like. In this embodiment, the universal object motion analysis system based on the intelligent motion sensing terminal provided by the invention can be a geological disaster monitoring and early warning system. In the geological disaster monitoring and early warning field, the universal object motion analysis system of the invention utilizes the sensing terminal 100 to collect track data and vibration data of rock or soil, calculates and analyzes risk data such as vibration amplitude, sliding amplitude and the like of the rock or soil through the computing terminal 200, and uploads technical analysis results to the cloud server 300 to realize monitoring and early warning of geological disasters such as debris flow, collapse, landslide and the like, thereby realizing digital upgrading of disaster monitoring.

The geological disaster monitoring and early warning system provided in this embodiment at least includes a sensing terminal 100, a computing terminal 200 and a cloud server 300. The sensing terminal 100 is provided with at least a first acceleration sensing assembly 120 and an inertial measurement sensing assembly 140. The traditional geological disaster monitoring scheme is that a pull wire sensor is inserted into the rock or soil to be detected, a proper position is selected for stretching the sensor, data acquired by the sensor are subjected to signal mediation and then are calculated and analyzed, and finally the data are uploaded to a cloud platform. The geological disaster monitoring and early warning system provided by the embodiment can directly measure rock or soil sliding data of a single point through the sensing terminal 100, then the sensing terminal 100 sends the data to the computing terminal 200 for analysis and calculation through a wired mode and a wireless mode, and the computing terminal 200 uploads a calculation analysis result to the cloud server 300 to realize monitoring and early warning.

Preferably, the sensing terminal 100 may include a processing module 110, a first acceleration sensing assembly 120, an inertial measurement sensing assembly 140, and an inclination sensing assembly 150. Preferably, the first acceleration sensing assembly 120 is capable of accurately detecting vibration data having a frequency within 10 KHz. The vibration frequency of various geological disasters can fall into the detection range of the first acceleration sensing component 120, so the sensing terminal 100 of the geological disaster monitoring and early warning system provided in this embodiment is the second acceleration sensing component 160 with the detection frequency greater than 10 KHz.

Preferably, the first acceleration sensing assembly 120, the inertial measurement sensing assembly 140 and the tilt sensing assembly 150 are respectively connected with the processing module 110 through interfaces. The processing module 110 is capable of controlling the power supply of the first acceleration sensing assembly 120, the inertial measurement sensing assembly 140, and the tilt sensing assembly 150 through interfaces. The first acceleration sensing assembly 120, the inertial measurement sensing assembly 140, and the tilt sensing assembly 150 can transmit the acquired data to the processing module 110 through interfaces. Preferably, the interface for data transmission is an interface supporting a communication protocol. Preferably, the interface controlling the power supply may be a normal I/O port. The processing module 110 has at least a first state and a second state different from the first state. The first acceleration sensing assembly 120 is capable of controlling the activation or dormancy of the inertial measurement sensing assembly 140 and the tilt sensing assembly 150 by controlling the switching of the first state and the second state of the processing module 110. Preferably, when the sensing terminal 100 adopted in the geological disaster monitoring and early warning system provided in this embodiment is the wireless sensing terminal 102, the first acceleration sensing component 120 can indirectly control the activation or dormancy of the first Lora communication unit 170 by controlling the switching between the first state and the second state of the processing module 110.

Preferably, the first state of the processing module 110 is a sleep state and the second state is an operating state. Preferably, the inertial measurement sensing assembly 140 and the tilt sensing assembly 150 can share a single power control interface. Preferably, in the actual deployment of the sensing terminal 100, the initial state is that the processing module 110 is in the first state, the power supply of the inertial measurement sensing component 140 and the inclination angle sensing component 150 is cut off to enable the inertial measurement sensing component and the inclination angle sensing component to sleep, and the first acceleration sensing component 120 is in the normal working state to collect vibration data of the object motion in real time.

Preferably, when the vibration data collected by the first acceleration sensing assembly 120 is lower than a preset threshold, the first acceleration sensing assembly 120 maintains the real-time collection of the vibration data of the movement of the object without performing other operations, and the respective components of the sensing terminal 100 maintain an initial state. When the vibration data collected by the first acceleration sensing component 120 changes from being lower than the preset threshold value to being higher than the preset threshold value, the first acceleration sensing component 120 generates a wake-up interrupt signal and sends the wake-up interrupt signal to the processing module 110 through the interface. The processing module 110 switches from the first state to the second state in response to receipt of the wake-up interrupt signal. Preferably, the processing module 110 entering the second state turns on the power supply of the inertial measurement sensing assembly 140 and the tilt sensing assembly 150 through the power supply control interface shared by the inertial measurement sensing assembly 140 and the tilt sensing assembly 150, so that the inertial measurement sensing assembly 140 can collect the track data of the motion of the object, and the tilt sensing assembly 150 can collect the gesture data of the motion of the object. Preferably, the processing module 110 receives the data collected by the first acceleration sensing assembly 120, the inertial measurement sensing assembly 140 and the tilt sensing assembly 150 after entering the second state. Preferably, the processing module 110 in the second state fuses the data collected by the sensing components and transmits the fused data to the computing terminal 200 for computing and analyzing. Preferably, the geological disaster monitoring and early warning system has high requirements on real-time performance. The sensing terminal 100 of the present embodiment preferably uses a wired transmission method and uses the high-speed communication port 221 for data transmission when transmitting data to the computing terminal 200. In a use environment (such as cliffs, etc.) where wiring operation is inconvenient, the geological disaster monitoring and early warning system used in this embodiment adopts the wireless sensing terminal 102 to collect data. Preferably, the wireless sensing terminal 102 performs wireless communication using the configured first Lora communication unit 170. Preferably, the first Lora communication unit 170 is connected with the processing module 110 through an interface. The processing module 110 can transmit data to the first Lora communication unit 170 through an interface. The processing module 110 may also control the power supply of the first Lora communication unit 170 through an interface. The first acceleration sensing component 120 is capable of indirectly controlling the enabling or disabling of the first Lora communication unit 170 by controlling the switching of the first state and the second state of the processing module 110. Preferably, the processing module 110 is in the first state and cuts off the power supply of the first Lora communication unit 170 through the interface to sleep. When the processing module 110 is in the second state, the processing module 110 only opens the power supply of the first Lora communication unit 170 to perform data transmission when the data collected by the sensing components are fused and then needs to be transmitted to the computing terminal 200. Preferably, when the sensing terminal 100 does not need to transmit data to the computing terminal 200, the processing module 110 cuts off the power supply of the first Lora communication unit 170 through the interface, so that the system power consumption is reduced, and the power consumption waste caused by the electrified operation of the first Lora communication unit 170 when the data transmission is not needed is avoided. When the vibration data collected by the first acceleration sensing component 120 changes from being higher than the preset threshold value to being lower than the preset threshold value, the first acceleration sensing component 120 generates a sleep interrupt signal and sends the sleep interrupt signal to the processing module 110 through the interface. Preferably, the processing module 110 enters the first state of lower power consumption from the second state of higher power consumption in response to the receipt of the sleep signal. The processing module 110 turns off the power to the inertial measurement sensing component 140 and the tilt sensing component 150 through the interface to put them into a sleep state in response to the receipt of the sleep signal. The first acceleration sensing component 120 generates a wake-up signal or a sleep signal by monitoring the relation between the acquired data and the threshold value so as to control the working state of the processing module 110, so that the geological disaster monitoring and early warning system of the embodiment can reduce the power consumption under the condition of normal operation.

Preferably, the sensing terminal 100 of the present embodiment sets the first acceleration sensing component 120, the inertia measurement sensing component 140 and the tilt sensing component 150 on the same board in such a way that the collected data are aligned in the axial direction, so that the processing module 110 is convenient for processing the collected data of the first acceleration sensing component 120, the inertia measurement sensing component 140 and the tilt sensing component 150. Specifically, referring to fig. 18, the first acceleration sensing assembly 120, the inertial measurement sensing assembly 140, and the tilt sensing assembly 150 are disposed on the same plate in axial alignment.

Preferably, the core devices of the first acceleration sensing assembly 120, the inertial measurement sensing assembly 140 and the tilt sensing assembly 150 all include accelerometers. The sensing terminal 100 of the embodiment may set a plurality of sensing components with accelerometer as core devices on a board body with the same circuit structure according to an axis alignment manner, so that at least one parameter (such as a position height, a relative coordinate, etc.) of the mass sensing components is the same, thereby reducing the number of parameters required to be processed when the processing module 110 and the computing terminal 200 of the sensing terminal 100 fuse data acquired by the mass sensing components, realizing rapid processing, and indirectly reducing the time spent by the geological disaster monitoring and early warning system of the embodiment when performing object motion analysis. Preferably, the first acceleration sensing assembly 120, the inertial measurement sensing assembly 140 and the tilt sensing assembly 150 are disposed on the plate body at positions remote from the surrounding mechanical mounting holes, thereby avoiding external stress from being transferred to the sensor. The sensing terminal 100 of the embodiment centers each sensing component on the circuit board inwards, so as to avoid inaccurate data acquisition results of the sensing components caused by the fact that stress generated by the circuit board is transferred to the sensing components placed on the circuit board due to the fact that the sensing terminal 100 is packaged.

Preferably, the components and parts of the cloud server 300, the computing terminal 200, the first Lora communication unit 170, the first acceleration sensing component 120, the inertial measurement sensing component 140, the inclination sensing component 150, the processing module 110, and the like used in this embodiment are the same as those of embodiment 1, embodiment 2, and embodiment 3, and are not described herein again.

This embodiment is a further improvement of embodiment 1, embodiment 2, embodiment 3 and embodiment 4, and the repeated description is omitted. In this embodiment, the universal object motion analysis system based on the intelligent motion sensing terminal provided by the invention can be a power transmission line engineering safety monitoring and early warning system. The universal object motion analysis system can acquire vibration data, attitude data and track data by using the sensing terminal 100 in the field of power transmission line engineering safety monitoring and early warning, calculates and analyzes the inclination of the electric power iron tower and the elliptical galloping of the power line by using the calculating terminal 200, detects dangerous conditions of the electric power iron tower and the galloping of the power line, and uploads a calculation and analysis result to the cloud server 300 by using the calculating terminal 200 to process corresponding dangerous conditions, thereby realizing digital upgrading of the power transmission line engineering safety monitoring.

In the field of safety monitoring and early warning of power transmission line engineering, the traditional technical scheme uses an acceleration sensor to measure displacement data, but the acceleration sensor is difficult to measure the track of movement in space, so that the measurement error is large, the track is measured by using a video concentric circle monitoring method, the power consumption of equipment is high, and the construction and installation are inconvenient. The power transmission line engineering safety monitoring and early warning system provided by the embodiment analyzes the conditions of the power line galloping track, the power tower inclination and the like based on the sensing terminal 100 capable of collecting vibration data, gesture data and track data simultaneously, and uploads the analysis result to the cloud server 300 to realize safety monitoring and early warning.

The power transmission line engineering safety monitoring and early warning system provided by the embodiment comprises a sensing terminal 100, a computing terminal 200 and a cloud server 300. The sensing terminal 100 may be provided with sensing components including a first acceleration sensing component 120, a second acceleration sensing component 160, and/or an inertial measurement sensing component 140 and/or an inclination sensing component 150.

Preferably, the sensing terminal 100 may include one or a combination of several of the processing module 110, the first and second

acceleration sensing assemblies

120 and 160, the inertial measurement sensing assembly 140, and the tilt sensing assembly 150. The first acceleration sensing component 120, the second acceleration sensing component 160 and/or the inertial measurement sensing component 140 and/or the tilt sensing component 150 are respectively connected with the processing module 110 through interfaces. The second acceleration sensing component 160 and/or the inertial measurement sensing component 140 and/or the tilt sensing component 150 can perform data acquisition directly or indirectly in response to instructions generated by the first acceleration sensing component 120 based on changes in the acquired data.

Preferably, the processing module 110 has at least a first state and a second state different from the first state. The first acceleration sensing component 120 is capable of controlling the activation or dormancy of the second acceleration sensing component 160 and/or the inertial measurement sensing component 140 and/or the tilt sensing component 150 by controlling the switching of the first state and the second state of the processing module 110. The first state of the processing module 110 is a sleep state and the second state is an active state.

Preferably, in an actual deployment, in an initial state, the processing module 110 is in a first state; the first acceleration sensing component 120 is in a working state with normal power supply; the second acceleration sensing component 160 and/or the inertial measurement sensing component 140 and/or the tilt sensing component 150 are in a powered down sleep state.

When the data collected by the first acceleration sensing component 120 exceeds the preset threshold, the first acceleration sensing component 120 generates an interrupt signal and sends the interrupt signal to the processing module 110 through the interface. The processing module 110 switches from the first state to the second state in response to receipt of the interrupt signal. The processing module 110 entering the second state turns on the power supply of the second acceleration sensing component 160 and/or the inertia measurement sensing component 140 and/or the inclination sensing component 150 through the interface according to the use requirement, so that the second acceleration sensing component 160 and/or the inertia measurement sensing component 140 and/or the inclination sensing component 150 perform data acquisition, and the processing module 110 transmits the data acquired by each sensing component to the computing terminal 200 for computational analysis.

Preferably, the frequency of vibration data that can be acquired by the second acceleration sensing assembly 160 is higher than that of the first acceleration sensing assembly 120. The first acceleration sensing component 120 is provided with a first threshold value and a second threshold value higher. When the threshold value acquired by the first acceleration sensing component 120 is lower than the first threshold value, the first acceleration sensing component 120 does not generate an interrupt signal to switch the first state of the processing module 110 to the second state. The first acceleration sensing component 120 keeps the data acquisition from other operations. When the threshold value acquired by the first acceleration sensing component 120 is higher than the first threshold value and lower than the second threshold value, the first acceleration sensing component 120 keeps acquiring data while generating an interrupt signal so that the processing module 110 is switched from the first state to the second state in response to the receiving of the interrupt signal, at this time, the first acceleration sensing component 120 can accurately acquire vibration data, and the processing module 110 only needs to turn on the power supply of the inertial measurement sensing component 140, so that the inertial measurement sensing component 140 acquires track data. The processing module 110 processes the data collected by the first acceleration sensing component 120 and the inertial measurement sensing component 140, and then transmits the processed data to the computing terminal 200 for computational analysis, and the processing module 110 does not need to start the second acceleration sensing component 160. When the threshold value of the first acceleration sensing component 120 is higher than the second threshold value, the first acceleration sensing component 120 cannot accurately collect the data, and the processing module 110 needs to start the second acceleration sensing component 160 to collect the data while starting the inertial measurement sensing component 140 to collect the track data.

Preferably, the sensing terminal 100 of the present embodiment sets one or more of the first acceleration sensing component 120 and the second acceleration sensing component 160, the inertia measurement sensing component 140 and the inclination sensing component 150 on the same board in a manner of being axially flush with each other so that the collected data is aligned, so that the processing module 110 is convenient for processing the data collected by one or more of the first acceleration sensing component 120 and the second acceleration sensing component 160, the inertia measurement sensing component 140 and the inclination sensing component 150.

Preferably, the core devices of the first acceleration sensing assembly 120, the second acceleration sensing assembly 160, the inertial measurement sensing assembly 140 and the tilt sensing assembly 150 all include accelerometers. The sensing terminal 100 of this embodiment may set a plurality of sensing components with accelerometer as core devices on a board body with the same circuit structure according to an axis alignment manner, so that at least one parameter (such as a position height, a relative coordinate, etc.) of the mass sensing components is the same, and thus, the number of parameters required to be processed when the processing module 110 of the sensing terminal 100 and the computing terminal 200 perform fusion processing on data collected by the mass sensing components can be reduced, and rapid processing can be implemented, so that the time spent by the power transmission line engineering safety monitoring and early warning system of this embodiment when performing object motion analysis is reduced.
