[0026] The present invention discloses a roller coaster safety monitoring device for measuring the safety performance of a roller coaster (not shown). Figure 6 In some embodiments, the safety monitoring device includes a wireless sensor 1, a wireless gateway 2 and a storage space 3, wherein the safety monitoring device performs the safety monitoring method when working, and the wireless sensor 1 includes a wireless attitude stress sensor 11 and a wireless tilt sensor 12. The wireless tilt sensor 12 is installed on the column of the roller coaster (not shown) to sense the tilt of the column. Under normal circumstances, the tilt of the column is close to the strain value of the track, and the position of the column is relatively fixed. The strain value on the track can be obtained relatively stably by directly measuring the tilt of the column. The wireless attitude stress sensor 11 is installed on the seat of the roller coaster (not shown), which can be used to obtain the relevant data of the acceleration of the seat in each direction, the movement angle of the seat, the yaw angle and the strain value of the seat in each direction during the operation of the amusement equipment in real time. The wireless gateway 2 includes a protocol module 21, a wireless communication module 22, a data storage module 23 and a data upload module 24. The wireless communication module 22 is communicatively connected to the wireless sensor 1, and is used to receive data from the wireless sensor 1 and store the data in the data storage module 23. The protocol module 21 is preset with the connection direction protocol of the wireless gateway 2 and the wireless network regarding the wireless sensor 1. The storage space 3 is set in the cloud storage (not shown), and is communicatively connected to the data storage module 23 and the data upload module 24, and is used to receive data from the wireless gateway 1 and analyze the uploaded data.

[0027] In some embodiments, the safety monitoring device also includes a wireless strain tester 4, which is installed on the track of the roller coaster and is communicatively connected to the wireless communication module 22, and is used to measure the stress change trend on the track when the roller coaster passes through different positions, and compare it with the measurement value of the wireless inclination sensor 12, so as to timely obtain the abnormal state of the roller coaster and issue a warning in time.

[0028] Furthermore, the wireless attitude stress sensor 11 includes an inertial measurement unit 13, a wireless communication unit 14 and a strain conditioning unit 15. The wireless communication unit 14 is communicatively connected to the wireless communication module 22 and is used to transmit the data in the wireless attitude stress sensor 11 to the wireless gateway 1. The inertial measurement unit 13 is connected to the strain conditioning unit 15, wherein the inertial measurement unit 13 is used to measure the acceleration of the roller coaster seat in all directions, the movement angle of the seat and the yaw angle. The wireless attitude stress sensor 11 also includes a stress sheet 16, which is attached to the roller coaster seat and is used to sense the stress size of the roller coaster seat at all angles. The stress sheet 16 is connected to the strain conditioning unit 15, and the strain conditioning unit 15 converts the strain signal in the stress sheet 16 into a voltage signal for subsequent transmission to the wireless gateway 1 via the wireless communication unit 14. The stress sheet 16 and the inertial measurement unit 13 jointly ensure that the entire wireless attitude stress sensor 11 performs real-time measurement and recording of the angle change value and strain value of the roller coaster seat in all directions.

[0029] The above roller coaster safety monitoring method is as follows, which is used to measure the safety performance of the roller coaster. Please refer to Figures 1 to 6 , the safety monitoring method specifically includes:

[0030] Step S1: the wireless gateway 2 sends a wake-up instruction, and the wireless sensor 1 receives the wake-up instruction and enters a standby state.

[0031] When the wireless sensor 1 is not in the standby state, it is in a more power-saving state, and the wireless sensor 1 always remains in the dormant state when it does not receive a wake-up command, so as to save the power consumption of the wireless sensor 1 and enhance the sustainable monitoring of the wireless sensor 1. When it is necessary to detect the safety status of the roller coaster, the wireless gateway 2 sends a wake-up command to the wireless sensor, and the wireless sensor 1 receives the wake-up command and enters the standby state, waiting for the detection to start.

[0032] Step S2: the wireless gateway 2 sends a start signal to the wireless sensor 1 , and the wireless sensor 1 starts to collect the position information and movement information of the roller coaster and stores them in the wireless gateway 2 .

[0033] The wireless gateway 2 sends a start signal to the wireless sensor 1. After receiving the start signal, the wireless sensor 1 in the standby state starts to monitor the roller coaster seat. The wireless attitude stress sensor 11 and the stress sheet 16 in the wireless sensor 1 are arranged behind the roller coaster seat. The stress and angle changes in all directions of the seat can be obtained according to the real-time position of the roller coaster, which enhances the sensing accuracy of the wireless sensor 1. The column (not shown) installed on the roller coaster in the wireless sensor 1 is used to sense the inclination of the column. Under normal circumstances, the inclination of the column is close to the strain value of the track, and the position of the column is relatively fixed. The strain value at the corresponding moment on the track can be obtained more stably by directly measuring the inclination of the column. In the subsequent processing, the angle change measured by the wireless attitude stress sensor 11 can be matched and compared with the inclination change on the column to realize the monitoring of the roller coaster state. The wireless attitude stress sensor 11 and the wireless tilt sensor 12 transmit the acquired values ​​to the wireless gateway 2 via the wireless communication unit 14 , and store them temporarily in the data storage module 23 in the wireless gateway 2 .

[0034] Step S3: the wireless gateway 2 sends an end signal to the wireless sensor 1, and the wireless sensor 1 stops collecting data and enters a dormant state.

[0035] After completing the collection, the wireless gateway 2 sends an end signal to the wireless sensor 1. The wireless sensor 1 stops collecting and after the data is completely transmitted, it enters the dormant state to reduce the power consumption inside the wireless sensor 1, and waits to enter the standby state again after receiving the wake-up command next time. The data in the wireless gateway 2 is temporarily stored in the data storage module 23 and waits for subsequent processing.

[0036] Step S4: the wireless gateway 2 transmits the location information and the motion information to the storage space 3 .

[0037] The position information, strain value and angle temporarily stored in the data storage module 23 are transmitted to the storage space 3, and the above data are analyzed to complete the safety monitoring of the roller coaster.

[0038] The safety monitoring method arranges the wireless sensor 1 on the seat of the roller coaster so that the wireless sensor 1 can directly monitor the changes of the seat on the roller coaster, thereby improving the monitoring accuracy. When the wireless sensor 1 does not need to perform detection, it is in a standby state and a dormant state, thereby reducing the power consumption of the wireless sensor 1 when no data is collected, thereby ensuring the continuous monitoring time of the safety monitoring method.

[0039] Furthermore, when transmitting the data in the wireless gateway 2 to the storage space 3, it is necessary to organize the various types of data in the wireless gateway 2. In some application scenarios, the wireless gateway 2 transmits the location information and motion information to the storage space 1, specifically including:

[0040] Step S41: the wireless gateway 2 reads the original data of the location information and the motion information, analyzes the original data and classifies it to form group data.

[0041] After being turned on, the wireless gateway 2 establishes a network connection with the programmable controller (not shown) and reads the data inside the programmable controller through the protocol in the protocol module 21. After the wireless gateway 2 obtains the real-time position of the roller coaster and the strain value, angle and other motion information of the roller coaster, it analyzes the above raw data according to time, position information, change trend and other information and classifies them into group data.

[0042] Step S42: convert the format of the group data and transmit it to the storage space 3 via the router.

[0043] The electrical signals such as the group data are converted into JOSN format, transmitted to the router through the data uploading module 24, and then uploaded to the storage space 3 by the router.

[0044] Step S43: In response to the completion of the group data transmission, the wireless gateway 2 enters a standby state.

[0045] After the group data transmission is completed, the wireless gateway 2 enters the standby state, reads the data of the programmable controller, and transmits the data of the programmable controller to the storage space 3.

[0046] Specifically, in some application scenarios, the group data includes running acceleration data, running angle data, yaw angle data and strain value data. Among them, the inertial measurement unit 13 measures the acceleration data, running angle data and yaw angle data, and the running angle data includes roll angle data and pitch angle data. Specifically, the inertial measurement unit 13 can use TM431 (Transducer M431, sensor M431), TM431 has excellent dynamic and static performance in roll / pitch / yaw measurement, and excellent yaw stability, which can meet the acceleration data, running angle data and yaw angle data of the high-speed roller coaster for real-time measurement, and can use wireless transmission to transmit the relevant data to the wireless gateway 2. The stress sheet 16 is used to measure the strain value of the roller coaster seat in all directions during operation, and the wireless inclination sensor 12 is used to measure the strain value of the roller coaster column. The stress values ​​of the two regions obtained are transmitted to the wireless gateway 2 respectively, so as to obtain the state of the roller coaster in real time, realize the early warning of the failure of the roller coaster state, and ensure the safety of tourists.

[0047] In order to monitor the running status of each area of ​​the roller coaster, multiple wireless sensors are provided, such as a wireless attitude stress sensor 11 and a wireless tilt sensor 12. Therefore, in order to realize synchronous or alternating acquisition of multiple wireless sensors 1, a crystal oscillator (not shown) can be used as a system clock. In some application scenarios, it specifically includes:

[0048] Step S01: Acquire a crystal oscillator as the system clock of the wireless gateway 2 .

[0049] The crystal oscillator is connected to the circuit of the wireless gateway 2, and a vibration signal is sent to the entire wireless gateway 2 according to a preset time, so that the crystal oscillator can be used as a system clock.

[0050] Step S02: the wireless gateway 2 sends synchronization instructions to the plurality of wireless sensors 1 at first preset time intervals.

[0051] The crystal oscillator is used to send synchronization instructions to multiple wireless sensors 1 according to the first preset time. Multiple wireless sensors 1 can adjust their own clocks regularly to ensure that multiple wireless sensors 1 can always collect data synchronously or alternately as needed during the entire monitoring period.

[0052] Step S03: the wireless sensor 1 adjusts the internal timer according to the synchronization instruction to make it consistent with the system clock.

[0053] The wireless sensor 1 receives the clock signal sent regularly by the wireless gateway 2, and adjusts the internal timer after receiving the clock signal to make it consistent with the system clock generated by the crystal oscillator, so that multiple wireless sensors 1 can always collect synchronously or alternately as needed during the entire monitoring period.

[0054] After the storage space 3 receives the group data, it is also necessary to analyze the monitored data to achieve safety monitoring of each area of ​​the roller coaster. The data analysis includes acceleration analysis, stress strain value analysis, and angle data analysis. In some application scenarios, the analysis steps specifically include:

[0055] Step S6: Acquire the group data transmitted by the wireless network card 2, and compare the group data with the standard data.

[0056] Taking acceleration analysis as an example, the storage space 3 receives acceleration data transmitted by the wireless network card 2 for a long time, forms an acceleration curve with the acceleration data, and compares it with the national standard GB8408.

[0057] Step S61: In response to the group data being within the standard data range, record and upload the group data to a database.

[0058] According to the above comparison, it is determined whether the maximum acceleration value at that location exceeds the national standard. If the acceleration is within the standard, the multiple data are stored in a database (not shown) in the storage space 3. Among them, the maximum acceleration value and the corresponding position and running angle data are usually transmitted to the database after 10Hz low-pass filtering, which further ensures the integrity of the data in the database and provides a more comprehensive basis for subsequent measurement comparison.

[0059] Step S7: Compare the group data with the data in the database to form an analysis report of the group data.

[0060] The data uploaded to the database is compared with the historical data in the database. In order to ensure the accuracy of the analysis and to promptly discover abnormal losses in corresponding areas, the acceleration data uploaded to the database is compared with the monthly acceleration characteristic curve and the annual acceleration characteristic curve, and an analysis report is generated to evaluate the losses of the entire roller coaster based on months or years, so that areas of abnormal losses on the roller coaster can be discovered in a timely manner.

[0061] The above analysis step takes the stress curve as an example, and compares the stress curve with the standard to determine whether it exceeds the allowable safety range. When the stress curve is within the safety range, the maximum value of the strain value measured by each stress sheet 16 and the corresponding position and running angle data are transmitted to the database, and the strain value is compared with the monthly strain value characteristic curve and the annual strain value characteristic curve in the database to generate an analysis report, which evaluates the stress changes in the corresponding areas on the roller coaster and the overall loss of the roller coaster in terms of months or years, and can promptly discover the areas of abnormal loss on the roller coaster.

[0062] The above analysis steps take the inclination curve as an example, obtain the maximum and minimum values ​​of each inclination on the roller coaster column, compare the two with the standard, and determine whether the maximum and minimum values ​​are within the allowable safety range. When the maximum and minimum values ​​are within the safety range, the maximum and minimum values ​​of the inclination are transmitted to the database. Similarly, the maximum and minimum values ​​of the inclination are compared with the monthly inclination characteristic curve and the annual inclination characteristic curve to generate an analysis report to monitor the wear and tear of the roller coaster columns and tracks.

[0063] In addition, when the measured group data does not meet the safety requirements, that is, in response to the group data being outside the marked data range,

[0064] Step S62: Stop the roller coaster, evacuate tourists in time, and check the areas that do not meet the safety requirements and the roller coaster as a whole to ensure the safety of tourists and roller coaster equipment.

[0065] Understandably, for cost considerations, in actual demand, a roller coaster does not perform safety monitoring every time it is turned on. Therefore, after a roller coaster completes a safety monitoring, it can perform safety monitoring again after a period of time or after adjustment according to the actual number of times the roller coaster runs. In some application scenarios, the wireless gateway 2 sends a wake-up command, and the wireless sensor 1 receives the wake-up command and enters the standby state, specifically including:

[0066] Step S11: the wireless sensor 1 is in a dormant state, switches to a wake-up state after a second preset time interval and maintains the state for a third preset time.

[0067] After entering the sleep state, the wireless sensor switches to the wake-up state at an interval of a second preset time and maintains the wake-up state for a period of time. Specifically, the wireless sensor 1 can switch from the sleep state to the wake-up state every 30 seconds and maintain the wake-up state for 1 second, further extending the standby time of the wireless sensor 1 and reducing cost consumption.

[0068] Step S12: When the wake-up instruction is within the third preset time, the wireless sensor 1 enters the standby state.

[0069] When the wireless sensor 1 is in the waiting state and receives a wake-up instruction, the wireless sensor 1 switches from the waiting state to the standby state, waiting for the instruction of the wireless gateway 2 to collect data on the roller coaster.

[0070] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
