Specific embodiments of the present invention have been shown by way of the above drawings and will be described in more detail below. The drawings and the written description are not intended to limit the scope of the inventive concepts in any way, but rather to illustrate the inventive concepts to those of ordinary skill in the art by reference to specific embodiments.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Fig. 1 schematically illustrates a schematic diagram of a wireless acquisition system 100 of operational data of an unstable device 140 in accordance with an embodiment of the present invention.
As shown in fig. 1, the wireless acquisition system 100 includes a wireless communication station 110, a first type of sensor 120, and a second type of sensor 130. The first type sensor 120 and the second type sensor communicate wirelessly with the wireless communication station 110 by wireless communication means such as ZigBee.
As used herein, the term "non-steady state device" as opposed to the term "steady state device" may include devices such as intermittent operation, multi-operating, transient operation, and the like. Such devices require higher monitoring requirements than steady state devices such as single-state devices.
In some embodiments of the present invention, the first type of sensor 120 may be a wireless magnetic flux sensor that may detect one or more operational data including a device start-up and shut-down condition, rotational speed, and on-load and off-load conditions.
In some embodiments of the present invention, the second type of sensor 130 may be one or more of a wireless vibration sensor, a wireless temperature sensor, a wireless image sensor, a wireless sound sensor, a wireless infrared sensor, which may detect one or more operational data including vibration, temperature, image, noise, infrared imaging data.
In some embodiments of the present invention, the first type of sensor 120 and the second type of sensor 130 may be wireless sensors powered by batteries.
The wireless acquisition system 100 is configured to perform a wireless acquisition method provided by embodiments of the present invention for wirelessly acquiring operational data of the non-stationary device 140. Fig. 2 schematically illustrates a flow chart of a method 200 of wireless acquisition of operational data of non-stationary device 140, in accordance with an embodiment of the invention.
First, in step 210, the first type sensor 120 monitors first operational data of the non-steady state device 140 in real time. As previously described, the first operational data may be one or more of a plant start-up and shut-down condition, a rotational speed, and a loaded and unloaded condition.
In step 220, the obtained first operational data is compared to a first operational data threshold. If it is determined that the first operational data meets the first operational data threshold, the wireless communication station 110 wirelessly transmits a wake-up instruction to the second type sensor 130 in step 230. If the first operational data is determined not to satisfy the first operational data threshold, the first type of sensor 120 continues to monitor the first operational data of the non-steady state device 140 without the wireless communication station 110 sending a wake-up instruction to the second type of sensor 130. The first operational data threshold may be indicative of a first operational data threshold for the non-steady state device 140 to transition from a current state to another state, such as from a shutdown state to a startup state, from an idle state to a loaded state, from a low speed operating state to a high speed operating state, and so on.
In step 240, in response to receiving the wake-up instruction from the wireless communication station 110, the second type sensor 130 checks whether a steady-state acquisition instruction is received from the wireless communication station 110.
In step 250, the second type sensor 130 enters a steady state acquisition state in response to receiving a steady state acquisition command from the wireless communication station 110. In this steady state acquisition state, the second type of sensor 130 acquires second operational data of the non-steady state device 140. As previously described, the second operational data may be one or more of vibration, temperature, image, noise, infrared imaging data. In the steady-state acquisition state, the second type sensor 130 detects the operation condition of the non-steady-state device in the steady-state operation state through the acquisition of the second operation data.
In the wireless acquisition method, two types of sensors are used for monitoring the non-steady-state equipment, so that good monitoring of the non-steady-state equipment is ensured on the basis of saving electric power. For example, during a non-steady state device shutdown, a first type of sensor monitors first operational data of the device in real time. The first type of sensor compares the first operational data with a first operational data threshold during real-time monitoring to determine whether the device is to enter a start-up state from a shutdown state. If the first operational data meets the first operational data threshold, the device is indicated to begin entering a power-on state. At this time, the wireless communication station transmits a wake-up instruction to the second type sensor by wireless to wake up the second type sensor. The second type of sensor, upon receiving the wake-up instruction, checks whether a steady-state acquisition instruction is also received from the wireless communication station. During the start-up process, the non-steady state device requires a certain time to reach a steady state operation. Thus, after waking up the second type sensor, the wireless communication station does not immediately send a steady state acquisition command to the second type sensor, but waits for the device to enter a steady state operation from a start-up state. In the process, the second type sensor checks whether a steady state acquisition command is received from the wireless communication station. When the device enters a stable operation state from a start-up state, the wireless communication station transmits a steady-state acquisition instruction to the second type sensor, so that the second type sensor acquires second operation data of the device in response to receiving the steady-state acquisition instruction. The second operational data is indicative of an operating state of the device during steady state.
It should be noted that the above is only an exemplary description. Besides the condition that the wireless acquisition method enters the starting state from the stopping state and then stably runs, the wireless acquisition method provided by the invention can be also suitable for the conditions that non-steady-state equipment enters the loading state from the idle state and then stably runs, and enters the high-speed operation from the low-speed operation and then stably runs and the like. The first operation data threshold value adopts each first operation data threshold value of transition from the non-steady-state equipment to different states under different conditions.
To conserve power of the second type of sensor, in the exemplary embodiment, second type of sensor 130 is periodically alternated between a listening state and a sleep state prior to receiving a wake-up instruction. In the sleep state, the second type sensor 130 is in the sleep state, consuming little power. However, in order to be able to receive the wake-up instruction, the second type sensor 130 needs to wake up from the sleep state at intervals, and enter the listening state to check whether the wake-up instruction is received. If in the listening state the second type sensor 130 checks to find that a wake-up instruction is received from the wireless communication station 110, the second type sensor 130 is woken up. If the second type sensor 130 does not receive a wake-up instruction from the wireless communication station 110 in the listening state, it returns to the sleep state after the end of the listening period, waiting for the next listening period.
To further conserve power of the second type of sensor, in an exemplary embodiment, the wake-up instructions sent by the wireless communication station 110 to the second type of sensor 130 may be periodic wake-up instructions. In response to receiving a periodic wake-up instruction from the wireless communication station 110, the second type sensor 130 is alternately in a wake-up state and a sleep state with a certain wake-up period. In the sleep state, the second type sensor 130 sleeps with little power consumption, while in the awake state, the second type sensor 130 checks whether a steady-state acquisition instruction is received from the wireless communication station 110. If the second type of sensor 130 checks to find that a steady state acquisition command has been received from the wireless communication station 110, the second type of sensor 130 enters a steady state acquisition state and acquires second operational data of the device. And if the second type sensor 130 does not receive a steady-state acquisition instruction from the wireless communication station 110 in the awake state, it returns to the sleep state after the end of the awake period, waiting for the next awake period. This approach can further conserve power for the second type of sensor 130 as compared to an approach that is always in the awake state once the wake-up instruction is received.
To more accurately monitor the state of the device, the wake-up period of the second type sensor 130 may be variable to adaptively adjust according to the operating state of the device. For example, upon detecting that the non-stationary device enters a start-up state from a shutdown state, the wireless communication station transmits a periodic wake-up command of variable period to the second type of sensor, and the period of the wake-up command varies as the non-stationary device approaches a steady-state operating state in order to better monitor the device following the operating state of the non-stationary device.
In one embodiment, to accurately monitor and evaluate the operating condition of the device 140 in the steady state operating condition, the second type of sensor 130 in the steady state acquisition state continuously acquires the second operating data of the device 140 once every first predetermined time, the continuously acquired time being a first time threshold, the first time threshold being less than the first predetermined time.
In the above embodiment, the second operation data continuously collected within the first time threshold is a first parameter index, through which a specific operation index of the non-steady-state device 140 can be estimated.
Further, the wireless acquisition method 200 may further include, if the first operation data no longer satisfies the first operation data threshold during the first time threshold, that is, the non-steady state device 140 is no longer in a steady state operation state, the second type sensor 130 no longer needs to perform steady state acquisition on the second operation data of the device 140. At this time, the wireless communication station 110 transmits an acquisition breaking instruction to the second type sensor 130 by wireless. In response to receiving the acquisition interrupt instruction, the second type sensor 130 stops acquiring the second operation data and records the time that the acquisition has been continued.
In the above embodiment, since the device 140 exits from the steady operation state for some reason (e.g., a fault, a device shutdown, etc.) during the continuous acquisition of the second operation data by the second type sensor 130, the continuous acquisition time of the second operation data by the second type sensor 130 is less than the first time threshold, and thus the first parameter index cannot be obtained. In this case, the second operational data that has been continuously acquired can still be retained and the corresponding continuous acquisition time recorded for further analysis.
In the above embodiment, the determination of whether the first operation data satisfies the first operation data threshold may be performed by the first type sensor 120 or the wireless communication station 110. In the case that the first type sensor 120 determines whether the first operation data satisfies the first operation data threshold, if the first type sensor 120 determines that the first operation data satisfies the first operation data threshold, the first type sensor 120 wirelessly transmits a wake-up indication signal to the wireless communication station 110. In response to receiving the wake-up indication signal from the first type of sensor 120, the wireless communication station 110 wirelessly transmits a wake-up instruction to the second type of sensor 130 in step 230.
Alternatively, in the case where it is judged by the wireless communication station 110 whether the first operation data satisfies the first operation data threshold, if the wireless communication station 110 judges that the first operation data satisfies the first operation data threshold, the wireless communication station 110 wirelessly transmits a wake-up instruction to the second type sensor 130 in step 230.
The invention provides a wireless trigger type acquisition scheme for unsteady state equipment operation data. Compared with a wired data acquisition scheme, the wireless data acquisition system has the advantages that the acquisition capacity similar to that of the wired data acquisition system can be achieved, and the advantages and economic benefits of wireless data acquisition in installation, construction and maintenance costs can be maintained.
On the other hand, compared with a wireless timing acquisition scheme, the wireless triggering acquisition scheme provided by the invention carries out triggering acquisition according to a real-time second-level working condition, and in order to ensure the effectiveness and high quality of data acquisition, a mechanism of judging while acquiring is adopted in the acquisition process, and each sensor can be informed to stop acquisition when the running state of the equipment does not meet a threshold value, so that the power consumption waste of invalid data acquisition is avoided.
