In this regard, embodiments of the present invention will provide a solution for seismic monitoring using mobile devices.
Example 1
The embodiment of the invention provides a method for realizing seismic monitoring of mobile equipment, which can be applied to the mobile equipment, wherein the mobile equipment can comprise a bottom layer processor and a main processor, and as shown in FIG. 1, the method can comprise the following steps:
s1) standardizing a virtual seismic sensor and a register which is mapped with the virtual seismic sensor;
s2) allowing the bottom processor to be used for identifying suspected earthquake events and calculating earthquake key data;
s3) configuring the bottom processor to write the seismic key data into the register;
s4) intervening in the main processor to obtain the seismic key data through sensor events of the virtual seismic sensor;
and S5) configuring the main processor to transmit the seismic key data to a seismic processing center.
In some implementations, the mobile device can include a cell phone, a smart tablet, etc., and the underlying processor and the main processor in the mobile device can both be microprocessors. The underlying processor may include one or more low power microprocessors such as Digital Signal Processors (DSPs), network Processors (NPUs) or deep learning Processors, microcontrollers, field Programmable Gate Arrays (FPGAs), hardware accelerators, etc., and has the characteristics of fast Processing of image, audio, and video data, efficient mathematical computation, and the capability of Processing sensor signals. The main processor may include a high power consumption microprocessor such as a Central Processing Unit (CPU), and the main processor has a high dominant frequency and can run most of codes and abundant applications in an operating system of the mobile device. In modern smart phones or tablets, a CPU, a DSP, an intellectual property core (IP core), and the like are generally integrated in a System-on-Chip (SoC) architecture, and the operating states of the CPU and the DSP may be determined by executing a specific instruction, monitoring a current of a specific circuit, reading a System log, observing infrared thermal imaging, and the like, so that whether the CPU and/or the DSP is in a sleep state may be determined. In the embodiment of the invention, aiming at the power consumption characteristics of the processor of the mobile equipment, the bottom processor is used for executing the earthquake monitoring, and the main processor is used for executing the earthquake key data transmission, so that the practical and feasible low-power consumption earthquake monitoring is realized.
Further, embodiments of the invention provide for the host processor to access and transfer data from the underlying processor using a standardized and implemented virtual seismic sensor. On a mobile device, the sensors may include physical sensors, including acceleration sensors, and may also include gyroscopes and/or magnetometers, and the like. A virtual (or simulated) sensor instance may be created on a mobile device for a particular operating system of the mobile device based on the sensor stack architecture defined by the operating system. For example, in the Android operating system, sensors such as a tilt detector, a linear accelerator, and a pedometer are all virtual sensor instances, such as a pedometer, which is a standardized virtual sensor instance defined according to a sensor stack architecture based on the underlying hardware of an acceleration sensor and an underlying processor. In view of this, in an exemplary example of the embodiment of the present invention, the virtual seismic sensor may be specified based on an Android operating system, where the specification may be to create a sensor according to a sensor stack architecture in an operating system of a mobile device, and specifically may include:
s101) based on an acceleration sensor and a bottom processor, creating a virtual sensor instance on a hardware abstraction layer, and obtaining a sensor handle of the virtual sensor instance, wherein the type identifier of the virtual sensor instance is a seismic sensor;
s102) taking the virtual sensor instance as a virtual seismic sensor.
Wherein, step S101) and step S102) may be executed by the manufacturer platform of the mobile device for the seismic processing center, or may be completed by the manufacturer platform license of the mobile device after being executed by the seismic processing center. In an advantageous embodiment, in step S101), in addition to the acceleration sensor, a gyroscope and/or a magnetometer, a temperature sensor, or the like may be used to assist, calibrate, the physical sensor, so as to achieve a higher accuracy of the virtual seismic sensor. In an operating system of the mobile device, the virtual seismic sensor can be registered with information such as the name, type, version, resolution, energy consumption and the like of the standard virtual seismic sensor; for example, in the Android operating system, the virtual seismic sensor may be registered to the sensor manager specifically with the aforementioned information in order to obtain system support; meanwhile, the virtual seismic sensor can be permitted to be a wake-up sensor or a sensor with a wake-up authority by the manufacturer platform, so that the mobile device main processor can be awakened in time in a dormant state, and data of the virtual seismic sensor can be transmitted within a certain time through an awakening mechanism. It should be noted that the vendor platform may be a (virtual or physical) server-based network element; the seismic processing center may be a (virtual or physical) server-based network element; in the embodiment of the present invention, a network element may be a virtual node or an entity device providing a service in a communication network; the permission can be that the manufacturer platform provides the seismic processing center with the required authority for implementing the seismic monitoring to the seismic processing center and/or the mobile equipment; with respect to whether or not to permit, illustratively, the permitted can be authenticated in any of the listed ways: whether any designated credentials or data are exchanged offline, whether any designated credentials or data are exchanged online, whether any designated credentials or data are present on the mobile device, whether any designated credentials or data are present as held by the seismic processing center, etc., although it is understood that other non-listed designated means or content may be present to authenticate; all statements herein may be understood as being within the scope of embodiments of the present invention.
The sensing data for the canonical virtual seismic sensors may be generated by the underlying processor and acceleration sensors. The sensed data may be recorded in a variety of ways, for example, registers mapped to virtual seismic sensors (with data) may be specified. In some cases, registers in the underlying processor may be directly designated as registers for data mapping with the virtual seismic sensors, at which time the sensed data may be synchronously transmitted so that the data generated by the underlying processor and the acceleration sensors are synchronously read in real time. In still other cases, a register in the underlying processor may be designated as a register having a data mapping with the virtual seismic sensor, and data generated by the underlying processor and the acceleration sensor may be recorded in the register, then retrieved from the register and mapped and recorded to a logical storage location, such as a buffer formed in a chain table, an array, etc., where the sensed data is data in the buffer, and the sensed data may be transmitted asynchronously, so as to reduce the difficulty of transmitting application data in the operating system of the mobile device. It is to be noted that the sensing data recording of the virtual seismic sensors can be implemented by using one or a combination of various ways according to actual needs.
In an advantageous disclosed embodiment, the vendor platform may specifically permit the underlying processor to be configured with a monitoring application configured for identifying suspected seismic events and calculating seismic critical data, which may be formed (e.g., compiled, packaged, etc.) by a seismic processing center. In particular, the monitoring application may be configured to:
s201) acquiring real-time data of the acceleration sensor;
s202) identifying whether the acquired real-time data is a suspected seismic event or not based on a seismic wave feature identification algorithm;
s203) when the real-time data are identified to be suspected seismic events, calculating seismic key data based on a seismic key data processing algorithm.
The seismic wave feature recognition algorithm may extract seismic feature data from real-time data (seismic data), determine a similarity probability between the seismic feature data and the seismic feature data corresponding to a reference seismic event, and if it is determined that the similarity probability exceeds a configured similarity probability threshold, recognize that the acquired real-time data is a suspected seismic event (the suspected seismic event may be a category, which is also equivalent to the case where the acquired real-time data is recognized as the category), that is, the seismic event that causes the mobile device to vibrate at present is the suspected seismic event. In the identification process, the current real-time data can be used, and the cached data of the acceleration sensor and the data after the current moment can be further used for identifying the seismic waves.
And selecting a corresponding data processing mode according to the actually used seismic key data. Illustratively, the seismic key data may include an identifier of a mobile device, a timestamp, latitude and longitude of the mobile device, and calculated P-wave arrival time, S-wave arrival time, intensity and Peak Displacement (PD), etc., and the identifier of the mobile device and the latitude and longitude, etc. data may not be currently transmitted but may be transmitted in a preconfigured manner at a specified time; for example, according to a calculation formula of the seismic key data such as the arrival time and intensity of the P-wave, a function corresponding to the calculation formula is used as a data processing mode used in a seismic key data processing algorithm. In the calculation process, the current real-time data and the cached data of the acceleration sensor can be used, and the data after the current moment can be further used to finish the calculation of the earthquake key data. The underlying processor may be configured to write the seismic critical data to the aforementioned register, thereby treating the seismic critical data as one of the sensed data of the virtual seismic sensor; it should be added that the sensing data of the virtual seismic sensor may also include data that is defined according to specific requirements and needs to be recorded, such as specific characteristic data of seismic waves.
The vendor platform may also permit the host processor to be configured with a transmission application for seismic critical data that is operable to:
s301) obtaining the seismic key data through the sensor events of the virtual seismic sensor.
Wherein the transfer application may be licensed as one of the applications of the operating system. The virtual seismic sensors may be assigned a reporting mode, and the sensor events of the virtual seismic sensors may be defined by a data structure of event content fields, which may be used to record one or more of the seismic critical data. For example, the reporting mode of the virtual seismic sensor in the Android operating system may be a continuous mode or a variable mode, etc., for example, the virtual seismic sensor may generate sensor events in the continuous mode according to a sampling rate parameter, which may be passed by the transmission application to a batch processing function in the sensor stack architecture.
The transfer application may be specifically configured to:
s311) obtaining seismic critical data in sensor events of the virtual seismic sensor through a callback function, wherein the callback function is configured to register in an operating system of the mobile device through a sensor handle; the callback function can also be called a listener, and can also be registered in an operating system of the mobile equipment through the type identifier of the sensor; the sensor handle and the type identifier of the sensor can be regarded as the sensor identifier. Therefore, the embodiment of the invention further realizes the purpose of sending the seismic key data generated by the bottom processor to the transmission application program through the virtual seismic sensor. Conversely, in general, in the operating system of the mobile device, the operating system usually masks an underlying processor (such as a DSP) to prevent an application program executed by a main processor in the operating system from directly accessing data of the underlying processor, which makes it difficult for a transmission application program to acquire data obtained by the underlying processor performing seismic monitoring.
In some cases, the underlying processor may be configured to send an interrupt signal to the main processor while the main processor of the mobile device is in a sleep state, thereby waking the main processor. Illustratively, this may be achieved by the aforementioned monitoring application, which may be used to trigger the sending of the interrupt electrical signal after identification of a suspected seismic event or after calculation of seismic critical data; wherein the sending of the interrupt signal may be triggered without determining whether the host processor is in a sleep state. It will be appreciated that the particular signal sent may be selected based on the sleep state of the main processor for program logic rationality. For example, when the host processor is in a sleep state, the sending of an interrupt signal may be triggered to wake up the host processor, while when the host processor is not in a sleep state, the sending of a message on the bus between the host processor and the underlying processor may be triggered to notify the host processor.
The host processor may be interposed for obtaining seismic critical data from sensor events of virtual seismic sensors, and may include any one of:
s401) when the main processor is not in a dormant state and a sensor event is not generated, selecting the process for transmitting the application program as a blocking state;
s402) when the main processor is not in a dormant state and a sensor event is generated, selecting a process for transmitting an application program as an operating state, and reading the sensor event to obtain earthquake key data in the sensor event;
s403), when the main processor is not in a dormant state, the process of the transmission application program is placed in a ready queue, wherein the process has the highest priority of the ready queue and is higher than the process of a typical application program in the ready queue, and the typical application program can comprise an entertainment application program, a social application program and the like.
Here, the execution order is not limited in steps S401) to S403). It should be noted that, in the process of seismic monitoring, the intervention may be that the hardware resource of the main processor is obviously used by the operating system or the application program (relative to the dormant state or the idle state), and the obvious use may be determined based on a specific instruction display, a current monitoring of a specific circuit, a system log record display or an infrared thermal display and the like.
In order to prevent implementation of security measures such as mobile device counterfeiting, device authentication may be performed on the mobile device, and the device authentication may include: an intervening host processor for authenticating the transmitting application; if the hardware unique identifier of the mobile equipment and the time stamp record of the manufacturer server for transmitting the application program to access the mobile equipment are both consistent with the hardware unique identifier and the time stamp record recorded on the manufacturer server, the authentication is passed; if one of the two is not consistent, the authentication is not passed and the vendor server of the vendor platform or the server of the seismic processing center may refuse to communicate with the mobile device. Wherein the device authentication may be performed after each boot of the mobile device and upon arrival of a specified authentication period, the mobile device may provide the hardware unique identifier and the timestamp record to the vendor server and receive the authentication result.
The authenticated mobile device may communicate with a vendor server and/or a server of the seismic processing center. Configuring a host processor for transmitting seismic critical data to a seismic processing center, comprising:
configuring the transfer application to:
s501) sending the obtained earthquake key data to a server of an earthquake processing center,
s502) sending the obtained earthquake key data to a manufacturer server of the mobile equipment, so that the manufacturer server forwards the earthquake key data to a server of an earthquake processing center.
The execution sequence is not limited in steps S501) to S502), and one of step S501) and step S502) may be specifically used, and step S502) may enable the vendor server to perform the data forwarding function and the data use witness function. The communication connection between the mobile equipment and the seismic processing center, the communication connection between the mobile equipment and the manufacturer server, and the communication connection between the manufacturer server and the seismic processing center can be encrypted; meanwhile, on the mobile equipment, encryption communication between the bottom processor and the main processor can be realized based on modes such as a security chip or system security service and the like, so that data security in a period from generation to uploading of the earthquake key data can be realized.
