The device for controlling and processing the radio monitoring equipment based on the android Http service is provided by the invention, and comprises the following steps:
a processor configured to execute computer-executable instructions;
a memory storing one or more computer-executable instructions that, when executed by the processor, perform the steps of the above-described method for implementing an android Http-based control process for a radio monitoring device.
The processor for implementing control processing for a radio monitoring device based on the android Http service is configured to execute computer-executable instructions, and when the computer-executable instructions are executed by the processor, the steps of the method for implementing control processing for a radio monitoring device based on the android Http service are implemented.
The computer readable storage medium of the present invention, wherein a computer program is stored thereon, said computer program being executable by a processor to implement the above steps of the method for implementing the android Http service based control process for a radio monitoring device.
As shown in fig. 1, the handheld radio monitoring device consists of 4 main components. Utilize android mobile phone/dull and stereotyped to replace the computer, cooperation is to digital baseband board and the radio frequency module of portable design to reach portable handheld purpose.
After the battery in the original factory is removed, the android mobile phone/the flat panel is uniformly powered by the battery module, the battery in the original factory is removed, interference of filtering and removing impurity waves in the supplied direct current is guaranteed, and the sensitivity of the system is improved; the power supply time of the system is increased, and the capacity of the matched battery is enough to support the system to operate for more than 2 hours in the full power consumption operation mode. The battery capacity is calibrated to 20000mAh (can be carried on an airplane), a long endurance version (32000mAh) and a fixed plate.
The android phone/tablet personal computer is connected with the digital baseband board through a USB3.0 connecting line with a shielding. The android mobile phone/tablet computer uses a serial port communication protocol to issue a work instruction to the digital baseband board and receive a processed result.
The digital baseband board is composed of an FPGA, a Beidou GPS chip and the like, and performs the functions of radio frequency module control, digital down conversion, digital signal real-time processing, timestamp marking, touch method acquisition and the like.
The radio frequency module receives radio frequency signals and converts the radio frequency signals into intermediate frequency signals to the digital baseband board, and the radio frequency module comprises a filter, an amplifier, an AD converter and the like.
The direct current power supply can charge the battery and also provide support for long-time fixed use of the equipment.
As shown in fig. 2, the android program system architecture is composed of an Http service and an equipment control App, and the equipment control App supports a user to provide a UI and operate with the user in a handheld mode. And the Http service is independent, and provides service support for the equipment control App and the site service. Through site service, the handheld portable radio monitoring device can access a monitoring network for remote operation of a center.
The Http service of the present device is developed based on AndServer. The AndServer provides standard Http protocol support, and the equipment provides Restful service and WebSocket duplex communication mode based on the AndServer. Because the device is required to face two different network environment modes, a resource scheduling parameter cm is added in a service request protocol of Restful and WebSocket.
Restful service request format is as follows:
http://{IP.Port}/{resource}/{resourceid}/cm:{cm}/{para}；
resource is a resource name that can be used by the service, and is shown in table 1 in the present device:
the Http service enables a device to have good expansion capability and maintainability by introducing device capability description. An example of the Json returned by the device description is as follows:
where Id identifies a specific device, features specify a list of capabilities that the device possesses, feature is a specific capability, para below it specifies the available parameters and their ranges for the feature, and the default values for the parameters.
resource _ id is a unique identifier corresponding to the service instance and is obtained by a resource get method. If the resource _ id of the Http service is not available, the resource is defined to be queried.
cm is a resource scheduling parameter, which indicates that the Http service allocates resources according to the value of cm for scheduling according to the available resources (idle cpu, idle memory, and network instantaneous occupied bandwidth) of the current device. Each resource has a default cm value. The service request may fail when the device does not have sufficient resources to meet the cm requirement. The format of the resource scheduling parameter cm is shown in fig. 3.
And when the http service receives the service request and analyzes the protocol, obtaining 3 cm components, if the CPU use threshold of the system exceeds 40% at the moment and waits for 10ms, and if the CPU use threshold is not reduced to be below 40%, returning a failed request, wherein the failed content is service busy. The same logic is applied to the memory and the network, and the task management module calls the driving module to execute the hardware instruction only if the logic is satisfied.
The protocol analysis is responsible for processing the received service request, and the processed content comprises instruction analysis, public resource scheduling and log recording. The processing is carried out by using the AOP (development on tangent plane) technology. The instruction parses into corresponding resource objects according to the Restful service request format of fig. 3 and the resource list of table 1. And the common resource scheduling processes the cm parameter. The log records the time and content of the service request and the processing result.
By introducing task management, the decision of the parallelism and conflict of a plurality of operations can be realized, and the device can execute the operations according to the plan. The core of task management is the maintenance of task data. The composition of the task data is as follows:
TABLE 2 task data
The task scheduling logic is normally as shown in figure 4.
Wherein the execution task is child thread execution to support concurrency. After the data in the task processing queue is processed, the device does not immediately enter the task scheduling of the next cycle, the device enters a waiting cycle, in the waiting cycle, the device monitors the resource use condition of the system, and when the CPU and the memory of the device resource are both lower than the preset threshold (20% of the CPU by default and 2000KB of the memory), the new task scheduling cycle is restarted. The longest waiting period is 1 second, so that the response delay of the real-time task is avoided from being too large.
In the task execution sub-thread, when two task execution threads use the same equipment channel and execution conflict occurs, the task execution module interrupts tasks with low priority, and the tasks with the same priority are executed in turn (time division multiplexing), thereby realizing the requirement of executing multiple tasks by a single channel. The logic is shown in fig. 5.
Unlike the logic that the interruption of the operating system needs to be pushed and then restored, the discrete processing characteristic of the radio monitoring equipment task is utilized, and only the accumulated time length and the state of the task and the last execution time need to be recorded. And returning the interrupted task to the task scheduling queue again for scheduling again in the next task cycle. Different from an operating system, the state of the equipment channel needs to be recovered after interruption, and the task parameters can be issued only after the equipment channel is kept controllable.
As shown in fig. 8, the use time of each channel in the time division multiplexing logic is controlled within 100ms to avoid a pause perceivable to human eyes in data display and storage. The number of time-division multiplexing tasks is controlled to be 4 at most, so that the stop feeling is reduced and the shortage of resources is avoided.
The device driving module converts the task parameters into byte instruction sequences which can be accepted by the digital baseband board and ensures the time sequence among the instructions. Therefore, the realization point is time synchronization and high-speed data exchange with a digital baseband board.
The difficulty of time synchronization is to prevent time synchronization failure caused by GPS time acquisition error when GPS satellite searching capability is insufficient. And when connecting with the network of the telecom operator, the cross validation is carried out by combining the operator time. Its time synchronization logic is shown in fig. 7.
The time synchronization logic is executed once at the start of the http service and once every hour thereafter.
The high-speed data exchange refers to that http service on the android phone/tablet accesses a high-speed solid-state storage disc on the digital baseband board. Due to the limitation of the USB3.0 transmission rate, the data of the digital baseband board is stored in the high-speed solid-state memory disk on the board, and the digital baseband board retains the frequency spectrum and sound data within the last 15 minutes. When a user finds that an abnormal signal appears in the operation and needs to trace back, the abnormal data frame can be directly and quickly accessed. The high-speed data exchange of the device driving module can efficiently provide the data to be stored to the data high-speed storage module on the premise of not influencing the transmission of the data to the front end. The key to realizing high-speed data transmission is to reduce the waiting and processing time consumption of data in the transmission process, so that the targeted processing is adopted for the data characteristics of radio monitoring. The storage related data processing logic on the digital baseband board is shown in fig. 8.
As shown in table 3, the data unit has the following structure:
TABLE 3
| Field(s) | Type (B) | Description of the invention |
| Time stamp | uint32 | Number of milliseconds from acquisition start time to current time |
| Segment number | uint16 | Starting from 0, represents the second segment of the spectrum |
| Spectral data | short[] | Array of frequency spectra, unit 0.1dBm |
The time stamp is an integer, so that subsequent sequencing and insertion operation can be conveniently and quickly performed. The length of the frequency spectrum data in the primary acquisition process is fixed and is filled in by the subsequent packaging parameters.
According to the principle of digital signal processing, the size of the segment number is related to the intermediate frequency bandwidth of the device, in principle one intermediate frequency bandwidth is used as a segment. Therefore, in the data acquisition process, the device can continuously output the data units without splicing the frequency spectrum.
The size of each data storage block is taken from the medium frequency bandwidth of the monitoring device. The value rule is shown in table 4.
TABLE 4
| Medium frequency bandwidth (MHz) | Data storage block threshold (MB) |
| 40 | 1024 |
| 80 | 2048 |
| 100 | 4096 |
| 200 | 8192 |
If a large data storage block is used when the bandwidth of the medium frequency band of the device is small, the data accumulation process becomes long, the data transmission continuity becomes poor, and the USB3.0 bandwidth cannot be fully utilized. And when the data accumulation exceeds the threshold of the data storage block, packaging the data parameters into the data storage block to be transmitted, and writing the data storage block into a high-speed storage medium.
The structure of the encapsulated data storage block is shown in table 5.
TABLE 5
| Field(s) | Type (B) | Description of the invention |
| Block head mark | byte | 0xFFFA |
| Time of acquisition | date | The time of starting acquisition of the measurement |
| Block number | uint8 | Identification of this data block |
| Number of units | uint8 | Counting of data unitsNumber of |
| Length of cell | uint8 | Length of data unit |
| Data unit | byte[] | Data of data unit |
Once the acquisition starts, the acquisition time of all the subsequent data storage blocks is the same, which can be used to distinguish the data acquisition of different tasks, the block sequence number is a continuous integer, the sequence number of the first data block at the start of the acquisition is 0, and the sequence numbers are sequentially increased. The acquisition time, along with the block sequence number, may uniquely identify a data block. The data high-speed storage module can establish parallel storage file handles according to the acquisition time and sequentially write the received data blocks into corresponding files. In the process of transmitting data from the digital baseband board to the android mobile phone/tablet, the two ends only need to transmit and receive the data, and complex control and waiting are not needed, so that the transmission efficiency is improved.
In practical tests, the data transmission speed of the 200MHz medium frequency bandwidth can reach 4.66 Gbps.
