Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

Example 1:

referring to fig. 1, the present embodiment provides a method for analyzing repair workload of front-end devices in a smart city, which includes the following steps:

The method and the device depend on the server, the specified equipment terminal and the mobile terminal to finish together. Before the implementation of the scheme of the application, the front-end equipment corresponding to the specified equipment terminal fails, so that manual or automatic repair processing is achieved, the repair condition needs to be analyzed, and the repair workload is also analyzed. The failure condition of the front-end device is preferably a regional failure, that is, not only the software and hardware of the front-end device itself fails, but also both the wired communication channel and the wireless communication channel fail.

As described in the above steps S1-S3, the server sends an operation execution instruction to a preset designated device terminal through a preset wired communication channel; the appointed equipment terminal is used for controlling front-end equipment, and the front-end equipment is preset with an instruction executor; the operation execution instruction comprises a first operation, a second operation, …, and an nth operation; the operation execution instruction is also accompanied by positioning data of a first position, a second position, … and an nth position; n is an integer greater than 2; after receiving the operation execution instruction, the appointed equipment terminal broadcasts a channel construction request to the mobile terminal in the preset area by adopting a Bluetooth communication technology; a specified device terminal and n mobile terminals which pass the channel construction request respectively construct Bluetooth communication channels, and respectively send the positioning data of the first position, the second position, … and the nth position to the n mobile terminals; the n mobile terminals include a first mobile terminal, a second mobile terminal, …, and an nth mobile terminal.

The present application relates to a smart city, and the servers in the smart city can be configured in any feasible manner, such as a single cluster server or a distributed server. And the inherent communication mode of the server and the equipment terminal is wire communication, and a specific communication medium is an optical fiber. The front-end equipment is a terminal arranged on the site, and can exist in any form, such as street lamps, traffic lights and the like, so that the front-end equipment is used as a component of intelligent illumination and intelligent traffic of a smart city. The front-end equipment is provided with an instruction executor to receive the instruction of the server and carry out corresponding operation. Of course, the front-end device can also be provided with a sensor to sense the corresponding sensing signal as a basis for the server decision. The sensor is for example a temperature sensor, an image sensor, etc. In addition, the operation execution instruction of the application is not single, but n operation instructions are split, so that the possibility is provided for subsequent multi-position analysis, and the comprehensiveness of workload analysis is improved. In addition, the operation execution instruction is also accompanied by positioning data of the first position, the second position, …, and the nth position, which correspond to the n operations, respectively.

And after receiving the operation execution instruction, the appointed equipment terminal broadcasts a channel construction request to the mobile terminal in the preset area by adopting a Bluetooth communication technology. The Bluetooth communication technology is short-distance communication technology, the cost is low, and almost all mobile terminals are provided with Bluetooth modules, so that the Bluetooth communication technology can be used for realizing data transmission between a specified device terminal and the mobile terminals. And respectively constructing a Bluetooth communication channel by the appointed equipment terminal and the n mobile terminals which pass the channel construction request, and respectively sending the positioning data of the first position, the second position, the … and the nth position to the n mobile terminals. Wherein the n mobile terminals correspond to the first operation, the second operation, …, and the nth operation, respectively, and also correspond to the first location, the second location, …, and the nth location, respectively, which will be described in detail in the following steps. It should be noted that the bluetooth communication channel is constructed in the present application, because the workload analysis is performed by two closed communication loops, one of which is an inherent wired communication channel, and the other of which is also implemented by a terminal of a specified device, a mobile terminal, and a server, and data transmission is performed between the terminal of the specified device and the mobile terminal by using the bluetooth communication channel.

The present application uses a special method to determine whether the front-end device is faulty, so to determine whether the fault is completely repaired, the present application also performs a corresponding analysis, which is also the origin of the positioning data of the first position, the second position, …, and the n-1 th position of the present application. When a large-scale fault occurs, the fault causes include not only software and hardware of the front-end device, a wired communication channel, but also a wireless network (artificial shielding may exist), and therefore, it is necessary for the designated front-end device to send the acquired sensing data to the server in time (because artificial damage may exist, especially when the sensing data includes image data and the image data shoots the face of a destructor). At this time, the wired communication channel is blocked, and the wireless network is also shielded (or a part of the signal base station is damaged), so the method and the system utilize the movable characteristic of the mobile terminal to avoid the shielded area so as to transmit the sensing data to the server. Meanwhile, positioning data of the first position, the second position, … and the nth position are required to be sent to the server through the mobile network, and the positioning data indicate the range of wireless signal failure.

The feedback mobile terminal is different from the first mobile terminal, the second mobile terminal, …, and the nth mobile terminal, and is named as the feedback mobile terminal. The sensor is for example an image sensor. And if the sensing data is not successfully sent to the server through the wired communication channel, the wired communication is not smooth, so that the server is communicated with the server by means of the mobile terminal in an indirect communication mode. And n mobile terminals for feedback are needed, so that the purpose is to transmit data at a position available for a mobile network and determine the fault range of a wireless signal by means of other positions.

Therefore, the corresponding numbering of the mobile terminal is realized, and different positioning data can be correspondingly sent. Since the mobile terminal is in motion, some locations are inconvenient for some mobile terminals to go to, for example, the a mobile terminal goes south, and the B location is located north of the a mobile terminal, so the a mobile terminal is not suitable to be matched to the B location, that is, the location of the B location should not be sent to the a mobile terminal. Therefore, according to the method and the device, the virtual track of the mobile terminal is estimated through the current position and the moving direction, the positions corresponding to different mobile terminals are determined according to the principle of proximity, and the positioning data is correspondingly sent.

The distance calculation processing may use any feasible algorithm, for example, if a position is respectively perpendicular-lined to n virtual tracks, then n perpendicular lines may be obtained, and then n minimum distance values corresponding to the position may be obtained, and then the other positions are similarly processed, and then the minimum distance value sequences corresponding to n positions (that is, the n minimum distance sequences corresponding to the n virtual tracks are obtained, because the minimum distance value sequences corresponding to n positions are equivalent). Of course, on the basis of a certain virtual track, taking n positions as n circle centers, and respectively making circumscribed circles, the radius of each circumscribed circle is the minimum distance value. Since there are n members per minimum distance sequence, all minimum distance values are n × n in total, so that an n × n matrix can be constructed. The horizontal rows of the n x n matrix correspond to the virtual tracks, and the vertical columns correspond to the positions, so that the corresponding relation between the virtual tracks and the positions is established. The traversal method can try all the possibilities once, and is suitable for being adopted due to the limited membership of the n × n matrix of the present application.

The reason why the sum is minimum is to make the location where information is actually transmitted close to n positions as much as possible and to reduce the moving distance of the mobile terminal. Therefore, two ways can be used for the mobile terminal to transmit data, one is to require the mobile terminal to accurately go to the first position, the second position, … and the nth position, respectively, and then transmit data; secondly, the mobile terminal is required to send data only at the position closest to the corresponding position on the virtual track. The selected members have row and column numbers, which reflect the corresponding relationship between the virtual track and the position, and the vertical column numbers of all the selected members are different, and one member is selected from each row of the n × n matrix, so that no number conflict occurs, and the most suitable corresponding relationship between the mobile terminal and the position can be constructed, namely, the positioning data of the first position, the second position, the … and the nth position is correspondingly sent to the n mobile terminals according to the corresponding relationship between the horizontal row of the n × n matrix and the virtual track and the corresponding relationship between the vertical column of the n × n matrix and the first position, the second position, the … and the nth position by taking the n row and column numbers as the basis. The specific meaning is that the corresponding relation between the horizontal rows of the n × n matrix and the virtual track makes it possible to realize the correspondence between the virtual track and the position by means of the matrix according to the corresponding relation between the vertical columns of the n × n matrix and the first position, the second position, … and the nth position, and then the corresponding position and the mobile terminal can be obtained according to the specific n row-column numbers.

As described in the above steps S4-S8, the designated device terminal and the first mobile terminal perform the first cooperative image acquisition processing, so that the designated device terminal controls the instruction executor to execute the first operation, and the first mobile terminal acquires the image of the front-end device when executing the first operation in real time, thereby obtaining a first image sequence; the first mobile terminal performs first image sequence sending processing to send the first image sequence to the appointed equipment terminal, and performs first hash calculation processing to perform hash calculation on the first image sequence to obtain a first hash value; the first mobile terminal carries out first hash value sending processing so as to move to the first position, and then sends the first hash value to the server through a mobile network; the first mobile terminal and the ith mobile terminal continuously perform ith cooperative image acquisition processing, ith image sequence sending processing, ith hash calculation processing and ith hash value sending processing until nth hash value sending processing is completed; wherein i is an integer greater than 1 and less than or equal to n; the ith cooperative image acquisition processing means that the appointed equipment terminal controls the instruction executor to execute the ith operation, and simultaneously, the ith mobile terminal acquires the image of the front-end equipment when executing the ith operation in real time, so as to obtain an ith image sequence; the ith image sequence sending processing means that the ith mobile terminal sends the ith image sequence to the appointed equipment terminal and carries out ith hash calculation processing so as to carry out hash calculation on the ith image sequence to obtain an ith hash value; the ith hash calculation processing means that the ith mobile terminal performs hash calculation on the ith image sequence to obtain an ith hash value; the ith hash calculation processing means that the ith mobile terminal moves to an ith position and then sends the ith hash value to the server through a mobile network; and the appointed equipment terminal sends the first image sequence, the second image sequence, … and the nth image sequence to the server through the wired communication channel.

The cooperative image acquisition processing refers to that the front-end equipment executes corresponding operation, and the mobile terminal shoots the front-end equipment at the moment, so that whether the execution capacity of the front-end equipment is recovered can be determined, wherein the obtained image sequences are different according to different instructions, for example, when the front-end equipment is a street lamp, the instructions can flash at intervals, and the image sequences can be videos. In addition, the mobile terminal also needs to perform hash calculation on the image sequence to obtain a hash value, and the purpose of the hash value is to reduce the data volume of data transmitted by the mobile terminal through the mobile network. Because the complete image sequence is sent to the server through the wired communication channel, the mobile terminal only needs to send the corresponding hash value. Any feasible hash algorithm, such as SHA 256 algorithm, may be used for the hash calculation. The hash algorithm is an abstract algorithm, which can process an input with an arbitrary length into an output with a fixed length, and has an irreversible characteristic, and thus can be applied to the present application, that is, although a mobile terminal of the present application only transmits a corresponding hash value, since a server can receive a corresponding image sequence, it is possible to verify whether the hash value is correct by using the image sequence.

Similarly, the appointed device terminal and all the mobile terminals are subjected to cooperative image acquisition processing, image sequence sending processing, hash calculation processing and hash value sending processing, so that the appointed device terminal can acquire all the image sequences, the server acquires all the hash values, and then the appointed device terminal sends the first image sequence, the second image sequence, … and the nth image sequence to the server through the wired communication channel.

As described in the above steps S9-S10, the server receives the first hash value, the second hash value, …, and the nth hash value, receives the first image sequence, the second image sequence, …, and the nth image sequence, and then determines whether the first hash value, the second hash value, …, and the nth hash value are correspondingly matched with the first image sequence, the second image sequence, …, and the nth image sequence, so as to obtain a first determination result; judging whether the first image sequence, the second image sequence, … and the nth image sequence are correspondingly matched with the first operation, the second operation, … and the nth operation or not to obtain a second judgment result; and if the first judgment result and the second judgment result are completely matched, the server judges that the front-end equipment of the smart city is repaired.

After receiving the hash value and the image sequence, the server determines whether the hash value and the image sequence are matched correspondingly, which is to determine whether a wired communication channel and a wireless network are unobstructed, so that when a communication fault exists, any data is not received or is inaccurate, the hash value and the image sequence cannot be completely matched. Whether the first image sequence, the second image sequence, … and the nth image sequence are correspondingly matched with the first operation, the second operation, … and the nth operation is judged again, so as to determine whether the front-end equipment accurately executes the corresponding operations to determine the condition of the execution capability repair of the front-end equipment. If the first judgment result and the second judgment result are completely matched, the server judges that the front-end equipment of the smart city is repaired, which can also be called as the mode that the front-end equipment repair workload of the smart city reaches the expectation, namely the front-end equipment repair workload of the smart city is 100% (at least 100% in terms of communication and instruction execution).

The hash algorithm used by the server for hash calculation needs to be the same as the hash algorithm used by the corresponding image sequence at the mobile terminal, and this may be implemented by using a pre-agreed fixed hash algorithm, for example, only using the SHA 256 algorithm. If the data is correct, theoretically, the first verification hash value, the second verification hash value, …, and the nth verification hash value should be identical to the first hash value, the second hash value, …, and the nth hash value. Thus, determining whether the image sequence matches the hash value in this manner avoids redundancy in the mobile terminal transmitting duplicate data.

According to the method for analyzing the repair workload of the front-end equipment of the smart city, the operation execution instruction is sent to the preset appointed equipment terminal; a specified device terminal adopts a Bluetooth communication technology broadcast channel to construct a request; constructing a Bluetooth communication channel; carrying out first collaborative image acquisition processing; performing first image sequence sending processing and first Hash calculation processing; carrying out first hash value sending processing; continuously performing ith cooperative image acquisition processing, ith image sequence sending processing, ith hash calculation processing and ith hash value sending processing until nth hash value sending processing is completed; sending the first, second, …, and nth image sequences to the server; the server obtains a first judgment result; obtaining a second judgment result; if the intelligent city front-end equipment is completely matched, the server judges that the intelligent city front-end equipment is repaired, and the repair workload analysis is realized.
