Description
Technical Field
The present invention relates to the technical field of server congestion processing, and in particular, to a method for determining queue congestion when a server communicates with a plurality of positioning devices and a storage medium.
Background
With increasing popularization of Beidou vehicle-mounted positioning equipment, the number of the Beidou vehicle-mounted positioning equipment connected to the server is increased dramatically. In order to improve the performance of big dipper vehicle positioning equipment, the location information request between server and the big dipper vehicle positioning equipment adopts asynchronous response's communication mode, specifically: after receiving the positioning information sent by the Beidou vehicle-mounted positioning equipment, the server responds to the Beidou vehicle-mounted positioning equipment, then places the positioning information of the Beidou vehicle-mounted positioning equipment into a queue to wait in a queue, and then sequentially processes a plurality of positioning information in the queue. When the number of Beidou vehicle-mounted positioning devices connected to the server is too large, the server is easy to block a queue due to too much positioning information waiting in the queue. When the server queue is blocked, the positioning information needs to be automatically limited or development, operation and maintenance personnel needs to be informed to expand the capacity of the server.
At present, a funnel algorithm is generally adopted for judging server queue blockage: and configuring an upper threshold of the queue, and judging the queue to be blocked if the upper threshold of the queue is exceeded, so as to limit the current of the positioning information. Because big dipper vehicle-mounted positioning equipment can keep the locating information in advance when not having the signal in, wait to reach the server again to all locating information supplements of keeping in when the signal is good, if the locating information quantity of supplementing the biography is more, then the quantity of the locating information in the queue can increase suddenly and exceed the queue upper limit threshold value, under this condition, the funnel algorithm can judge to block up, but the server does not actually take place the jam in the true sense, can eliminate the jam condition by oneself in the short time, need not to carry out current-limiting or dilatation.
Disclosure of Invention
The invention aims to solve the technical problem of providing a server queue blockage judging method which is high in judging accuracy.
The inventor finds that the quantity of the positioning information in the queue can be suddenly increased to exceed the queue upper limit threshold value due to the fact that the individual Beidou vehicle-mounted positioning equipment transmits the positioning information additionally, the funnel algorithm can judge that the queue is blocked, and therefore the positioning information is limited or development, operation and maintenance personnel are informed to expand the capacity of the server. However, in this case, the server does not actually generate a true congestion, and the congestion condition can be automatically eliminated in a short time, which belongs to a false congestion, and it is not necessary to limit the location information or expand the capacity of the server. The Beidou vehicle-mounted positioning equipment can regularly generate positioning information containing the current position information and the current positioning time of the Beidou vehicle-mounted positioning equipment, and then the positioning information is sent to the server, so that the server can determine the running track of the vehicle according to the plurality of positioning information reported by the Beidou vehicle-mounted positioning equipment. And after receiving the positioning information, the server puts the positioning information into a queue to be queued for processing. In the case of true jamming, the waiting time of the positioning information in the queue is longer than that in the normal case, so that when the server processes the positioning information, the current time of the server is much later than the positioning time of the positioning information. In the case of false jamming caused by poor communication signals, the positioning information is transmitted to the server after the vehicle-mounted equipment waits until the signals are good, and therefore the server processes the positioning information for a long time later than the positioning time. It can be seen that whether a true or false jam occurs, it causes the current time when the server processes the positioning information to be much later than the positioning time. However, in a certain period of time, communication signals are not good usually only in a few big dipper vehicle-mounted positioning devices, that is to say, in a certain period of time under the condition that true blockage does not occur, positioning information that only a few big dipper vehicle-mounted positioning devices sent can be delayed by a long time than positioning time when being processed by the server, and the proportion of the big dipper vehicle-mounted positioning devices in the total number of the big dipper vehicle-mounted positioning devices is very small. And under the condition of taking place true jam, in certain time quantum, the locating information that most big dipper vehicle positioning equipment sent all need wait in the queue for a long time just can be handled by the server, so then the locating information that most big dipper vehicle positioning equipment sent can be late for a long time than the positioning time when being handled by the server, and the proportion of taking up of this part big dipper vehicle positioning equipment in big dipper vehicle positioning equipment total number is very big. Therefore, the method and the device have the idea that the number of the Beidou vehicle-mounted positioning devices sending the positioning information is counted for the positioning information which is processed by the server and is later than the positioning time for a long time in a certain time period, so that whether the Beidou vehicle-mounted positioning devices belong to false blockage or true blockage is judged according to the proportion of the number of the Beidou vehicle-mounted positioning devices to the total number of the Beidou vehicle-mounted positioning devices.
In order to solve the above-mentioned technical problem, a queue congestion determining method for determining congestion of a queue when a server communicates with a plurality of positioning devices according to the present invention determines that the queue of the server is in a congested state if a congestion condition is satisfied, wherein the congestion condition includes: among the positioning devices, the positioning devices reaching the preset number have the phenomenon that the positioning information waiting processing exceeds the preset time length.
Optionally, the congestion condition further includes that the number of the positioning information in the queue exceeds a queue upper limit threshold, and if the phenomenon occurs in a preset number of positioning devices and the number of the positioning information in the queue exceeds the queue upper limit threshold, it is determined that the server queue is in a congestion state.
Optionally, when the positioning information is taken out from the queue for processing, if it is determined that the generation time of the positioning information is earlier than the current time and exceeds the preset time, it is determined that the positioning device that sends the positioning information has a phenomenon that the positioning information waiting processing exceeds the preset time.
Optionally, if it is determined that the server queue is in a blocked state and it is determined that the timeout times of the positioning devices exceed a preset time threshold, performing current limiting processing on the currently taken out positioning information.
Optionally, as described above, the current extracted positioning information is subjected to current limiting processing, specifically, if a preset random condition is met, the current extracted positioning information is discarded, and is not processed.
Alternatively, the above-mentioned clogging conditions are specifically: the phenomenon occurs in a preset number of positioning devices among the positioning devices within a time interval of a preset length.
Optionally, a timed determination is made whether the jam condition is satisfied.
Optionally, if it is determined that the server queue is in a congestion state, sending a congestion warning message.
Optionally, the preset number is represented as a proportion of the total number of positioning devices.
A computer readable storage medium having stored thereon an executable computer program, the computer program being executed to implement a method of queue congestion determination when a server communicates with a plurality of positioning devices as described above.
According to the queue jam judging method, when positioning information waiting processing exceeds a preset time length in positioning devices of a preset number, the server queue is judged to be in a jam state, and therefore the server queue cannot be judged to be jammed when false jam occurs due to positioning information supplementary transmission. Therefore, the accuracy of the blockage judgment is improved.

Detailed Description
The invention is described in further detail below with reference to specific embodiments.
The driving positioning service system shown in fig. 1 comprises a server and a plurality of Beidou vehicle-mounted positioning devices in communication connection with the server, wherein the Beidou vehicle-mounted positioning devices are respectively installed on different vehicles. The server includes a processor and a computer-readable storage medium storing an executable computer program, the processor executing the computer program to implement the functions of the server.
Each Beidou vehicle-mounted positioning device can regularly generate positioning information containing the current position information and the current positioning time of the Beidou vehicle-mounted positioning device, and then sends the positioning information to a server. And after receiving the positioning information, the server puts the positioning information into a queue to be queued for processing. If too much positioning information is received and the server fails to process the information, the queue may be blocked. Under the condition of blockage, the server needs to limit the current or request operation and maintenance personnel to expand the capacity of the server, so that the server is prevented from running due to overload. Therefore, the server needs to perform congestion determination.
The existing jam judging method is to set an upper threshold for a queue, and once the quantity of positioning information in the queue exceeds the upper threshold of the queue, the queue is judged to be jammed. However, the inventor finds that in an actual scene, a vehicle may enter some road sections with poor communication signals in the driving process, so that Beidou vehicle-mounted positioning devices mounted on the vehicle cannot send positioning information to a server, and in the period with poor communication signals, the Beidou vehicle-mounted positioning devices can temporarily store the positioning information generated in the period in the local machine and wait for the signal to be recovered well and then send the signal to the server. The method is characterized in that the individual Beidou vehicle-mounted positioning equipment is used for judging whether the number of positioning information in a queue is increased suddenly to exceed a queue upper limit threshold value or not due to the fact that the positioning information is additionally transmitted by the individual Beidou vehicle-mounted positioning equipment, and if the blockage condition is simply used for judging the blockage, the situation is judged to be blocked. However, in this case, the server does not actually generate a true congestion, and the congestion condition can be automatically eliminated in a short time, which belongs to a false congestion, and it is not necessary to limit the location information or expand the capacity of the server. The inventor thinks about through thinking, in certain time quantum, it is not good that communication signal appears in the on-vehicle positioning device of few big dipper usually, that is to say, in certain time quantum under the condition of not taking place true jam, can be very late than the positioning time for a long time when only having the positioning information that the on-vehicle positioning device of few big dipper sent by the server processing, mean that, in the middle of whole on-vehicle positioning device of big dipper, only the positioning information of the on-vehicle positioning device of few big dipper leads to it to wait for to handle for a long time because of the signal is not good waits for sending. And under the condition of taking place true jam, in certain time quantum, the locating information that most big dipper vehicle positioning equipment sent all need wait in the queue for a long time just can be handled by the server, so then the locating information that most big dipper vehicle positioning equipment sent can be late for a long time than the positioning time when being handled by the server, mean that, in the middle of whole big dipper vehicle positioning equipment, most big dipper vehicle positioning equipment's locating information is because of waiting to handle in the queue and leads to its wait to handle for a long time. Therefore, the invention has the idea that the number of Beidou vehicle-mounted positioning devices with the phenomenon that the positioning information waiting processing time is long is counted in a certain time period, so that whether the Beidou vehicle-mounted positioning devices are true jamming or false jamming is distinguished according to the proportion of the number of the Beidou vehicle-mounted positioning devices to the total number of the Beidou vehicle-mounted positioning devices.
Based on the above thought, need to carry out the statistics of quantity to the big dipper vehicle positioning equipment that has the long phenomenon of positioning information wait for processing duration, specific statistical approach is as follows:
as shown in fig. 2, after taking out the positioning information queued earlier from the queue, the server extracts the positioning time of the positioning information, and determines whether the positioning time exceeds the preset time by 30 minutes earlier than the current time. If the positioning time is 30 minutes longer than the preset time before the current time, the Beidou vehicle-mounted positioning equipment sending the positioning information is considered to have the phenomenon that the positioning information waiting processing exceeds the preset time. The server is provided with a redis database, and after the fact that the phenomenon that positioning information waiting processing exceeds the preset time length exists in the Beidou vehicle-mounted positioning equipment is determined, the server inquires whether a key value pair with the equipment number of the Beidou vehicle-mounted positioning equipment sending the positioning information as a key exists in the redis database or not. If the key value does not exist, the server creates a corresponding key value pair in a redis database, the key value pair takes the equipment number of the Beidou vehicle-mounted positioning equipment as a key, and the number of times of occurrence of an overtime event that the positioning information of the Beidou vehicle-mounted positioning equipment waits for processing for 30 minutes exceeding a preset time length is taken as a value. Although the number of positioning devices with poor signals is usually small, if the time length is long enough, the positioning devices may have poor signals in a staggered manner, which may statistically exceed a preset number, but this is still only a false jam. In the case of a true blockage, most of the positioning devices will be present for a short period of time. Therefore, the present embodiment adds a time length constraint to further ensure that a false occlusion is not judged to be a true occlusion. In this embodiment, the time length limitation condition is increased by setting the expiration time for the key-value pair to be 30 minutes, and if the key value of the key-value pair is not updated after exceeding 30 minutes, the server deletes the key-value pair. Therefore, only the key value pairs updated within 30 minutes from the current time can be stored in the redis database, and when the number of the key value pairs is counted, the key value pairs updated within 30 minutes are counted, so that the counting of the positioning equipment with the phenomenon before a long time is avoided. And if the redis database has a key value pair taking the device number of the Beidou vehicular positioning device sending the positioning information as a key, adding 1 to the key value of the key value pair. The number of the Beidou vehicle-mounted positioning devices with the positioning information waiting for processing exceeding the preset time length is counted in a key value pair mode.
After the number of the Beidou vehicle-mounted positioning devices with the phenomenon is counted, the server can perform corresponding blockage judgment. In this embodiment, the jam determination process is triggered at regular time, but in other embodiments, when the positioning information is processed, if the positioning time of the positioning information is 30 minutes longer than the current time of the server, the jam determination process is triggered. In this embodiment, the reason why the congestion determination process is set to be triggered at a fixed time instead of being triggered when the positioning information is processed is that key value number scanning is a time-consuming operation, although the congestion state can be determined more timely by triggering the congestion determination process when the positioning information is processed, under the condition that the congestion or the number of location information supplementary transmissions is large, the probability that the positioning time of the positioning information processed by the server exceeds the preset time by 30 minutes before the current time becomes large, so key value number scanning is frequently performed, which greatly increases the load of the server and affects the service processing of the server. The congestion judgment process is set as timing trigger, and in the worst case, the queue congestion is detected only after a set interval duration later than the occurrence of congestion, so that the service processing of the server is not greatly influenced as long as the time interval is not long.
As shown in fig. 3, the blockage determination process is triggered every 3 minutes, specifically: the server firstly judges whether the proportion of the number of key value pairs in the redis database to the total number of the Beidou vehicle-mounted positioning devices exceeds a preset proportion by 10%, if so, the server means that the blocking condition is met, and the phenomenon that positioning information waiting processing exceeds preset time length exists in the positioning devices which reach the preset number in each Beidou vehicle-mounted positioning device is avoided. The server then determines whether the amount of positioning information in the queue exceeds a queue upper threshold, which is set based on the processing power of the server. If yes, the server queue is judged to be in a blocking state currently, so that the global blocking zone bit is set to be true, and blocking alarm information is sent to operation and maintenance personnel.
Under the condition that the server queue is in a blocked state, the flow limiting processing can be carried out to relieve the processing pressure of the server, so that the queue can be recovered to be normal as soon as possible. In this embodiment, the server executes the current limiting process before processing the positioning information, and determines whether to normally process the current positioning information according to an execution result of the current limiting process. The flow of current limiting is as follows: as shown in fig. 2, after counting the number of the beidou vehicle-mounted positioning devices with positioning information waiting for processing exceeding the preset time length, the server determines whether the global blocking flag is true, and if so, further determines whether the key value of the key value pair (the key value is equal to the timeout times of the beidou vehicle-mounted positioning devices corresponding to the key value pair) exceeds a preset time threshold 1000. When the key value of the key value pair exceeds 1000, the positioning information quantity of the Beidou vehicle-mounted positioning equipment is large, in order to enable the queue to recover to normal as soon as possible, the server discards the positioning information of the Beidou vehicle-mounted positioning equipment with excessive positioning information quantity at random, so that the workload of the server is correspondingly reduced, the processing efficiency of the positioning information in the queue is correspondingly improved, and the queue can recover to normal as soon as possible. The random discard procedure specifically: if the key value exceeds a preset time threshold 1000, the server randomly generates a random number from 0 to 99, if the random number is less than 49, the random number means that a preset random condition is met, the positioning information is discarded without processing, otherwise, the positioning information is normally processed.
The above description is only the embodiments of the present invention, and the scope of protection is not limited thereto. The insubstantial changes or substitutions will now be made by those skilled in the art based on the teachings of the present invention, which fall within the scope of the claims.
