As shown in fig. 2, as an alternative embodiment, the first check-sum the second check-sum includes:
sending a network access request to a base station, so that the base station inquires whether the base station is an authorized base station;
receiving random data generated by the base station;
the random data is used in cooperation with the base station to test the link quality of the POS machine, so that the base station can determine whether the POS machine is located at an authorized place according to the link quality data, and if the base station is an authorized base station and the POS machine is located at the authorized place, the POS machine is authorized to access the network.
In this embodiment, the POS device is provided with a SIM card and communicates with the base station, where the network access request refers to a network access registration process when the SIM card communicates each time, and the SIM card needs to report information to the base station to enable the network to determine which base station the SIM card is located. In this embodiment, the authorized base station is a correspondence between a SIM card or POS machine, which is fixed when the SIM card or POS machine is turned on, and the base station, in the present invention, each SIM card or POS machine corresponds to only one base station, and the base station is determined by an application address of the SIM card or POS machine, and once it is determined that the base station is not modifiable during normal use, the SIM card or POS machine can access a network only under the base station by such limitation; the present embodiment also allows a small range of movement of the SIM card and POS under an authorized base station, defined by link quality testing of the SIM card, by detecting the link quality of the SIM card. In this embodiment, by randomly generating a data, determining the link quality of the SIM card by using the transmission process of the random data, so as to determine whether the movement of the SIM card or POS is within an allowable range, thereby determining whether to allow the SIM card to access the network; the invention determines whether the SIM card is open to access authorization or not by inquiring whether the base station corresponds to the SIM or not and carrying out quality test on the link of the SIM card, thereby realizing SIM mobile authorization management, being capable of being used for standardizing the use range of the POS machine with the built-in SIM card and effectively preventing the POS machine from being sold or unauthorized use in different places.
In this embodiment, a fixed communication duration is further set, after the SIM card accesses the network each time, the SIM card only keeps communicating with the base station within the fixed communication duration, and then needs to re-verify the access. The set time period may be 10 minutes, half an hour, or the like, and is set by the manager.
In this embodiment, the base station sends the base station code and the SIM code of the base station to the server, so that the server queries the corresponding relationship between the base station code and the SIM code, and further obtains the corresponding relationship between the base station code and the SIM code returned by the server, and if the base station code corresponds to the SIM code, the base station is an authorized base station; if the base station code does not correspond to the SIM code, the base station is an unauthorized base station; in the embodiment, the corresponding relation between the SIM card or the POS machine and the base station is stored on the server, so that the storage space of the base station is not occupied, the initial authorization is carried out at the cloud end, the base station is not needed in the authorization process, and the data volume stored by each base station is reduced.
As an optional embodiment, the testing the link quality of the POS machine by using the random data in cooperation with the base station includes:
acquiring a first data packet sent by the base station, wherein the first data packet is formed by arranging a plurality of sub-data according to a set sequence, and the sub-data is obtained by dividing the random data by the base station;
and returning the first data packet to the base station, so that the base station determines the delay amount and the packet loss rate of the POS machine according to the data contained in the transmitted first data packet and the data contained in the returned first data packet, and determines the link quality of the POS machine according to the delay amount and the packet loss rate.
In this embodiment, data may be transmitted by using parallel or serial links, but for a POS, the data transmission modes should be kept consistent each time verification is performed, so as to reduce the influence of differences caused by different transmission modes.
In this embodiment, the base station calculates the time difference between the sending time and the receiving time of each sub-data, calculates the cumulative average value of the time differences to obtain the delay amount of the POS machine, and can stop the verification process at any time by adopting the cumulative average value without waiting for the completion of all sub-data transmission. It should be understood that the cumulative average herein refers to the cumulative average of the time differences of all the sub-data in the current test process, and does not include the historical data.
In this embodiment, the base station compares each received sub data with the corresponding sent sub data to determine a data difference, calculates the proportion of the data difference to the data amount of the sent sub data, and further determines whether the first proportion is greater than a set packet loss threshold, if so, marks the sub data as loss, calculates the proportion of the lost sub data as a second proportion, calculates the proportion of the sum of the data differences to the random data as a third proportion, and finally obtains the packet loss rate of the POS machine by a weighted average of the second proportion and the third proportion; the packet loss rate is characterized by two parts, wherein one part is the loss proportion of each sub-data, and if the loss proportion is larger than a set value (such as 0.2, 0.1 and the like), the sub-data is invalid in normal use, and the whole sub-data is considered to be lost at the moment; the other part is the total data loss proportion, namely the ratio of the sum of the data quantity lost by each sub data to the generated random data, which characterizes the stability in the whole data transmission process; in addition, the weighting coefficients of the second proportion and the third proportion can be set by the manager, and can be set according to the substantial requirement of the network quality, for example, 0.2 and 0.8 respectively, which is not limited in the embodiment of the invention.
In the embodiment, the base station calculates the weighted sum of the delay amount and the packet loss rate according to the set weight to obtain the link quality of the POS machine; the delay amount and the weight of the packet loss rate can be determined by a data collection mode, the respective probabilities of the delay and the packet loss rate of the data can be determined by analyzing historical data, and the two probabilities are normalized and then used as the corresponding weights, so that the obtained link quality can be adapted to the condition of the current network environment. Of course, the manager may set two fixed values, for example, 0.5.
In this embodiment, the base station determines the delay amount, the packet loss rate and the allowable range of the link quality of the POS machine according to the history data; if the calculated delay amount, the packet loss rate and the link quality of the POS machine respectively fall into the respective allowable ranges, judging that the POS machine is positioned at an authorized place; the delay, the packet loss rate and the link quality are all represented by numerical values, so that an allowable numerical value range can be obtained, and when the three values respectively fall into the corresponding numerical value ranges, the POS machine is judged to be positioned at the authorized place.
In this embodiment, the allowable range of any one of the delay amount, the packet loss rate or the link quality of the POS machine is determined according to the historical data by the following method: the base station determines the distribution of historical data by taking time as a horizontal axis and a numerical value as a vertical axis; calculating a regression line of the historical data; taking the current time on a time axis, and determining a numerical value corresponding to the regression line and the current time; obtaining a left end point of the allowable range from a value corresponding to the current time on the regression line and a set lower offset coefficient, and obtaining a right end point of the allowable range from a value corresponding to the current time on the regression line and a set upper offset coefficient; obtaining an allowable range from the left endpoint and the right endpoint; any one of delay, packet loss rate or link quality is taken as the average value of each test, so that a series of discrete points can be obtained, linear regression fitting can be carried out on the discrete points, and a corresponding value can be obtained from the current time after fitting. In this embodiment, the upper offset coefficient and the lower offset data may be identical, and typically take a range between 0.2 and 0.4, for example, the upper offset coefficient and the lower offset data each take 0.3, and the value obtained is n, and the allowable range is (0.7 n,1.3 n).
As an alternative embodiment, for the second check, the testing the link quality of the POS machine using the random data in conjunction with the base station includes:
acquiring a first data packet sent by the base station;
and adding the working process data corresponding to the working process information to the head data segment and/or the tail data segment of the first data packet to obtain a second data packet.
And returning the second data packet to the base station, so that the base station determines the delay amount and the packet loss rate of the POS machine according to the data contained in the sent first data packet and the non-added data in the returned second data packet, and determines the link quality of the POS machine according to the delay amount and the packet loss rate.
In this embodiment, the steps of the method for testing the link quality of the POS machine in the second verification process are the same as those of the first verification, except that the transmitted data have a certain difference, and the working process data are added into the data transmitted in the second verification; the step of adding the work process data to the head data segment and/or the tail data segment of the first data packet comprises the following steps: converting the work process data into a binary format, calculating the length of the work process data, and recording the length in a variable data_len; reserving a space (16 bytes) with a fixed length in a head data section and/or a tail data section of the first data packet, wherein the space is used for storing work process data and related information, and the information can comprise task names, progress completion degrees and the like, and is specific to an application scene; and converting the data_len into a binary format, filling the binary format into a fixed length, adding the binary format into the reserved space to form a second data packet, and transmitting the whole second data packet to the target server.
According to the embodiment, the working process data corresponding to the working process information is combined with the first data packet for the identity verification of the POS machine, the step of returning the two data information is reduced to one time by two times originally, and the energy consumption of the POS machine is greatly reduced due to the fact that the energy consumption generated by each data transmission is large.
