[0042] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] See also Figure 1-Figure 2 , the first aspect of the present invention provides a system for testing the signal strength of a CAT1 device, comprising: testing software, a server, an mqtt platform and a CAT1 device;

[0044] Test software: used to preset the number of cycles and send the imei number of the CAT1 device to be tested to the server in a cycle;

[0045] Server: used to create and cache a unique ID; generate a test command based on the unique ID and IMEI number, and mark the time when the test command was generated as the first time; forward the test command to the CAT1 device through the MQTT platform;

[0046] Receive the reply command sent by the CAT1 device and parse it to obtain a response ID; mark the time of parsing the reply command as the second time; count the number of packet losses according to the response result of the reply command and calculate the packet loss rate based on the total number of test commands issued; wherein the response result includes received and lost packets;

[0047] Obtain the response time and update the current number of cycles based on the consistency between the response ID and the unique ID; obtain the signal strength based on several response times and packet loss rates; wherein the signal strength includes weak signals and strong signals;

[0048] MQTT platform: used to receive the test command sent by the server and forward the test command to the CAT1 device; and, receive the reply command of the CAT1 device and forward the reply command to the server;

[0049] CAT1 device: used to parse the test command to get the reply command, and forward the reply command to the server through the MQTT platform.

[0050] Exemplarily, the preset number of cycles in the test software is set to 4 times, and the IMEI number of the CAT1 device is HCL9000456DATET91000D368.

[0051] In the first cycle, the server creates a unique ID of 1001 and caches it. It generates a test command HCL9000456DATET91000D368 / 1001 based on the unique ID (1001) and the IMEI number (HCL9000456DATET91000D368), and marks the time of generating the test command as the first time d1 (2019-08-1810:33:13).

[0052] Forward the test command to the CAT1 device through the MQTT platform;

[0053] Count the number of packet losses based on the server's response to the reply command;

[0054] The server parses the reply command to obtain a unique id of 1001, marks the unique id obtained by the parsing as the response id (1001), and marks the current time with the second time d2 (2019-08-18 10:35:13);

[0055] Since the response id (1001) is consistent with the unique id (1001) cached by the server, the response time is T1=120s obtained by subtracting the first time d1 from the second time d2, and the current number of cycles is increased by one and updated, and the current number of cycles is 1;

[0056] Since the current loop count is 1, which is less than the preset loop count of 4, the server removes the cached unique ID (1001) and executes the second loop;

[0057] In the second loop, the server creates a unique ID of 1002 and caches it. It generates a test command HCL9000456DATET91000D368 / 1002 based on the unique ID (1002) and the IMEI number (HCL9000456DATET91000D368), and marks the time of generating the test command as the first time d3 (2019-08-1810:35:13).

[0058] Forward the test command to the CAT1 device through the MQTT platform;

[0059] The CAT1 device parses the test command (HCL9000456DATET91000D368 / 1002) and obtains the reply command (HCL9000456DATET91000D368 / 1002), and forwards the reply command to the server through the MQTT platform;

[0060] Count the number of packet losses based on the server's response to the reply command;

[0061] The server parses the reply command to obtain a unique id of 1002, marks the unique id obtained by the parsing as the response id (1002), and marks the current time with the second time d4 (2019-08-18 10:37:15);

[0062] Since the response id (1002) is consistent with the unique id (1002) cached by the server, the response time is obtained by subtracting the first time d3 from the second time d4, which is T2=122s. The current number of loops is increased by one and updated. The current number of loops is 2.

[0063] Since the current loop count is 2, which is less than the preset loop count of 4, the server removes the cached unique ID (1002) and executes the third loop;

[0064] In the third loop, the server creates a unique ID of 1003 and caches it. It generates a test command HCL9000456DATET91000D368 / 1003 based on the unique ID (1003) and the IMEI number (HCL9000456DATET91000D368), and marks the time of generating the test command as the first time d5 (2019-08-1810:38:10).

[0065] Forward the test command to the CAT1 device through the MQTT platform;

[0066] The CAT1 device parses the test command (HCL9000456DATET91000D368 / 1003) and obtains the reply command (HCL9000456DATET91000D368 / 1003), and forwards the reply command to the server through the MQTT platform;

[0067] Count the number of packet losses based on the server's response to the reply command;

[0068] The server parses the reply command to obtain a unique ID of 1002, marks the unique ID obtained by parsing as the response ID (1003), and marks the current time with the second time d6 (2019-08-18 10:39:40);

[0069] Since the response id (1003) is consistent with the unique id (1003) cached by the server, the response time is obtained by subtracting the first time d5 from the second time d6, which is T3=90s. The current number of cycles is increased by one and updated. The current number of cycles is 3.

[0070] Since the current loop count is 3, which is less than the preset loop count of 4, the server removes the cached unique ID (1003) and executes the fourth loop;

[0071] In the fourth loop, the server creates a unique ID of 1004 and caches it. It generates a test command HCL9000456DATET91000D368 / 1004 based on the unique ID (1004) and the IMEI number (HCL9000456DATET91000D368), and marks the time of generating the test command as the first time d5 (2019-08-1810:40:10).

[0072] Forward the test command to the CAT1 device through the MQTT platform;

[0073] The CAT1 device parses the test command (HCL9000456DATET91000D368 / 1003) and obtains the reply command (HCL9000456DATET91000D368 / 1003), and forwards the reply command to the server through the MQTT platform;

[0074] Assuming that the server receives the test command replied by the CAT1 device at this time, it will mark the response result as packet loss, and increase the number of packet losses by one and update it.

[0075] In this embodiment, the mqtt platform is connected to the server and the CAT1 device through communication and / or electrical connection respectively; the test software is connected to the server through communication and / or electrical connection.

[0076] In this embodiment, the server creates a unique ID in each cycle, and the unique IDs created in each cycle are different.

[0077] In this embodiment, after counting the number of packet losses according to the response result of the reply command, the packet loss rate is calculated based on the total number of test commands issued, including:

[0078] Determine whether the server receives a reply command; if yes, mark the response result as received; if no, mark the response result as packet loss, and increase the number of packet losses by one and update;

[0079] Extract the number of packet losses and the total number of test commands sent by the server; through the formula Calculate the packet loss rate DBL; where DBC is the number of packet losses and m is the total number of test commands sent by the server.

[0080] Exemplarily, the number of packet loss times DBC=1 is set, and the total number of test commands sent by the server is m=4; the packet loss rate DBL=25% is calculated by the formula.

[0081] In this embodiment, the response time is obtained and the current cycle number is updated according to the consistency between the response ID and the unique ID, including:

[0082] Determine whether the response ID is consistent with the unique ID cached by the server; if yes, subtract the first time from the second time to get the response time, add one to the current number of loops and update; if no, terminate the current loop and reset the number of loops in the test software.

[0083] In this embodiment, the signal strength is obtained based on several response times and packet loss rates, including:

[0084] Extract several response times and packet loss rates;

[0085] Calculate an average response time based on several response times;

[0086] It is determined whether the average response time is less than the response time threshold and the packet loss rate is less than the packet loss threshold; if yes, the signal strength is marked as a strong signal; if no, the signal strength is marked as a weak signal.

[0087] Exemplarily, the average response time is set to 110.6s, the packet loss rate is 25%, the response time threshold is 115s, and the packet loss threshold is 5%; since the average response time is less than the response time threshold and the packet loss rate is greater than the packet loss threshold, the signal strength is marked as a weak signal.

[0088] In this embodiment, the average response time is calculated based on several response times, including:

[0089] By formula Calculate the average response time T of CAT1 devices avg ; Among them, T i is the response time of the CAT1 device in the i-th cycle, i=1, 2, ..., n, and n is the total number of times the server receives the reply command.

[0090] For example, the response time of the CAT1 device in the first cycle is set to T1=120s, the response time of the CAT1 device in the second cycle is set to T2=122s, and the response time of the CAT1 device in the third cycle is set to T3=90s; the average response time of the CAT1 device is calculated by the formula T avg ≈110.67s.

[0091] A second aspect of the present invention provides a method for controlling the strength of a CAT1 device test signal, comprising:

[0092] S1: The test software presets the number of cycles and sends the imei number of the CAT1 device to be tested to the server in a cycle;

[0093] S2: The server creates and caches a unique id;

[0094] S3: Generate a test command based on the unique ID and IMEI number, and mark the time when the test command is generated as the first time;

[0095] S4: The server forwards the test command to the CAT1 device through the MQTT platform;

[0098] S7: The server receives the reply command sent by the CAT1 device and parses it to obtain a response ID; and marks the time of parsing the reply command as the second time;

[0099] S8: Obtain the response time and update the current number of cycles based on the consistency between the response ID and the unique ID;

[0100] S9: Determine whether the current number of loops is equal to the preset number of loops; if yes, jump to S10; if no, the server removes the cached unique ID and jumps to S2;

[0101] S10: Acquire signal strength based on a number of response times and packet loss rates.
