Description

Technical Field

[0001] This invention belongs to the technical field of work log data management for optoelectronic reconnaissance payload control commands, operating status, etc., and specifically relates to a method for managing work log data of optoelectronic reconnaissance payloads. Background Technology

[0002] Electro-optical reconnaissance payloads are one of the important mission payloads of unmanned helicopters. They are used to maintain a high-precision and stable line of sight under changes in the aircraft's attitude and flight vibrations, and to provide ground combat personnel with stable and clear external infrared, near-infrared and visible light scene video. They can detect, identify and target battlefield targets under day / night conditions. With the addition of manual control, target acquisition and automatic video tracking functions, they can complete land and sea search and rescue support work.

[0003] Currently, the optoelectronic reconnaissance payload cannot record and collect operational status data reported by each optoelectronic sensor and electronic unit in real time during power-on operation; it cannot record and collect control command data sent to each optoelectronic sensor and electronic unit, as well as communication data from each optoelectronic sensor and electronic unit, in real time; and it cannot record and calculate the response time between control commands and operational status online in real time. Therefore, the optoelectronic reconnaissance payload cannot detect and monitor the operational status of each optoelectronic sensor and electronic unit, or the data transmission status of each communication interface in real time during operation. This results in the inability to specifically detect or monitor any abnormalities in a particular optoelectronic sensor or electronic unit during routine operation or ground maintenance. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] The technical problem to be solved by the present invention is to provide a method for managing the working log data of an optoelectronic reconnaissance payload, so as to realize the functions of online detection, monitoring and management of working log data.

[0006] (II) Technical Solution

[0007] To address the aforementioned technical problems, this invention provides a method for managing the operational log data of an optoelectronic reconnaissance payload, comprising the following steps:

[0008] The optoelectronic mission station can detect and record the control data information transmitted by the optoelectronic reconnaissance payload in real time, and set the data attribute fields such as the name of the control data, transmission time, transmission frequency, and transmission timestamp;

[0009] The optoelectronic task station determines whether the control data is a normal control data record based on the work log data mapping table. If not, it manages the data according to a specific data record management method, inserts it into the work log database, sets the storage record identifier to storage end, and ends the current work log data management. Otherwise, it manages the data as a normal control data record, inserts it into the work log database, and sets the storage record identifier to storage start.

[0010] The optoelectronic mission seat periodically detects operational status data received from the optoelectronic reconnaissance payload; if operational status data is detected, the name, reception time, reception frequency, and reception timestamp of the operational status data are set.

[0011] The optoelectronic task station determines whether the operating status data is a normal status data record based on the work log data mapping table. If not, it manages it according to a specific data record management method, inserts it into the work log database, sets the storage record identifier to storage end, and ends the current work log data management. Otherwise, it manages it as a normal status data record, searches the work log database for the corresponding control data record based on the name of the operating status data, and if the search is successful, merges the retrieved control data record with the current operating status data record into one data record, calculates the response time, sets the association to full-work communication, sets the storage record identifier to storage end, and updates the data record in the work log database, ending the current work log data management. If the search fails, it sets the storage record identifier to storage suspension. If the storage record identifier corresponding to the data record with the storage record identifier of storage suspension is not reset to storage end within the specified time, the response time is set to the preset communication timeout time, the association is set to communication abnormality, and it is managed according to the communication abnormality management method.

[0012] Preferably, the specific data record management method is as follows: The photoelectric task station receives the specific data record at this time and judges it according to the work log data mapping table. If it is a specific control data record, the name of the running status data is set to empty, the receiving time, receiving frequency, receiving timestamp, and response time are all 0, the association relationship is simplex communication, the storage record identifier is set to storage end, and this data record is inserted into the work log management database; if it is a specific status data record, the name of the control data is set to empty, the sending time, sending frequency, sending timestamp, and response time are all 0, the association relationship is simplex communication, the storage record identifier is set to storage end, and this data record is inserted into the work log management database.

[0013] Preferably, the communication anomaly management method refers to the photoelectric task seat periodically traversing all data records in the work log database, judging the association field of each data record. If storage is suspended, a timer is started to accumulate the count. If the accumulated count is less than or equal to the preset communication timeout, during this period, if the association field of the data record is updated to storage start or storage end, the timer is turned off, the accumulated count stops, the data attributes of the data record are set, the response time is calculated, the association is set, and the storage record identifier is set. If the accumulated count is greater than the preset communication timeout, the data attributes of the data record are set, the response time is set to the preset communication timeout, the association is set to communication anomaly, and the storage record identifier is set to storage end.

[0014] Preferably, after the optoelectronic mission station powers on, if it receives power-on handshake control data from the optoelectronic reconnaissance payload, it immediately replies with handshake response status data. If it does not receive power-on handshake status data from the optoelectronic reconnaissance payload, it periodically sends power-on handshake control commands to the optoelectronic reconnaissance payload, waiting for the payload to reply with handshake response status data. Before determining whether the control data is normal control data recording, the optoelectronic mission station manages the control data according to the synchronous handshake management method. Specifically, the synchronous handshake management method involves the optoelectronic mission station detecting and recording the control data sent by the optoelectronic reconnaissance payload in real time, and then determining whether it is power-on handshake control data sent by the optoelectronic reconnaissance payload. If it is, the station sets the name, reception time, reception frequency, and reception timestamp of the control data, as well as the name and reception time of the status data. The system calculates the response time, sets the association to full-work communication, and sets the storage record identifier to storage end for data attributes such as time interval, receiving frequency, and receiving video stamp. It then inserts this data record into the work log database. If the data is not power-on handshake control information sent by the optoelectronic mission station, it determines whether the control data is a normal control data record. If it is handshake response status data information replied by the optoelectronic reconnaissance payload, it searches the work log database for power-on handshake control data information. If the search is successful, it sets the name, sending time, sending frequency, and sending timestamp of the control data, as well as the name, receiving time, receiving frequency, and receiving video stamp of the status data. It calculates the response time, sets the association to full-work communication, and sets the storage record identifier to storage end. Otherwise, it periodically sets the sending time and sending timestamp, and accumulates the sending frequency until the optoelectronic mission station is powered off.

[0015] The present invention also provides a system for implementing the method.

[0016] (III) Beneficial Effects

[0017] This invention provides a method for managing the operational log data of an optoelectronic reconnaissance payload. This method involves recording control commands and operational status data received and transmitted by the optoelectronic reconnaissance payload during daily operation in a database, performing operations such as insertion, updating, and retrieval. This achieves online detection, monitoring, and management of the operational log data. This solution has the following technical advantages:

[0018] (i) This method can detect the control commands and operating status of the photoelectric reconnaissance payload in real time through the photoelectric mission station, which makes it easier for ground operators to monitor the specific operation of the photoelectric reconnaissance payload, optimizes the monitoring mechanism of the photoelectric reconnaissance payload, and improves the operating efficiency.

[0019] (II) This method realizes the recording, updating and retrieval functions of the working log data of the photoelectric reconnaissance payload in the database, further improving and strengthening the control and management functions of the photoelectric reconnaissance payload, and facilitating the offline detection and monitoring of the photoelectric reconnaissance payload in the later stage.

[0023] Figure 4 This is a logic diagram for the synchronous handshake management of the present invention. Detailed Implementation

[0024] To make the objectives, contents, and advantages of the present invention clearer, the specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0025] like Figure 1 As shown, the specific process of the photoelectric reconnaissance payload operation log data management method provided by the present invention is as follows:

[0026] The optoelectronic mission station can detect and record the control data information transmitted by the optoelectronic reconnaissance payload in real time, and set data attribute fields such as the name, transmission time, transmission frequency, and transmission timestamp of the control data.

[0027] The optoelectronic task station determines whether the control data is a normal control data record based on the work log data mapping table. If not, it manages the data according to a specific data record management method, inserts it into the work log database, sets the storage record identifier to storage end, and ends the current work log data management. Otherwise, it manages the data as a normal control data record, inserts it into the work log database, and sets the storage record identifier to storage start.

[0028] The optoelectronic mission seat periodically detects the operational status data information received from the optoelectronic reconnaissance payload; if operational status data information is detected, data attribute fields such as the name of the operational status data, reception time, reception frequency, and reception timestamp are set.

[0029] The optoelectronic task station determines whether the operating status data is a normal status data record based on the work log data mapping table. If not, it manages it according to a specific data record management method, inserts it into the work log database, sets the storage record identifier to storage end, and ends the current work log data management. Otherwise, it manages it as a normal status data record, retrieves the corresponding control data record in the work log database based on the name of the operating status data, and if the retrieval is successful, merges the retrieved control data record with the current operating status data record into one data record, calculates the response time (i.e., the difference between the sending timestamp and the receiving timestamp), sets the association to full-work communication, sets the storage record identifier to storage end, and updates this data record in the work log database, ending the current work log data management. If the retrieval fails, it sets the storage record identifier to storage suspension. If the storage record identifier corresponding to the data record with the storage record identifier of storage suspension is not reset to storage end within the specified time, the response time is set to the preset communication timeout time, the association is set to communication abnormality, and it is managed according to the communication abnormality management method.

[0030] like Figure 2 As shown, the specific data record management method is divided into two types: the specific control data record management method and the specific operating status data management method. The optoelectronic mission station receives specific data records at this time and judges them according to the work log data mapping table. If it is a specific control data record, the name of the running status data is set to empty, the receiving time, receiving frequency, receiving timestamp, and response time are all 0, the association is simplex communication, the storage record identifier is set to storage end, and this data record is inserted into the work log management database. For example, for a TV brightness adjustment control command, when the optoelectronic reconnaissance payload responds to the TV brightness adjustment control command, it does not report the working status to the optoelectronic mission station. Therefore, this data record only has control data information and no status data information, so it is simplex communication. If it is a specific status data record, the name of the control data is set to empty, the sending time, sending frequency, sending timestamp, and response time are all 0, the association is simplex communication, the storage record identifier is set to storage end, and this data record is inserted into the work log management database. For example, after the thermal imaging cooling is completed, the optoelectronic reconnaissance payload reports the thermal imaging field of view status as large field of view to the optoelectronic mission station. Therefore, this data record only has status data information and no control data information, so it is simplex communication.

[0031] like Figure 3As shown, the communication anomaly management method refers to the photoelectric task seat periodically traversing all data records in the work log database, judging the association field of each data record. If storage is suspended, a timer is started to accumulate the count. If the accumulated count is less than or equal to the preset communication timeout, and during this period, if the association field of the data record is updated to storage start or storage end, the timer is turned off, the accumulated count stops, the data attributes of the data record are set, the response time is calculated, the association is set, and the storage record identifier is set, etc. If the accumulated count is greater than the preset communication timeout, the data attributes of the data record are set, the response time is set to the preset communication timeout, the association is set to communication anomaly, and the storage record identifier is set to storage end.

[0032] like Figure 4 As shown, after the optoelectronic mission station powers on, if it receives power-on handshake control data from the optoelectronic reconnaissance payload, it immediately replies with handshake response status data. If it does not receive power-on handshake status data from the optoelectronic reconnaissance payload, it periodically sends power-on handshake control commands to the payload, waiting for a reply. Before determining whether the control data is normal control data, the optoelectronic mission station manages the control data according to the synchronous handshake management method. Specifically, the synchronous handshake management method involves the optoelectronic mission station detecting and recording the control data sent by the optoelectronic reconnaissance payload in real time, then determining whether it is power-on handshake control data from the payload. If it is, the station sets the control data name, reception time, reception frequency, and reception timestamp, as well as the status data name, reception time, reception frequency, and reception timestamp, calculates the response time (the difference between the sending and receiving timestamps), sets the association to full-work communication, sets the storage record identifier to storage end, and inserts the data record into the work log. According to the database; if it is not the power-on handshake control data information sent by the optoelectronic mission station, then determine whether the control data is a normal control data record; if it is the handshake response status data information replied by the optoelectronic reconnaissance payload, then search for the power-on handshake control data information in the work log database. If the search is successful, set the data attributes such as the name, sending time, sending frequency, and sending timestamp of the control data, as well as the name, receiving time, receiving frequency, and receiving video stamp of the status data, calculate the response time (the difference between the sending timestamp and the receiving timestamp), set the association relationship to full-work communication, and set the storage record identifier to storage end; otherwise, periodically set the sending time and sending timestamp, and accumulate and count the sending frequency until the optoelectronic mission station is powered off.

[0033] As can be seen, this invention can record and collect control data records such as control commands, transmission timestamps, and transmission frequencies from the electro-optical reconnaissance payload online in real time, and insert or update these control data records in the work log database. Simultaneously, it receives status data records such as operating status, reception timestamps, and reception frequencies from the electro-optical reconnaissance payload to the electro-optical mission position. Based on the operating status data name field, it retrieves the associated control data record in the work log database. If the retrieval is successful, it calculates the response time between sending the control command and receiving the operating status, and synchronously updates the corresponding operating status data record in the database on a workday basis. If phenomena such as unresponsive control commands or abnormal reporting of operating status occur during daily work or ground maintenance, the specific response status of the entire data link can be investigated step by step, realizing functions such as real-time detection, monitoring, and management of work log data.

[0034] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
