Description
Technical Field
The invention relates to design of airborne equipment, in particular to a position identification method of airborne equipment.
Background
When the left and right interchangeable airborne equipment is initially powered on, the air state and the ground state are generally not distinguished, and the position identification signal is collected once. If the position identification signal is acquired, the left side or the right side of the airplane where the airborne equipment is located is judged through the position identification signal, and the airborne equipment executes the function of the corresponding side. If airborne equipment collection interface or position identification circuit after breaking down, airborne equipment can't gather position identification signal, then can't discern the identity by oneself, and the initialization can't be accomplished, leads to the equipment unable work. This situation would only affect the dispatch of the aircraft if it occurs on the ground, but could affect the safety of the system or the aircraft if it occurs in the air.
Disclosure of Invention
In order to solve the technical problem, the onboard equipment position identification method provided by the application can identify the identity of the onboard equipment after the onboard equipment position identification signal fails.
The application provides a method for identifying the position of airborne equipment, which comprises the following steps:
the wheel load state of the airplane is the ground, and when the airborne equipment is initially electrified, the position identification signal is collected for the first time;
if the position identification signal is acquired, judging the position identification state of the airborne equipment through the position identification signal, enabling the airborne equipment to normally work, and storing the position identification state by using a memory;
if the position identification signal cannot be acquired, judging that the fault state of the airborne equipment is a fault, enabling the airborne equipment not to work, and storing the fault state of the equipment by using a memory;
when the wheel load state of the airplane is in the air and the onboard equipment is electrified again, acquiring the position identification signal for the second time;
and if the position identification signal cannot be acquired, reading the position identification state from the memory, taking the position identification state as the current position of the airborne equipment, and enabling the airborne equipment to normally work.
Specifically, the position recognition state includes a left side and a right side.
Specifically, the onboard equipment fault state comprises normal and fault.
Specifically, after the position identification state is used as the current position of the airborne equipment and the airborne equipment enters normal operation, the method further comprises the following steps: and recording the fault information in a memory for a maintenance worker to call for maintenance.
Specifically, the memory includes a nonvolatile memory, a hard disk, and a flash.
In particular, the method is applied to an airborne equipment position identification system.
Specifically, the airborne equipment position identification system comprises a central processing unit and a memory.
In summary, the present application provides a method for identifying a location of an onboard device, which does not rely on a location identification signal alone to determine the location during the location identification of the device, and uses a memory to store the previously determined location identification status information. And reading the position identification state stored in the memory as the current identification position of the equipment once the position information of the equipment which cannot be judged according to the collected position identification signal appears. Even if the position identification fails, the equipment can also work normally, and the use safety of the equipment is greatly improved.

wherein: 1-airborne equipment, 2-central processing unit, 3-internal bus and 4-memory.
Detailed Description
The following further describes the embodiments of the present invention with reference to the drawings.
The airborne equipment (1) comprises a central processing unit (2), an internal bus (3) and a nonvolatile memory (4). The central processing unit (2) collects the position identification signal 1, the position identification signal 2 and the wheel-mounted signal, and comprehensively judges to obtain a position identification state. The central processing unit (2) is connected with the nonvolatile memory (4) through the internal bus (3) and stores or reads the position identification state.
The wheel load state of the airplane is the ground, and when the airborne equipment is initially powered on, the central processing unit (2) collects the position identification signal 1 and the position identification signal 2 for the first time;
if the acquisition value of the position identification signal 1 is 0 and the acquisition value of the position identification signal 2 is 1, the central processing unit (2) judges that the position of the airborne equipment is the left side, executes the relevant function of the left side, sets the value of the position identification state as the left side, and stores the value into the nonvolatile memory (4) through the built-in bus (3). If the acquisition value of the position identification signal 1 is 1 and the acquisition value of the position identification signal 2 is 0, the central processing unit (2) judges that the position of the airborne equipment is the right side, executes the related function of the right side, sets the value of the position identification state to be the right side, and stores the value into the nonvolatile memory (4) through the built-in bus (3). If the collected position identification signal value is not the two conditions, the central processing unit (2) judges that the equipment fault state is a fault, the airborne equipment does not work, the value of the equipment fault state is set to be a fault, and the fault is stored in the nonvolatile memory (4) through the internal bus (3) and is called by maintenance personnel.
The wheel load state of the airplane is in the air, and when the onboard equipment is powered on again, the central processing unit (2) collects the position identification signal 1 and the position identification signal 2 for the second time;
if the acquisition value of the position identification signal 1 is 0 and the acquisition value of the position identification signal 2 is 1, the central processing unit (2) judges that the position of the airborne equipment is the left side, executes the relevant function of the left side, sets the value of the position identification state as the left side, and stores the value into the nonvolatile memory (4) through the built-in bus (3). If the acquisition value of the position identification signal 1 is 1 and the acquisition value of the position identification signal 2 is 0, the central processing unit (2) judges that the position of the airborne equipment is the right side, executes the related function of the right side, sets the value of the position identification state to be the right side, and stores the value into the nonvolatile memory (4) through the built-in bus (3). If the collected position identification signal value is not the two conditions, the central processing unit (2) reads the position identification state of the nonvolatile memory (4) through the internal bus (3), judges the position of the airborne equipment and executes corresponding functions.
