Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
The following describes a management method and apparatus of a controller and an electronic device according to an embodiment of the present invention with reference to the accompanying drawings.
Fig. 1 is a flow chart of a method of managing a controller according to an embodiment of the present disclosure. As shown in fig. 1, the management method of the controller provided in this embodiment includes the following steps:
s101, identifying whether the controller is in a power-on state.
Generally, a current detection circuit is arranged in the controller, and can be used for detecting the current in the controller, and when the current value in the controller exceeds a preset current value, the controller can be determined to be in a power-on state; and when the current value in the controller is detected not to exceed the preset current value, determining that the controller is not in a power-on state.
S102, detecting whether a first application program to be executed is valid or not under the condition that the controller is in a power-on state.
Specifically, when the controller is in a power-on state, the controller operates the application program set in the controller according to the preset operation logic. Wherein, before running the application program, in order to ensure that the controller can run normally, it is optional to detect whether the application program in the controller is valid. In this embodiment, it is necessary to detect whether the first application to be executed is valid. When the first application program is invalid, the controller cannot normally run, and step S103 is executed; and when the first application program is valid, the controller can operate normally, and step S104 is executed.
Alternatively, when detecting whether the first application is valid, the check value of the valid flag bit of the first application may be used to determine whether the first application is valid. As shown in fig. 2, the method comprises the following steps:
s201, acquiring a check value of an effective zone bit of the first application program based on a redundancy check algorithm.
Specifically, a redundancy check algorithm is used for calculating file contents in the first application program, so that a check value of a valid flag bit of the first application program is obtained. The redundancy check algorithm is a cyclic redundancy algorithm (CRC), a message digest algorithm (Message Digest Algorithm MD 5) or a secure hash algorithm (Secure Hash Algorithm 1, SHA 1).
S202, determining whether the first application program is effective according to the check value.
Specifically, a check value of an effective flag bit of the first application program is obtained, and the check value is compared with a preset check value. When the two are matched, determining that the first application program is effective; when the two do not match, then the first application is determined to be invalid.
S103, if the first application program is invalid, the first application program is forbidden to run, and an exception handling mode is entered.
Specifically, when the first application is invalid, the controller will not operate normally, and therefore, at this time, the first application is prohibited from operating and enters an exception handling mode.
Optionally, as shown in fig. 3, the exception handling mode includes the steps of:
s301, identifying whether a brushing instruction of the first application program is received.
Specifically, when the first application is invalid, in order for the controller to operate normally, it is necessary to brush the first application. Therefore, the control instruction issued by the staff member can be detected, and when the brushing instruction of the first application program issued by the staff member is received, the first application program can be brushed, namely, the step S302 is executed; when the instruction for writing the first application program issued by the staff member is not received, in order to enable the controller to meet the basic requirement of the staff member, the pre-stored second application program may be executed, that is, step S303 is executed.
S302, the first application program is refreshed.
Specifically, when a swiping instruction is received, the first application program is swished. When the first application program is refreshed, the first application program can be obtained first, for example, the refreshing program can be downloaded from a network server, and then the first application program is updated by using the refreshing program.
Alternatively, when the first application program is updated with the brushware, the valid flag bit of the brushware may be written first and then written into the controller.
S303, executing a pre-stored second application program.
Specifically, when the brushing instruction is not received, if the invalid first application program continues to run, the controller cannot meet the use requirement of the staff. Therefore, in order to enable the controller to meet the basic use requirement of the staff, in this embodiment, the second application program for implementing part of the functions of the first application program is stored in the controller in advance, and the storage space required by the second application program is smaller than the storage space of the first application program. In this embodiment, since the storage space required by the second application is smaller than that of the first application, this significantly reduces the manufacturing cost of the controller relative to the way the first application is backed up.
S104, if the first application program is valid, the first application program is operated.
Specifically, when the first application is active, the controller will be able to run normally, and therefore, at this time, the first application is run.
Optionally, before the first application program is executed, a control instruction issued by the staff member may be detected, so that the controller can be executed according to the intention of the staff member. When the controller instruction of the controller is detected and determined not to be received, the fact that the controller is not required to be brushed by a worker is indicated, and at the moment, the first application program is normally operated; and when the controller command of the controller is detected and determined to be received, indicating that the controller needs to be refreshed by the staff, entering a refreshing mode by the controller at the moment, and refreshing the first application program.
In summary, in the management method of the controller provided in the embodiment, when the controller is in the power-on state, whether the first application to be executed is valid is detected, the first application is operated when the first application is valid, and the first application is prohibited from being operated when the first application is invalid, and meanwhile, the controller enters an exception handling mode, so that the controller is prevented from operating the invalid application, and the stability of the controller is improved.
In some embodiments, the valid flag of the first application and the first application may also be erased before the first application's brush is obtained to ensure that the first application can be refreshed. As shown in fig. 4, the method comprises the following steps:
s401, receiving an erasing instruction for erasing the first application program.
Specifically, the erasing command may be generated by the controller itself, or may be issued by a worker, and may be specifically determined according to the actual situation, which is not limited herein. When the erasure instruction is generated by the controller itself, it is determined that the erasure instruction is received; when the erasure command is issued by a worker, the erasure command can be determined to be received when a signal of the erasure command is transmitted to the controller.
S402, erasing the valid mark of the first application program and the first application program.
Specifically, after receiving an erase command for erasing the first application program, the valid flag of the first application program and the first application program can be erased.
Optionally, in order to ensure that the effective flag of the first application program after being written is correct, the effective flag of the first application program may be erased first, and then the first application program may be erased.
In some embodiments, before the first application is flushed, it may also be determined whether the controller currently satisfies a flush condition to ensure that the flush can be completed successfully. When the power supply voltage of the controller is detected to be larger than a preset voltage threshold value and the moving speed of the carrier of the controller is detected to be smaller than a preset speed threshold value, the controller is determined to meet the brushing condition. For example, when the controller is disposed on the vehicle, the controller is allowed to brush the first application program only when the power supply voltage of the controller is required to be greater than a preset voltage threshold and the running speed of the vehicle is less than a preset speed threshold.
In some embodiments, when the first application is updated with the brushware, the brushware may also be checked to ensure that the brushware was successful. As shown in fig. 5, the method comprises the following steps:
s501, respectively acquiring a check value of an effective zone bit of a first application program and a check value of an effective zone bit of a refreshing program based on a redundancy check algorithm.
Specifically, a redundancy check algorithm is used for calculating file contents in the first application program, so that a check value of a valid flag bit of the first application program is obtained. And calculating the file content in the refreshing program by using a redundancy check algorithm, so as to obtain the check value of the effective zone bit of the refreshing program.
S502, judging whether the check value of the effective zone bit of the first application program is matched with the check value of the effective zone bit of the writing program.
Specifically, the check value of the valid flag bit of the first application program is compared with the check value of the valid flag bit of the writing program, and whether the two are matched can be determined. When the two are matched, the brushing program is correct, and the first application program can be successfully updated by using the brushing program, and step S503 is executed; when the two do not match, the brusher is erroneous, and the first application cannot be updated with the brusher, step S504 is performed.
S503, updating the first application program by using the brushing program.
Specifically, when the check value of the valid flag bit of the first application program matches the check value of the valid flag bit of the brushwrite program, the first application program is updated with the brushwrite program.
S504, re-entering an exception handling mode.
Specifically, when the check value of the valid flag bit of the first application program does not match the check value of the valid flag bit of the brushwrite program, the exception handling mode is re-entered to reacquire the brushwrite program.
In order to facilitate understanding, the management method of the controller provided in this embodiment is explained below. As shown in fig. 6, the control flow of the management method of the controller in the present embodiment includes the following steps:
s601, identifying whether the controller is in a power-on state.
S602, detecting whether a first application program to be executed is valid or not under the condition that the controller is in a power-on state. Wherein, if the first application is valid, steps S603-S609 are performed; if the first application is not valid, steps S610-S613 are performed.
