It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a schematic flowchart of an over-the-air upgrade method according to an embodiment of the present application. As shown in fig. 1, the over-the-air upgrade method is an upgrade method capable of dynamic adjustment, and specifically includes the following steps:
step 100: and receiving an over-the-air upgrade package.
An Over-the-Air Technology (OTA) is a Technology for implementing dynamic downloading, deletion, and updating of a service menu in a SIM card in a mobile phone terminal or server (on-line) manner, so that a user obtains a data value added service (abbreviated as OTA service) of a personalized information service, and remotely manages SIM card data and applications through an Air interface of mobile communication; the over-the-air upgrade package is an upgrade data package used for a control system, such as a display or a control module in a controller, for controlling crane equipment and upgrading versions. The over-the-air upgrading packet is sent to the equipment end by the remote management platform end and received by the vehicle-mounted communication part of the equipment end, so that the vehicle-mounted communication part can upgrade the object to be upgraded by using the over-the-air upgrading packet.
Step 200: and transmitting the over-the-air upgrade package to the upgrade object at a first preset speed and a first preset priority.
The first preset rate is a default rate for transmitting the over-the-air download upgrade package to an upgrade object after the over-the-air download upgrade package is received by the vehicle-mounted communication component, and the rate is a transmission rate which can enable all other data of the whole vehicle to be interacted normally under the condition that the safety of the whole vehicle and all equipment states of the whole vehicle are not affected; the first preset priority is the default priority of the transmission of the over-the-air upgrade package to the upgrade object, and the transmission priority of the upgrade package corresponding to the first priority is smaller than or equal to the transmission priority of other data of the equipment.
Step 300: status information of the device is obtained.
The state information of the equipment refers to the power-on state, the power-off state, the operation state, the non-operation state, the safety state, the non-safety state and the like of the current crane, and because the service conditions of the bus bandwidth of the crane in different states are different, the state information of the equipment is obtained on the premise that the transmission rate of the over-the-air download upgrade package is adjusted according to the state of the equipment.
Step 400: and adjusting the transmission rate and the transmission priority of the over-the-air upgrade package according to the state information of the equipment.
It can be easily known that when the crane is in an emergency and non-safe state, the crane should be processed at the first time, rather than the version upgrade of the control component, in addition, the use conditions of the bus bandwidth are different in the working state and the non-working state of the crane, the data interaction between each control component and the execution mechanism is more frequent and more important in the working state, the interaction of the data is mainly used at the moment, but is opposite in the non-working state, the interaction of other data is unnecessary, the transmission rate of the over-the-air download upgrade package can be properly increased, and the transmission priority is correspondingly adjusted, so that the purpose of reasonably and fully utilizing the bus bandwidth is achieved, the time consumption and the tedious problems caused by the unconditional upgrade rate limitation are saved, and the time cost is saved.
The over-the-air upgrading method comprises the steps of receiving an over-the-air upgrading package; transmitting an over-the-air upgrade package to an upgrade object at a first preset speed and a first preset priority; acquiring state information of equipment; and adjusting the transmission rate and the transmission priority of the over-the-air upgrade package according to the state information of the equipment. The over-the-air upgrading method monitors the current state of the equipment, and meanwhile, the transmission rate and the transmission priority of the over-the-air upgrading packet are correspondingly adjusted according to different states of the equipment, so that the upgrading rate of the equipment is reasonably improved in a safe and non-operation state, the bus bandwidth is fully and effectively utilized, the tedious probability of upgrading the upgrading object is reduced, and the time cost is saved.
In a possible implementation manner, fig. 2 is a schematic flowchart of an over-the-air upgrade method according to another embodiment of the present application. As shown in fig. 2, the status information of the device includes, but is not limited to, an operating status, a non-operating status, and a non-secure status. Thus, step 400 may further comprise the steps of:
step 410: and when the state information of the equipment is in a non-working state, adjusting the first preset rate to a second preset rate, and adjusting the first preset priority to the second preset priority.
The equipment is in a working state, namely the crane is in an operating state; the non-working state of the equipment is the state that the crane is electrified but does not work; the non-safety state refers to a state that the crane has operation risks due to the fact that the crane cannot carry out antigen, such as overload operation and the like; the second preset rate is higher than the first preset rate, and the second preset rate is the highest allowable transmission rate under the condition of not influencing the safety of the whole vehicle, the transmission of control commands and the normal interaction of related working condition data with strong real-time performance; the second predetermined priority corresponds to a priority higher than the priority of other data transmissions on the device, but lower than the priority of device control command transmissions, transmissions of related data relating to device security and operational state switching. When the equipment is in a non-working state, the bus bandwidth of the equipment occupies less, the transmission rate and the transmission priority of the vehicle-mounted communication part for transmitting the over-the-air download upgrade package to the upgrade object are improved, the basic operation and safety guarantee of the equipment are not affected, the upgrade rate of the upgrade object can be improved, and time is saved.
Specifically, fig. 3 is a schematic flow chart of an over-the-air upgrade method according to another embodiment of the present application. As shown in fig. 3, step 410 may further include the following steps:
step 4101: and when the state information of the equipment is in a non-working state, adjusting the first preset rate to the intermediate rate in the first period, and adjusting the intermediate rate to the second preset rate in the second period.
The intermediate rate is the intermediate rate of the first preset rate and the second preset rate, and the period is equal to the duration of the period. When the equipment is in a non-working state, the transmission rate of the upgrading package downloaded to the air periodically or in stages is improved, so that the equipment is safer and more reliable, and the probability that the equipment cannot timely cope with emergency due to too fast speed improvement is reduced.
Step 4102: and in a third period, adjusting the first preset priority to the second preset priority.
In steps 4101 and 4102, the first period, the second period, and the third period are equal in duration. The transmission rate is increased to the maximum allowable rate, and then the priority is increased to the sitting-high allowable priority, so that the adjustment process of the transmission rate of the over-the-air upgrade package is more controllable and safer. Since the second predetermined priority occupies more bus resources than the first predetermined priority, the second predetermined priority is suddenly increased to the highest level, which may affect the capability of the device to cope with the emergency unsafe condition.
It should be noted that the specific duration of each period is determined according to the specific implementation scenario and the type of the crane, and the adjustment process from the first preset rate to the second preset rate does not have to have two periods, and the adjustment process from the first preset priority to the second preset priority does not have to have only one period. It will be appreciated that the number of cycles experienced by the rate adjustment is inversely proportional to the cycle duration, with longer cycle durations requiring fewer cycles for adjustment. In addition, the durations of the first period, the second period and the third period are generally equal but may not be equal, and the periods of equal duration and the periods of unequal duration can both achieve the purpose of adjusting the transmission rate and the transmission priority in stages, but the periods of equal duration are simpler and more convenient to implement in the application process, and have higher controllability. Therefore, the above description is merely an example for convenience of description, and the specific period duration, the number of periods, and the equality and inequality of the period duration should be determined according to the specific application scenario, and the present application does not further limit the present application.
Optionally, fig. 4 is a schematic flow chart of an over-the-air upgrade method according to another embodiment of the present application. As shown in fig. 4, when the status information of the device is in the working status, step 400 may include the following step 420:
step 420: and when the state information of the equipment is the working state of the equipment, transmitting the over-the-air download upgrade package to the upgrade object at a first preset speed and a first preset priority.
The device is in a working state, that is, the device is working at this time, and at this time, the transmission importance degree of other data is higher, so that more bus bandwidth needs to be occupied. Therefore, in this state, the transmission rate and priority of the over-the-air upgrade package should be kept at the minimum allowable level, that is, when the equipment is in the working state, the adjustment of the transmission rate and the transmission priority is not performed temporarily, so as to avoid affecting the normal operation of the crane and causing other adverse effects.
In another possible implementation manner, fig. 5 is a schematic flowchart of an over-the-air upgrade method according to another embodiment of the present application. As shown in fig. 5, after step 410 or step 420, step 400 may further include the steps of:
step 4301: the method comprises the steps of acquiring state information of equipment in real time, adjusting a first preset rate to a second preset rate and adjusting a first preset priority to a second preset priority when the state information is converted from a working state to a non-working state.
The vehicle-mounted communication part can continuously acquire the state information of the equipment, and correspondingly adjust the transmission rate and the transmission priority when the state of the equipment changes. When the state information is converted from the working state to the non-working state and the transmission of the over-the-air download upgrade package is not completed at the moment, the transmission rate can be periodically increased as described above, and meanwhile, after the rate is adjusted to the highest allowable rate, the transmission priority is continuously increased, so that the transmission efficiency of the over-the-air download upgrade package is effectively improved, the bus bandwidth is fully utilized, and the time is saved.
Or:
step 4302: and when the state information is converted from the non-working state to the working state, adjusting the second preset rate to the first preset rate, and adjusting the second preset priority to the first preset priority.
However, when the over-the-air download upgrade package is already at a highest transmission rate or a highest priority, once the device starts working or starts working, the high rate needs to be directly reduced to an initial default low rate, and the high priority needs to be reduced to an initial default low priority, so that the influence on the crane working is reduced, and the possibility of causing unnecessary economic loss is reduced.
Specifically, as shown in fig. 5, as can be seen from the above, before the upgrade of the upgrade object is completed, the vehicle-mounted communication component may acquire the state of the device in real time, and when the device is in the unsafe state due to the non-antigen being unavailable, the step 400 may further include the following steps:
step 440: and when the state information is that the equipment is in a non-safety state, suspending the transmission of the over-the-air download upgrade package to the upgrade object until the non-safety state of the equipment is converted into a working state or a non-working state, and continuing to transmit the over-the-air download upgrade package to the upgrade object.
When the equipment is in an emergency non-safety state due to natural reasons or artificial reasons, such as an overload state and the like, the upgrading is suspended, and the upgrading is triggered again after the state is relieved, so that the influence of bus bandwidth occupied by the upgrading on the transmission of emergency data or emergency control instructions is reduced, and the probability of upgrading failure and other conditions caused by power-off or restarting of the equipment is reduced.
In a possible implementation manner, fig. 6 is a schematic flowchart of an over-the-air upgrade method according to another embodiment of the present application. As shown in fig. 6, before step 100, the following steps are also included:
step 10: device data for the device is transmitted to the management platform.
The management platform is a remote management platform; the device data is the current parameter data of the device. The vehicle-mounted communication component continuously transmits the equipment data to the remote management platform, so that the remote management platform can judge the working state of the crane, whether the crane is safe or not and the like according to the received equipment parameter data before issuing the over-the-air download upgrade task, and when the management platform end judges that the crane is in a safe upgrade-allowed state, the management platform end can formally issue an over-the-air download upgrade package to the vehicle-mounted communication component, so that the vehicle-mounted communication component can transmit the upgrade package to an upgrade object; and when the management platform side judges that the equipment side is in a non-safety state, suspending the upgrading task until the equipment side is converted into a safety state, and then issuing an over-the-air upgrading packet.
Optionally, as shown in fig. 6, step 100 may further include the following steps:
step 110: and receiving the over-the-air upgrade package, and locally storing the over-the-air upgrade package.
The purpose of the vehicle-mounted communication component for locally storing the over-the-air download upgrade package is to directly obtain the upgrade version from the local part when the upgrade task is restarted after the upgrade task is suspended or the equipment is restarted after power is off, so that the effect of saving the flow is achieved.
Specifically, as shown in fig. 6, after step 400, the over-the-air upgrade method may further include the following steps:
step 500: and deleting the locally stored over-the-air upgrading package after the over-the-air upgrading package is completely transmitted to the upgrading object.
When the over-the-air download upgrading package is completely transmitted to the upgrading object, the upgrading of the upgrading object is completed, and the over-the-air download upgrading package stored locally in the vehicle-mounted communication component can be deleted, so that unnecessary memory waste is reduced.
In one possible implementation, as shown in fig. 6, step 300 may further include:
step 310: device data of a device is acquired.
Step 320: and generating the state information of the equipment according to the equipment data.
The vehicle-mounted communication component can judge the state of the equipment through the equipment data acquired in real time, so that the transmission rate and the transmission priority can be adjusted according to the judgment result.
According to a second aspect of the present application, there is also provided an over-the-air upgrade system.

The over-the-air upgrade system provided by the present application includes a management platform 100 and an in-vehicle communication component 200. The in-vehicle communication component 200 in the over-the-air upgrade system may receive an over-the-air upgrade package; transmitting an over-the-air upgrade package to the upgrade object 300 at a first preset rate and a first preset priority; acquiring state information of equipment; and adjusting the transmission rate and the transmission priority of the over-the-air upgrade package according to the state information of the equipment. The over-the-air upgrading method monitors the current state of the equipment, and meanwhile, the transmission rate and the transmission priority of the over-the-air upgrading packet are correspondingly adjusted according to different states of the equipment, so that the upgrading rate of the equipment is reasonably improved in a safe and non-operation state, the bus bandwidth is fully and effectively utilized, the tedious probability of upgrading the upgrading object 300 is reduced, and the time cost is saved.
