Detailed Description

In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. 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 invention.

Referring to fig. 1, fig. 1 is a flowchart of a communication module switching method according to an embodiment of the present invention, where the method may be applied to an interlock device in a communication system capable of performing both Beidou communication and Iridium communication as shown in fig. 2. Namely, the interlocking device comprises an iridium satellite transceiver module, a Beidou regional short message module, a Beidou global short message module and each functional module shown in fig. 5. Specifically, the interlocking device can be arranged in the civil aircraft IMA shown in fig. 3 or the Beidou equipment shown in fig. 4. The method comprises the following steps:

and S101, acquiring the position of the mobile phone.

The local position, i.e. the current location of the communication device. The corresponding positioning technology can be adopted for positioning according to the specific equipment type of the communication equipment, so that the local position is obtained.

Specifically, if the communication device is a civil aircraft IMA (integrated modular avionics system), the step S101 of obtaining the position of the local aircraft may specifically include:

step one, acquiring positioning data in IMA;

and step two, determining the position of the local computer by using the positioning data.

For convenience of description, the above two steps will be described in combination.

The IMA may acquire the positioning data based on the positioning information acquisition module, and for how the positioning information acquisition module specifically acquires the positioning data, the IMA positioning implementation technology may be specifically referred to, which is not described herein any more. After the positioning data is obtained, the position of the local machine can be determined based on the positioning data. For example, if the positioning data is specifically latitude and longitude, the location of the mobile terminal can be determined directly based on the latitude and longitude.

If the communication device is specifically a beidou device, the step S101 obtains the position of the local device, which may be specifically obtaining the position of the local device by using a beidou positioning device. That is to say, to big dipper equipment, can directly utilize big dipper orientation module and location antenna, directly obtain this local position. In this embodiment, how to specifically position the Beidou positioning module and the positioning antenna in the Beidou positioning device, and then determine the position of the machine, the specific implementation process and method of Beidou positioning can be specifically referred to, and are not repeated here.

After the local position is obtained, the operation of step S102 may be performed.

S102, judging whether the Beidou region short message module is in a radio frequency spectrum control region or not by using the position of the Beidou region short message module.

According to the international frequency use and coordination principle, the satellite communication service frequency (uplink: XX-XX MHz, downlink: XX-XX MHz) used by the short message module in the Beidou region has a lower use priority than the satellite communication system frequency (such as an iridium system) registered earlier due to the later registration time, and is partially overlapped with the iridium (1616-1626.5MHz) frequency. Although frequency compatibility and coordination work is ongoing, international frequency coordination is not currently accomplished with higher priority satellite communication systems. Therefore, the international use of the beidou region short message module cannot cause interference to the satellite communication systems with higher priority, and needs to bear the interference of the other party, namely the beidou region short message module can only be used outside the corresponding radio frequency spectrum control region at present.

That is, the use of the beidou zone short message module is limited to the radio spectrum regulatory region. And the power consumption of the Beidou regional short message module is lower than that of the global regional short message module. Namely, under the condition that the Beidou regional short message module can be used, the Beidou regional short message module needs to be used as much as possible. Therefore, after the local position is obtained, whether the Beidou region short message module can be used or not can be determined, namely whether the local position is located in a radio spectrum regulation region or not can be determined.

Specifically, a radio spectrum control area can be obtained in advance, and then after the position of the machine is obtained, the position of the machine is compared with the radio spectrum control area, so that whether the Beidou regional short message module is currently located in the radio spectrum control area or not can be determined, the Beidou regional short message module cannot be used, and the Beidou regional short message module can be used if the Beidou regional short message module is located outside the radio spectrum control area.

In a specific embodiment of the present invention, the step S103 of determining whether the beidou area short message module is located in the radio spectrum regulation area by using the position of the local computer may specifically include:

step one, obtaining an authorized coverage map of a Beidou region short message module;

step two, inquiring whether the position of the local machine falls into an authorized coverage map;

step three, if not, determining that the mobile terminal is out of the radio spectrum regulated area;

and step four, if yes, determining that the mobile terminal is in the radio spectrum regulated area.

For convenience of description, the above four steps will be described in combination.

In this embodiment, an authorized coverage map corresponding to the beidou regional short message module may be set, and the map may determine a geographical range authorized for the beidou regional short message module. That is, the authorized coverage map may be used to distinguish whether the local location is in a radio frequency regulated area. Specifically, the authorized coverage map may be obtained from a surface device.

Having authorized the coverage map, it can be determined whether the local location is within a radio frequency regulated area. Specifically, if the local location falls within the authorized coverage map, it may be determined to be outside the radio-spectrum regulated area, and otherwise, it may be determined to be inside the radio-spectrum regulated area. It should be noted that the authorized coverage map can be adjusted and changed according to the authorized conditions of the beidou system in each region or country. In order to reduce the storage space occupied by the authorized coverage map, the authorized coverage map can also be stored as a low-resolution map.

And after the judgment result is obtained, executing the subsequent steps according to the specific situation of the judgment result. Specifically, if the determination result is yes, the operation of step S103 is executed; if the judgment result is no, the operation of step S104 is executed.

S103, communication is carried out by utilizing an iridium satellite transceiver module and/or a Beidou global short message module.

And when the determination result is yes, determining that the Beidou regional short message module cannot be used. However, the communication frequency of the Beidou global short message module does not coincide with the communication frequency of the iridium satellite transceiver module, so that the iridium satellite transceiver module can be used alone for communication, the Beidou global short message module can be used alone for communication, and the iridium satellite transceiver module and the Beidou global short message module can be used together for communication.

And S104, under the condition that the iridium satellite transceiver module does not work, the Beidou region short message module is used for communication.

The condition that the iridium satellite transceiver module does not work can be specifically the working clearance of the iridium satellite transceiver module, and can also be the condition corresponding to the fact that the iridium satellite transceiver module is stopped.

Under the condition that the Beidou region short message module can be used, the problem of interference with the iridium satellite receiving and sending module is also required to be considered, so that under the condition that the Beidou region short message module can be used, the Beidou region short message module and the iridium satellite receiving and sending module are not shared.

That is to say, even if the current device is not located in the radio spectrum control area, whether the Beidou area short message module is used for communication or not is determined according to the working condition of the iridium satellite transceiver module. Specifically, when the iridium satellite transceiver module works, the Beidou region short message module is not used, and when the iridium satellite transceiver module does not work, the Beidou region short message module can be used. It should be noted that, because there is no interference problem between the big dipper global short message module and the iridium satellite transceiver module, even if the iridium satellite transceiver module is working, the big dipper global short message module can also be used, that is, the big dipper global short message module and the iridium satellite transceiver module can be shared.

In a specific embodiment of the present invention, priorities may be set for the iridium satellite transceiver module and the beidou region short message module, and the priorities may be changed by the ground operation control center under special circumstances (for example, the iridium satellite transceiver module or the beidou region short message fails, or a new priority is manually set and input). And under the condition that the Beidou region short message module can be used, determining to adopt the Beidou region short message module or the iridium transceiving module for communication based on the specific setting of the priority. Based on different situations of priority setting, the specific implementation of step S104 includes the following two situations:

the first condition is as follows:

if the priority of the iridium satellite transceiver module is higher than that of the Beidou region short message module, the step S104 is to communicate by using the Beidou region short message module under the condition that the iridium satellite transceiver module does not work, and may specifically include:

judging whether an iridium satellite transceiver module works or not;

and step two, if not, the Beidou regional short message module is used for communication.

For convenience of description, the above two steps will be described in combination.

That is to say, when the iridium satellite transceiver module works, the Beidou regional short message module is not used for communication, and when the iridium satellite transceiver module does not work, the Beidou regional short message module is used for communication.

Case two:

if the priority of the iridium satellite transceiver module is lower than that of the Beidou region short message module, the step S104 of communicating by using the Beidou region short message module under the condition that the iridium satellite transceiver module does not work may specifically include: and the iridium satellite receiving and transmitting module is stopped, and the Beidou region short message module is used for communication. That is to say, under the condition that the Beidou region short message module can be used, if the priority of the Beidou region short message is higher than that of the Iridium transceiver module, the Beidou region short message module can be used for communication by directly adopting a mode of deactivating the Iridium transceiver module, so as to avoid the problem of signal interference.

By applying the method provided by the embodiment of the invention, the position of the local computer is obtained; judging whether the Beidou region short message module is located in a radio frequency spectrum control region or not by utilizing the position of the Beidou region short message module; if so, communicating by using an iridium satellite transceiver module and/or a Beidou global short message module; if not, the Beidou region short message module is used for communication under the condition that the iridium satellite transceiving module does not work.

According to the method, the position of a local machine is obtained, and whether a short message module in a Beidou region is located in a radio frequency spectrum control region is determined based on the position of the local machine. If the judgment result is yes, the Beidou regional short message module cannot be used at the moment, and the iridium satellite receiving and transmitting module and the Beidou global short message module can be shared in consideration of the fact that the iridium satellite receiving and transmitting module does not have an interference problem, so that at least one module of the iridium satellite receiving and transmitting module and the Beidou global short message module can be used for communication at the moment. If the judgment result is no, the Beidou regional short message module can be considered to be used at the moment, but the interference problem exists between the Beidou regional short message module and the iridium satellite receiving and sending module, so that the Beidou regional short message module can be used for communication under the condition that the iridium satellite receiving and sending module and the Beidou regional short message module are not shared, namely, the iridium satellite receiving and sending module does not work, and the Beidou regional short message module has lower energy consumption relative to the Beidou global short message module, so that the Beidou regional short message module is used as much as possible, and the communication energy consumption can be reduced. Therefore, in the method, the corresponding communication modules are switched and used under different conditions, so that the problem of interference between the iridium satellite transceiver module and the Beidou region short message module can be effectively solved, and the communication energy consumption can be reduced.

Corresponding to the above method embodiment, the embodiment of the present invention further provides a communication interlock device, and the communication interlock device described below and the communication module switching method described above may be referred to in correspondence with each other.

In the device, whether the Beidou regional short message module is in a radio frequency spectrum control region or not is determined by acquiring the position of the local machine and based on the position of the local machine. If the judgment result is yes, the Beidou regional short message module cannot be used at the moment, and the iridium satellite receiving and transmitting module and the Beidou global short message module can be shared in consideration of the fact that the iridium satellite receiving and transmitting module does not have an interference problem, so that at least one module of the iridium satellite receiving and transmitting module and the Beidou global short message module can be used for communication at the moment. If the judgment result is no, the Beidou regional short message module can be considered to be used at the moment, but the interference problem exists between the Beidou regional short message module and the iridium satellite receiving and sending module, so that the Beidou regional short message module can be used for communication under the condition that the iridium satellite receiving and sending module and the Beidou regional short message module are not shared, namely, the iridium satellite receiving and sending module does not work, and the Beidou regional short message module has lower energy consumption relative to the Beidou global short message module, so that the Beidou regional short message module is used as much as possible, and the communication energy consumption can be reduced.
