The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

In the embodiment of the present invention, the outdoor unit has two working modes, one is a main program area working mode, and the outdoor unit has a command to respond to the indoor unit when operating in the mode, and can adjust power in real time, detect alarms, and report in real time. The electric equal function; the other is the boot program area working mode, in which the functions of the outdoor unit are relatively simple, mainly including the boot function, the download version function, and the maintenance power adjustment function. The working mode of the boot program area is a transition mode in which the outdoor unit enters the working mode of the main program area, or performs corresponding service maintenance and software version update, and the switching between the two modes is realized by the jump instruction. The jump instruction is implemented by modifying the processor's program counter register (PC register, Program Counter Register). When the device needs to jump, the address of the corresponding target program command is transmitted to the program count register of the central processing unit (CPU), and the device can start execution from the corresponding address of the target program.

Each startup of the device includes a restart, and the outdoor unit first enters the boot program area working mode, and then determines to determine the startup type of the outdoor unit to determine whether it needs to continue to work in the boot program area, when it needs to be maintained in the boot program area. When working, the software content is updated in this mode, the update is restarted again, and finally the main program area runs normally. The outdoor unit initializes the peripheral unit before the outdoor unit cuts into the main program area from the boot program area. If the type of the current startup is normal startup, the outdoor unit initializes all the peripherals. Reconfigure the peripheral's I/O port 10-port properties, reconfigure the peripheral registers, set all attenuators to maximum attenuation, and all frequencies are initialized to 0; if the current startup type is a reboot caused by a version update , the outdoor unit performs a soft restart.

In the software version update method provided by the embodiment of the present invention, after receiving the version update request information in the normal operation process, the outdoor unit cuts into the boot program area work, maintains the basic service content while maintaining the basic service, and the content update is completed, the outdoor unit Perform a soft restart. Because the critical control information remains in the memory reservation area during the update process and in the restart caused by the update, the outdoor unit can maintain the ongoing service without any interruption of the service.

The specific implementation steps are as shown in FIG. 1, and include:

Step 101: Receive a software version update request message.

Step 102, cutting into the boot program area, performing service maintenance in the boot program area, and performing software content update;

Preferably, the method further includes: performing a soft restart.

The embodiment of the invention further provides a computer storage medium, wherein the computer storage medium stores a first set of computer executable instructions, and the computer executable instructions are used to execute the foregoing software version update method. The first embodiment is as shown in FIG. 2, and the method for performing software version update on the outdoor unit includes: Step 201: The outdoor unit receives a software version update request message;

During normal operation, the outdoor unit reports the status information of the version update to the indoor unit after receiving the software version update request message of the indoor unit, and the outdoor unit sets the flag bit A to indicate that the current outdoor unit is in the "version". Update status "and need to update the version, will not be able to respond to new configuration commands such as power, frequency, etc. of the indoor unit and cannot accept new services. If the user performs parameter configuration operations on the outdoor unit, the indoor unit prompts the user that the current outdoor unit is in the version update state, and requires the user to configure it later. Step 202: The outdoor unit cuts into the boot program area, performs service maintenance in the boot program area, and performs software content update.

After the outdoor unit reports the status information to the indoor unit, the working mode is switched from the main program area working mode to the boot program area by the jump. After entering the working mode of the boot program area, the outdoor unit first judges the type of startup according to the flag bit A. If it is determined that the normal start, it jumps directly into the main program area, and if it is determined that the startup is required to be updated, the maintenance continues. In the boot program area working mode, the outdoor unit at this time adjusts the internal link attenuator in real time according to the current received signal size. If the received signal is found to be small, the attenuation of the receiving link is reduced. On the other hand, if the received signal is found to be too large, the attenuation of the receiving link is increased. The outdoor unit controls the attenuation of the digital-to-analog converter chip by the controller to control the attenuation. After receiving the RF signal, the outdoor unit converts the RF signal into a low frequency signal of 140 MHz (megahertz) through a series of components such as an attenuator, amplifier, and frequency converter, and sends it to the indoor unit. The 140 MHz signal sent by the outdoor unit to the indoor unit is required to have power requirements. The general rule is at the -10 dBm level. The outdoor unit has a detector at the output port. When the detected power is small, the attenuation is reduced, and vice versa. For example, if the outdoor unit detects that the current attenuation is -20dBm, then it needs to increase the attenuation by 10dB. The outdoor unit will look up the calibration data table to find the voltage at which the controller needs to output a large value at the current attenuation level. The calibration data sheet is a correspondence table of voltage and attenuation levels that is determined by the manufacturer of the outdoor unit when the equipment is shipped from the factory. If the current unit reads the current control voltage is 2V, find 2V corresponding to 5dB by looking up the calibration data table, indicating that the attenuator provides 5dB attenuation, but the attenuation needs to increase by 10dB, so the attenuation should reach 15dB. Find the calibration data table and find 15dB corresponds to 2.8V, then the digital-to-analog converter chip of the outdoor unit needs to output 2.8V to adjust the gain. At the same time, the outdoor unit updates the currently newly generated key control information into the memory reserved area, wherein the key control information is, for example, the signal frequency before the version is downloaded, the attenuator control amount before the version is downloaded, the power control value, and the like. When the outdoor unit starts to adjust the attenuation, the adjustment starting point must be the current state, not from the beginning. The start state begins, and the current state, such as the control voltage value of the attenuator, is stored in the memory reserved area during the previous business process.

The outdoor unit does not adjust the transmit link in the boot program area operating mode. The outdoor unit controls the digital-analog converter chip output voltage control attenuator through the controller. The outdoor unit also controls the filter switch through the digital input and output of the controller. The digital-to-analog conversion chip and the digital 10-port have retention characteristics. What is the control voltage or state of the attenuator before the version is downloaded, as long as the outdoor unit does not send a new signal through the controller to control the digital-to-analog conversion chip and 10 ports, after the version is downloaded The control voltage or state of the attenuator remains unchanged. In this uncontrolled manner, the outdoor unit can maintain the state of the transmitting link and maintain the transmitting link. In this mode, the outdoor unit only adjusts the reception without adjusting the transmission. Because the space transmission condition changes during the working process, the opposite end automatically adjusts its receiving adaptation because it is working normally. However, if the transmission power of the opposite end does not change, if the space transmission condition changes greatly, the local machine that is being upgraded at this time needs real-time adjustment to avoid affecting the service. The digital-to-analog conversion chip and the digital 10-port hold characteristic mean that their output voltage or state is maintained as long as they are not powered off before the controller notifies the chip to output a new voltage or state.

After the outdoor unit cuts into the working mode of the boot program area, while maintaining the above functions, the outdoor unit continuously obtains the new version of the software content information from the indoor unit through another thread, and refreshes the main program by using the online flash function of the controller. Each outdoor unit requests 250 bytes of new version data from the indoor unit. After receiving successfully, it is written online to the main program area. Repeated requests until all data has been transferred.

The new version of the content information is obtained from the indoor unit, and the main program is refreshed by using the online flash function of the controller. The outdoor unit can also write all the contents of the new version from the indoor unit and then write to the main program area.

After the software content is updated, the outdoor unit setting flag bit B indicates that it is not necessary to perform the full restart. New initialization, and clear flag A at the same time.

Step 203: The outdoor unit performs a soft restart.

After the outdoor unit completes all version content updates, it restarts once and the program starts from the first address in the program space. The outdoor unit will re-run the boot program and enter the main program after the update.

After the outdoor unit enters the boot program area working mode, it also judges whether the version needs to be updated first. If it is determined that the startup is caused by the need to update the version, the operation mode in the boot program area is maintained, and the maintenance and software version of the corresponding service are also performed. Update. If the version content is not required to be updated, the outdoor unit directly enters the main program area working mode.

When the outdoor unit switches to the working mode of the main program area, it first uses the flag bit B to judge whether the switching is caused by the updated version. If switching from the boot program working mode to the main program working mode is caused by the updated version, the outdoor unit performs special initialization: The outdoor unit reads key control information from the memory reserved area, such as the frequency before the version is downloaded, version download The previous attenuator control amount, power control value, and so on. After reading, the outdoor unit attenuator is initialized to the read value, and the frequency is initialized to the read frequency value. After the outdoor unit is cut into the new version and enters the main program area working mode, all the statuses are almost the same as before the version is downloaded, thereby avoiding the impact on the business.

During the normal operation of the outdoor unit, key control information such as the voltage control amount of each attenuator, the switch control of each filter, etc., when the information changes, the latest state is stored in the structure defined in the "memory reserved area".

Step 204: The outdoor unit sends a version update completion message to notify the indoor unit.

After the outdoor unit is working normally, the indoor unit is notified, and the version of the outdoor unit has been updated. At this time, the indoor unit releases the configuration restriction on the outdoor unit, and checks whether the power of the outdoor unit, the frequency, and the like are consistent with those before the restart. If the information is not consistent, the related information is reconfigured.

The steps shown in Figure 2 can be performed in accordance with the flow shown in Figure 3. Since the steps of the embodiment of the present invention need to use the independent memory reserved area to save the key control information, so as to implement the version update that does not affect the service, the division of the memory reserved area is as follows: Before compiling the program, in the memory configuration file Plan processor memory, allocate "heap space" and "memory reserved area" for the program. Arrange non-overlapping address spaces for "heap space" and "memory reserved area" to prevent program running data from affecting "memory reserved area". The memory reserved area is used to store and read key control information when switching versions.

The detailed process of storing and reading key control information is as follows:

The structure is defined and specified by code. The structure is stored in the memory reserved area. The structure is defined as follows. The members covered here are the key control information mentioned above.
