As introduced in the background art, the platform to which the metering automation terminal is applicable is constantly optimized and updated to meet the increasing demands of users, but the old metering automation terminal cannot adapt to the new platform, and operation errors often occur.
The problem can be solved by the following two methods, namely, firstly, an identification pin is added on the metering automation terminal, and a platform is identified by the identification pin, but the method only aims at a new metering automation terminal, and an old metering automation terminal cannot adapt to the new platform.
And secondly, storing the platform information of different platforms in a memory included in the metering automation terminal, and identifying the platform by comparing the platform information. However, this method requires additional steps during production in the workshops, which increases production costs, and the metering automation terminal runs the wrong program when the platform information is lost.

In view of this, the embodiment of the application provides a platform identification method, which adjusts a level mode output by at least one identification module through a hardware structure of an existing metering automation terminal, and returns to an identification information identification platform of each identification module based on different level modes according to a platform to be identified. Thus, the recognition and application of the metering automation terminal on different platforms are realized rapidly and simply.

The memory 110, the processor 120, and other elements are electrically connected directly or indirectly to each other to achieve signal transmission or interaction.
For example, the components may be electrically connected to each other via one or more communication buses or signal lines. The platform identification means 130 comprises at least one software functional module which may be stored in the memory 110 in the form of software or firmware (firmware). The processor 120 is configured to execute executable modules stored in the memory 110, such as software functional modules or computer programs included in the platform identification device 130.

But also Digital Signal Processors (DSPs), application Specific Integrated Circuits (ASICs), field Programmable Gate Arrays (FPGAs) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components. The disclosed methods, steps, and logic blocks in the embodiments of the present application may be implemented or performed. A general purpose processor may be a microprocessor or the processor may be any conventional processor or the like.
In this embodiment, the memory 110 is configured to store a program, and the processor 120 is configured to execute the program after receiving an execution instruction. The method of flow definition disclosed in any of the embodiments of the present application may be applied to the processor 120 or implemented by the processor 120.
It will be appreciated that the structure shown in fig. 1 is merely illustrative. The metering automation terminal 100 may also have more or fewer components than shown in fig. 1 or have a different configuration than shown in fig. 1. The components shown in fig. 1 may be implemented in hardware, software, or a combination thereof.
An embodiment of the present application provides a platform identification method, which is applied to the above-mentioned metering automation terminal 100, please refer to fig. 2 in combination, and fig. 2 is one of flowcharts of the platform identification method provided in the embodiment of the present application. The specific flow shown in fig. 2 is described in detail below.
Step S1, adjusting a level pattern output by at least one identification module included in the metering automation terminal 100.
And S2, acquiring identification information of the platform to be identified returned to each identification module based on the level mode.
And step S3, identifying the attribute of the platform to be identified according to each piece of identification information, wherein the corresponding relation between the attribute of each platform and each piece of identification information is prestored in the metering automation terminal 100.
The identification module may include a plurality of identification ports, each of which is a General-purpose input/output (GPIO) port, and a level mode of the GPIO port may be configured as a pull-up mode, a pull-down mode, an open-drain mode, or a float mode.
Taking the processor included in the metering automation terminal 100 as an example, the STM32F407, when the level mode of any one GPIO port is configured as a pull-up mode, a pull-down mode or a floating mode, three kinds of check bits of uncertainty, 1, 0 and the like can be obtained in the empty-pin suspension state of the GPIO port, so that different identification information which is sent by different platforms and is composed according to different check bits can be obtained by changing the level mode of the identification port included in the identification module.
When the identification module is configured into different level modes, different platforms to be identified can return different identification information according to the level modes, and specific attributes of the platforms to be identified can be judged by identifying the identification information. In this way, the recognition and application of the metering automation terminal 100 on different platforms can be realized quickly and simply.
Further, after the attribute of the platform to be identified is identified, the corresponding application program can be operated according to the identified attribute of the platform to be identified. Thus, the problem that the metering automation terminal 100 cannot be normally used due to the fact that the metering automation terminal 100 runs application programs applicable to other platforms on the current platform is effectively avoided.
As an alternative embodiment, the metering automation terminal 100 includes an identification module, where the identification module includes a first output port, a first identification port, and a second identification port, referring to fig. 3, the level mode of the output of at least one identification module included in the metering automation terminal 100 may be adjusted through steps S111-S114.
Step S111, first, a first output port included in the identification module is adjusted to output a first preset voltage, a level mode output by the first identification port is adjusted to be a pull-down mode, and the pull-down mode is kept to be output in a first preset time.
Step S112, adjusting the level mode output by the first identification port to be a pull-up mode, and maintaining the pull-up mode for the first preset time.
Step S113, second adjusting the level mode output by the second identification port to be a pull-down mode, and maintaining the output of the pull-down mode in the first preset time.
Step S114, adjusting the level mode output by the second identification port to be a pull-up mode, and maintaining the pull-up mode for the first preset time.
Also taking the example of the processor included in the metering automation terminal 100 being STM32F407, the first output port may be a pin 5 PE6 port, the first identification port may be a pin 141 PE0 port, and the second identification port may be a pin 142 PE1 port.
It should be noted that, in different platforms, the functions of the first output port, the first identification port, and the second identification port are different, for example, the first output port may be an RE/DE port (serial port enable port), the first identification port may be an RXD port (data input pin), and the second identification port may be a TXD port (data transmit pin). For another example, the first output port, the first identification port, and the second identification port may also be empty pins, i.e., the first output port, the first identification port, and the second identification port do not function pins.
When the RE/DE port outputs a low level, check bits received by the RXD port and the TXD port can be read. Accordingly, the first preset voltage may be set to a low level.
Further, when the identification module is used, the correspondence between the attribute of each platform and each identification information may be pre-established and stored as shown in table 1.
TABLE 1
Platform 1 Platform 2
Each identification port is configured in different level modes Check bit Check bit
PE0 port is configured in a pull-down mode 1 0
PE0 Port is configured in pull-up mode 1 1
PE1 Port is configured in a pull-down mode 1 0
PE1 Port is configured in pull-up mode 1 1
Identification information 1111 0101
As can be seen from table 1, when identifying the platform to be identified, the level patterns of the first identification port (PE 0 port) and the second identification port (PE 1 port) are changed according to a preset manner, so as to obtain the identification information returned by different platforms according to different check bits. For example, the identification information returned by the platform 1 is 1111, and the identification information returned by the platform 2 is 0101. And establishing a corresponding relation between each platform attribute and the identification information as shown in the table 1, and searching the platform attribute corresponding to the identification information in the corresponding relation, thereby identifying the platform attribute of the platform to be identified.
Further, the attribute of the platform to be identified can be identified according to each piece of identification information according to the following method.
Searching whether platform attributes corresponding to the identification information are stored in the metering automation terminal 100, if yes, determining that the platform attributes are the attributes of the platform to be identified, otherwise, determining that the platform to be identified is an unknown platform.
For example, the identification information returned by the platform to be identified based on different level modes is 1111, and the corresponding relation in the lookup table 1 can be known, and the platform attribute corresponding to the identification information is platform 1. In this way, the platform to be identified can be determined as the platform 1.
As another alternative embodiment, the metering automation terminal 100 includes an identification module, where the identification module includes a second output port and a third identification port, referring to fig. 4, the level mode of adjusting the output of at least one identification module included in the metering automation terminal 100 may be implemented through steps S121-S124.
Step S121, adjusting the second output port to output a second preset voltage, adjusting the level mode output by the third identification port to be a pull-down mode, and maintaining the output of the pull-down mode for a second preset time.
Step S122, adjusting the level mode output by the third identification port to be a pull-up mode, and maintaining the pull-up mode for the second preset time.
Step 123, second adjusting the second output port to output a third preset voltage, adjusting the level mode output by the third identification port to be a pull-down mode, and maintaining the pull-down mode output within the second preset time.
Step S124, adjusting the level mode output by the third identification port to be a pull-up mode, and maintaining the pull-up mode for the second preset time.
Also taking the example of the processor included in the metering automation terminal 100 being STM32F407, the second output port may be a PA4 port with pin number 40 and the third identification port may be a PG0 port with pin number 56.
In different platforms, the functions of the second output port and the third identification port are different, for example, the second output port may be an esam_pwr_on port (a power port of an ESAM chip), and the third identification port may be an esam_cs port (a data receiving and transmitting port of the ESAM chip). For another example, the second output port, the third identification port may also be empty pins, i.e., the first output port, the first identification port, and the second identification port do not function pins.
The ESAM chip is used for encrypting various embedded terminals to realize data security storage, and the specific principle is not described here.
When the ESAM_PWR_ON port outputs a high level, the power of the ESAM chip is turned ON, and when the ESAM_PWR_ON port outputs a low level, the power of the ESAM chip is turned off. Accordingly, the second preset voltage may be set to a high level, and the third preset voltage may be set to a low level.
Further, when the identification module is used, the correspondence between the attribute of each platform and each identification information may be pre-established and stored as shown in table 2.
TABLE 2
As can be seen from table 2, when identifying the platform to be identified, the level mode of the third identification port (PG 0 port) is changed according to a preset manner, so as to obtain the identification information returned by different platforms according to different check bits. For example, the identification information returned by the platform 1 is 1100, and the identification information returned by the platform 2 is 0101. And establishing a corresponding relation between each platform attribute and the identification information as shown in the table 2, and searching the platform attribute corresponding to the identification information in the corresponding relation, thereby identifying the platform attribute of the platform to be identified.
It can be understood that the attribute of the platform to be identified can be identified according to each piece of identification information as follows.
Searching whether platform attributes corresponding to the identification information are stored in the metering automation terminal 100, if yes, determining that the platform attributes are the attributes of the platform to be identified, otherwise, determining that the platform to be identified is an unknown platform.
For example, the obtained identification information returned by the platform to be identified based on different level modes is 0101, and the corresponding relation in the lookup table 2 can be known, and the platform attribute corresponding to the identification information is platform 2. In this way, the platform to be identified can be determined as the platform 2.
As a further alternative embodiment, the platform attribute may also be identified together according to at least two different identification modules. For example, referring to fig. 5, the metering automation terminal 100 includes a plurality of identification modules, and the identification of the attribute of the platform to be identified according to each piece of identification information may be further implemented through steps S31-S34:
step S31, searching whether platform attributes corresponding to the identification information are stored in the metering automation terminal 100.
And step S32, if so, judging whether the searched platform attributes are consistent.
And step S33, if the platform attributes are consistent, determining that the platform attributes are the attributes of the platform to be identified.
Step S34, if the platform attribute corresponding to each piece of identification information is not stored in the metering automation terminal 100 or the searched platform attributes are inconsistent, determining that the platform to be identified is an unknown platform.
For example, the first output port, the first identification module and the second identification module are used for identification, the acquired identification information is 1111, and the table 1 can know that the platform attribute corresponding to the identification information is platform 1. Meanwhile, by using the second output port, the third identification module performs identification, the obtained identification information is 1100, and the lookup table 2 can know that the platform attribute corresponding to the identification information is also platform 1. Since the searched platform attributes are consistent, the attribute of the platform to be identified can be determined to be the platform 1.
For another example, the first output port, the first identification module, and the second identification module are used for identification, the acquired identification information is 1111, and the table 1 indicates that the platform attribute corresponding to the identification information is platform 1. Meanwhile, by using the second output port, the third identification module performs identification, the obtained identification information is 0101, and the lookup table 2 can know that the platform attribute corresponding to the identification information is platform 2. The platform to be identified can be determined to be an unknown platform at the moment because the searched platform attributes are inconsistent.
For another example, the first output port, the first identification module, and the second identification module are used for identification, the obtained identification information is 0101, and the table 1 indicates that the platform attribute corresponding to the identification information is platform 2. Meanwhile, by using the second output port, the third identification module performs identification, the obtained identification information is 0101, and the lookup table 2 can know that the platform attribute corresponding to the identification information is also platform 2. Since the searched platform attributes are consistent, the attribute of the platform to be identified can be determined to be the platform 2.
Therefore, the attribute of the platform to be identified is identified together according to a plurality of different identification modules, so that the identification result is more accurate.
Further, the attribute of the platform to be identified is identified according to each piece of identification information, and pre-stored information is displayed after the platform to be identified is determined to be an unknown platform so as to prompt failure in identifying the platform to be identified. So that the user can quickly acquire the state information of the current metering automation terminal 100, and the user experience is improved.
The embodiment of the application provides a platform identification method, which quickly and simply realizes the identification and application of a metering automation terminal 100 on different platforms by adjusting the level mode of at least one identification module included in the metering automation terminal and returning the identification information of each identification module to identify the platform according to the platform to be identified based on different level modes.
Referring to fig. 6 in combination, the embodiment of the present application also provides a platform identification device 130, which is applied to a metering automation terminal 100 connected to a platform to be identified, and includes:
an adjustment module 131 for adjusting a level pattern output by at least one identification module included in the metering automation terminal 100;
an obtaining module 132, configured to obtain identification information of the platform to be identified returned to each of the identifying modules based on the level mode;
and an identification module 133, configured to identify the attribute of the platform to be identified according to each piece of identification information, where the corresponding relationship between the attribute of each platform and each piece of identification information is pre-stored in the metering automation terminal 100.
It will be clear to those skilled in the art that, for convenience and brevity of description, the specific principles of the platform identification device 130 described above may refer to the corresponding procedures in the foregoing method, and will not be described in detail herein.
