Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present 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.

In the field of communication, most of chips used in a conventional communication flow do not have a communication function like an I2C bus, that is, a communication address of a module to be communicated can be known, but a communication address of a communication module is unknown, so that communication cannot be normally performed, for example, in the case that only one 485 interface is provided but two identical modules need to be connected, if the communication addresses of the two modules are unknown, that is, the two modules cannot be distinguished by addresses, the two communicating modules can be distinguished by means of related technical means, so that communication can be normally performed.

The invention provides a module communication method, which is applied to a slave communication module, and aims to distinguish a plurality of slave communication modules to be communicated with a master communication module under the condition of relatively deficient hardware resources, so that only two communication modules are communicated with the same bus at the same time, and the stable communication work is ensured, wherein FIG. 1 is one of the flow schematic diagrams of the module communication method provided by the invention, and as shown in FIG. 1, the method comprises the following steps:

step 110, receiving a communication instruction sent by a main communication module;

specifically, in the case where the master communication module does not establish a communication connection with any slave communication module, if communication with a slave communication module is required, a communication instruction may be sent through the communication interface to communicate with the slave communication module that has received and responded to the communication instruction.

The slave communication module may receive the communication instruction sent by the master communication module, and may respond to the received communication instruction, that is, generate a communication reply instruction corresponding to the communication instruction, and return the communication reply instruction to the master communication module that sent the communication instruction, where the communication reply instruction is intended to indicate that the slave communication module responds to a communication request sent by the master communication module, that is, the communication request of the master communication module should be allowed.

It should be noted that the master communication module only sends the communication command to the communication interface when the master communication module does not establish a communication connection with any slave communication module, that is, when the master communication module does not normally communicate with any slave communication module, and once the master communication module establishes a communication connection with any slave communication module, that is, when the master communication module enters a normal communication flow with the slave communication module, the master communication module stops sending the communication command until the communication connection is disconnected.

Step 120, generating a communication reply instruction based on the communication instruction, and sending the communication reply instruction to the master communication module to request the master communication module to generate and send a communication confirmation instruction after receiving the communication reply instruction;

specifically, in step 110, in the case that a communication instruction sent by the master communication module has been received, step 120 may be executed, that is, a communication reply instruction is generated according to the communication instruction and sent to the master communication module, so that the master communication module can generate and send a communication confirmation instruction after receiving the communication reply instruction, and this process specifically includes the following steps:

under the condition of receiving a communication instruction sent by the master communication module, firstly, the slave communication module can respond to the communication instruction, namely, a communication reply instruction corresponding to the communication instruction can be generated by taking the communication instruction as a reference, and the communication reply instruction is intended to indicate that the slave communication module responds to a communication request sent by the master communication module, namely, the communication request of the master communication module is allowed;

subsequently, the slave communication module returns the generated communication reply instruction corresponding to the communication instruction to the master communication module which sends the communication instruction, that is, the communication reply instruction is sent to the master communication module, and the master communication module can receive the communication reply instruction returned by the slave communication module based on the communication instruction and generate a communication confirmation instruction after receiving the communication reply instruction, wherein the communication confirmation instruction is intended to confirm whether to respond to the communication request with the slave communication module which returns the communication reply instruction;

after that, the master communication module can send the communication confirmation instruction to the slave communication module returning the communication reply instruction to request that the slave communication module can respond to the communication confirmation instruction after receiving the communication confirmation instruction, and accordingly respond to the establishment of the communication connection between the two modules.

Step 130, receiving a communication confirmation instruction sent by the master communication module, and replying to a communication confirmation reply instruction generated by the master communication module based on the communication confirmation instruction to request the master communication module to establish communication connection with the slave communication module after receiving the communication confirmation reply instruction.

Specifically, in step 120, the master communication module generates and sends a communication confirmation instruction when receiving a communication reply instruction returned by the slave communication module based on the communication instruction, at this time, step 130 may be executed, that is, the slave communication module may receive the communication confirmation instruction sent by the master communication module and may reply the communication confirmation reply instruction generated by the master communication module based on the communication confirmation instruction, so that the master communication module establishes a communication connection with the slave communication module after receiving the communication confirmation reply instruction, and the specific process includes the following steps:

firstly, the slave communication module may receive a communication confirmation instruction sent by the master communication module, and may respond to the communication confirmation instruction, that is, confirm that the communication request of the master communication module should be granted, and the specific process may be, with the communication confirmation instruction as a reference, generating a communication confirmation reply instruction corresponding thereto, and returning the communication confirmation reply instruction to the master communication module that sent the communication confirmation instruction;

then, the master communication module receives a communication confirmation reply instruction returned by the slave communication module based on the communication confirmation instruction, namely the master communication module receives a confirmation compliant reply of the slave communication module to the communication request sent by the master communication module, and then the communication confirmation reply instruction can be used for establishing communication connection between the master communication module and the slave communication module, so that the master communication module and the slave communication module can normally communicate.

In addition, it should be noted that after the communication between the master communication module and the slave communication module is completed, the communication connection can be directly disconnected, and the communication is switched to the next slave communication module which needs to communicate with the master communication module, and then the above processes are repeated, so that only two communication modules on the same bus communicate at the same time, and the communication between the master communication module and a plurality of slave communication modules can be ensured to be stably performed.

The module communication method provided by the invention comprises the steps of receiving a communication instruction sent by a main communication module, generating a communication reply instruction according to the communication instruction, sending the communication reply instruction to the main communication module, and requesting the main communication module to generate and send a communication confirmation instruction after receiving the communication reply instruction; the communication confirmation method comprises the steps of receiving a communication confirmation instruction sent by a main communication module, replying a communication confirmation reply instruction generated by the main communication module based on the communication confirmation instruction, requesting the main communication module to establish communication connection with a slave communication module after receiving the communication confirmation reply instruction, overcoming the defect that communication cannot be normally carried out due to the fact that a communication address of the communication module is unknown in the traditional scheme, distinguishing communication sequences between a plurality of slave communication modules and the main communication module under the condition that hardware resources are urgent, ensuring stable operation of communication on a bus, and simultaneously improving communication efficiency to a great extent by a non-interrupted communication mode.

Based on the above embodiment, the method further comprises:

receiving a communication ending instruction sent by a main communication module;

under the condition that the communication connection is disconnected in advance, if a communication ending instruction sent again by the main communication module is not received within first preset time, the communication connection is determined to be disconnected;

Specifically, when the communication is completed, the master communication module may further send a communication end instruction to the slave communication module that establishes the communication connection through the communication interface, which is intended to end the communication with the slave communication module, and the slave communication module may receive the communication end instruction sent by the master communication module, and may respond to the received communication end instruction, that is, may generate a communication end reply instruction corresponding to the communication end instruction sent by the master communication module, which indicates that the communication end request of the master communication module should be granted;

then, the slave communication module needs to return a communication end reply instruction to the master communication module which sends the communication end instruction, and at the same time, the slave communication module starts a timeout management mechanism, namely, starts a pre-disconnection mode, in other words, the slave communication module can control the communication connection between the master communication module and the slave communication module to be pre-disconnected under the condition that the communication end reply instruction is sent to the master communication module;

correspondingly, the main communication module can send the communication ending instruction again after receiving the communication ending reply instruction of the communication ending instruction sent by the slave communication module;

further, under the condition that the communication connection between the master communication module and the slave communication module is disconnected in advance, if the slave communication module fails to receive a communication ending instruction sent again by the master communication module within a first preset time, the communication connection between the master communication module and the slave communication module is determined to be disconnected; correspondingly, under the condition that the communication connection between the master communication module and the slave communication module is disconnected in advance, if the slave communication module receives a communication ending instruction sent again by the master communication module within the first preset time, it is determined that the communication connection between the master communication module and the slave communication module is not disconnected temporarily, at this time, a communication ending reply instruction can be generated according to the received communication ending instruction and sent to the master communication module, the above process is repeated until the slave communication module fails to receive the communication ending instruction sent latest by the master communication module within the first preset time, and at this time, it is determined that the communication connection between the slave communication module and the master communication module is disconnected.

It should be noted that the first preset time here may be set according to actual requirements, and it needs to be smaller than a time interval from sending the communication end instruction to sending the communication end instruction again by the main communication module, and in an embodiment of the present invention, the first preset time is determined to be 1 second.

In addition, in the case that the communication connection between the master communication module and the slave communication module is disconnected, the master communication module sends a new communication instruction through the communication interface, that is, steps 110 to 130 are executed, to communicate with the next slave communication module, and when the communication is finished, the above process is repeated until there is no next slave communication module, that is, the master communication module and several slave communication modules complete the communication.

Based on the above embodiment, the method further comprises:

receiving a data interaction instruction sent by a main communication module;

the data interaction instructions include data migration instructions and/or data synchronization instructions.

Specifically, the slave communication module may receive, in addition to the communication instruction, the communication confirmation instruction, and the communication end instruction sent by the master communication module, a data interaction instruction sent by the master communication module, where the data interaction instruction may be an instruction for requesting data synchronization, that is, a data synchronization instruction, an instruction for indicating data migration, that is, a data migration instruction, and a data synchronization instruction and a data migration instruction, which is not specifically limited in this embodiment of the present invention.

Further, under the condition that the communication connection is established between the master communication module and the slave communication module, the slave communication module can respond to the received data interaction instruction, that is, can perform data interaction with the master communication module according to the data interaction instruction, and specifically, can perform data synchronization with the master communication module according to a data synchronization instruction in the data interaction instruction; or carrying out data migration with the main communication module according to a data migration instruction in the data interaction instruction; or the data interaction module and the main communication module respectively carry out data synchronization and data migration according to a data synchronization instruction and a data migration instruction in the data interaction instruction.

Correspondingly, under the condition that the communication connection between the master communication module and the slave communication module is not established, the slave communication module does not respond to the received data interaction instruction sent by the master communication module, namely does not respond to the data interaction request of the master communication module until the master communication module and the slave communication module establish communication connection, so that only two communication modules can be ensured to communicate on the same bus at the same time, and key benefits are provided for the stable communication operation.

Based on the above embodiments, the general flow of the module communication method can be divided into the following processes, fig. 2 is one of the general flow charts of the module communication method provided by the present invention, as shown in fig. 2, the method includes the following steps:

then, a communication confirmation instruction sent by the master communication module may be received, and in a case that the communication confirmation instruction is received, a communication confirmation reply instruction generated by the master communication module based on the communication confirmation instruction is replied to request the master communication module to establish communication connection with the slave communication module after receiving the communication confirmation reply instruction.

Correspondingly, when the communication is finished, the slave communication module can receive a communication ending instruction sent by the master communication module, generate a communication ending reply instruction according to the communication ending instruction under the condition that the communication ending instruction is received, send the communication ending reply instruction to the master communication module, and meanwhile, the slave communication module controls the communication connection to be disconnected in advance;

further, under the condition that the communication connection is disconnected in advance, if a communication ending instruction sent again by the main communication module is not received within a first preset time, the communication connection is determined to be disconnected;

Step 320, in the case of receiving the communication reply instruction returned from the communication module, generating a communication confirmation instruction, and sending the communication confirmation instruction to the slave communication module to request the slave communication module to generate a communication confirmation reply instruction based on the communication confirmation instruction after receiving the communication confirmation instruction, and returning the communication confirmation reply instruction;

specifically, in step 310, on the basis that the slave communication module returns the communication reply instruction generated according to the communication instruction to the master communication module, step 320 may be executed, and in the case that the communication reply instruction returned from the slave communication module is received, a communication confirmation instruction is generated and sent to the slave communication module, so that the slave communication module generates the communication confirmation reply instruction according to the communication confirmation instruction and returns the communication confirmation reply instruction, and the specific process includes the following steps:

first, the master communication module may receive a communication reply instruction returned by the slave communication module based on the communication instruction, and in a case where the communication reply instruction is received, generate a communication confirmation instruction intended to confirm with the slave communication module whether or not to respond to the communication request issued by the master communication module, and transmit the communication confirmation instruction to the slave communication module;

the slave communication module may receive the communication confirmation instruction sent by the master communication module, and may respond to the communication confirmation instruction to confirm that the communication request of the master communication module is allowed, where a specific process may be to generate a communication confirmation reply instruction corresponding to the communication confirmation instruction based on the communication confirmation instruction, and return the communication confirmation reply instruction to the master communication module that sent the communication confirmation instruction.

And step 330, receiving a communication confirmation reply instruction returned by the slave communication module, and establishing communication connection with the slave communication module based on the communication confirmation reply instruction.

Specifically, in step 320, in the case that the slave communication module has returned the communication confirmation reply instruction generated according to the communication confirmation instruction to the master communication module, step 330 may be executed to receive the communication confirmation reply instruction returned from the slave communication module, and establish a communication connection with the slave communication module according to the communication confirmation reply instruction, where the master communication module receives the communication confirmation reply instruction returned by the slave communication module based on the communication confirmation instruction, and in the case that the communication confirmation reply instruction is received, that is, in the case that the master communication module receives a confirmation response that the slave communication module is allowed to send a communication request to the master communication module, establish a communication connection with the slave communication module according to the communication confirmation reply instruction, so as to ensure that the communication between the master communication module and the slave communication module can be performed normally.

The module communication method provided by the invention comprises the steps of sending a communication instruction to request a slave communication module to generate a communication reply instruction according to the communication instruction after receiving the communication instruction, and returning the communication reply instruction; under the condition of receiving a communication reply instruction returned from the communication module, generating a communication confirmation instruction, and sending the communication confirmation instruction to the slave communication module so as to request the slave communication module to generate a communication confirmation reply instruction according to the communication confirmation instruction after receiving the communication confirmation instruction, and returning the communication confirmation reply instruction; the communication confirmation reply instruction returned by the slave communication module is received, and the communication connection with the slave communication module is established according to the communication confirmation reply instruction, so that the defect that the communication cannot be normally carried out due to the fact that the communication address of the communication module is unknown in the traditional scheme is overcome, the communication sequence between a plurality of slave communication modules and the master communication module can be distinguished under the condition that hardware resources are urgent, the stable operation of communication on a bus is guaranteed, and meanwhile, the communication efficiency is improved to the greatest extent by a non-interrupted communication mode.

Based on the above embodiment, the method further comprises:

and under the condition that a communication ending reply instruction returned from the communication module is received, the communication ending instruction is sent again, and if the communication ending reply instruction returned from the communication module based on the communication ending instruction sent again is not received within a second preset time, the communication connection is determined to be disconnected.

then, the slave communication module needs to return a communication end reply instruction to the master communication module which sends the communication end instruction, and at the same time, the slave communication module starts a timeout management mechanism, namely, starts a pre-disconnection mode, which can also be understood as that the slave communication module can control the communication connection between the master communication module and the slave communication module to be pre-disconnected under the condition that the communication end reply instruction is sent to the master communication module;

subsequently, the master communication module may receive a communication end reply instruction returned by the slave communication module based on the communication end instruction, and after receiving the communication end reply instruction, send the communication end instruction again;

further, in the case that the communication connection between the master communication module and the slave communication module is pre-disconnected, if the master communication module fails to receive a communication end reply instruction returned by the slave communication module based on the re-sent communication end instruction within the second preset time, in other words, if the slave communication module fails to receive the communication end instruction sent again by the master communication module within the first preset time, it is determined that the communication connection between the master communication module and the slave communication module is disconnected.

Accordingly, in the case that the communication connection between the master communication module and the slave communication module is pre-disconnected, if the master communication module receives a communication end reply instruction returned by the slave communication module based on the re-sent communication end instruction within a second preset time, in other words, if the slave communication module receives the communication end instruction re-sent by the master communication module within a first preset time, it is determined that the communication connection between the master communication module and the slave communication module is not disconnected temporarily, at this time, the slave communication module may generate a communication end reply instruction according to the received communication end instruction and send it to the master communication module, and repeat the above process until the master communication module fails to receive the communication end reply instruction returned by the slave communication module based on the re-sent communication end instruction within the second preset time or the slave communication module fails to receive the communication end instruction sent by the master communication module within the first preset time, at which point it can be determined that the communication connection between the two is broken.

thereafter, the master communication module may receive a communication confirmation reply instruction returned from the slave communication module, and establish a communication connection with the slave communication module in a case where the communication confirmation reply instruction is received.

Correspondingly, when the communication is finished, the master communication module sends a communication ending instruction to the slave communication module to request the slave communication module to generate a communication ending reply instruction based on the communication ending instruction after receiving the communication ending instruction, and returns the communication ending reply instruction, and meanwhile, the communication connection is controlled to be disconnected in advance;

the master communication module can receive a communication ending reply instruction returned by the slave communication module based on the communication ending instruction, and after receiving the communication ending reply instruction, the master communication module sends the communication ending instruction again;
