Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, specific embodiments of the present application will be described in detail with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present application are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Fig. 1 is a flowchart of a method for automatically numbering relay responses according to an embodiment of the present disclosure, where the method for automatically numbering relay responses according to the embodiment of the present disclosure may be implemented by a relay response automatic numbering device, and the relay response automatic numbering device may be implemented in a hardware and/or software manner and integrated in a computer device.
The method for executing the automatic relay response numbering by the automatic relay response numbering device is described as an example. Referring to fig. 1, the method for automatically numbering relay responses includes:
s101: the master sends an enabling signal to the enabled end of the slave through the enabling end and broadcasts a search request carrying number information through the communication bus.
The master is sequentially connected with a plurality of slaves through a communication bus, the enabling end of the master is connected with the enabled end of the first slave, and the enabling end of the slave is connected with the enabled end of the next slave.
Fig. 2 is a schematic connection diagram of a master and a slave according to an embodiment of the present disclosure. As shown in fig. 2, the master device is provided with a master controller (CPU 0 in the figure), the master controller is provided with an enable terminal, the slave device is provided with a slave controller (CPU 1 in the figure), and the slave controller is provided with an enable terminal and an enabled terminal.
Illustratively, the serial communication interface of the master controller in the master computer is sequentially connected with a plurality of slave computers through a communication bus. Specifically, a serial communication interface of the slave controller in the slave device is connected to the communication bus. In the present embodiment, the slave (slave 0 in the figure) whose connection position is closest to the master is defined as the first slave, and the numbers of the subsequent slaves are sequentially increased (slaves 1 to N) according to the connection position from the master.
Furthermore, the enabling end of the master controller is in communication connection with the enabled end of the slave controller in the first slave machine through an enabling signal line, and the enabling end on the slave controller in each slave machine is in communication connection with the enabled end of the slave controller in the next slave machine through an enabling signal line.
When the master controller of the master machine broadcasts a message through the communication bus, the slave machines connected to the communication bus can receive the broadcast message, and each slave machine can send the message to the master controller through the communication bus. Furthermore, the search request broadcast in the communication bus is not responded to until an enable signal is received from an enabled terminal of the control module.
Specifically, when the accessed slave machines need to be numbered, the enabling end of the main controller sends an enabling signal to the enabled end of the first slave machine to activate the first slave machine, determine the slave machine number of the first slave machine, generate number information based on the slave machine number, and generate a search request carrying the number information. Further, after the search request is generated, the search request is broadcast over the communication bus.
For example, the slave number of the first slave is determined to be 0, number information reflecting the slave number of 0 is generated, and a search request carrying the number information is generated.
S102: the slave computer responds to the enabling signal to be changed from the initial state to the number state, receives the search request through the communication bus, and determines the number of the slave computer according to number information carried by the search request.
The initial state is an operating state in which the slave does not determine the slave number or is reset, and the numbering state is an operating state in which the slave performs a numbering operation in response to an enable signal or determines the slave number.
For example, the slave controller of the slave machine receives the enable signal and then converts the initial state of the slave machine into the numbering state in response to the enable signal, so that the slave machine performs the numbering operation in the numbering state.
Further, after the slave machine is changed from the initial state to the number state, the slave machine receives the search request broadcasted in the communication bus from the controller, and analyzes the search request to obtain the number information carried by the search request. And after the number information is obtained, determining the slave machine number of the slave machine according to the number information.
For example, when the number information indicating that the slave number is 0 is obtained by interpreting the search request, the slave number is determined to be "0".
S103: the slave machine returns the number response information to the master machine, and sends an enabling signal to the enabled end of the next slave machine through the enabling end after the number information carried by the search request is updated so as to inform the next slave machine of carrying out the number operation.
For example, after determining the slave number of the slave, the slave generates a number response message and returns the number response message to the master through the communication bus. Meanwhile, after the number information carried by the search request is updated, an enabling end sends an enabling signal to an enabled end of the next slave machine through the enabling end so as to inform the next slave machine of carrying out the number operation. The update of the number information may be determined by notification from the master controller or monitoring of the number information from the slave.
In one embodiment, the determining the update of the number information through the notification of the main controller specifically includes: the slave machine returns the number response information to the master machine, and after receiving the number updating notice sent by the master machine, the slave machine sends an enabling signal to the enabled end of the next slave machine through the enabling end so as to inform the next slave machine of carrying out the number operation.
Specifically, the master generates a number update notification after receiving the number response information and updating the number information, and transmits the number update notification to the slave that has transmitted the number response information. And after receiving the number updating notification, the slave machine determines that the number information carried by the search request is updated, and sends an enabling signal to an enabled end of the next slave machine through the enabling end so as to notify the next slave machine of carrying out the number operation.
In one embodiment, the determining of the update of the number information through the monitoring of the slave machine includes: the slave machine returns the number response information to the host machine, compares the number of the slave machine with the number information carried by the search request and generates a comparison result; and the slave sends an enabling signal to an enabled end of the next slave through the enabling end based on the comparison result that the indication number information is inconsistent with the slave number so as to inform the next slave of carrying out the numbering operation.
Specifically, after the slave machine returns the number response information to the master machine, the slave machine analyzes and acquires the number information carried in the search request in real time, compares the real-time number information with the number of the slave machine, if the real-time number information is consistent with the number of the slave machine, the master machine is considered not to finish updating the number information, if the real-time number information is not consistent with the number of the slave machine, the master machine is considered to finish updating the number information, the next slave machine can be informed to execute the number operation, and the enable end sends an enable signal to the enabled end of the next slave machine to inform the next slave machine to perform the number operation.
It can be understood that after the enabled end of the next slave receives the enable signal, the processing mode of the next slave is consistent with the processing mode of the slave sending the enable signal, that is, in response to the enable signal being changed from the initial state to the numbering state, the next slave receives the search request through the communication bus, determines the slave number according to the number information carried by the search request, returns the number response information to the master, and sends the enable signal to the enabled end of the next slave through the enable end after the number information carried by the search request is updated so as to inform the next slave to perform the numbering operation.
S104: and the host updates the number information carried by the search request in response to the number response information and broadcasts the updated search request through the communication bus.
For example, after receiving the number response information returned by the slave, the master determines that the corresponding slave has completed the number, and updates the number information carried in the search request in response to the number response information. The number information may be updated according to a preset updating manner, for example, a current number is incremented.
Further, after the updating of the number information is completed, the number information is replaced and updated for the number information originally carried in the search request, so that the search request is updated, and the updated search request is broadcast through the communication bus.
The slave that has newly received the enable signal may perform a numbering operation in response to a search request broadcast in the communication bus.
Assuming that after the first slave machine finishes the numbering operation, the master machine responds to the numbering response information to update '0' in the numbering information carried by the search request to '1', after the second slave machine receives the enabling signal from the first slave machine, the second slave machine receives the search request from the communication bus and determines that the numbering information is '1', the number of the slave machine is determined to be '1', the numbering response information is returned to the master machine, the enabling signal is sent to the third slave machine, and the operation is repeated in sequence in a circulating mode, so that the slave machines perform relay response on the search request, and the automatic numbering of all the slave machines connected in sequence is realized.
By connecting the slaves in turn to the master, the master can respond to the search request broadcast by the master by sending an enable signal to the first slave, and determines the self slave machine number according to the number information carried by the search request, and returns the number response information to the host machine, the host machine updates the number information after receiving the number response information, meanwhile, the slave machine which determines the number of the slave machine sends an enabling signal to the next slave machine, so that the next slave machine responds to the search request and carries out numbering operation according to the updated number information, thereby leading the slave machines to finish automatic numbering in a relay response mode, effectively improving the numbering efficiency of the slave machines, and the numbers of the slave machines are numbered according to the connection sequence of the slave machines connected with the master machine, and the numbers do not need to be numbered again or manually according to the installation sequence of the slave machines, so that the flexibility of the numbers of the slave machines is improved.
Fig. 3 is a flowchart of another method for automatically numbering relay responses according to an embodiment of the present disclosure, where the method for automatically numbering relay responses is an embodiment of the method for automatically numbering relay responses. Referring to fig. 3, the method for automatically numbering relay responses includes:
s201: the master sends an enabling signal to the enabled end of the slave through the enabling end and broadcasts a search request carrying number information through the communication bus.
S202: the slave computer responds to the enabling signal to be changed from the initial state to the number state, receives the search request through the communication bus, and determines the number of the slave computer according to number information carried by the search request.
S203: the slave machine returns the number response information to the master machine, and sends an enabling signal to the enabled end of the next slave machine through the enabling end after the number information carried by the search request is updated so as to inform the next slave machine of carrying out the number operation.
S204: and the host computer responds to the number response information to perform number increasing processing on the number information, updates the number information subjected to the number increasing processing into the search request, and broadcasts the updated search request through the communication bus.
Specifically, after receiving the number response information returned by the slave, the master determines that the corresponding slave has completed the number, and performs number increasing processing on the number information carried by the current search request. For example, if the number information carried by the current search request is "2" and the number response information returned by the third slave is received at this time, it is considered that the third slave has completed the number operation, and the number information needs to be updated for the fourth slave to perform the number operation, the number information is incremented, and the number information is updated to "3".
Further, after the updating of the number information is completed, the number information is replaced and updated for the number information originally carried in the search request, so that the search request is updated, and the updated search request is broadcast through the communication bus.
The slave which receives the enabling signal newly can respond to the searching request broadcasted in the communication bus and obtain the updated number information in the searching request for numbering operation.
S205: the host determines the broadcast time length of the current search request and stops the broadcast of the search request when the broadcast time length reaches a preset timeout time length.
Specifically, after the host finishes updating the number information and broadcasts the search request through the communication bus, counting the broadcast time length of the current search request, comparing the broadcast time length with the preset timeout time length, and when the broadcast time length reaches the preset timeout time length, considering that no new slave machines receive the enable signal and respond to the search request, at this time, the numbers of all the slave machines are finished, and the broadcast of the search request is stopped.
It can be understood that the broadcast time length is used for counting the time length of the search request broadcast in the communication bus corresponding to each different number information, the host stops the timing of the broadcast time length and resets the broadcast time length when receiving the number response information, and the timing of the broadcast time length is started after the updated search request is rebroadcast.
Fig. 4 is a timing diagram of a method for automatically numbering relay responses according to an embodiment of the present application, and as shown in fig. 4, when slaves (modules 0 to N in the figure) accessing a master need to be numbered, the master first sends an enable signal to a first slave (module 0) through an enable terminal, and broadcasts a search request carrying number information "0" through a communication bus.
And the first slave machine converts the initial state into the number state after receiving the enabling signal, analyzes and obtains the number information in the search request corresponding to the search request in the number state, and determines the number of the slave machine per se to be 0 according to the number information. After the confirmation of the slave number is completed, the number response message is returned to the master and an enable signal is sent to the second slave (module 1).
After receiving the number response information returned by the first host, the host updates the number information carried by the search request, namely, the number information of "0" is updated to "1", and broadcasts the search request carrying the updated number information through the communication bus.
And after receiving the enabling signal, the second slave machine receives the search request broadcasted in the communication bus and performs numbering operation, and sequentially relays the search request to the following slave machines to perform numbering operation until the broadcast time length of the search request reaches a preset timeout time length, so that numbering of all the slave machines is completed.
By connecting the slaves in turn to the master, the master can respond to the search request broadcast by the master by sending an enable signal to the first slave, and determines the self slave machine number according to the number information carried by the search request, and returns the number response information to the host machine, the host machine updates the number information after receiving the number response information, meanwhile, the slave machine which determines the number of the slave machine sends an enabling signal to the next slave machine, so that the next slave machine responds to the search request and carries out numbering operation according to the updated number information, thereby leading the slave machines to finish automatic numbering in a relay response mode, effectively improving the numbering efficiency of the slave machines, and the numbers of the slave machines are numbered according to the connection sequence of the slave machines connected with the master machine, and the numbers do not need to be numbered again or manually according to the installation sequence of the slave machines, so that the flexibility of the numbers of the slave machines is improved. Meanwhile, counting the broadcast time length of the search request, and stopping the broadcast of the search request when the broadcast time length reaches the preset timeout time length to finish the numbering operation of all the slave machines.
Fig. 5 is a flowchart of another method for automatically numbering relay responses according to an embodiment of the present disclosure, where the method for automatically numbering relay responses is an embodiment of the method for automatically numbering relay responses. Referring to fig. 5, the method for automatically numbering relay responses includes:
s301: the master sends an enabling signal to the enabled end of the slave through the enabling end and broadcasts a search request carrying number information through the communication bus.
S302: the slave machine acquires the self number determining state and performs reset operation when the number determining state is an undetermined number, so that the slave machine is set to be in an initial state.
Specifically, when the slave accesses the communication bus, the slave checks its own number determination state, and if the own number determination state is an undetermined number and the operating state of the slave is not in the initial state, a reset operation is performed to set the slave to the initial state. The number determination state is changed to a state of determination number when the slave determines its own slave number.
S303: the slave computer responds to the enabling signal to be changed from the initial state to the number state, receives the search request through the communication bus, and determines the number of the slave computer according to number information carried by the search request.
S304: the slave machine returns the number response information to the master machine, and sends an enabling signal to the enabled end of the next slave machine through the enabling end after the number information carried by the search request is updated so as to inform the next slave machine of carrying out the number operation.
S305: and the host updates the number information carried by the search request in response to the number response information and broadcasts the updated search request through the communication bus.
S306: and the host machine compares the updated number information with the slave machine number of the accessed slave machine, and determines the coincidence information according to the comparison result.
Specifically, after the number information is updated, the master compares the updated number information with the slave numbers of the accessed slaves, so as to determine whether the slave numbers determined previously coincide with the current number information, and generates coincidence information according to the comparison result. After receiving the serial number response information, the master records the serial number of the slave corresponding to the serial number response information as the serial number of the slave which is accessed.
S307: and when the superposition information indicates that the updated serial number information is superposed with the serial number of the accessed slave, the master generates update failure information.
Specifically, when the registration information indicates that the updated number information coincides with the slave number of the accessed slave, the master changes the registration information to generate the update failure information, considering that the currently updated number information is used for the situation that the numbers coincide after the numbering operation.
And if the superposition information indicates that the updated number information is inconsistent with the slave machine number of the accessed slave machine, the currently updated number information is considered to be available for numbering operation, and the number information does not need to be updated again.
S308: the host renews the number information in response to the update failure information.
Specifically, after the update failure information is generated, the host renews the number information, that is, performs an operation of adding one on the basis of the current number information. It is understood that after the number information is updated again, the currently updated number information is compared with the slave numbers of the accessed slaves again until the number information is inconsistent with the slave numbers of the accessed slaves.
For example, the updated number information is "2", which corresponds to the third slave, but the third slave has already completed the number operation, and at this time, the updated number information coincides with the slave number of the accessed slave, the master generates the update failure information, and re-updates the number information in response to the update failure information, that is, performs an adding operation on the basis of the number information being "2", re-updates the number information to "3", and re-compares the currently updated number information with the slave number of the accessed slave until the number information does not coincide with the slave number of the accessed slave.
By connecting the slaves in turn to the master, the master can respond to the search request broadcast by the master by sending an enable signal to the first slave, and determines the self slave machine number according to the number information carried by the search request, and returns the number response information to the host machine, the host machine updates the number information after receiving the number response information, meanwhile, the slave machine which determines the number of the slave machine sends an enabling signal to the next slave machine, so that the next slave machine responds to the search request and carries out numbering operation according to the updated number information, thereby leading the slave machines to finish automatic numbering in a relay response mode, effectively improving the numbering efficiency of the slave machines, and the numbers of the slave machines are numbered according to the connection sequence of the slave machines connected with the master machine, and the numbers do not need to be numbered again or manually according to the installation sequence of the slave machines, so that the flexibility of the numbers of the slave machines is improved. Meanwhile, the updated number information is compared with the slave machine number of the accessed slave machine, so that the situation that the updated number information is repeated with the slave machine number of the accessed slave machine is reduced, and the accuracy of the slave machine number is ensured.
