Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are shown in the drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element and be integral therewith, or intervening elements may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
At present, inter-board communication is generally realized in an asynchronous or synchronous manner, so that a master control mechanism can control a slave control module, wherein the inter-board communication can be divided into four types: asynchronous duplex inter-board communication, synchronous simplex inter-board communication, and asynchronous simplex inter-board communication.
Specifically, the asynchronous duplex inter-board communication uses two independent link channels, wherein one link channel is used for transmitting, and the other link channel is used for receiving. The master control module sends a control instruction to the slave control module through the sending link of the master control module so as to realize the control of the slave control module, and receives the execution result and the feedback information returned by the slave control module through the receiving link of the master control module. And the master control mechanism adjusts the control strategy according to the received execution result and the feedback information and transmits a corresponding control instruction to the slave control module, so that closed-loop control is realized.
However, when the asynchronous duplex inter-board communication is used for communication, because two independent link channels need to be established, the cost is high, the inter-board control is asynchronous, and a certain delay exists in the control.
The synchronous duplex inter-board communication also adopts two independent link channels, wherein one link channel is used for transmitting, the other link channel is used for receiving, and meanwhile, a clock synchronization signal is also needed for carrying out communication time slot synchronization on the master control module and the slave control module. After the time slots between the boards are synchronized, the main control module receives the execution result and the feedback information returned by the slave control module through the receiving link of the main control module, and sends a control instruction to the slave control module through the sending link of the main control module according to the received execution result and the feedback information, so that closed-loop control is realized.
However, when the synchronous duplex board is used for communication, because a synchronous clock is needed and two independent link channels are established, and the communication time slots of the master control module and the slave control module are synchronously processed according to the clock synchronization signal, the implementation is complex and the cost is high.
The synchronous simplex interplate communication adopts a single communication link for communication, and needs a clock synchronization signal to carry out communication time slot synchronization on the master control module and the slave control module. After the time slots between the boards are synchronized, the master control module sends a control instruction to the slave control module through the single communication link, and the slave control module executes the control instruction according to the instruction of the control instruction. However, the slave control module cannot return the execution result and the feedback information to the master control module, so that the master control module realizes synchronous open-loop control on the slave control module when the communication is performed by the synchronous simplex inter-board communication method.
However, when communication is performed by using communication between the synchronous simplex boards, synchronous processing of communication time slots of the master control module and the slave control module by a synchronous clock is required, and only open-loop control can be realized, and the stability of control cannot be guaranteed.
The asynchronous simplex interplate communication adopts a single communication link for communication, wherein the master control module sends a control instruction to the slave control module through the single communication link, and cannot receive an execution result and feedback information returned by the slave control module, so that the master control module realizes open-loop control on the slave control module when the communication is carried out through the asynchronous simplex interplate communication method. When asynchronous simplex interplate communication is used for communication, the master control module cannot realize closed-loop control on the slave control module and cannot ensure the stability of control when an additional feedback loop is not added due to the adoption of a single communication channel.
In order to ensure the stability of control, an additional feedback loop is needed to return the execution result and feedback information of the slave control module so as to realize closed-loop control.
As shown in fig. 1, fig. 1 is a block diagram of a cycle core based on a traditional asynchronous simplex interplate communication method, and includes a master control module, a slave control module, a motion detection module, and a banknote information detection module. Specifically, the master control module transmits a control instruction to the slave control module, and the slave control module controls the motion module according to the received control instruction. The motion detection module comprising the sensor and the communication module is arranged on the motion module to detect the motion information of the motion module and transmit the motion information to the main control module through the feedback link 1, and specifically, the motion information may include the motion state and the motion position information of the motion module detected by the photoelectric position sensor and the code disc. In addition, by adding a banknote information detection module, the banknote identification state and the banknote counting information are detected and transmitted to the slave board mechanism, and the slave control module returns to the master control module through a feedback link 2 (communication link). And the master control module transmits a control adjustment instruction to the slave control module according to the received feedback information, so that closed-loop control is realized.
However, when the feedback information is returned by setting an additional feedback loop, a certain delay exists, and the real-time performance cannot be guaranteed.
In summary, if a duplex communication mode is used for inter-board communication, more hardware resources are occupied, the implementation is complex, and the cost is high; if a simplex communication mode is used for communication between boards, although the realization is simple and the cost is low, the stability cannot be ensured. The method and the device can improve the communication stability between the boards and reduce the cost.
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In one embodiment, as shown in fig. 2, there is provided a method of inter-board communication from the perspective of a slave control module, comprising the steps of:
step S202, when the master control module completes handshake and time slot synchronization in the first time slot of the communication frame and receives the control command transmitted by the master control module in the second time slot of the communication frame, the master control module transmits a motion state control signal to the motion module in the third time slot of the communication frame based on the control command.
The motion state control signal is used for indicating the motion module to adjust the working state; the first time slot, the second time slot and the third time slot may all be of different lengths.
Specifically, the slave control module and the master control module can establish communication parameters by completing handshaking in a first time slot of a communication frame and performing communication time slot synchronization by using a clock synchronization signal, and can receive a control instruction sent by the master control module in a second time slot of the communication frame. And the slave control module analyzes the control instruction in the third time slot of the communication frame, and sends a motion state control signal to the motion module based on the analysis result so as to enable the motion module to adjust the working state of the motion module and move according to the indication of the analysis result.
Furthermore, by completing tasks corresponding to the time slots in the first time slot, the second time slot and the third time slot, the communication link can be multiplexed when communication is performed through a single communication link, and the slave control module can transmit or receive information in different time slots and realize transceiving by using the single communication link.
Step S204, when the working state information of the motion module is acquired in the fourth time slot of the communication frame, the working state information is processed in the fifth time slot of the communication frame to obtain a processing result, and the processing result is transmitted to the main control module.
The fourth time slot and the fifth time slot can be different in length; and the first time slot, the second time slot, the third time slot, the fourth time slot and the fifth time slot all have different lengths.
Specifically, the slave control module sends a motion state control signal to the motion module in the third time slot of the communication frame, so that the motion module adjusts the working state of the motion module, after the motion module adjusts the motion module, the working state information of the motion module can be acquired in the fourth time slot of the communication frame, the working state information is packaged and encapsulated in the fifth time slot of the communication frame, and the processing result is transmitted to the master control module through the communication link.
Furthermore, the working state information is transmitted from the slave control module to the master control module, so that the master control module can know the working state of the motion module, and the control strategy can be adjusted in time according to the working state of the motion module. The slave control module can receive a corresponding control instruction transmitted by the master control module in the second time slot of the next communication frame, and instruct the motion module to adjust the working state through the motion state control signal so as to accord with the adjusted control strategy, thereby realizing that the working state information returns to the master control module through the slave control module, and the master control module adjusts according to the controlled output (namely the working state information) so as to realize closed-loop control.
In a specific embodiment, the method further comprises the steps of:
the communication frame is divided into a first time slot, a second time slot, a third time slot, a fourth time slot, and a fifth time slot.
Specifically, the first time slot, the second time slot, the third time slot, the fourth time slot, and the fifth time slot may have different lengths, that is, the first time slot, the second time slot, the third time slot, the fourth time slot, and the fifth time slot may be time slots with different lengths, respectively. In practical applications, the length of each timeslot can be configured according to design requirements and practical situations, so as to improve the efficiency of inter-board communication.
Further, the communication interval may be 1 millisecond, i.e., the time interval from the end of the last communication frame to the start of the current communication frame may be 1 millisecond. It should be noted that the time interval between communication frames can be configured according to design requirements and practical situations.
In the inter-board communication method, the single communication link is adopted for communication, corresponding tasks are completed in different time slots of a communication frame, control signals can be transmitted, feedback information can be received, closed-loop control can be realized without adding an additional feedback loop, and the problem that only open-loop control can be performed or closed-loop control can be realized by adding an additional feedback loop when the inter-board communication is realized based on an asynchronous simplex mode is solved, so that the stability of the inter-board communication is improved, and the real-time performance of the inter-board communication is ensured; meanwhile, the simplex communication method is used for the inter-board communication, so that the problems of high cost and the like caused by the adoption of duplex communication are solved, and the inter-board communication cost is reduced.
In one embodiment, as shown in fig. 3, there is provided a method of inter-board communication from the perspective of a slave control module, comprising the steps of:
step S302, when the master control module completes handshake and time slot synchronization in the first time slot of the communication frame and receives the control command transmitted by the master control module in the second time slot of the communication frame, the master control module transmits a motion state control signal to the motion module in the third time slot of the communication frame based on the control command.
The motion state control signal is used for indicating the motion module to adjust the working state; the first time slot, the second time slot and the third time slot can be different in length; the motion module can comprise a plurality of motion parts; the moving part may be a stepper motor.
Specifically, the slave control module and the master control module can establish communication parameters by completing handshaking in a first time slot of a communication frame and performing communication time slot synchronization by using a clock synchronization signal, and can receive a control instruction sent by the master control module in a second time slot of the communication frame. And the slave control module analyzes the control instruction in the third time slot of the communication frame, and sends a motion state control signal to the motion module based on the analysis result so as to enable the motion module to adjust the working state of the motion module and move according to the indication of the analysis result.
Step S304, in the fourth time slot, receiving the working state information transmitted by the feedback module.
In a particular embodiment, the operating status information includes the number of banknotes in the moving module, the position of each banknote, and the operating data of the moving parts.
The feedback module can comprise an infrared sensor and a photoelectric position sensor; the motion module can control the motion track of the bank note; the position of each banknote may include position information of the banknote in the motion module, and position information of the banknote in each track (i.e. channel); the operating data of the moving part may reflect the operating state of the moving part.
Specifically, the motion state of the banknote in the channel and the motion track of the banknote can be acquired through the infrared sensor, wherein the motion state of the banknote in the channel can comprise the number of banknotes in the motion module and the position of each banknote. Through the photoelectric position sensor, the working data of the stepping motor can be obtained, wherein the working data of the stepping motor can comprise the rotating speed of the stepping motor and the working state of the stepping motor. The slave control module receives the working state information transmitted by the feedback module, so that the working parameters (such as the rotating speed) of the stepping motor and whether the stepping motor is in the working state can be known.
It should be noted that the working data of the moving component is not limited to only include the rotation speed of the stepping motor (i.e., the moving component) and the working state of the stepping motor, and the parameters can be increased or decreased according to the requirement of the practical application, so that the working data can more accurately reflect the actual working condition of the moving component.
And step S306, framing is carried out based on the working state information to obtain a data frame.
The format of the data frame may be as shown in fig. 4, and includes a frame header, the number of banknotes in the motion module, the position of each banknote, information obtained by the photoelectric position sensor (i.e. the operating data of the stepping motor), and a frame end.
Specifically, the slave control module performs data packing processing on the received working state information according to a frame format shown in fig. 4, and the number of banknotes in the motion module, the position of each banknote, and information acquired by the photoelectric position sensor are included in the content of the data frame. Wherein the communication interval is 1 millisecond.
Step S308, the data frame is transmitted to the main control module.
Specifically, the data frame may be transmitted to the master control module through the communication link.
In the following, a specific example is described, as shown in fig. 5, which provides an inter-plate communication method and is described in conjunction with the running track of the bills shown in fig. 6; the inter-board communication method comprises the following steps:
step S502, the master control module sends a command indicating that the bills enter the second bill storage device to the slave control module in the first time slot of the communication frame.
Wherein, the motion module can include motion spare part and bank note storage device.
And step S504, the slave control module analyzes the control command and transmits a motion state control command to the motion module so as to control the first stepping motor, the second stepping motor and the third stepping motor in the motion module to work.
Specifically, when the first stepping motor works according to the instruction of the slave control module, the banknotes can move in the channel S101 and enter the first banknote storage device; when the second stepping motor works according to the instruction of the slave control module, the banknotes can move in the channel S102 and enter the second banknote storage device; when the third step motor works according to the instruction of the slave control module, the bank notes can move in the channel S103 and enter a third bank note storage device; the fourth stepper motor, when operated as instructed by the slave module, enables the banknote to move in the path S104 and into a fourth banknote storage device (not shown in figure 6).
In step S506, the feedback module detects the working state information of the motion module and feeds back the working state information to the slave control module.
The working state information can comprise the number of banknotes in the motion module, the position of each banknote and working data of the stepping motor; the feedback module may include an infrared sensor and an electro-optical position sensor.
Specifically, the motion state of the banknote in the channel and the motion track of the banknote can be acquired through the infrared sensor, wherein the motion state of the banknote in the channel can comprise the number of banknotes in the motion module and the position of each banknote. By detecting the position of each banknote in the motion module, it can be known whether a banknote has entered the second banknote storage device or whether it has stayed in the channel S101 or the channel S102.
Through the photoelectric position sensor, the working data of the stepping motor can be obtained, wherein the working data of the stepping motor can comprise the rotating speed of the stepping motor and the working state of the stepping motor. The slave control module receives the working state information transmitted by the feedback module, so that the working parameters (such as rotating speed) of the stepping motor and whether the stepping motor is in a working state can be known, and the number of banknotes in the motion module and the positions of the banknotes can be known at the same time.
And step S508, the slave control module packs the working state information fed back by the feedback module to obtain a data frame, and sends the data frame to the master control module every 1 millisecond.
The data frame format can be as shown in fig. 4, and includes a frame header, the number of banknotes in the motion module, the position of each banknote, information (i.e., working data of the stepping motor) obtained by the photoelectric position sensor, and a frame end; the slave control module may perform data packing according to the data frame format described in fig. 4.
Step S510, the main control module determines that the stepping motor in the motion module is in a normal motion state according to the received data frame, and performs adjustment.
Specifically, the position of each banknote is obtained from the data frame, and whether each stepping motor is in a normal working state or not is judged according to the position information of the banknote. For example, when a banknote enters the third banknote storage device, it is determined that the first stepping motor, the second stepping motor, and the third stepping motor in the motion module are in a normal operating state; when the bills stay in the passage S102, it is judged that the first stepping motor and the second stepping motor in the movement module are in a normal operating state, and the third stepping motor is not in normal movement. The master control module adjusts the control strategy and transmits the corresponding control instruction to the slave control module.
According to the inter-board communication method, the working state information transmitted by the feedback module is received, and data transmission is performed by using the data frame, so that the reliability of data is improved, and the main control module can control based on the working state information with high accuracy.
In one embodiment, as shown in fig. 7, there is provided an inter-board communication method implemented from the perspective of a master control module, including the steps of:
step 702, when the slave module completes handshake and time slot synchronization in the first time slot of the communication frame, the slave module transmits a control command to the slave module in the second time slot of the communication frame.
The control instruction is used for indicating the slave control module to transmit a motion state control signal to the motion module in a third time slot of the communication frame; the motion state control signal is used for indicating the motion module to adjust the working state.
Specifically, the master control module initiates a communication time slot synchronization and handshake request to the slave control module in a first time slot of a communication frame, and sends a control command to the slave control module in a second time slot of the communication frame after the time slot synchronization and handshake response. The control command may be determined according to the working state information acquired in the previous communication frame.
Step 704, receiving the processing result transmitted from the slave control module.
The processing result is obtained from the working state information of the motion module, which is processed by the control module in the fifth time slot of the communication frame and acquired in the fourth time slot of the communication frame.
Specifically, the main control module receives and processes the processing result to obtain the working state information of the motion module, that is, the number of the banknotes in the motion module, the positions of the banknotes, and the working data of the moving parts can be known. The master control module can obtain the motion state of the motion module according to the number of the bank notes in the motion module and the positions of the bank notes, adjust the control strategy based on the motion state of the motion module, and transmit corresponding control instructions to the slave control module. The motion state of the motion module can be used to indicate whether the moving parts in the motion module can bring each banknote to a preset position.
In the inter-board communication method, the processing result transmitted by the slave control module is received, and the master control module can adjust the control strategy according to the working state information so as to realize closed-loop control.
In one embodiment, a method of inter-board communication implemented from the perspective of a feedback module is provided, comprising the steps of:
and transmitting the working state information to the slave control module in the fourth time slot of the communication frame.
The feedback module can comprise an infrared sensor and a photoelectric position sensor; the operating state information may include the number of banknotes in the motion module, the position of each banknote, and the operating data of the stepping motor.
Specifically, the feedback module can acquire the motion state of the banknote in the channel and the motion track of the banknote through the infrared sensor, wherein the motion state of the banknote in the channel can comprise the number of banknotes in the motion module and the position of each banknote. In addition, the feedback module can obtain the working data of the stepping motor through the photoelectric position sensor. The operating data of the stepping motor may include the rotation speed of the stepping motor and the operating state of the stepping motor. And in the fourth time slot of the communication frame, the feedback module transmits the working state information to the slave control module.
In the inter-board communication method, the feedback module transmits the working state information acquired by the sensor to the slave control module, so that the output of the controlled (namely, the motion module) is returned to the slave control module, and further closed-loop control is realized.
