[0034] The method embodiment provided in this embodiment can be executed in a terminal, a computer or a similar computing device. For example, running on a terminal, Figure 1 FIG. 1 is a hardware structure diagram of a terminal of the abnormal state detection method of the state machine of this embodiment. Figure 1 As shown, the terminal may include one or more ( Figure 1 Only one is shown in the figure) processor 102 and memory 104 for storing data, wherein processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA. The above terminal may also include a transmission device 106 and an input and output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1 The structure shown is for illustration only and does not limit the structure of the above terminal. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations shown.

[0035] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the abnormal state detection method of the state machine in this embodiment. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, to implement the above method.

[0037] Exemplarily, the state machine in the present invention refers to an integrated circuit composed of a state register and a combinational logic resistor, which can transfer states according to a preset output state based on an input signal. The state machine is a control center that coordinates related signal actions in the system and completes specific operations. Among them, the state machine in the prior art is generally based on a finite state machine, that is, the output state of the state machine is limited in number. Depending on whether the output state in the finite state machine is related to the input signal, the finite state machine can be divided into a Moore-type state machine and a Millie-type state machine.

[0038] See also Figure 2 , Figure 2 FIG. 1 is a flow chart of a method for detecting an abnormal state of a state machine according to an embodiment of the present invention. In this embodiment, the method for detecting an abnormal state of a state machine includes:

[0039] S202: Acquire real-time abnormal status.

[0040] Exemplarily, if an abnormal condition occurs, the current state of the state machine is obtained as a real-time abnormal state. It is understandable that when the state machine works normally, the output state of the state machine should be the preset target state. If the output state of the current state machine is inconsistent with the target state, it indicates that an abnormal condition has occurred in the state machine, and it is necessary to obtain the real-time abnormal state of the state machine for subsequent acquisition of the input signal of the state machine through the real-time abnormal state and analysis.

[0041] S204: Acquire a corresponding first input signal sequence in a database based on the real-time abnormal state, wherein the database stores a corresponding relationship between the abnormal state and the input signal sequence, and the input signal sequence includes signal states of multiple input interfaces.

[0042] Exemplarily, the input signal sequence refers to the signal state of multiple input interfaces. Specifically, each input interface in the state machine has a corresponding state value, which is used to identify the signal state of the input interface. The state value of each input interface is arranged in a certain order to obtain the input signal sequence. The input signal sequence corresponding to each state of the state machine is pre-stored in the database. Based on this, when the output state of the state machine is an abnormal state, the corresponding first input signal sequence can be obtained in the database based on the real-time abnormal state.

[0043] S206: Compare the first input signal sequence with the second input signal sequence of the target state to obtain an abnormal signal position, where the abnormal signal position is a position where the first input signal sequence is inconsistent with the second input signal sequence.

[0044] Exemplarily, the target state preset by the current state machine is obtained, and based on the correspondence between the state machine state and the input signal sequence, the second input signal sequence corresponding to the target state is obtained in the database. The first input signal sequence is compared with the second input signal sequence bit by bit to obtain the sequence position with inconsistent values ​​as the abnormal signal position. It can be understood that the input signal corresponding to the abnormal signal position is the signal that jumps in the input signal of the real-time abnormal state.

[0045] This embodiment obtains a real-time abnormal state; based on the real-time abnormal state, a corresponding first input signal sequence is obtained in a database, and a corresponding relationship between the abnormal state and the input signal sequence is stored in the database, and the input signal sequence includes signal states of multiple input interfaces; the first input signal sequence is compared with the second input signal sequence of the target state to obtain the abnormal signal position, and the abnormal signal position is the position where the first input signal sequence is inconsistent with the second input signal sequence. Through the pre-established corresponding relationship between the state machine state and the input signal sequence, the abnormal input signal is directly obtained without the need for complex analysis through the process code or logic circuit of the state machine, which solves the technical problem of low abnormal state detection efficiency of the state machine in the prior art and improves the diagnostic efficiency of the state machine.

[0046] In another embodiment, before obtaining the real-time abnormal status, the method further includes:

[0047] Establish the corresponding relationship between the input signal sequence and the state of the state machine, and save the corresponding relationship to the database.

[0048] Exemplarily, a corresponding relationship between each input signal sequence and the state of the state machine is established, and the corresponding relationship is saved in a database. It can be understood that each input signal sequence has a unique corresponding state machine state.

[0049] Specifically, if the state machine has n input signals, and the signal state of each input signal includes "0" and "1", where "0" indicates that the input signal is not input and "1" indicates that the input signal is input, then the state machine has 2 n There are 2 combinations of input signals. n In one specific embodiment, if n=3, the state machine has eight input signal sequences including "000", "001", "010", "011", "100", "101", "110", and "111", and each input signal sequence can correspond to a state of the state machine.

[0050] In another specific embodiment, the correspondence between each input signal sequence and the state of the state machine is recorded in the form of a state table. Please refer to the following table, which is an example of a state table when the number of input signals is 3. The first row of the state table is used to record the input signal, and rows 2-9 are used to record each input signal sequence and the corresponding state machine state.

[0051] Input signal 1 Input signal 2 Input signal 3 state 0 0 0 State 1 0 0 1 State 2 0 1 0 State 3 0 1 1 State 4 1 0 0 State 5 1 0 1 State 6 1 1 0 Status 7 1 1 1 State 8

[0052] In another embodiment, the input signal includes an associated signal and a non-associated signal, and the associated signal affects the state of the state machine.

[0053] Exemplarily, the input signals of the state machine can be divided into associated signals and non-associated signals. An associated signal means that the state of the input signal will affect the output state of the state machine, and a non-associated signal means that the state of the input signal will not affect the output state of the state machine. For example, in a state machine with three input signals, a certain output state of the state machine depends only on input signal 1 and input signal 2, but has nothing to do with input signal 3, then input signal 1 and input signal 2 are associated signals, and input signal 3 is a non-associated signal.

[0054] In one specific embodiment, the correspondence between the associated signal and the non-associated signal and the state of the state machine is as shown in the following table. Among them, the input signal includes input signal 1, input signal 2 and input signal 3, input signal 1 and input signal 2 are associated signals of state 1, and input signal 3 is a non-associated signal of the state machine. At this time, under the premise that input signal 1 and input signal 2 are both in state "0", no matter whether the state of input signal 3 is "0" or "1", the output state of the state machine is state 1.

[0055] Input signal 1 Input signal 2 Input signal 3 state 0 0 X State 1 X X 0 State 2 0 1 1 State 3 1 X 1 State 4

[0056] In another embodiment, comparing the first input signal sequence with the second input signal sequence of the target state to obtain the abnormal signal position includes:

[0057] Step 1: Compare the first input signal sequence with the second input signal sequence to obtain a deviation position, where the deviation position is a position where the first input signal sequence is inconsistent with the second input signal sequence;

[0058] Step 2: Determine whether the input signal corresponding to the deviation position belongs to a related signal. If so, determine the deviation position as an abnormal signal position.

[0059] Exemplarily, the first input signal sequence corresponding to the real-time abnormal state is compared with the second input signal sequence corresponding to the target state to obtain sequence positions with inconsistent values ​​in the sequence, and the sequence positions are used as deviation positions.

[0060] Exemplarily, the category of the input signal corresponding to the deviation position is determined. If the input signal belongs to an associated signal, it indicates that the deviation position is the abnormal signal position. It is understandable that since the associated signal will affect the output state of the state machine, it is necessary to obtain the abnormal signal in the associated signal, and then correct the abnormal signal to jump out of the abnormal state of the state machine. If the input signal belongs to an unassociated signal, it indicates that the deviation position is not the abnormal signal position. It is understandable that since the unassociated signal is irrelevant to the output state of the state machine, even if the unassociated signal jumps, the output state of the state machine will not be affected. Based on this, when the input signal corresponding to the deviation position is a unassociated signal, no correction is required.

[0061] In one specific embodiment, the input signal of the state machine includes input signal 1, input signal 2 and input signal 3, wherein input signal 1 and input signal 2 are associated signals, and input signal 3 is a non-associated signal. The second input signal sequence corresponding to the target state is "010". If the first input signal sequence corresponding to the real-time abnormal state is "001", the first input sequence is compared with the second input signal sequence to obtain deviation position 1 and deviation position 2, wherein deviation position 1 is the second position in the sequence, and deviation position 2 is the third position in the sequence. The input signal 2 corresponding to deviation position 1 is an associated signal, so the input signal 2 corresponding to the abnormal state is an abnormal signal. The input signal 3 corresponding to deviation position 2 is a non-associated signal, so the input signal 3 corresponding to the abnormal state is irrelevant to the state of the state machine, that is, input signal 3 is not an abnormal signal.

[0062] In this embodiment, the first input signal sequence is compared with the second input signal sequence to obtain a deviation position, which is a position where the first input signal sequence is inconsistent with the second input signal sequence; it is determined whether the input signal corresponding to the deviation position belongs to an associated signal, and if so, the deviation position is determined as an abnormal signal position. By comparing the first input signal sequence with the second input signal sequence to obtain the deviation position, and judging whether the input signal is an abnormal signal by the relationship between the input signal corresponding to the deviation position and the associated signal, the input signal of the state machine can be flexibly set based on the associated signal and the non-associated signal. At the same time, since the non-associated signal is irrelevant to the output state of the state machine, it is not necessary to analyze the non-associated signal during detection, which reduces the cost of abnormal state detection of the state machine.

[0063] In another embodiment, after comparing the first input signal sequence with the second input signal sequence of the target state to obtain the abnormal signal position, the method further includes:

[0064] Based on the second input signal sequence, the signal state of the input interface corresponding to the abnormal signal position is adjusted.

[0065] Exemplarily, after the abnormal signal position is acquired, the signal state of the input interface corresponding to the position is adjusted to the corresponding state in the second input signal sequence, so as to realize the correction of the input signal corresponding to the real-time abnormal state.

[0066] In another embodiment, the state of the state machine includes at least a running state and a debugging state.

[0067] Exemplarily, the state of the state machine includes at least a running state and a debugging state, wherein the running state refers to the state of the state machine during normal operation, and the debugging state refers to the state of the state machine during debugging of the state machine.

[0068] Specifically, the state machine in the present invention can be applied to a mechanical device with a conveyor belt. In one of the specific embodiments, the running state of the state machine includes an execution state, a chip analysis state, a signal analysis state, and a component analysis state. Specifically, the execution state refers to the state in which the mechanical equipment executes relevant operation instructions, the chip analysis state refers to the state in which the chip analyzes the received instructions, feedback data and other information, and the signal analysis state refers to the state in which the received external signal is analyzed.

[0069] In another specific embodiment, the debugging state of the state machine includes a start debugging state, an end debugging state, an electric roller forward debugging state, an electric roller reverse debugging state, and an electric roller stop state.

[0070] In another embodiment, the input signal includes at least a system interaction signal and an external interaction signal.

[0071] Exemplarily, the input signal includes at least a system interaction signal and an external interaction signal, wherein the system interaction signal is used to implement interactive control inside the chip, and the external interaction signal is used to implement interactive control between the chip and an external control device.

Among them, the safety control signal, the emergency stop signal, the enable signal, and the reset signal are sent by the processor inside the computer to the programmable logic device, and the operation mode feedback signal is sent by the programmable logic device to the processor to feedback whether the programmable logic device is operating normally; the interrupt signal and the prompt signal are used to realize the switching of the connection state between the processor and the programmable logic device.

[0073] In another specific embodiment, the external interactive signal of this embodiment includes an electric roller prompt signal, a transmission object arrival signal, an upstream component removal signal, a move-in execution signal, a move-in delay signal, a move-in timeout signal, a move-in execution result output signal, a weighing start signal, a weighing success signal, a downstream component move-in signal, a move-out execution signal, a downstream feedback signal, a move-out execution signal, an electric roller forward rotation signal, and an electric roller reverse rotation signal.
