s10: and a plurality of sets of equipment identity marks are stored in advance.
In particular implementations, the slave devices are directed to different types, including memory devices, control devices, and the like. Wherein, the above multiple sets of equipment identity marks can be stored through a storage device. It is understood that, in this embodiment, the type of the device id is not limited, and mainly depends on the relevant information of the device itself, such as the manufacturer address and the product address. The slave device stores the default device identification when the slave device leaves the factory, and the default device identification of the slave device is random, and the possible situations of the default value are stored in the slave device, so that various possibilities are given.
S11: and receiving the target equipment identity sent by the master equipment.
The master device and the slave device communicate with each other through 2 signal lines, and the slave device receives communication data information which is sent by the master device and is provided with a target device identity through the two signal lines; when the slave receives the information from the master, the slave enters a START state.
S12: and judging whether the equipment identity is matched with the target equipment identity or not, if so, entering S13, and if not, returning to S11.
S13: the active state is entered.
In the START state, the slave device separates the highest-order 4 bits in the communication data transmitted from the master device to determine which slave device the master device is to select, that is, whether the device id matches the target device id is determined. When the device identity is matched with the target device identity, the slave device enters an ACTIVE state; when the device identity is not matched with the target device identity, the slave device returns to an IDLE state and continues to wait for the communication data information of the master device.
In S12, when analyzing the communication data information transmitted by the master device, the example is to analyze the highest 4 bits of the data center, and in other embodiments, the highest bits, the lowest bits, or the middle bits of the data may be analyzed as long as the part of information in the data can represent the device id of the slave device.
In the communication method provided by this embodiment, multiple sets of device identifiers are pre-stored in the new slave device, so that when the target device identifier sent by the master device is received, the corresponding device identifier can be found from the multiple sets of device identifiers and matched. Because the device identification marks pre-stored in the new slave device are provided with a plurality of sets, compared with the default identification marks only stored when the slave device leaves the factory, the target device identification marks in the master device can be matched with more target device identification marks in the master device, so that the target device identification marks in the master device do not need to be frequently changed, the problem that control software of the master device needs to be modified when the matching is unsuccessful in the prior art is effectively solved, the technical difficulty is reduced, and the debugging efficiency is improved.
On the basis of the above embodiment, after S13, the method further includes:
and receiving communication data which is sent by the main equipment and contains the new equipment identity.
The master device and the slave device communicate through 2 signal lines, and the slave device receives communication data information which is sent by the master device and contains a new device identity through the two signal lines; the device identity is the unique USID (device address) of the slave device.
And replacing the multiple sets of equipment identity marks with new equipment identity marks.
Since the slave devices have been set with a default device identity at initialization, they must be software programmed to ensure that each slave device is uniquely addressable. The master device programs the new slave device to enable individual programming of the slave devices on each bus. The multiple sets of equipment identity marks in the slave equipment are replaced by the new equipment identity marks, and the unique addressability of the slave equipment is realized.
It is understood that the present embodiment does not limit the type of the new device id, and mainly depends on the related information of the device itself, such as the manufacturer address and the product address.
Fig. 3 is a flowchart of a communication method applied to a master device according to an embodiment of the present disclosure. As shown in fig. 3, the method includes:
s20: and sending the target equipment identity to the slave equipment.
The master device and the slave device communicate with each other through 2 signal lines, and the master device sends communication data information with the identification of the target device to the slave device through the two signal lines.
S21: and judging whether the equipment identity in the slave equipment is matched with the target equipment identity or not, if so, entering S12, and if not, returning to S10.
S22: a signal is received that the target slave device enters an active state.
In a particular implementation, there may be multiple sets of slave devices. In S20, the master device sends device identifiers corresponding to new slave devices to all the slave devices, after receiving information sent by the master device, the slave devices need to separate the highest-order 4 bits in the communication data transmitted by the master device to determine which slave device the master device is to select, that is, determine whether the device identifiers match the target device identifiers, and when the device identifiers in the slave devices match the target device identifiers, the master device receives a signal that the set of slave devices uniquely matching the master device enters an active state. It is to be understood that the target slave device mentioned in S22 is the set of slave devices that uniquely matches the master device.
According to the communication method provided by the embodiment, when a new slave device is debugged, because a plurality of sets of device identifiers are stored in the new slave device in advance, the master device can find the corresponding device identifiers from the plurality of sets of device identifiers of the slave device and match the device identifiers, the control software of the master device does not need to be changed every time, and the device identifiers corresponding to the new slave device are directly sent to all the slave devices, so that the target device identifiers in the master device do not need to be changed frequently, the problem that the control software of the master device needs to be modified when the matching is unsuccessful in the prior art is effectively solved, a lot of additional work is reduced, the debugging difficulty is reduced, and the working efficiency is improved.
On the basis of the above embodiment, after S22, the method further includes:
and sending the communication data containing the new equipment identity to the target slave equipment.
The master device programs the new slave device to enable individual programming of the slave devices on each bus. The multiple sets of equipment identity marks in the slave equipment are replaced by the new equipment identity marks, and the unique addressability of the slave equipment is realized.
Fig. 4 is a state diagram for modifying the device identity of the slave device according to an embodiment of the present disclosure. As shown in fig. 4, when debugging a new slave device, the master device sends a target device identity corresponding to the new slave device to the slave device, and if the target device identity sent by the master device is the same as the device identity stored in the slave device, the flow of modifying the device identity passes through, the new device identity can be written in, and normal control is continued; otherwise, the current default equipment identity is not passed and maintained. It can be seen that the master device has modified the corresponding device id for the old slave device before another new slave device is commissioned, so that when commissioning the new slave device, even if the master device sends it in broadcast form to all slave devices, there is no simultaneous matching of the two slave devices, since the device id of the old slave device has been modified by the master device, each slave device being uniquely addressable. It should be noted that the number of times of modifying the device identifier of each slave device is unlimited, that is, after the default device identifier is modified, if necessary, the modified new device identifier may be modified again.
