Description

Technical Field

[0001] The present invention relates to communication technology, and in particular to a slave ID allocation method for a multi-machine system and the multi-machine system. Background Art

[0002] A multi-machine system is a system composed of two or more electronic devices. A common multi-machine system is a host connected to multiple slaves, and the host exchanges information with multiple slaves.

[0003] In a multi-machine system, the allocation of unique identifiers (IDs) for devices is a key issue, especially when large-scale deployment is required. For electronic devices with physical addresses or serial numbers, IDs can be generated based on the physical addresses or serial numbers of the electronic devices. However, adding physical addresses or serial numbers to electronic devices increases the cost of manufacturers, so some electronic devices do not have physical addresses or serial numbers. For electronic devices without physical addresses or serial numbers, an existing method is to generate IDs based on the hardware characteristics of components in the electronic device (for example, the resistance value of a resistor, the capacitance value of a capacitor, etc.).

[0004] However, the hardware features of components in multiple slaves may be the same, which means that the slave ID is no longer unique. In order to obtain a different ID, the hardware features of each slave must be different, which increases the cost of the multi-machine system. Summary of the invention

[0005] One of the technical problems solved by the present invention is to provide a method for allocating slave IDs in a multi-machine system, which does not require different hardware features for each slave, does not require an additional central server or a complex communication mechanism, and reduces the cost of the multi-machine system.

[0006] The second technical problem solved by the present invention is to provide a multi-machine system for executing the slave ID allocation method of the multi-machine system of the present invention, which does not require different hardware features for each slave, does not require an additional central server or complex communication mechanism, and reduces the cost of the multi-machine system.

[0007] The first technical problem mentioned above is solved by the following technical solution:

[0008] A method for allocating slave IDs of a multi-machine system, the multi-machine system comprising a host and a plurality of slaves, the plurality of slaves being all provided with the same charge-discharge circuit, the charge-discharge circuit having a characteristic of non-fixed charge-discharge power, the method comprising:

[0009] The multiple slaves execute the same power management logic;

[0010] After the slave executes the power management logic, obtaining evaluation parameters of the execution of the power management logic;

[0011] Based on the evaluation parameters, the master assigns an ID to the slave.

[0012] The present invention provides a slave ID allocation method for a multi-machine system, wherein the multi-machine system includes a host and multiple slaves, wherein the slaves are provided with a charge-discharge circuit, and the charge-discharge circuit has the characteristic that the charge-discharge power is not fixed. When multiple slaves execute the same power management logic, since the charge-discharge circuit has the characteristic that the charge-discharge power is not fixed, the evaluation parameters for executing the power management logic will be different, and thus the IDs generated based on different evaluation parameters will also be different. The present invention utilizes the characteristic that the charge-discharge power of the original charge-discharge circuit of each slave is not fixed, and determines the ID of the slave through the difference in the evaluation parameters for executing the power management logic of each slave, without setting different hardware features for each slave, without requiring an additional central server or a complex communication mechanism, thereby reducing the cost of the multi-machine system.

[0013] In some embodiments of the present invention, the power management logic is charging to a first preset value or discharging to a second preset value or a preset number of charge and discharge cycles, and the evaluation parameter is execution time.

[0014] In some embodiments of the present invention, the power management logic is a first preset time for charging, a second preset time for discharging, or a third preset time for a charge-discharge cycle, and the evaluation parameter is a current power.

[0015] In some embodiments of the present invention, based on the evaluation parameter, the host assigns an ID to the slave, including:

[0016] The slave calculates the interval time for sending ID allocation request to the host according to the evaluation parameter;

[0017] The slave sends an ID allocation request to the host after the interval time;

[0018] When receiving the ID allocation request, the host determines a receiving order of the received ID allocation request;

[0019] The host determines the ID of the slave based on the order in which the received ID allocation requests are received;

[0020] The host sends ID allocation response information to the slave to allocate an ID to the slave, and the ID allocation response information includes the ID of the slave.

[0021] In some embodiments of the present invention, calculating the interval time of sending the ID allocation request to the host according to the evaluation parameter includes:

[0022] Calculate the order number of sending ID allocation requests to the master based on the evaluation parameter and the total number of the slaves;

[0023] The product of the sequence number and the preset time length is calculated to obtain the interval time for the slave to send the ID allocation request to the host, wherein the interval time is based on the broadcast signal received by the slave from the host.

[0024] In some embodiments of the present invention, calculating the order number of sending the ID allocation request to the master based on the evaluation parameter and the total number of the slaves includes:

[0025] Converting the evaluation parameter into a dimensionless value having one digit greater than the total number of the slaves;

[0026] Calculating the remainder of the dimensionless value and the total number of the slaves;

[0027] The remainder is added by 1 to obtain the sequence number of the ID allocation request sent by the slave to the master.

[0028] In some embodiments of the present invention, the slave ID allocation method of the multi-machine system further includes:

[0029] When the host simultaneously receives the ID allocation requests sent by at least two target slaves, it determines that there is a conflict between the IDs of the at least two target slaves, and does not send the ID allocation response information to the at least two target slaves.

[0030] In some embodiments of the present invention, the slave ID allocation method of the multi-machine system further includes:

[0031] After the host sends the ID allocation response information to the slaves other than the target slave, it determines that the slaves other than the target slave have been allocated IDs, the current round of ID allocation ends, and the next round of ID allocation begins;

[0032] The target slave, based on not receiving the ID allocation response information within the set time, controls the charge and discharge circuit to discharge or charge back to meet the initial conditions for executing the power management logic, and then returns to execute the same power management logic. After executing the power management logic, an evaluation parameter for executing the power management logic is obtained, and the interval time for sending an ID allocation request to the host is calculated according to the evaluation parameter, until all slaves have been assigned an ID, wherein the slave that has been assigned an ID no longer participates in the next round of ID allocation.

[0033] In some embodiments of the present invention, when the host does not receive an ID allocation request from the slave in consecutive preset rounds of ID allocation, it is determined that all the slaves have been allocated IDs.

[0034] In some embodiments of the present invention, the multiple slaves execute the same power management logic, including:

[0035] After the multi-machine system is powered on, the host sends a broadcast signal to the multiple slaves;

[0036] The multiple slave devices execute the same power management logic based on the first reception of the broadcast signal.

[0037] In some embodiments of the present invention, based on the evaluation parameter, the host assigns an ID to the slave, including:

[0038] The slave sends an ID allocation request characterized by evaluation parameters to the host;

[0039] The host determines the ID of the slave based on the evaluation parameter in the received ID allocation request;

[0040] The host sends ID allocation response information to the slave to allocate an ID to the slave, and the ID allocation response information includes the ID of the slave.

[0041] The above second technical problem is solved by the following technical solution:

DETAILED DESCRIPTION

[0052] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0053] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0054] Figure 1 The present invention provides a flowchart of a slave ID allocation method for a multi-machine system, wherein the multi-machine system includes a host and multiple slaves, wherein the multiple slaves are connected to the host, and each of the slaves is provided with a charge-discharge circuit, wherein the charge-discharge circuit has a characteristic of non-fixed charge-discharge power, such as Figure 1As shown, the method specifically comprises the following steps:

[0055] S101. Multiple slave devices execute the same power management logic.

[0056] In the embodiment of the present invention, when it is necessary to assign an ID to a slave, the host can control multiple slaves to execute the same power management logic, ensuring that the evaluation parameters of the power management logic executed by each slave are obtained when other variables are the same.

[0057] S102: After the slave executes the power management logic, it obtains evaluation parameters of executing the power management logic.

[0058] In the embodiment of the present invention, after executing the power management logic, the slave device obtains the evaluation parameter of executing the power management logic.

[0059] Exemplarily, in some embodiments of the present invention, the power management logic is that the charge and discharge circuit of the slave machine charges from the same power to a first preset value or discharges to a second preset value or a preset number of charge and discharge cycles, and the evaluation parameter is the execution time. Exemplarily, the first preset value can be any value between 80% power and 100% power, and the second preset value can be any value between 10% power and 20% power. The evaluation parameter is the charging time taken by the charge and discharge circuit of each slave machine to charge from the same power to the first preset value, or the discharge time taken by the charge and discharge circuit of each slave machine to discharge from the same power to the second preset value, or the cycle time taken by the charge and discharge circuit of each slave machine to go through a preset number of charge and discharge cycles from the same power.

[0060] Exemplarily, in some other embodiments of the present invention, the power management logic is that the charge and discharge circuit of the slave machine charges the same amount of power for a first preset time or discharges for a second preset time or charges and discharges for a third preset time, and the evaluation parameter is the current power, which is the power after the power management logic is executed.

[0061] S103. Based on the evaluation parameters, the host allocates an ID to the slave.

[0062] In some embodiments of the present invention, the slave calculates characteristic information characterizing the slave ID based on evaluation parameters, and then sends the characteristic information to the host in the form of an ID allocation request. After receiving the ID allocation request, the host determines the slave ID based on the characteristic information, and the slave sends ID allocation response information to allocate an ID to the slave, and the ID allocation response information includes the slave ID.

[0063] In other embodiments of the present invention, the slave sends an ID allocation request characterized by evaluation parameters to the host, the host determines the ID of the slave based on the evaluation parameters in the received ID allocation request, the host sends ID allocation response information to the slave to allocate an ID to the slave, and the ID allocation response information includes the ID of the slave.

[0064] The present invention provides a slave ID allocation method for a multi-machine system, wherein the multi-machine system includes a host and multiple slaves, wherein the slaves are provided with a charge-discharge circuit, and the charge-discharge circuit has the characteristic that the charge-discharge power is not fixed. When multiple slaves execute the same power management logic, since the charge-discharge circuit has the characteristic that the charge-discharge power is not fixed, the evaluation parameters for executing the power management logic will be different, and thus the IDs generated based on different evaluation parameters will also be different. The present invention utilizes the characteristic that the charge-discharge power of the original charge-discharge circuit of each slave is not fixed, and determines the ID of the slave through the difference in the evaluation parameters for executing the power management logic of each slave, without setting different hardware features for each slave, without requiring an additional central server or a complex communication mechanism, thereby reducing the cost of the multi-machine system.

[0065] It is understandable that there are many reasons why the charging and discharging circuit has the characteristic of non-fixed charging and discharging power. First, the charging and discharging circuit may be in different environmental conditions (temperature, humidity, etc.) when charging and discharging. The environmental conditions will cause fluctuations in the charging and discharging power. At the same time, the working efficiency of the components will not always remain constant. In addition, the marking parameters of the charging and discharging circuits of each slave may be the same, but due to production process reasons, the marking parameters are not completely equal to the actual parameters, that is, the actual parameters of the charging and discharging circuits of each slave are not exactly the same, which makes the charging power of the charging and discharging circuits of each slave different.

[0066] In order to enable those skilled in the art to more clearly understand the technical solution of the present invention, the solution of the present invention will be described below through specific embodiments. Exemplarily, in this embodiment, the power management logic is that the charging and discharging circuits of the slaves are charged from the same power to the first preset value, and the evaluation parameter is the charging time taken for the charging and discharging circuits of each slave to charge from the same power to the first preset value as an example. Other power management logic and evaluation parameter solutions can refer to the solution of this embodiment, and the embodiments of the present invention will not be repeated here.

[0067] Figure 2 A flowchart of another method for allocating slave IDs in a multi-machine system provided by the present invention is shown in FIG. Figure 2 As shown, the slave ID allocation method of the multi-machine system includes:

[0068] S201. Multiple slave devices execute the same power management logic.

[0069] In an embodiment of the present invention, when the multi-machine system is powered on, the master sends a broadcast signal to all slaves at a preset interval, and the slave starts to execute the power management logic when it receives the broadcast signal for the first time. Exemplarily, the charge and discharge circuits of each slave start charging from the same power. Exemplarily, the charge and discharge circuit can be a circuit including an electrolytic capacitor, and charging the charge and discharge circuit of the slave is charging the electrolytic capacitor.

[0070] S202: The slave device obtains the charging time of the charging and discharging circuit.

[0071] In an embodiment of the present invention, the slave obtains the charging time of the charge-discharge circuit to charge to a first preset value. Exemplarily, a detection circuit is provided inside the slave for detecting the voltage of the charge-discharge circuit. When the voltage of the charge-discharge circuit reaches the first preset value, it is determined that the charging of the charge-discharge circuit is completed. The slave will start timing from the first receipt of the broadcast signal to the time when it is determined that the charging of the charge-discharge circuit is completed as the charging time of the charge-discharge circuit. It should be noted that the marking parameters of the charge-discharge circuits of each slave may be the same. When the marking parameters are not completely equal to the actual parameters due to production process reasons, that is, the charge-discharge circuits of each slave have the characteristic of non-fixed charge-discharge power, the actual parameters of the charge-discharge circuits of each slave are not exactly the same, which makes the charging time of the charge-discharge circuits of each slave different.

[0072] S203: The slave calculates the interval time for sending ID allocation requests to the host according to the charging time.

[0073] As mentioned above, the charging time of the charging and discharging circuits of each slave is different. Therefore, in an embodiment of the present invention, the slave can calculate the interval time for sending an ID allocation request to the host according to the charging time, and send the ID allocation request to the host after the interval time. When the host receives the ID allocation request, it determines the ID of the slave according to the receiving order of the received ID allocation requests.

[0074] Exemplarily, in some embodiments of the present invention, the slave calculates the interval time for sending an ID allocation request to the host according to the charging time, including the following sub-steps:

[0075] S2031. Calculate the sequence number of sending ID allocation requests to the host based on the charging duration and the total number of slaves.

[0076] In an embodiment of the present invention, the sequential number of ID allocation requests sent by the slave to the host is related to the charging time of the slave and the total number of slaves in the multi-machine system. Therefore, the charging time of the slave can be dimensionless in advance, and the sequential number of ID allocation requests sent to the host can be calculated based on the dimensionless value of the charging time and the total number of slaves.

[0077] In some embodiments of the present invention, the charging time is converted into a dimensionless value that is one digit greater than the total number of slaves, the remainder of the dimensionless value and the total number of slaves is calculated, and the remainder is added by 1 to obtain the sequence number of ID allocation requests sent by the slave to the host.

[0078] Exemplarily, in a specific embodiment of the present invention, the total number of slaves in a multi-machine system is 30, and the charging time of the slaves is usually tens of milliseconds. Assuming that the charging time of one of the slaves is 54.2 ms, the charging time is converted into a dimensionless value 542 which is one digit larger than the total number of slaves. The dimensionless value 542 is divided by the total number 30, and the remainder is 2. Then the sequence number of the ID allocation request sent by the slave to the host is 2+1=3.

[0079] S2032. Calculate the product of the sequence number and the preset time length to obtain the interval time for the slave to send an ID allocation request to the master.

[0080] In an embodiment of the present invention, the product of the sequence number and the preset duration is calculated to obtain the interval time for the slave to send an ID allocation request to the host. The interval time is based on the first time the slave receives a broadcast signal from the host when the multi-machine system is powered on, and the preset time is greater than the charging time of any charge and discharge circuit. In an embodiment of the present invention, when the multi-machine system is powered on, the host sends a broadcast signal to all slaves at the same time, that is, all slaves receive the broadcast signal at the same time. Exemplarily, the preset duration is 100ms, and the sequence number of a slave sending an ID allocation request to the host calculated in the aforementioned steps is 3, then the interval time for the slave to send an ID allocation request to the host is 300ms, that is, the ID allocation request is sent to the host 300ms after receiving the initialization signal or the broadcast signal.

[0081] S204: The slave sends an ID allocation request to the master after an interval.

[0082] In an embodiment of the present invention, the slave sends an ID allocation request to the master after an interval. For example, if the interval for a slave to send an ID allocation request to the master is calculated to be 300ms in the aforementioned steps, the slave sends an ID allocation request to the master after receiving an initialization signal or 300ms after receiving a broadcast signal.

[0083] S205. When receiving the ID allocation request, the host determines the receiving order of the received ID allocation request.

[0084] In an embodiment of the present invention, when receiving the ID allocation request, the host determines the order of receiving the received ID allocation request. Exemplarily, in some embodiments of the present invention, the host can determine the order of receiving according to the time sequence of the received ID allocation request. In other embodiments of the present invention, the ID allocation request includes the sequence number calculated in the above steps, and the sequence number is the order of receiving the ID allocation request received by the host.

[0085] S206: The host determines the ID of the slave based on the order in which the received ID allocation requests are received.

[0086] In an embodiment of the present invention, the host determines the ID of the slave based on the order of receiving the received ID allocation request. For example, if the order of receiving the ID allocation request of a slave received by the host is 3, the host determines the ID of the slave to be 03.

[0087] S207: The host sends an ID allocation response message to the slave to allocate an ID to the slave.

[0088] In the embodiment of the present invention, after the host determines the ID of the slave, it immediately sends ID allocation response information to the slave, and the ID allocation response information includes the ID of the slave.

[0089] In some embodiments of the present invention, there may be a situation where the charging time of two or more slaves is very close, resulting in the same interval time for the two or more slaves to send ID allocation requests to the host, and the two or more slaves send ID allocation requests to the host at the same time. In response to this situation, when the host receives ID allocation requests from at least two target slaves at the same time, it determines that there is a conflict in the IDs of at least two target slaves, and suspends sending ID allocation response information to the target slaves.

[0090] After the host sends an ID allocation response message to other slaves except the target slave, it determines that other slaves except the target slave have been allocated IDs, the current round of ID allocation ends, and the next round of ID allocation begins.

[0091] In the next round of ID allocation, when the charge and discharge circuit is controlled to discharge and recover to the initial condition for executing the power management logic, the step of executing the same power management logic on multiple slaves is returned until all slaves have been assigned IDs, wherein the slaves that have been assigned IDs will no longer participate in the next round of ID allocation.

[0092] Exemplarily, the host allocates IDs to the slaves in a carousel manner, and the host enters the next round of ID allocation after each round of ID allocation, waiting to receive an ID allocation request, and repeats this cycle until all slaves have been allocated IDs. Exemplarily, when the host does not receive an ID allocation request from a slave in consecutive preset rounds (e.g., 5 rounds) of ID allocation, it is determined that all slaves have been allocated IDs.

[0093] After the slave sends an ID allocation request to the host after an interval, it determines whether it has received the ID allocation response information sent by the host. If so, the slave determines that the ID allocation is successful; if not, the slave determines that the ID allocation has failed, and controls the charge and discharge circuit to discharge back to meet the initial conditions for executing the power management logic, and returns to the step of executing the same power management logic on multiple slaves until all slaves have been assigned IDs, wherein the slaves that have been assigned IDs will no longer participate in the next round of ID allocation.

[0094] The present invention further provides a multi-machine system, which is used to execute the slave ID allocation method of the multi-machine system provided by any of the aforementioned embodiments of the present invention.

Exemplarily, multiple slaves 200 are cascaded and connected to the host 100.

[0095] For example, Figure 4 As shown, the charge and discharge circuit 220 includes a capacitor EC1, a first resistor R1 and a second resistor R2, the first end of the first resistor R1 is connected to the first pin PIN1 of the controller 210, the second end of the first resistor R1 is connected to the second pin PIN2 of the controller 210, the first end of the capacitor EC1 and the second end of the second resistor R2 respectively, the second end of the capacitor EC1 is grounded, and the second end of the second resistor R2 is grounded. During the charging process of the charge and discharge circuit 220, the capacitor EC1 is charged through the first resistor R1, and during the discharging process of the charge and discharge circuit 220, the capacitor EC1 is discharged through the second resistor R2.
