Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0066] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0067] Figure 1 A schematic diagram of a communication configuration system provided in an embodiment of the present application, wherein Figure 1 As shown, the communication configuration system may include a host device and at least one slave device, the host device is provided with a constant current source, each slave device is provided with a voltage sampling unit, the positive electrode of the constant current source in the host device is connected in series with the input end of the voltage sampling unit in each slave device, and the negative electrode of the constant current source is connected in series with the output end of the voltage sampling unit in each slave device, and optionally, the voltage sampling unit includes at least one of the following: a resistor, a voltage regulator, and a semiconductor triode. Based on the communication configuration system, a corresponding communication address can be set for each slave device, and the specific setting process can be referred to the following embodiment.

[0068] Figure 2 A flow chart of a communication address configuration method provided in an embodiment of the present application, the execution subject of the method may be a slave device in the above communication configuration system, such as Figure 2 As shown, the method may include:

[0069] S101 . When a constant current source is powered on, a voltage value corresponding to a slave device is acquired based on a voltage sampling unit.

[0070] The essence of the constant current source is to use a constant current device to feedback the current and dynamically adjust the power supply state of the device so that the current tends to be constant. As long as the current can be obtained, feedback can be effectively formed to establish a constant current source. Optionally, the constant current source device can include electronic components such as diodes and triodes, which are not limited here.

[0071] In some embodiments, the voltage sampling unit may include electronic components such as resistors and voltage regulators. Based on the connection relationship between the slave device and the host device in the above communication system, it can be seen that the constant current source can output a constant current to each slave device when powered on. By utilizing the principle of constant current source current, according to Ohm's law, through the voltage drop, the voltage value corresponding to each slave device will be different, that is, each slave device can obtain its corresponding voltage value. It can be understood that for each slave device, the voltage value obtained will be unique.

[0072] Optionally, the constant current source may be powered by a power supply system of the host device, or may be powered by a power supply system dedicated to the constant current source, which is not limited here.

[0073] S102 . Obtain a target communication address of the slave device according to a voltage value corresponding to the slave device and a preset mapping relationship, where the preset mapping relationship includes a mapping relationship between a voltage value and a communication address.

[0074] Among them, the preset mapping relationship can be pre-stored in each slave device. Then, for each slave device, after determining its corresponding voltage value, it can query and determine the communication address corresponding to each voltage value from the preset mapping relationship as the target communication address of each slave device.

[0075] S103, setting the communication address of the slave device as the target communication address.

[0076] For the slave device, based on the determined target communication address, its communication address can be set as the target communication address. It can be seen that in this setting process, the slave device can realize the automatic setting of its target communication address, which can improve the address configuration efficiency and avoid communication address setting errors; in addition, the setting of the communication address of each slave device can be made independent of the program logic in the host device, which can improve the flexibility of the communication address configuration method.

[0077] In summary, an embodiment of the present application provides a communication address configuration method, which can be applied to a slave device in a communication configuration system. The communication configuration system includes a host device and at least one slave device, a constant current source is provided in the host device, and a voltage sampling unit is provided in each slave device. The positive electrode of the constant current source in the host device is connected in series with the input end of the voltage sampling unit in each slave device, and the negative electrode of the constant current source is connected in series with the output end of the voltage sampling unit in each slave device. The method includes: when the constant current source is powered on, obtaining a voltage value corresponding to the slave device based on the voltage sampling unit; obtaining a target communication address of the slave device according to the voltage value corresponding to the slave device and a preset mapping relationship, and the preset mapping relationship includes a mapping relationship between the voltage value and the communication address; setting the communication address of the slave device as the target communication address can realize automatic setting of the communication address of the slave device, improve the address configuration efficiency, and avoid communication address setting errors; in addition, the setting of the communication address of each slave device can also be made independent of the program logic in the host device, which can improve the flexibility of the communication address configuration method.

[0078] It should be noted that, during implementation, the program logic corresponding to the above steps S101 to S103 can be deployed separately as a script program, that is, the program logic corresponding to the above steps S101 to S103 and the normal working logic corresponding to the slave device can be deployed separately to avoid affecting the implementation of other normal operations in the slave device.

[0080] Alternatively, if Figure 3 As shown, the above method also includes:

[0081] S201, receiving a query instruction sent by a host device according to a preset mapping relationship.

[0082] Optionally, the host device can pre-store the above-mentioned preset mapping relationship, that is, the mapping relationship between the voltage value and the communication address. That is, for the host device, it can pre-determine the communication address of each slave device according to the preset mapping relationship, and send a query instruction to each slave device to determine whether each slave device is online.

[0083] S202, according to the inquiry instruction, send an inquiry response to the host device, so that the host device determines the number of slave devices in the communication configuration system according to the inquiry response, and generates a slave address table for storage, the slave address table includes: the target communication address of each slave device corresponding to the inquiry response.

[0084] For each slave device, if it receives an inquiry instruction sent by the host device according to a preset mapping relationship, it can send a corresponding inquiry response to the host device. It can be understood that if the host device receives an inquiry response sent by a slave device pointed to by a certain communication address, it means that the slave device is online, otherwise, it means that the slave device is offline. It can be understood that based on this concept, the host device can receive an inquiry response sent by a communicative slave device, and determine the number of slave devices in the communication configuration system based on this, and generate a slave address table.

[0085] Among them, the generated slave address table can include the target communication address of each slave device. It can be understood that when the host device subsequently communicates with a specific slave device, the target communication address of each slave device can be determined according to the slave address table to achieve accurate communication.

[0086] Optionally, in some embodiments, after generating the above-mentioned slave address table, the host device may also power off the constant current source to avoid ineffective waste of electric energy, thereby reducing the address configuration cost.

[0087] Optionally, the communication configuration system also includes at least one slave power system, and each slave power system power supply output terminal is electrically connected to the power supply input terminal of each slave device, so that for each slave device, it can also have its exclusive slave power system to power the controller therein, ensuring the reliability of the working power supply of the slave device. In some embodiments, the slave power system of each slave device can be arranged inside the slave device. Applying the embodiments of the present application, it is possible to be compatible with slave devices with a slave power system arranged inside, and the applicability of the method of the present application can be improved.

[0088] Of course, it should be noted that each slave device may also share a power supply system, and the power supply system may be arranged inside the host device, thus reducing the manufacturing cost of each slave device.

[0089] In some embodiments, the slave devices include multiple slave devices, and a preset mapping relationship is pre-stored in the host device. The preset mapping relationship also includes a mapping relationship between the communication address of each slave device and the arrangement order. The arrangement order is used to indicate the arrangement order of each slave device among the multiple slave devices.

[0090] In combination with the above description, the preset mapping relationship stored in the host device may include a mapping relationship between a voltage value, a communication address, and an arrangement order, wherein the arrangement order may indicate the arrangement order of each slave device among multiple slave devices, that is, it may indicate the installation position of each slave device among multiple slave devices.

[0091] By applying the embodiments of the present application, if the operation and maintenance personnel of the slave device determine that a certain slave device has a fault at the working site of the slave device, then at this time, the arrangement order of the slave device among multiple slave devices can be obtained and input into the host device, and the host device determines the communication address of the slave device according to the arrangement order corresponding to the slave device, and sends a corresponding fault query instruction to the communication address of the slave device; for the slave device, optionally, after receiving the fault query instruction sent by the host device, it can return relevant status parameters to the host device, so that the slave device can quickly determine the cause of the failure of the slave device according to the relevant status parameters, thereby improving the applicability and intelligence of the method of the present application.

[0092] Figure 4 A flowchart of another communication address configuration method provided in an embodiment of the present application. Optionally, the host device performs serial communication with each slave device based on a serial communication protocol, wherein the serial communication protocol may be an RS485 protocol, a serial peripheral interface (Serial Peripheral Interface) protocol, an integrated circuit bus (Inter-Integrated Circuit, IIC), etc., which is not limited here and can be flexibly selected according to the actual application scenario.

It should be noted that the serial communication connection mode between the slave devices can refer to the connection mode between the host device and the slave device mentioned above, which will not be repeated here.

[0094] Based on the above description, if Figure 4 As shown, the above-mentioned receiving the query instruction sent by the host device according to the preset mapping relationship includes:

[0095] S301, receiving, through a first serial receiving end, a query instruction sent by a host device through a second serial sending end.

[0096] Accordingly, the above-mentioned sending of the inquiry response to the host device according to the inquiry instruction includes:

[0097] S302: According to the inquiry instruction, send an inquiry response to the host device through the first serial sending end.

[0098] Among them, according to the communication connection relationship between the above-mentioned host device and the slave device, the host device can send an inquiry instruction to the slave device connected to it through the second serial transmitting end, and the slave device can receive the inquiry instruction sent by the host device according to the preset mapping relationship through the first serial receiving end, and send an inquiry response to the host device through the first serial transmitting end; the host device can receive the inquiry response through the second serial receiving end, so that normal communication between the host device and the slave device can be achieved.

[0099] It should be noted that, if the communication configuration system includes multiple slave devices, each slave device may communicate with the host device with reference to the above steps S301 and S302.

[0117] Based on the above description, it can be seen that the present application can generate constant current source power-on instructions in a variety of ways, so that different generation methods can be selected according to actual application scenarios, which can improve the applicability of the method of the present application.

[0118] Based on the above embodiment, it should be noted that if a new addition operation is performed on a slave device in the communication configuration system, in this case, in order to ensure that the newly added slave device can be assigned to the correct target communication address, the above steps S101 to S103 can be re-executed, that is, the constant current source can be controlled to be powered on again, so as to ensure that each slave device can be assigned to the correct target communication address. It is worth noting that if a deletion operation is performed on a slave device in the communication configuration system, it is also necessary to re-execute the above steps S101 to S103 so that the slave address stored in the host device can be updated in time.

[0119] Optionally, the host device includes a gateway, and the slave device includes at least one of the following: a circuit breaker, a contactor, and a relay.

[0120] It should be noted that if the communication configuration system includes multiple slave devices, the multiple slave devices may optionally include at least two types of devices. For example, among the multiple slave devices, some of the slave devices are circuit breakers, and some of the slave devices are relays.

[0121] Of course, it should be noted that the types of slave devices are not limited to the types shown above, and may also include fuses, leakage protectors, air switches, etc. according to actual application scenarios. The host device is also not limited to the gateway, and may also be an industrial computer, a portable computer, etc. according to actual application scenarios.

[0122] Optionally, an embodiment of the present application further provides a distribution box, which may include the above-mentioned communication configuration system. For the description of the communication configuration system, please refer to the relevant part mentioned above and will not be repeated here.

[0123] In some embodiments, each slave device may be provided with a default address. Optionally, the default address may be set at the factory. During the communication address configuration process, the host device may communicate with each slave device in sequence according to the default address and the communication order of each slave device, and send a target communication address to each slave device. After receiving the target communication address, each slave device may reset its own communication address accordingly, wherein the target communication address may be determined according to the communication address setting rules, and the target communication addresses corresponding to each slave device are different. For example, the default address of each host device may be M. Using the embodiments of the present application, for example, the target communication address of the first slave device communicating with the host device may be set to A, and the target communication address of the Nth slave device communicating with the host device may be set to A+N. Of course, the communication address setting rules are not limited to this.

[0124] In some embodiments, the host device may also determine the target communication address of each slave device according to the communication signal strength between the host device and some slave devices and a preset algorithm.

[0125] Alternatively, a power IO signal line can be added to establish hand-in-hand communication between a slave device and the remaining slave devices through high and low levels. Optionally, during the specific setting, the host device can set one slave device to correspond to a high-level signal each time and the other slave devices to correspond to low-level signals. For the slave device marked as a high-level signal, the host device determines the target communication address of the slave device according to the communication address setting rule, and sets the communication address of the slave device accordingly.

[0130] The preset mapping relationship includes a mapping relationship between a voltage value and a communication address.

[0131] In combination with the foregoing description, after the host device obtains the constant current source power-on instruction, it can power on the constant current source accordingly, so that the communication address setting function of each slave device can be triggered through the constant current source power-on operation, thereby realizing the automatic setting of the communication address, improving the address configuration efficiency of the slave device, and avoiding communication address setting errors; in addition, the setting of the communication address of each slave device can be made independent of the program logic in the host device, thereby improving the flexibility of the communication address configuration method.
