Technical Field

Background

In a computer system architecture with multiple device connections, one networking strategy is to deploy devices with management rights, where other devices are centrally managed by the devices with management rights. For example, in an intelligent fire protection system, a front-end device node for deploying gateway devices as devices with management authority, which are used for monitoring information such as environmental information, voltage or current in a line, and the like, can report the monitoring information to the gateway devices, and the gateway devices uniformly upload the monitoring information of each node to a platform service center.

Among the interconnected devices, the device without management authority needs to register on the device with management authority, so that the device with management authority records the device information thereof, and further performs communication.

Currently, the registration of devices is mostly realized by manually configuring the device information of each device in the devices with management authority by technicians, and then installing the devices into a system, or additionally adding a registration key in the devices. In engineering, equipment is registered into equipment with management authority one by one through manual interaction, so that the operation is troublesome, the efficiency is low, and the installation, the test and the maintenance are inconvenient.

According to the device registration method, in the process of registering the second device with the first device, the second device with the registration count value meeting the preset value sends response messages to the first device, and the first device controls the registration count value of the second device by sending a numerical value update instruction according to the received number of the first response messages, so that the received number of the second response messages sent by the second device meets the preset condition, and the registration of the second device is completed. In this way, the first equipment and the second equipment interact and control the registration count value, so that the second equipment actively registers with the first equipment without manual participation, and simple and efficient equipment registration is realized.

Wherein the preset value may be 0.

In one possible implementation manner, the determining, according to the number of received first response messages, the numerical update instruction sent to the second device may be specifically implemented as: if the received quantity of the first response message is larger than a first received quantity threshold value, determining a first numerical value updating instruction sent to the second equipment; or if the received number of the first response messages is smaller than the first received number threshold value, determining a second numerical update instruction sent to the second device. The first numerical value updating instruction is used for indicating second equipment with the registration count value meeting the preset value to update the respective registration count value, and the second numerical value updating instruction is used for indicating second equipment with the registration count value not meeting the preset value to update the respective registration count value. When the receiving quantity of the first response messages is too large, updating the registration count value of the second equipment with the registration count value meeting the preset value through a first updating instruction, reducing the quantity of the second equipment with the registration count value meeting the preset value, and improving the probability of successful registration of the second equipment by sending the second response messages; when the number of the received first response messages is too small, the registration count value of the second equipment with the registration count value not meeting the preset value is updated through the second updating instruction, the number of the second equipment with the registration count value meeting the preset value is increased, and the probability of successful registration of the second equipment through sending the second response messages is improved.

The number of times that the data transmission bus is in an idle state is smaller than a second time threshold value, which indicates that the idle degree of the data transmission bus is not large, and the registration count value of the second device with the registration count value meeting the preset value can be finely adjusted through a second updating sub-instruction so as to realize small-amplitude increase of the number of the second devices with the registration count value meeting the preset value; the number of times that the data transmission bus is in the idle state is greater than or equal to a second number of times threshold value, which indicates that the idle degree of the data transmission bus is serious, and the registration count value of the second device, which satisfies the preset value by the registration count value, can be greatly updated through a fourth updating sub-instruction, so that the number of the second devices, which satisfies the preset value by greatly increasing the registration count value, is realized.

The second device is configured with a registration count value (hereinafter referred to as Q value), the value of the registration count value is used by the second device to determine whether to send a response message to the first device, and the second device whose registration count value meets a preset value can send the response message to the first device. It should be noted that, the process of registering each second device with the first device, or the process of the first device processing registration of each second device, is the same, and the second devices described in the embodiments described below may be each second device connected to the first device and not yet successfully registered.

Fig. 3 is a flowchart of a device registration method provided in the present application, where the method may be applied to a first device, and may specifically be performed by a device registration apparatus disposed on the first device. As shown in fig. 3, the method may include:

S301, the first device sends registration instructions to a plurality of second devices.

For example, in S301, the first device may broadcast the registration instruction to the plurality of second devices, or may send the registration instruction to the plurality of second devices in other manners, which is not limited in the manner in which the first device sends the registration instruction.

Wherein, in S301, the first device may send a registration instruction to a plurality of second devices that are not currently registered. Alternatively, in S301, the first device may send a registration instruction to the second device connected to the first device, where the second device that has completed registration ignores the registration instruction, which is equivalent to the first device sending a registration instruction to a plurality of second devices that are not currently registered.

In a possible implementation, the first device may perform S301 after power-up to initiate a registration procedure of the second device connected thereto.

In one possible implementation, the registration instruction may be configured to instruct the second device that receives the registration instruction to update its registration count value to an initial value.

Wherein the initial value may be 0. Of course, the initial value may be another value, which is not specifically limited in the embodiment of the present application.

In another possible implementation, the registration instruction may include a re-registration instruction sent by the first device to a second device that has not successfully registered when there is a second device that satisfies the registration condition.

For example, the registration condition may be that the first device may successfully acquire device information of the second device, where the device information is used to complete registration of the second device with the first device.

In a possible implementation, the re-registration instruction is used to instruct the remaining unregistered second devices to update the registration count value and register with the first device, for example, may be used to instruct the second device that receives the re-registration instruction to reduce its registration count value by a first preset step. The first preset step size may be 1 or other values, which are not limited in the embodiments of the present application.

The device information of the second device may be address information of the second device or information having an identification function such as a unique serial number, and the specific form of the device information of the second device is not limited in the embodiment of the present application.

In one possible implementation, a congestion flag bit may be set in the first device, where the congestion flag bit is used to record the number of times the data transmission bus is congested.

One possibility is that in an implementation, the first device may increment the congestion flag bit by 1 each time it detects that the data transfer bus is congested.

In another possible implementation, the first device may set the congestion flag location to an initial value each time the first device sends a re-registration instruction.

Wherein the data transmission bus is used for transmitting interaction data between the first device and the second device, including but not limited to response messages, device verification identifiers and the like. The content of the data transmission bus transmission is not limited in the application.

For example, the initial value of the congestion flag may be 0 or other values, which are not limited in the embodiments of the present application. The first device may set the congestion flag position to an initial value after power-up or after transmitting a first registration instruction.

In one possible implementation, an idle flag bit may be set in the first device, where the idle flag bit is used to record the number of times the data transmission bus is idle.

One possibility is that in an implementation, the first device may increment the idle flag bit by 1 each time it detects that the data transfer bus is idle.

In another possible implementation, the first device may set the idle flag location to an initial value each time the first device sends a re-registration instruction.

For example, the initial value of the idle flag bit may be 0 or other values, which are not limited in the embodiments of the present application. The first device may set the idle flag position to an initial value after power-up or after sending a first registration request.

The data transmission bus is in an idle state, which may be a state in which the second device does not send the interaction data to the first device, and may be considered that no interaction data is transmitted in the data transmission bus.

S302, the first device determines the receiving quantity of the first response messages sent by the second devices.

Wherein the first response message is generated and transmitted by the second device in case that the registration count value satisfies a preset value.

For example, the first response message may include device information of the second device, such that the first device detects the device information and determines the reception number of the first response message based on the detection result.

Further, the first response message may further include verification mode indication information, which is used to indicate a verification mode of the transmitted device information.

For example, the check means may be a cyclic redundancy check code (cyclic redundancy check, CRC) 16.

Specifically, in S302, the first device may receive, within a preset duration after sending the registration request, the number of first response messages sent by the second device.

When the first response message includes device information of the second devices, the first device determines, in S302, a number of received first response messages sent by the plurality of second devices, which may be specifically implemented as: detecting device information in first response messages sent by a plurality of second devices; and determining the receiving quantity of the first response messages sent by the second devices according to the detection result.

For example, the first device detects the device information in the first response message successfully, and determines that the number of received first response messages sent by the plurality of second devices is 1; or the first device detects the device information in the first response message unsuccessfully, and determines that the number of the first response messages sent by the second devices is not 1.

S303, the first device determines a numerical value updating instruction sent to the second device according to the received number of the first response messages.

Specifically, in S303, the first device determines a numerical update instruction to be transmitted to the second device and transmits the determined numerical update instruction.

In a possible implementation manner, the determining, by the first device in S306, the numerical update instruction sent to the second device according to the received number of the first response messages may be specifically implemented as: if the received quantity of the first response message is larger than a first received quantity threshold value, determining a first numerical value updating instruction sent to the second equipment; or if the received number of the first response messages is smaller than the first received number threshold value, determining a second numerical update instruction sent to the second device. The first numerical value updating instruction is used for indicating second equipment with the registration count value meeting the preset value to update the respective registration count value, and the second numerical value updating instruction is used for indicating second equipment with the registration count value not meeting the preset value to update the respective registration count value.

The first receiving amount threshold may be 1 or other values, which is not limited in the embodiment of the present application, and may specifically be determined according to the computing capability supported by the first device.

Further, after S302, the method provided in the embodiment of the present application may further include: the first device counts the times that the data transmission bus is in a crowded state according to the received number of the first response messages.

For example, the first device may count the number of times the data transmission bus is in the congestion state according to the received number of the first reply messages when the received number of the first reply messages is greater than the first received amount threshold.

Specifically, in S302, the first device may count the number of times that the data transmission bus is in a congestion state according to the recorded congestion flag bit of the number of times that the data transmission bus is in a congestion state.

After counting the number of times that the data transmission bus is in a congestion state, in S303, if the number of received first response messages is the first receiving amount threshold, determining a first numerical value update instruction sent to the second device may be specifically implemented as: and if the received number of the first response messages is larger than a first received number threshold, determining a first numerical value updating instruction sent to the second equipment according to the times that the data transmission bus is in a crowded state.

It should be noted that, for the specific implementation of the first numerical value update instruction determined by the first device according to the number of times that the data transmission bus is in a congestion state, the embodiment of the present application is not limited thereto.

In a possible implementation manner, the determining, by the first device, a first numerical update instruction sent to the second device according to the number of times that the data transmission bus is in a congestion state includes: if the number of times that the data transmission bus is in a congestion state is smaller than a first time threshold, determining a first updating sub-instruction sent to the second device, wherein the first updating sub-instruction is used for indicating the second device of which the registration count value meets a preset value to randomly update the registration count value. Or if the number of times that the data transmission bus is in the crowded state is greater than or equal to the first time threshold, determining a third updating sub-instruction sent to the second device, wherein the third updating sub-instruction is used for indicating the second device with the registration count value meeting the preset value to update the respective registration count value to N times of the current value, and then adding a one-bit random number, wherein N is an integer which is not zero.

Illustratively, N may be 2.

Illustratively, the first time count threshold may be 3. Of course, the value of the first time threshold may be configured according to actual requirements, which is not limited in the embodiment of the present application.

In another possible implementation manner, the third updating sub-instruction is further configured to instruct the second device whose registration count value does not meet the preset value to update the respective registration count value to N times the current value and then add a one-bit random number.

Wherein, the registration count value is updated randomly, and the registration count value can be updated to be 1-bit random number 0 or 1. Of course, the specific implementation of the random update may be configured according to actual requirements, which is not limited in the embodiments of the present application.

Further, after S302, the method provided in the embodiment of the present application may further include: the first device counts the number of times the data transmission bus is in an idle state according to the received number of the first response messages.

For example, the first device may count the number of times the data transmission bus is in the idle state according to the received number of the first reply messages when the received number of the first reply messages is smaller than the first received amount threshold.

Specifically, the first device may count the number of times that the data transmission bus is in the idle state according to the recorded idle flag bit of the number of times that the data transmission bus is in the idle state.

After the first device counts the number of times that the data transmission bus is in the idle state, if the number of received first response messages is smaller than the first receiving amount threshold in S303, determining a second numerical value update instruction sent to the second device may be specifically implemented as: and if the received number of the first response messages is smaller than the first received number threshold, determining a second numerical value updating instruction sent to the second device according to the number of times that the data transmission bus is in an idle state.

It should be noted that, for the specific implementation of the second numerical update instruction determined by the first device according to the number of times that the data transmission bus is in the idle state, the embodiment of the present application is not limited thereto.

In a possible implementation manner, the determining, by the first device, a second value update instruction sent to the second device according to the number of times that the data transmission bus is in an idle state includes: if the number of times that the data transmission bus is in an idle state is smaller than a second number of times threshold, determining a second updating sub-instruction sent to the second device, wherein the second updating sub-instruction is used for indicating the second device of which the registration count value does not meet a preset value to randomly update the registration count value; or if the number of times that the data transmission bus is in the idle state is greater than or equal to the second number of times threshold, determining a fourth updating sub-instruction sent to the second device, where the fourth updating sub-instruction is used to instruct the second device whose registration count value does not meet the preset value to update the respective registration count value to a value obtained by rounding the quotient value of the current value and N, where N is an integer that is not zero.

Illustratively, the second time threshold may be 4. Of course, the value of the second time threshold may be configured according to actual requirements, which is not limited in the embodiment of the present application.

In another possible implementation manner, the fourth updating sub-instruction is further configured to instruct the second device whose registration count value meets the preset value to update the respective registration count value to a value obtained by rounding the current value and the quotient value of N.

In another possible implementation, if the number of times the data transmission bus is in the idle state is less than a second number of times threshold, determining a second update sub-instruction to send to the second device includes: if the number of times the data transmission bus is in the idle state is less than a second number of times threshold, and the numerical update instruction last transmitted by the first device is a random update instruction (e.g., a first update sub-instruction or a second update sub-instruction), determining a second update sub-instruction to be transmitted to the second device; or if the number of times the data transmission bus is in the idle state is smaller than the second number of times threshold, and the numerical update instruction sent by the first device last time is not the first update sub-instruction or the second update sub-instruction, determining a re-registration instruction sent to the second device, wherein the re-registration instruction is used for indicating the second device to register with the first device.

Further, if the number of received first response messages determined by the first device in S302 is equal to the first receiving amount threshold, there is a second device that satisfies the registration condition, the first device may complete the registration operation of the second device that satisfies the registration condition, and then send a prompt message to the second device that satisfies the registration condition. The prompting message is used for notifying the second device that registration is successful.

The specific content of the registration condition may be configured according to the actual requirement, which is not limited in the embodiment of the present application.

For example, it may be determined that the registration condition may be that the received number of the second reply messages is X, which is the maximum information transfer number supported by the data transfer bus between the first device and the second device.

For example, X may be 1.

S304, the first device determines the receiving quantity of the second response messages sent by the second devices.

The second response message is generated and sent by the second device when the updated registration count value or the non-updated registration count value meets a preset value.

For example, the second response message may include device information of the second device, such that the first device detects the device information, and determines the reception number of the second response message based on the detection result.

Further, the second response message may further include verification mode indication information, which is used to indicate a verification mode of the transmitted device information.

It should be noted that, in S304, the first device determines the number of received second response messages sent by the plurality of second devices, and the specific implementation of determining the number of received first response messages sent by the plurality of second devices by referring to the first device in S302 is not described herein.

Illustratively, the second reply message includes device information of the second devices, and the first device determines, in S304, a number of received second reply messages sent by the plurality of second devices, including: detecting device information in second response messages sent by a plurality of second devices; and determining the receiving quantity of the second response messages sent by the second devices according to the detection result.

For example, the first device detects the device information in the second response messages successfully, and determines that the number of received second response messages sent by the plurality of second devices is 1; or the first device detects the device information in the second response messages unsuccessfully, and determines that the number of the second response messages sent by the second devices is not 1.

The registration instruction received by the second device may be a registration instruction sent by the first device in S301. The transmission timing and content of the registration instruction are described in detail in S301, and are not described here again.

After receiving the registration instruction in S401, the second device executes S402.

S402, if the registration count value of the local machine meets a preset value, the second device sends a first response message to the first device.

The second device sends the first response message to the first device, so that the first device determines a numerical value updating instruction sent to a plurality of second devices according to the receiving quantity of the first response message.

For example, the verification may be CRC16.

S403, the second device receives the numerical value updating instruction sent by the first device.

It should be noted that, the numerical update instruction received by the second device in S403 is the numerical update instruction sent by the first device in S303.

After S403, the second device determines whether to update its own registration count value according to the function of the numerical update instruction, which may specifically include any one of the following cases:

the case 1, the numerical value updating instruction includes a first numerical value updating instruction determined by the first device when the received number of the first response messages is greater than a first received number threshold, where the first numerical value updating instruction is used for indicating the second device whose registration count value meets a preset value to update respective registration count values; after receiving the numerical update instruction sent by the first device, the second device may further include: and if the registration count value of the local machine meets the preset value, updating the registration count value of the local machine based on the first numerical value updating instruction.

In a possible implementation manner, in case 1, the numerical update instruction may further include a first numerical update instruction that is determined by the first device based on the number of times the data transmission bus between the first device and the second device is in a congestion state when the number of received first response messages is greater than the first reception amount threshold. The number of times the data transmission bus is in a congestion state is statistically derived based on the number of received first reply messages.

And 2, the numerical value updating instruction comprises a second numerical value updating instruction which is determined by the first device under the condition that the receiving quantity of the first response message is smaller than a first receiving quantity threshold value, and the second numerical value updating instruction is used for indicating the second device of which the registration count value does not meet the preset value to update the respective registration count value. After receiving the numerical update instruction sent by the first device, the second device may further include: if the registration count value of the local machine does not meet the preset value, the registration count value of the local machine is updated based on the second numerical value updating instruction.

In a possible implementation manner, in case 2, the numerical update instruction may further include a second numerical update instruction that is determined by the first device based on a number of times the data transmission bus between the first device and the second device is in an idle state, where the number of received first response messages is smaller than the first reception threshold, and the number of times the data transmission bus is in the idle state is obtained based on statistics of the number of received first response messages.

The second device sends a second response message to the first device, so that the first device determines whether the second device meeting the registration condition exists according to the receiving quantity of the second response message.

The second response message may include device information of the second device, so that the first device detects the device information and determines the number of received second response messages based on the detection result.

The device registration method provided by the application is described below by taking an interaction process of the first device and the second device as an example. As shown in fig. 5, the device registration method may include:

s501, the first device sends registration instructions to a plurality of second devices.

It should be noted that, the specific implementation of S501 is the same as S301, and will not be repeated here

S502, the second device receives a registration instruction sent by the first device.

The registration instruction received by the second device is the registration instruction sent by the first device in S501. The transmission timing and content of the registration instruction are described in detail in S501, and are not described here again.

After receiving the registration instruction in S502, the second device executes S503.

S503, the second device judges whether the registration count value of the second device meets a preset value.

Specifically, after receiving the registration instruction, if the received instruction instructs the second device to update its registration count value, the second device updates the local registration count value first, and in S503, it is determined whether the updated registration count value meets a preset value. Or after receiving the registration instruction, if the received instruction does not instruct the second device to update its registration count value, the second device determines in S503 whether the registration count value that is not updated meets the preset value.

For example, if the second device receives the first registration instruction sent by the first device when the first device is powered on in S502, the registration count value may be updated to an initial value.

For example, if the second device receives the re-registration instruction sent by the first device in S502, the registration count value may be updated to decrease by the first preset step size.

The preset value may be 0 or other values, and may be configured according to actual requirements, which is not limited in the embodiments of the present application.

Optionally, if the second device determines in S503 that the registration count value of the second device meets the preset value, S504 is executed, otherwise, the next instruction sent by the first device is waited to be received.

S504, if the registration count value of the local machine meets a preset value, the second device sends a first response message to the first device.

Note that, the specific implementation of S504 is the same as S402, and will not be described here again.

S505, the first device determines the received quantity of the first response messages sent by the second devices.

Note that, the specific implementation of S505 is the same as S302, and will not be described here again.

S506, the first device determines a numerical value updating instruction sent to the second device according to the received number of the first response messages.

Note that, the specific implementation of S506 is the same as S303, and will not be described here again.

S507, the second device receives a numerical value updating instruction sent by the first device.

Note that, the numerical update instruction received by the second device in S507 is the numerical update instruction sent by the first device in S506.

After S507, the second device determines whether to update its own registration count value according to the function of the numerical update instruction, and the specific implementation is the same as S403, which is not described herein.

S508, the second device judges whether the updated registration count value or the non-updated registration count value of the second device meets a preset value.

Specifically, after receiving the numerical value update instruction, if the received instruction instructs the second device to update its registration count value, the second device updates the local registration count value first, and in S508, it is determined whether the updated registration count value meets a preset value. Or after receiving the numerical value updating instruction, if the received instruction does not instruct the second device to update the registration count value, the second device determines in S508 whether the registration count value that is not updated meets the preset value.

Optionally, if the second device determines in S508 that the locally updated registration count value or the non-updated registration count value meets the preset value, S509 is executed, otherwise, the next instruction sent by the first device is waited to be received.

S509, if the updated registration count value or the non-updated registration count value of the local machine meets a preset value, a second response message is sent to the first device.

S510, the first device determines the receiving quantity of the second response messages sent by the second devices.

Note that, the specific implementation of S510 is the same as S304, and will not be described here again.

S511, the first device determines whether the second device meeting the registration condition exists according to the received quantity of the second response messages sent by the second devices.

Further, the device registration method provided by the present application may further include: and if the second equipment meeting the registration conditions exists, sending a prompt message to the second equipment after finishing the registration operation of the second equipment meeting the registration conditions. The second device receives the prompt message sent by the first device.

The prompt message is sent after the first device completes the registration operation of the local machine, and is used for notifying that the second device meeting the registration condition is successfully registered.

In a possible implementation manner, after the second device receives the prompt message, subsequently received registration-related instructions (the registration instruction and the numerical update instruction) are ignored.

Specifically, completing registration of the second device may include recording device information of the second device to ensure successful communication with the second device that satisfies the registration condition.

Further, after sending the prompt message to the second device, the device registration method provided in the embodiment of the present application may further include: the first device sends a re-registration instruction to the second device, and the second device which is not successfully registered is indicated to register with the first device.

Further, the device registration method provided by the present application may further include: if the second device meeting the registration condition does not exist, the first device determines a numerical value updating instruction sent to the second device according to the receiving quantity of the second response message.

It should be noted that, the specific implementation of the numerical update instruction sent to the second device by the first device according to the received number of the second response message may refer to the specific implementation of S303, which is not described herein again.

In a possible implementation manner, the registration process may be ended by setting an end flag bit in the first device, where an initial value of the end flag bit is X, where X is an integer greater than 1, and when the end flag bit is less than 0. When the first device determines that the data transmission bus is idle, it may first determine whether the end flag bit is less than 0, if the end flag bit is less than 0, it indicates that all the second devices have completed registration, and may end the registration procedure, and if the end flag bit is greater than 0, execute the procedure to continue registration of the second devices. If the end flag bit is equal to 0, the registration process can be finished or the process can be executed to continue the registration of the second device according to the design of the actual situation.

Wherein X may be 2.

In one possible implementation, after the first device sends the first numerical update instruction, the end flag bit may be increased by 1.

In another possible implementation manner, after the first device sends the third update sub-instruction, the end flag bit may be multiplied by N and then added with a one-bit random number.

In another possible implementation manner, after the first device sends the fourth update sub-instruction, the end flag bit may be updated to a value obtained by rounding the quotient of the current value and N.

In another possible implementation, after the first device sends the re-registration instruction, the end flag bit may be decremented by 1.

In another possible implementation manner, the registration process may be ended by setting a first registration success count value in the first device, adding 1 to the first registration success count value every time the registration of the second device is performed, and ending the registration process when the first registration success count value is equal to the total number of the second devices connected by the first device.

In another possible implementation manner, the registration process may be ended by setting a second registration success count value in the first device, subtracting 1 from the second registration success count value every time the registration of the second device is performed, and ending the registration process when the second registration success count value is equal to 0.

The scheme provided by the application is described below by taking a first device as an electricity consumption host device and a second device as a fire protection detection device as an example through a specific example.

Assuming that 6 fire-fighting detection devices as slaves are connected to the power-consuming master device through a 485 bus, and recorded as T0001 to T0006, respectively, an automatic registration process of T0001 to T0006 will be described below in conjunction with the device registration method illustrated in fig. 5. The power consumption host device is provided with a congestion flag CCN, an idle flag CIN, an end flag ED (initial value is 2), a congestion threshold (the first-time threshold) of 3, and an idle threshold (the second-time threshold) of 4. As shown in fig. 6, the device registration method may include:

and S601, powering up the power utilization host equipment, and sending a first query request on a 485 bus.

After S601 is executed, CCN is set to an initial value of 0, cin is set to an initial value of 0, and ed is set to an initial value of 2 in the power consumption host device.
