- Wi-Fi can convert wired network signals into wireless signals for transmission;
- a Wi-Fi system may include an access point device and a terminal device, where one end of the access point device is connected to the wired network The other end of the connection is connected to the terminal device through a wireless channel.
- the access point device is used to convert wired signals and wireless signals. It can convert the wired signals in the wired network into wireless signals and transmit them to the terminal equipment. It can also receive terminal equipment.
- the wireless signal is converted into a wired signal and transmitted to the wired network.
- a Wi-Fi system In a Wi-Fi system, all terminal devices share air interface resources. When an access point device communicates with a terminal device, the terminal devices need to compete for air interface resources. Therefore, the reason why the terminal device is disconnected may be due to the lack of competition. Communication failure due to air interface resources may also be due to the terminal equipment being powered off or the battery running out of power and other self-failures that cannot communicate with the access point device; the existing Wi-Fi systems are mostly suitable for personal home devices.
- the point does not need to know the reason why the terminal device is disconnected, but in some new application scenarios of the Wi-Fi system, the access point device needs to know the reason for the disconnection of the terminal device; for example, Wi-Fi cameras arranged in mountains or reservoirs, these cameras It is battery-powered or solar-powered, and it is easy to interrupt the communication with the access point equipment due to power failure or battery exhaustion.
- Terminal equipment can report its power-down status by itself, which can greatly reduce maintenance costs. At the same time, how to successfully report the power-down status of terminal equipment in an interference or long-distance environment has also become an urgent problem to be solved.
- the embodiments of the present application provide a power-down alarm method and related equipment, which are used to report the power-down state of a terminal device by using a dying last word mechanism, so that the access point device can be informed of the power-down state of the terminal device in time. Power failure, so that the power failure can be reported to the gateway later, and maintenance can be performed for the power failure to save maintenance costs.
- the dying words mechanism is a monitoring and alarming method for the power supply of the equipment. Back-up batteries, etc., send the final status information of the terminal equipment. Therefore, the terminal device can use the last words mechanism to report its power-down state to the access point device, so that the access point device can know the reason for its disconnection.
- the Wi-Fi terminal device and the access point device transmit data through the wireless network.
- the terminal device When the terminal device is in a power-off state due to battery exhaustion or power interruption, it can send a dying message to the access point device;
- the point device can send the power-off status of the terminal device to the network management according to the dying words message, so that the terminal device can be maintained later; After the power-down signal is detected, the dying message is sent to the wireless access point.
- the terminal device when the terminal device receives the power-down signal, it will send a dying message to the access point device, and feedback that it is in a power-down state, so that the access point device can send the situation to the network management device. , so that the network management device can know the failure cause of the terminal device, and then maintain it, which will greatly save the maintenance cost of the terminal device.
- the sending of the last words message needs to go through a series of steps such as message construction, in-core communication, queue buffering, aggregation waiting, and air interface scheduling, if the terminal device assembles and sends the message after monitoring the power-down signal, it will be very difficult to send the message. It is possible that the message is not yet assembled and the power of the energy storage components is exhausted. At the same time, if the normal management message or data message is sent, the air interface competition is fierce or the terminal device and the access point device are sent. In the case of a long distance, the packet is likely to be lost and cannot be successfully transmitted to the access point device, which eventually leads to the failure to report the power-down state of the terminal device.
- FIG. 1 is a schematic flowchart of a power failure alarm method provided by an embodiment of the present application. As shown in FIG. 1 , the power failure alarm method includes:
- the dying last words message In order to ensure that the dying last words message is sent successfully, it is necessary to assemble the dying last words message in advance before the power-down signal is detected. In this way, after the power-down signal appears, the dying last words message can be sent immediately; in this way, the terminal failure is avoided. The power of the energy storage components has been exhausted before the message is assembled after power-on.
- the terminal device after the terminal device is powered on, it can start to assemble the last words message in advance.
- the last words message is used to indicate that the terminal device is in a power-down state, and then the assembled last words message is stored; the terminal device starts Monitor the battery status, and send the power-down signal immediately after detecting the power-down signal. In this way, before the terminal device is powered down, the time required to assemble the last word message is reduced, and the success rate of message transmission is improved.
- the dying last words message includes management frame messages and data frame messages. Frame packets are sent through the management frame queue, and data frame packets are sent through the data frame queue. The following describes the management frame message and the data frame message respectively:
- the higher transmission power of the management frame can overcome the power loss in the wireless network.
- the success rate of the management frame transmission will be higher.
- the access point device can send a management frame request to the terminal device, and the terminal device responds to the request and sends a management frame reply to the access point device to complete the connection. Communication between ingress devices and end devices.
- the terminal device when the terminal device is disconnected from the access point device, the terminal device can send a deauthentication deauth management frame to the access point device; therefore, when the terminal device is in a power-down state, the deauth management frame can be used to carry the terminal device.
- the power-down state of the device constitutes a dying message.
- the reserved field in the deauth management frame can be used to indicate the power-down state of the terminal device.
- an identification field may be extended in the reserved field of the deauth management frame to indicate the power-down state of the terminal.
- a certain reserved field is determined as a power-down state indicating bit. It means that the terminal is in a power-down state. When the reserved field is 0, it means that the terminal is not in a power-down state; when the terminal is powered on, the deauth management frame can be pre-assembled, and the value of the reserved field that reflects the power-down state is determined as 1. Then encapsulate it to determine that it is a dying last word message. When the terminal is in a power-down state, it will send the dying last word message, and then the access point device will detect the received dying last word message. The state of the terminal device is obtained by reflecting the value of the reserved field in the power-down state.
- the sending rate of the data frame is relatively high, which can realize fast transmission in the wireless network, reduce the interference of other signals in the wireless network, and improve the success rate of sending the last words message.
- the terminal device when the terminal device uses two forms of frames to assemble the dying words message, it can more effectively report the power-down state of the terminal device, and improve the probability that the access point device learns the power-down state of the terminal; wherein,
- the management frame message can be sent through the management frame queue, and the data frame can be sent through the data frame queue.
- the terminal device can also preset a special queue for the dying words message, that is, the special queue does not send other messages, but is only used to send the dying words. In this way, the dying words message can be sent quickly and effectively, the waiting time for sending the message can be reduced, and the success rate of sending the message can be improved.
- the terminal device determines the priority levels corresponding to the multiple data frame queues.
- VO queue in which the VI queue is used to transmit video data, and the VO queue is used to transmit voice data.
- the priority of VI queue is higher than that of VO queue, so the data frames in VI queue are compared with the data frames in VO queue. Send first.
- the terminal device determines the target data frame queue according to the priority level.
- the terminal device needs to select a data frame queue with a high priority for sending.
- the data frame queue with the highest priority may be selected as the target data frame queue, and the target data frame queue is used to send data frame messages when the terminal device is in a power-down state, so as to improve the success rate of dying last words message sending.
- the terminal device can select the target data frame queue immediately after being powered on, that is, step 101 and steps 102 and 103 can be performed at the same time, and there is no sequence relationship.
- the terminal device detects a power-down signal.
- the power-off signal can be a power-off alarm signal of the terminal device, that is, an alarm signal issued when the terminal device is powered off or the battery is exhausted; When this value is reached, it indicates that the terminal device is about to be in a power-down state, and a power-down signal is sent at this time, instructing the terminal device to send a dying message to the access point device to report its own power failure.
- the terminal device clears the management frame messages to be sent in the management frame queue.
- a terminal device when a terminal device sends a management frame message through the management frame queue, it needs to clear other management frame messages in the management frame queue; since the terminal device sends the messages in the order of the management frame messages in the queue, In order to ensure that the terminal device sends the last words message before the power is completely cut off, the waiting time for sending the last words message should be reduced. Therefore, the previous messages to be sent in the queue can be emptied. It can be sent directly without waiting, further improving its sending success rate.
- the terminal device adds the management frame message to the cleared management frame queue.
- the management frame message is added to the empty management frame queue, and the management frame message is sent out through the sending window of the management frame queue.
- the terminal device adds the data frame message to the target data frame queue.
- the terminal device sends the data frame message through the target data frame queue, and can send the data frame message preferentially, so that the dying last word message can be sent out quickly, and the success rate of its sending is improved.
- the terminal device can perform step 106 and step 107 at the same time, that is, the steps of adding the management frame message to the management frame queue and adding the data frame message to the data frame queue are independent of each other, and there is no sequential order.
- the terminal may first add the management frame message to the management frame queue, or may first add the data frame message to the data frame queue, or both may be performed simultaneously, which is not specifically limited.
- the processing chip of the terminal device may also separately provide a hardware queue for sending specific service packets.
- the sending priority of the hardware queue may be higher than that of other queues.
- the chip provides a special preset interface to bypass other protocol stacks and buffer queues. In this way, steps such as inter-core communication, queue buffering, and aggregation waiting required for normal message transmission are omitted. Thereby, the packet sending efficiency of the dying last words message is improved.
- the terminal device simultaneously sends the management frame message and the data frame message to the wireless access point through the management frame queue and the data frame queue.
- the terminal device can send two forms of dying messages through the management frame queue and the data frame queue at the same time, so as to improve the probability that the access point device receives the dying message;
- the management frame queue and the data frame queue can be configured as Cyclic transmission, that is, the terminal device does not pay attention to the reception of the access point device, but keeps sending. Multiple transmissions can improve the success rate of the access point device receiving packets, so that the power-down state of the terminal can be known by the access point device. , thereby improving the reporting success rate of dying last words.
- the management frame queue and the data frame queue are the buffer queues of the terminal device, which are the "sending window" of the message, and there is a wireless communication channel between the terminal device and the access point device; generally, the terminal device When communicating with an access point device, it is necessary to detect the idle channel evaluation values of multiple transmission channels to obtain the busyness of each communication channel, but when the idle channel evaluation value of a communication channel is greater than the idle channel evaluation threshold, it means that The air interface corresponding to the communication channel has strong competition and interference, and the terminal device does not select this communication channel for communication; however, in this embodiment, in order to improve the success rate of sending the last words message, the transmission channel needs to transmit the last words message even if the transmission channel is busy. Therefore, the terminal device needs to increase the idle channel evaluation threshold of the transmission channel, so that the terminal can select more communication channels, and can send the dying message through multiple transmission channels to improve the success rate of sending the message.
- the terminal device transmits the dying words message through the management frame queue and the data frame queue at the same time, and at the same time accompanies other sending sets, so as to improve the success rate of sending the dying words message as much as possible, so that the access point device knows the terminal device.
- the power-off state of the device provides a prerequisite for the subsequent maintenance of the terminal equipment and reduces the maintenance cost of the terminal equipment.
