Description
Technical Field
The present invention relates to the field of communication control technologies, and in particular, to an apparatus status monitoring method, an apparatus status monitoring device, and a readable storage medium.
Background
With the progress of science and technology, more and more new technologies are applied to the life of people at present, and the appearance of a wireless network enables the fields of the internet of things, smart home and the like to rise rapidly. Since the technology of low power consumption Bluetooth BLE [1] and Bluetooth MESH [2], the smart home has better development. In the intelligent home field, various household devices and some detection devices, such as an intelligent lamp, an intelligent switch, an intelligent door lock and the like, can be used. When a device works, the state of the device is often required to be known, such as the states of online (power-on and normal working state processing) and offline (power-off, sleep or out-of-communication range), the signal strength of the device and the like.
Bluetooth MESH is a brand-new Bluetooth many-to-many networking technology, devices can communicate with each other and forward information in a network, and the control of the Bluetooth MESH is to ensure that the on-line state of the devices needs signals which cannot be weak, and the on-line or off-line state of the devices needs to detect information such as signal strength in real time. The online status is generally easy to implement because the device can send messages as soon as it is powered on, but is offline differently, and the device itself cannot send messages if it is offline, and therefore neither other devices nor the network configurator (provisioner) can know. To know how regularly to communicate with it, a commonly used method is to send a timed heartbeat containing some device information. The main technical scheme for realizing the heartbeat of the Bluetooth mesh equipment is as follows:
in the first scheme, a mode that equipment sends heartbeat commands at regular time is adopted. The scheme is that each device sends a heartbeat packet to a provisioner at regular time, the provisioner judges according to the time when each device receives the heartbeat, and the device is considered to be offline when the heartbeat is not received within a certain time. The bluetooth MESH protocol specification supports this approach by default.
And secondly, a mode of actively inquiring the equipment by the network configurator is adopted. The scheme is that a provider actively sends a heartbeat query command to query all devices in the whole device list, if the corresponding devices have information to return, the devices are still online, and if the devices cannot be queried for many times, the devices are offline.
In the first scheme, a standard method is adopted, and a protocol of the bluetooth mesh standard is also used in the method, but the method has a problem that concurrency is caused in one case, heartbeats of devices may be sent out simultaneously, and a great amount of heartbeat information may be received by a provider simultaneously when the provider receives the heartbeat information, so that on one hand, a probabilistic packet loss may occur, and in addition, other normal command control may be influenced, which may cause a delay in control or a command loss. And if the provider is an intelligent device which communicates through the GATT protocol and does not support MESH, the problem is further highlighted. The intelligent equipment is provided with an operating system, so that the situations of system scheduling, task switching and the like exist. And do not respond in real time, and in addition the criteria and heartbeat contain less information to know some other useful information about the device.
The second scheme is also a common mode for people, and because the second scheme is one-to-one communication, the second scheme has the advantage that the problem of heartbeat concurrence can be solved. It has the disadvantage that if the number of devices is large, the faster the polling communication will be, with a fixed heartbeat detection time, the higher the working of the provisioner device. If the provider is a gateway device supporting the mesh network or a real-time operating system, the situation is better, but for an intelligent device which does not support the mesh network to communicate by adopting a gatt (generic attribute profile) proxy protocol, a problem exists, and because the query needs to be continuously performed, the intelligent device can always occupy the resources of the system, thereby affecting other applications. In addition, the problems of system scheduling, message queue waiting and the like exist, and the received heartbeat command can also influence the normal control command communication. Thereby affecting the experience of the user.

The following describes an exemplary method for monitoring the state of a device according to an embodiment of the present application, with a device state monitoring apparatus as a schematic execution subject. The device state monitoring apparatus may be a gateway unit, as shown in fig. 2, and further includes a monitoring device and a plurality of monitored devices, where the monitored devices include a high-voltage device and a low-power device, each low-power device is in wireless communication connection with the high-voltage device and the monitoring device, and each high-voltage device is in wireless communication connection with the monitoring device.
As an implementation manner, please refer to fig. 3 to fig. 7, in an embodiment of the device status monitoring method according to the present invention, in the method, the gateway unit and the monitoring device, and the monitoring device and the monitored device are in communication connection by using a bluetooth MESH networking. The monitoring equipment is used for replacing the gateway unit to monitor the monitored equipment. The equipment monitoring method comprises the following steps:
s101: setting one of the devices as a monitoring device, and then setting the other devices as monitored devices;
s102: the monitoring equipment acquires the state information of the monitored equipment connected with the gateway unit;
s103: within set conditions, if activity information is acquired, the state information of the monitored equipment is determined to be on-line, and if the activity information is not acquired, the state information of the monitored equipment is determined to be off-line;
s104: the monitoring equipment updates the state information of the monitored equipment in the monitoring list and the time corresponding to the state information, and sends the state information of the monitored equipment to the gateway unit.
Compared with the conventional mode of sending heartbeat data at regular time in the protocol of the Bluetooth mesh standard, the equipment state monitoring method can enable the monitoring equipment to be communicated with the gateway unit only when the state information of the monitored equipment is changed, so that the data volume of communication in the network is greatly reduced; and the state information of the monitored equipment is only sent to the monitoring equipment, and when the number of the monitored equipment is continuously increased, the communication of the control command of the gateway unit is not influenced, so that the conflict between the heartbeat data and the normal communication command is reduced.
Further, the step S101: setting one of the devices as a monitoring device, and the step of setting the other devices as the monitored devices includes:
and judging whether the equipment is strong electric equipment or not and whether the equipment meets the preset signal intensity condition or not, if so, setting the equipment as monitoring equipment, and setting the other equipment as monitored equipment.
In this embodiment, the high-voltage device refers to an electrical device having an operating voltage of 220V or higher. In the category of strong electricity, the supply and distribution projects (10KV/380V/220V) of the electric power project (more than 10 KV) belong to strong electricity. In general, a strong electric device includes: high voltage circuit breakers, high voltage cabinets, transformers, sockets, switches, lights, etc., which are normally not powered off and dormant. The signal intensity condition refers to a signal intensity condition threshold value, and the condition threshold value can be set manually, so that the purpose of screening strong electric equipment with higher signal intensity is achieved. When one device is set as a monitoring device, the other devices are set as the monitored devices and are in communication connection with the monitoring device.
Further, in step S101: and setting one device as a monitoring device, and before the step that the other devices are the monitored devices, further comprising a device power-on process. The equipment power-on process comprises the following steps:
s201: configuring and setting a multicast address, wherein the multicast address is used for receiving heartbeat data of equipment connected with a gateway unit;
s202: the equipment subscribes heartbeat data of the multicast address;
s203: and the equipment adds the equipment information connected with the gateway unit to a monitoring list of the equipment according to the heartbeat data of the multicast address.
Specifically, referring to fig. 4, fig. 4 is a power-on process of the device. In this embodiment, the status information of the device includes an online status and an offline status. All devices include strong electric devices, and low power consumption devices are powered on first, and then a network is distributed. The equipment judges whether the distribution network is successful or not by acquiring the distribution network state of the equipment, and if the distribution network is not successful, the equipment continues to wait for the distribution network; if the network distribution is successful, the equipment is powered on and then goes to a multicast address which is configured by default when the network distribution is carried out, and then a specific heartbeat data, namely a heartbeat message, is sent, wherein the heartbeat data comprises mac address information of the equipment, node addresses of the equipment, signal strength and the like. Other strong electric equipment receives the heartbeat data when subscribing the multicast address, and after receiving the heartbeat data, the other strong electric equipment adds the heartbeat data into an equipment list of the other strong electric equipment, updates the current time and simultaneously replies the heartbeat data of the other strong electric equipment to sending equipment; at this time, the two devices create corresponding device lists, that is, each of the power-on devices forms a pre-stored monitoring list. It should be noted that, since the low power consumption device may sleep and may not meet the condition of becoming a monitoring device, it may not create a list itself, and may only send heartbeat data, and may not reply heartbeat information even if it receives heartbeat data of other strong electric devices. In addition, the strong electric equipment can store the self information into the monitoring list after being powered on and before sending the self heartbeat data. In addition, as the monitoring equipment is from a certain strong electric equipment, if the strong electric equipment is judged to be the monitoring equipment, the new equipment is also identified to be powered on except for establishing the list, and at the moment, the monitoring equipment updates the monitoring list; the status information, node information, signal strength, etc. of the device are then sent to the gateway unit.
Therefore, through the electrifying process, each strong electric equipment has the condition of becoming the monitoring equipment, more connection choices are provided for the gateway unit, and the gateway unit is more beneficial to screening the strong electric equipment with the strongest signal for connection.
Further, the step S102: before the monitoring facilities obtain the state information of the monitored equipment who is connected with gateway unit, still include:
s301: the gateway unit sends a command for acquiring the state of the monitored equipment to the monitoring equipment;
s302: the monitoring equipment sends the state of the monitored equipment in the monitoring list to the gateway unit;
s303: the gateway unit compares the monitoring list of the monitoring equipment with a local equipment list;
s304: if the monitored equipment information in the monitoring list of the monitoring equipment is found to be incomplete, sending the missing monitored equipment information in the monitoring list of the monitoring equipment to the monitoring equipment;
s305: and the monitoring equipment updates the monitored equipment information in the monitoring list.
Specifically, please refer to fig. 5, in which fig. 5 is a flow of connection between the monitoring device and the gateway unit. After the gateway unit is powered on and the network is distributed, when the first heavy electric equipment is powered on, a process of connecting with the gateway unit exists. The connection process is initiated by the gateway unit, specifically, the gateway unit searches for strong electric equipment with strong signals, and actively connects after searching for proper equipment. After the connection is successful, the strong electric equipment becomes monitoring equipment; then the gateway unit sends a command for acquiring the state of the monitored equipment to the monitoring equipment; after receiving the monitoring list, the monitoring equipment sends the monitoring list to the gateway unit; the gateway unit compares the monitoring list of the monitoring equipment with a local equipment list, if the reported equipment is found to be incomplete, information of the missing equipment is sent to the monitoring equipment, if the missing equipment is strong electric equipment, the monitoring equipment inquires the latest state information of the equipment, and if the inquiry is not responded for 3 times, the missing equipment is marked to be in an off-line state; if the monitored equipment is in the online state, the monitored equipment is changed into the online state, the latest state information is updated, and after all the missing equipment is detected, the updated monitoring list is sent to the gateway unit again.
Therefore, through the connection process of the monitoring equipment, the list stored in the gateway unit and the list stored in the monitoring equipment are synchronized after the gateway unit and the monitoring equipment are connected for the first time, so that a monitoring standard in the monitoring process of the subsequent monitoring equipment is formed.
Further, the step S103: if the activity information is acquired, the state information of the monitored equipment is determined to be online, and if the activity information is not acquired, the state information of the monitored equipment is determined to be offline, in the set conditions, step S104: the monitoring device updates the state information of the monitored device in the monitoring list and the time corresponding to the state information, and sends the state information of the monitored device to the gateway unit, wherein the time comprises the following specific steps:
s401: acquiring activity information of the monitored equipment for multiple times according to preset interval time, if the activity information is acquired, determining that the state information of the monitored equipment is on-line, and if the activity information is not acquired, determining that the state information of the monitored equipment is off-line;
s402: the monitoring equipment updates the state information of the monitored equipment in the monitoring list and the time corresponding to the state information, and sends the state information of the monitored equipment to the gateway unit.
Further, the step S402: the monitoring device updates the state information of the monitored device in the monitoring list and the time corresponding to the state information, and sends the state information of the monitored device to the gateway unit, wherein the time comprises the following specific steps:
judging whether the current state information is consistent with the state information of the monitored equipment in the monitoring list of the monitoring equipment, if so, updating the state information of the monitored equipment in the monitoring list and the time corresponding to the state information by the monitoring equipment, and if not, updating the state information of the monitored equipment in the monitoring list and the time corresponding to the state information by the monitoring equipment and sending the state information of the monitored equipment to the gateway unit.
Specifically, please refer to fig. 6, in which fig. 6 is a flow of the device offline monitoring. In the monitoring process, firstly, judging whether the equipment in the monitoring list is in an online state, if so, switching to an online monitoring process; and the monitoring equipment continuously and circularly checks the monitoring interval time of each monitored equipment in the monitoring list, and if the preset interval time is met, the monitoring equipment sends a heartbeat inquiry command to the strong electric equipment. If the monitoring equipment can receive a response, the state information of the monitored equipment is determined to be on-line, then whether the state information of the monitored equipment in a monitoring list of the monitoring equipment is in an on-line state or not is judged, if yes, the time corresponding to the state information of the equipment is updated, the working state of receiving the activity message of the monitored equipment is continuously kept, the monitoring interval time of the monitoring equipment is continuously repeated, a next inquiry command is made, if not, the state information of the monitored equipment and the time corresponding to the state information in the monitoring list are updated, and the latest state of the monitored equipment is sent to a gateway unit; if the inquiry is over 3 times or no response is made, the state information of the monitored equipment is determined to be offline, then whether the state information of the monitored equipment in the monitoring list of the monitoring equipment is in an offline state or not is judged, if not, the monitoring equipment updates the state information of the monitored equipment in the monitoring list to be offline and the time corresponding to the state information, the latest state of the monitored equipment is sent to the gateway unit, and if yes, the time corresponding to the state information of the equipment is updated.
Therefore, through the device offline monitoring process, the monitoring device can actively inquire whether the heavy-current equipment is online or not, the state information of the monitored equipment is updated in time, and a user can know the use condition of the equipment in time conveniently.
Further, the device offline monitoring process further includes monitoring the low-power consumption device, and the steps are as follows:
s501: determining state information of the low-power consumption device by judging whether the monitoring device receives an activity message of the low-power consumption device within a certain time;
s502: and judging whether the state information is consistent with the state information of the low-power consumption equipment in a monitoring list prestored in the monitoring equipment, if not, updating the state information of the low-power consumption equipment in the monitoring list, sending the state information of the low-power consumption equipment to a gateway unit, and if so, updating the recording time of the low-power consumption equipment in the monitoring list.
Specifically, in the above-mentioned device offline monitoring process, the interval time between the strong electric device and the low-power-consumption device in the device state list is different, and for the low-power-consumption device, the low-power-consumption device cannot be queried because the low-power-consumption device is generally in a dormant state. In the monitoring process, as long as the interval time exceeds a preset value, the monitoring equipment does not receive a heartbeat command or other messages of the low-power consumption equipment, and determines that the equipment is in an off-line state, and at the moment, if the state information of the monitored equipment in a monitoring list of the monitoring equipment is in the off-line state, the monitored recording time in the current monitoring list is updated; if any monitored equipment is in an offline state before, the monitoring equipment suddenly receives the information of the equipment (no matter any information, as long as the MAC address of the information source or the node address is the equipment), the state information of the low-power consumption equipment in the monitoring list is updated and marked to be in an online state, and the state information is sent to the gateway unit.
Further, the step S103: if the activity information is acquired, the state information of the monitored equipment is determined to be online, and if the activity information is not acquired, the state information of the monitored equipment is determined to be offline, in the set conditions, step S104: the monitoring device updates the state information of the monitored device in the monitoring list and the time corresponding to the state information, and sends the state information of the monitored device to the gateway unit, and the method further comprises the following steps:
s601: within a preset time, if activity information is acquired, the state information of the monitored equipment is determined to be on-line, and if the activity information is not acquired, the state information of the monitored equipment is determined to be off-line;
s602: the monitoring equipment updates the state information of the monitored equipment in the monitoring list and the time corresponding to the state information, and sends the state information of the monitored equipment to the gateway unit.
Further, the step S602: the monitoring device updates the state information of the monitored device in the monitoring list and the time corresponding to the state information, and sends the state information of the monitored device to the gateway unit, wherein the time comprises the following specific steps:
judging whether the current state information is consistent with the state information of the monitored equipment in the monitoring list of the monitoring equipment, if so, updating the state information of the monitored equipment in the monitoring list and the time corresponding to the state information by the monitoring equipment, and if not, updating the state information of the monitored equipment in the monitoring list and the time corresponding to the state information by the monitoring equipment and sending the state information of the monitored equipment to the gateway unit.
Specifically, please refer to fig. 7, in which fig. 7 is a process of online monitoring of the device. In the monitoring process, the monitoring equipment receives various activity messages sent by the monitored equipment, wherein the activity messages comprise heartbeat data, beacon messages, communication information and forwarding messages, and the monitored equipment can be determined to be in an online state only by identifying the monitored equipment from which the activity messages are sent without knowing the content of the messages; subsequently, whether the activity message is from the monitored equipment in the monitoring list is judged; if not, adding the new device to the monitoring list, updating the recording time of the device, then marking the device as an online state, and sending the latest state of the device to the gateway unit; if the activity message is judged to be from the monitored equipment in the monitoring list, updating the recording time of the equipment, further judging whether the state information of the monitored equipment in the monitoring list prestored by the monitoring equipment is in an offline state, and if not, continuously maintaining the working state of receiving the activity message of the monitored equipment; if yes, the monitoring equipment updates the state information of the monitored equipment in the monitoring list to be on-line and time corresponding to the state information, and sends the state information of the monitored equipment to the gateway unit.
Preferably, in this embodiment, the monitoring list includes recording time, node address, status information, signal strength information, and battery level information of the monitored device.
Therefore, through the device online monitoring process, any new device can also access the monitoring system, and in the monitoring process, the basis for determining whether the monitored device belongs to the online state is not limited to heartbeat data, and can also be beacon messages, communication information and forwarding information, so that the efficiency of identifying the online state of the monitored device is greatly improved.
It should be noted that the device status monitoring method is not only suitable for detecting the status of the bluetooth MESH wireless network real-time device, but also suitable for detecting the status information of the wireless devices such as zigbee and WIFI, and is not limited herein.
In the device state monitoring method, the monitoring device can be communicated with the gateway unit only when the state information of the monitored device changes in the monitoring process by adopting the method, so that the data volume of communication in a network is greatly reduced, the conflict between heartbeat data and a normal communication command is reduced, the change of the device state can be quickly identified, and the communication stability of the normal command is ensured.
