Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Most of the automatic control modes on the market at present are designed based on the condition that a communication link is normal. In the case of an unstable or offline communication link, such automation actions are often handled directly as failure results, and even if the communication link is restored to normal, the automation that the person wants to perform with consciousness or will not be handled immediately. The consciousness and the will of people can not be implemented in the real controlled object.
As shown in fig. 1, the water sensor detects a water immersion event and reports the water immersion event to the server, and the server notifies the alarm device to alarm through the stored automation rule (if the water immersion condition is met, the alarm device is notified to alarm), but once the network connection is abnormal, the action cannot be executed. Even if the network communication returns to normal after a period of time, an alarm will not be triggered because the flooding event occurred previously. Namely, after the network communication is recovered to be normal, the alarm device still cannot be used for giving an alarm when the water sensor detects a water immersion event.
In order to optimize the problem that the notification control cannot be performed due to network abnormality as shown in fig. 1, the inventor adds a retransmission mechanism for optimization, i.e. retransmission at regular intervals, and can issue a control command to the alarm device when the network returns to normal. However, under the condition of periodic retransmission, other requirements for automation control cannot be met. Referring to fig. 2, as shown in fig. 2, the door lock reports the door opening event at point 21, and the server turns on the light according to the automation rule (if the door opening event report is satisfied, the light is turned on). If the 21-point network connection is abnormal and the lamp cannot be turned on, the server periodically retransmits the lamp, and the network returns to the normal condition after people have a rest at 23 points, and the lamp is turned on because of the system retransmission mechanism, and the action of turning on the lamp is not expected by people.
In order to overcome the above problems, an apparatus control method is provided in an embodiment of the present application and applied to a server, please refer to fig. 3, where fig. 3 is a flowchart illustrating the apparatus control method provided in the embodiment of the present application. As shown in fig. 3, the device control method includes:
s103, judging whether the expected state is the same as the current state of the shadow device. If yes, go to S112; if not, S104 is executed.
Specifically, if the expected state is the same as the current state of the shadow device, the control instruction does not need to be issued to the real device, and then S112 is executed; otherwise, S104 is executed.
Wherein the shadow device is a copy created in the server (platform) corresponding to the real device. Each shadow device corresponds to a different real device. The shadow device is used for caching and displaying the current state of the corresponding real device. The real device is a controlled device which receives the server regulation instruction, such as an alarm and a lamp in the above example.
And S104, generating a control command according to the expected state.
Specifically, the control instruction is used for controlling the corresponding real device to switch to a desired state. For example, the real device corresponding to the shadow device is a lamp, the current state of the shadow device is an off state, and the desired state is an on state, and at this time, a control instruction needs to be generated according to the desired state. The method aims to enable the real device to be switched to the open state through the control instruction, so that the current state of the shadow device is switched to the open state and is consistent with the expected state.
S105, judging whether the real device corresponding to the shadow device is in a communicable state. If yes, executing S106; if not, S107 is executed.
Specifically, if the real device is in a communicable state, the control instruction is directly issued to the real device, so that the real device is switched to an expected state, and S106 is executed; on the contrary, if the corresponding real device is not in a communicable state, it is necessary to determine whether the type of the control command is the first type, and then S111 is executed.
And S106, sending the control command to the real equipment.
Specifically, the real device switches to the desired state after receiving the control instruction. For example, the real device is the lamp, and after the lamp receives the control instruction, the lamp quickly responds to the control instruction and is switched to the on state, so that the lighting requirement of the user is met.
And S111, sending the control command to the real equipment under the condition that the real equipment is recovered to a communicable state.
Please refer to the above example, the real device is an alarm device. When the water sensor detects a water immersion event, the real device is in a non-communicable state, and at this time, the user cannot be notified that the water immersion event occurs. Under the condition that the network is recovered to be normal, the real equipment is recovered to be in a communicable state, and the control command is issued to the alarm device again, so that the user is informed that the flooding event happens once when the real equipment is in a non-communicable state, and the situation that the flooding event is informed and potential safety hazards are generated is avoided.
And S112, ending.
In another optional implementation, the control instruction carries a timestamp indicating a generation time, and if a real device corresponding to the shadow device is in a communicable state, the method further includes:
judging whether the type of the control instruction is a first type;
if so, judging whether the interval between the timestamp and the current time exceeds a preset time threshold, wherein the first type of control instruction has timeliness;
if the control command exceeds the preset control command, confirming that the control command is invalid;
and if not, issuing the control command to the real equipment.
In the embodiment, the real device corresponding to the shadow device is confirmed to be in a communicable state, then the type of the control instruction is judged, when the control instruction is time-efficient, whether the interval between the timestamp when the control instruction is generated and the current time exceeds a preset time threshold value is judged, if so, the control instruction is considered to be invalid, and the control instruction is not issued to the real device. And if not, directly sending the control command to the real equipment.
On the basis of fig. 3, in order to avoid the problem that the real device executes an expired control instruction and generates interference to the user when the real device is the lamp in the above example, an embodiment of the present application further provides a possible implementation manner, please refer to fig. 4, where the device control method further includes:
s107, judging whether the type of the control command is a first type or a second type. If the type is the first type, executing S108; if the second type is determined, S110 is executed.
Specifically, if the type of the control instruction is not the first type, it indicates that the type of the control instruction is the second type, and S110 is executed.
Wherein the first type of control instruction is time-sensitive and the second type of control instruction is continuously valid.
Specifically, as shown in FIG. 2, the lamp is a real device (the type of the control command corresponding to the lamp is a first type; as shown in FIG. 1, the alarm device is a real device, and the type of the control command corresponding to the alarm device is a second type).
And S108, judging whether the interval between the timestamp and the current time exceeds a preset time threshold value. If yes, executing S109; if not, S111 is executed.
Wherein the control instruction carries a timestamp representing the time of generation. Under the condition that the expected state is different from the current state of the shadow device, the server needs to generate a control instruction, and the timestamp is the generation time of the control instruction. The timestamp is used for judging whether the control instruction of the shadow device is effective or not under the condition that the control instruction is of the first type.
Specifically, as shown in fig. 2, the real device (lamp) is a transient device, and the type of the control command corresponding to the lamp is a first type. When the door lock reports a door opening event at point 21, when the door lock is opened, a user can open the lamp conveniently, the generated expected state is an open state, and the current state of the shadow device corresponding to the lamp is a closed state, so that a control instruction for opening the lamp is generated, and a timestamp carried by the control instruction is, for example, 21: 00(21 point 0 point). However, at this time, the lamp is not in a communicable state, and the control command cannot be issued to the lamp.
In order to avoid that the user has a rest at the 23 th point and the communication network of the lamp recovers to the normal condition, the server issues a control instruction to the lamp at the 23 rd point, and the lamp is turned on due to the system retransmission mechanism, so that the rest of the user is influenced, and unnecessary waste is caused. And judging whether the interval between the timestamp and the current time exceeds a preset time threshold value. If yes, confirming that the control instruction is invalid, optionally deleting the control instruction, and executing S109; if not, the control instruction is still valid, and when the real device is restored to a communicable state, the control instruction is issued to the real device so that the real device is switched to an expected state, and S111 is executed.
Please continue to refer to the above example, suppose that a door opening event is reported when the door lock is in 21: 00/second, and under the condition that other conditions are not changed, if the lamp is restored to a communicable state in 21: 00/01/second, at this time, the interval between the timestamp and the current time is smaller than a preset time threshold, at this time, the lamp is turned on, which is helpful for the user to observe the environment, at this time, a control instruction is issued to the real device (lamp) so as to switch the real device to an expected state, that is, the lamp is switched to an open state.
And S109, confirming the control command failure.
Specifically, in the case where the control instruction fails, the control instruction is not issued to the real device any more even in the case where the real device is restored to the communicable state.
S110, keeping the control command continuously effective.
Specifically, the control instruction is kept valid all the time, and in the case where the real device is restored to a communicable state, S111 is executed to issue the control instruction to the real device, so that the real device is switched to a desired state. For example, the alarm device shown in fig. 1 is a real device, the type of the control instruction corresponding to the alarm device is a second type, and when the alarm device is restored to a communicable state, even if a water sensor which has occurred before detects a water immersion event, the server issues the control instruction to the alarm device, so that an alarm is triggered, and the alarm event is prevented from being missed.
On the basis of fig. 3, regarding how to determine the current state of the shadow device, a possible implementation manner is further provided in the embodiment of the present application, please refer to fig. 5, where the device control method further includes:
and S101, updating the current state of the shadow device according to the current state uploaded by the real device.
Specifically, the real device uploads the current state of the real device at a fixed frequency, and the server updates the current state uploaded by the real device to the current state of the shadow device after receiving the current state uploaded by the real device.
Alternatively, due to network instability, the communication state of real devices changes frequently, and the devices are frequently brought up and down. When a client sends a request for acquiring the current state of the real device, the real device is disconnected and is not in a communicable state, and the server cannot acquire the current state of the real device and cannot feed back the current state of the real device to the client in time. In the embodiment of the application, because the current state of the shadow device is updated according to the current state uploaded by the real device, the current state of the shadow device can be issued to the client when the client transmits the acquisition request, so as to meet the requirements of the client.
Optionally, in the prior art, when the server simultaneously obtains the obtaining requests of the current states of multiple same real devices, the server needs to obtain the current states of the real devices multiple times, and even if the response results are the same, the real devices need to respond multiple times according to the requests. However, the real device has limited processing capability, and cannot concurrently process multiple requests, thereby affecting the operation of the real device. In the scheme provided by the embodiment of the application, the current state of the shadow device is only required to be used as a result to feed back different demanders, and the operation of the real device cannot be influenced.
On the basis of fig. 3, regarding how to generate the desired state, the embodiment of the present application further provides a possible implementation manner, please refer to fig. 6, where the apparatus control method further includes:
and S102, generating an expected state according to the state change information transmitted by the associated equipment or the demand instruction transmitted by the client.
The associated equipment is equipment in linkage relation with the real equipment, and the client is a terminal for managing the real equipment.
Specifically, with continuing reference to fig. 1 and 2, in the case where the real device is an alarm device, the water sensor is associated with the alarm device, and in the case where the real device is a light, the door lock is associated with the light. The client is a terminal with real equipment management authority, and can be a mobile phone terminal, a computer terminal or other intelligent terminals.
Optionally, on the basis of fig. 3, regarding how to implement device control, a possible implementation manner is also provided in the embodiments of the present application, please refer to fig. 7, where the device control method includes S101 to S112.
Optionally, the current state of the shadow device in the embodiment of the present application is persistently stored in a database.
To sum up, the device control method provided by the embodiment of the present application is applied to a server.
