Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.
In the description of the present application, the meaning of "a plurality" means two or more unless otherwise specified.
The irrigation control method provided by the embodiment of the application is applied to an irrigation control system. As shown in fig. 1, the irrigation control system 100 includes: a first control device 101, an information storage device 102 and a watering device 103.
The first control device 101 may authenticate a plurality of irrigation devices 103 and determine a one-to-one correspondence between irrigation device identifiers and irrigation devices. After the irrigation equipment certification is complete, the operating mode and equipment parameters of each irrigation equipment are determined. The first control device 101 can obtain irrigation control information configured by the user from the information storage device 102 (e.g., open valves 1, 3, 5, and 7 to irrigate the flowers at 10:00, 9, 15, 2019 with an irrigation volume of 1/2L). And sends the control information from the information storage device to the irrigation device via the first control device 101, so that the irrigation device executes corresponding actions at the preset time points according to the control information.
The information storage device 102 is configured to obtain irrigation information set by a user, and send the irrigation information to the irrigation device 103 via the first control device when the irrigation device 103 requests to obtain the irrigation information.
The watering device 103 is used to water the flowers according to the needs of the user (in the embodiment of the present application, the needs of the user are embodied as control information). The irrigation device 103 provided by the present application includes four modes of operation, which are: power saving mode, idle mode, connected mode and irrigation mode.
In the power saving mode, the terminal only performs the minimum activity to save the power.
In the idle mode, the irrigation device does not wake up, and only performs signaling interaction with the network (i.e., the first control device 101 and the information storage device 102) to obtain the irrigation information set by the user.
In the connected mode, the irrigation device 103 establishes a network bearer connection with the network at the application layer to obtain other information with a large data volume.
And in the irrigation mode, the irrigation equipment irrigates flowers and the like according to the irrigation information acquired in the idle mode.
Of the four modes, the power saving mode consumes the least amount of power, and the irrigation device 103 will be in the power saving mode most of the time. The idle mode consumes a little more power than the power saving mode, but much less power than the connected mode. Since irrigation equipment may need to frequently acquire irrigation information set by a user, the embodiment of the present application acquires irrigation information set by the user in the idle mode. The awakening times of the terminal are reduced, and meanwhile, the irrigation information set by the user is acquired with the electric quantity consumption far less than that in a connection state. The user sets the periods of entering the idle mode and the connected mode in advance, and the period of the idle mode is set to be shorter and the period of the connected mode is set to be longer.
An embodiment of the present application provides an irrigation control method, which is applied to the irrigation control system, and the following will describe in detail a technical solution of the present application by taking the first control device as a Mobility Management Entity (MME), and the information storage device as a Home Subscriber Server (HSS), where as shown in fig. 2, the irrigation control method includes S201 to S207:
s201, the irrigation equipment sends first signaling information to the first control equipment according to a preset period.
Wherein the first signaling message includes a device identifier of the irrigation device.
Specifically, the method comprises the following steps. The first signaling message is a location update message of the irrigation terminal. The information includes the current location information of the irrigation equipment, the IP address, the equipment identifier, the globally unique identifier, and the like. The irrigation device sends the location update message to the first control device after a predetermined period of time has been reached.
S202, the first control device sends the first signaling message to the information storage device.
The information storage device may be implemented as an HSS in a network.
S203, the information storage device identifies the device identifier in the first signaling message, and queries the irrigation information corresponding to the device identifier.
Specifically, the HSS receives a first signaling message sent by an MME, and identifies an equipment identifier and a global unique identifier in the first signaling message; wherein the device identifier is used to indicate which irrigation device sent the first signaling message, and the globally unique identifier is used to perform network charging for the irrigation device and routing of the signaling message. And matching according to the equipment identifier and the global unique identifier, if the corresponding equipment identifier and the global unique identifier are inquired in the HSS, the matching is successful, the irrigation equipment signs the irrigation control service, and further inquiry and judgment are carried out to judge whether the irrigation information corresponding to the equipment exists in the HSS. If the corresponding device identifier and the globally unique identifier are not queried in the HSS, the matching fails, indicating that the device is not subscribed to the irrigation control service. And returning to the irrigation control terminal to stop working or failing to update the position.
Illustratively, after a successful match, the irrigation information in the HSS is queried. The irrigation information comprises irrigation time, water valve opening and closing conditions and water valve watering amount conditions.
The above-mentioned switching water valve situation can be shown in the following table:
Figure BDA0002021966370000051
the water valve watering amount can be shown in the following table:
Figure BDA0002021966370000052
Figure BDA0002021966370000061
if the irrigation information is: time is 2019-08-05-08: 15, the Water Valve (WV) is 110, and the water per time (WQ) is 011. It means that in 2019, 8, 5, 8, 15 minutes, the water valve 6 is opened and 1/6L is watered. Wherein, a plurality of water valves and water quantity can be simultaneously arranged in the irrigation information. If the irrigation information is encoded too long, it may be divided into multiple signaling message transmissions. It will be understood by those skilled in the art that the above description of the water valve and water meter is for better understanding by those skilled in the art and is not intended to limit the number of water valves and water volumes. The irrigation device may include a plurality of water valves and may be used for irrigation in a variety of water volume settings, and one skilled in the art may adapt the codes and tables to achieve this. In an initial phase, the HSS may set the irrigation information as: time is 0, WV is 0, and WQ is 0. When the irrigation information set by the user is received, the irrigation information is converted into a corresponding code and written into the irrigation information.
Illustratively, the process of failing to match is: the irrigation terminal sends a location update message to the HSS through the MME, and the location update message carries the equipment identifier and the global unique identifier. The HSS does not inquire the corresponding equipment identification and the global unique identification, and the matching fails. At this moment, HSS records the location updating information of the irrigation terminal, and returns the location updating success message, and adds a irrigation information acquisition failure reason value in the location updating success message. And after the irrigation terminal receives the location updating success message, identifying the irrigation information acquisition failure reason value in the message. And determining that irrigation information cannot be acquired currently, and displaying to stop working.
In one implementation of this step, a user (a real user or a server subscribed by the user) may set and send irrigation information to an information storage device via short message, portal, Application (APP), Over the Air Technology (OTA), etc., and the irrigation information is stored by the information storage device (the information storage device may be implemented not only as an HSS, but also adaptively stored in other devices, such as an information temporary storage module in an MME for storing the irrigation information, or any storage device set in an appropriate location in the network. After the user sets the irrigation information, the information storage device correspondingly stores the device identifier, the global unique identifier, the location information of the user N, the subscription irrigation control service information, and the device identifier, the global unique identifier, and the location information of the irrigation device corresponding to the irrigation information.
S204, the information storage device writes the irrigation information into a second signaling message, and sends the second signaling message to the first control device.
Wherein the second signaling message may be Insertion Subscriber Data (ISD).
S205, the first control device receives a second signaling message sent by the information storage device.
Wherein the second signaling message includes irrigation information configured for the irrigation device.
In one implementation of this step, after the first control device receives the second signaling message, it is determined whether the irrigation information can be properly executed by the irrigation device. If the irrigation information cannot be properly executed by the irrigation device, sending a re-query irrigation information message to the information storage device.
Specifically, the first control device judges whether the irrigation information meets a preset condition; wherein the preset conditions include: and the water valves are completely closed but the water valve watering amount is more than 0, the water valves are opened but the water valve watering amount is 0 or the watering time is later than the current time but the water valves are completely closed and the water valve watering amount is 0. The preset conditions include, but are not limited to, the above-mentioned conditions, and any conditions that can be conceived by those skilled in the art without inventive efforts can be included in the above-mentioned preset conditions.
And if the irrigation information meets the preset conditions, determining that the irrigation information cannot be correctly executed by the irrigation equipment. The first control device sends a re-query irrigation information message to the information storage device. So that the information storage device returns a new second signaling message again and continues to make the determination.
In one implementation of this step, to avoid the first control device continuing to send re-query irrigation information messages to the information storage device, the number of times the messages are re-queried is set to 3. Over 3 times there will be no re-queries.
And S206, the first control equipment sends the second signaling message to the irrigation equipment.
S207, the irrigation equipment receives second signaling information sent by the first control equipment and irrigates according to the irrigation information in the second signaling information.
According to the irrigation control method provided by the embodiment of the application, irrigation equipment sends first signaling information to first control equipment according to a preset period; so that the first control device acquires a second signaling message from the information storage device; wherein the first signaling message includes a device identifier of the irrigation device; the second signaling message comprises irrigation information set for the irrigation equipment; the irrigation equipment receives second signaling information sent by the first control equipment; and the irrigation equipment irrigates according to the irrigation information in the second signaling information. The irrigation equipment can acquire the irrigation information set by the user from the first control equipment through the position updating message, the network returns the irrigation information through the signaling message, and the irrigation equipment does not need to establish bearing connection with the network in the whole process, so that the power consumption of the irrigation equipment is greatly reduced, and the operation time of the irrigation equipment is improved.
In one implementation of the embodiment of the present application, before the step S201, the irrigation terminal may also register in the network first. The registration process comprises the following two registration modes:
the first method is as follows: the irrigation control system further comprises: a wireless access device; the wireless access device is pre-stored with a device identifier of the first control device. The method specifically comprises the following steps: the irrigation equipment sends third signaling information to the wireless access equipment; the wireless access equipment sends the third signaling to any control equipment in a control equipment set; wherein the control device set comprises at least one first control device and at least one second control device; the first control device is a control device capable of controlling the irrigation device; the control equipment sends the third signaling message to the first control equipment according to a preset rule; the first control equipment authenticates the irrigation equipment according to the third signaling message; and if the first control equipment successfully authenticates the irrigation equipment, storing the equipment information of the irrigation equipment in the first control equipment.
Wherein the sending, by the control device, the third signaling message to the first control device according to a preset rule includes: the control device set comprises n control devices, wherein a first control devices, b second control devices and a total control device; n is a + b + 1. The general control equipment is pre-stored with an equipment list of the first control equipment, the wireless access equipment sends the third signaling message to the general control equipment, the general control equipment inquires the first control equipment which is currently in accordance with the equipment list of the first equipment and controls the irrigation equipment, and sends the third signaling message to the first control equipment.
Or the control equipment set comprises n control equipment in total, and the n control equipment are networked in a group pool mode; c first control devices and d second control devices; n is c + d. And the wireless access equipment sends the third signaling message to any one of the n control equipment, and if the control equipment is not the first control equipment, the wireless access equipment sends the third signaling message to the next control equipment which is linked with the control equipment, and the third signaling message is sent to the first control equipment in sequence until the third signaling message is sent to the first control equipment, and the control equipment controls the irrigation equipment.
The second method comprises the following steps: the irrigation control system further comprises: a wireless access device; the wireless access device is pre-stored with a device identifier of the first control device. The method specifically comprises the following steps:
the irrigation device sends a third signaling message to the wireless access device. To cause the wireless access device to send the third signaling message to the first control device; and the first control equipment authenticates the irrigation equipment according to the third signaling message. And if the first control equipment successfully authenticates the irrigation equipment, storing the equipment information of the irrigation equipment in the first control equipment.
Exemplarily, the third signaling message is an attach message, and the control device is an MME, which is taken as an example to describe in detail:
when the irrigation device is operated or restarted for the first time, after logging in the network for the first time, the irrigation device sends an attach message to the network, and adds a control panel instruction parameter of 1 to the attach message (the control panel instruction parameter of 1 is only an exemplary illustration, and other implementation manners may be possible in specific implementation cases). And adding the device to support the parameter information such as the networking device.
Since the internet of things is different from the MME of the network currently provided by the operator for the user, after receiving the attach message, the radio access device needs to query the MME supporting the internet of things, and the MME controls the irrigation device. The wireless access device queries the MME supporting the internet by the method provided in the first or second manner. And the MME authenticates and authenticates the irrigation equipment according to the attachment message. The message of the irrigation device is stored in a temporary information storage unit in the MME after the authentication is passed. The irrigation equipment is registered.
If not, the radio access equipment sends an attach reject message to the irrigation equipment, and carries a control plane command parameter of 0 or a special cause value # 78. And enabling the irrigation equipment to resend the attachment message and attempt to register in the MME corresponding to the other wireless access equipment.
In another implementation manner of the embodiment of the present application, there is also provided a location updating method after a location of a watering terminal is changed, including: if the position of the irrigation equipment changes, the irrigation equipment sends a fourth signaling message to a third control equipment; so that the third control equipment acquires the equipment information of the irrigation equipment and irrigation information corresponding to the irrigation equipment from the first control equipment; wherein the third control means is control means for controlling the irrigation means after a change in position of the irrigation means.
For example, taking that the first control device and the third control device are both an MME supporting an internet of things function, and the fourth signaling message is a location update message as an example, the method specifically includes:
before this step, the irrigation terminal has already completed registration in the MME of the network, and the registered MME retains the device information of the irrigation device and the corresponding service information (including device identifier, globally unique identifier, authentication information subscription service of the device, and irrigation information obtained through the HSS). When a change in location of the irrigation device occurs, the original MME may be far from the irrigation device and may not be able to control the irrigation device. In this case, an MME needs to be searched again for the irrigation device in the area after the location change to control the irrigation device.
The irrigation device sends the location update message to the wireless access device again in the idle state period after the location change and triggers the location update. The location update message also adds a control panel command parameter equal to 1, adds the terminal identity of the original MME when the terminal is registered in the MME.
The wireless access device determines that the location of the terminal has changed at this time, and needs to search for a new MME for controlling the irrigation device, and then queries the new MME according to the first or second method of the previous embodiment, and sends the location update message to the new MME. After receiving the location update message, the new MME acquires, from the source MME, the device information of the irrigation device and corresponding service information (including the device identifier, the globally unique indication, the authentication information subscription service of the device, and the irrigation information acquired by the HSS) according to the terminal identifier of the original MME during registration in the location update message. The device information of the new MME irrigation device and the corresponding service information are stored in its own temporary information storage device. And after the position of the irrigation equipment is updated successfully, the irrigation information signaling message is sent to the irrigation equipment. And leading the irrigation equipment to irrigate according to the irrigation information.
In this implementation, the HSS may periodically send the irrigation information to the MME, so that the MME stores the irrigation information in its temporary information storage device, thereby avoiding an untimely update of the irrigation information. After the irrigation equipment changes and the new MME is updated, the new MME obtains its stored irrigation information from the old MME. However, the irrigation information stored in the original MME is not the latest information set by the user due to the fact that the position of the irrigation device in the original MME is not updated in time, the HSS updates the irrigation information in the original MME in time, or other reasons.
Therefore, before the new MME obtains the signaling message, two reference periods are set, one period is set for the HSS to send the irrigation information to the MME and the irrigation device to transmit the user information data, for example: the period for HSS to send irrigation information to MME is 50min, and the period for irrigation equipment to send location update information is 30 min. And storing the two periods in a new MME, and when the new MME judges that the pouring information is more than 50min from the last time of sending the pouring information by the HSS and the position of the pouring equipment is not updated in the original MME for more than 30min, judging that the pouring information in the original MME is probably not the latest pouring information, and sending the data query message to the HSS by the new MME so that the HSS sends the latest pouring information to the new MME.
The old MME determines that the irrigation device has not been location updated for more than 30min, and considers it to complete location update in the new MME, and deletes all information about the irrigation device. Alternatively, the old MME determines that the irrigation device has not been updated for more than 30min, and then keeps the irrigation device information for a while, and deletes all information about the irrigation device after a while.
And the new MME judges that the irrigation equipment has not been subjected to position updating for more than 30min, continuously waits for 50min (the period of sending new irrigation information by HSS), and sends a request for acquiring irrigation information to HSS or directly returns abnormal information of position updating of the irrigation equipment.
And when the new MME judges that the position of the irrigation equipment is updated normally, but the HSS does not send irrigation information according to the 50min period, actively sending a request for acquiring the irrigation information to the HSS. Irrigation information is updated.
In the embodiment of the present application, the irrigation control device may be divided into functional modules or functional units according to the above method examples, for example, each functional module or functional unit may be divided for each function, or two or more functions may be integrated into one processing module.
