Description
Technical Field
The invention belongs to the technical field of agricultural irrigation, and particularly relates to a dual-core ultra-low power consumption irrigation control device based on a Cat1 network.
Background
With the rapid development of agriculture in China, the agricultural planting area is continuously enlarged and scaled, and an automatic irrigation system is produced at the same time. The traditional irrigation mode is developed to automatic irrigation, so that the utilization rate of water resources can be improved, the yield of crops can be increased, and the production cost is reduced.
In the prior art, an automatic irrigation system usually needs to be paved with a plurality of cables, and the wiring engineering is troublesome in northwest regions due to topography; the solar lithium battery power supply system without wiring is poor in low temperature resistance of the lithium battery, and the solar panel is easily shielded by a sand layer in the application environment, so that the stability is influenced and the implementation is difficult. Meanwhile, although the irrigation system is in a dormant state for a long time, the actual power consumption is much larger than that in imagination because the system is not powered off. In addition, the controller in the traditional mode only has one single chip microcomputer, and the possibility of failure is high when the processing task is complex, so that the single chip microcomputer cannot sleep, and the electric quantity of the battery is exhausted quickly.
Disclosure of Invention
In view of the above defects of the prior art, the present invention aims to provide a dual-core ultra-low power consumption irrigation control device based on a Cat1 network, wherein the device is based on a Cat1 network, which has the advantages of low power consumption, low cost and strong data transmission stability; in addition, the dual-core design enables the whole power consumption of the device to be extremely low, the service life to be long, the stability to be enhanced, and the disposable low-temperature-resistant lithium sub-battery can be used in extremely cold and extremely hot areas, so that the device is wide in application region, low in use cost and high in stability.
In order to achieve the above objects, in one aspect, the present invention provides a dual-core ultra-low power irrigation control device based on a Cat1 network, the device comprising a power module, a main function control module, a low power control module, a Cat1 network module and a solenoid valve control circuit module; wherein,
the output end of the power supply module is connected with the low-power consumption control module;
the low-power consumption control module is connected with the main function control module and manages all power switches of the device;
the main function control module is connected with the Cat1 network module and the electromagnetic valve control circuit module;
the Cat1 network module is used as a communication module to be connected with the server for communication;
the electromagnetic valve control circuit module controls the opening and closing of the electromagnetic valve.
Furthermore, the power module comprises a disposable low-temperature-resistant lithium sub-battery, the battery capacity of the disposable low-temperature-resistant lithium sub-battery is 19000mAh, the nominal voltage is 3.7V, the bearable temperature range is-60 ℃ to +85 ℃, the disposable low-temperature-resistant lithium sub-battery is used for supplying power to the whole set of device and can be used in extremely cold and extremely hot areas.
Further, the low-power consumption control module adopts a single chip microcomputer of Stm32L011F4P6 model, and is used for managing all power switches of the device. Specifically, when a server needs to be connected to update an irrigation task, the low-power-consumption control module turns on power switches of the main function control module and the Cat1 network module; after the task is finished, all power switches are turned off, and the power switches enter a dormant state.
Further, the low-power-consumption control module can check the voltage of the disposable low-temperature-resistant lithium sub-battery, and if the voltage of the disposable low-temperature-resistant lithium sub-battery is detected to be lower than a threshold value, the low-power-consumption control module sends a low-voltage warning to the server through the main function control module and accumulates the number of times of the low-voltage warning; when the number of low voltage warnings exceeds a certain number (e.g., 10), the low power control module will turn off all power and sleep for a period of time (e.g., 4 hours).
Furthermore, the main function control module adopts a processor of imx6ull model, and the function of the main function control module is responsible for interacting with the server, updating the irrigation task, calculating the time for starting operation next time, and sending the time to the low-power consumption control module through a serial port; and after receiving the signal, the low-power-consumption control module sets the sleep time, closes all power switches and enters the sleep mode.
Further, the Cat1 network module adopts EC200S wireless communication module or similar low power consumption cellular network communication module, when the main function control module needs to connect to the server, PPP dialing is completed through the Cat1 network module, thereby completing the connection with the server. The EC200S wireless communication module is a 4G module, and the transmission rate of the wireless communication module is lower than that of the standard 4G module, but the wireless communication module can also reach 5Mbps at the uplink and 10Mbps at the downlink. For the internet of things equipment with low data volume, the bandwidth is enough. The power consumption is low, the operation power consumption is as low as about 40mA under the condition of 3.3V voltage through actual measurement, and the power consumption can well support the device to operate for about 4 years.
Further, in terms of circuit design, a voltage boost circuit is arranged between the power switch of the Cat1 network module and the Cat1 network module, and the voltage boost circuit is used for boosting the voltage provided by the power module.
Furthermore, the electromagnetic valve control circuit module is used for controlling the on-off of the electromagnetic valve so as to complete the timed irrigation task.
Further, the power module further comprises a super capacitor, and the super capacitor is used for providing a transient large current when the Cat1 network module is dialed so as to ensure that the power supply voltage of the whole set of device is normal at the moment of dialing.
Furthermore, the hardware of the main function control module is connected with an external real-time clock module, and when the main function control module synchronizes tasks from the server, the server can synchronize the time of the main function control module so as to ensure the accuracy of the time of the main function control module.
The operation flow of the low-power consumption control module is as shown in fig. 2, after the low-power consumption control module is powered on, all power supplies (power supplies of the main function control module and the Cat1 network module) are turned on and a timer for 3 minutes is started at the same time, as the time for the main function control module to complete updating and executing of tasks under normal conditions is within 3 minutes, if the time is out, an abnormal condition is indicated, and in order to save power consumption, if a sleep command sent by the main function control module is not received within 3 minutes, the low-power consumption control module turns off all power supplies, stores configuration, forcibly sleeps for 4 hours, and waits for next synchronization or task execution;
after the low-power consumption control module turns on all power supplies, reading the configuration of the power supply module, and detecting the voltage of the disposable low-temperature resistant lithium-ion battery; when the battery voltage is detected to be low voltage for 10 times continuously, the low power consumption control module turns off all power supplies to enter the sleep mode. The low power consumption control module has 10 opportunities to send a low voltage alarm to the server to prompt the user to change the battery. If the detection voltage is normal, the low-power consumption control module can monitor the command of the main function control module all the time. When a reading command is monitored, the low-power-consumption control module sends local configuration parameters to the main function control module; when a sleep command is monitored, the low-power-consumption control module sets sleep time according to the time parameter of the main function control module and closes all power supplies before sleep.
The operation flow of the main function control module is as shown in fig. 3, when the main function control module is powered on, the main function control module will first start the PPP dialing program and always try to connect with the server. After the server is successfully connected with the server, the main function control module sends a heartbeat packet to the server, the heartbeat packet comprises a task ID of the current device, the server receives the heartbeat packet and then compares the task ID in the heartbeat packet with the latest task ID, if the task ID in the heartbeat packet is different from the latest task ID in the heartbeat packet, the server sends the latest task to the main function control module, and otherwise, a task-free updating task is sent; when the connection between the main function control module and the server is overtime, the main function control module judges that the current network is abnormal and stops the attempted connection with the server. Whether the connection with the server is successful or not, the main function control module operates the local time task once to control the current state of the valve, calculates how long the main function control module needs to be awakened according to the time task, sends the calculated awakening time to the low-power-consumption control module, and after receiving the command, the low-power-consumption control module closes all power supplies, sets the dormancy time and then sleeps to wait for the next awakening. Therefore, the mechanism of double-database confirmation of the main function control module and the server can ensure that the task can be updated when the server is connected next time even if the network fails.
The main function control module is in a power-off state for a long time, and when the main function control module runs, a valve is switched on or switched off or a connection server checks whether a new task is updated or not during a main task. After the main function control module is connected with the server to synchronize tasks, the tasks are locally performed in the main function control module and are irrelevant to the server, namely, the tasks are operated by adopting offline tasks, and the stability of task operation is ensured. When the main function control module runs a task, the time of action required by each valve at the next time and the time of updating the task by connecting a server at the next time are calculated, the time closest to the current time is selected from the times to be used as the time of starting at the next time after the main function control module is in dormancy, the dormancy duration is calculated, and the dormancy duration is transmitted to the low-power-consumption control module to enter a dormancy state.
The user can modify the frequency that the device updated the task through the task, when needing water in the busy season, can improve the frequency that the device connects the server like this, ensures the promptness that the task was updated, and when needing water in the off season, the plant does not need too much irrigation, can reduce the frequency that the device connects the server, reduces the consumption that needs water in the off season device, prolongs the life-span of battery.
The hardware design frame diagram of the device is shown in fig. 4, a disposable low-temperature-resistant lithium-ion battery in a battery module supplies power to the whole device, and the super capacitor is used for supplying instantaneous large current of about 2A when the Cat1 network module dials, so that the power supply voltage of the whole system is normal at the dialing moment. Preferably, in order to further save the electric quantity of the disposable low-temperature-resistant lithium-ion battery in the device, a micro water flow turbine generator can be connected to the outside of the device, is installed at the outlet of any valve and is connected with a super capacitor in the device, so that the energy of water flow can be utilized to charge the super capacitor during irrigation every time, and the purpose of further reducing the internal power consumption of the device is achieved.
In circuit design, the low-power consumption control module manages power switches of the Cat1 network module and the main function control module, and because the working power supply required by the Cat1 network module is 4V, and the nominal voltage provided by the disposable low-temperature-resistant lithium-ion battery is less than 4V, a booster circuit is arranged between the power switch of the Cat1 network module and the Cat1 network module, and the normal work of the Cat1 network module is ensured after voltage boosting.
The beneficial technical effects of the invention are at least shown in the following aspects:
1. because the irrigation system has low requirements on the network aging and the network speed, the invention adopts the Cat1 network, so that the network coverage cost and the hardware cost are both lower, the power consumption is low, and the coverage is wide.
2. The invention innovatively adopts a dual-core mode of adding a singlechip with extremely low power consumption (a low power consumption control module) and a singlechip with a main function (a main function control module), realizes the ultralow power consumption of the device during dormancy, and realizes the remote modification of the irrigation plan by an off-line task upgrading mode. The low-power consumption control module has simple logic, ensures the stability of entering a dormant state, has only the power consumption of the low-power consumption control module in the dormant state compared with a device with only one main function control module, greatly reduces the overall power consumption of the device, prolongs the overall service life and saves the use cost; the main function control module can not consider the power consumption in the dormancy process, has higher main frequency, and greatly reduces the time for processing tasks each time.
3. The disposable low-temperature-resistant lithium-ion battery is adopted, so that the whole set of device has wide application scenes and can be used in extremely cold and hot areas.
4. The low-power-consumption control module can monitor the service condition of the battery, and can timely send a notice to remind a user when the electric quantity of the battery is exhausted, so that the electric quantity condition of the battery is transparent, and the condition that the use of the device is delayed due to the exhaustion of the battery is prevented.
