Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only partial embodiments of the present application, but not all embodiments. 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 application.
It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In accordance with an embodiment of the present application, there is provided a method embodiment of a soil sensor burglar alarm method, it being noted that the steps illustrated in the flowchart of the drawings may be carried out in a computer system such as a set of computer executable instructions and that, although a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be carried out in an order different than that presented herein.
Fig. 1 is a schematic view of a soil temperature and humidity sensor according to the related art, in fig. 1, 1 is a housing, and 2 is a temperature and humidity detecting head. The surrounding soil environment is detected through the detection head, and the obtained data is stored in the internal memory or uploaded to the server. As can be seen from fig. 1, the soil sensor is a sensing device with a small volume inserted into soil, and therefore, the soil sensor is easily stolen by a lawbreaker, which causes a loss to a user.
Fig. 2 is a burglar alarm method of a soil sensor according to an embodiment of the present application, as shown in fig. 2 and 3, the method including the steps of:
step S202, obtaining a vibration amplitude value of the soil sensor.
Optionally, a vibration amplitude value of the soil sensor is received by the vibration sensor, which may be determined by: when the number of the vibration sensors is one, acquiring a vibration amplitude value of a single vibration sensor, and taking the vibration amplitude value of the single vibration sensor as the acquired vibration amplitude value of the soil sensor; when the number of the vibration sensors is multiple, obtaining vibration amplitude values collected by each vibration sensor of the multiple vibration sensors at the same moment to obtain multiple vibration amplitude values; and determining an average value of the vibration amplitude values, and taking the average value as the acquired vibration amplitude value of the soil sensor.
In particular, one or more vibration sensors may be provided on the housing portion of the soil sensor to obtain data on the vibration amplitude and the number of vibrations of the soil sensor. The vibration sensor can be a VT17772304-20mA vibration transmitter, and when the vibration transmitter works, the vibration sensor can collect and transmit the vibration received by the soil sensor shell and caused by external force to the main control unit. The master control unit may be an integrated chip processor such as an ARM9, a single chip, etc.
It should be noted that, when a vibration sensor is arranged in the soil sensor housing, the vibration sensor can be arranged on the position of the axial lead of the soil sensor housing (near the center of gravity), so that when the soil sensor receives vibration, the vibration data received by the vibration sensor is uniform and accurate due to the fact that the propagation time of the vibration frequency is basically the same and the vibration attenuation is close. When setting up a plurality of vibration sensor in the soil sensor shell, can with vibration sensor evenly distributed inside the soil sensor shell to read a plurality of vibration sensor's average value through the main control unit.
Through the embodiment, the effect of accurately measuring the vibration data can be achieved, and misjudgment on the theft information is reduced.
And step S204, judging whether the vibration amplitude value of the soil sensor meets a first condition.
Specifically, a first condition may be set for the vibration amplitude value, and the first condition may be a threshold value to determine whether the amplitude value satisfies the threshold value. For example, the threshold may be an amplitude of 1cm, and when the vibration sensor detects that the vibration amplitude of the soil sensor is greater than or equal to 1cm, a vibration amplitude signal is output to the main control unit.
It should be noted that, as shown in fig. 5, when the main control unit receives a vibration amplitude signal exceeding a threshold, the main control unit sends an awakening signal to the main control unit of the soil sensor, and when the main control unit is currently in a dormant state during sending, the main control unit is awakened by using the awakening signal, and then the main control unit receives the vibration amplitude value; and when the main control unit is in a working state during transmission, the vibration amplitude value is received by using the main control unit. By switching the working mode 50 in fig. 5 and the sleep mode 52 in fig. 5, the purpose of reducing the energy consumption of the soil sensor can be achieved, and for the current battery endurance of the soil sensor, the energy consumption of the sleep mode and the working mode is about a hundred times different.
Step S206, when the first condition is met, acquiring an environment state value of the environment where the soil sensor is located, wherein the environment state value is used for quantifying the environment state of the environment where the soil sensor is located.
According to the above-described embodiment, the first condition may be that when the vibration amplitude value of the vibration sensor is greater than or equal to a set threshold value, which may be 1cm, then acquiring the environmental state value of the environment in which the soil sensor is located is performed,
specifically, the environmental status is usually determined by various factors, and the environmental status is generally an unquantized distribution parameter, and based on the above problem, the embodiment extracts the environmental status value for the parameter associated with the soil sensor theft prevention to further quantify, for example, the moisture data is taken as a quantification parameter alone, and the calculation is performed in the manner of soil moisture content percentage. By quantifying the environmental parameters, the calculation of the embodiment is more convenient and scientific.
Optionally, the step of acquiring an environmental state value of an environment in which the soil sensor is located includes at least one of: acquiring the times that the reading of the vibration sensor in a first time period is greater than a first threshold value, and taking the times as the environmental state value; acquiring moisture data of the environment collected by the soil sensor, and taking the moisture data as the environment state value; and acquiring the current detection time of the soil sensor and the position change information of the last detection time of the current detection time.
Specifically, acquiring the number of vibrations of the vibration sensor requires counting the number of times collectively over a period of time. For example, a value of the number of vibrations per 600 seconds may be set to a, and when the value of a is greater than 5 (a first threshold value), the number of vibrations is taken as the environmental state value. Moisture data's acquisition can utilize the humidity in the soil sensor to detect the head, can adopt chemical humidity to detect head or physical expansion coefficient humidity to detect the head etc. for example, detect the head and can set up one or more, when detecting the head and set up to a plurality ofly, as the optimal selection, detect the head through the casing setting and detect position linkage point, its evenly distributed is on soil sensor shell to reach the purpose of most accurate test moisture data. The detection of the position change information can be realized by utilizing a GPS positioning device to acquire GPS positioning data and transmitting the GPS positioning data to a main control unit for processing, and a storage element of the main control unit sequences the GPS position information in a time marking mode and compares the position information of N and N-1 according to a queue data structure mode to obtain the change distance value of the final GPS position information.
Step S208, judging whether the environment state value meets a second condition, and determining whether to alarm according to the judgment result.
Specifically, the first condition may be that a parameter obtained by quantizing the environmental state value is compared with a preset threshold, wherein the parameter may be moisture data, GPS data, and vibration frequency data of the vibration sensor. Synthesize the judgement of above factor to environmental state change, in addition, moisture data among the environmental state value is not restricted to soil moisture, can also be soil conductivity, salinity, PH, nitrogen phosphorus potassium content etc. and the sensor quantity of gathering moisture data simultaneously also can be a plurality of, and the collection degree of depth also can be different. The reliability of threshold value detection can be improved through the mode, and the information whether the soil sensor is stolen can be accurately obtained.
Optionally, when the number of times is greater than a corresponding second threshold, generating a first alarm signal, and determining to alarm; when the moisture data is smaller than a third threshold value, generating a second alarm signal and determining to alarm; and when the distance between the position of the soil sensor at the current detection moment and the position of the soil sensor at the last detection moment is greater than a corresponding fourth threshold value, generating a third alarm signal and determining to alarm.
Specifically, the moisture data may be a percentage value of soil moisture acquired by the moisture detection device, and the third threshold may be an average threshold of one or more thresholds. When the third threshold is a threshold, the threshold may be 0%, that is, when the moisture detection device detects that the moisture in the soil is 0%, it may be determined that the soil sensor may have been taken out of the soil by the thief, and thus the moisture detection device may not detect the moisture value in the soil. In another case, when the third threshold is an average threshold of the multiple thresholds, the multiple thresholds may be a sum of all instant moisture data of the target soil sensor and all instant moisture data of other soil sensors in the area where the target soil sensor is located during normal operation, and the sum is averaged to obtain an average threshold, and when the target soil sensor is stolen, the instant average moisture data value is significantly reduced and reaches or is lower than the average threshold, and it may be determined that the stolen person is possibly taken out. In addition, when the moisture data are multiple threshold values, the average value of the moisture data of the same target soil sensor in a preset time period of normal operation may be used as an average threshold value, the preset time may be 600 seconds, when the soil sensor is stolen, the moisture data in 600 seconds is obviously smaller than the average threshold value, and at this time, it may be determined that the condition that the stolen person takes out the soil may occur.
The detection of the position change information may be that a GPS positioning device is used to obtain GPS positioning data and transmit the GPS positioning data to a main control unit for processing, and a storage element of the main control unit is used to sort the GPS position information in a time-stamped manner and compare N with N-1 position information according to a queue data structure manner, where N is the GPS position information at the last time, and N-1 is the GPS position information relative to the last time, and a change distance value of the final GPS position information is obtained through calculation by the main control unit, for example, the working time is divided into 1 to 24 hours, the position information of the GPS is a at 8h30min, and the position information of the GPS is changed into a +0.75 (the unit may be meters) at 8h45min, so that it can be determined that a situation that a thief may leave the soil sensor area where the thief is located.
In order to enable a user to know the current state of the soil sensor in time, after the alarm is determined to be performed, alarm indication information is sent to a user terminal, wherein the alarm indication information is used for indicating an alarm type, and the alarm type comprises the following steps: at least one of the first alert signal, the second alert signal, and the third alert signal.
The server receives at least one of the first alarm signal, the second alarm signal and the third alarm signal within a preset time period; and when determining that at least two alarm signals of the first alarm signal, the second alarm signal and the third alarm signal are received, the server informs alarm equipment in the soil sensor to alarm and sends alarm indication information to a user terminal.
Specifically, the second threshold of the vibration frequency may be 7 times, and when the vibration frequency is greater than the threshold, the main control unit generates an alarm signal 1; when the moisture data is smaller than a third threshold value, which can be 0%, the main control unit generates an alarm signal 2; when the GPS positioning data is acquired and transmitted to the main control unit for processing, the storage element of the main control unit sequences the GPS position information in a time marking mode and compares N and N-1 position information according to a queue data structure mode to obtain a final change distance value of the GPS position information, wherein the distance value is greater than a fourth threshold value, the fourth threshold value can be 1m, and the main control unit generates an alarm signal 3.
In some embodiments of the present application, when the main control unit receives the alarm signal, the main control unit sends an alarm indication message to the user terminal, where the user terminal may be a mobile phone, a computer, or a server device of a user. The alarm indication information indicates alarm types, and the types comprise: vibration times, water data, GPS position change data.
According to the above embodiment, when the server sets a preset time, which may be 600 seconds, within which the server receives an alarm signal, a message is transmitted to the user of the soil sensor through the communication unit. And when the server receives two or three alarm signals within the preset time, sending an alarm instruction to the soil sensor, wherein the alarm instruction can be a sound or flash alarm through a main control unit of the soil sensor and an alarm device.
It should be noted that the communication unit may be an 2/3/4G module, or a wireless network transmission module (wifi module), or a remote communication protocol module (lora module), and the alarm device may be a buzzer alarm, a strong light alarm, a vibration alarm, or a remote alarm controller. A power source, which may be a low voltage long endurance battery, is provided in the structure of the soil sensor.
Taking the flow shown in fig. 3 as an example, the anti-theft alarm method for the soil sensor provided by the embodiment of the present application includes the following processing steps:
step S302, starting to execute the program;
step S304, judging whether the vibration amplitude of the soil sensor is greater than a threshold value, executing the next step when the vibration amplitude is greater than the threshold value, and returning to the step S302 when the vibration amplitude is less than the threshold value;
step S306, sending a wake-up signal to the main control unit;
step S308, judging whether the main control unit is in a dormant state, executing the next step when the main control unit is in the dormant state, and entering a working mode when the main control unit is not in the dormant state;
step S310, awakening the main control unit through an awakening signal;
step S312, the main control unit enters a working mode;
step S314, judging whether the equipment is moved, if the equipment is moved, executing the next step, and if the equipment is not moved, returning to the step S302;
step S316, a notification is issued.
It should be noted that, in the above embodiment, after the main control unit generates the alarm signal, the alarm signal needs to be sent to the user terminal, where the user terminal may be a mobile phone, a computer, or a server device of a user, and the main control unit may send all existing monitoring data in the soil sensor to the user terminal while sending the alarm signal, so that the data in the soil sensor can be backed up when the soil sensor is stolen, thereby avoiding loss of important monitoring data and increasing loss of the user.
According to another aspect of the embodiments of the present application, as shown in fig. 6, there is provided a burglar alarm method of a soil sensor, including: acquiring an environment state value of the environment where the soil sensor is located, wherein the environment state value is used for quantifying the environment state of the environment where the soil sensor is located; judging whether the environment state value meets a first condition or not; and determining whether to alarm or not according to the judgment result.
Step S602, obtaining an environment state value of the environment where the soil sensor is located.
Specifically, the environmental status is usually determined by various factors, and the environmental status is generally an unquantized distribution parameter, and based on the above problem, the embodiment extracts the environmental status value for the parameter associated with the soil sensor theft prevention to further quantify, for example, the moisture data is taken as a quantification parameter alone, and the calculation is performed in the manner of soil moisture content percentage. By quantifying the environmental parameters, the calculation of the embodiment is more convenient and scientific.
Optionally, the step of acquiring an environmental state value of an environment in which the soil sensor is located includes at least one of: acquiring the times that the reading of the vibration sensor in a first time period is greater than a first threshold value, and taking the times as the environmental state value; acquiring moisture data of the environment collected by the soil sensor, and taking the moisture data as the environment state value; and acquiring the current detection time of the soil sensor and the position change information of the last detection time of the current detection time.
Specifically, acquiring the number of vibrations of the vibration sensor requires counting the number of times collectively over a period of time. For example, a value of the number of vibrations per 600 seconds may be set to a, and when the value of a is greater than 5 (a first threshold value), the number of vibrations is taken as the environmental state value. The moisture data can be obtained by utilizing a humidity detection head in the soil sensor, for example, a chemical humidity detection head or a physical expansion coefficient humidity detection head and the like can be adopted. The detection of the position change information can be realized by utilizing a GPS positioning device to acquire GPS positioning data and transmitting the GPS positioning data to a main control unit for processing, and a storage element of the main control unit sequences the GPS position information in a time marking mode and compares the position information of N and N-1 according to a queue data structure mode to obtain the change distance value of the final GPS position information.
According to the above embodiment, the moisture data may be a soil moisture percentage value obtained by the moisture detection device, and the third threshold may be an average threshold of one or more thresholds.
