In accordance with the present invention, an agricultural machinery management adapter (smart adapter), which is implemented to be attachable to an agricultural machine, is configured to monitor status information of an agricultural machine.

The Farm Machine Management Interface (AMMI) for communication between the farm equipment management adapter 20 and the operator mobile terminal 30 is performed based on RESTful web service and web socket.

An agricultural machinery management interface (AMMI) for communication between the farm equipment management adapter 20 and the farm equipment remote management apparatus 40 is performed based on the RESTful web service.

An agricultural machinery sensor interface (AMSI) for communication between the agricultural machinery management adapter 20 and the sensors installed in the farm machinery 10 is performed based on sensors and serial inputs.

1, an agricultural machinery management adapter 20 includes an agricultural machine interface module (AMIM) 21 for interfacing with an agricultural machine 10, various sensing information transmitted from an agricultural machine interface 21, A monitoring / diagnosis unit (AMDM) 22 for receiving, analyzing, diagnosing, and detecting an abnormality of a diagnosis result, and storing sensing information and repair information of various sensors installed in the agricultural machinery An adapter web service module (AWSH) 24 for providing sensing information and a setting function of the farm machinery 10 to the driver's mobile terminal 30, a storage unit (database) 28, a mobile terminal 30 Or a wireless communication unit 23 for communicating with the agricultural machinery remote management apparatus 40.

The wireless communication unit 23 has a Wi-Fi wireless communication function and a broadband mobile communication wireless function.

The Web service unit 24 of the farm equipment management adapter 20 performs the log-in and the farm equipment management requested by the driver's mobile terminal 30 using the RMI-based web service-based farm equipment management interface (AMMI). In addition, the adapter web service unit 24 transmits important status information diagnosed by the agricultural equipment management adapter 20 to the mobile terminal 30, using an agricultural machine management interface (AMMI) implemented as a web socket.

The agricultural machine sensing interface between the sensor installed in the agricultural machine 10 and the agricultural equipment management adapter 20 uses a serial input.

Between the driver mobile terminal 30 and the farm equipment management adapter 20, Wi-Fi communication is used as an agricultural machinery management interface (AMMI). The driver mobile terminal 30 can access the RESTful web service section 24b of the agricultural equipment management adapter 20 to receive the entire agricultural equipment information, set the farming system monitoring period, or set the gyro sensor (operation angle).

1 includes an analysis and diagnosis section 22a for analyzing and diagnosing the abnormality of the related operation based on the sensing values of the plurality of sensors, A warning unit 22c for generating a warning message when an abnormality occurs in the diagnosis result of the analysis and diagnosis unit 22a, a control unit for outputting a warning message and repair information to the wireless communication unit 23 22b.

1 includes a state sensing unit 21 for receiving a sensing signal sensed by a plurality of sensors of an agricultural machine and outputting the sensed signal to an agricultural machinery monitoring / diagnosis unit, And a power adjusting unit 22 for outputting power.

The agricultural machinery monitoring / diagnosis section 22 periodically monitors the state of the agricultural machinery, and analyzes the state (normal / warning / abnormal) of the sensor to diagnose the problem or stability condition of the agricultural machine.

The agricultural machinery monitoring / diagnosis section 22 manages consumable and periodic inspection cycles by using the operating time of the agricultural machinery measured by the agricultural equipment management adapter 20. The inquiry of the consumable management / survey cycle is requested by the operator mobile terminal 30 by logging in to the farm management adapter 20 and provided to the driver mobile terminal 30. [

When the driver requests management of the farm equipment, the mobile terminal 30 of the driver transmits a Web service based farm equipment interface request to the farm equipment management adapter 20. [ At this time, the driver's mobile terminal 30 can use, for example, a hybrid application-based graphical user interface (A-GUI).

On the other hand, the agricultural equipment management adapter 20 can notify the driver's mobile terminal 20 asynchronously to the critical state information that has been diagnosed by using the agricultural equipment management interface implemented as a web socket.

Further, the agricultural machinery management adapter 20 transmits agricultural machinery status information to the remote management apparatus 40 by using a farm agent management interface based on CoAP (Constrained Application Protocol). On the other hand, the farm equipment remote management apparatus 40 provides a RESTful web service based user interface (M-GUI) and a CoAP based farm equipment management interface.

The farm state emergency notification unit 42 of the farm management system remote management apparatus 40 registers the state of the agricultural machinery system in the family mobile terminal 60 registered in advance using the Google FCM-API (Firebase Cloud Messaging-Application Programming Interface) Or push service provider. The technology for pushing the data to the mobile terminal by the server is a well-known technique, and thus detailed description of the configuration is omitted.

The emergency mobile terminal 60 informs the agricultural machinery remote management apparatus 40 of the mobile phone number, the mobile platform (Android, iOS), the recognition flag upon reception of the push service, the activation flag of the SMS and the FCM information to provide. The FCM information includes a registration ID (register ID) for the Android platform allocated from the push server. Further, the remote management apparatus has push-related information of the emergency mobile terminal 60 in order to transmit the push signal to the emergency mobile terminal 60. [

2 is a communication configuration diagram of the agricultural equipment management adapter 20 and the agricultural machinery remote management apparatus 40 of FIG. The farm equipment remote management apparatus 40 receives and manages status information from the farm equipment management adapter 20. 2, when the agricultural machinery remote management apparatus 40 receives the agricultural machinery abnormality status information from the agricultural equipment management adapter 20, the emergency management server 40 registers the emergency agent 60 registered in advance via the SMS-API or the push server 50, Or send an anomaly message to the maintenance company. The anomaly message includes a push message or an SMS message.

Also, the agricultural machinery remote management apparatus 40 provides the information received from the agricultural machinery management adapter to the remote manager, the emergency mobile terminal 60, or the mobile terminal of the family or maintenance company, or the driver mobile terminal based on the RESTful web service. The emergency mobile terminal 60 includes a driver of an agricultural machine, a family member of a driver, a friend of a driver, or a mobile phone of a maintenance company.

When the agricultural machinery remote management apparatus 40 provides agricultural machinery status information received from the agricultural machinery management adapter to the driver's mobile terminal, when the driver's mobile terminal can not communicate with the agricultural machinery management adapter, To receive agricultural machine status information from the farmer.

According to the present invention, the farm equipment remote management apparatus 40 is set to receive a response message for the push message from the emergency mobile terminal 60 after transmitting the push message to the emergency mobile terminal 60.

FIG. 3 is a flowchart of the abnormal state warning notification method of the agricultural machinery remote management apparatus 40 of FIG. As shown in FIG. 3, the agricultural machinery remote management apparatus 40 periodically receives the farm condition information from the farm management adapter 20 (S1). If it is determined that the state of the agricultural machinery system is abnormal (S2), a push message (state information, push recognition flag) according to the push registration of the user is generated (S4). The farm equipment remote management apparatus 40 transmits a push message to the push server 50 (S5). If the push acknowledgment flag is turned on (S6) after transmitting the push message, a success response signal indicating that the push message has been properly transmitted from the push server 50 is received (S7). It is determined whether a push recognition signal is received from the emergency mobile terminal (S8). When the push recognition message is received, the notification processing is completed (S9).

However, if the push-recognition signal is not received from the emergency mobile terminal, it is determined whether the SMS flag is on (S10). If the SMS flag is ON, the state information of the farm equipment is transmitted to the emergency mobile terminal 30 via SMS (S11).

In this manner, it can be confirmed that the abnormal state message is normally transmitted to the emergency mobile terminal 60 by receiving the push acknowledgment signal after transmitting the abnormal state push message of the agricultural machine.

In the following, the detailed functions of the agricultural machinery monitoring / diagnosis section 22 of the agricultural equipment management adapter 20 will be described in detail. The analysis and diagnosis section 22a of the agricultural machinery monitoring / diagnosis section 22 periodically monitors the state of the agricultural machinery and analyzes the state (normal / warning / fault) of the sensors to diagnose a failure or a safety state. The analysis and diagnosis unit 22a of the agricultural machinery monitoring / diagnosis unit 22 manages consumables and periodical inspection cycles using the running time of the agricultural machinery measured by the agricultural equipment management adapter 20.

For example, the analysis and diagnosis unit 22a of the farming system monitoring / diagnosis unit 22 determines that the state of the engine oil is normal when the running time is less than 95 hours, ) And a critical state for more than 110 hours.

For example, when the temperature of the engine water temperature is less than 90 degrees, it is normal, 90 degrees or more and less than 110 degrees are warning, and 110 degrees or more is serious. The state diagram defined for diagnosing the state of the agricultural machinery in the agricultural machinery monitoring / diagnosis section 22 can be defined as shown in FIG. 4, for example. As shown in FIG. 4, when the continuous second warning state occurs in the normal state, the state transits to the warning state, and when the normal state occurs twice in succession, the state transitions to the normal state. When a serious condition occurs in any state, it transitions to a temporary pseudo-C state. If a warning or steady state is detected in a severely related state, it transitions to a temporary Pseudo-W or Pseudo-N state.

The analysis and diagnosis unit 22a of the agricultural machinery monitoring / diagnosis unit 22 periodically monitors the state of the agricultural machinery and notifies the control unit 22b of important state information that has been diagnosed. The control unit 22b notifies the driver's mobile terminal 30 of the farm equipment management interface (AMMI), which is implemented as a web socket, when a notification of the farm equipment status is required.

According to the present invention, the farm machine monitoring / diagnosis section 22 is implemented, for example, as a raspberry pie board. Accordingly, the sensed values of the sensors of the agricultural machine 10 are input to the general-purpose input / output (GPIO) pins of the raspberry chip board. Table 1 shows the types of sensors required for the agricultural machinery management service and the manner of operation, and pin number assignments of the GPIOs of the agricultural machinery monitoring / diagnosis unit 22.

Agricultural Machinery Management
Sensor type How it works /
Operating contact
GPIO Fuel Filter Water Sensing level on, off  23 Battery charge level on, off  4 Engine water temperature sensing level  Thermistor 24 Antifreeze amount level on, off 25 Transmission oil level level on, off 18 Steady state Gyro Angular velocity 10

On the other hand, the agricultural machinery state sensing unit 210 of the agricultural machine interface unit (AMIM) 21 periodically receives status information from the sensors installed in the agricultural machinery.

Since the agricultural machine state sensing unit 210 receives the sensing value from the plurality of sensors provided on the farm machinery 10 as a serial signal line, it is effective that the agricultural machine state sensing unit 210 is separately input according to the installation position of the sensor. For this, as shown in FIG. 5, there are provided a first slave sensing unit 11 including sensors installed at the engine site, a second slave sensing unit 12 including a transmission and a hydraulic pressure sensor, And a third slave sensing unit 13 including a sensor. In this way, the agricultural machinery state sensing unit 210 connects the sensing value from each sensor of the agricultural machine 10 via the serial signal line and receives it. This is because the manufacturer of the agricultural machinery manufactures the ECU and the CAN-related identifier (sensor ID) Is not open to the public.

6, the agricultural machinery state sensing unit 210 includes an RPM detection circuit 212 for detecting the engine speed of the agricultural machine 10, a contactless switch unit 211 for receiving a sensed value as a level signal, An AD converter 213 for receiving the output signal of the contactless switch unit 211 and the output signal of the RPM detection circuit 212 and converting the signal into a digital signal and outputting the digital signal to the agricultural machine monitoring diagnosis unit 22, And a gyro sensor input unit 214 for receiving sensor values of a gyro sensor installed in the gyro sensor.

The contactless switch unit 211 receives a sensor level value such as an engine part of an agricultural machine, a transmission oil, and an oil pressure.

Since each sensor installed in the farm machine 10 operates as a level sensor, noise and chattering occur when monitoring the state of the agricultural machine by driving the relay as a relay, so that accurate level sensing may not be performed . Accordingly, in the present invention, a photo-coupler 211b operating as a contactless switch as shown in FIG. 7 is used in place of the relay for accurate level sensing.

Meanwhile, the A-D converter 213 of the agricultural machinery state sensing unit 210 is implemented as an 8-channel converter. The A-D converter 213 converts an analog signal sensed for various state sensing of the agricultural machine 10 into a digital signal. Each sensor installed in the agricultural machine 10 senses a displacement, and a displacement value sensed by the sensor is used as an input signal to the A-D converter 213.

In the present embodiment, a plurality of sensors used for detecting an abnormal state of the farm machinery 10 include a fuel filter moisture sensor, a battery charge sensor, an engine water temperature sensor, an antifreeze quantity sensor, and a transmission oil quantity sensor, The sensing value is input to the AD converter 213. Meanwhile, the sensing value of the gyro sensor is input through a separate gyro sensor input unit.

1. On-off sensing and event generation of fuel filter moisture sensor

The analyzing and diagnosing unit 22a of the farming apparatus monitoring / diagnosis unit 22 may notify the control unit 22b of an abnormality (abnormality) when the warning is sensed, And outputs a signal. The control unit 22b transmits a warning message and repair information to the driver's mobile terminal 30 through the wireless communication unit 23. [

2. Battery on-off sensing and event occurrence

Install a sensor that detects the charge voltage of the battery by charging the battery with the voltage generated from the generator of the agricultural machine. A voltage of 12V (24V) is generated when the generator operates normally when a voltage is generated from the generator, and a voltage of 0V is generated when a warning or abnormality occurs in the operation of the generator.

The analysis and diagnosis unit 22a of the agricultural machinery monitoring / diagnosis unit 22 diagnoses the abnormal state when the voltage of the storage battery is 0V and outputs an abnormal signal to the control unit 22b. The control unit 22b immediately transmits a warning message and repair information to the driver's mobile terminal 30 via the wireless communication unit 23 and transmits an error signal to the remote management apparatus 40 Have the emergency notification service run.

3. Measure temperature value of engine water temperature and warn according to value

The engine temperature sensor uses a thermistor, which is a semiconductor element having a negative resistance characteristic, and the resistance value decreases linearly from 100 kΩ to 150 Ω. The temperature gauge operates by detecting a resistance value of 18.8 K?% At -20 占 폚, 1.136 K?% At 40 占 폚, and 150?% At 100 占 폚.

The agricultural machinery monitoring / diagnosis unit 22 monitors the sensed value and diagnoses the abnormal state, and outputs an abnormal signal to the control unit 22b. The control unit 22b transmits a warning message to the driver's mobile terminal 30 via the wireless communication unit 23 and transmits a warning message to the driver's mobile terminal 30 via the remote management device 40. [ Notify the vendor.

 4. On-off sensing and event generation of anti-freeze amount

Most farming systems do not detect the lack of antifreeze in the radiator. Therefore, according to the present invention, an auxiliary tank is provided beside the radiator, a cap of the radiator is connected to the auxiliary tank by a hose, and a sensor is attached to the auxiliary tank.

When the antifreeze is heated, the antifreeze flows into the auxiliary tank through the hose by pressure, and when the antifreeze is cooled, the antifreeze of the auxiliary tank is sucked into the radiator again. Using this principle, whether or not the amount of the antifreeze in the radiator is insufficient can be detected by sensing whether or not the amount of the antifreeze in the auxiliary tank is maintained at a constant level by the sensor in the auxiliary tank.

Therefore, when the antifreeze in the auxiliary tank senses less than a certain level, the analysis and diagnosis section 22a diagnoses the abnormal state and outputs an abnormal signal to the control section 22b.

The control unit 22b immediately transmits a warning message to the driver's mobile terminal 30 via the wireless communication unit 23 when an abnormality signal is input, And transmits an abnormality signal to the remote management apparatus 40 to cause the maintenance company to execute the emergency notification service.

5. Safety angle measurement and angular warning

Since the agricultural machine is occasionally overturned during operation, it may cause a catastrophic accident to the driver. Therefore, angle measurement is performed using an angle measuring device such as a gyro sensor. The gyro sensor is installed in the driver's seat of the farm machinery 10.

If the measurement angle of the angle measuring device is 0 to 20 degrees, set it to the normal operating phase. If it is 20 to 25 degrees, set the warning level. If it is more than 30 degrees, set it as the dangerous level.

In this manner, the agricultural machinery monitoring / diagnosis unit 22 receives the detection angle of the gyro sensor, and outputs the abnormal signal to the control unit 22b when the detection angle is diagnosed as the warning phase. The control unit 22b transmits a warning message to the mobile terminal 30 of the driver through the wireless communication unit 23. [ Accordingly, when the angle of the angle measuring apparatus is at a dangerous level, the warning message is transmitted to the driver's mobile terminal 30. [

6. Transmission oil level

The oil level of the transmission is located at the upper limit of the oil level sensor when the temperature of the oil is 80 ° C at the engine starting condition (800rpm) and at the lower limit when the temperature of the oil is 40 ° C.

When oil warning is detected, the agricultural machinery monitoring / diagnosis section 22 outputs an abnormality signal to the control section 22b at the time of diagnosing the abnormal state, because the oil warning is a cause of a fatal trouble to the agricultural machinery. The control unit 22b immediately transmits a warning message to the driver's mobile terminal 30 via the wireless communication unit 23 or performs a notification service to the maintenance company via the remote management device 40. [

7. Engine oil change interval (operating time)

The analysis and diagnosis unit 22a of the agricultural machinery monitoring / diagnosis unit 22 receives the on / off signal of the starting of the agricultural machine, and counts and accumulates the operation time. When the operation time reaches 90 hours, for example, the engine oil is diagnosed as the replacement time and the diagnosis result is provided to the control unit 22b. The control unit 22b performs a notification service to the driver's mobile terminal 30 through the wireless communication unit 23. [

8 is a circuit for sensing the engine speed RPM by reading the AC voltage generated in the ring gear of the engine, in order to monitor the engine condition. The input to the RPM sensing circuit 242 is an AC voltage generated by a magnetic pickup sensor (not shown) of the ring gear (gear) and the output is used for RPM sensing in the Raspberry chip, which is the monitoring / Voltage and frequency.

To generate a normal frequency output at the RPM sensing circuit 242, the input of the ac voltage should be Vp-p 3V or higher at the ring gear.

8, the RPM detection circuit 242 includes a plurality of resistors and a plurality of diodes 242a and 242f connected to an input stage, an OP amplifier 242g, a Zener diode (not shown) connected to the output terminal of the OP amplifier 242g 242m. The connection of the Zener diode to the output of the OP amplifier with 3.3V is intended to produce a 3.0V output required by the Raspberry board,

The equation for calculating the engine speed,

(rgear = 127: number of ring gears, 120: angular velocity)

As a result of measuring the output waveform Vo, the frequency was detected as 1.994 kHz,

(rgear:링기어수)

(rgear: number of ring gears)

There may be a small difference between the RPM measured using the output frequency in the RPM detection circuit 242 and the RPM calculated in Equation 1. [

9 shows waveforms of changes in the output voltage according to the input voltage of the RPM detection circuit 242 in Fig.

If the RPM input voltage is 2kHz sine wave of about 2pV-p, the input voltage is low and no output is seen. When the RPM input voltage is higher than Vp-p 3.0V, a voltage of about 3.92V is outputted from the output waveform as shown in FIG. 9 (a). The zener diode 212m of 3.3V is connected to the output terminal of the OP-amplifier 212g to output the voltage of 3.0V required by the raspberry board as the agricultural / monitoring diagnosis unit 22a as shown in Fig. 9 (b).

The power adjusting unit 220 of the agricultural machine interface unit 21 of FIG. 1 will be briefly described. Since the agricultural machinery has a poor working environment and uses a high load, an overvoltage may occur in the generator, which may have a serious effect on various electronic parts. The agricultural machine monitoring / diagnosis unit 22 implemented as a raspberry chip board can not directly use the voltage supplied from the agricultural machine generator because the GPIO input voltage is 3.3V. Therefore, power supply adjustment is required for stable power supply from the 12 / 24V power supply to the agricultural machinery monitoring / diagnosis unit 22.

Therefore, it is preferable that the power adjuster 220 adjusts the power source of 12 V or 24 V agricultural machine to a power source of 5 V and supplies it to the agricultural machinery monitoring / diagnosis unit 22.

According to the above-described configuration, productivity improvement and safety can be provided through prior management of agricultural machinery by means of an agricultural equipment management adapter and an agricultural equipment management system, in which ICT and agricultural technology are integrated. The agricultural machinery management can be easily implemented by attaching to the agricultural machinery for the agricultural machinery management adapter and transmitting the abnormal state of the agricultural machinery to the driver's mobile terminal.

In addition, it is possible to notify the driver's mobile terminal when abnormal conditions are detected by analyzing various operation states (normal / warning / fault) of the agricultural machine, and notify the emergency contact information when the abnormal state of the agricultural machine is remotely detected, Can respond. Further, it is possible to remotely manage the abnormal state of the agricultural machinery, and to make sure that the abnormal state message is notified to the emergency mobile terminal or repair company.

In addition to the sensor for detecting the state of the agricultural machinery in the above-described embodiment, the sensor further includes an engine oil pressure sensor, an engine overheat sensor, an engine filter clogging sensor, an air cleaner indicator sensor, and the like Of course.

In the above-described embodiment, the state information of the agricultural machinery, which is sensed by the agricultural machinery management adapter, is transmitted to the remote management apparatus through the Agricultural Network Management Interface (AMMI) based on the CoAP. At this time, the remote management apparatus can receive the state information of the agricultural machinery through the wireless communication unit having the wide area wireless communication function.

According to another embodiment, a method may be considered in which the remote management apparatus receives status information of the agricultural equipment from the agricultural equipment management adapter when the remote management apparatus does not have the wide area wireless communication function, i.e., does not have the wireless communication unit .

The first method is to inquire the state of the agricultural machinery in the remote management device by using push and SMS. It is a method of inquiring the status of agricultural machinery in the remote management device with respect to the agricultural equipment management adapter having the short-range wireless communication function (e.g., WiFi).

First, the driver mobile terminal transmits push-related information to the remote management apparatus via the agricultural machine management interface (AMMI) at the time of execution of the hybrid application (step 1) in order to receive the inquiry request of the agricultural machinery status from the remote management apparatus. The push-related information includes a telephone number of the driver smartphone, a mobile platform (Android, iOS), a recognition flag upon receiving a push service, an SMS activation flag, and a registration ID (register ID) allocated from a push server.

Then, the remote management apparatus pushes a message requesting inquiry about the state of the agricultural equipment to the driver's mobile terminal (step 2). Then, in the hybrid application of the driver mobile terminal, the status information of the farm equipment is inquired with the farm equipment management adapter through the farm equipment management interface (AMMI) (step 3).

The hybrid application of the driver mobile terminal automatically transmits the status information of the farm equipment received from the agricultural equipment management adapter to the remote management device via SMS (step 4). The mobile terminal of the driver transmits the location information of the mobile terminal together with the status information of the farm equipment to the remote management apparatus when the SMS is transmitted. Here, the remote management apparatus may be connected to the SMS server and may have an SMS transmission / reception function.

In the second method, the remote management apparatus requests remote farming status inquiry using SMS, and the method is as follows.

First, the remote management apparatus requests status information of the agricultural machinery to the driver mobile terminal by using the SMS. In the next step, the driver's mobile terminal requests the agricultural machinery status information from the agricultural machine management adapter (step 2-1). In the next step, the hybrid application of the driver's mobile terminal uses the agricultural machine management interface (AMMI) Information is inquired (step 2-2).

The hybrid application of the driver mobile terminal automatically transmits the status information of the farm equipment received from the agricultural equipment management adapter to the remote management device via SMS (Steps 2-3). The driver mobile terminal transmits the location information of the mobile terminal together with the farm condition information at the time of SMS transmission.

The third method is to request remote farming system status inquiry from repair shop or customer management center using SMS. First, the repair shop or the customer management center requests the driver's status information of the farm equipment using the SMS (step 3-1). Next, the driver requests the agricultural machinery management adapter using the request message of the hybrid app of the mobile terminal (e.g., the status transmission menu using the SMS) (step 3-2).

Next, the hybrid application of the driver mobile terminal inquires the status information of the farm equipment through the farm equipment management interface (AMMI) (Step 3-3).

Then, the agricultural machinery management adapter returns the current agricultural machinery status information (status information, repair shop article or repair shop telephone number) to the driver's mobile terminal for responding to the repair shop or customer management center by SMS (steps 3-4). Then, the driver mobile terminal sends an SMS to the telephone number in the return information (steps 3-5). At this time, the driver mobile terminal transmits the location information and the status information of the driver's mobile terminal together with the SMS when transmitting the SMS.

With this configuration, when the remote management apparatus does not have the wide area wireless communication function, the remote management apparatus can receive the state information of the agricultural equipment from the agricultural equipment management adapter.
