Description

TECHNICAL FIELD [0001] The present invention relates to an IoT-based environment adaptive actuator control system,

The present invention relates to an environment adaptive actuator control system for adjusting the opening and closing of a valve in accordance with sensing information collected by a sensor, and more particularly, to an environment adaptive actuator control system for autonomously determining a real-time situation based on sensing information collected around a valve provided with an actuator To an environment-adaptive actuator control system that automatically controls valve opening and closing.

Generally, in an actuator in which a movable part is displaced by the supply of a pressure fluid (for example, a pressure gas), when the frequency of use or the number of times of operation (operation time, use time) do.

However, conventionally, even a normal actuator that is not undergoing deterioration is replaced by management, resulting in a wasteful cost. Further, in the market, it is necessary to shorten the moving time (tact) of the moving part of the actuator and increase the tacticity, thereby improving the productivity of the facility using the actuator and reducing the cost of the product produced by the facility . To do this, it is desirable to automatically and numerically manage the actuator and improve the manageability, rather than setting the management time at the judgment of the operator.

In general, the deterioration of an actuator using a pressure fluid is considered to be caused by a condition of a load depending on the actuator, and an aging of a fluid pressure device such as an air pressure device including an actuator. If the occurrence of an abnormality in the actuator can be detected before the failure of the actuator by the deterioration due to the change of the tact or the like occurs, the fluid pressure device can be used before the end of life cycle. So that it can be operated with good efficiency.

Here, instead of the method of performing management on the basis of the frequency of use or the number of times of operation (operation time, use time) as described above, various types of abnormality detection systems including a failure prediction function for automatically and numerically detecting an abnormality of the actuator Has been proposed.

1 is a configuration diagram of an abnormality detection system of an actuator according to the related art. Referring to FIG. 1, the abnormality detection system 100 detects an abnormality of an actuator by measuring a fluctuation of a flow rate or pressure of a pressure fluid.

In this anomaly detection system 100, a pressure fluid is selectively supplied from the fluid pressure source 102 to the actuator 106 through the directional switching valve 104. The piston 110 connected to the piston rod 108 is displaced in the left-right direction in FIG. 1 between the one end portion 116 and the other end portion 118 of the actuator 106 in the actuator 106 as a cylinder.

More specifically, the directional control valve 104 is a four-way five-port single acting electromagnetic valve having a solenoid 112 and a spring 114. That is, when the solenoid 112 is energized by supplying a control signal (operation command) from the outside, the directional switching valve 104 causes the pressure fluid from the fluid pressure source 102 to flow through the port 120 to the actuator 106, And the fluid (pressure fluid) at the other end 118 is exhausted to the outside through the port 122. At the same time, Accordingly, the piston 110 is displaced from the one end portion 116 toward the other end portion 118.

At this time, when the supply of the control signal stops, the direction switching valve 104 supplies the pressure fluid from the fluid pressure source 102 to the other end portion 118 through the port 122 by the action of the spring 114 And simultaneously discharges the pressure fluid of the one end portion 116 through the port 120 to the outside. Accordingly, the piston 110 is displaced from the other end portion 118 toward the one end portion 116.

In the middle of the pipes 123 and 125 connecting the directional control valve 104 and the ports 120 and 122, couplings 124 and 126 constituted by connecting a throttle valve and a check valve in parallel are respectively disposed and installed .

In this case, there is a possibility that pressure fluid may leak from each part of the anomaly detection system 110 to the outside, as indicated by the broken line arrows in Fig. Specifically, (1) piping 123, 125, 127 between the fluid pressure source 102, the directional control valve 104 and the actuator 106, (2) the directional control valve 104, (3) (Not shown) between the cylinder 108 and the piston rod 108 and the cylinder, and (4) the pressure fluid may leak from the couplings 124, 126 to the outside.

Also in the interior of the actuator 106, there is a possibility that the pressure fluid may leak between the one end portion 116 and the other end portion 118 through the piston 110 and the unshown packing between the piston 110 and the cylinder .

Here, in the abnormality detection system 100, a flow meter and a pressure gauge (not shown) are disposed and installed in the respective pipes 123, 125, and 127, and the flow rate of the pressure fluid is measured in each flow meter. Measure the pressure.

Therefore, it is possible to measure the fluctuation of the flow rate and the pressure of the pressure fluid, so that it is possible to detect an abnormality in the portion where the pressure fluid leaks and to perform the component replacement before the failure.

2 is a configuration diagram of an abnormality detection system of an actuator according to the related art. 2, the abnormality detection system 130 detects an abnormality of the actuator 106 based on the movement time of the piston 110. [ The abnormality detection system 130 includes a controller such as a PLC (Programmable Logic Controller) that supplies a control signal to the solenoid 112 from the output unit 132a, in addition to the respective components of the abnormality detection system 100 A first sensor 134 disposed at one end 116 of the actuator 106 and a second sensor 136 disposed at the other end 118 of the actuator. The anomaly detection system 130 is not provided with the couplings 124 and 126 (see FIG. 1). A muffler 138 is disposed and installed in the exhaust passage of the pressure fluid from the one end 116 or the other end 118 of the actuator 106.

The first sensor 134 detects the piston 110 displaced at the one end portion 116. The second sensor 136 detects the piston 110 displaced at the other end 118. The detection signal indicating the result of detection of the piston 110 by the first sensor 134 or the second sensor 136 is inputted to the input unit 132b of the control device 132. [ Therefore, the control device 132 calculates the time (the movement time of the piston) from the time point when the control signal is outputted to the direction switching valve 104 until the detection signal is input (the time point when the displacement operation of the piston is completed) And detects an abnormality of the actuator 106 based on the measured movement time.

On the other hand, IoT (Internet of Things) means a concept that can perform mutual communication by connecting all communicable objects to a network. All objects that can be systematically recognized are classified as Things or Objects, which include near and far communication functions including RFID, objects (or sensor nodes) capable of producing and using data, such as sensors, .

In addition, the Internet has expanded beyond the computer-only network to the areas of mobile and embedded devices, and various web contents have been created and shared by an enormous amount of intelligent objects (e.g., wireless sensors, actuators or embedded devices) .

Although the existing Internet has been used among devices such as computers with sufficient resources, in the extended IoT environment including the inter-object communication such as the sensor and the RFID, the data is transmitted based on the communication between the devices with relatively limited resources Since it is necessary to be able to receive and control information from objects by sending and receiving, there is a need for a technique to support this with a minimum of resources.

Recent developments of microprocessor and wireless communication technologies are at the practical stage to develop intelligent objects of IoT, but web contents technology of existing Internet environment such as HTTP / TCP, HTML, Javascript is applied to limited environments and devices such as sensor networks It is still too heavy and complicated to fit in.

[ The actuator 100 may further include a storage module (not shown), a switching unit 170, a speed reducer (not shown), etc., connected to the control module 150 and having an IoT platform installed therein. At this time, a plurality of through holes 122 are formed in the case 120 where the sensor module 110 is embedded. This is to enable the sensor module 110 to smoothly detect the information of the surrounding environment by allowing air to flow into the inside and outside of the case 120 through the through hole 122.

The short-range communication module 130 is connected to the IOT gateway 200 through a communication network to transmit sensing information. An antenna 132 may be installed for smooth communication.

The motor 140 is connected to the valve 20 to physically adjust the opening and closing of the valve 20, and a BLDC motor can be used.

The short range communication module 130 may be connected to the flow sensor 30, the pressure sensor 40, or both of them through a communication network provided in the piping 10 so that the flow of the fluid passing through the inside of the piping 10 And to transmit the flow information to the control module 150 of the IoT gateway 200. The short-range communication module 130 is connected to the pump 60 installed in the water tub connected to the pipe 10 in a wireless or wired manner and receives a control signal for the pump 60 from the control module 150, Lt; / RTI > At this time, the flow information includes the output signals of the flow sensor 30 and the pressure sensor 40.

The actuator 100 according to the present invention is connected to the flow sensor 30 and the pressure sensor 40 installed in the piping 10 to collect flow information for confirming the state inside the piping 10, It is possible to collect sensing information from the module 110 outside the piping 10, in particular, the state of the periphery of the valve 20. [

Here, the control target device 50 may be a target device to be automatically controlled by the user, for example, a device such as a heater, an air conditioner, or a dehumidifier. The control target device 50 is normally operated by the wired power supply, and the actuator 100 is installed therein.

For example, the sensor module 110 may include at least one of a gas sensing multi-sensor, a temperature / humidity sensor, a gyro sensor, an infrared sensor, a flame sensor, and a smoke sensor.

More specifically, the gas sensing multi-sensor actuator 100 VOCs in the vicinity (Total Volatile Organic Compounds: TVOC) and carbon dioxide (CO 2) or detects the occurrence of both of these, the TVOC or carbon dioxide (CO 2) Generates an event generation signal and provides the event generation signal to the IoT gateway 200. For example, the gas sensing multi-sensor generates and transmits an event generation signal to the IoT gateway 200 when the TVOC is detected as a certain level value or a management upper limit or when CO 2 is detected as a specific level value or an upper management limit. Thus, the event generation signal generated by the gas sensing multi-sensor includes information on the concentration of TVOC and CO 2 .

The temperature / humidity sensor senses the temperature and humidity around the actuator 100. When the temperature / humidity exceeds the set reference, the controller generates an event signal and provides the signal to the control module 150. At this time, the control module 150 provides the IoT gateway 200 with an event generation signal generated by the temperature / humidity sensor. For example, the temperature and humidity sensor generates an event occurrence signal when the temperature is detected to be 35 ° C or more or below 0 ° C, and generates an event occurrence signal when the humidity is detected as 55% or more or less than 25% . The control module 150 collects the event signal and transmits the event signal to the IoT gateway 200.

Here, the control signal may include at least one of a normal mode control signal, an abnormal mode control signal, and a pump control signal. The normal mode control signal is a signal requesting control of the valve 20 to maintain the valve 20 in an open state and the abnormal mode control signal is a signal for controlling the valve 20 to maintain the valve 20 in a closed state. And the pump control signal is a signal requesting control so that the pump 60 is turned on / off.

[ If necessary, the control module 150 may control the operation of the motor 140 according to the control signal to adjust the opening degree of the valve 20. [ More specifically, the control module 150 controls on / off of the valve 20 and the pump 60 according to the control signal transmitted from the IOT gateway 200.

The control module 150 controls the motor 140 so that the valve 20 is immediately closed when the output signal levels of the flow sensor 30 and the pressure sensor 40 included in the flow information are out of the set range. The control module 150 periodically transmits the flow sensor 30 and the pressure sensor 40 data via the IoT gateway 200 To the IoT server 400, and the IoT server 400 continuously monitors and monitors the flow rate / pressure data to update the threshold value.

The switching unit 170 constituting the actuator 100 according to the present invention acts as a switch to stop the operation or to stop the operation so that the actuator 100 can not proceed any more than the reference force or the hardware when the angle moves. . To this end, the switching unit 170 is electrically connected to the control module 150.

Referring to FIG. 3, an actuator control system according to the present invention includes an IoT gateway 200.

The IoT gateway 200 is wired or wirelessly connected to the router 300. The IoT gateway 200 analyzes the sensing information collected from the actuator 100 to generate a control signal and transmits a control signal to the actuator 100 .

Specifically, the IoT gateway 200 may be connected to the wireless router (300) connected to the actuator (100) through a wired connection, or may be connected to the wireless router (300) And are connected via short-range wireless communication.

If necessary, the IoT gateway 200 may be directly connected to the actuator 100 through short-range wireless communication such as Wi-Fi, as shown in FIG. 7 (B). In this case, the use of the wireless router 300 is unnecessary, but the actuator control system in which the wireless router 300 is not installed can not monitor the actuator 100 desired by the user from a remote place. 7 (B), when the IOT gateway 200 is connected to the wireless router 300 through wired or wireless communication, the user terminal 500 can provide a monitoring function for the desired actuator 100 .
