Description
Technical Field
The present disclosure relates to sensor controllers and sensor assemblies for collecting various operational data of a machine.
Background
Although plant automation equipment is currently being used in large numbers in enterprises and is encouraged by governments, there are practical limitations in utilizing plant automation equipment in small and medium-sized enterprises. That is, not only there is a problem of investment cost requiring a considerable amount of investment in order to use the corresponding automation apparatus, but also there are problems as follows: when the measurement sensor of the automation device is assigned to a component of a product of a certain company, the entire measurement module needs to be replaced when the sensor module for it and its measured values change when its supply is completed and the products of other companies are manufactured. In addition, considerable time and expense is required when the settings of the measurement modules need to be changed, and therefore, in many cases, it is more efficient to take measurements and monitor over time using existing human resources than to use automated equipment.
In addition, each of the sensors of current plant automation devices performs a specific function. For example, a sensor measuring temperature transmits data measured by a terminal combined with a corresponding module and a temperature measuring sensor and modularized to a server or a data server performing management, and an administrator checks information therefor. In addition, such a combined type terminal performs management and measurement control through a complicated connection with a device. However, in the case where a humidity sensor is required in addition to a temperature sensor, there is a burden in terms of costs for modularizing the humidity sensor and the temperature sensor together to additionally manufacture and in terms of time for requiring a new design and in terms of manpower for developing it.

Hereinafter, a system according to an embodiment of the present invention is described in detail.
Referring to fig. 1, the system of an embodiment of the present invention includes a sensor assembly 100, a server 200, and a user terminal 300, which are disposed near a machine 10 in a factory.
A system according to an embodiment of the present invention is a system capable of providing intelligent plant services. Such an intelligent plant service implementation monitors the current operating status of the machine equipment 10 within the plant and immediately notifies a plant manager when the possibility of occurrence of a failure is high or when a failure occurs, thereby making it possible to provide efficiency and convenience for the plant manager to manage the machine equipment 10. In particular, the sensor assembly 100, which will be described later, provides a service based on Internet Of Things (IOT) technology, thereby eliminating the inconvenience Of a plant manager finding the machines 10 one by one and carefully confirming whether there is a problem.
The sensor assembly 100 is an IOT integrated module terminal comprised of at least one sensor. The sensor unit 100 may be provided in the vicinity of the machine 10 in a factory, or may be attached to any surface of the machine 10. Sensor assembly 100 includes sensors for measuring operational data (e.g., temperature, humidity, pressure, power, etc.) of machine 10 and sensors for communicating the operational data to server 200.
An application capable of providing an intelligent factory service may be provided in the user terminal 300. The application program receives the information from the server 200 and processes the information into a form that is easily understood by the user to provide the user with information regarding the status of operation of the machine device 10.
Hereinafter, the structure of the sensor assembly 100 according to an embodiment of the present invention will be described in detail with reference to fig. 2.
The sensor assembly 100 is composed of a plurality of sensors. Specifically, the sensor assembly 100 includes a sensor controller 110, a communication module 120, a measurement sensor 130, and a connector 140.
The sensor controller 110 to the measurement sensor 130 may be physically independent from each other. That is, as shown in fig. 1, the respective sensors may be formed to have a similar hexahedral shape or to have the same physical specifications, and are very easily replaced as desired in a module. For example, even when any one of the sensor controller 110, the communication module 120, and the measurement sensor 130 has a failure or needs to be changed in use, the problem can be easily solved by replacing the corresponding sensor.
In addition, the sensor assembly 100 may also include a bracket. The cradle performs the function of supporting both the sensor controller 110 and the communication module 120. The bracket is formed in an area that can cover the area of the sensor controller 110 and the communication module 120, and a partition wall is formed at an edge area, thereby also realizing a function of fixing the sensor controller 110 and the communication module 120 so that the sensor controller 110 and the communication module 120 do not come off to the outside. At this time, the sensor controller 110 and the communication module 120 may be disposed in a form of being stacked on each other on the support.
Hereinafter, the functions of the respective sensors will be described in detail.
The sensor controller 110 receives the operation data from the measurement sensor 130 and transfers the operation data to the communication module 120 to transmit the operation data to the server 200 and collect the operation data. At this time, the sensor controller 110 is connected with at least one measurement sensor 130. Even if the existing connected measurement sensor 130 is replaced with another kind of measurement sensor 130 by replacement or addition of the measurement sensor 130, the sensor controller 110 can receive the operation data of the currently connected measurement sensor 130 and recognize the operation data.
For example, various sensors such as a temperature sensor, a pressure sensor, a humidity sensor, a current/voltage sensor, a power sensor, etc. may be connected to the sensor controller 110. Further, the sensor controller 110 functions to simply forward the electric signal values (i.e., A/D signal values: signals converted from analog to digital) of the measuring sensors 130 to the server 200 when the firmware is loaded on the server 200, and when the firmware for all the sensors is downloaded and installed in the sensor controller 110, the sensor controller 110 can recognize the signals of the corresponding sensors even if the respective sensors are sensors incompatible with machines different from each other.
The sensor controller 110 converts the operational data received from the measurement sensor 130 into a standardized digital signal for transmission to the communication module 120. For example, the signals transmitted from the temperature sensor and the pressure sensor to the sensor controller 110 may be electrical signals of different formats from each other. When the electric signal is transmitted to the server 200 as it is, the server 200 cannot correctly recognize what information is contained. To this end, the sensor controller 110 can also perform the role of converting an analog signal or a digital signal into a standardized digital signal to be converted into a form that can be recognized by the server 200.
The communication module 120 transmits information between the sensor controller 110 and the server 200 or the user terminal 300. That is, the measured operation data is transmitted from the sensor controller 110 to the server 200, and information commanding the sensor controller 110 is received from the server 200 to be transmitted to the sensor controller 110.
The communication module 120 may preferably be a wireless communication module 120, but is not necessarily limited thereto, and may also be a wired communication module 120. In addition, the module 120 may be implemented to perform various communications such as 3G, 4G, WIFI, bluetooth, Zigbee, and the like.
The sensor controller 110, the communication module 120, and the measurement sensor 130 may be connected and fixed to each other by a connector 140. The connector 140 may also be implemented in the form of a wire or harness. Alternatively, the connector 140 may be implemented in the form of a plurality of pins formed at a region of each sensor. When implemented in the form of pins, the connectors 140 formed in the respective sensors are arranged and connected to be engaged with each other, so that the sensors can be connected to each other. Further, in the case where the connectors 140 are provided in such a manner as to be fixedly coupled to each other, not only the connection between the connectors 140 but also the position fixing effect between the sensors can be provided.
Further, referring to fig. 3 and 4, the sensor assembly 100 may further include a transducer 150.
The converter 150 performs digital/analog conversion or analog/digital conversion on the signal transmitted between the at least one measurement sensor 130 and the sensor controller 110. The converter 150 includes a digital/analog conversion section (DAC)152 and an analog/digital converter (ADC) 153. Further, the converter 150 may be connected to the measurement sensor 130 and the sensor controller 110 by a connection wire or a wiring, but may be configured in the form of a plurality of pins 151 as shown in fig. 4. In this case, a factory manager can easily connect the sensors by only an operation of simply inserting the converter 150 into the corresponding area, compared to wires or wiring.
The process by which sensor controller 110 collects operational data of machine 10 by measuring sensors 130 is described in detail below with reference to fig. 5.
First, the sensor controller 110 receives a sensing start command from the server 200 (step S110).
The sensor controller 110 confirms the sensing period (step S120). The sensor controller 110 may control to operate at a predetermined sensing period, but may reflect the sensing period change via a process of confirming the sensing period in advance when the sensing period changes. The sensing period refers to a period in which the sensing sensor 130 senses the operation data. When the operation data is continuously sensed for all times, this causes an overload to the sensing sensor 130 and power consumption is also excessive, so a specific period may be set and the operation data is sensed and collected only for the time.
The sensor controller 110 transmits a sensing start command to the measurement sensor 130 (step S130).
The measurement sensor 130 may receive the command and initialize the command (step S140).
Also, the measurement sensor 130 performs sensing at a sensing period (e.g., 1 second) delivered by the sensor controller 110 (step S150). The measurement sensor 130 may store data for a sensing period after performing initialization.
The measurement sensor 130 transmits the operation data measured at the sensing period to the sensor controller 110 (step S160).
The sensor controller 110 transmits the operation data to the communication module 120 to transmit the operation data to the server 200. At this time, the sensor controller 110 may transmit the operation data to the communication module 120 every time the operation data is collected, may accumulate the operation data at a period longer than the sensing period and transmit the accumulated operation data to the communication module 120, or may transmit the accumulated operation data when a request for the data accumulated therebetween is received from the server 200.
Further, the collection of operational data by the sensor controller 110 until the server 200 learns the measurements of the various machines may be accomplished in two embodiments.
Hereinafter, the following description will be specifically made with reference to fig. 6 and 7.
Fig. 6 is an embodiment when the server 200 is a cloud server existing outside the plant. That is, fig. 6 is an example of a case where plant management information is collected and managed in a cloud server outside the plant.
First, the user terminal 300 and the sensor assembly 100 are communicatively connected to each other through a local area network (e.g., bluetooth). At this time, information for identifying the sensor assembly 100 is provided on an application of the user terminal 300, and the user can set identification Information (ID) for the sensor assembly 100. The identification information of the sensor unit 100 includes identification information of the sensor controller 110 and identification information of the measurement sensor 130. Thereafter, if the measurement sensor 130 reads operation data of the machine and transmits an a/D signal value (i.e., an electrical signal value) including the operation data to the sensor controller 110, the sensor controller 110 transmits the a/D signal value and identification information of the sensor assembly 100 to the server 200. The server 200 detects the measured value corresponding to the a/D signal value with reference to a look-up table stored in advance. Also, the server 200 matches and stores the measured value as information for a specific machine of the user's factory with reference to the identification information of the sensor assembly 100.
Fig. 7 is a case where the server 200 is a server 200 using a network within a plant, instead of a cloud server. Preferably, the embodiment of fig. 7 is an embodiment implemented in a case where a cloud network environment is not supported, but is not necessarily limited thereto.
First, the sensor assembly 100 receives identification information of the sensor assembly set through the user terminal 300, as in the process of (r) of fig. 6. Thereafter, the user terminal 300 transmits the identification information of the sensor assembly 100 to the server 200, requests the firmware and the lookup table conforming to the sensor assembly 100, and receives the firmware and the lookup table. Next, the sensor controller 110 of the sensor assembly 100 downloads and installs the firmware and the lookup table from the user terminal 300. Accordingly, in case of receiving the a/D signal value from the measurement sensor 130, the sensor controller 110 may recognize the a/D signal value through firmware and extract the measurement value from the a/D signal value through the lookup table. Next, the sensor assembly 100 transmits the extracted measurement value to the server 200. The sensor controller 110 can download all firmware for the plurality of measurement sensors 130 and identify all a/D signal values. Further, in case of supporting a cloud network environment, the measured value stored in the server 200 may be transmitted to the cloud server again later.
As in the case of fig. 6, in the case where the firmware and the look-up table are not stored in the sensor assembly 100 but stored in the server 200, development of the firmware and setting work of the sensor assembly 100 can be minimized. In the case where firmware and a lookup table are loaded in the sensor controller 110, the capacity and performance of the MCU and the ROM of the sensor controller 110 are greatly affected. In this case, the development cost becomes considerably high. However, by the same method as fig. 6, the processing operation can be minimized, and the MCU of the sensor controller 110, the ROM manufacturing cost, or the work required for the operation can be reduced. Further, the sensor controller 110 performs only a role of transmitting an a/D signal, and thus can be connected with many measurement sensors 130, so that large compatibility can be ensured.
When the case of fig. 7 is applied to the same cloud network environment as that of fig. 6, since the firmware and the lookup table for many measurement sensors 130 are downloaded in one sensor controller 110, a/D signal values of many measurement sensors 130 can be recognized, and thus large compatibility can also be ensured.
Further, in the same manner as in fig. 7, when it is necessary to install firmware in the sensor controller 110, the firmware may be downloaded by automatically connecting to the server when a firmware installation or update event occurs.
Hereinafter, in the embodiment of fig. 7, the automatic firmware update process is specifically described.
A plant manager may approach the periphery of a specific machine while directly checking the appearance and interior of the machine or performing work such as traveling inside the plant.
At this time, the user terminal 300 held by the plant administrator can recognize the surrounding sensor module 100, and when sensing the sensor module 100 within a preset close range, can connect to the sensor module 100 by performing mutual wireless communication. For example, the connection may be made by various communication methods such as bluetooth, WiFi, ZigBee, and the like.
Next, the sensor controller 110 of the sensor assembly 100 may also transmit at least one of the identification information of the sensor controller 110 and the identification information of the measurement sensor 130 and the operation data of the measurement sensor 130 collected by the sensor controller 110 and the firmware information according to each measurement sensor 130 set in the sensor controller 110 to the user terminal 300. The firmware information may include version information of the corresponding firmware and identification information of the corresponding firmware and measurement sensor 130 information associated with the corresponding firmware.
The user terminal 300 transmits the firmware information to the server 200 while inquiring whether the firmware update is required.
The server 200 stores firmware information for each measurement sensor 130, and when the firmware information is updated, stores an update file.
The server 200 compares the version information of the firmware received from the user terminal 300 with the version information of the firmware currently stored in the server 200, and confirms that the firmware of the sensor controller 110 needs to be updated in the case where the level of the version information of the firmware received from the user terminal 300 is low.
Accordingly, information that needs to be updated is transmitted to the user terminal 300. In this case, the update may be performed automatically under the approval of the plant manager, or may be performed immediately without approval.
When performing the update, the server 200 may transmit a firmware update file, identification information of the sensor controller 110, and identification information of the measurement sensor 130 to the user terminal 300. The user terminal 300 identifies the sensor controller 110 to be updated with reference to the identification information of the sensor controller 110 and the measurement sensor 130, and transmits a firmware update file to the identified sensor controller 110 to enable installation.
As an additional embodiment, the update may also be performed by the following procedure.
First, the server 200 may transmit header data of firmware to be updated to the user terminal 300. The header data refers to data block No. 0 among data blocks constituting the firmware.
The sensor controller 110 or the user terminal 300 reads the entire data block number of the corresponding firmware based on the header data. Hereinafter, it is assumed that the number of entire data blocks is n (n is a natural number greater than 1).
Thereafter, the server 200 transmits data block No. 1 of the corresponding firmware to the user terminal 300, and the user terminal 300 transmits data block No. 1 to the sensor controller 110.
The sensor controller 110 or the user terminal 300 may also perform a Cyclic Redundancy Check (CRC) for data block number 1. CRC checks are also known as cyclic redundancy checks. Specifically, if the transmission target data is transmitted with a remainder value obtained by dividing the transmission target data by a check value specified in advance being added to the end of the transmission target data at the transmission end, the reception end compares the remainder value obtained by dividing the received data by the check value with the remainder value or determines whether the remainder value obtained by dividing the entire data transmitted with the remainder value added thereto is 0 to determine whether the data has an error.
When an error is detected, the sensor controller 110 may transmit a command to the user terminal 300 to request the server 200 for a data block in which the error has occurred again, or may transmit the command once again when the data block cannot be received by the request again or the error occurs again. If the number of re-requests exceeds a preset number, the sensor controller 110 or the user terminal 300 may transmit an error message to the server 200.
If no errors are detected, the sensor controller 110 copies the received data block for the corresponding measurement sensor 130 and appends the data block to an existing firmware block location stored in the memory of the sensor controller 110.
Also, it is confirmed whether the copied data block is the last data block.
If the copied data block is not the last data block, a process of receiving other data blocks is performed. Receiving data block No. 1 through data block No. n can be repeatedly performed in the same manner as this.
Finally, when the sensor controller 110 receives all the data blocks from the server 200, the sensor controller 110 may transmit a firmware download completion ack (acknowledgement) to the user terminal 300.
Since the firmware is automatically updated in the sensor controller 100 by such a procedure, the factory administrator performs firmware update for each measurement sensor 130 or places the installation file of the server 200 in the USB for update, so that it is not necessary to perform the work of installing the firmware to the measurement sensor 130.
In addition, the sensor controller 110 may be configured to include a memory storing a program (or an application program) for performing the above-described operations and a processor (e.g., a Micro Controller Unit (MCU)) for executing the above-described program.
In addition, only a part of the communication modules 120 of the plurality of sensor assemblies 110 include wireless communication functions based on 3G, 4G base stations, and the remaining communication modules 120 may also be configured to include only short-range wireless communication functions such as WIFI. With such a configuration, the communication cost using the communication network is reduced, and all data is collected in one area to be transmitted to the server 200, so that there is no big problem in the intelligent factory service utilization.
An embodiment of the present invention can also be implemented in the form of a recording medium (e.g., program modules executed by a computer) including computer-executable instructions. Computer readable media can be any available media that can be accessed by the computer and includes both volatile and nonvolatile media, removable and non-removable media. Also, computer readable media may include computer storage media and communication media. Computer storage media includes volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules or other data. Communication media typically embodies computer readable instructions, data structures, program modules, other data in a modulated data signal such as a carrier wave or other transport mechanism and includes any information delivery media.
The method and system of the present invention have been described in connection with particular embodiments, and some or all of its structural elements or operations may be implemented using a computer system having a general-purpose hardware architecture.
The foregoing description of the present invention is merely exemplary, and it will be understood by those skilled in the art to which the present invention pertains that the present invention can be easily modified into other specific forms without changing the technical spirit or essential technical features of the present invention. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. For example, the respective components described as a single type may be dispersed and implemented, and similarly, the components described as a dispersed type may be combined and implemented.
The scope of the present invention is defined more by the appended claims rather than the detailed description, and the meaning and scope of the claims and all changes and modifications derived from the equivalent concept thereof should be construed as falling within the scope of the present invention.
