And does not mean that the technical idea and scope of the present invention are limited.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an overall configuration of a remote control system of a cold-type facility in a store in a chain according to an embodiment of the present invention; FIG.

As shown in FIG. 1, the remote control system of a cold-type facility in a store in the form of a chain according to an embodiment of the present invention includes a chain store type store Temperature equipment 400 provided with one or more sensors 410 for sensing the operation state and temperature in real time and temperature data from the sensor 410 of the cooling and heating equipment 400 A receiver 200 for wirelessly receiving temperature data sensed by the sensor 410 of the cold / hot facility 400 from the transmitter 300 via RF, And a web server 100 that receives data via the Internet. Through these, it is possible to diagnose and predict an abnormality or failure of each of the cold / hot facilities 400 in the store, It can be quickly processed or prevented from being broken down, and can be efficiently processed by linking with the A / S company in case of failure diagnosis.

In the system according to the embodiment of the present invention, there are a plurality of stores in the form of a chain, and a plurality of cold / hot facilities 400 are provided in stores (b11, 12, ..., bmn) One or more sensors 410 (S1, S2, S3, ..., Sn) for detecting the operating state and temperature in real time are provided for each facility 400.

The sensor 410 may be installed and operated in various forms such as temperature, current, voltage, electric power, pressure, etc., in accordance with the purpose. In the embodiment of the present invention, a sensor for sensing temperature is installed and operated . The sensor 410 installed in the cold / hot facility 400 is connected to the transmitter 300 by wire, and the temperature data sensed by the sensor 410 is transmitted to the transmitter 300.

2 is a block diagram showing a configuration of a transmitter in the system of FIG.

As shown in FIG. 2, each transmitter 300 includes a sensor-specific data collecting module 310, a sensor data calculating module 320, A data compression storage module 330, a sensor-specific ID assignment module 340, a wireless data transmission / reception module 350, and a radio frequency automatic switching module 360.

The temperature data of each sensor 410 transmitted to the transmitter 300 is collected for each sensor 410 in the sensor-specific data collecting module 310 and is calculated as a value formatted by the sensor data computing module 320 .

Here, the formalized value means that the characteristics of each sensor in the sensor manufacturer are documented so that the user who uses the sensor can use it as a reference.

In the embodiment of the present invention, the values obtained by installing and comparing the actual cooling / heating equipment based on the reference data as described above are used as basic data and are already assigned to the web server 100.

The data calculated by the sensor data calculation module 320 is compressed and stored in the internal memory in the data compression / storage module 330 to facilitate transmission.

The sensor 410 installed in one or more of the cold / hot facilities 400 is given an ID by the sensor-specific ID module 340 and serves as an ID instead of the location or model name of the hot / cold facility .

The per-sensor ID assigning module 340 determines whether or not the chain store manager has detected abnormality or failure in any of the cold / hot facilities in connection with the fact that the same or similar cold / Not only the means for clearly distinguishing but also the data used to dataize and share the detection results of sensors appearing in respective cold / hot facilities and to manage the history of cold / hot facilities.

That is, in the case where a plurality of cold / hot facilities of the same kind are installed in a store, since it may be difficult to easily identify which cold / hot facility is experiencing an abnormality, an ID is assigned to each sensor, So that the A / S center 700 can easily perform a repair when the A / S staff tries to repair the trouble, or if the trouble occurs in the cold / hot facility or when the trouble is requested from the customer center 500.

Also, the ID assignment may be useful when the location of the cold / hot equipment to which the sensor 410 is attached is difficult to access easily by a roof, a verandah, etc., or when access is difficult due to fire or cold.

The sensor data collected and stored according to the ID thus provided is standardized for wireless transmission in the wireless data transmission / reception module 350 and transmitted to the receiver 200 through RF wireless. Here, the RF can apply the short-range wireless communication standard conforming to the IEEE802.15.4 standard. Since the transmitter 300 can exchange data with the receiver 200 in both directions and is a standardized communication method, another chain store manager can use the same or near frequency in the same short distance wireless communication method, .

In the system according to the embodiment of the present invention, an individual ID is assigned to each terminal of the transmitter 300 and the receiver 200 within a range that does not deviate from the standardized communication method, and a wireless transmission / Protocol is adopted separately.

In addition, since a frequency conflict may occur with other chain store managers at the same or adjacent frequency in use in the embodiment of the present invention, a radio frequency automatic switching module 360 is provided.

3 is a block diagram showing a configuration of a receiver in the system of FIG.

In the system according to the embodiment of the present invention, a receiver 200 is provided. At least one receiver 200 is installed in each store. If the receiver 200 has a large area and many cooling / heating facilities 400, The receiver 200 collects all sensor data received from the server 300 and transmits the collected data to the web server 100 via the Internet. As shown in FIG. 3, the receiver 200 includes a data collection time management module 210, A data compression storage module 220, a radio frequency automatic switching module 230, a wired communication module 240, and a cold / hot facility abnormality notification module 250.

The temperature data of each sensor 410 wirelessly transmitted from the transmitter 300 via the RF is collected by the data collection time management module 210 and stored in the data compression storage module 220 so as to facilitate the transfer of the collected data And stored in an internal memory.

Each receiver 200 is given a separate ID, which allows comparison with the minimum store manager information for that store. Herein, the minimum store manager information of the store is basic information such as a store name, an address, a contact address, and the like. This information is used to alert a cold shop 400 if it is abnormal, And is used as one of communication means for responding to the request. And is used as data for managing and sharing the history of the cold / hot facility 400.

The radio frequency automatic switching module 230 transmits and receives bi-directional radio frequency automatic switching module 360 of the transmitter 300 and frequency collision can not be avoided in a device using RF, How to identify when the same or adjacent frequency occurs, and how to avoid the identified frequency if there is a possibility of collision.

FIG. 4 is a flowchart illustrating the automatic frequency switching of the transmitter and the receiver of FIG. 2 and FIG. 3;

The receiver 200 operates normally while collecting data by utilizing the frequency with which the transmitter 300 communicates with the transmitter 300 for a certain period of time (S401)

At this time, adjacent frequencies where the same or crosstalk may occur are searched together (S402). If they are not the same or adjacent frequencies, data is ignored (S403) and the process returns to the step S402.

In step S404, it is determined whether data collected on the same or adjacent frequency is transmitted to the transmitter 300 in a predetermined communication method. If the data is determined to be a predetermined communication method, data is updated normally in step S405 and the process returns to step S402.

If the communication method is not the predetermined communication method, it is determined that there is a frequency collision due to the non-transmitter 300 defined in the embodiment of the present invention (S406), and the information and the quantity of the transmitter 300 to transmit the data are grasped. (S407)

Also, the adjacent frequency that will not collide is confirmed by a similar method, and a stable frequency free from the possibility of collision is secured (S408)

Then, the transmitter 300 is instructed to change to a stable frequency in step S409, and the transmitter 300 is communicated with the changed frequency in step S410. In step S411, If the information and the quantity are correct, the data is updated normally (S412) and the process returns to step S402.

Meanwhile, in order to prevent all transmitters 300 from performing a frequency change command at one time due to a frequency collision, the receiver 200 does not remove the existing frequency until the number of transmitters 300 coincided with a predetermined number of transmitters 300, And transmits the frequency change command to the transmitter 300. When all the transmitters 300 have completed the command,

Then, the transmitter 300 is checked (S414). If the number of transmitters is correct, the data is updated normally (S415) and the process returns to step S402. If the number of transmitters is not correct, the process returns to step S413.

The compressed and stored temperature data is then transmitted from the wired communication module 240 to the web server 100 via the Internet.

In this case, the wired communication protocol is applied within a range that does not deviate from the basic form in the data transmission format, thereby preventing collision with the similar data format of other system and minimizing transmission errors by reducing errors.

In addition, when a failure or abnormality of the cold / hot facility 400 is detected based on the compressed and stored temperature data received from the web server 100, the chain store manager notifies the cold / Or notify that an error has occurred by sound.

5 is a block diagram showing a configuration of a Web server in the system of FIG.

A system according to an embodiment of the present invention includes a web server 100. The web server 100 operates on a computer and includes a data storage DB 110, a web page 120, A data operation module 140, a failure diagnosis prediction module 150, a customer center automatic notification module 160, and an SMS notification module 170. [

The data storage DB 110 stores the data obtained from each sensor in the store by the cold / hot facility, transmitter, and receiver and stores the data in real time. Also, data of temperature changes and inflection points of normal operation are set and stored in advance as a criterion for determining abnormality of cold / hot equipment and basic diagnosis diagnosis prediction. In addition, the sensor data stored in real time is bridged with the normal operation data, and abnormal data classified by type such as simple abnormality or failure is also stored.

In addition, the web server 100 operates the web page 120 so that the stored information can be clearly displayed, managed, and maintained.

In the web page 120, it is possible to register separately for each chain company requesting the management of the cold / hot facility 400, and it is possible to register and manage each store separately by ID.

By providing an ID for each store, the store manager information module 130 can secure and manage the minimum store manager information that indicates basic information such as a store name, an address, and a contact address, And informs the chain store manager of the failure status so that the cold / cold storage facility 400 can take measures. And is used as data for managing and sharing the history of the cold / hot facility 400.

Also, the web server 100 compares the data extracted by the data operation module 140, which includes an operation algorithm for determining whether the value is equal to or higher than a predetermined value, to determine an abnormality of the cold / And a failure diagnosis prediction module 150 for determining whether the failure is normal or abnormal.

6 is a flowchart showing the operation of the fault diagnosis prediction module of the web server of FIG.

First, each sensor 410 of the cold / hot facility 400 senses the temperature and normally operates while transmitting the data (S601)

Then, normal operation data stored in advance in the data storage DB 110 is compared with data transmitted from each sensor 410. (S602)

7 is a diagram showing an example of normal operation of the cold / hot equipment in the system of FIG.

The failure diagnosis prediction module 150 shows some examples in FIG. 7, in which the basic failure diagnosis prediction standard data the temperature changes and inflection points of normal operation.

As shown in FIG. 7, the general refrigeration equipment sets the temperature at the upper limit value (T2) and the lower limit value (T1) in order to maintain the contents for a long period of time while preventing damage to the contents, In case of stopping the operation, when it reaches the upper limit value (T2), it repeats the cycle of t1 and t2 so as to operate again.

In this case, in order to maintain a stable temperature of the refrigeration equipment, the defrosting function is performed according to the season or the surrounding environment, and a third temperature (T3) may appear as in the case of overlapping the defrost sections. The operating range. Here, the heating facilities operate in reverse.

In this case, the normal operation of the cold / hot equipment is compared with the data transmitted from each sensor (S602)

In step S603, the data is updated in step S603. In step S604, the process returns to step S602. If not, the sensor data is compared with the abnormal data to classify the sensor data as simple abnormality or failure.

Here, the sensor data stored in real time are compared with the temperature change data pattern during the normal operation of the cold / hot equipment and the received temperature change data, and the patterns are compared. If they do not coincide with each other, And stored in the data storage DB 110 continuously.

In the case of a simple abnormality, the abnormality symptom is recovered, and in the case of a failure, the abnormality symptom pattern is compared with the abnormal data stored in the data storage DB 110, so that the accuracy of judgment can be improved.

8 is a diagram showing an abnormal operation example of the cold / hot equipment in the system of FIG.

Generally, the cold / hot facility is indicated as abnormal temperature due to malfunction of the function or aging of parts, or when the customer can not close the door properly during the purchase of the goods.

In addition, if the cold / hot facility stops temporarily due to power failure, or if the defrost becomes longer than the set time due to the defrost due to temperature change, there is no abnormality in the facility due to fire in the store, Abnormal symptoms such as when the abnormal symptoms or symptoms will appear.

For example, when the refrigerating apparatus is operated at a temperature set at the upper limit value T2 and the lower limit value T1 and stops at the lower limit value T1 and then reaches the upper limit value T2, , It is judged that the operation is abnormal when the period is extended to t1 ', t2' or when the period does not reach the lower limit value (T1) as t1 '.

Also, even when the temperature set by the upper limit value T2 and the lower limit value T1 is exceeded as T4 and T5, it is judged that the operation is abnormal.

If this phenomenon persists, the contents of the cold / hot equipment will be damaged and the customer will lose trust, and the chain store manager will have to pay for the normal operation of the cold and hot equipment together with the massive loss of goods.

Accordingly, it is difficult to immediately recognize the failure symptom of the conventional cold / hot equipment, and the equipment abnormality can be recognized only when the operation of the equipment is stopped or the performance is suddenly decreased. If it is determined that the cool / Is stored as error information (S606), and the chain store manager can find out as soon as possible so that it can be solved. When the chain store manager recognizes an error or a failure, the web server 100 notifies the chain store manager in some form .

First, the customer center automatically notifies the customer center 500 through the customer center automatic notification module 160 that the chain store manager can make a greater loss by determining and repairing the fault as well as the loss of the product due to the abnormal symptom or symptom before the fault Prevent it from happening.

9 is a flowchart illustrating an operation of the customer center automatic notification module in the web server of FIG.

If it is determined that the sensor data transmitted due to an abnormality or a fault in the cold / hot facility is abnormal, the error information of the web server 100 including the abnormal state of the hot / cold facility and the manager information of the chain store where the hot / (Step S901). In step S901, the customer center 500 obtains the web page 120,

The customer center 500 monitors the error information (S902) and notifies the chain store manager 600 of the cold / hot equipment of the symptoms of the cold / hot equipment (S903).

In S904, if it is more than simple, the abnormal situation is terminated and the error of the customer center 500 is canceled (S905). Then, the web server 100 judges whether the fault is simple or abnormal from the chain store manager 600, (S906)

In the case of a failure or a possibility of failure, the chain store manager 600 confirms whether or not the cooling / heating equipment has been repaired and, upon approval, connects to the A / S center 700 to dispatch the A /

Finally, the history is stored in the web server 100 (S908)

If the web server 100 detects an abnormality such as an abnormality or a malfunction, the abnormal state is informed to the chain store manager through the SMS notification module 170 according to the pre-contract, The controller 200 may notify the controller 600 of an error or notify that an error has occurred by sounding through the cold / hot fixation error notification module 250 of the receiver 200. [

On the other hand, if the data collected in the web server 100 is shared by the chain head office to manage the state and abnormality of each store and the cold / hot equipment and manage the history, it may be linked with the POS 600 of the chain store .
