Description

Remote monitoring system and method

The present invention relates to a remote monitoring system and method, and more particularly, to a monitoring unit that receives a control parameter for a plurality of facilities and executes a control, a mobile communication device remotely connected through a floating IP wireless Internet with low cost and high efficiency. The present invention relates to a system and a method for enabling report reception and control.

In general, for electrical installations, safety management is required to prevent failures or accidents in advance, and to minimize the expansion even in the event of a failure. The safety management of electrical equipment is basically carried out by the safety manager in charge of the electrical equipment.

For large electric equipment consumers (capacity of 5000KW or more), a central computer (large database server) of the central control room on the Internet is constructed, and a monitoring unit for data extraction is attached to each electrical facility in the premises, and the central computer and The method of transmitting and receiving data using a communication cable (RS232 or RS485 standard) between each monitoring unit is mainly used. In this case, since a large number of safety managers generally reside in the central control room and each electric facility such as a substation room for management, the continuous management of the ordinary time and the rapid response in the event of a failure are possible, thereby ensuring safety and reliability.

On the other hand, more than one safety manager is required to manage the medium-sized electrical equipment customer (less than 5000KW and 1000KW or more), but it is not possible to stay in a 24-hour electrical facility such as a substation room. Since the work is carried out in combination with the task, not only continuous management but also judgment and countermeasures in case of a failure may be impossible, resulting in low safety and reliability.

Furthermore, in the case of a small electric equipment customer (less than 1000KW capacity), electric safety management can be entrusted to an external agency, and in general, one safety manager belonging to the external agency is responsible for a large number of consumers. You will manage them in a circuit. Therefore, as well as continuous management of the peace of mind, it is extremely difficult to quickly recover in the event of a failure, it is almost impossible to secure stability and reliability.

Here, the safety inspection of the electrical equipment by the personnel of the safety manager is performed in the power failure state in which the electric power was cut off. In the inspection work, the safety manager, who is in charge, checks all conditions such as voltage, current, and overheating by hand. Therefore, a lot of time and money was generated as manpower was put into the inspection work, and in particular, there was a problem that the risk of safety accidents due to unexpected power supply or residual charges existed.

Thus, in order to solve various problems such as high cost, inconvenience, and safety of work by such personnel, an automated monitoring device is already being developed and operated. As an example, the measurement of the customer's electrical equipment is received by a monitoring unit installed in the electrical equipment, and when it is determined that the electrical equipment is disturbed by comparison with the set value, the modem is sent to a central computer in a remote central control room via a modem. Applicants' remote electric monitoring method (Patent No. 0336320, Patent No. 0396394) registered in the method of notifying the safety manager, the person in charge of the electrical equipment is analyzed and known is known.

In the above prior art, fault reports and fault data from a plurality of monitoring units are accumulated in a large database server constituting a remote central computer via a modem via the modem. The security manager is connected to the central computer to receive the data and confirm the data.

However, in the related art, since the construction, management, and use costs of the large database server constituting the central computer are considerable, ranging from millions of won to tens of millions of won, the installation, adoption, and operation of a remote monitoring device for small and medium-sized electric facility customers This was difficult. In addition, since a plurality of monitoring units are connected to the server, a communication bottleneck occurs in a concentrated time zone, resulting in poor or unresponsiveness. In the event of a failure of the server itself, which has both an analysis and a communication function, the safety manager cannot know whether or not the electric equipment is in charge.

In addition, the fixed IP cost for communication between each monitoring unit and the central computer caused a large cost in proportion to the number of installation of the monitoring unit. In addition, in terms of data traffic, since fault data is transmitted from each monitoring unit to the central computer, and almost the same amount of data must be transmitted from the central computer to each person's personal computer, it causes a lot of waste of bandwidth. .

If the person in charge does not have a personal computer at a place other than the central control room where the central computer is installed, the person in charge can only recognize a brief failure notice notified from the central computer, and confirm the exact state and data of the failure. It was impossible to do.

The present invention is to provide a remote monitoring system and a method for reducing cost and high reliability by directly reducing the communication path and the bandwidth of the mobile communication device.

In addition, by establishing a one-to-many connection, a large database server connected to multiple monitoring units eliminates bottlenecks, resulting in zero construction, management and use costs, and bottlenecks. The purpose of the present invention is to provide an integrated remote monitoring system and method for realizing cost reduction and quick response by allowing a device to be connected in a one-to-one connection.

<Basic configuration-relay of floating IP>

In the remote monitoring system of the present invention, the monitoring unit 100 and the mobile communication device 40 are basically connected to each other, and configured to perform data communication through the wireless Internet.

The input terminal 11 of the monitoring unit 100 is connected to one or more facilities a1, a2, ..., an that are to be monitored. The facilities a1, a2, ..., an are, for example, various equipments such as transformers, generators, batteries, power receivers, and power distribution lines provided in the electric consumer.

All faults such as phase loss, power failure, over current, short circuit, overheat, generator battery abnormality, external device abnormality, etc. generated in the above facilities (a1, a2, ..., an) are subject to normal management, and recovery in case of failure (B) they are subject to preventive measures to prevent damage spread. Accordingly, the measurement values of one or more various monitoring parameters capable of confirming the failure of the facility are detected by the monitoring parameter detecting means , which are not shown, and are received and input to the input terminal 11 of the monitoring unit 100. Examples of the monitoring parameters include voltage, current, leakage current, temperature, battery voltage, electrical parameters of other external devices, and the like. The measured value of the monitoring parameter input to the input terminal 11 is digitized via the A / D converter 12 and is immediately stored in the short-term storage unit 15 by the data control unit 10 (S12). However, when a predetermined long-term storage period arrives (S13), the measured values collected during that time are moved and stored in the long-term storage unit 16 by the data control unit 10 at once.

The data control unit 10 is configured on the basis of a central processing unit (CPU), controls the input and output to the equipment (a1, a2, ..., an), and serves to store the input measurement value The control unit. The control operation of the data control unit 10 is processed by a built-in program.

Measurement values of one or more monitoring parameters stored in the long-term storage unit 16 are received by the mobile communication device 40 remotely connected to the wireless Internet. The mobile communication device 40 is, for example, an information terminal capable of wireless internet information communication such as a smartphone, a tablet PC, a notebook computer, a PDA, a mobile phone, and the like.

The monitoring unit 100 includes a communication means 23 and an information processing control unit 20 .

The communication means 23 is a wireless Internet connection means using a floating IP. For example, it is a wireless internet module embedded in a smart phone or the like.

The information processing control unit 20 communicates the communication means 23 to notify the information relay 30 on the wireless Internet every time the IP address change assigned to the monitoring unit 100 changes or every predetermined IP address notification period. ) Is a control unit for controlling. The information processing control unit 20 is configured based on the central processing unit (CPU). However, although the data control unit 10 and the information processing control unit 20 may be implemented by a central processing unit (CPU), the centers are separated from each other in terms of processing speed or stability in terms of reliable separation driving. It is preferably implemented by a processing unit (CPU). The control operation of the information processing control unit 20 is processed by a built-in program, and the control program needs to perform relatively various operations, so that it is stored in the program unit 21 of the memory, loaded and used, and will be described later. The control command from the device 40 may be configured to be upgradeable at any time.

The information repeater 30 includes an IP database 37 and an IP. The relay unit 32 is provided.

The IP database 37 is a database that stores IP addresses of the monitoring units. As the configuration field, for example, the identifier of the monitoring unit and the current IP address of the monitoring unit are required fields.

The IP relay unit 32 updates the IP database 37 with a new IP address notified from the monitoring unit 100, and the IP database (3) in response to an IP address query from the mobile communication device 40. 37) Inquiry module. The IP relay unit 32 is based on a database processing program, but does not perform any load-intensive tasks such as analysis or statistical processing, and simply receives and stores IP addresses from predetermined monitoring units 100. The task differs from the conventional central computer in that it can be implemented with extremely simple software because it only performs the task and responds to the IP address inquiry from the predetermined mobile communication devices 40.

The mobile communication device 40 includes an IP obtaining means (not shown ) , a measuring value obtaining means (not shown ) , and an analysis display means 42 . They may each be implemented by software means (modules), and they may be integrated into one.

The IP obtaining means is a means for querying and receiving the information relay 30 on the IP address of the monitoring unit 100 to which the mobile communication device 40 is to be remotely connected.

The measured value obtaining means is a means for receiving the measured values of the facilities a1, a2, ..., an by accessing the monitoring unit 100 with the obtained IP address.

The analysis display means 42 is a means for analyzing the received measured value and displaying it on a screen or by voice.

Using the system (apparatus) of the present invention configured as described above, the remote communication device 40 is connected to the monitoring unit 100 to receive the measured values of the facilities a1, a2, ..., an. The method is as follows.

In the remote monitoring method of the present invention, the measurement value of the monitoring parameter from the facilities (a1, a2, ..., an) in which the data control unit 10 of the monitoring unit 100 is connected to the input terminal 11 (S11). It is based on the configuration of receiving and short-term storage (S12) and periodic long-term storage (S13, S13a). Then, in order for the mobile communication device 40 remotely connected to the wireless Internet to receive the measured values stored in the monitoring unit 100 using the floating IP wireless Internet, an IP address notification step ( S23 , S23a ) and IP address storing step (S31, S31a) and, IP address acquiring step (S43, S33, S33a, S33b), and the measurement value acquiring step (S44, S44a, S24, S24a), characterized in that it comprises an analysis display step (S44b) It is done.

The IP address notification step ( S23 , S23a ) , the monitoring unit 100, the information relay 30 on the wireless Internet for each IP address change or predetermined IP address notification period of the wireless Internet floating IP, To be notified. The predetermined IP address notification period may be set to 10 minutes, for example. Then, basically every 10 minutes, the IP address is notified from the monitoring unit 100 to the information relay 30. However, the communication traffic every 10 minutes is also heavy. In this case, the configuration for setting the predetermined IP address notification period is eliminated, and when the monitoring unit 100 detects that its own IP address has changed, the IP address is immediately transmitted from the monitoring unit 100 to the information relay ( It is more preferable to notify 30.

The IP address storing step ( S31 , S31a ) is, the information repeater 30, the step of storing the IP address of the monitoring unit (100). By storing the IP address, the IP address can be inquired later when the IP address inquiry request from the mobile communication device 40 is made.

The IP address acquisition step (S43, S33, S33a, S33b) is a step of the mobile communication device 40 is, by querying the IP address of the remote connection and the monitoring unit 100 to the data repeater 30 receives . Thus, even if the monitoring unit 100 is configured to use the inexpensive floating IP wireless Internet, since the IP address of the monitoring unit 100 is always updated in the information repeater 30, the mobile communication The device 40 may obtain the current IP address of the monitoring unit 100.

The measured value acquisition step (S44, S44a, S24, S24a), the mobile communication device 40 has the facility to connect the monitoring unit 100 to the acquired IP address (a1, a2, ..., an ) Is a step of receiving a measurement of. The measurement value received by the mobile communication device 40 is data stored in the short-term storage unit 15 or the long-term storage unit 16 by the data control unit 10 of the monitoring unit 100. For the analysis and statistical processing in the mobile communication device 40, not only the data of the equipment (a1, a2, ..., an) that caused the failure, but also the equipment (a1, a2, ..., which is operating normally). You may also need an) data. Therefore, it is desirable to be able to receive all kinds of stored data, whether or not there is a failure.

The analysis display step S44b is a step in which the mobile communication device 40 analyzes and displays the received measurement. Thus, the person in charge is a situation such as whether the equipment (a1, a2, ..., an) connected to which monitoring unit 100 has a failure or normal operation through the analysis result displayed on the screen of the mobile communication device Can be identified and appropriate action can be taken accordingly.

In addition to the basic configuration as described above, the system of the present invention can have the following extended configuration.

<Plural facilities>

The present invention can also be applied to a plurality of facilities (a1, a2, ..., an) connected to one monitoring unit 100. In this case, the input terminal 11 may be configured as a switching input terminal which is connected to the monitoring parameter detection means provided in the equipment (a1, a2, ..., an), respectively. And, a switching control section for data to the data control unit 10, controls the switching of the switching input end, the input end of the plurality of the equipment (11) (a1, a2, ..., an) successively connected in rotation It may be comprised.

According to this configuration, when a monitoring parameter is received from the facilities a1, a2, ..., an to the monitoring unit 100, a plurality of facilities (a1, a2, ..., an) to be monitored are received. The data control unit 10 sequentially connects the input terminal 11 to the monitoring parameter detecting means provided at each. That is, under the control of the data control unit 10, the input terminal 11 is first switched to the facility a1 to establish an electrical connection S11, and receive various parameters S12. Upon completion, the input terminal 11 is switched to the next facility a2 by the control of the data control unit 10 (S15) to establish an electrical connection (S11), and receive various parameters (S12). Proceeding in this manner, when the reception of the parameters of the facility an (S12) is completed, the input terminal 11 is first switched back to the facility a1 by the control of the data control unit 10 (S15) and is switched to the electrical connection (S11). Is established and receipt of various parameters (S12) is performed. Repeat this cycle. Thereby, many facilities a1, a2, ..., an can be managed and monitored by one monitoring unit 100.

<Relay of fault notification except data>

In the prior art, a problem was that a large amount of traffic was consumed by transmitting data from a monitoring unit to a central computer at a remote location. In contrast, in the present invention, data is not transmitted, and only the fact that a failure occurs is notified to the information repeater 30 from the monitoring unit 100, and the information repeater 30 sends the information to the mobile communication device 40. In the mobile communication device 40, the IP address is queried to the information repeater 30 as described above, connected to the monitoring unit 100 that reported the failure, and received data one-to-one. It was set as the structure.

To this end, the information processing control unit 20 has a failure determination unit and a failure notification unit . These may be implemented by a control program stored in the program storage unit 21.

The fault judging unit is a module for comparing the measured values from the respective facilities a1, a2, ..., an with the set values stored in the setting value storage unit 22 in advance to determine whether or not the facilities are faulty.

The failure reporting unit is a module for transmitting a failure notification to the information repeater 30 when it is determined that a failure occurs. The determination of the failure occurs when the measured value is out of the normal range of the set value.

The information repeater 30 includes a failure database 39 , a responsible database 38, and a reception report unit 33 .

The failure database 39 is a database that stores an identifier of the monitoring unit that has sent the failure notification. As the configuration field, an identifier of the monitoring unit and a flag of presence or absence of a fault report are mandatory. However, the failure database 39 may be integrated into the IP database 37 and configured as one field.

The responsible database 38 is a database for storing mobile communication device information of the person in charge of each monitoring unit. As the configuration field, the identifier of the monitoring unit and the connection information of the mobile communication device of the person in charge is essential. Here, the connection information of the mobile communication device may be, for example, a telephone number or an IP address. However, the responsible database 38 may be integrated into the IP database 37 and configured as one field.

The reception report unit 33 receives the failure notification to the mobile communication device 40 of the person in charge of the monitoring unit 100 that has sent the failure notification through the inquiry of the responsible database 38. This module sends a report. In the reception report, for example, when a telephone number is used, an ACS (Auto Calling System) may be used to transmit a voice message stored in advance, and a SMS (Short Message Service) system may be used. Text messages can be sent, or they can be performed together. Alternatively, for example, when using an IP address, a message may be transmitted using a messenger system.

When using this configuration, the IP relay unit 32, if the IP address of the monitoring unit 100 that sent the fault notification from the mobile communication device 40 is requested, the fault database 39 and the IP It is preferable to specify the IP address by querying the database 37. Of course, if these databases are integrated, they can be retrieved from one integrated database.

In addition, according to the above configuration, the monitoring unit 100, the failure determination step of determining whether or not the failure of the equipment (a1, a2, ..., an) by comparing the measured value with a previously stored set value, In the case where a determination occurs, the monitoring unit 100 transmits a failure notification to the information relay 30, and the monitoring unit 100 sends the failure notification to the information relay 30. ), And the reception report step of transmitting the reception report of the failure notification to the mobile communication device 40 of the person in charge of the monitoring unit 100 that sent the failure notification. Thus, unlike the prior art, since it is directly determined whether the monitoring unit 100 collects data, not a remote database server, the traffic is reduced, the database construction, maintenance, operating costs are reduced, and the failure notification is also said Since it is not sent directly to the mobile communication device 40 but is stored in the intermediate relay information relay 30, the IP address of the monitoring unit 100 is always available when the mobile communication device 40 becomes available. After the mobile communication device 40 directly connects to the monitoring unit 100, the actual data is received, so that the timing of the traffic can be adjusted.

<Remote Control>

On the other hand, in order to recover from a failure or to change other functions, a drive signal for instructing the operation of a controlled part of a facility (a1, a2, ..., an) connected to the monitoring unit, for example, a switch, a light, a motor, or the like. There may be times when you need to send remotely. The configuration for this purpose will be described.

To this end, the data control unit 10 includes an output terminal 13 for outputting a drive signal to a controlled unit (not shown) provided in the facilities a1, a2, ..., an. However, when the control unit is operated with an analog signal, the control unit may further include a D / A converter 14 to output the driving signal. In addition, the mobile communication device 40 includes a command module 44 for transmitting a control command for generating the drive signal to the monitoring unit 100.

Thus, the data is transmitted from the mobile communication device 40 (S46, S46a) to the data control unit 10 via the information processing control unit 20 (S26, S26a).

According to this configuration, the mobile communication device (S46, S46a) is, the monitoring unit (100 a control command for generating a driving signal for driving the blood controller provided in the equipment transmitting the monitoring unit 100, and In response to the control command, the information processing control unit 20 generates a driving signal for driving the controlled unit, and transmits the driving signal to the data control unit 10. The data control unit 10 transmits the driving signal to an output terminal . By sending, the command step of controlling the controlled unit (not shown) provided in the equipment (a1, a2, ..., an) connected to the output terminal.

As a result, the mobile communication device 40 can control the operation of the facilities a1, a2, ..., an.

<Registration function of monitoring unit>

On the other hand, there is a case where the mobile communication device 40 needs to perform management such as new registration, change, disposal registration, etc. of the monitoring unit 100. The configuration for this will be described.

To this end, the mobile communication device 40 preferably comprises a unit database 49 and a registration module 41 .

The unit database 49 is a database that stores information of the monitoring unit 100 in charge of the owner of the mobile communication device 40. As the information of the monitoring unit 100, for example, the name of the monitoring unit, the installation position, the number and name, the type of equipment to be managed. However, the unit database 49 is not necessarily provided in the mobile communication device 40, but is integrated and constructed in the IP database 37 or the responsible database 38 in the information repeater 30, for example. It may be.

The registration module 41 is a module which newly registers , changes, or discards information about the monitoring unit 100 that is newly added, changed, or discarded in the IP database 37 and the unit database 49.

At this time, the mobile communication device 40, the registration step of registering new, changed, discarded information on the information relay 30 and the mobile communication device 40 with respect to the newly added, changed, discarded monitoring unit 100 Will be able to perform

<Change set value>

The mobile communication device 40 controls to change the set value which is a criterion for determining whether or not a failure occurs when a specification change or other reason of the facilities a1, a2, ..., an occurs. It is preferable to have a set value change module 43 for sending a command to the monitoring unit 100.

Then, the mobile communication device 40 performs a set value changing step of transmitting a control command for changing the set value to the monitoring unit 100.

Thus, the information processing control unit 20 of the monitoring unit 100 performs the control command to change the setting value stored in the setting value storage unit 22 to a new value.

As mentioned above, although this invention was demonstrated according to the specific Example, this invention is not limited to this Example, Equivalent change, modification, and improvement which were made within the range of a claim are all included in the scope of the present invention. Should be interpreted.

The present invention can be applied to a remote monitoring system and method capable of remotely performing measurement values, fault occurrence facts, and facility control by a mobile communication terminal located remotely from a facility to be monitored, managed, and controlled.
