Description

Automatic transfer system having self diagnosis function

The present invention relates to an automatic power transfer system (ATS), and more particularly, to a power automatic transfer system capable of self-diagnosis and a management server system for remotely managing and controlling the system.

If an abnormal situation occurs due to an overload or a fire during use of the electrical load, the power supplied to the load is automatically cut off and a power failure state occurs. For example, sudden power outages in fish farms, aquariums, hospitals, and special crop farmers can result in life and property damage. In order to prevent this, the uninterruptible power supply system (UPS) is provided and used as a buffer. Typically, a UPS usually consists of a rectifier, an inverter, and a battery charger. Cost-efficient ATSs are widely used because these UPSs require separate storage spaces to maintain constant temperature and humidity, as well as high battery maintenance costs.

ATS (Automatic Transfer System) refers to a device or system that supplies power to a load by automatically operating a generator when commercial power or other power is suddenly interrupted and power supply to the load is interrupted. Normally, the power failure time until the generator starts and the power supply is within 1 minute, and if the commercial power is supplied again, the commercial power is supplied to the load instead of the power supplied to the load, and the driving of the generator is stopped.

In this ATS system, it is important to check the condition of the generator in advance and manage it for normal operation. However, the general ATS system does not have a function of self-diagnosing the state of the generator and automatically notifying the administrator of the current state of the generator or automatically diagnosing the state of the generator.

Hereinafter, the self-diagnostic function of the various ATSs 100, 200, and 300 will be described in detail with reference to FIGS. 2 and 3.

2 is a block diagram of a self-diagnostic type ATS according to an embodiment of the present invention in FIG. 1, and FIG. 3 is a block diagram of the ATS controller 130 in FIG. 2.

As shown in FIG. 2, the self-diagnostic type ATS 100 according to an embodiment of the present invention also senses input power to supply any load by selecting any one of commercial power input and emergency power generated by the generator G. The unit 110, a switching unit 120, and an output voltage sensing unit 140 are basically included. The input power detector 110 propagates the state to the ATS controller 130 when the commercial power input is below the reference level due to a power failure lamp, so that the ATS controller 130 basically operates the generator G. Start-up control and the switching unit 120 is controlled so that the power generated in the generator G is supplied to the load through the switching unit 120. Since this path switching operation is a general function of the ATS, a detailed description thereof will be omitted. For reference, in FIG. 2, the output voltage detector 140 is for detecting the generator output voltage, the current level, and the frequency (Hz), and the communication unit 150 provides the wired / wireless information or self-diagnostic information related to driving the generator (G). It is for transmitting to the ATS management server system 400 according to the line communication network format, and the user I / F (InterFace) 160 includes a display unit for displaying self-diagnosis information externally and a data input device for setting various information. do. The alarm unit 170 is also preferably provided as an auxiliary means for outputting the alarm sound to the field manager.

Hereinafter, the self-diagnosis function of the ATS 100 will be described with reference to FIG. 3, which shows a detailed block of the ATS controller 130.

≪ Embodiment 1 >

First, the ATS controller 130 of the self-diagnostic type ATS 100 according to the first embodiment of the present invention is configured to increase the startability of the generator G, and includes a timer 131 for time setting and time counting. The temperature of the generator driving control unit 132 for starting and stopping the generator G and the temperature sensing sensor S1 for sensing the temperature around the generator G at a time when the commercial power input is cut off and at the set time is It includes a choke valve control unit 133 for closing the generator choke valve to increase the startability if the set temperature or less.

For reference, in the case of gasoline generator (G), the start up of the generator (G) should be started periodically. The reason for this is that the gasoline generators, which are widely used, adopt the Cabreta method. When the gasoline generator (G) of the Cabreta method is not used for a long time, gasoline residues remain in the Cabreta hole and the fuel hose, Lowers. Therefore, the generator (G) must be started periodically to maintain good startability. When the generator (G) manager sets the generator (G) start cycle and operating time (for example, 30 minutes every 15 days) through the user I / F 160, the generator drive control unit 132 is set And the generator (G) can be commissioned in accordance with the operating time. As a result, the startability of the generator G can be maintained in an optimal state.

On the other hand, the choke valve control unit 133 senses the temperature around the generator G at every generator startup and closes the generator G choke valve when the generator temperature is lower than the set temperature, thereby improving startability. The reason for this is that when the temperature around the generator G is high, such as in summer, the gasoline diffuses. If you close the choke valve, it will get a lot of fuel when the air and fuel are mixed. If the gasoline is large, the spark plug will be wetted by the fuel. If the spark plug is wetted by fuel, the spark will not bounce and will not start. Therefore, the choke valve control unit 133 of the ATS control unit 130 according to the embodiment of the present invention increases the startability by opening the choke valve when the temperature read by the temperature sensor S1 is high, on the contrary, when the temperature is low, the choke By closing the valve to supply a large amount of fuel to increase the start-up, it is possible to always maintain the optimum startability without being affected by the temperature around the generator (G).

For reference, the temperature sensor S1 for detecting the temperature around the generator G may be mounted on the generator G by the manufacturer of the generator G, or may be shipped separately from the manufacturer of the ATS 100. By mounting on the generator (G) or installed in the surrounding environment can be implemented embodiments of the present invention.

≪ Embodiment 2 >

Therefore, in addition to the configuration of the ATS controller 130 mentioned in the above-described first embodiment, the temperature sensor S1 for detecting the temperature around the generator G and the generator G are detected from the output voltage detector 140. The ATS control unit 130 may be further configured to further include a power level management control unit 134 for storing the output voltage or current level in the internal memory and displaying the output voltage or current level to the user I / F 160.

The power level management controller 134 stores the voltage, current, and frequency levels output from the voltage / current sensing circuit constituting the output voltage detector 140 in a memory. This stored data is later transmitted to the ATS management server system 400, so that the server system 400 can check whether the generator (G) output voltage of each ATS (100, 200, 300) is overvoltage or undervoltage, overcurrent, or below a prescribed frequency. As a result, it is possible to promptly follow-up measures according to the check result, and as a result, it is possible to obtain an effect of stably maintaining the output quality of the generator (G).

On the other hand, the generator driving control unit 132 of the ATS control unit 130 according to the second embodiment checks whether the generator start completion and stop completion through the power level management control unit 134 at every generator start or stop, and start or stop when not completed Repeat the control operation up to the set number of times. If the generator G is not normally controlled despite the repetition, the alarm sound is output through the alarm sound controller 139 to be controlled by the manager.

Third Embodiment

In addition to the configuration of the ATS controller 130 mentioned in the above-described second embodiment, the ATS controller 130 according to the embodiment of the present invention is a battery charge voltage detector for detecting the charge voltage of the battery provided in the generator (G). 135, a fuel amount sensor S2 for detecting a generator fuel amount, a generator operating time counter 136 for accumulating the generator operating time, the battery charge voltage detector 135, and a fuel amount sensor ( S2) may further include a self-diagnostic management control unit 137 for storing and displaying the self-diagnosis information sensed or accumulated through the generator operating time counter unit 136 in the internal memory. As the modified system, the charging voltage detection unit 135 may be deleted from the ATS control unit 130 since the charge voltage detecting unit 135 is a component that can be provided in the generator G.

According to the third embodiment of the present invention, since the ATS controller 130 may store and manage the charge voltage and the use time of the battery through the battery charge voltage detection unit 135, the ATS controller 130 may store the information or monitor the information remotely. The server system 400 may propagate an abnormality or replacement time of the battery to the administrator. In the same manner, the generator operating time counter 136 checks the generator operating time to propagate the engine oil proper replacement time to the manager, and informs the manager of a state such as insufficient generator fuel amount through the fuel amount sensor S2. It can spread.

As such, the self-diagnosis result of the generator G may be propagated to the site manager or the external manager because of the additional configuration of the ATS controller 130 according to the fourth embodiment to be described below.

It further includes an alarm sound control unit 139 for propagating. Therefore, the alarm sound control unit 139 of the ATS control unit 130 outputs an alarm sound promptly when the stored self-diagnosis information exceeds a set standard or threshold, so that the site manager may take measures such as fuel shortage, oil change, and battery replacement. The self-diagnostic information of each ATS (100, 200, 300) by the information transmission control unit 138 is transmitted to the ATS management server system 400 located at a remote location through a wired or wireless line, so that the remote manager at each ATS (100, 200, 300). It will be able to take necessary A / S measures.

Hereinafter, the configuration and operation of the ATS management server system 400 that remotely manages self-diagnostic information transmitted from each of the ATSs 100, 200, and 300 configured and operated as described above will be described with reference to FIG. 4.

4 illustrates a block diagram of the ATS management server system 400 of FIG. 1.

As shown in FIG. 4, the ATS management server system 400 is a system capable of communicating with a plurality of self-diagnostic ATSs 100, 200, 300 through wired and wireless lines, and a communication unit 410 for communicating with a client self-diagnostic ATS 100, 200, 300. ). And a server controller 420 which controls the overall operation of the management server system 400. The server controller 420 stores the self-diagnosis information of each ATS transmitted through the communication unit 410 as client information which is a memory device. The self-diagnostic information storage unit 421 for storing and managing in the DB 430, the self-diagnostic information analyzing unit 422 for comparing the stored self-diagnostic information with a threshold value for each item, and the self-diagnostic information of any item have a threshold value. If it does not meet the criteria includes an information message propagation unit 424 for propagating management information messages to the corresponding ATS manager terminal (mobile phone, mail account, etc.). In some cases, the server controller 420 may further include a client program updater 424 for updating the control program data of each client, ATS, as needed.

The self-diagnostic information storage unit 421 of the configurable management server system 400 divides the self-diagnostic information transmitted from each ATS 100, 200, and 300 connected by the client ID into the client information DB 430. For reference, the client information DB 430 stores and manages at least a client ID, equipment manager information of each client, and self-diagnosis information of each client. The self-diagnostic information analysis unit 422 then stores the self-diagnostic information stored at each time of storing the self-diagnostic information (battery charge voltage level, generator operating time, generator fuel amount, generator output voltage, generator start-up and stop-stop count, etc.). If the self-diagnosis information of any item does not satisfy the threshold criterion, the information is passed to the information message propagation unit 423. The information message propagation unit 423 then propagates the management information message including the self-diagnosis result and action information to the corresponding ATS manager terminal (mobile phone, mail account, etc.). As a result, the ATS equipment manager can promptly follow up the ATS or generator through his email account or his mobile phone. In some cases, a prompt A / S can be made by propagating a management information message to an A / S man located near the failed ATS (100, 200, 300).

Therefore, the ATS management server system 400 according to the embodiment of the present invention receives the self-diagnosis results of each ATS system from a remote location, manages them integrally, and promptly propagates the method for removing the failure factor to the administrator, thereby providing ATS. Not only can the administrator's convenience be provided, but the AS can be provided quickly.
