Abstract

The present invention relates to a maintenance support system of a non-step boiler system, which is formed with a plurality of control devices such that a failure does not occur when a boiler operates and with main and auxiliary driving devices on a boiler driving device such that even if a failure occurs in one control device, another control device normally operates, which is improved to operate a boiler without a stop by operating the boiler continuously even if a failure occurs in a driving device so as to transmit information on a component or module, in which a failure occurs, to a maintenance data center through a wired/wireless communications network and to transmit predicted repair cost consumed to replace a corresponding component to a consumer, and which repairs a module, in which a failure occurs, at a scheduled date and time when the consumer selects a visit repair date and time and replies the same. A boiler system is improved to support to use a boiler continuously without a failure while a user does not recognize whether a failure occurs in the boiler, and to repair the boiler quickly at a reasonable price. Most of boilers commercialized so far are operated in a method that if a failure occurs in a core driving device while a boiler is operated by using one control device, an error code is displayed, and the boiler is immediately stopped so that a user calls an after-service center and repairs the failure, which causes inconvenience of the user. According to the non-stop boiler system connected to the Internet or a data cellular communications network and using the same, an auxiliary driving device is provided with a core driving device in addition to control of a boiler, and thus even if a failure occurs in one device during parallel operations, a non-stop operation can be secured with another one device.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a dual motor drive apparatus and an unstable low noise boiler system using the same,

In order to prevent inconvenience that the boiler for hot water and heating suddenly breaks down due to a failure 15 and is not operated, the power supply device 5 and the control circuits 2, 3, Even if one power supply device 5A and one control circuit 2A, 3A, and 4A and the driving devices 12, 13, 61, and 64 fail, (2B, 3B, 4B) and driving devices (12, 13) so that the heating and hot water supply (32B) can be operated without interruption.

Existing commercialized heating and / or hot water electric, gas, solar, pellet, coal, light oil and barker oil boilers can be used to maintain the room temperature in the hot water circulation or steam circulation mode or to drive the boiler by burning the fuel to make hot water have.

The boiler operates normally in the range of the temperature set by the indoor temperature controller 6 or the mobile smartphone 11 and the boiler operating mode and the circulation pump 13 and the blower 12 and the control device 1 (32) suddenly stops hot water supply to the shower (32A) due to the sudden stop of hot water supply during the shower (32A), or even if an accident occurs in which the indoor temperature is lowered due to interrupted heating in cold weather It was a helpless operation until (20).

Even if the heating fuel is normally supplied, the boiler control 1, the hot water circulation 13 and the blower unit 12 can not be driven even when the supply of electricity to the power interruption 21 is interrupted, so that the boiler operation has to be stopped .

When the boiler failure time (15) is after the Friday work time, the call center (17) of the boiler after service provider switches to the automatic response mode and can not solve the heating or hot water use problem during the weekend, Most of existing existing boiler problems.

Even if the boiler is remotely controlled from the outside via the Internet or the mobile communication terminal smartphone 11 and the uninterrupted circuit in which the control device 1 of the boiler is double constructed, If a failure occurs in the drive unit and the sensor detects a signal out of the normal range, an error code 25 is generated, operation is interrupted (15), and a fault signal is transmitted remotely, When the repair is completed (20), the boiler does not work and heating and hot water supply must be stopped (19). For most boiler operating environments, if the boiler fails (15), call the call center (17) to explain the fault condition, and then the boiler is stopped until the fault repair worker (18) (19), and even when the boiler did not operate due to the power failure (21), until the electricity supply was normalized.

In order to solve the problems of the conventional boiler, the uninterruptible boiler according to the present invention comprises two power circuits 5A and 5B and two control circuit modules 33 and 34, The control circuit 33 operates the other one of the switches 5B and 34 in an abnormal state and outputs an error code 25 corresponding to the cause of the failure via the wired / 26) to visit the site with the faulty parts (18) and repair the fault (28), so that the boiler can be used without interruption.

The circulation pump 63 and the air blowing device 60 are constituted by the dual drive devices 12D and 12D in case a failure occurs in the boiler core drive device such as the circulation pump 13D and the blowing device 12D, 13D, 61, 62, 64, 65), so that when one of the drive units 61, 64 fails, the other drive units 62, 64 are operated to prevent the boiler from stopping, .

In order to prevent the boiler control or the drive from being stopped by the electrostatic charge 21, the secondary battery 22 is normally charged with the power supply device and the control circuit 1F and the drive devices 12D and 13D are operated So that the boiler can be normally operated for a predetermined time 21 during which the power supply is interrupted.

When an error code 25 is transmitted or recorded in accordance with various troubles caused by the operation of the boiler and an error code is transmitted to the owner or the after-service service data center 26 through the wired / wireless communication network, When the reservation is completed by sending a message to the boiler owner mobile communication terminal and requesting the reservation date and time, the boiler installation site is visited and repaired, so that the uninterrupted boiler can be continuously used. The boiler is improved to a boiler system that can be used in an uninterrupted state without a fault.

Particularly, it is possible to predict the replacement time based on the information of the failure after the use of the parts or modules whose mechanical lifetime has been determined, such as circulation pump 63 or blower 600, for a certain period of time. Implementation is possible.

Boiler User: Compared with the conventional boiler system, which can not operate normally for a certain period of time after the repair request is made after the boiler trouble occurs due to the sudden interruption of heating or hot water in winter, However, if boiler control device, power supply device or drive device fails in a certain life cycle, boiler can be operated normally by other control device and power supply drive device, and even if power failure Time You can use normally and do not have to hurry to visit or replace a failed part or module, send the error code or the code of the fault to send the expected part price and repair cost to the boiler owner and check the date and time I have a failed component Since the module needs to be repaired, the after-sales service provider can afford to repair it, and consumers can use the boiler without inconvenience.

In the case of a boiler that can operate without interruption for a fixed period of time depending on the capacity of the rechargeable secondary battery even during a power failure, even if there is a power outage or momentary power failure compared to a neighboring boiler that does not operate during a power failure, .

Boiler supply and service companies: It is very difficult to support the service according to the urgency of the user when replacing after the failure of the part or module according to the life cycle determined by the lifetime among the basic components for operating the boiler. However, , It sends the price of the part or module that needs to be replaced according to the error code sent to the database of the failed part or module to the data center database and the estimated price of the repair cost to the customer and reserves the date and time It is improved to be able to operate the trouble-free repairing operation in an unstable state by reserving the parts in advance by the customer in advance reserving the possible time, and it is possible to support the customer efficiently with the minimum service manpower and reduce the cost. Inconvenience caused by failure It is not whether it is possible to improve customer satisfaction.

The boiler control unit of the present invention includes two microcontrollers 2A and 2B, memories 3A and 3B, input / output control units 4A and 4B, and power supply circuits 5A and 5B in a module form If one module (33: 2A + 3A + 4A) fails and an error code is generated, the existing boiler sends an error message to the control unit 6 and displays an error message. However, (14E) by waking up the user (34: 2B, 3B, 4B) to operate normally (14E), so that the user does not know that the trouble has occurred and continuously operates the shower (32B) do.

However, the boiler control unit 33 transmits the fault occurrence details 25 to the data center 26, and transmits the repair parts and repair cost estimated prices to the boiler owner's mobile phone (40) The owner of the boiler can check the date and time of the visit to help repair the repair, but the existing boiler can afford to repair without the need for urgent repairs, such as when the boiler failed.

All the information such as the settings stored in the memory 3A of the two control modules 33 and 34 is mirror-copied to the memory 3B of the other control module at predetermined time intervals and the same information is stored in the two memories 3A and 3B So that the boiler can operate uninterruptedly with the other control module 34 even when one control module 33 fails.

Even when a failure occurs in one power supply unit 5A of the power supply units 5A and 5B, the power supply unit 5B is switched to the EKFMS power supply unit 5B so that the boiler can be used without interruption, Depending on the capacity of the secondary battery 22, the boiler can be used without interruption.

The conventional boiler has stopped operating even if the driving device or the control circuit such as the circulation pump 13 or the blower 12 has failed in addition to the control units 33 and 34. However, A driving device 52 and 53 such as two BLDC motors 38, 49, 42 and 43 are provided in each of the circulation pump 12D and the circulation pump 13D and one of them is normally driven, Even if it occurs, it is driven to the other one so that the user can continuously use the boiler which does not cause trouble, without inconvenience.

 The blowing device may be used by connecting two motors 961 and 62 in series to a Sikorsky type blower 60 used in a conventional boiler. However, as shown in FIGS. 4, 5 and 6 (12D) A rotor having the rotor magnets 38 and 42 of the BLDC motor is formed in the base disk 39 of the disk array 41 and the top disk 37 and the rotor 48 is wound around the inlet portion 48 of the casing 44 of the blower 46, And the disk array 41 is rotated through the BLDC motor drive circuit 52 to constitute a main BLDC motor stator coil on the opposite side to form a disk 57 between the disk 57 and the disk 58, It is possible to drive the boiler with low noise because the surface is blown by the boundary surface pulling effect and the centrifugal force without the wings without noise.

When the main BLDD motor is caused to stand by a drive circuit 53 and a failure occurs, the sub-BLDC motor drive circuit 52 is driven to blow the motor in an unsteady manner to cause the boiler to be driven in an unsteady manner. The code 25 can be transferred to the data center 26. The example of the after-service can be transferred 40 to the boiler owner and confirmed on the reservation date to enable the after service in an uninterrupted state.

The circulation pump may be used by connecting two motors 64 and 65 in series to the impeller-type circulation pump 63 used in the existing boiler. However, as shown in FIGS. 4, 5 and 6 (13D) 41 and the top disk 37 constitute a rotor having rotor magnets 38 and 42 of a BLDC motor so that an inlet portion 48 of the case 44 of the circulation pump 46 is connected to the sub- The coil 49 is constituted and the main BLDC motor stator coil is formed on the opposite side and the disk array 41 is rotated through the BLDC motor drive circuit 52 to form a boundary surface It is possible to drive a low-noise boiler by circulating hot water without noise due to traction effect and centrifugal force without a wing. Since it is a sealless structure that can not leak water to the rotating shaft of the power transmission device, there is no part to be broken by mechanical wear, Can be used.

When the main BLDD motor is driven to the drive circuit 53 and a fault occurs, the sub-BLDC motor drive circuit 52 is driven to drive the circulation pump in an unsteady manner so that the boiler can be driven in an unsteady manner. The generated error code 25 is transmitted to the data center 26, and an example of the after-service is transmitted to the boiler owner 40 and the reservation date is confirmed, so that the after-service can be brought to an unstable state.
