Description
Technical Field
The present invention relates to a multi-function housing system for performing error recovery of a control module, and more particularly, to a multi-function housing system using a first control module and a second control module, which are 2 microcomputers, and performing repair in different ways when an error occurs in each of the modules, thereby improving the stability of the system.
Background
With the recent deterioration of the concentration of fine dust, attention has been paid not only to the air quality of the indoor space but also to the treatment and management of clothes, shoes, quilts, and the like to which various contaminants floating outdoors and indoors may adhere. Along with this, devices for removing pollutants and managing clothes, shoes, quilts, etc. have been developed, and there is an increasing trend toward devices having various functions associated therewith.
Generally, a laundry care device cleans laundry through processes of shaking dust, humidifying, dehumidifying, and ending up. Such steps of shaking dust, humidifying, dehumidifying, and ending up are controlled by a microcomputer (hereinafter, referred to as 'microcomputer') provided in the laundry care apparatus, and more specifically, electronic devices such as a blower, a heat pump module, and the like provided in a machine room of the laundry care apparatus are controlled by the microcomputer, thereby realizing cleaning of the laundry.
The microcomputer may be a micro computer having a pad on which an interface circuit of a storage device, a peripheral device, or the like is mounted, and may be a microprocessor constituting a calculation processing unit of the computer by one or a plurality of large scale integrated circuits (LSIs), and may be a variety of devices that receive various control signals and electric signals and control and drive the received electric signals. The microcomputer can store various algorithms and data for directly controlling the electronic product, and can process and generate control signals each time a specific input signal is received.
For example, when a command for operating the laundry care device is input to a microcomputer provided in the laundry care device, a signal for controlling a blower, a heat pump module, and the like is output by means of a stored algorithm or calculation of data, thereby performing the entire process of cleaning the laundry.
Further, the microcomputer may malfunction due to various factors such as an operation error that may occur during repeated operations, input of noise and an error signal. For example, the microcomputer may fail to receive or react to an external signal due to a surge (surging) such as a system failure, and may fall into a faulty operation state such as a popping phenomenon that an output signal completely different from an expected signal is generated. Accordingly, if an erroneous operation state of the microcomputer occurs, the electronic device mounted with the microcomputer and various devices including the same cannot be normally controlled or operated, and thus it is necessary to recognize and correct the erroneous operation state.
As a prior art for detecting an erroneous operation state of a microcomputer and recovering it, korean laid-open patent publication No. 1997-0071209 is disclosed. The above-mentioned prior art is a "microcomputer operation monitoring control device", and discloses a control device which is provided with an external monitoring timing unit and automatically initializes a microcomputer when the normal operation of the microcomputer is resumed. However, the conventional technology is configured by using a single microcomputer, and there is no means for replacing such a microcomputer when an erroneous operation occurs, and thus there is a problem that the conventional technology is poor in terms of maintaining system stability.
Therefore, recently, there has been an increasing interest in the necessity of a technology for controlling the laundry treating apparatus using a plurality of microcomputers, thereby improving the stability of the system and enabling the laundry treating apparatus to normally operate even when a malfunction of a specific microcomputer occurs.

Detailed Description
The present invention will be described in more detail below with reference to the accompanying drawings. In the following, the 'multifunctional storage system' will be described with reference to a case where clothes are stored in a storage chamber and cleaned, but it is obvious that articles requiring periodic cleaning, such as bedding and a doll, may be stored in the storage chamber and cleaned, in addition to the clothes.
The "program" used in the following is a generic concept of the "mode", and for example, the "laundry care program" is a concept in which the "pretreatment mode", "humidification mode", "dehumidification mode", and "post-treatment mode" are connected in a time series manner. The user can select 'program' or only 'mode'.
1. Description of the Structure of the multifunctional storage System
Referring to fig. 1 to 3, the multifunctional receiving system according to the present invention includes a receiving chamber 100, a machinery chamber 200, a recycling module 300, a memory part 410, and control modules 401 and 402.
The storage chamber 100 is a space for storing clothes and the like and removing contaminants, malodorous substances, and the like. Therefore, the natural humidified air flows as the circulating air after the interior of the storage chamber 100 has risen to a high temperature, and can be circulated. A circulation filter attachment portion (not shown), a circulation air inlet port, and a circulation air outlet port are disposed on a lower surface of the storage chamber 100. The circulation filter attachment/detachment portion is an opening through which the circulation filter unit 229 located in the machine room 200 can be easily attached/detached for maintenance, replacement, or the like of the circulation filter unit 229.
The circulation air inlet 141 and the circulation air outlet 142 are openings for allowing circulation air inside the housing chamber 100 to flow in and out of the machine chamber 200, respectively. The circulation air inlet port is formed to communicate with the fan unit 230 and discharge air from the machine chamber 200 toward the storage chamber 100, and the circulation air outlet port is formed to circulate air from the storage chamber 100 toward the machine chamber 200. Further, a portion of the inside of the receiving chamber 100 communicating with the circulation air inflow port is formed to be inclined toward an upper side direction, and the air flowing in from the circulation air inflow port is discharged toward the inside of the receiving chamber 100 (meaning not discharged in a vertical direction, but discharged obliquely) with a predetermined angle toward an upper side from a bottom surface of the inside of the receiving chamber 100. Accordingly, compared to the case where the circulation air discharged from the circulation air inlet is in the vertical direction, the cleaning efficiency can be improved by contacting the clothes or the like stored in the storage chamber 100 with a wider area.
The machine room 200 has a function of circulating air by allowing air to flow in from the storage room 100 and filtering the air in the 'laundry care program', and then allowing natural humidified air to flow out as circulating air. The machine room 200 includes an air inlet 210, a first flow path 220, a fan unit 230, a second flow path 240, an air outlet 250, a dehumidifier 260, a supply water tank 270, and a condensation water tank 280.
The intake port 210 is a portion for taking in outside air into the machine room 200. The air outlet 250 is a portion that receives the filtered outside air from the second flow path 240 and discharges the same to the outside. The suction port 210 and the discharge port 250 can be opened or closed according to selection. A cleaning filter unit attachment part (not shown) is provided in the air inlet 210, and a cleaning filter unit 219 can be provided. The cleaning filter unit 219 plays a role of filtering external air sucked in an 'air cleaning mode' as another process of the multifunctional storing system, and may include a pre-filter, a high efficiency air filter, and the like, but is not limited thereto.
The first flow path 220 is communicated with the suction port 210, the second flow path 240, and the fan unit 230. A circulation filter unit 229 is provided inside the first flow path 220. The circulation filter unit 229 can function to filter the circulation air. Since the circulation filter unit 229 may include a humidification filter, when water staying in the supply water tank 270 is supplied to the humidification filter, moisture is supplied to the circulation air passing through the humidification filter, thereby forming natural humidified air. The user can attach and detach the circulation filter unit 229 by opening a door (not shown) and approaching a circulation filter attaching and detaching portion (not shown).
When the fan unit 230 is operated, the air in the storage chamber 100 flows into the second flow path 240 through the circulating air outlet 142, and flows into the first flow path 220 again to face the fan unit 230. In this process, the air passes through the humidifying filter of the circulation filter unit 229 to become natural humidified air. It is supplied to the receiving chamber 100 again through the second flow path 240 and through the circulating air inflow port. This process is repeated, thereby continuously circulating the circulating air between the housing chamber 100 and the machine chamber 200. The circulating air may contain pollutants or malodorous substances in the receiving chamber 100, and provide a comfortable environment to the user since they are not discharged to the outside.
The second flow path 240 receives filtered outside air or circulated air from the fan unit 230. The second flow path 240 selectively communicates with one of the storage chamber 100 and the exhaust port 250, and includes a first flow path switching member 241 and a second flow path switching member 242 for controlling the same. The first channel switching member 241 and the second channel switching member 242 change the channel by operating in pairs. In one embodiment, the first flow channel switching member 241 and the second flow channel switching member 242 may be rotatable about an axis, or may be configured to selectively change the flow channel.
The dehumidifying part 260 performs a function of dehumidifying the circulating air flowing in the receiving chamber 100. The dehumidifying part 260 may be, for example, a heat pump, but is not limited thereto. The dehumidifying part 260 may generate heat during the process of performing dehumidification, but the heat is not discarded and may be utilized for laundry care. For example, after the housing chamber 100 is heated to about 50 to 70 degrees celsius by heat generated during dehumidification in the dehumidification section 260, the room temperature circulating air is received from the second flow path 240 through the circulating air inlet, so that contaminants and malodorous substances such as laundry can be removed. As another example, as described above, the heat generated during the dehumidification in the dehumidification unit 260 is supplied to the humidification filter of the circulation filter unit 229 or the pipe connecting the supply water tank 270 and the humidification filter, so that the natural humidified air performing the circulation air function can be heated. The above temperature is an example, and is not limited thereto, and various modifications may be made. Further, it is also possible to selectively operate one of the dehumidifying part 260 and the circulation filtering unit 229 (i.e., the humidification filter) so as not to interfere with each other.
The water supply tank 270 retains water to be supplied to the humidification filter provided in the circulation filter unit 229. For this purpose, a pipe is connected to the circulation filter unit 229. The condensed water tank 280 collects and accumulates condensed water generated in the housing chamber 100, or condensed water generated in a process in which saturated humid air generated in the housing chamber 100 flows into the first flow path 220, the second flow path 240, or the like of the machine chamber 200 and condenses. For this purpose, the receiving chamber 100 and/or the first flow path 220 and/or the second flow path 240 are connected by a pipe. In order to fill the water or remove the filled condensate, it is preferable that both the supply tank 270 and the condensate tank 280 of the user be easily accessible.
The machine chamber 200 may be located in any direction with respect to the storage chamber 100, but is preferably located at the lower portion of the storage chamber 100. This is because condensed water or saturated humid air condensed in the storage chamber 100 can flow into the machine chamber 200 by its own weight and be discharged to the outside through the condensed water tank 280.
The recirculation module 300 facilitates circulation of the circulating air. Since the recirculation module 300 recirculates the circulating air at the upper side of the receiving chamber 100, a convection phenomenon can be more smoothly performed in the entire receiving chamber 100. In addition, since the recirculation module 300 operates independently of whether the machine chamber 200 is operated, it is also possible to operate to remove contaminants such as laundry stored in the storage chamber 100. Although fig. 1 to 3 illustrate the state in which the recirculation module 300 is provided, it is needless to say that the recirculation module 300 may not be provided. Even if the recirculation module 300 is provided, the recirculation module 300 does not operate and can operate independently when the fan unit 230 operates.
The memory unit 410 is a space for storing information for the multi-function storage system. The Memory unit 410 may include an EEP-ROM (electrically Erasable Programmable read Only Memory), but is not limited thereto as long as it can store Memory. The EEP-ROM can perform writing and deleting of information by means of the control modules 401, 402. The EEP-ROM may be configured as a non-volatile memory (non-volatile memory) that retains, but does not erase, information stored therein even if power supply is stopped due to power-off. In the following description, the memory unit 410 and the control modules 401 and 402 are described as being separated, but this means functional separation, not physical separation. Depending on the system and apparatus embodied, the memory portion 410 and the control modules 401, 402 may be formed as one piece.
The first control module 401 is electrically connected to the operation unit 610. The user selects a desired program or mode, inputs the selected program or mode to the operation unit 610, and the first control module 401 transmits an operation signal to the second control module 402. As shown in fig. 1, the operation unit 610 is disposed on the outer surface of the door 600 for the convenience of the user's input operation. In addition, in order to visually provide information on the state of the multifunctional storage system currently in operation to the user, a display panel is provided, and the display panel may be formed in a touch manner for the user to input.
The second control module 402 is a module that electrically controls the components located in the machine room 200. The second control module 402, which receives the operation signal from the first control module 401, electrically transmits a command signal to the components inside the machine room 200, thereby operating them. For example, the user selects a laundry care program, which means that the laundry care program is selectively input to the first control module 401, and the second control module 402 receives operation signals related to the execution in a time-series manner for the pre-treatment mode, the humidification mode, the dehumidification mode, and the post-treatment mode constituting the laundry care program from the first control module 401, and controls the operations of the configurations corresponding to the respective modes.
The first control module 401 and the memory unit 410 are disposed on the housing chamber 100 side, and can prevent electrical interference with the structure in the machine chamber 200. The second control module may be disposed in the machine room 200.
2. Description of mechanical Chamber mode of Multi-functional storage System
(1) Description of laundry care program
Step S100 is a step of performing a 'laundry care program'.
The machine room 200 may perform detailed processes constituting the laundry care program, i.e., a pre-treatment mode, a humidification mode, a dehumidification mode, and a post-treatment mode. Hereinafter, the laundry care program will be described by being roughly divided into a pre-treatment mode, a humidification mode, a dehumidification mode, and a post-treatment mode, but an additional mode related to cleaning of laundry may be added. In addition, the operation of the laundry care program may be performed such that the pre-treatment mode, the humidification mode, the dehumidification mode, and the post-treatment mode are sequentially performed, but the pre-treatment mode and the post-treatment mode may be partially or entirely omitted according to the selection of the user.
1) Description of the humidifying mode
Referring to fig. 2, the operation of the structure of the machine chamber 200 in the humidification mode will be described.
In the humidification mode, air sucked by the fan unit 230 is formed as natural humidified air while passing through the circulation filter unit 229. The circulation air inlet and the circulation air outlet are opened to circulate the natural humidified air into the storage chamber 100. The humidifying filter may be disposed in the circulation filter unit 229, and water may be supplied from the water supply tank 270 to the humidifying filter of the circulation filter unit 229, or water retained in the water supply tank 270 may be forcibly supplied by a supply pump (not shown).
The humidification mode circulates natural humidified air to the storage chamber 100, thereby humidifying the internal environment of the storage chamber 100. Accordingly, the clothes stored in the storage chamber 100 can be humidified. Air particles contained in the naturally humidified air are combined with pollutant particles and malodor particles adhered to the laundry, and when the dehumidifying mode, which will be described later, is operated, the pollutant particles and the malodor particles are removed from the laundry together during dehumidifying the laundry.
In fig. 2, the fan unit 230 is described as an intake fan, but may be formed as an exhaust fan, and in this case, the arrangement of the structure inside the machine room 200 may be rearranged so as to be suitable for the exhaust fan.
2) When operating in dehumidification mode
Referring to fig. 3, the operation of the structure of the machine chamber 200 in the dehumidification mode will be described.
In the dehumidification mode, the dehumidification unit 260 in the machine chamber 200 operates to dehumidify the circulation air flowing through the storage chamber 100. The fan unit 230 is operated to circulate the dry air and open the circulation air inlet and the circulation air outlet 142 in order to dehumidify the storage chamber 100. Condensed water generated during the dehumidification mode operation may be retained in the condensed water tank 280. By performing the dehumidification mode, the pollutant particles and the malodor particles stuck to the laundry can be removed from the laundry.
3) During pre-processing mode and post-processing mode
Referring to fig. 3, the operation of the structure of the machine chamber 200 in the pre-treatment mode and the post-treatment mode will be described.
The pre-treatment mode performs a role of discharging air as a starting step of a laundry care program, thereby primarily removing dust or contaminants having a relatively large size of particles stuck to the cloth or the like. The pretreatment mode is also called an 'air shower mode', and means a process of strongly injecting air. Before the contaminants and the like adhered to the laundry in the storage chamber 100 are formally removed, the contaminants are shaken in advance, thereby improving the cleaning efficiency of the laundry. In the pretreatment mode, the circulation filter unit 229 and the dehumidifier 260 are not operated, and only the fan unit 230 is operated.
The post-treatment mode is a finishing step of the laundry care program, and performs a function of re-drying the inside of the storage chamber 100 while supplying air through the fan unit 230 to remove foreign substances that may remain in the laundry again. The post-processing mode is also referred to as 'air smoothing mode'. Although the operation of the structure of the robot chamber 200 in the pre-treatment mode and the post-treatment mode is the same, the output of the fan unit 230 may be controlled differently from each other. For example, the output of the fan unit 230 in the pre-treatment mode may be formed relatively larger than the output of the fan unit 230 in the post-treatment mode.
In addition, in the present specification, the humidification mode and the dehumidification mode are performed between the pre-treatment mode and the post-treatment mode, and the humidification mode and the dehumidification mode may be repeatedly performed a plurality of times, so that the user can adjust the number of times of performing the humidification mode and the dehumidification mode according to the type of the laundry or the type of the laundry stored in the storage chamber 100.
In the pre-treatment mode and the post-treatment mode, the housing chamber 100 and the machine chamber 200 are both communicated with each other, and are preferably performed in a state isolated from the outside air. In particular, when the pre-treatment mode is performed, if the machine chamber 200 is not isolated from the external air, the foreign particles inside the housing chamber 100 may be discharged to the outside of the multifunctional housing system, so that the air quality of the space in which the multifunctional housing system is disposed may be deteriorated. In the post-processing mode, in order to isolate the influence of humidity and temperature on the space in which the multifunctional housing system is disposed, it is preferable to operate the machine room 200 in a state isolated from the outside air.
(2) Description of air cleaning mode
Referring to fig. 4, the operation of the structure of the machine room 200 in the air cleaning mode will be described.
The air cleaning mode is a mode in which only the machine chamber 200 is operated to perform a function of cleaning the outside air, independently of the storage chamber 100. That is, in a state where the outside air is contaminated, since clean clothes and the like can be placed inside the storage chamber 100, the operation mode is an operation mode in which the outside air does not flow into the storage chamber 100.
When the user selects the air cleaning mode, the exhaust valve 650 of the door 600 is opened and the intake port 210 is also opened.
The first flow path switching member 241 and the second flow path switching member 242 of the machine chamber 200 operate to isolate the second flow path 240 from the housing chamber 100 and the first flow path 220 while communicating with the exhaust port 250. In this process, the housing chamber 100 and the machine chamber 200 are independent spaces.
The fan unit 230 operates. Due to the operation of the fan unit 230, the external air flows into the first flow path 220 through the suction port 210 toward the fan unit 230. In passing through the suction port 210, the external air is filtered by means of the cleaning filter unit 219 provided at the suction port 210. During the passage through the first flow path 220, further filtration may be performed by means of a circulation filtration unit 229 located in the first flow path 220. As described above, since the humidification filter located in the circulation filter unit 229 is dried in the process of forcibly circulating the air by the fan unit 230, the humidification filter supplied with water from the supply water tank 270 is dried at ordinary times, thereby preventing the proliferation of bacteria on the humidification filter and solving the problem of generation of bad odor at a time. The filtered outside air passing through the fan unit 230 passes through the second flow path 240 and is exhausted to the outside through the exhaust port 250.
By repeating this process, the multifunctional storing system according to the present invention performs a function of an air cleaner. The external air continuously flows into the machine room 200 and is filtered, and the filtered air is continuously discharged.
It is preferable because the air cleaning mode can be performed regardless of whether the user opens the door 600. During the air cleaning mode operation, the user can locate laundry or the like inside the receiving chamber 100 or take out the laundry or the like by freely opening the door 600. The water in the condensed water tank 280 can be discharged as needed by filling the water tank 270 with water. Since the door 600 does not cover the air inlet 210 and the air outlet 250 is opened inside the door 600, the opening of the door 600 does not affect the operation of the air cleaning mode.
The user can confirm whether to operate in the air cleaning mode or the laundry care program at present by confirming only whether to open the exhaust valve 650 at a position far from the multifunctional storing system, that is, a position where the operating part 610 is not clearly seen.
3. Description of error recovery of control module of multi-functional housing system
(1) Upon confirmation of error of the first control module
When an error of the first control module 401 is confirmed, a method of recovering the error will be described with reference to fig. 5 and 6.
The first control module 401 is electrically connected to the memory part 410 so as to be communicable, which may be constituted by a wire harness connected by wire.
The error recovery method of the first control module 401 includes steps S100 to S124.
The error confirmation of the first control module 401 may be performed by a watchdog (watch-dog) as a monitoring means. The watchdog may be configured to check the abnormal state of the first control module for a predetermined time period. More preferably, it may be constructed in a real-time confirmation manner.
Step S100 is a step of initializing the first control module 401, which means reset.
Step S110 is a step in which the first control module 401 loads control information from the memory section 410. The operation of the machine room 200 described above may store the mode information of the machine room 200 in the memory unit 410 every time an arbitrary mode is ended. The first control module 401 can receive the mode and the type of program currently in operation and provide the remaining time information through the memory section 410.
Step S120 includes steps S121 to S124 as a step in which the first control module 401 transmits an operation signal to the second control module 402 using the control information loaded from step S110.
Specifically, step S121 is a step of restoring the first control module 401 using the control information. In this process, the display panel linked with the first control module 401 may be configured to display the restored control information.
In step S122, the first control module 401 confirms whether the machine room 200 is in the humidification mode or the dehumidification mode using the control information. If the machine chamber 200 is executing the humidification mode, the residual moisture remains in the current storage chamber 100, and if the residual moisture is not removed, there is a risk of damaging the clothes. If the machine room 200 is executing the dehumidification mode, it means that the dehumidification mode is not completed, and in this case, a problem of residual moisture remaining may occur. That is, in step S122, it is a step of checking whether or not residual moisture is present in the storage chamber 100 at present in association with the execution of the forced dehumidification mode to be executed later.
Step S123 is a step in which, when it is confirmed that the machine room 200 is performing the humidification mode or the dehumidification mode in step S122, which is a previous step, the first control module 401 transmits an operation signal for performing the forced dehumidification mode of the machine room 200 to the second control module 402. That is, it means that the residual moisture is present in the current state of the storage chamber 100 and the residual moisture needs to be removed.
Step S124 is a step of generating an operation signal of the forced dehumidification mode of the machine room 200 by means of the second control module 402, and performing the forced dehumidification mode of the machine room 200. The 'forced dehumidification mode' may operate in the same manner as the 'dehumidification mode', but specific control information such as dehumidification intensity and time may be different.
The forced dehumidification mode of the machine chamber 200 executed in step S124 may be set such that the dehumidification intensity or the execution time of the forced dehumidification mode is variable, and the dehumidification intensity or the execution time of the forced dehumidification mode depends on the execution time of the humidification mode of the machine chamber 200. The humidity of the storage chamber 100 varies depending on the execution time of the humidification mode, and is set in the first control module 401 or the second control module 402 according to the execution time of the humidification mode and the humidity of the storage chamber 100, so that it is not necessary to dispose an expensive and precise humidity sensor inside the storage chamber 100.
(2) Upon confirmation of error of the second control module
When an error is confirmed in the second control module 402, a method of recovering the error will be described with reference to fig. 7 and 8.
The second control module 402 is electrically connected to the first control module 401 so as to be communicable, which may be constituted by a wire harness connected by wire. The first control module 401 and the second control module 402 may be provided with communication modules (not shown) for wireless communication.
The error recovery method of the second control module 402 includes steps S200 to S232.
Step S200 is a step of initializing the second control module 402, which means reset.
Step S210 is a step in which the second control module 402 requests control information from the first control module 401. In step S200, since the second control module 402 performs initialization, the operation of the components of the machine room 200 is reset in a very short time, for example, several milliseconds (ms), and the second control module 402 requests the first control module 401 for control information, so that the provision of control information including a currently-in-progress program, a mode, and a remaining time is available.
Step S220 is a step in which the second control module 402 receives control information from the first control module 401.
Step S230 is a step of generating an operation signal using the control information received by the second control module 402 in step S220, and specifically includes step S231 and step S232.
In step S231, the second control module 402 checks whether the machine room 200 is operating or not based on the control information. That is, whether the machine room 200 is in operation or in a standby state is confirmed for the first time.
Step S232 is a step of generating an operation signal to continue the operation of the machine room 200 when it is confirmed in step S231 that the machine room 200 is operating. More specifically, the control information includes mode information of the machine room 200, remaining time information of the mode being executed (or execution time information of the mode), and program information in which different modes are combined in a time-series manner. In order to continuously perform the operation of the machine room 200, the remaining time information and the residual mode information are included, and the operation signal means an electric signal for the remaining time information and the residual mode information.
In addition, the operation signal in step S232 may further include a compensation operation signal. The compensation operation signal may relatively further increase the humidification intensity or humidification time in the humidification mode. Also, the dehumidification intensity or the dehumidification time may be relatively further increased in the dehumidification mode. As a modification example described above, the humidification intensity and the dehumidification intensity may be increased intensively only for a set time period, and the humidification intensity and the dehumidification intensity may be returned to the normal state again when the humidification mode and the dehumidification mode are executed for a time period longer than the set time period.
(3) If the communication error between the first control module and the second control module occurs
Referring to fig. 8, a communication error between the first control module 401 and the second control module 402 will be described.
The first control module 401 and the second control module 402 are configured to communicate using electrical signals and communicate with each other in a protocol.
At this time, when the second control module 402 requests the first control module 401 for control information, if the transmission signal of the second control module 402 does not match the protocol of the first control module 401, the error recovery is performed by executing steps S310 to S330.
Step S310 is a step in which the first control module 401 processes the transmission signal of the second control module 402 into an invalid value. The first control module 401 and the second control module 402 set ranges of transmission/reception protocol values, respectively, and if the values are not within the set ranges, the values are processed as invalid values.
Step S320 is a step in which the second control module 402 retransmits the transmission signal of the retransmission request control information to the first control module 401, and retransmits the transmission signal within the set number of times until the first control module 401 processes the transmission signal to a valid value. In this case, when the second control module 402 newly requests the control information from the first control module 401, the request is made in a cycle of the set time.
Step S330 is a step of initializing either the first control module 401 or the second control module 402 if the number of retransmissions of the transmission signal from the second control module 402 to the first control module 401 exceeds the set number of retransmissions in step S320. In this process, of course, the first control module 401 and the second control module 402 may be initialized, and if the first control module and the second control module are not processed to the valid value even when all the first control module and the second control module are initialized a predetermined number of times, a warning may be given to the user to notify the user of a failure or damage on the communication interface side.
While the present invention has been described with reference to the embodiments shown in the drawings, it is to be understood that the same is by way of illustration and example only and that various modifications and equivalent other embodiments will be apparent to those skilled in the art from this disclosure. The scope of protection of the invention shall be determined by the patent claims.
