The administrator may be connected to the control device 500 through the user terminal 600 to manage the malodor measuring device 100 and / or the monitoring device 200. Although the user terminal 600 is shown separately from the control device 500 in this embodiment, the user terminal 600 and the control device 500 may be integrally formed.

The control device 500 can communicate with the malodor measurement device 100 and the monitoring device 200 to manage or control these devices and transmit / receive data. The control device 500 permits the access right to the user terminal 600 to enable the administrator to manage and control the malodor measurement device 100 and the monitoring device 200 or to allow the user to view the data .

The malodor measuring apparatus 100 includes a control unit 110, a communication unit 120, a sensing unit 130, a solenoid valve 135, a reference air supply unit 140, a measurement air supply unit 150, a pump 160, A cooling unit 170, a heating unit 175, a collecting unit 180, and a power supply unit 190.

The communication unit 120 can communicate with the control device 500. The communication unit 120 may include a wire / wireless communication module. In particular, the communication unit 120 may include any one of a mobile communication module, a wireless Internet module, and a local communication module. The mobile communication module transmits and receives radio signals to and from at least one of a base station, an external terminal, and a server on a mobile communication network.

The modules included in the communication unit may be included in other apparatuses (the monitoring apparatus 200, the control apparatus 500, and the user terminal 600).

The sensing unit 130 may be arranged as an array of a plurality of malodor sensors each measuring the degree of contamination of the fluid. The malodor sensor may be a semiconductor type gas sensor, an electrochemical sensor, an optical sensor, or the like.

The control unit 110 or the control unit 500 may measure the concentration of air pollution using the sensor value measured by the sensing unit 130. The malodor sensor of the sensing unit 130 can output a sensing value (generally, a voltage value) proportional to the concentration of the contaminant to be measured. A reference sensing value is required to calculate the contamination concentration or odor index from the measurement sensing value. The reference sensing value can be a sensing value at a specific concentration or odorless gas. The pollution concentration or the odor index can be determined from the measurement value by a specific ratio of the reference sensing value and the measurement sensing value or a specific calculation formula (hereinafter, referred to as 'reference value'). A specific ratio or a specific calculation formula can be derived from the characteristics of the odor sensor and the experimentally measured values. Therefore, although the reference value of the odor sensor is set to a specific specification at the time of shipment from the factory, the reference value may be changed or changed due to contamination or aging due to the manufacturing step of the sensor or the use of the sensor. Therefore, it is necessary to measure the reference sensing value at a specific concentration in order to correct the reference value.

The electromagnetic valve 135 is connected to a flow path through which the uncontaminated air (reference air) flows and a path through which the contaminated air (air to be measured) flows, and selectively connects any one of the non-contaminated air and the contaminated air to the sensing part 130). The solenoid valve 135 may be controlled by the control unit 110 or the monitoring device 200. It is preferable that the air to be supplied to the sensing unit 130 is supplied with the reference air in the early stage of one cycle and the measurement air is introduced into the remaining period. The reference air injection time may be shorter than the measurement air injection time.

The reference air supply unit 140 may provide the sensing unit 130 with a gas (reference air) having a specific concentration for correcting the reference value in the malodor sensor. The reference air is preferably a volatile / non-volatile gas or odorless air of a specific component whose concentration is known.

Referring to FIG. 3, the reference air supply unit 140 may include an activated carbon filter 142, an odorless air tank 144, and a reference air switching solenoid valve 146. The activated carbon filter 142 can deodorize the sucked atmospheric air. The air supplied to the activated carbon filter 142 may be air supplied to the measurement air supplier 150. The odorless air tank 144 may be a separate tank, and may store the deodorized air, that is, the reference air having no contaminants, and provide the sensing air to the sensing unit 130 when necessary. The odorless air tank 144 may store only a specific concentration of the substance or a specific gas harmless to the human body. For example, it is possible to store liquid nitrogen in place of odorless air, or to store butanol in which the reference concentration can be known. When the volatile substance butanol is stored, the reference concentration can be known based on the pressure or the volume in the flow path or the sensing portion.

The reference air switching solenoid valve 146 can change the type of the reference air flowing into the solenoid valve 135. [ The reference air switching solenoid valve 146 is connected to the air and odorless air tank 144 provided in the activated carbon filter 142 by the control signal of the control unit 110 or the signal of the monitoring device 200 (monitoring sensing operation unit 230) May be introduced into the solenoid valve 135. The solenoid valve 135 may be a solenoid valve. Preferably, the reference air supplier 140 provides odorless air as a basis and provides a specific gas inside the odorless air tank 144 when the sensed value (reference sensed value) for the odorous air is not within a predetermined range.

The measurement air supplier 150 may provide the sensing unit 130 with an external atmosphere to be measured by the sensing unit 130. The measurement air supplying unit 150 may further include a dust filter (not shown) for filtering dust in the outside air, and a water removing unit (not shown) for removing moisture in the outside air. The dust filter of the measurement air supplier 150 may be disposed in the inflow pipe and the outflow pipe of the water removing unit, respectively. The water removing unit may include a water removing valve (not shown) for discharging water generated in the outside atmosphere of the water removing unit to the outside.

The pump 160 supplies negative pressure to the sensing unit 130, the solenoid valve 135, the reference air supply unit 140, the measurement air supply unit 150, and each flow path (indicated by a bold line) Or the measuring air can flow in the required direction. The pump 160 can provide a necessary negative pressure in the collecting part 180 to be described later.

The collecting unit 180 can collect the odor air according to the signal from the control unit 110. The collecting unit 180 can discharge the collected air to the outside according to a signal from the control unit 110. [ The collecting unit 180 may include a collecting bag (not shown) for collecting and storing the collected collecting bags. The trapping bag can fill the outside air by the negative pressure or release the inside air to the outside by the positive pressure. The negative pressure or the positive pressure of the collection bag can be realized by the pump 160 or by a separate motor.

The cooling unit 170 can lower the temperature of each component. A method of operating the cooling unit 170 may be an air-cooled type comprising a motor and a fan, a water-cooled type using a motor and a cold water line, a contact type using a cooling element, and a system in which each system is mixed. The malodor measuring apparatus 100 is a kind of computer, and if the internal temperature is above the limit, the operation of each component may be incomplete or the operation state may be abnormal. The cooling unit 170 can prevent this state abnormality. However, the internal temperature of the malodor measuring apparatus 100 may be extremely high despite the abnormal state of the cooling unit 170 or the operation of the cooling unit 170. In particular, when the internal temperature of the malodor measuring apparatus 100 is high, the sensing value of the sensing unit 130 is often not transmitted to the control unit 110.

The heating unit 175 applies heat to the air provided to the sensing unit 130 to increase the reference air and the measurement air to a predetermined temperature or higher when the temperature of the air supplied to the sensing unit 130 is equal to or less than a predetermined value . When the temperature of the air in contact with the sensing unit 130 is very low, the kinetic energy of the air is low, so that the contact rate in the malodor sensor becomes low, which makes it difficult to obtain an accurate sensing value.

Since the operating object of the cooling unit 170 and the heating unit 175 may be different, the malodor measuring device 100 is preferably divided into at least two housing areas. Preferably, the first housing 101 of at least two of the housing areas includes a control unit 110, a communication unit 120, and a cooling unit 170 to be disconnected from the outside. The first housing 101 may further include a power source unit 190. Preferably, the second housing 102 of at least two of the housing sections has an electromagnetic valve 135, a sensing portion 130, and a heating portion 175 to be shielded from the outside. The second housing 102 may further include at least one of a reference air supply unit 140, a measurement air supply unit 150, a collection unit 180, and a pump 160.

The control unit 110 may control the operation of each part to control the overall operation of the malodor measuring apparatus 100. The control unit 110 may transmit the measured value of the sensing unit 130 to the control device 500 through the communication unit 120. [ The control unit 110 may directly calculate the concentration of the pollutant through the measurement value of the sensing unit 130. [

The power supply unit 190 may receive external power or internal power under the control of the controller 180 and supply power required for operation of the respective components. The power supply unit 190 may reboot the malodor measurement apparatus 100 by a control signal from the control unit 110. To this end, the power supply unit 190 may include a rebooting switch (not shown). The rebooting switch of the power supply unit 190 may be operated by the monitoring device 200, in particular, the monitoring sensing operation unit 230.

4 and 5, the monitoring device 200 includes a monitoring control unit 210, a monitoring device communication unit 220 for performing wired / wireless communication with the control device 500, a monitoring sensing operation unit 230, 290).

The monitoring sensing operation unit 230 can check the status or operation status of each component of the malodor measurement apparatus 100 or can control its operation.

The monitoring sensing operation unit 230 senses whether or not the operation of the control unit 110 of the malodor measurement apparatus 100, the operation of the communication unit 120, the operation of the malodor sensor of the sensing unit 130, Whether or not the reference air switching solenoid valve 146 of the reference air supplying unit 140 is operated, whether the water removing solenoid valve of the measuring air supplying unit 150 is operated, whether the pump 160 is operated, The operating state of the malodor measuring device can be generated by checking whether the malfunction measuring device 180 is operated, whether the cooling unit 170 and the heating unit 175 are operated, and whether the power supply unit 190 is powered.

The monitoring sensing operation unit 230 can measure the temperature inside the first housing 101 and the second housing to generate the part status information of the malodor measuring device.

The component operating state and part state information of the malodor measuring device 100 by the monitoring sensing operation unit 230 may be generated as a message by the control unit and transmitted to the control device 500 through the monitoring device communication unit 220.

The monitoring sensing operation unit 230 is configured to perform the channel switching operation of the electromagnetic valve 135, the channel switching operation of the reference air switching solenoid valve 146 of the reference air supplying unit 140, The operation of the solenoid valve, the operation of the pump 160, the operation of the cooling unit 170 and the heating unit 175, and the operation of the rebooting switch of the power supply unit 190 can be controlled.

The monitoring control unit 210 may control the overall operation of the monitoring device 200 by controlling the operation of each part of the monitoring device 200.

The monitoring device power unit 290 may receive external or internal power under the control of the monitoring controller 210 and supply power necessary for operation of the respective components. It is preferable that the power source of the monitoring device power source unit 290 is independent of the power source of the power source unit 190 of the malodor measurement device 100. If there is an abnormality in the power supply unit 190 of the malodor measuring apparatus 100, the monitoring sensing operation unit 230 should be able to check it.

6 and 7 are flowcharts showing a monitoring method of the monitoring system of the present malodor measuring apparatus. Please refer to Figs. 1 to 5.

6 and 7, the malodor measuring apparatus 100 measures the reference air of the reference air supply unit 140 and the measurement air of the measurement air supply unit 150, and measures each measured reference value and measurement The sensing value may be transmitted to the control apparatus 500 (S710). Each sensing value can be periodically transmitted.

The control apparatus 500 can determine whether the sensed value of the malodor measuring apparatus 100 is in an abnormal range and determine whether the sensed value is abnormal (S715). The case where the sensing value is abnormal, and the case where the reference sensing value and the measurement sensing value are outside the predetermined range, respectively.

If the sensed value of the malodor measuring apparatus 100 is determined to be abnormal, the control apparatus 500 may send an inspection request message to the monitoring apparatus 200 to check each component of the malodor measuring apparatus 100 (S720) .

When the monitoring device 200 receives the inspection request message, the monitoring device 200 determines whether the malodor sensor operation of the sensing part 130 of the malodor measurement device 100, the operation of the electromagnetic valve 135, Whether or not the reference air switching solenoid valve 146 of the air conditioner 140 is operated, whether the moisture removing electromagnetic valve of the measurement air supplier 150 is operating, whether the pump 160 is operating, whether the collecting unit 180 is operating, It is possible to check whether the cooling unit 170 and the heating unit 175 are operated, the measured temperature inside the first housing 101 and the second housing, and whether the power supply unit 190 is powered on or the like (S730).

The checked contents of the monitoring device 200 may be converted into a status information message and transmitted to the monitoring device 500 from the monitoring device 200 (S740).

Upon receiving the status guidance message (S740) from the control apparatus 500, the control apparatus 500 analyzes the status guidance message (S740) and judges whether or not the abnormality can be exited due to the operation of the specific component of the malodor measurement apparatus 100 can do. If the control unit 500 judges that the operation of a specific part is necessary, it processes step A, and if it is determined that the operation of the specific part is not necessary, or if the status abnormality continues despite the operation of the specific part, can do.

First, the process of Step A is as follows. If it is determined that operation of a specific part is necessary in the control apparatus 500, the control apparatus 500 may transmit a message to the malodor measurement apparatus 100 to operate the required part (S830). Examples of the operation of the specific part include a flow path switching operation of the solenoid valve 135 of the malodor measuring apparatus 100, a flow path switching operation of the reference air switching solenoid valve 146 of the reference air supplying unit 140, The operation of the pump 160, the operation of the cooling unit 170 and the heating unit 175, and the operation of the rebooting switch of the power supply unit 190. [ The operation of each part or the selective switching operation can be combined or combined with various conditions such as a sensed value exceeding a predetermined range, an abnormal operation state of each part, and the like. For example, when the reference sensing value is abnormal, the air passage switching of the reference air switching solenoid valve 146 of the reference air supplier 140 is selectively operated so that the air in the odorless air tank 144 is supplied to the solenoid valve 135, And generate a command for forcing the cooling unit 170 to operate.

When the malodor measuring apparatus 100 receives the necessary parts operating message, the malodor measuring apparatus 100 may analyze the message to operate the corresponding parts (S835).

After transmitting the necessary part operation message (S830) and the predetermined time has elapsed, the control device 500 can send a re-check request message to the monitoring device 200 (S840). The malodor measuring apparatus 100 having received the re-check request message checks the status of the malodor measuring apparatus 100 and converts the result of the check into a status guiding message and transmits the status guiding message to the control apparatus 500 (S850). If the state guidance message (S850) includes the contents of the abnormal state of the components of the malodor measurement apparatus 100, the control apparatus 500 generates a message for activating the necessary components of the malodor measurement apparatus 100, (S860). This is because when the malodor measuring apparatus 100 is in an abnormal state and the controller 110 of the malodor measuring apparatus 100 does not properly process the necessary parts operation command, So that a specific part of the measuring apparatus 100 is operated.

The monitoring device 200 having received the required part message can read the message and operate or selectively operate the specific part of the malodor measuring device 100 (S870). Thereafter, the monitoring apparatus 200 may check the status of the malodor measuring apparatus 100, convert the contents of the inspection into a status guidance message, and transmit the status guidance message to the control apparatus 500 (S880).

The control apparatus 500 having received the status guidance message S880 can read the message and determine whether the status of the malodor measurement apparatus 100 is abnormal or normal. If it is determined to be abnormal, step B is processed, and if it is normal, the process according to the abnormal state is terminated. In this specification, if the malodor measuring apparatus 100 is determined to be normal, the process according to the abnormal condition is automatically terminated.

Step B will be described below. As described above, when the state of the malodor measuring apparatus 100 according to the state guidance message S740 can not be switched to the normal state due to the operation of the specific part, or when the specific part has been operated but is in an abnormal state, May generate a reboot message including the reboot command and transmit it to the malodor measurement apparatus 100 (S745).

The malodor measuring apparatus 100 receiving the reboot message S745 may operate the rebooting switch of the power unit 190 to reboot the malodor measuring apparatus 100 (S750).

When the reboot message S745 is transmitted and the predetermined time has elapsed, the control device 500 may transmit a re-check request message to the monitoring device 200 to check the status of the malodor measurement device 100 (S765) . Upon receiving the re-detection request message (S765), the monitoring device 200 may check the status of the malodor measuring device 100 and transmit the status guidance message to the control device 500 based on the checked content (S770).

If the read content of the status guidance message S770 is still abnormal in the state of the malodor measurement apparatus 100, the control apparatus 500 generates a message to cause the malodor measurement apparatus 100 to be rebooted, (S785). This is because the malodor measuring apparatus 100 is in an abnormal state and the malodor measuring apparatus 100 can not properly handle the reboot command by the control unit 110, (100) is forcibly rebooted.

Upon receiving the reboot message S785, the monitoring device 200 may operate the rebooting switch of the malodor measuring device 100 to cause the malodor measuring device 100 to be rebooted (785). Thereafter, the monitoring apparatus 200 may check the status of the malodor measuring apparatus 100, generate a status guidance message, and transmit the status guidance message to the control apparatus 500 (S795). If the status of the malodor measuring apparatus 100 is abnormal even after this procedure, the control apparatus 500 can notify the manager that the self-checking status is not available (S795).

The present invention can also be embodied as computer-readable codes on a computer-readable recording medium. A computer-readable recording medium includes all kinds of recording apparatuses in which data that can be read by a computer system is stored. Examples of the computer-readable recording medium include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like, and may be implemented in the form of a carrier wave (for example, transmission via the Internet) . The computer readable recording medium may also be distributed over a networked computer system so that computer readable code can be stored and executed in a distributed manner.
