When it is determined that the recording timing has arrived and the predetermined time has not elapsed since the control process was started, when the predetermined time has not elapsed since it was determined that the end timing described later has not arrived, and when the predetermined time has not elapsed. If the operation is not accepted, it is determined that the first recording timing has not arrived. Then, when it is determined that the first recording timing has arrived (SA2, Yes), the control unit 57 of the control device 50 activates the fouling degree detection process (SA3), and the first recording timing has not arrived. If it is determined that (SA2, No), the process shifts to SA4. The details of the stain degree detection process will be described later.

The determination may be made based on whether or not a predetermined time has elapsed since then. Here, when the predetermined operation is accepted or when the predetermined time has elapsed, it is determined that the first display timing has arrived, and when the predetermined operation is not accepted or the predetermined time has elapsed. If not, it is determined that the first display timing has not arrived. Then, when it is determined that the first display timing has arrived (SA4, Yes), the control unit 57 of the control device 50 activates the display process (SA5), and determines that the first display timing has not arrived. If it is done (SA4, No), it shifts to SA6. The details of the display processing will be described later.

In the SA6, the control unit 57 of the control device 50 determines whether or not the recording timing (hereinafter referred to as “second recording timing”) for recording the fouling degree history information in the external device (not shown) has arrived. Here, the "external device" means a device or device other than the device constituting the management system 1, and includes, for example, an electric recording medium such as a USB memory or an SD card, a mobile terminal, a management server, and the like. It is a concept. The method for determining whether or not the second recording timing has arrived is arbitrary, but for example, whether or not the external device and the output unit 55 of the control device 50 are directly or indirectly connected. When the external device and the output unit 55 are connected, it is determined that the second recording timing has arrived, and when the external device and the output unit are not connected, the second recording timing is determined. Is determined not to have arrived. Then, when it is determined that the second recording timing has arrived (SA6, Yes), the control unit 57 of the control device 50 activates the recording process (SA7), and determines that the second recording timing has not arrived. If it is done (SA6, No), it shifts to SA8. The details of the recording process will be described later.

In the SA8, the control unit 57 of the control device 50 determines whether or not the timing for ending the control process (hereinafter referred to as “end timing”) has arrived. The method for determining whether or not the end timing has arrived is arbitrary, but for example, a determination is made based on whether or not a predetermined operation has been performed by the administrator via the operation unit 51, and the predetermined operation is performed. If so, it is determined that the end timing has arrived, and if the above predetermined operation is not performed, it is determined that the end timing has not arrived. Then, when it is determined that the end timing has not arrived (SA8, No), the control unit 57 of the control device 50 shifts to SA1, and from SA1 until it is determined by SA8 that the end timing has arrived. The processing of SA8 is repeated. On the other hand, when it is determined that the end timing has arrived (SA8, Yes), the control process is terminated.

(Control process-Fouling degree detection process)
Next, the fouling degree detection process of SA3 in FIG. 5 will be described. FIG. 6 is a flowchart of the stain degree detection process. The fouling degree detection process is a process of detecting and recording the fouling degree of each fire detection device 10.

When the fouling degree detection process is activated, as shown in FIG. 6, in SB1, the control unit 57 of the control device 50 irradiates simulated light from the light emitting unit 20 of each fire detection device 10.

In SB2, the control unit 57 of the control device 50 determines whether or not a light receiving signal has been acquired from each fire detection device 10. Here, the "light receiving signal" is a signal indicating the light receiving amount of the light received by the light receiving unit 30 of the fire detection device 10, and in the embodiment, the light receiving amount information indicating the received light amount and the fire detection device. This will be described as a signal containing identification information. Then, the control unit 57 of the control device 50 waits until it is determined that the received light signal has been acquired (SB2, No), and when it is determined that the received signal has been acquired (SB2, Yes), each fire is detected. After stopping the irradiation of the light emitting unit 20 of the device 10, the process shifts to SB3.

In SB3, the detection unit 57a of the control device 50 detects the degree of contamination of each fire detection device 10 based on the light receiving signal acquired by SB2. The degree of fouling is arbitrary, but for example, the reference value (for example, the measured value measured at the time of shipment from each fire detection device 10) is divided from the light receiving amount of the light receiving amount information included in the light receiving signal. 100 may be integrated into the calculated value, and the integrated value may be detected as the degree of contamination to be detected.

In SB4, the recording control unit 57b of the control device 50 records the degree of contamination detected by SB3 as the degree of contamination history information in the storage unit 58 for each fire detection device identification information. Specifically, the information indicating the degree of fouling detected by SB3, the fire detection device identification information included in the light receiving signal acquired by SB2, the recording order when recording the degree of fouling, the date, and so on. And the information indicating the time are correlated with each other as the pollution degree history information to be recorded (specifically, the pollution degree information, the fire detection device identification information, the recording order information, the recording date information, and the recording time information). And record it in the history DB 58a. After that, the recording control unit 57b of the control device 50 ends the fouling degree detection process and returns to the control process of FIG.

(Control processing-Display processing)
Next, the display process of SA5 in FIG. 5 will be described. FIG. 7 is a flowchart of the display process. The display process is a process of displaying the stain degree history information recorded in the history DB 58a.

When the display process is activated, as shown in FIG. 7, the display designation unit 57d of the control device 50 in SC1 determines whether or not the designation of the display pattern of the stain degree history information has been accepted. Here, the "display pattern of the stain degree history information" means a format for displaying the stain degree history information. In the embodiment, the type of the display pattern of the stain degree history information is the order of recording the degree of stain, the order of high or low degree of stain, and the most recent change amount (for example, the most recently detected amount of change in the degree of stain). The first display pattern and the storage unit 58 are displayed in descending order of the degree of change between the degree of fouling and the degree of fouling detected immediately before the degree of fouling, and in the order of characters of the fire detection device identification information. Of the stain degree history information recorded in, only the stain degree history information selected by a predetermined method (for example, operation by the operation unit 51) and only the stain degree history information corresponding to the stain degree above or below the threshold value. It will be described as including the second display pattern to be displayed.

The method for determining whether or not this display pattern is specified is arbitrary, but for example, a display area (hereinafter, referred to as “display pattern display area”) displayed on the screen of the display unit 54 (hereinafter referred to as “display pattern display area”) is used. Based on whether or not any one of the information generated and displayed in the generated display pattern display area and indicating the display pattern of the pollution degree history information is selected via the operation unit 51. If the above selection is not made, it may be determined that the display pattern designation is not accepted, and if the above selection is made, it may be determined that the display pattern designation is accepted. Then, the display designation unit 57d of the control device 50 waits until the designation of the display pattern is accepted (SC1, No), and when it is determined that the designation of the display pattern is accepted (SC1, Yes), the acceptance is received. After specifying the displayed display pattern, the process shifts to SC2.

In SC2, the display control unit 57c of the control device 50 causes the display unit 54 to display the pollution degree history information recorded in the history DB 58a in the display pattern specified by SC1. The method of displaying the pollution degree history information is arbitrary, but for example, a display area (hereinafter referred to as “history display area”) (hereinafter referred to as “history display area”) displayed on the screen of the display unit 54 is generated, and the generated history is generated. It is a display pattern in which the pollution degree history information (specifically, recording order information, recording date information, recording time information, fire detection device identification information, and pollution degree information) is specified in the display area by SC1. Moreover, it may be displayed in a tabular format. As an example, when a pattern to be displayed side by side in the recording order of display pattern = stain degree is specified in SC1, the stain degree history information is displayed in the history display area with the display pattern as shown in FIG.

By such processing of SC1 and SC2, it is possible to present the pollution degree history information as compared with the conventional technique (the technique of displaying only the information indicating the current dimming rate). Therefore, the administrator can easily grasp the background of the progress of the fouling of the fire detection device 10, and it is possible to improve the manageability of the fire detection device 10. Further, since the stain degree history information can be displayed in the display pattern designated by the display designation unit 57d, the stain degree history information can be displayed according to the needs of the administrator, and the fire detection device 10 is polluted. It will be easier for the administrator to understand the circumstances of the fire.

Returning to FIG. 7, in SC3, the display control unit 57c of the control device 50 determines whether or not the display timing (hereinafter, referred to as “second display timing”) for displaying the stain timing described later has arrived. The method for determining whether or not the second display timing has arrived is arbitrary, but for example, it may be determined based on whether or not a predetermined operation has been accepted via the operation unit 51 within a predetermined time. Judgment is made based on whether or not a predetermined cycle (for example, half a year, one year, etc.) has elapsed (the same applies to the processing of SC6 described later). Here, when the predetermined operation is accepted or when the predetermined cycle has elapsed, it is determined that the second display timing has arrived, and when the predetermined operation is not accepted or the predetermined cycle has not elapsed. In that case, it is determined that the second display timing has not arrived. Then, the display control unit 57c of the control device 50 shifts to SC4 when it is determined that the second display timing has arrived (SC3, Yes), and when it is determined that the second display timing has not arrived. (SC3, No) shifts to SC6.

In the SC4, the estimation unit 57f of the control device 50 determines the timing at which the degree of contamination of the fire detection device 10 specified by the predetermined method becomes equal to or higher than the threshold value based on the contamination degree history information recorded in the history DB 58a (hereinafter, “staining timing”). ") Is estimated.

The method for estimating the fouling timing is arbitrary, but for example, it may be estimated as follows. That is, first, the administrator performs a predetermined operation via the operation unit 51 to extract the pollution degree history information corresponding to the fire detection device 10 to be estimated from the pollution degree history information recorded in the history DB 58a. .. Next, based on the recording date information, the recording time information, and the fouling degree information included in the above-extracted fouling degree history information, the change rate of the fouling degree for each predetermined time is calculated, and the calculated change rate is obtained. (More specifically, the average value is calculated after removing the rate of change in the degree of contamination that shows a negative value). Next, the most recently recorded fouling degree information is extracted from the fouling degree information included in the above-extracted fouling degree history information. Then, the average value of the rate of change calculated above is divided from the value obtained by subtracting the pollution degree of the extracted pollution degree information from the threshold value, and the divided value is estimated as the pollution timing to be estimated.

In the SC5, the display control unit 57c of the control device 50 causes the display unit 54 to display the stain timing estimated by the SC4 and the fire detection device identification information corresponding to the stain timing in association with each other. Here, the method of displaying the fouling timing and the fire detection device identification information is arbitrary, but for example, a display area (hereinafter, referred to as “estimated display area”) displayed on the screen of the display unit 54 (hereinafter referred to as “estimated display area”) is generated. Then, the information indicating the fouling timing and the fire detection device identification information may be displayed adjacent to each other in the generated estimated display area.

By such processing of SC4 and SC5, the pollution timing of the specific fire detection device 10 can be presented, and for example, the fire detection device 10 is managed before the degree of pollution of the specific fire detection device 10 becomes equal to or higher than the threshold value. It will be possible for a person to take measures related to cleaning.

In the SC6, the display control unit 57c of the control device 50 determines whether or not the display timing (hereinafter, referred to as “third display timing”) for displaying the zero number of times, which will be described later, has arrived. Then, the display control unit 57c of the control device 50 shifts to SC7 when it is determined that the third display timing has arrived (SC6, Yes), and when it is determined that the third display timing has not arrived. (SC6, No) ends the display process and returns to the control process of FIG.

Returning to FIG. 7, in SC7, the specific unit 57g of the control device 50 is the number of times when the pollution degree of each of the plurality of fire detection devices 10 becomes a zero value based on the pollution degree history information recorded in the history DB 58a (hereinafter). , Called "zero times").

The method for specifying the zero number of times is arbitrary, but may be specified as follows, for example. That is, first, from the pollution degree information included in the pollution degree history information recorded in the history DB 58a, the pollution degree information indicating a zero value is extracted for each fire detection device identification information. Then, the total number of stain degree information indicating the extracted zero value is calculated for each fire detection device identification information, and the calculated total number is specified as the number of zeros to be specified.

In the SC8, the display control unit 57c of the control device 50 causes the display unit 54 to display the zero number of times specified by the SC7 and the fire detection device identification information corresponding to the zero number of times in association with each other, and then performs the display process. After finishing, the process returns to the control process of FIG. Here, the zero number of times and the display method of the fire detection device identification information are arbitrary, but for example, a display area (hereinafter referred to as "specific display area") displayed on the screen of the display unit 54 is generated. Then, in the generated specific display area, the information indicating the number of times of zero and the fire detection device identification information may be displayed adjacent to each other and displayed in a tabular format.

By such processing of SC7 and SC8, the zero number of times of each fire detection device 10 can be presented. (Shortening the replacement cycle, etc.) can be taken.

(Control processing-Recording processing)
Next, the recording process of SA7 in FIG. 5 will be described. FIG. 8 is a flowchart of the recording process. The recording process is a process of recording the fouling degree history information recorded in the history DB 58a in an external device.

When the recording process is started, as shown in FIG. 8, the recording designation unit 57e of the control device 50 in SD1 determines whether or not the designation of the recording pattern of the fouling degree history information has been accepted. Here, the "recording pattern of the stain degree history information" means a format for recording the stain degree history information. In the embodiment, the types of the recording pattern of the stain degree history information are, in the order of recording the degree of stain, the order of high or low degree of stain, the order of the most recent change in the amount of change of the degree of stain, or the order of small amount. The pollution degree selected by a predetermined method (for example, operation by the operation unit 51) among the first recording pattern for recording the fire detection device identification information in character order and the pollution degree history information recorded in the storage unit 58. It will be described as including only the history information and the second recording pattern for recording only the pollution degree history information corresponding to the pollution degree above or below the threshold value.

The method for determining whether or not this recording pattern is specified is arbitrary, but for example, a display area (hereinafter, referred to as “recording pattern display area”) displayed on the screen of the display unit 54 (hereinafter referred to as “recording pattern display area”) is used. Based on whether or not any one of the information generated and displayed in the generated recording pattern display area and indicating the recording pattern of the pollution degree history information is selected via the operation unit 51. If the above selection is not made, it may be determined that the recording pattern designation is not accepted, and if the above selection is made, it may be determined that the recording pattern designation is accepted. Then, the recording designation unit 57e of the control device 50 waits until the designation of the recording pattern is accepted (SD1, No), and when it is determined that the designation of the recording pattern is accepted (SD1, Yes), the acceptance is received. After specifying the recorded recording pattern, the process shifts to SD2.

In SD2, the recording control unit 57b of the control device 50 causes an external device to record the pollution degree history information recorded in the history DB 58a with the recording pattern specified in SD1. The method of recording the pollution degree history information is arbitrary, but for example, a file for recording the pollution degree history information (hereinafter referred to as "first recording file") is created, and the created first recording file is created. After recording the fouling degree history information in the recording pattern specified by SD1, the first recording file is recorded by being output to an external device by the output unit 55. As an example, when a pattern for recording in the order of recording pattern = contamination degree is specified in SD1, the contamination degree history information is recorded in the external device in the recording pattern as shown in FIG.

By such processing of SD1 and SD2, the stain degree history information can be provided to the external device, and for example, a detailed analysis process of the stain degree history information can be easily performed by using a processing device outside the management system 1. .. Therefore, it is possible to improve the convenience of the administrator in using the management system 1. Further, since the stain degree history information can be recorded in the recording pattern designated by the record designation unit 57e, the stain degree history information can be provided to the external device in the recording pattern according to the needs of the administrator. For example, the management system 1 It is possible to save the trouble of changing the recording pattern of the pollution degree history information in the external processing device.

Returning to FIG. 8, in the SD3, the recording control unit 57b of the control device 50 determines whether or not the recording timing (hereinafter, referred to as “third recording timing”) for recording the contamination timing described later has arrived. The method for determining whether or not the third recording timing has arrived is arbitrary, but for example, it may be determined based on whether or not a predetermined operation is accepted via the operation unit 51 within a predetermined time (. The same applies to the SD6 processing described later). Here, when the predetermined operation is accepted, it is determined that the third recording timing has arrived, and when the predetermined operation is not accepted, it is determined that the third recording timing has not arrived. Then, the recording control unit 57b of the control device 50 shifts to SD4 when it is determined that the third recording timing has arrived (SD3, Yes), and when it is determined that the third recording timing has not arrived. (SD3, No) shifts to SD6.

In SD4, the estimation unit 57f of the control device 50 estimates the fouling timing based on the fouling degree history information recorded in the history DB 58a. The method for estimating the fouling timing is arbitrary, but for example, when the fouling timing is estimated by SC4 of the display process performed immediately before the recording process, the fouling timing should be estimated as the fouling timing. You may estimate. On the other hand, if the SC4 process is not performed in the display process performed immediately before the recording process, or if the display process is not performed immediately before the recording process, the fouling timing is determined by the same method as the SC4. May be estimated.

In the SD5, the recording control unit 57b of the control device 50 causes the external device to record the fouling timing estimated by the SD4 and the fire detection device identification information corresponding to the fouling timing in association with each other. Here, the method of recording the fouling timing and the fire detection device identification information is arbitrary, but for example, a file for recording the fouling timing and the fire detection device identification information (hereinafter referred to as "second recording file") is used. It is created, and after recording the information indicating the fouling timing and the fire detection device identification information in the created second recording file, the second recording file is recorded by being output to an external device by the output unit 55.

By such processing of SD4 and SD5, the fouling timing of the specific fire detection device 10 can be provided to the external device. For example, it is troublesome to calculate the fouling timing of the specific fire detection device 10 in the treatment device outside the management system 1. Can be omitted.

In the SD6, the recording control unit 57b of the control device 50 determines whether or not the recording timing for recording the zero number of times (hereinafter referred to as “fourth recording timing”) has arrived. Then, the recording control unit 57b of the control device 50 shifts to SD7 when it is determined that the fourth recording timing has arrived (SD6, Yes), and when it is determined that the fourth recording timing has not arrived. (SD6, No) ends the recording process and returns to the control process of FIG.

Returning to FIG. 8, in SD7, the identification unit 57g of the control device 50 identifies the zero number of times of each of the plurality of fire detection devices 10 based on the pollution degree history information recorded in the history DB 58a. The method of specifying the zero number of times is arbitrary, but for example, when the zero number of times is specified by SC7 of the display process performed immediately before the recording process, the zero number of times should be specified as the zero number of times. It may be specified. On the other hand, if the SC7 process is not performed in the display process performed immediately before the recording process, or if the display process is not performed immediately before the recording process, the zero number of times is used in the same manner as the SC7. May be specified.

In the SD8, the recording control unit 57b of the control device 50 causes the external device to record the zero number of times specified by the SD7 and the fire detection device identification information corresponding to the zero number of times in association with each other, and then ends the recording process. Then, the process returns to the control process of FIG. Here, the method of recording the zero number of times and the fire detection device identification information is arbitrary, but for example, a file for recording the zero number of times and the fire detection device identification information (hereinafter referred to as "third recording file") is used. It is created, and after recording the information indicating the number of times of zero and the fire detection device identification information in the created third recording file, the third recording file is recorded by being output to an external device by the output unit 55.

By such processing of SD7 and SD8, the zero number of times of each fire detection device 10 can be provided to the external device, and for example, the trouble of calculating the zero number of times of each fire detection device 10 in the processing device outside the management system 1 can be omitted. can.

It is selected by a predetermined method from the first recording pattern for recording in the order of the most recent change amount in the order of the largest or the smallest , or in the character order of the fire detection device identification information, or the pollution degree history information recorded in the storage unit 58. Since it includes a second recording pattern that records only the fouling degree history information or only the fouling degree history information corresponding to the fouling degree above or below the threshold value, the fouling degree history information is externally recorded with a recording pattern according to the user's needs. It can be further provided to the apparatus, and for example, the trouble of changing the recording pattern of the pollution degree history information in the processing apparatus outside the management system 1 can be further omitted.

Judgment is made based on whether the cycle of the fluctuation cycle that becomes equal to or higher than the threshold value is shorter than the predetermined value, or is determined based on whether the fluctuation amount of the degree of contamination within the predetermined period is smaller than the predetermined value. .. Then, when the cycle of the fluctuation cycle is shorter than the predetermined value or the fluctuation amount is smaller than the predetermined value, it is determined that the abnormality may have occurred, and the cycle of the fluctuation cycle is the predetermined value. If it is not shorter than, or if the fluctuation amount is not smaller than the predetermined value, it is determined that there is no possibility that the abnormality has occurred. By such processing, it is possible to provide an external device that an abnormality may have occurred in any of the plurality of fire detection devices, for example, any of the plurality of fire detection devices in the processing device outside the management system. It is possible to save the trouble of identifying the possibility that an abnormality has occurred. In this case, for example, when a predetermined operation is received via the operation unit 51, the recording control unit 57b of the control device 50 specifies the number of repetitions of the fluctuation cycle, and then the specification is made. The pollution degree history information recorded in the history DB 58a may be recorded in the external device in descending order of the number of repetitions.
