Detailed Description
Hereinafter, a passenger conveyor according to an embodiment of the present invention will be described with reference to the drawings.
[ embodiment 1]
An escalator 10 according to embodiment 1 will be described with reference to fig. 1 to 5. In the present embodiment, the escalator 10 will be described as a passenger conveyor.
(1) Escalator 10
The structure of the escalator 10 is explained with reference to fig. 1 and 2.
As shown in fig. 1, a truss 12 is erected in a building 1 such as an airport. The interior of the upper-layer-side end of the truss 12 is a machine room 14, and a drive device 16 and a control unit 18 are provided. Upper and lower step boards (i.e., leading boards of an escalator) 20 and 22 are provided on the upper and lower sides of the truss 12, respectively, and have the same height as the floor of the building 1.
A plurality of steps 24 connected in a ring shape are arranged inside the truss 12, and travel at a predetermined travel speed by the drive device 16. A pair of left and right balustrades 26, 26 are provided upright on the upper portion of the truss 12 on both left and right sides of the step 24. These balustrades 26, 26 are constituted by glass panels. A handrail rail 28 shown in fig. 2 is provided on an upper portion of each balustrade 26, and a handrail belt 30 travels on the handrail rail 28. The handrail belt 30 travels by the drive device 16 in synchronization with the steps 24.
As shown in fig. 1 and 2, a skirt board 32 is vertically erected on the base portion of the inner side (i.e., the step 24 side) of each balustrade 26, and an inner ledge 34 is provided to be inclined from the upper end of the skirt board 32 toward the balustrade 26. On the other hand, an outer decking 36 is provided on the outside of the balustrade 26 and at the base of the balustrade 26. The skirt panels 32, the inner wall frames 34, and the outer decking 36 are fixed to the truss 12, respectively.
As shown in fig. 1 and 2, a plurality of posts 38 having substantially the same height as the balustrade 26 are provided on the upper surface of the outer cover 36 at equal intervals. In the present embodiment, 6 columns 38 are provided vertically as an example, and the columns are referred to as a 1 st column 38-1, a 2 nd column 38-2, and … … th 6 th column 38-6 in this order from the upper layer side. The expression "column 38" is a case where 6 columns are collectively referred to. As shown in fig. 1 and 2, an upper body temperature sensor 40 is provided at an upper portion of the pillar 38 in a direction toward the step 24, and a middle body temperature sensor 42 is provided at a central portion in a direction toward the step 24. As shown in fig. 2, a lower body temperature sensor 44 is provided on the inner wall frame 34 corresponding to the position of each column 38. These body temperature sensors 40, 42, 44 are infrared sensors. The upper body temperature sensor 40, the middle body temperature sensor 42, and the lower body temperature sensor 44 located at the same position are collectively referred to as a group, and are set as a 1 st group, a 2 nd group, … …, and a 6 th group in order from the upper layer side.
(2) Electrical structure of escalator 10
The electrical structure of the escalator 10 will be described with reference to fig. 3. The driving device 16, the upper body temperature sensor 40, the middle body temperature sensor 42, and the lower body temperature sensor 44 provided in each column 38 are connected to the control unit 18. The control unit 18 is connected to a management company of the escalator 10, a quarantine mechanism, a communication unit 46 for communicating with a smartphone, which is a communication device of each passenger, and a storage unit 48.
(3) Operation states of the body temperature sensors 40, 42, 44
Next, the case where the body temperature sensors 40, 42, 44 measure the body temperature of the passenger will be described with reference to the block diagrams of fig. 1, 2, 3, and the flowcharts of fig. 4 and 5. In this description, the following are assumed: the steps 24 of the escalator 10 are moved down, and passengers get on the escalator from the upper and lower step plates 20 on the upper-stage side of the escalator 10 as shown in fig. 1, and stand on the steps 24 to go to the lower stage as shown in fig. 2.
First, the processing when the passenger passes through the position of the 1 st column 38-1 of the 1 st group as shown in fig. 2 will be described with reference to the flowchart of fig. 4.
In step S1, when the passenger riding on the steps 24 passes through the 1 st column 38-1 position of the 1 st group, the upper body temperature sensor 40, the middle body temperature sensor 42, and the lower body temperature sensor 44 simultaneously measure the body temperature of the passenger as shown in fig. 2, and the process proceeds to step S2.
In step S2, since the body temperature is measured to be low after the passage of the passenger and the body temperature is measured not to be low during the passage, it is determined that the passenger has passed when the measured body temperature is lower than a predetermined minimum body temperature (for example, 34 ℃), the process proceeds to step S3, and it is determined that the passenger has passed when the measured body temperature is not lower than the minimum body temperature, and the measurement of the body temperature is continued.
In step S3, the control unit 18 calculates an average body temperature of the highest body temperature measured by the upper body temperature sensor 40, the highest body temperature measured by the middle body temperature sensor 42, and the highest body temperature measured by the lower body temperature sensor 44 of the 1 st group, and the process proceeds to step S4. The reason why the highest body temperature is averaged in this way is that the highest temperature is taken as the body temperature of the passenger because the measured temperature gradually rises and then falls when the passenger moves by the step 24. The average of the upper, middle and lower body temperatures is taken to minimize measurement errors.
After one passenger passes through step S4, the body temperatures measured by the upper body temperature sensor 40, the middle body temperature sensor 42, and the lower body temperature sensor 44 are all reset, and the process returns to step S1 to measure the body temperature of the next passenger.
The upper body temperature sensor 40, the middle body temperature sensor 42, and the lower body temperature sensor 44 of the groups 2 to 5 are also processed in the same manner as the process of the flowchart of fig. 4, and the body temperatures of the passengers are measured.
Next, the processing in the case where the control unit 18 determines whether the body temperature of one passenger is high will be described with reference to the flowchart of fig. 5.
In step S11, the control unit 18 calculates the average body temperature of the body temperatures measured by the upper body temperature sensor 40, the middle body temperature sensor 42, and the lower body temperature sensor 44 belonging to the group 1, and the process proceeds to step S12.
In step S12, the control unit 18 adds an identifier to the average body temperature of group 1 and stores the identifier in the storage unit 48 shown in fig. 3. Then, the process proceeds to step S13. Here, the "identifier" is given to identify which passenger has the average body temperature.
In step S13, the control unit 18 substitutes 2 for the group number k, and proceeds to step S14 when a seconds have elapsed, and continues the state when a seconds have not elapsed. This waiting for the passage of a seconds is to take into account the time required for the passenger to ride on the steps 24 to move from the position of the 1 st column 38-1 of the 1 st group to the position of the 2 nd column 38-2 of the 2 nd group. As shown in fig. 1, when the distance from the 1 st column 38-1 of the 1 st group to the 2 nd column 38-2 of the 2 nd group is L and the travel speed is V, a is L/V.
In step S14, the average body temperature of the kth group is stored in the storage unit 48. For example, when a second has elapsed from the position of group 1, the same passenger has moved to the position of group 2, and therefore the average body temperature of group 2 at that time is calculated. This enables the body temperature of the same passenger to be measured twice. Then, the process proceeds to step S15.
In step S15, since the passenger is the same person, the controller 18 stores the average body temperature of the kth group (for example, the 2 nd group) in the storage unit 48 shown in fig. 3 in association with the identifier assigned to the 1 st group, and proceeds to step S16. Thus, the average body temperatures of the respective groups are associated with the identifiers of the same passenger.
In step S16, if the group number k is 6, the process proceeds to step S19 (yes), and if the group number k is less than 6, the process proceeds to step S17 (no).
In step S17, the control unit 18 sets the group number k to k +1, and proceeds to step S18. This processing is performed to assign the same identifier to each of the average body temperatures from group 2 to group 6 in the same manner.
In step S18, the control unit 18 waits for a seconds to elapse again. This is to take into account the time required for the same passenger to move to the position of the next group. And then returns to step S14.
In step S19, the control unit 18 calculates the total average body temperature of the average body temperatures of the 1 st to 6 th groups of passengers to which the same identifier is assigned. Then, the process proceeds to step S20.
In step S20, if the total average body temperature of the passengers assigned with the same identifier is higher than the reference body temperature, the controller 18 proceeds to step S22, and if the total average body temperature is equal to or lower than the reference body temperature, the controller proceeds to step S21. The reference body temperature is, for example, 37 ℃ which is a boundary of whether or not a disease is present.
In step S21, since the total average body temperature of the passengers given the same identifier is equal to or lower than the reference body temperature, the control unit 18 determines that the passengers are not in a disease, resets all the data, and ends the process.
In step S22, since the total average body temperature of the passengers given the same identifier is higher than the reference body temperature, the control unit 18 transmits a warning signal to the outside via the communication unit 46 shown in fig. 3. The destination of the transmission is a management company, a quarantine organization, or a medical organization that manages the building.
(4) Fruit extract
According to the present embodiment, when the total average body temperature of the passenger is higher than the reference body temperature, the warning signal is transmitted to the outside, and the presence of the passenger suffering from the disease can be notified.
In addition, when the body temperature of the passenger is measured, the average body temperature of the body temperatures measured by the 3- unit temperature sensors 40, 42, and 44 in the upper-lower direction is calculated, and therefore, errors can be reduced.
Further, since the average body temperature is measured 6 times for the same passenger according to the traveling speed of the step 24, the total average body temperature, which is the average value, is calculated and compared with the reference body temperature, the body temperature of the passenger can be measured more accurately.
[ embodiment 2]
Next, embodiment 2 will be explained. In embodiment 1, the object to be notified to the outside is a management company, a quarantine organization, or a medical organization of the escalator 10, but instead, in the present embodiment, a communication device such as a smartphone is transmitted to a passenger.
First, the passenger installs an application in his smartphone, at which time an identifier (e.g., ID) and a mail address are registered. The application is the following software: when a passenger is mounted on the escalator 10, an identifier is transmitted to the communication unit 46 in response to a search signal from the communication unit 46 of the control unit 18, and the total average body temperature or a warning message of the passenger is received from the control unit 18 and displayed on the display unit. On the other hand, when the application is installed in the passenger's smartphone, the control unit 18 registers the identifier and mail address of the passenger smartphone in the storage unit 48. The storage location is not limited to the storage unit 48, and may be a storage unit of a computer of a management company.
Next, the control unit 18 always transmits a search signal from the communication unit 46.
When a passenger is mounted on the escalator 10, the smartphone of the passenger transmits its own identifier to the communication unit 46 of the control unit 18 in response to the search signal, and the communication unit 46 receives the identifier.
Next, the control unit 18 measures the body temperature of the passenger and calculates the total average body temperature by the method described in embodiment 1.
Next, the control unit 18 transmits the total average body temperature of the passenger to the mail address corresponding to the received identifier, and also transmits a warning message as a warning signal when the body temperature is higher than the reference body temperature.
Thus, the passenger can know his or her body temperature (total average body temperature) and that his or her body temperature is higher than the reference body temperature by watching the smartphone.
In addition, when the warning signal is transmitted to the smartphone, the position information of the medical institution within a predetermined radius (for example, within 1km radius) from the installation position of the escalator 10 may be transmitted.
[ embodiment 3]
Next, embodiment 3 will be explained. In the present embodiment, in addition to the configuration of embodiment 1, a camera is provided in the escalator 10 or the building 1, and the camera is connected to the control unit 18.
First, the camera takes an image of the face of the passenger passing through the 1 st post 38-1.
Next, the control unit 18 associates the same identifier with the above-mentioned image and stores the image in the storage unit 48, in addition to the average body temperature of the groups 1 to 6.
Next, when the total average body temperature is higher than the reference body temperature, the control unit 18 transmits a warning signal including the image of the face to a medical institution or a quarantine institution.
Therefore, the medical institution and the quarantine institution can judge the person above the reference body temperature at a glance by watching the image.

In the above embodiments, a plurality of body temperature sensors are provided along the traveling direction of the steps 24, but the present invention is not limited thereto, and only one body temperature sensor may be provided.
In the above embodiment, the lower body temperature sensor 44 is provided at the inner ledge 34, but may be provided at the skirt board 32 instead.
In the above embodiment, since the balustrade 26 has a glass panel structure, the column 38 is erected on the outer cover 36, and the upper body temperature sensor 40 and the middle body temperature sensor 42 are provided, but when the balustrade 26 is a metal panel, the upper body temperature sensor 40 and the middle body temperature sensor 42 may be provided on the metal panel of the balustrade 26.
