Description

The present invention relates to a radio wave measurement system, and is suitable for application to, for example, a radio wave measurement system for measuring radio waves received by a wireless communication device installed in a machine room of a passenger conveyor.

Conventionally, as an escalator operation monitoring device, monitoring data indicating the operation status of an escalator is transmitted to a device in a control room by a radio signal, and the signal received by the device in the control room is transmitted to a device in a monitoring station using a telephone line. This is done so that a professional worker can accurately grasp the driving situation.

When the escalator breaks down, there is an advantage that the administrator does not have to report the situation of the breakdown to the maintenance company, and the maintenance company has the advantage that the cause of the breakdown can be quickly confirmed.

However, it was not possible to restore the escalator to normal operation without waiting for the dispatch of workers from the maintenance company, and a prompt restoration could not be expected. Furthermore, in order to send the monitoring data to the equipment of the monitoring station, it is necessary to construct communication equipment in each route from the escalator to the equipment in the control room and from the equipment in the control room to the equipment in the monitoring station.

In this respect, the maintenance company can immediately grasp the operation status, and by using wireless communication, it is possible to eliminate the construction of communication equipment for communication between the equipment in the control room and the equipment in the monitoring station during wired communication. An escalator operation monitoring device is known that can immediately resume operation in response to remote control from a station device (see Patent Document 1).

JP-A-9-278336

The technique described in Patent Literature 1 can be used in an environment in which wireless communication can be stably performed. In an environment where communication is unstable or in which communication cannot be connected, it is not possible to produce results as planned. Therefore, before installing a wireless communication device, it is necessary to investigate and measure whether the environment allows wireless communication, and it is necessary to measure in an environment where wireless communication is actually performed.

However, the environment in which radio waves are measured differs depending on the operator, and if radio waves cannot be measured under correct conditions, communication may not be possible during operation. In this case, the operator has to go to the site to investigate the cause, re-measure, etc., and it takes time to respond.

The present invention has been made in consideration of the above points, and intends to propose a radio wave measurement system capable of reducing variations in the environment when radio waves are measured by an operator.

In order to solve such problems, the present invention provides a radio wave measuring system for measuring radio waves received by a wireless communication device provided in a machine room of a passenger conveyor, which is provided in the machine room and opens and closes the machine room. a first sensor for detecting an opening/closing member for the passenger conveyor; a second sensor provided in the machine room for detecting an operating state of the passenger conveyor; and a sensor value of the first sensor. a measurement processing unit that determines whether or not the opening and closing member is closed based on the sensor value of the second sensor, and determines whether or not the passenger conveyor is operating based on the sensor value of the second sensor; When it is determined that the opening/closing member is closed and the passenger conveyor is in operation, it is determined that the conditions for measuring radio waves are satisfied.

In the above configuration, for example, it is determined that the conditions for measuring radio waves are satisfied, so it is possible to avoid a situation in which radio waves are measured under erroneous conditions. In addition, for example, since the system uniformly determines whether the conditions for radio wave measurement are satisfied, differences in the environment in which radio waves are measured by workers can lead to poor communication during operation, requiring investigation of the cause. It is possible to reduce the number of cases where

FIG. 3 shows the work procedure (radio wave measurement procedure) of a worker involved in diagnosing whether the environment allows wireless communication, and the process of measuring radio waves related to diagnosing whether the environment allows wireless communication (radio wave measurement). and processing).

The operator installs the radio wave measuring device 130 and the wireless communication device 140 in the lower machine room 150 (step S301). More specifically, when the worker arrives at the site where the passenger conveyor 110 is installed, the worker installs a safety fence, stops the passenger conveyor 110, removes the cover plate 160 of the lower machine room 150, and removes the radio wave measuring device. 130 and the wireless communication device 140 are installed, the radio wave measuring device 130 and the wireless communication device 140 are connected, and the radio wave measuring device 130 is activated.

In step S302, the radio wave measuring device 130 is activated in response to the operator's operation.

In step S<b>305 , the radio wave measuring device 130 transmits an activation instruction to the wireless communication device 140 . The wireless communication device 140 is activated in response to the above instruction from the radio wave measuring device 130 and measures radio waves. The radio wave measurement device 130 receives the measurement data measured by the wireless communication device 140 and stores it in the radio wave measurement value 205 .

In step S306, the operator attaches the cover plate 160. FIG.

At step S307, the operator starts the passenger conveyor 110. FIG.

In step S308, the radio wave measuring device 130 reads the illuminance sensor value 203 and determines whether or not the illuminance sensor value 203 has decreased by a certain amount or more. If the radio wave measuring device 130 determines that the illuminance sensor value 203 has decreased by a certain amount or more, the process proceeds to step S309, and if it is determined that the illuminance sensor value 203 has not decreased by a certain amount or more, the process returns to step S308.

In step S309, the radio wave measuring device 130 reads the magnetic sensor value 204 and determines whether or not the waveform of the magnetic sensor value 204 has a constant cycle. If it is determined that the waveform of the magnetic sensor value 204 has a constant period, the process proceeds to step S310, and if it is determined that the waveform of the magnetic sensor value 204 has not a constant period, the process returns to step S308.

In other words, when the cover plate 160 is not properly (normally) attached, or when the step 120 is not properly (normally) operating, the illuminance sensor value 203 and the magnetic sensor value 204 are read again. . If the cover plate 160 is properly attached and the steps 120 are properly operating, it is determined that the radio wave measurement conditions are satisfied, and the process proceeds to step S310.

In step S310, the radio wave measurement device 130 outputs from the speaker 209 a start sound indicating the start of radio wave measurement necessary for diagnosing whether the environment is in which wireless communication is possible. Hereinafter, the time when the measurement of the radio waves is started is referred to as "measurement start time". Note that the wireless communication device installed in the lower machine room 150 is not limited to the wireless communication device 140 actually used for diagnosis.

In step S311, the radio wave measuring device 130 refers to the illuminance sensor value 203 and determines whether or not the illuminance sensor value 203 has increased by a certain value due to the opening of the cover plate 160 or the like. If the radio wave measuring device 130 determines that the illuminance sensor value 203 has increased by a constant value, the process proceeds to step S315, and if it determines that the illuminance sensor value 203 has not increased by a constant value, the process proceeds to step S312.

In step S312, the radio wave measuring device 130 refers to the magnetic sensor value 204 and determines whether or not the waveform of the magnetic sensor value 204 has been disturbed due to, for example, the passenger conveyor 110 being stopped. If the radio wave measuring device 130 determines that the waveform of the magnetic sensor value 204 is disturbed, the process proceeds to step S315, and if it is determined that the waveform of the magnetic sensor value 204 is not disturbed, the process proceeds to step S313.

In step S313, the radio wave measuring device 130 determines whether or not a certain amount of time has passed since the measurement was started. If the radio wave measuring device 130 determines that a certain amount of time has passed since the start of measurement, the process proceeds to step S314, and if it is determined that the certain period of time has not elapsed since the start of measurement, the process proceeds to step S311. return. Hereinafter, the point in time after a certain period of time has elapsed from the start of measurement will be referred to as the "end point of measurement." Also, the period from the start of measurement to the end of measurement (the fixed time described above) is referred to as a "measurement period."

In step S314, the speaker 209 outputs an end sound (normal end sound) indicating normal termination from the speaker 209, and ends the radio wave measurement process.

In step S315, the speaker 209 outputs abnormal termination as an end sound (abnormal end sound) from the speaker 209, and ends the radio wave measurement process.

FIG. 4 is a diagram schematically showing time-series changes in the radio wave measurement value 205 (radio wave intensity), the illuminance sensor value 203, the magnetic sensor value 204, and the speed of the passenger conveyor 110 (passenger conveyor speed). .

(A) Period 400 before cover plate attachment
Since the cover plate 160 is open at the start of diagnosis, the radio wave measurement value graph 410 is relatively high, and the illuminance sensor value graph 420 is also relatively high.

(B) Cover plate closing work period 401
By closing the cover plate 160, the values of the radio wave measurement value graph 410 and the illuminance sensor value graph 420 are lowered. In this example, since the cover plate 160 is closed while being shifted, the values of the radio wave measurement value graph 410 and the illuminance sensor value graph 420 decrease according to the closing ratio.

Also, since the cover plate 160 is configured to contain a magnetic material such as iron, the amount of magnetism increases according to the rate at which the cover plate 160 is closed, and the value of the magnetic sensor value graph 430 also increases.

(C) Passenger conveyor start time 402
When the passenger conveyor 110 operates, the steps 120 operate and the magnetic sensor value graph 430 changes periodically. As the speed of the step 120 increases, the period of the waveform of the magnetic sensor value graph 430 becomes shorter, and when the speed of the step 120 reaches the rated speed, the period of the waveform of the magnetic sensor value graph 430 becomes constant.

Moreover, the passenger conveyor speed graph 440 indicates that the passenger conveyor speed increases after the passenger conveyor 110 starts operating until it reaches the rated speed.

(D) Measurement start point 403
It was determined that the value of the illuminance sensor value graph 420 decreased to the threshold value 421 (the cover plate 160 was properly closed), and the waveform of the magnetic sensor value graph 430 became constant (the passenger conveyor 110 was properly operated). ), the start sound is output from the speaker 209 .

Whether the cover plate 160 has been properly closed may be determined by the values of the magnetic sensor value graph 430 . In this case, the radio wave measuring device 130 determines whether or not the value of the magnetic sensor value graph 430 has increased to a constant value and is constant. The radio wave measuring device 130 determines that the cover plate 160 has been properly closed when the value of the magnetic sensor value graph 430 rises to a constant value and remains constant. Whether or not the cover plate 160 is properly closed may be determined based on the values of the illuminance sensor value graph 420, the values of the magnetic sensor value graph 430, or both values. can be determined. For example, when the radio wave measuring device 130 detects that the cover plate 160 is closed from the illuminance sensor value 203 and that the cover plate 160 is closed from the magnetic sensor value 204, the cover plate 160 is You may determine that it is closed.

(E) Measurement period 404
Radio waves are measured for a certain period of time (measurement period 404). In the measurement period 404, when it is determined that the value of the illuminance sensor value graph 420 has increased by a constant value above the threshold value 421, the radio wave measurement is terminated, and the speaker 209 outputs an abnormal termination sound. Note that when it is determined that the value of the illuminance sensor value graph 420 has dropped below the threshold value 421 by a constant value, the radio wave measurement is continued.

Further, when it is determined that the period of the waveform of the magnetic sensor value graph 430 is disturbed (for example, the period of the waveform is lengthened) in the measurement period 404, the measurement of radio waves is terminated, and an abnormal termination sound is generated by the speaker 209. is output.

(F) Measurement end point 405
When the measurement period 404 ends and the measurement end point 405 comes, the speaker 209 outputs a normal end sound. The radio wave measurement device 130 determines whether the radio wave measurement value graph 410 is good or bad at an appropriate timing after the measurement end point 405 . In determining whether the radio wave measurement value graph 410 is good or bad, for example, the radio wave measurement device 130 determines whether or not the value of the radio wave measurement value graph 410 has fallen below the threshold value 411 a predetermined number of times during the measurement period 404 . If the radio wave measurement device 130 determines that the value of the radio wave measurement value graph 410 has fallen below the threshold value 411 a predetermined number of times, the radio wave measurement device 130 stores “fail” as the measurement result in the radio wave measurement result 206, and the radio wave measurement value graph 410 is not less than the threshold value 411 for a predetermined number of times, the measurement result "good" is stored in the radio wave measurement result 206. FIG.

(G) End of Passenger Conveyor Operation 406
When the operator stops the passenger conveyor 110, the value of the passenger conveyor speed graph 440 decreases and the periodic change of the magnetic sensor value graph 430 disappears. As the speed of the step 120 decreases, the period of the waveform of the magnetic sensor value graph 430 becomes longer, and when the step 120 stops, the period of the waveform of the magnetic sensor value graph 430 becomes constant.

(H) Cover plate opening work period 407
By opening the cover plate 160, the values of the radio wave measurement value graph 410 and the illuminance sensor value graph 420 increase. In this example, since the cover plate 160 is opened while being shifted, the values of the radio wave measurement value graph 410 and the illuminance sensor value graph 420 increase according to the opening ratio.

Also, since the cover plate 160 is configured to contain a magnetic material such as iron, the amount of magnetism decreases according to the rate at which the cover plate 160 is opened, and the value of the magnetic sensor value graph 430 also decreases.

In this embodiment, since it is determined that the conditions for measuring radio waves are satisfied and the radio waves are measured, it is possible to accurately diagnose whether or not the machine room of the passenger conveyor is in an environment where wireless communication is possible. can.

The embodiments described above have, for example, the following characteristic configurations.

A radio wave measurement system (e.g., radio wave measurement system) for measuring radio waves received by a radio communication device (e.g., radio communication device 140) provided in a machine room (e.g., machine room 150) of a passenger conveyor (e.g., passenger conveyor 110) 100), wherein a first sensor (e.g., illuminance sensor 131, magnetic sensor 132, image sensor, millimeter wave radar); a second sensor (for example, magnetic sensor 132, image sensor, millimeter wave radar) provided in the machine room for detecting the operating state of the passenger conveyor; A measurement processing unit ( For example, a measurement processing unit 208) is provided, and when the measurement processing unit determines that the opening/closing member is closed and determines that the passenger conveyor is operating, conditions for measuring radio waves are set. It is determined that the condition is satisfied (for example, see steps S308 and S309).

In the above configuration, for example, it is determined that the conditions for measuring radio waves are satisfied, so it is possible to avoid a situation in which radio waves are measured under erroneous conditions. In addition, for example, since the system uniformly determines whether the conditions for radio wave measurement are satisfied, differences in the environment in which radio waves are measured by workers can lead to poor communication during operation, requiring investigation of the cause. It is possible to reduce the number of cases where

The first sensor is an illuminance sensor. (for example, the illuminance sensor 131), and when the measurement processing unit starts measuring radio waves for diagnosing whether wireless communication by a wireless communication device provided in the machine room is possible, It is determined whether or not the sensor value of the first sensor exceeds the threshold value (for example, see step S308), and the output unit determines whether the sensor value of the first sensor exceeds the threshold value by the measurement processing unit. If so, it outputs that the radio wave measurement for the above diagnosis has failed (see step S315).

It is possible to shorten the time to obtain the results under the conditions. In addition, since the failure of the radio wave measurement is output because the opening/closing member is not closed, for example, the operator can grasp the cause of the failure and easily take measures to measure the radio wave under the correct conditions. will be able to go to
