Description

  The present invention relates to a work site monitoring apparatus for monitoring a suspicious person or the like at a construction site such as a construction site.

  Construction sites such as construction sites contain materials for construction, civil engineering-related materials, and construction equipment. However, in recent years, materials are often stolen because they are unattended at night. doing. For this reason, monitoring devices have been proposed in which a monitoring camera or sensor is installed to notify when an abnormality is detected and a captured image is stored. For example, in Patent Document 1, a monitoring camera, a speaker, an indicator lamp, an infrared sensor, and a pole equipped with a control device that performs a predetermined alarm operation when an abnormality is detected are installed at the monitoring target site at appropriate intervals. Detection and notification were performed.

  On the other hand, since most of such construction sites are outdoors, countermeasures against heat stroke are necessary in the summer so that workers can work safely, and a device that monitors the work environment at outdoor construction sites For example, there has been a heatstroke prediction apparatus for predicting heatstroke described in Patent Document 2. Based on the information of the temperature / humidity sensor, an alarm signal is transmitted to the outside when both numerical values of temperature and humidity exceed a predetermined value set in accordance with the work environment.

FIG. 6 is a schematic configuration diagram of a monitoring system including a work site monitoring device and a communication destination thereof, and FIG. 7 is a functional block diagram of the monitoring control unit 5 incorporated in the housing 4. As shown in FIGS. 6 and 7, the monitoring control unit 5 includes a wireless communication unit 51 that wirelessly communicates with an external management server 15 via a mobile phone communication network and an Internet network that constitute the communication network N, a threshold value that issues an alarm, and the like. Memory 52 for storing various messages for reporting various setting values and alarm contents from speaker 6, first sensor (first IF) 53 for receiving signals output from human sensor 1 and temperature / humidity sensor 2, indicator lamp 3, a second interface (second IF) 54 to which the speaker 6 is connected, a monitoring control unit CPU 55 that controls the monitoring control unit 5, a power supply unit 56, and the like.
The sensors 1 and 2, the indicator lamp 3, and the speaker 6 are supplied with power from the monitoring controller 5 via the first IF 53 and the second IF 54.

The memory 52 stores, for example, probability information about the occurrence of heat stroke from temperature / humidity information in addition to a threshold value for issuing an alarm. When it reaches a certain value, a heat stroke danger signal is output, and a heat stroke alarm is issued from the indicator lamp 3 and the speaker 6.
The monitoring control unit CPU 55 communicates with the management server 15 every minute, for example, and transmits the values acquired from the sensors and the calculation results to the management server 15.

  The human sensor 1 is an infrared sensor, and includes three infrared sensors including two sensors that detect horizontal infrared rays and a sensor that detects infrared rays from the ground direction. With this configuration, intruders can be detected (sensed) by reducing malfunctions caused by bird and tree shaking, and a sensing signal is output to the monitoring controller 5 when a moving object such as a suspicious person is sensed.

  The temperature / humidity sensor 2 measures temperature / humidity, for example, every minute, and outputs measurement data to the monitoring controller 5.

The indicator lamp 3 has light emitting portions of three colors of red, blue, and yellow, and emits light under the control of the monitoring control unit 5. For example, when a suspicious person is detected, the red illumination is blinked. When a heat stroke alarm is issued, the yellow illumination is blinked. When the wind speed exceeds a predetermined value, the blue illumination is turned on.
The speaker 6 is installed at the bottom of the housing 4 and emits various alarm sounds and various messages under the control of the monitoring control unit 5.

Specifically, when the human sensor 1 detects the presence of a suspicious person, an alarm operation is performed. For example, the indicator light 3 blinks a red light, etc., a threatening sound is issued from the speaker 6, and, for example, “There is a suspicious person, please leave immediately” is reported.
Further, if the temperature and humidity satisfy a certain condition from the information of the temperature and humidity sensor 2, a heat stroke alarm is issued. For example, the indicator lamp 3 turns on a blue light, and a message such as “Please be careful about heat stroke” is sounded together with the sound of an alarm sound from the speaker 6.
The suspicious person's detection and the monitoring status of the heat stroke alarm are transmitted from the wireless communication unit 51 to the management server 15 via the communication network N, and the user terminal such as a portable terminal managed by the administrator from the management server 15. 16 is transmitted.

  In this way, the work site monitoring device can be easily attached regardless of whether the attachment object is a single pipe pipe 10 or a pillar such as a concrete pillar 9 or a pole, and the attachment object is not selected when moving. In addition, since the human sensor 1, the temperature / humidity sensor 2, the speaker 6, and the mounting bracket 11 are assembled in the housing 4 in which the monitoring control unit 5 is housed, the work site monitoring device can be attached to a pole or the like by a single mounting operation. It can be fixed to the mounting target and can be mounted with simple work.

In the above embodiment, the human sensor 1 and the temperature / humidity sensor 2 are provided. However, only the human sensor 1 may be provided, or a monitoring camera that operates in conjunction with the human sensor 1 is provided. Also good.
In addition to the human sensor 1 and the temperature / humidity sensor 2, a wind speed sensor may be assembled, and in addition to monitoring a suspicious person, it is preferable to monitor a work environment, particularly a high place work environment.
