Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific embodiments:
the utility model discloses a construction safety is with human response and risk detecting system mainly uses on the construction site, and this system sets up the mode for the distributing type, can ensure the safety of people and equipment, can guarantee construction site's construction order.
The utility model discloses mainly include by human induction system and risk monitoring devices according to the functional partitioning. As shown in fig. 2, the human body sensing device 1 mainly includes a thermal sensor 11 and a position sensor 12. The heat-sensitive sensor 11 is used for sensing a heat signal with the temperature close to the temperature of a human body, the heat-sensitive sensor 11 can distinguish the human body from materials, and the interference of moving objects such as the materials and other heat sources on the safety protection of personnel can be prevented. The position sensor 12 can set a detection distance according to a construction site danger range, and can monitor the position condition of a human body in real time when a person enters the detection distance. As shown in fig. 3, the risk monitoring device 2 mainly includes a current sensor 21, a pressure sensor 22, a circuit breaker 23, and an alarm 24. The current sensor 21 is used for monitoring and ascertaining the working state of the equipment, and the current sensors are respectively arranged on the main operation part of the equipment and the circuit of the main control system. The pressure sensor 22 is used for monitoring and ascertaining the loading condition of the equipment and is arranged at a main stress structure of the equipment. The circuit breaker 23 is used for terminating the action of the equipment before danger occurs, and is arranged on a main control circuit and a brake circuit of the equipment. The alarm 24 is used for sending warning information to security threatened personnel and has a reminding function and an alarming function. The system also has a chip that processes information and issues control signals.
In actual use, the human body sensing device 1 and the risk monitoring device 2 are installed on each mechanical device in a construction site, and the sensing range of the position sensor 12 is set to a value capable of covering the device influence range, for example, the sensing range can be set to 8-13 m. The current sensor 21 is attached to the lines of the main operation part and the main control part of the equipment, the pressure sensor 22 is installed at the main stress structure of the equipment, and the circuit breaker 23 is installed on the main control line and the brake line of the equipment.
As shown in fig. 1, the system works as follows: when the equipment is operated, if a person enters an affected area, the heat-sensitive sensor 11 and the position sensor 12 are triggered simultaneously, and at the moment, the system can judge whether the equipment is in a working state or not by reading the values of the current sensor 21 and the pressure sensor 22. At this time, when the device is not in operation or the current sensor 2 and the pressure sensor 22 are in normal range, the alarm 24 will send out a warning to warn the personnel to pay attention to safety. When the equipment is in a working state and any one of the current sensor 2 and the pressure sensor 22 is monitored to be in an abnormal range, the alarm 24 gives an alarm, and the breaker 23 breaks a working loop of the equipment according to the type of the equipment and starts corresponding braking measures, so that the accident that the machine damages personnel is avoided.
