Description

Technical Field

[0001] The utility model relates to the technical field of building construction early warning, in particular to an early warning device for a building construction site. Background Art

[0002] Whether it is off-site construction or interior decoration construction, the construction period will be long, from a few months to one or two years. During the construction period, dust, noise and other adverse factors that may affect people's physical and mental health may be generated. Therefore, an early warning device is needed to monitor the construction site. The early warning devices in the existing technology are either installed on the ground, which takes up a lot of idle time, or fixed on the wall. However, due to unreasonable structural design, monitoring and early warning often have false alarms or even no warnings. Moreover, if it is fixed on the vertical wall for a long time, the heating of the equipment will also cause problems in the monitoring system. For this reason, there is an urgent need for an early warning device that does not need to occupy additional ground space and can accurately monitor the construction site over a large range.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0025] like Figures 1 to 4 As shown, the utility model includes an upper shell 1 and a lower shell 2 connected as a whole, which are divided into two parts. A high-density sponge 10 is sandwiched between the upper shell 1 and the lower shell 2 to reduce the vibration of the device itself and prevent monitoring errors caused by vibration.

[0026] The upper shell 1 includes side panels 102 installed on both sides of the front plate 101, a rear plate A103 and a top cover 104. The various components can be connected by conventional countersunk bolts or screws. A hole is dug in the center of the front plate 101, and a rotatable camera 3 is installed in the hole. The camera 3 can rotate in all directions and provide up to 2K ultra-clear image quality; four turbo fans 4 are inlaid around the camera 3, which can dissipate heat for the device and prevent dust from sticking near the camera 3. A fan control box 401 is installed behind each turbo fan 4, and electronic components such as motors for controlling the rotation of the fan are installed in the box. A monitoring module 301 is installed behind the camera 3, and the fan control box 401 and the monitoring module 301 are both fixed on the front plate 101.

[0027] Each of the side panels 102 is provided with four square grooves, in which vibration sensors 5 are installed. The grooves of the side panels 102 are matched in size with the vibration sensors 5 and the upper surface of the vibration sensor 5 is flush with the outer shell of the device, so as to ensure that when the device is installed on a wall or a beam, the vibration sensor 5 can be in direct contact with the installation position; a through hole is provided at the bottom of the groove, and the connecting line of the vibration sensor 5 passes through the through hole to be connected with the internal battery pack 8 or the controller 7; the center of the rear panel A103 is provided with a similar groove and vibration sensor 5, which provides a basis for sensing vibration at multiple angles.

[0028] The rear panel A103 is also provided with a number of hanging holes 1031 and a charging interface 6. After the rear panel A103 is removed separately, the battery pack 8 can be charged without removing it. The hanging holes can ensure that the device can be hung on the installation wall. The controller 7, battery pack 8 and wireless radio frequency module 9 are fixed on the inner wall of the rear panel A103. The controller 7 can adopt a conventional 51 single-chip microcomputer as the core. The battery pack 8 has a conventional lithium battery built in. The wireless radio frequency module 9 can be connected to a host computer (computer) to provide information to the host computer, be controlled by the host computer, and provide early warning information to the host computer when an abnormality is detected. The position of the charging interface 6 corresponds to the battery pack 8 and the two are connected.

[0029] The lower shell 2 is in the shape of an inverted right-angled trapezoidal prism, and a connecting hole 202 is provided at the same position on the top surface of the lower shell 2 as the high-density sponge 10, providing a connecting channel for the connecting wires of the upper and lower parts; the front surface of the lower shell 2 is a slope with an inclination angle of 35 degrees, and the back of the lower shell is closed with a rear plate B201 to facilitate the disassembly and assembly of the built-in module; the slope can provide a wider monitoring space for the built-in monitoring module; the lower shell 2 is equipped with a dust monitoring module 11 and a noise sensor module 12.

[0030] The dust monitoring module 11 is located above the noise sensor module 12 and both are fixed on the front inner wall of the lower shell 2; an air inlet 1101 and a sensor probe 1201 are provided on the front surface of the lower shell 2, and the air inlet 1101 is connected to the dust monitoring module 11 at the rear to monitor the air quality caused by dust on the construction site. The sensor probe 1201 is connected to the noise sensor module 12 at the rear, and the noise detection range can reach 30dB to 120dB.

[0031] Exhaust ducts 1102 are installed at the exhaust ports on both sides of the dust monitoring module 11, and the exhaust ducts 1102 are connected to the inner wall of the lower shell 2. An exhaust filter 1103 is arranged on the side of the lower shell 2, and the end of the exhaust duct 1102 corresponds to the exhaust filter 1103 to prevent large-volume impurities from entering the exhaust hole of the dust monitoring module and causing blockage.

[0032] The battery pack 8 of the utility model has the functions of all electrical components, and the controller 7 is connected to and controls all the electrical components.

[0033] The working principle of the utility model is as follows: (1) After the controller 7 and related sensors in the device are set with monitoring and warning parameters, the device is installed on a wall or beam without occupying ground space. (2) The camera 3 of the device is controlled by the program in the controller 7 to shoot in a fixed position. The vibration sensor 5 is in direct contact with the installation position, and the solid vibration conduction mode similar to bone conduction can accurately monitor the vibration of the construction site. The dust monitoring module 11 and the noise sensor 12 are also monitored in real time. For example, the vibration generated by the dust monitoring module 11 when inhaling air will be mostly absorbed by the high-density sponge 10, reducing the vibration error. (3) The controller 7 of the device is set to "sleep mode", that is, standby mode during non-working hours, and all components stop working. (4) When one of the noise, dust and vibration of the construction site reaches the set warning value, for example, the noise exceeds 95dB, the wireless radio frequency module 9 in the device transmits the warning information to the host computer, and the camera 3 rotates to shoot and record, and records in all directions. At this time, the user of the host computer can summarize the work records of the day, so as to carry out the next step of optimization.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
