Description

DEVICE AND METHOD FOR ALARMING DANGER OF THE TEMPORARY STRUCTURE}

The present invention relates to an alarm device, in particular, by detecting the displacement state of the load and inclination by using the unit sensor in the main danger area of the temporary facility, and when the predetermined management value is reached, the load state by the change of the warning color and the alarm sound in stages The present invention relates to a hazard warning device and method for a temporary construction structure that enables the user to immediately indicate and respond to the safety status of the temporary installation in the field.

Currently, in the temporary equipment for foundation excavation such as construction and civil engineering, the stability and stability of the temporary facility are judged by reviewing the displacement and load measurement data of the temporary facility through periodic site measurements in the office and then feeding back to the site.

However, this method takes a long time to determine the measurement results, and it is not possible to have an immediate on-site response system due to the delay of the judgment and evaluation of the measurement experts, so that it is impossible for anyone to observe the safety status of the temporary facility at all times.

Existing equipment's danger alarm system is to install various sensors such as earth pressure gauge, inclinometer, load gauge and strain gauge in the main members of the temporary facility such as strips or vertical materials of the temporary facility. There is a conventional alarm system using simple mechanical and electrical devices.

These alarm devices are for the wide area ground, which may cause an increase in the number of installation points and waste of manpower and time due to the measurement of unnecessary areas.Although the alarm device is crude, it is inconvenient to manufacture and install, and even if the initial value for measurement is set, Due to the characteristics of the main earth pressure, groundwater level, soil type, etc., the main earth pressure changes continuously, so it is difficult to judge whether the state of the main member is in a dangerous state, and it is difficult to recover in case of damage caused by external impact, and difficult to maintain. There are limitations to the field application.

In addition, the existing sensor management method does not perform integrated functions because the functions of data storage, comparative analysis, transmission, and danger indication (speakers, etc.) are separated from each other. Although the data is sent to the measurement management office, it is configured to send the result to a specific person and take action when the management threshold is exceeded, but this implies that there is a lack of immediate response in case of an emergency.

In addition, conventionally, it is difficult to always check the progress of the displacement of the temporary facility with the naked eye, so it is not possible to immediately respond to the risk factors occurring in the field, such as waiting until the measurement result is determined to determine whether the safety state is correct. It is difficult to adjust the measurement frequency of the city, establish reinforcement measures for temporary facilities, and secure spare time for safe evacuation of workers.

The technical problem of the present invention is proposed to solve the above problems, and detects the displacement state of load and inclination by using a unit sensor (load cell, inclinometer, etc.) at a major danger part of a temporary facility, When reaching, the load status can be displayed by changing the light color of LED light, alarm sound, digital display, etc., so that it is possible to promptly predict and cope with the safety status of the temporary facility at the site. It is possible to always observe the displacement status, adjust the measurement frequency at the time of danger notice, establish reinforcement measures for temporary facilities, and secure extra time for safe evacuation of workers, thereby preventing safety accidents.

It includes the function to input the management criteria for each stage according to the site situation and conditions such as the setting function.

4 shows an example of the external appearance of the danger warning device of the temporary structure according to the embodiment of the present invention having such a configuration.

Referring to FIG. 4, a hazard warning device of a temporary structure according to an exemplary embodiment of the present invention may include a hazard indication including first, second, and third light emitting display devices 331, 332, and 333 displaying white, yellow, and red colors. The lamp 316, the data transmitter 312, the liquid crystal display 315, and the like are seen from the front.

Such an appearance may be variously modified as necessary, and the appearance of the load cell 322 and the inclinometer 311 may also vary as necessary.

Then, the operation of the danger warning device of the temporary structure according to the embodiment of the present invention having such a configuration will be described in detail.

5 is a flowchart illustrating an operation of the danger warning apparatus of the temporary structure according to the embodiment of the present invention.

Referring to FIG. 5, first, when power is applied by the power supply unit 317, the temperature sensor 319 measures the temperature and transmits the temperature to the control unit 313 (S510).

Then, the controller 313 reads the first and second reference values corresponding to the temperature from the memory 310 (S520), that is, the first and second reference values may be read originally, but the error according to the temperature is corrected. The first and second reference values corrected for reading are read.

Here, the correction value is stored in the memory 310 in the form of a table, but the controller 313 may calculate the correction value as necessary. The reference value is initially input by an administrator by operating the input unit 314, and the control unit 313 stores the same in the memory 310.

Then, the controller 313 receives the sensing value from the sensor unit 320 (S530), and compares the received sensing value with the first reference value (S540). At this time, the first reference value is an upper limit reference value, and is a value used as a standard for danger warning.

When the comparison result exceeds the first reference value, the controller 313 gives a warning of danger.

In particular, the controller 313 turns on the red light emitting diode 333 of the danger indicator 316, turns on the warning lamp 311, sounds the siren through the speaker 318, and senses a sensing value on the liquid crystal display 315. And the current danger warning situation.

This ensures that field personnel are evacuated and further action is taken quickly. In addition, the controller 313 transmits the data sensed through the data transmission apparatus 312 and the risk warning situation to the measurement management system 400 (S550).

On the other hand, if the sensing value is less than the first reference value, it is determined whether the sensing value is greater than or equal to the second reference value of the risk notice level less than the first reference value (S560).

If the sensing value is greater than or equal to the second reference value, the controller 313 foretells a danger. At this time, the yellow light emitting display device 332 is turned on (S570), and the warning lamp 311 is weaker or turned off than the danger notice situation. The speaker 318 weakly sounds or turns off the siren. In addition, the liquid crystal display 315 displays the sensing value and the present danger prediction situation.

And you can tell if it can be a dangerous situation if you need to.

On the other hand, if the sensing value is less than the second reference value, the controller 313 turns on the white light emitting diode 331 (S580), and displays the sensing value and current normal on the liquid crystal display 315.

Then, if necessary, the sensed data is transmitted to the measurement management system 400.

In the above process, the value sensed by the sensor unit and the basic principle of risk determination will be described in more detail as follows.

Ε = P / AE in the elastic region during tension of tensile members such as strands and steel rods, and the amount of elongation (ε) is proportional to the tension force (P) and is inversely proportional to the working area x elastic modulus (AE), so the displacement of the temporary facility (δ) In consideration of the tension force (P) of the tension member and the angle (θ) in which the tension member is installed, it can be seen that δ = P / AE × COSθ. Therefore, the amount of tension or displacement can be obtained indirectly with the unit sensor, so it is possible to measure the displacement of the temporary facility.

For example, the load delivered to the temporary facility varies depending on the depth of the trench, the type of soil, and the groundwater level.All of these loads are transmitted to the tension member, so the risk of the safety of the temporary facility due to the change in the load of the most vulnerable tension member in the temporary facility. It is possible to determine whether or not. In addition, if the load is transmitted to the compression member according to the type of provisional facility, the change of the load due to the compressive force behaves within the range that does not exceed the allowable compressive strength of the compression member, so that the judgment on the safety of the provisional facility is equally applied. This is possible.

In the embodiment of the present invention by installing a risk warning device that can immediately check the measurement results in the unit sensor (ex. Load cell, inclinometer) used during construction or maintenance measurement data to be measured in real time and set time In addition to the function of transmitting to the metrology management office, it implements the function of delivering the caution alarm so that it can be directly recognized by the manager or worker working around the site when the set management standard value is continuously compared and analyzed.

In this case, various sensors can be applied as necessary, and a warning can be given under complex conditions. For example, it can be a warning if one condition is satisfied or a warning when two or more conditions are satisfied.

Among these, the first and second reference values using the load cell may be applied as shown in the following table.

Figure 112008054363441-PAT00001

The scope of application of the control standard values in Table 1 above can be changed according to the design conditions and site conditions, and the operation functions and response measures can be changed.

Such a risk warning device according to an embodiment of the present invention can display the safety status for each step of the temporary facility. In other words, by installing the danger alarm device on the main members, the safety status of the temporary facility is always displayed in accordance with the step-by-step management standard value by comparing the amount of change or displacement caused by the load and stress in real time or at a set time to predict the safety of the temporary facility in the field in advance. It is possible to do

In addition, when the load cell installed in the main danger area is detected and the control value is reached from the management standard value, the safety status of the temporary facility is indicated by displaying the load status in various ways such as the warning light color of the LED lights, the change of the alarm sound, and the digital display. It is possible to predict the danger of accidents, and all managers and workers can visually observe the load and displacement status of temporary facilities immediately on site.

In addition, in the embodiment of the present invention, it is possible to store, compare, transmit and output data in real time or at a set time.

It is possible to save the trend of load change as a graph by setting the management standard value for each stage, saving and comparing the measured data in real time or set time, and transmitting it to wire / wireless to the measurement control room. It is easy to adjust the measurement frequency, establish reinforcement measures for temporary facilities, and secure spare time for safe evacuation of workers.

In addition, in the embodiment of the present invention it is possible to temperature correction according to the characteristics of each sensor. In other words, sensors such as load gauges and inclinometers are sensitive to temperature changes depending on site conditions, but measurement results are changed by temperature changes even when no external force is applied.

Therefore, a built-in temperature sensor in the danger alarm device includes a calculation function to correct an error due to temperature change according to the temperature constant for each sensor, thereby making it possible to calculate accurate measurement results. In addition, only the calibration of the unit sensor (load cell, inclinometer, etc.) can be used for other sites only, and it is easy to increase the convenience of installation and easy maintenance by allowing the magnetic attachment and detachment.

In addition, the embodiment of the present invention is easy to power supply and installation / disassembly. It is easy to install in difficult access area because it can be attached and detached to steel materials by being configured to apply various power sources such as power, battery, solar system, etc.

In addition, although not described in the embodiment of the present invention, it is possible to apply to the group member and the form form tie.

The present embodiment changes the concrete load and side pressure according to impact and work load, slump value, temperature, pouring height, and pouring speed during concrete pouring. Application is possible.

The embodiments of the present invention described above are not implemented only through the apparatus and the method, but may be implemented through a program for realizing a function corresponding to the configuration of the embodiment of the present invention or a recording medium on which the program is recorded. Implementation can be easily implemented by those skilled in the art from the description of the above-described embodiments.
