At present, related personnel solve the problem that operators enter randomly by carrying out 'hanging and locking' in a limited space, but dangerous and harmful factors in the limited space are still not eradicated.
Aiming at the problems, the utility model provides a safety precaution system which is used for standardizing the operation flow of constructors and reducing harmful factors in a limited space so as to reduce the occurrence probability of accidents. Fig. 1 shows a first schematic diagram of a security system provided in an embodiment of the present utility model. As shown in fig. 1, the security system 100 includes: a space structure 101, an alarm device 102, a ventilation device 103, and a controller 104; the space structure 101 has a limited space in which articles can be accommodated, and has a guard door 1011, a guard door state detection device 1012 provided on the guard door 1011, and a ventilation device 103 provided on the space structure 101, the ventilation device 103 being in communication with the limited space and the environment outside the space structure 101, respectively, and the guard door state detection device 1012, the ventilation device 103, and the alarm device 102 being in communication with the controller 104.
In practical application, the limited space provided by the utility model is a closed or partially closed space.

When the guard door state detection device 1012 detects that the guard door 1011 is in an open state, the guard door state detection device 1012 and the ventilation device 103 are in communication connection with the controller 104, and after the controller 104 acquires a signal that the guard door 1011 is in an open state, the ventilation device 103 can be controlled to ventilate a limited space, and air in the limited space is replaced with air outside the space structure 101, so that the probability of exceeding the concentration of harmful gas in the limited space is reduced, and harmful factors in the limited space are reduced. Meanwhile, the alarm device 102 is also in communication connection with the controller 104, so that after the controller 104 obtains a signal that the guard door 1011 is in an open state, the alarm device 102 can be controlled to carry out safety reminding, the operation flow of constructors is standardized, constructors are reminded to be ready for protection, and the occurrence probability of accidents is reduced. On the basis, the safety precaution system 100 provided by the utility model can standardize the operation flow of constructors by ventilating and reminding the limited space, and reduce harmful factors in the limited space, thereby reducing the occurrence probability of accidents.
For example, for better standardizing the operator operation process, a camera may be provided on the alarm device or on the protective door, which camera may be connected in communication with the controller. When the protective door state detection device detects that the protective door is in an open state, after the controller obtains a signal that the protective door is in the open state, the controller can control the alarm device to carry out safety reminding, meanwhile, the controller is also used for controlling the shooting device to shoot protective equipment worn by constructors, and when the controller obtains the image from the shooting device, whether equipment worn by constructors accords with safety operation requirements can be judged. If the protective equipment worn by the constructor is judged to meet the safety operation requirement, the alarm device is controlled to stop safety reminding, and if the protective equipment worn by the constructor is judged not to meet the safety operation requirement, the alarm device is controlled to continue safety reminding.
The protection door state detection device provided by the embodiment of the utility model comprises a position detection device and/or an image detection device, wherein the position detection device and/or the image detection device are/is connected with the controller.
The alarm device comprises a voice alarm device which is arranged on the protective door and is in communication connection with the controller.
If the position detection device is selected as the protection door state detection device, if the current position of the protection door detected by the position detection device is different from the initial position of the protection door, after the controller acquires the signal, the controller controls the alarm device to carry out safety reminding and controls the ventilation device to ventilate the limited space, and air in the limited space is replaced with air outside the space structure.
If the image detection device is selected as the protection door state detection device, if the image detection device detects that the image of the protection door is different from the initial image of the protection door, after the controller acquires the signal, the controller controls the alarm device to carry out safety reminding and controls the ventilation device to ventilate the limited space, and the air in the limited space is replaced with the air outside the space structure.
Fig. 2 shows a second schematic diagram of the security system provided in an embodiment of the present utility model. As shown in fig. 2, the safety protection system 100 provided by the present utility model further includes a plurality of harmful gas sensors 105, where the probe of each harmful gas sensor 105 is located in a limited space, and the harmful gas sensor 105 is communicatively connected to the controller 104.
Illustratively, the probe of the harmful gas sensor 105 is used for detecting the concentration of harmful gas in the space, and the controller 104 is used for acquiring the concentration of harmful gas and judging the safety degree of the limited space based on the concentration of harmful gas; if the safety of the limited space does not meet the construction requirement, the controller 104 is further configured to control the ventilation device 103 to ventilate and the alarm device 102 to alarm. Specifically, the judgment standard of the safety degree of the limited space is as follows: the concentration of the harmful gas in the limited space is lower than a preset concentration value. The concentration of the harmful gas in the limited space is lower than a preset concentration value, and the controller 104 is used for acquiring the concentration of the harmful gas and judging the safety degree in the limited space to be safe; the concentration of the harmful gas in the limited space is higher than a preset concentration value, and the controller 104 is configured to obtain the concentration of the harmful gas, and determine that the safety degree of the space is dangerous.
The number of the harmful gas sensors provided by the embodiment of the utility model is not less than 3, and the distance between each harmful gas sensor is 0.9 times to 1.5 times of the height of the limited space. By limiting the number and the distance between the harmful gas sensors, the accuracy of the detected concentration of the harmful gas can be ensured, and the sensitivity of the safety protection system for detecting the harmful gas can be improved.
The alarm device provided by the embodiment of the utility model further comprises a photoelectric alarm device which is arranged on the space structure body and is in communication connection with the controller. When the concentration of harmful gas in the limited space detected by the probe of the harmful gas sensor is higher than a preset concentration value and the controller judges that the safety degree of the limited space is dangerous, the photoelectric alarm device is controlled to emit red light, the voice alarm device is controlled to carry out voice alarm, constructors are prompted to evacuate, and constructors are prevented from approaching to places where the concentration of the harmful gas exceeds the standard.
In an alternative manner, as shown in fig. 2, the security system 100 provided by the present utility model further includes a display device 106, where the display device 106 is communicatively coupled to the controller 104. If the safety level of the space does not meet the construction standard, the controller 104 can also control the display device 106 to display alarm information, the operating state of the harmful gas sensor 105, and the concentration of the harmful gas.
For example: when the concentration of the harmful gas in the limited space detected by the probe of the harmful gas sensor 105 is higher than the preset concentration value, the controller 104 in communication with the harmful gas sensor 105 can control the alarm device 102 to alarm, meanwhile, the alarm device 102 can transmit the parameter signals to the controller 104 and transmit the parameter signals to the display device 106 through the controller 104, and the parameter signals can include the total number of alarms in the alarm device 102, which probe of the harmful gas sensor 105 detects the harmful gas concentration exceeding the standard and the harmful gas concentration in the limited space.
It is understood that the controller provided by the utility model is a central controller controlled by a PLC, so that the automation of the flow can be realized without excessive manual intervention.
The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
