Technical Field
The utility model belongs to the field of safety ropes, and particularly relates to an on-site alarm system for limited space operation.
Background
The existing limited space intelligent alarm system comprises: the gas detector is worn on an operator, the alarm is carried by a guardian, the gas detector is in wireless connection with the alarm through a wireless transmitter and a wireless receiver, and the gas detector is used for sending an alarm signal to the alarm when the content of toxic gas in a working space exceeds the standard; the safety belt is worn on the body of the operator, one end of the safety rope is connected with the safety belt, and the other end of the safety rope is carried by a guardian; also comprises protective clothing worn on the guardian. The defects are that: the signal transmission in the limited space is poor, and the signal is inconvenient to transfer in time. It is therefore desirable to design an in-situ alarm system for safety prompts to operators in confined spaces, including operators in confined spaces and operators outside of confined spaces.
Disclosure of Invention
In view of the technical problems in the background art, the on-site alarm system for limited space operation provided by the utility model is free from signal interference, and can give an alarm in time to a guardian if an operator in a limited space cannot use intercom equipment and alarm equipment due to poisoning, so that the guardian can take rescue measures in time.
In order to solve the technical problems, the utility model adopts the following technical scheme:
an in-situ alarm system for limited space operation comprises a human body induction sensor which is respectively connected with an out-of-limited-space alarm device, an out-of-limited-space alarm controller and an in-limited-space alarm device in series, wherein the human body induction sensor, the out-of-limited-space alarm device, the out-of-limited-space alarm controller and the in-limited-space alarm device are powered by a battery.
In a preferred scheme, the alarm device outside the limited space comprises a first alarm indicator lamp and a first buzzer; the first alarm indicator lamp is connected with the first buzzer in series.
In the preferred scheme, the alarm device in the limited space comprises a manual alarm starting button and a report eliminating button which are connected in series.
In the preferred scheme, the alarm device in the limited space comprises a second buzzer and a second alarm indicator lamp, and the second buzzer is connected with the second alarm indicator lamp in series.
The utility model has the following beneficial effects:
the system is used for being arranged on a safety rope, when the operation in a limited space is carried out, if an operator in the limited space cannot use intercom equipment and alarm equipment due to poisoning, a human body induction sensor detects that a human body is not active, and when the human body activity is still not detected within a set time threshold (for example, the time threshold is 10 seconds), the system gives an alarm to a guardian, prompts the guardian, and the guardian can take rescue measures in time and cannot be interfered by signals. When the guardian in the limited space finds that the abnormality occurs outside the limited space, the alarm button can be started to give an alarm to operators in the limited space. The monitoring efficiency is improved, and the operation information of personnel in and out of the limited space can be prompted, so that bidirectional prompt is realized.
Drawings
The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:
fig. 1 is a circuit diagram of the present utility model.
In the figure: the human body induction sensor 1, the alarm device 2 outside the limited space, the first alarm indicator lamp 3, the first buzzer 4, the alarm controller 5 outside the limited space, the manual alarm starting button 6, the alarm eliminating button 7, the alarm device 8 in the limited space, the second buzzer 9 and the second alarm indicator lamp 10.
Detailed Description
Example 1:
the preferred scheme is shown in fig. 1, an on-site alarm system for limited space operation comprises a human body induction sensor 1, wherein the human body induction sensor 1 is respectively connected with an external limited space alarm device 2, an external limited space alarm controller 5 and an internal limited space alarm device 8 in series, and the human body induction sensor 1, the external limited space alarm device 2, the external limited space alarm controller 5 and the internal limited space alarm device 8 are powered by a battery 11. The utility model changes the traditional wireless alarm equipment into the on-site alarm equipment, when the limited space operation is carried out, the operator cannot use the intercom equipment and the alarm equipment due to poisoning, the human body induction sensor detects that the human body is not active, and when the human body activity is still not detected within the set time threshold (for example, the time threshold is 10 s), the system gives an alarm and prompts the guardian. When the guardian in the limited space finds that the abnormality occurs outside the limited space, the alarm button can be started to give an alarm to operators in the limited space. The monitoring efficiency is improved, and the operation information of personnel inside and outside the limited space can be prompted.
The branch circuit formed by the human body induction sensor 1 and the limited space outside alarm device 2 is connected in parallel with the branch circuit formed by the limited space outside alarm controller 5 and the limited space inside alarm device 8.
