Abstract
A method for preventing mistaken entrance into a charged interval in an electric power engineering operation can timely remind and stop an operator mistakenly entering a barrier and prevent the mistaken entrance into the charged interval (a charged tower) to result in personal accidents. The method comprises the steps that a detector is temporarily arranged in a space required to monitor human body entrance in a prohibition barrier according to a field situation; an alarm is carried by a working principal or left in a master control room; the detector is started; once someone enters the space monitoring the human body entrance, the detector induces to confirm that a human body enters; after the detector confirms that someone enters, a wireless signal transmitter is automatically triggered to transmit a wireless alarm signal; the alarm automatically triggers acousto-optic alarm and prompts the number of the detector giving the alarm; and the working principal or a person in the master control room obtains the number of the detector giving the alarm after finding the alarm given by the alarm, immediately goes to a position where a person mistakenly enters the prohibition barrier according to the number of the detector giving the alarm, and orders the mistakenly entering person to leave the prohibition barrier.
Description
Technical field
The present invention relates to the method for preventing mistakenly entering charged chamber in a kind of power engineering operation.
Background technology
In power engineering, have circuit homework and power transformation operation, work responsible official is organizer and governor and the safety director of site operation.All the time on-the-spot in major tasks, operating crew's operation behaviour is conscientiously guarded to the behavior that jeopardizes the person, electrical network, device security that correction in time may occur.But for the upper work of the electrical equipment in complicated layout (complicated circuit location), maybe may have intersection, intermittently on charging equipment, work, in the maintenance of electric connecting member, when testing multi-specialized, many personnel and working, during shaft tower that particularly adjacent alive circuit is very near, the distant fallibility of constructing is stepped on, work responsible official can not control all sound of blocking that do not enter.Once there is mistakenly entering charged chamber (charged shaft tower), will there is personal injury.
Summary of the invention
The present invention will solve the problems referred to above that prior art exists, and providing a kind of can be strayed into while blocking and in time remind and stop operating personnel, prevents the method for preventing mistakenly entering charged chamber in the power engineering operation of mistakenly entering charged chamber (charged shaft tower) generation personal injury.
The method of preventing mistakenly entering charged chamber in the power engineering operation the present invention relates to, step is as follows:
1, according to field condition, in correspondence, do not enter to block and need to monitor the space that human body enters installation detector is set temporarily, warning horn is carried or stay master-control room by the responsible official that works;
2, start detector, once there be people to enter the space that monitoring human body enters, detector confirms have human body to enter being less than 2 seconds internal inductions; After detector confirms to have people to enter, automatically trigger wireless signal transmitter transmitting wireless alarm signal, continue wireless signal emission after 3 seconds stop signal transmitting time delay restart human body 10 seconds and enter detection;
3, warning horn, after receiving wireless alarm signal, triggers sound and light alarm automatically, the detector numbering that prompting gives the alarm; At warning horn, trigger after sound and light alarm, alarm condition is locked, and before inartificial contact is reported to the police, sound and light alarm does not stop;
4, work responsible official or master-control room personnel find to obtain the detector numbering of sending warning after warning horn warning, press and on warning horn, remove alarm button, remove current alarm condition, alarm returns to original state, and according to the detector numbering of sending warning immediately the personnel of rushing for be strayed into not enter and block position, order is strayed into personnel and leaves not enter and block.
Described detector is two and realizes omnidirectional detection.
The detected monitoring range of described detector is that 0-7 rice, angle are within the scope of 120 °.
Described detector is installed on the top of space that monitoring human body enters.
Described warning horn consists of wireless signal receiver, single-chip microcomputer, display screen and audible-visual annunciator, wireless signal receiver is after receiving wireless alarm signal, by single-chip microcomputer according to address code, the corresponding detector numbering of alerting signal the detector numbering that prompting is reported to the police on display screen are sent in judgement, then drive audible-visual annunciator work.
The invention has the beneficial effects as follows: can be strayed into while blocking and remind and stop in time operating personnel, prevent that mistakenly entering charged chamber (charged shaft tower) from personal injury occurring, be quick on the draw, measure be effective, is convenient to centralized management.
Accompanying drawing explanation
Fig. 1 is circuit block diagram of the present invention;
Fig. 2 is detector scheme of installation.
Embodiment
As shown in the figure, the method for preventing mistakenly entering charged chamber in this power engineering operation, step is as follows:
1, according to field condition, in correspondence, do not enter to block and need to monitor the space that human body enters installation detector is set temporarily, described detector is two and is installed on the top of space that detects monitoring, to realize omnidirectional detection, the detected monitoring range of each detector is that 0-7 rice, angle are within the scope of 120 °; Warning horn is carried or stays master-control room by the responsible official that works;
2, start detector, once have that people enters that monitoring human body enters space, detector confirms have human body to enter being less than 2 seconds internal inductions; After detector confirms to have people to enter, automatically trigger wireless signal transmitter transmitting wireless alarm signal, continue wireless signal emission after 3 seconds stop signal transmitting time delay restart human body 10 seconds and enter detection;
3, adopt the warning horn being formed by wireless signal receiver, single-chip microcomputer, display screen and audible-visual annunciator, wireless signal receiver is after receiving wireless alarm signal, by single-chip microcomputer according to address code, the corresponding detector numbering of alerting signal the detector numbering that prompting is reported to the police on display screen are sent in judgement, then drive audible-visual annunciator work, at warning horn, trigger after sound and light alarm, alarm condition is locked, and before inartificial contact is reported to the police, sound and light alarm does not stop;
4, work responsible official or master-control room personnel find to obtain the detector numbering of sending warning after warning horn warning, press and on warning horn, remove alarm button, remove current alarm condition, alarm returns to original state, and according to the detector numbering of sending warning immediately the personnel of rushing for be strayed into not enter and block position, order is strayed into personnel and leaves not enter and block.
The detector using in the present embodiment is infrared eye.
