Description

A kind of two-wire interacts tandem multi-site unified security early warning system

Technical field

The utility model belongs to electron and electrician technical field, it particularly relates to arrive a kind of two-wire interaction tandem multistation Point unified security early warning system.

Background technology

Construction safety, the safety of particularly hazardous area operation is (including chemical industry construction, mine construction, landslide surface operation, flash Slope road excavation, tunnel portal and face excavation, special river course flood discharge etc.) it is the higher industry of accident risk, government is to peace Full problem is extremely paid attention to, and has formulated the trouble free service policy of " put prevention first, safety first, the comprehensive regulation ".

At present China's hazardous area scope of operation typically arranges full-time security official, is responsible for safety production program, tissue, commander, association A series of activities adjusted or monitor, unsafe acts, the unsafe condition of installations and facilities, the operation of personnel in key monitoring construction Place and environmental unsafe factor and managerial dangerous defect.When there is any dangerous situation in hazardous area job site, Full-time Security Officer can in time notify the rapid rut of related personnel from job site, and rescue contral center personnel can start rapidly Emergency preplan, carries out corresponding urgent measure.But construct for many scope of operations simultaneously in the case of, such as multiple-arch tunnel of growing up is excavated During, because tunnel is generally located in mountain valley middle and lower part, each tunnel Inner Front End excavates face and hole outside is difficult foundation and has The communication mode of effect.At present hazardous area scope of operation Forewarning Measures take intercom to be linked up mostly.But the signal of intercom is passed Defeated distance and signal penetrate the limited in one's ability of barrier, it is difficult to adapt to many scope of operation random forecasts, the very first time while receiving danger Feelings alarm, the very first time, simultaneously rut was required from the early warning that, very first time starts rescue simultaneously.

Therefore, the problems referred to above urgent need to resolve of prior art.

Utility model content

The practical problem that the utility model runs into according to work and life, by the way of being mechanically connected, designs one kind Can realize that unlimited number of different places arbitrarily open and close the circuit switchgear of same group of electric equipment.With existing electricity Way switch device is compared, and this two-wire interacts serially connected single pole infinite and throws circuit switchgear without the need for high-end instrument controlling equipment, There are low cost, easy to operate, quick, energy-saving and environmental protection, also can slightly be transformed by existing interlock circuit switching device Form.

The utility model is claimed a kind of two-wire interaction tandem multi-site unified security early warning system, and its feature exists In the system includes a rescue contral center and N number of security monitoring website, and each security monitoring website is respectively provided with one Alarm contact and two sirens, including：Switch KG (1), KG (1) siren, switch KG (2), KG (2) siren, switch KG (3), KG (3) siren ... switch KG (i), KG (i) sirens ... switch KG (N), KG (N) siren (wherein i be from So count, the N of i=3,4,5 ..., similarly hereinafter)；

Wherein first switch KG (1) includes first base binding post 1 and second base binding post 2, lid binding post on first 1. with second on lid binding post 2.；Second switch KG (2) including the 3rd base binding post 3 and the 4th base binding post 4, on the 3rd Lid binding post 3. with the 4th on lid binding post 4.；I-th switch KG (i) includes 4i-7 base binding posts, 4i-6 base wiring Post, 4i-5 base binding posts, 4i-4 base binding posts, lid binding post, 4i-5 on lid binding post, 4i-6 on 4i-7 Lid binding post on upper lid binding post and 4i-4；

System also includes, electrical equipment, power supply and power line；And KG (i) sirens are separately mounted on switch KG (i) nearby two Two sirens on root connection power line.

Further, circuit connecting mode is as follows：One pole of power supply connects first switch KG (1) simultaneously by power line First base binding post 1 and second base connecting pole 2；On the first of first switch KG (1) lid binding post 1., lid wiring on second Post 2. respectively by two power lines and KG (i) sirens be connected to N switch the 4N-7 bases binding post 5 of KG (N), the 4N-5 base lines post 7；The 4N-6 bases binding post 6,4N-4 bases binding post 8 of N switches KG (N) passes through respectively power supply The 4N-11 bases binding post 5,4N-9 binding posts 7 that line switchs KG (N-1) with (N-1) is connected；

N is switched and KG (N) sirens are sequentially connected in the manner described above to second switch KG (2) and KG (2) siren；

Lid binding post is 1. on the 3rd of second switch, 2. lid binding post connects power supply 10 simultaneously by power line on the 4th Another pole.

Maximum advantage is in this early warning system, when any one working face in hazardous area occurs dangerous situation, can press in time The siren switch being arranged near the working face, always has a circuit for series connection energization shape in now all early warning systems State, all sirens for being concerned about the scope of operation in whole hazardous area can be started simultaneously in the very first time and sounded the alarm, each operation Surface construction personnel can simultaneously receive dangerous situation the very first time and notify, and withdraw scene in time, while rescue center personnel can be according to feelings Condition carries out in time field rescue.

This early warning system is realized at any time, arbitrarily opening and closing in an arbitrarily different position by way of being mechanically connected Same safe early warning pilot switch is closed, without the need for buying and installing high-end instrument and equipment, can be according to landform, landforms, day gas bar Part and need of work increased or decrease in time the power supply line length of different work face control point, are arbitrarily being concerned about at scope of operation position Arrangement safety monitoring device and siren, are adapted to the scene many scope of operations in any hazardous area are constructed simultaneously when and lay early warning system, There is production, installation cost is low, easy to operate, quick, energy-saving and environmental protection.
