Abstract
The utility model discloses a tension sensor used for a steel cable monitoring alarm, which is characterized by comprising a loop wire. An inner core of a double-core multi-strand outdoor lead is removed and welded with two copper wires, thus forming the loop wire; the top end of the loop wire is connected with an I/O interface of a singlechip; and the loop wire can bear a tension lead of 4 kilograms. The tension sensor used for the steel cable monitoring alarm has the advantages that the tension sensor is fixed on a steel cable, the lead loop is closed and in a '0' signal state in a normal condition, the tension sensor is coupled by an optical coupler and added with a fixed '1' signal of the singlechip in a reverse-phase way, and the singlechip is in a dormant state. The steel cable is cut, a tensile force or self-gravity of the steel cable can break the tension sensor, after the loop is broken, the signal is transmitted to a '0' signal of the I/O interface of the singlechip through the optical coupler, and the singlechip starts the alarming program immediately and gives an alarm to an alarm receiver. The tension sensor is simple and easy to use, has reliable and safe performance, extremely convenient operation and use, low cost and remarkable social benefit, can effectively monitor the steel cable, and can give an alarm immediately after the steel cable is cut off.
Description
Technical field
The utility model relates to a kind of wirerope monitoring alarm pulling force sensor, belong to the monitoring alarm technical field.
Background technology
The disconnected cable alarm of existing machine room cable can not in time be reported to the police during actual the use owing to its structural reason.This is to cut off wirerope earlier because steal burglar's employing of telecommunication cable, and telecommunication cable is landed, and removes the steel card of attached cable then, cuts off the means that cable is run away at last, thereby makes the disconnected cable alarm of existing machine room cable in time not report to the police.
Summary of the invention
The utility model proposes a kind of wirerope monitoring alarm pulling force sensor, its purpose is intended to effectively wirerope be implemented monitoring, as long as wirerope is just cut off and can in time send warning message.And it is simply and very practical that sensor is made every effort to.
Technical solution of the present utility model: its structure is made up of a loop wire, and this loop wire is welded by getting 2 copper cash of inner core in the outdoor lead of a twin-core multiply, and the top of loop wire and single-chip processor i/o mouth join, and this loop wire can bear 4Kg pulling force lead-in wire.
Advantage of the present utility model: pulling force sensor is fixed on the wirerope, and the lead-in wire circuit closed is " 0 " signal under the normal condition, and through photo-coupler coupling and anti-phase fixing " 1 " signal of single-chip microcomputer that is added to, single-chip microcomputer is in dormant state.As long as wirerope is cut off, the pulling force of wirerope or self gravitation just can be broken the pulling force sensor lead-in wire, and the signal after the loop is destroyed is sent into single-chip processor i/o mouth " 0 " signal through photo-coupler, and single-chip microcomputer starts alert program immediately, gives the alarm to the personnel of receiving a crime report.Be simple and easy to usefulness, dependable performance safety, it is extremely convenient to manipulate, and cost is low, obvious social benefit.Can implement monitoring to wirerope effectively, as long as wirerope is just cut off and can in time send warning message.
Description of drawings
Accompanying drawing 1 is the utility model user mode synoptic diagram.
Among the figure 1 is pull switch unit, the 2nd, Signal Spacing unit, the 3rd, wirerope or cable, the 4th, single-chip microcomputer, the 5th, pulling force sensor.
Embodiment
Pulling force sensor, its structure is made up of a loop wire, and this loop wire is welded by getting 2 copper cash of inner core in the outdoor lead of a twin-core multiply, and loop wire can bear 4Kg pulling force lead-in wire.The top of loop wire is fixedly on wirerope or the cable, the terminal I/O mouth that is connected to single-chip microcomputer by pulling force sensor through the Signal Spacing unit.
Contrast accompanying drawing 1, pulling force sensor is equivalent to pull switch unit 1, is formed by the cable transformation of the way, bears pulling force and is not more than 4Kg, is installed on monitored wirerope or the cable 3, just often is in closure state; When wirerope or cable 3 are pulled, pulling force is during greater than 4Kg, and pulling force sensor 5 contacts disconnect.Signal Spacing unit 2 main devices are photoelectrical couplers, and effect is the direct connection of isolating between pulling force sensor 5 and the single-chip microcomputer 4, avoid interference signal and import single-chip microcomputer into and cause misoperation.Pull switch is closed or when opening, and the optically-coupled of signal in Signal Spacing unit 2 amplified and sent into single-chip microcomputer 4 after anti-phase.
Described pulling force sensor is to get 2 copper cash of inner core to be welded to form a loop wire in duplex wire, and its pulling force that can bear is greatly about about 4Kg.For telecommunication cable hang usefulness wirerope its set up that to require be that pulling force with 2000Kg is unsettled with it, although fixedly wirerope of clamping plate is all arranged on every wire bar, but the power of strap is much smaller than 2000Kg, the pulling force of the 4Kg that the own wt that adds wirerope through the power of clamping plate decay necessarily bears greater than sensor, so, will move and send disconnected cable signal to single-chip microcomputer apart from the pulling force sensor of breakpoint 100M as long as wirerope cut off.
Pulling force sensor is fixed on the wirerope, and the lead-in wire circuit closed is " 0 " signal under the normal condition, and through photo-coupler coupling and anti-phase fixing " 1 " signal of single-chip microcomputer that is added to, single-chip microcomputer is in dormant state.As long as wirerope is cut off, the pulling force of wirerope or self gravitation make pulling force sensor move and send into the single-chip processor i/o mouth by photo-coupler and send " 0 " signal that single-chip microcomputer starts alert program immediately, gives the alarm to the personnel of receiving a crime report greater than 4Kg.
Claims (1)
1. wirerope monitoring alarm pulling force sensor is characterized in that being made up of a loop wire, and this loop wire is welded by getting 2 copper cash of inner core in the outdoor lead of a twin-core multiply, and the top of loop wire and single-chip processor i/o mouth join, and this loop wire can bear 4Kg pulling force lead-in wire.
