Background technology
Contactor, is widely used in field of circuit control, and along with the research and development of each field automation equipment and universal, manual control switch's break-make has become as history.More and more automatically control, remote control switch becomes the key of smart machines.But the universal of contactor also brings certain problem, during Artificial Control contactor, by the experience of people, it can be determined that some unusual conditions of circuit, and in time by switch on and off.Popularizing of automation equipment, switch can not be reacted by the early stage abnormal state of fault in time in time, only when curtage exceedes predetermined value, directly disconnects switch, and now faulty circuit majority is to have resulted in irreversible loss.And the passive disconnection of switch, this equipment of certain in circuit can be caused infringement greatly, and then bring the loss that cannot estimate.
All circuit, before ging wrong, all have the fluctuation of curtage.Then its interior curtage has abnormality i.e. mutation status be monitored and report to the police, artificial or Based Intelligent Control can participate in timely, judge possible failure cause, thus take the initiative power-off or the timely operation intervening circuit, then can obtain the whip hand that circuit controls to a certain extent, it is to avoid loss.
Utility model content
Passive disconnection it is in the case of a fault for foregoing circuit switch, and the equipment in circuit is caused the technical problem of certain infringement, this utility model provides one and is arranged on contactor, curtage in the circuit accessed switch monitors in real time, when unusual fluctuations occurs in monitor value, the device being arranged on contactor carries out reporting to the police and circuit does the sudden change monitoring alarm device of pre-prompting of being out of order.
A kind of sudden change monitoring alarm device of auxiliary circuit switch, including sampler, comparator, single-chip microcomputer, alarm, it is characterized in that: described sampler accesses in the circuit at switch place, the curtage signal of Fixed Time Interval Acquisition Circuit, and two groups of adjacent monitoring signals are inputed to the two ends of comparator, the monitoring of adjacent monitoring signal is the sudden change value of measuring circuit curtage, so comparator is sudden change comparator, the result of sudden change comparator sends single-chip microcomputer to, and compare with the value preset in single-chip microcomputer, when fiducial value is beyond preset value, single-chip microcomputer sends the signal starting alarm device.
As important improvement of the present utility model, also include deviateing normal comparator, deviate one end input of normal comparator under circuit normal condition, the numerical value of curtage, the input of the other end is instant by the curtage value of sampler samples, result is exported to single-chip microcomputer by comparator, and output valve compares with the preset value in single-chip microcomputer, thus carries out the preliminary analysis of fault.
Further, the alarm device being connected with single-chip microcomputer includes transmission antenna, the reception antenna of remote control terminal, and alarm signal is sent by antenna, the antenna of long-range control terminal receive, the monitoring personnel of circuit judge.
Further, described circuit also includes actively disconnecting execution circuit, and antenna is respectively provided with transmission and receive capabilities；After alarm signal is sent to control terminal by antenna, controllers sends disconnecting circuit control signal by terminal, sending single-chip microcomputer to by antenna, the signal of the active disconnecting circuit of single-chip microcomputer sends to actively to disconnect and performs circuit, it is achieved to circuit active disconnecting circuit in the case of having early warning.
Further, for making can hear seen from scene alarm signal, described alarm device is made up of monolithic processor controlled buzzer and numerical control display screen；Then jump signal is carried out alarm by buzzer, and deviation numerical value is intuitively shown by numerical control display screen.
Further, also include that memory element, described memory element are connected with single-chip microcomputer, when single-chip microcomputer judges that the signal that comparator is transported in single-chip microcomputer occurs abnormal, abnormal signal is transported in memory element.
Circuit is in running, any fault and problem all also exist early warning and prompting, the presentation reflected is exactly the sudden change of circuit voltage electric current, i.e. acute variation between adjacent sample values, and this change is probably once or twice, and this change is not intended that the emergency shutdown condition of switch, it is probably the fault of circuit own, it is also likely to be the initial stage early warning of the equipment fault accessing circuit, now needs the artificial or intervention of Based Intelligent Control, it is judged that whether circuit can also continue to run.The monitoring of sudden change can be greatly improved the safety coefficient of circuit, and time during especially this device is applied to the circuit automatically controlled, its effect becomes apparent from.And as the important monitoring data of circuit, the comparison of the curtage value under the curtage value of instantaneous acquiring and normal condition, it is then the deviation monitoring that carries out of normal value of the curtage value to instantaneous acquiring, as the foundation further failure cause being analyzed.By monitoring with report to the police, before fault occurs, main circuit dynamic circuit breaker will open, the damage that access device in circuit causes because of passive power-off can be avoided, reduce the rate of breakdown of circuit.
Accompanying drawing explanation
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is that the circuit of the sudden change monitoring alarm device of a kind of auxiliary circuit switch of this utility model is constituted and signal circulation schematic diagram；
Detailed description of the invention
Below this utility model is described further as follows:
A kind of sudden change monitoring alarm device of auxiliary circuit switch, including sampler, comparator, single-chip microcomputer, alarm, it is characterized in that: described sampler accesses in the circuit at switch place, the curtage signal of Fixed Time Interval Acquisition Circuit, and two groups of adjacent monitoring signals are inputed to the two ends of comparator, the monitoring of adjacent monitoring signal is the sudden change value of measuring circuit curtage, so comparator is sudden change comparator, the result of sudden change comparator sends single-chip microcomputer to, and compare with the value preset in single-chip microcomputer, when fiducial value is beyond preset value, single-chip microcomputer sends the signal starting alarm device.The change being worth by sudden change; its change is unsatisfactory for the condition of contactor positive closing; but it is a biggest fault-signal to circuit; so; the monitoring of jump signal has theoretical basis, it is necessary to the premise of enforcement, so; the device of said structure has great benefit to protection circuit, the artificial pre-judgement participating in fault.
