Abstract

The utility model relates to a lamp abnormity monitoring device. The lamp abnormity monitoring device comprises a current sampling module (1) for detecting working current of a lamp (4), a comparing module (2) for judging whether the working current of the lamp detected by the current sampling module (1) is normal, and a result output module (3) for outputting judging results of the comparing module (2). The comparing module (2) is respectively communicated with the comparing module (2) and the result output module (3) by a circuit. The lamp abnormity monitoring device can carry out real-time monitoring on whether the lamp works normally, can continuously detect the abnormity of the lamp at any time and can send (acoustic, photic and electric) alarm signal when the lamp works abnormally, thus improving the reliability of the lamp and being fairly easy to be popularized with a simple, convenient and easy method.

Description

Light abnormality monitoring device

technical field

The utility model relates to a monitoring device which sends out an alarm signal when a lamp is abnormal.

Background technique

After the lamp has been working for a period of time, due to factors such as poor contact or damage to the lamp, damage to the rectification power supply circuit of the lamp, etc., the lamp does not light up when the lamp should normally emit light, which is hereinafter referred to as abnormal lamp. The most dangerous situation is: if the traffic hazards (such as the dangerous land and sea reefs, etc.) are used to prompt the lights of the vehicles to break down, especially at night, it may lead to traffic accidents. At present, there is no device for real-time monitoring of whether the lamp can work normally.

Utility model content

The technical problem to be solved by the utility model is to provide a lamp abnormality monitoring device for real-time monitoring whether the lamp is working normally.

The technical solution adopted by the utility model to solve the above-mentioned problems is: a lamp abnormality monitoring device, including a current sampling module for detecting the working current of the lamp, and a comparison module for judging whether the lamp working current measured by the current sampling module is normal, and The comparison module is a result output module for outputting judgment results, and the comparison module is respectively connected with the comparison module and the result output module through lines.

The lamp abnormality monitoring device of the utility model installs a current sampling module in the power supply circuit of the lamp to be monitored, the current sampling module can sample the working current of the lamp, and the comparison module judges whether the lamp working current measured by the current sampling module is normal or not , the comparison module can be an analog circuit, or be composed of a digital integrated circuit (or electronic computer) after AD conversion, and the judgment result of the comparison module will output the monitoring result of the comparison module through the result output module through the line, which is convenient for the monitoring personnel to monitor the lamp. Working conditions and timely handling when the lamp fails.

The current sampling module can sample the working current of the lamp. It can be in various forms such as an AC-DC shunt circuit, or an AC transformer, or an AC-DC clamp ammeter.

When the comparison module judges that the working current of the lamp measured by the current sampling module is abnormal, the result output module connected to the comparison module generates a sound alarm signal, or a light alarm signal, or a text alarm signal, or a graphic alarm signal, or through an electric The signal sends an alarm signal to the alarm device connected with the result output module. The comparison results of the comparison module feed back the information to the monitoring personnel through the result output module; the result output module can generate sound alarm signals (for example, if there is a fault, a warning sound will be issued), optical alarm signals (for example, if there is a fault, the indicator light will flash), or text alarms Signals, or graphical alarm signals, or send alarm signals to other equipment connected to the device through electrical signals, etc.

The lamp abnormality monitoring device acquires information on whether the control switch of the lamp is closed by sampling from both ends of the lamp. This setting can make the lamp abnormality monitoring device automatically run when the lamp switch is closed; obviously, the power supply circuit of the lamp abnormality monitoring device is also separately set, In order to avoid the situation that the lamp abnormality monitoring device cannot monitor when the lamp circuit fails.

In summary, the beneficial effects of the utility model are: the lamp abnormality monitoring device of the present utility model can monitor whether the lamp is working normally, can detect the lamp abnormality, and send out (sound, light, electricity) alarm signals when the lamp is abnormal, The reliability of the lamp is improved, the method is simple and easy to implement, and is very easy to popularize.

Detailed ways

Referring to Fig. 1, the lamp anomaly monitoring device of the present invention installs a current sampling module 1 in the power supply circuit of the lamp 4 to be monitored, and compares the lamp operating current measured by the current sampling module 2 whether it is normal or not, and passes The circuit outputs the monitoring result of the comparison module through the result output module 3 . The current sampling module 1 can sample the working current of the lamp. When the comparison module 2 judges that the working current of the lamp 4 measured by the current sampling module 1 is abnormal, the result output module 3 connected to the comparison module 2 generates a sound alarm signal, or a light alarm signal, or a text alarm signal, or a graphic alarm signal, or send an alarm signal to an alarm device connected to the result output module 3 through an electrical signal.

The lamp anomaly monitoring device of the utility model can monitor in real time whether the lamp can work normally, and can continuously detect the lamp anomaly at any time, and send out (sound, light, electricity) alarm signals when the lamp is abnormal, thereby improving the reliability of the lamp.
