Implement the technical solution of the utility model, have following beneficial effect: this technical scheme has realized anti-external force intrusion detection and the early warning of outdoor electricity distribution cabinet, prevent and frightened the lawless person power distribution cabinet is destroyed, thereby reduced the destructive rate of power distribution cabinet, improved operation of power networks fail safe, provide strong technical support for building intelligentized electrical network.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of the utility model intrusion detection warning device;
Fig. 2 is the scheme of installation of the utility model intrusion detection warning device.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Should be noted that, power distribution cabinet in this programme comprises cabinet and cabinet door, one intrusion detection warning device is set in the described power distribution cabinet, see also Fig. 1, Fig. 1 is the structural representation of the utility model intrusion detection warning device, as shown in Figure 1, described device comprises for the supersonic detector 1 that described cabinet (not shown) is carried out intrusion detection by ultrasonic signal, door status switch 2 for detection of described cabinet door (not shown) folding condition, be used for carrying out according to the testing result of the testing result of described supersonic detector 1 and/or described door status switch 2 main controller 3 of respective handling, be used for when described cabinet (not shown) is invaded, sending visual alarm on every side and/or when described cabinet door (not shown) is in open mode, sending the audible-visual annunciator 4 of sound and light alarm signal and be used to described device that the power supply unit 5 of power supply is provided; Wherein, described supersonic detector 1, described door status switch 2 and the audible-visual annunciator 4 of being connected are connected with described main controller 3 respectively, and described power supply unit 5 is connected with described supersonic detector 1, described door status switch 2 and the main controller 3 of being connected respectively.Need to prove, main controller comprises that to the respective handling of testing result triggering audible-visual annunciator sends the sound and light alarm signal and/or report testing result etc. to remote control center.The content of respective handling includes but are not limited to this, and the processing method to testing result in this area can be suitable at this, describes in detail no longer one by one.
In the present embodiment, described main controller 3 is chip MSP430F5438, and it has low in energy consumption, aboundresources, frequency high, and it mainly finishes management between other parts of intrusion detection warning device and control etc.
Described supersonic detector 1 integrated ultrasonic sensor should be noted that ultrasonic sensor according to the difference of structure, and generally can divide two kinds: the first is split type ultrasonic sensor, and namely transmitting terminal is what to separate with receiving terminal; The second is the integral type ultrasonic sensor, and namely transmitting terminal and receiving terminal are to integrate.In this scheme, the operation principle of this supersonic detector 1 is: if the external emission time ultrasonic signal that is 40 ± 1.5KHZ of 80 microseconds-200 microsecond of supersonic detector 1, and beginning timing, when having detected the reception signal, namely stop timing, and the time difference △ T that calculates emission and receive, for fear of emission and mutually crosstalking that reception produces, as this time difference △ T during less than minimum measuring period, this minimum sets up on their own according to user's request measuring period, what produce when then thinking to launch crosstalks, and 3 of main controllers do not process.When time difference △ T during measuring period, thinks then that the reception signal is effective greater than minimum, then calculate distance D according to formula (1)
1
Wherein, 340m/s is the propagation velocity of sound when 25 spend.
Should be noted that the distance D when stranger and/or object distance power distribution cabinet
1Less than the warning distance D
0The time, namely thinking has the external force invasion, opens immediately audible-visual annunciator, the warning distance D
0Can set in order to be applicable to the different regions power distribution cabinet situation different from the relative distance of iron guardrail by the RS232 interface of main controller, those skilled in the art should understand, and does not repeat them here.
Described door status switch 2 comprises the magnet end that is fixedly installed in described cabinet door and is fixedly installed in the inductive switch end of described cabinet.Its course of work is, if when the cabinet door is closed, the inductive switch end is because the effect of magnetic force is in closed condition, when the cabinet door is opened so that the inductive switch end lose magnetic force and cause switch conduction.This moment, main controller 3 detected the variation of this state by its I/O mouth, judged that namely the cabinet door is opened, opened immediately the power supply of audible-visual annunciator, and invasion is warned to external force.
It is worth mentioning that, if when this device has detected alarm signal, then can carry out respective handling according to the source of alarm signal.If supersonic detector 1 is reported to the police, then main controller 3 can send visual alarm by notice audible-visual annunciator 4; If door status switch 3 is reported to the police, then main controller 3 can send the sound and light alarm signal by notice audible-visual annunciators 4, further reports to the police, and the fright invasion personnel scene that speeds away is not destroyed power distribution cabinet.Under two kinds of different type of alarms, send two kinds of different alarm, embodied the warning degree and deepened along with the intensification of invasion, play the effect of successively deepening warning.
In the present embodiment, the power supply on the secondary device that power supply unit 5 adopts in the power distribution cabinet, described power supply is 12V; Because this power supply unit 5 is low in energy consumption, can the power supply of miscellaneous equipment not impacted.Need to prove, power supply unit 5 is device construction independently, does not repeat them here.
Please in conjunction with consulting Fig. 2, Fig. 2 is the scheme of installation of the utility model intrusion detection warning device, as shown in Figure 2, described supersonic detector 1 be fixedly installed in described cabinet around, be installed in respectively position 1,2,3,4; Position 5 is the installation site of door status switch 2; Described main controller 3 is built in the centre position of described power distribution cabinet, is installed as position 6; Audible-visual annunciator 4 adopts distributed mounting means, is installed in respectively position 1,2,3,4,5.
Compared to prior art, this technical scheme has realized anti-external force intrusion detection and the early warning of outdoor electricity distribution cabinet, prevent and frightened the lawless person power distribution cabinet is destroyed, thereby reduced the destructive rate of power distribution cabinet, improved operation of power networks fail safe, provide strong technical support for building intelligentized electrical network.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the claim scope of the present utility model.
