Specific implementation mode
Present invention is further described in detail by 1-2 below in conjunction with the accompanying drawings：
As shown in Figs. 1-2, a kind of ladder overturning-preventing security system based on angle detection and warning function of the invention, it is main
It will be including including mainly processor chips 3, gyroscope 2, relay 1, logic judgment part, power supply E, sound-light alarm part and leading to
Believe part.
The gyroscope 2, the relay 1, the logic judgment part, the power supply E, the sound-light alarm part and
The communications portion is installed on ladder.Wherein as shown in Figure 1, the relay 1 is pressure switch formula relay, it is mounted on
On the cross bar of ladder bottommost or mounted on the bottom of ladder side straight-bar；The gyroscope 2, the logic unit
Point, the power supply E, the sound-light alarm part and the communications portion can be mounted on any position of ladder.
The gyroscope 2 is angled for detecting the ladder and horizontal plane.
The relay 1 is used to incude the weight of ascending stair personnel, to be closed or disconnect the power supply E.
The logic unit point includes the parallel circuit of AND gate AG and NOT-AND gate NG compositions.
The sound-light alarm part includes the series circuit of flash lamp L, alarm B and diode D compositions.
The communications portion includes GPRS chips.The GPRS chips for realizing security system and remote control center nothing
Line communicates.
The gyroscope is connect by single-pole double-throw switch (SPDT) K2 with the sound-light alarm sections in series；The relay 1 with
An input terminal of the AND gate AG is connected in series with；The power supply E respectively with the NOT-AND gate NG and the GPRS chips
Connection；The NOT-AND gate NG is connected in parallel with the GPRS chips；Series circuit where the gyroscope 2 and the logic
Judgment part is connected in parallel.
As preferred means, the processor chips 3 are connected with display screen, and the display screen is for showing the ladder and water
Plane institute is angled.The display is mounted on ladder convenient for the position of ascending stair operating personnel observation.
As further preferred means, the gyroscope 2 is in series with switch K1, switch K1 and the relay 1
It is dynamic.
As preferred means, the security system further includes several divider resistance R1-R4.Each divider resistance is connected on respectively
Branch road where the main components such as gyroscope, relay, AND gate, NOT-AND gate, GPRS.
As further optimization technique means, the relay 1 is pressure switch formula relay, is mounted on the ladder
On the cross bar of bottommost or mounted on the bottom of ladder side straight-bar.Further, the pressure switch formula relay
For pressure switch open in usual can guard relay, when there is operating personnel's ascending stair, relay by the normally opened contact of holding will keep
It is attracted, security system can be remained up with power supply during ensureing normal operation.
In conjunction with attached Fig. 1 and 2, by a kind of ladder overturning-preventing security system based on angle detection and warning function of the present invention
Operation principle is described in detail as follows：
When there is operating personnel's ascending stair, personal gravity makes bang-bang relay 1 be closed, so that security system is automatic
Power on E.Gyroscope 2 detects the placement angle of ladder at this time, and the detection angles value is sent to processor chips 3, locates
The detection angles value is compared by reason device chip 3 with the security standpoint threshold value of setting, and simultaneously shows the detection angles value
On display screen (not shown), observed convenient for ascending stair operating personnel.Based on above-mentioned comparison, if detection angles value is less than security standpoint
Threshold value, then processor chips 3 control single-pole double-throw switch (SPDT) K2 be maintained on safety contact position, if conversely, detection angles value is big
In security standpoint threshold value, then processor chips 3 control single-pole double-throw switch (SPDT) K2 and are maintained at alarm contact position, that is, connect acousto-optic report
The circuit of alert part, instant alerts ascending stair operating personnel.
As shown in Fig. 2, when single-pole double-throw switch (SPDT) K2 is maintained on safety contact position, NOT-AND gate NG is connected and "AND"
Door AG is not turned on, therefore communications portion does not work；After the circuit of sound-light alarm part is connected, flash lamp L, alarm B will
Action, NOT-AND gate NG are not turned on, while the circuit of communications portion (GPRS) will be connected in AND gate AG, and communications portion uses movement
The non-security information used of ladder is sent to monitoring party by public network.
In addition, when operating personnel climbs ascending stair, gravity will trigger pressure switch formula relay and power on E,
Enter work to start entire security system.Make power supply be constantly in using the self-retaining function of pressure switch formula relay to connect
Logical state, until pressure switch formula relay is triggered again when user's descending stair, to deenergization E.
The present invention is not limited to above to the description of embodiment, those skilled in the art according to disclosure of the present invention,
It need not pass through the creative work improvement and modification that be carried out on the basis of the present invention, such as differential pressure pickup and steam trap
Selection setting etc., all should be within protection scope of the present invention.
