Detailed Description
The intelligent guardrail for the construction site provided by the utility model is further described in detail with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent in light of the following description. It is to be noted that the drawings are in a very simplified form and are not to precise scale, which is merely for the purpose of facilitating and distinctly claiming the embodiments of the present invention.
Example one
As shown in fig. 1 to 5, the present embodiment provides a smart barrier for construction sites, which includes a barrier panel 1 and an upright 2.
Two connecting bolts 4 with downward plugs are arranged on two sides of the guardrail panel 1, certainly, 3, 4 or 1 connecting bolt can be arranged on each side and are usually arranged to be 2, the end part of each connecting bolt 4 on each side is provided with a magnet 3, and when the number of the connecting bolts 4 on each side of the upright stanchion 2 is 2 or more, at least one end part of each connecting bolt 4 is provided with a magnet 3.
The side part of the upright rod 2 is provided with a connecting sleeve 6 matched with the connecting bolt 4; the connecting sleeve 6 is provided with a magnetic reed switch 5 matched with the magnet 3, the magnetic reed switch 5 is a normally open switch and is in a disconnected state in an initial state, when the magnet 3 is close to the magnetic reed switch 5, for example, when the distance between the magnet 3 and the magnetic reed switch 5 is 10cm, the magnetic reed switch 5 is closed, and when the magnet 3 is far away from the magnetic reed switch 5, the magnetic reed switch 5 is restored to the disconnected state. An alarm 7 is arranged on the vertical rod 2; when the magnetic reed switch 5 is switched off, the alarm 7 gives an alarm, and the alarm 7 can give an alarm by sound, light or sound and light.
The intelligent guardrail for the construction site provided by the embodiment has the advantages that when the connecting bolt 4 with the magnet 3 is inserted into the connecting sleeve 6 provided with the magnetic reed switch 5, the magnetic reed switch 5 is closed, the alarm 7 does not work, when the connecting bolt 4 is pulled out of the connecting sleeve 6, the magnet 3 is far away from the magnetic reed switch 5, the magnetic reed switch 5 is disconnected, and the alarm 7 gives out sound or/and light alarm. Therefore, the intelligent guardrail can monitor the connection condition of the guardrail panel 1 and the upright rod 2 in a construction site, and prevent field personnel from detaching the guardrail panel 1 to enter an area enclosed by the intelligent guardrail.
In order to save costs, a plurality of reed switches 5 can share one alarm 7. However, if two uprights 2 share one alarm 7, the lines need to be connected between the uprights 2, which reduces the construction efficiency and is not beneficial to distinguishing which upright 2 has a problem. Preferably, the reed switches 5 on two sides of the same vertical rod 2 share one alarm 7, the alarm 7 is arranged at the top of the vertical rod 2, the power supply 10 is arranged in the vertical rod 2, and each vertical rod 2 has an independent circuit.
Fig. 6 shows a monitoring circuit for explaining the working principle of the intelligent guardrail. The monitoring circuit comprises a power supply 10, a first circuit 20 and a second circuit 30. The first circuit 20 comprises a circuit switch 21, a resistor 22 and the reed switch 5 which are sequentially connected in series; the second circuit 30 comprises an alarm 7 and a triode 31. The second circuit 30 is configured to cause the alarm 7 to emit warning information when the circuit switch 21 of the first circuit 20 is closed and the reed switch 5 is open. The power supply 10 supplies power to a first circuit 20 and a second circuit.
The specific connection mode of the monitoring circuit is as follows: the positive pole of the power supply 10 is connected with the first end of the first circuit 20, and the second end of the first circuit 20 is connected with the negative pole of the power supply 10; the first circuit 20 comprises a plurality of reed switches 5 on the same vertical rod 2, and the reed switches 5 are sequentially connected in series; the first end of the alarm 7 of the second circuit is connected with the first end of the resistor 22, the second end of the alarm 7 is connected with the collector of the triode 31, the base of the triode 31 is connected with the second end of the resistor 22, and the emitter of the triode 31 is connected with the negative electrode of the power supply 10. It can be seen that the first circuit 20 is a control circuit for controlling whether the second circuit is in operation, i.e. whether the alarm 7 is in operation.
It should be noted that the transistor 31 includes a base, a collector, and an emitter, and in this embodiment, the transistor 31 performs two functions of amplifying current and switching. As shown in fig. 6, when the circuit switch 21 and the two reed switches 5 are closed, current passes through the resistor 22 and the reed switch 5, the voltage at the base of the transistor 31 is low (usually, the voltage difference between the base and the emitter is less than 0.6V), the transistor 31 is in an off state, the current passing through the base is 0, and thus the current passing through the collector and the emitter is also 0, and the alarm 7 does not operate. When the circuit switch 21 is closed and only one of the two reed switches 5 is opened, the base electrode is high voltage, the triode 31 is in an open state, the base electrode of the triode 31 has current, the emitter and the collector of the triode 31 both have current flowing through, and the alarm 7 gives an alarm. Of course, the circuit is only a circuit diagram that the reed switch 5 is a normally open switch, and when the reed switch 5 is a normally closed switch, the alarm 7 can be directly connected in parallel with all the reed switches 5 connected in series, and at this time, the triode 31 does not need to be arranged.
Example two
The embodiment is an improvement on the basis of the first embodiment, and the improvement points are as follows: the vertical rod 2 is also provided with a transmitter 8, and the transmitter of the intelligent guardrail is connected with a server 9 matched with the transmitter. The emitter 8 is used for emitting signals when the reed switch 5 is turned off, and the server 9 is used for receiving the signals emitted by the emitter 8 and identifying the vertical rod 2 where the emitter 8 is located according to the received signals. The present embodiment further determines, via the transmitter 8 and the server 9, which particular pole 2 is in question with respect to the barrier panel 1. The pole setting 2 is numbered, the emitter 8 has a unique serial number, the serial number of the pole setting 2 corresponds to the serial number of the emitter 8, when the intelligent guardrail is installed, the pole setting 2 is preferably installed according to the serial number sequence, the emitter 8 is identified by the server 9, the serial number of the pole setting 2 is determined, and the pole setting 2 with problems can be quickly found on a construction site according to the serial number of the pole setting 2.
Referring to fig. 7, the present embodiment also shows a circuit diagram, which is different from fig. 6 in that a second circuit in the circuit diagram comprises an audible and visual alarm 7' and a transmitter 8 connected in parallel. The server 9 is used for receiving the signals transmitted by the transmitter 8. The audible and visual alarm 7' comprises a light emitting diode and a buzzer connected in parallel, and the operation principle of the second circuit is similar to that in fig. 6, and will not be described.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
