The specific embodiment
1. the installation environment on train closet doorway reaches the requirement to the dress electronic product
Safety prompter is mainly used in pointing out or warning the passenger of outside, lavatory, so it should be installed in the outside in lavatory.Fig. 1 is the installation region schematic diagram of safety prompter in the utility model, and wherein Reference numeral 3 is toilet door, and double-head arrow 4 shows the switch direction of toilet door, and 5 is door-hinge.
As shown in Figure 1, along place 1, height does not have other object about 2 meters, be the desirable installation region of safety prompter under the doorframe of toilet door.Investigate multiple passenger train, the free height of toilet door top doorframe is more than 8CM.Consider maximum applicability, must control the oneself height of safety prompter below 8CM.
As shown in Figure 1, right positions 2 (height can not be too low) if there is not other object, also is the installation region of safety prompter.But in general, usually be installed in 1 place, position.
As everyone knows, train is place crowded, high-speed motion, and safety is that the most important of train erecting equipment considered.Specific to electronic product, need in general to accomplish following some: the circuit layout of first requirement product is safe and reliable, complete safety method, high-quality components and parts detect by relevant department etc.; The second, product is installed firm, crashproof antidetonation; The 3rd, the housing of product will be selected fire proofing; The 4th, it is succinct that product is wanted, and parts are as far as possible few, and line is as far as possible few etc.
2. magnetic induction measurement is a gordian technique of safety prompter in the utility model
A key of safety prompter, be find can be accurately, reliable Detection toilet door on off state and the method pointed out.The front has been discussed by existing lockset, has been used two kinds of existing problems of method of escapement, and the contriver finds that through scrutinizing magnetic induction measurement is the best approach of detecting gate state.
Magnetic inductor also claims magnet contactor, is a kind of passive electronic on-off element that the contact is arranged, the two ends lead-in wire.When magnet during near magnetic inductor, magnetic inductor presents a kind of state; When magnet left magnetic inductor, magnetic inductor presented another kind of state.Be magnet when being toward or away from magnetic inductor, magnetic inductor two ends lead-in wire or become disconnected by logical, or by disconnected flexible.The advantages such as magnetic inductor self has simple in structure, and volume is little, is convenient to control, and service life is long especially.
Safety prompter adopts the magnetic induction measurement technology, and following advantage is arranged: first is quick on the draw reliable operation; Second without wearing and tearing, need not change door and doorframe mechanism, also do not affect the appearance; The 3rd is durable, after door switch is up to a million time, and on off state that can both the reliable Detection door; The 4th allows certain installation error, is fit to installation in enormous quantities, promotes.
Embodiment 1
Fig. 3 shows the structure of the safety prompter in specific embodiment of the utility model.Simultaneously, Fig. 2 shows installation site and the mode of this safety prompter.As shown in Figure 3, this safety prompter comprises magnetic inductor 11, magnet 12, suggestion device 13 and electric supply installation 14.Magnetic inductor 11 is as a magnet contactor, are connected with suggestion device with electric supply installation 14 respectively and are connected in its two ends, realize the switch control of magnet contactor along with magnetic inductor 11 with the variation of magnet 12 distances, with the on/off of control electric supply installation 14 to suggestion device 13, thereby realize prompt facility.Wherein:
When toilet door 3 was opened, toilet door 3 band moving magnets 12 were away from magnetic inductor 11, and magnet contactor is connected, and electric supply installation 14 is suggestion device 13 power supplies, sends the caution of voice prompt or optics.
When toilet door 3 was shut, toilet door 3 band moving magnets 12 were near magnetic inductor 11, and magnet contactor disconnects, and the supply line of electric supply installation 14 whereabouts suggestion devices 13 is cut off, and suggestion device 13 is not worked.
In order to reach better technique effect, the many-side improvement is carried out on the basis of the safety prompter that can introduce in embodiment 1, becomes more practical safety prompter technical scheme.Fig. 4 is the structural representation of safety prompter in another specific embodiment of the utility model.
