Description
Technical field
The invention belongs to electronic communication field, relate to a kind of elevator intelligent thing connection terminal.
Background technology
Along with the development of social economy and culture, the vertical transport instrument that this modern of elevator lives indispensable is day by day universal, and the lifting of the improvement of elevator and people's living condition, people space quality of the life is closely related.But how Lift out of order or power failure and cause the stranded situation of passenger to happen occasionally, therefore, when passenger is stranded in elevator, gets in touch to obtain rescue with the external world and just become particularly important.Now in general passenger can get in touch by several channels and the external world: 1, in some lift car, dispose telephone set, passenger can seek help to kith and kin or 110 by phone; If 2 passengers oneself have mobile phone, also can to kith and kin or 110, seek help by mobile phone, prerequisite is in hoistway, to do signal to cover; Although 3, some elevator does not have configuring telephone machine, in car, dispose intercom or the warning alarm button that can converse with machine room on duty; If 4 passengers, both without mobile phone, do not have again telephone set, intercom or alarm button in elevator, passenger can cause that lift car external staff's attention is rescued by loud calling.When receiving, passenger's kith and kin seek help after phone, generally can notify elevator customer administrative staff or the warning of dialling 110, but comrade people's police due to 110 does not have the specialized technical knowledge of elevator, receiving the seeking help after phone of passenger, rescue mode is to contact with the elevator company with professional ability (if do not possess the professional knowledge of elevator, just not take rescue again the most efficiently, only can make the stranded time lengthening of passenger, and may cause damage to lift facility); Elevator customer administrative staff, after the warning of receiving passenger, are mostly also to contact with the elevator company with professional ability.Have some elevator customer administrative staff oneself to take measures to succour, but elevator professional level is very limited, often, because rescue improper measures makes the stranded time of passenger longer on the contrary, even can causes health or psychological injury to passenger.Because information exchange between passenger and elevator professional company can not settle at one go, the calling for help information that stranded passenger sends need through secondary even three times " call " could get in touch with elevator professional company, add 110 and elevator customer administrative staff the phone of elevator company is searched and is needed the regular hour, what elevator professional company obtained elevator faults information like this fast certainly will not make the stranded time lengthening of passenger.Although have some elevators that failure monitoring device has been installed at present, can when Lift out of order, send immediately fault signal to professional elevator company, but the failure monitoring personnel of elevator company can only receive fault message, but can not know immediately in car and whether have passenger stranded.
In lift facility, conventionally utilize switching device to concrete action, for example the operation of elevator is monitored.A plurality of this supervising devices must have specific state, to implement reliably required action.Particularly in lift facility, must guarantee before elevator cage operation and all mechanical latchings that must remain closed of run duration.In EP 0,535 205, disclosed a kind of supervising device with the control device of safety chain, described supervising device have one contactless be the releasable switching device with transducer.By approaching or realizing the control to switch or transducer away from magnet.The shortcoming of this scheme is, switch or transducer be to each magnet reaction, and no matter this magnet whether correct and whether be selected switch or the definite magnet of transducer.Approach a corresponding material and be enough to produce an effective signal.But utilize suitable cost may avoid the misoperation of switch or transducer hardly.For example by artificial disturbance, or/and external control all can cause, miss release, form the threat to lift facility safe operation.
In addition, the needs based on flash appeal, require elevator call facility to have the characteristics such as MPTY, auto dialing, consider the complex environment among lift car simultaneously, the feature such as require telephone set itself also must possess tamper-proof, anti-ly to knock, anti-interference.Yet due to the complicated of elevator environment and the requirement to function aspects, most of emergencycallboxsystem can only become ornaments and fail really positive our practical problem of solution.Traced it to its cause following some:
1, the emergencycallboxsystem that elevator is provided for oneself, general transmission range can be very not long, hundreds of rice until several kilometers become its critical distance;
2, fail to realize MPTY function, as the directly call in many ways such as cab and property department, maintaining unit, Maintenance Engineer;
3, because the interference of elevator inside is very strong, the emergencycallboxsystem that in general elevator is provided for oneself, speech quality is not fine;
If 4 calling systems go wrong, maintenance is got up particularly troublesome, so a lot of elevator just becomes completely ornaments after calling system goes wrong.
Reason based on above, the manufacturer that many elevators producer starts to attempt with industrial electro phone cooperates, and in the mode of telephone set, configures whole calling system.Elevator tripartite or five square tubes words adopt wired mode at present, need special messenger on duty; Remote monitoring also adopts wired Modem, and system cost is higher, System Expansion difficulty.
