Description
Technical field
The invention belongs to the electronic communication field, relate to the emergent supporting system of a kind of elevator accident early warning.
Background technology
Along with the development of social economy and culture, the vertical transport instrument that this modern of elevator lives indispensable is universal day by day, 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 the passenger is stranded in elevator, is got in touch with the external world and just become particularly important to obtain to save.Existing in general passenger can get in touch through several kinds of channels and the external world: 1, dispose telephone set in some lift car, the passenger can seek help to kith and kin or 110 through phone; If 2 passengers oneself have mobile phone, also can seek help to kith and kin or 110 through mobile phone, prerequisite is to do signal in the hoistway to cover; Though 3, some elevator does not have the configuring telephone machine, dispose in the car can with the interphone or the warning alarm button of machine room on duty conversation; If 4 passengers had not both had mobile phone, there are not telephone set, interphone or alarm button in the elevator again, then the passenger can cause that lift car external staff's attention is rescued through loud calling.After passenger's kith and kin receive the phone of seeking help; Generally can notify the elevator customer operating personal or the warning of dialling 110; But because 110 comrade people's police does not have the specialized technical knowledge of elevator, after receiving passenger's the phone of seeking help, the rescue mode is to get in touch with the elevator company with professional ability (just not take rescue if do not possess the expertise of elevator again the most efficiently; Only can make the stranded time expand of passenger, and possibly cause damage) lift facility; The elevator customer operating personal also mostly is to get in touch with the elevator company with professional ability after the warning of receiving the passenger.Have some elevator customer operating personals oneself to take measures to succour, but the elevator professional standards are very limited,, even can cause health or psychological injury the passenger often because the rescue improper measures makes the stranded time of passenger longer on the contrary.Because information exchange can not settle at one go between passenger and elevator specialized company; The calling for help information that stranded passenger sends needs could get in touch with elevator specialized company through secondary even three times " call "; Add 110 and the phone of elevator company is searched needed the regular hour with the elevator customer operating personal, what elevator specialized company obtained elevator faults information like this fast certainly will not make the stranded time expand of passenger.Though have some elevators that the failure monitoring device has been installed at present; Can when Lift out of order, send the fault signal immediately and give professional elevator company; But the failure monitoring personnel of elevator company can only receive failure message, can not know immediately that but that whether the passenger is arranged in the car is stranded.
In lift facility, utilize switching device to concrete action usually, for example the operation of elevator is monitored.A plurality of this control monitor units must have specific state, so that implement required action reliably.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 control monitor unit with control setup of safety chain, said control monitor unit has the switching device with sensor that a no touch can discharge.Through near or realize control away from magnet to switch or sensor.The shortcoming of this scheme is, switch or sensor be to each magnet reaction, and no matter this magnet whether correct and whether be the magnet that selected switch or sensor are confirmed.Be enough to produce an actv. signal near a corresponding material.But utilize suitable cost possibly avoid the misoperation of switch or sensor hardly.For example miss release or/and external control all can cause, constitute threat the lift facility safe operation through artificial interference.
In addition,, require the elevator call facility that MPTY, automatic characteristic such as dialing are arranged, consider the complex environment among the lift car simultaneously based on the needs of flash appeal, require telephone set itself also must possess tamper-proof, resist knock, characteristics such as disturbance rejection.Yet because elevator environment complicated and to the requirement of function aspects, most of emergency calling system can only become ornaments and fail our practical problems of positive really solution.Traced it to its cause following some:
1, the elevator emergency calling system of providing for oneself, general transmission distance can be very not long, and hundreds of rice has become its critical distance until several kilometers;
2, fail to realize the MPTY function, like directly conversation in many ways such as sedan-chair case and property department, maintaining unit, Maintenance Engineer;
3, because elevator in-to-in interference is very strong, the in general elevator emergency calling system of providing for oneself, speech quality is not fine;
If 4 calling systems go wrong, safeguard special trouble, so a lot of elevator just becomes ornaments completely after calling system goes wrong.
Based on top reason, the manufacturer that many elevators producer begins to attempt with the industrial electro phone cooperates, and disposes whole calling system with the mode of telephone set.Tripartite or the wired mode of five square tubes words employing of elevator needs the special messenger on duty at present; Wired Modem is also adopted in remote monitor and control, and system cost is higher, the System Expansion difficulty.
