Abstract

The utility model relates to a wireless alarm device against elevator failures. Acquired signals are transmitted into a single chip microcomputer control circuit through a commonly-used power acquisition circuit, a standby power acquisition circuit and a trigger switch circuit; and the single chip microcomputer control circuit is connected to a Personal Computer (PC) through a communicated interface circuit. The device adopts a two-path power-detection automatic switching circuit and the one-touch key alarm mode, uses a single chip microcomputer as a control circuit so as to ensure power supply in case of failures and to give wireless alarms against the failures, and has simple structure, stable and reliable performance as well as strong practicability.

Description

A kind of elevator faults radio alarming device
Technical field
The utility model relates to a kind of elevator alarm device, particularly relates to a kind of elevator faults radio alarming device.
Background technology
Elevator mainly uses at skyscraper, but elevator is because of having a power failure or during et out of order, and producing to people makes troubles and alarmed, to the overcoming difficulties of clearing of a fault and personnel, might bring danger as the untimely related personnel of notice.Traditional accident warning device is to adopt phone to send alerting signal, but elevator telephone set, old weak person just can occur seeing clearly and can not use problems such as telephone set when being in power down mode or et out of order.
The utility model content
The purpose of this utility model provides a kind of elevator faults radio alarming device that adopts the two-way power supply to detect automatic switch-over circuit.
The technical scheme that the utility model adopted is such: a kind of elevator faults radio alarming device, by power supply Acquisition Circuit commonly used, backup power Acquisition Circuit and trigger switch circuit the signal of gathering is transferred to single chip machine controlling circuit, single chip machine controlling circuit is connected to PC by communication interface circuit.
By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: this device adopts the two-way power supply to detect automatic switch-over circuit, a key triggers type of alarm, with the micro controller system is control circuit, when et out of order, guarantee the supply of power supply, and to the fault radio alarming, simple in structure, stable and reliable for performance, practical.
Description of drawings
Fig. 1 is the frame assumption diagram of the utility model embodiment;
Fig. 2 is the schematic circuit diagram of the utility model embodiment.
The specific embodiment
Further specify the utility model below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 and Figure 2, a kind of elevator faults radio alarming device, by power supply Acquisition Circuit 1 commonly used, backup power Acquisition Circuit 2 and trigger switch circuit 6 signal of gathering is transferred to single chip machine controlling circuit 3, single chip machine controlling circuit 3 is connected to PC 5 by communication interface circuit 4.
Described power supply Acquisition Circuit 1 commonly used is by threephase potential transformer YB, diode D1, D2, D3, capacitor C 1, C2, C3, resistance R 1, adjustable resistance W1 forms, threephase potential transformer YB was with output in 100: 1, line voltage is that AC220V exports through threephase potential transformer YB step-down, through diode D1 rectification, capacitor C 1 filtering, the A point voltage is a high potential, output signal is connected to the 39th pin of single chip machine controlling circuit U1, and the 39th pin of single chip machine controlling circuit U1 also is a high potential, and this moment, power work commonly used was normal.When the A point voltage was 0, when just being in low level, the 39th pin of Single-chip Controlling electricity U1 also was a low level, and Single-chip Controlling electricity U1, promotes buzzer phone DY through resistance R 11 current limlitings and sends alarm sound by its 4th pin output low level through the internal processes computing.
Described backup power Acquisition Circuit 2 is by threephase potential transformer QB, diode 1D1,1D2,1D3, and resistance 1R1, electric capacity 1C2,1C3 form, and its principle of work is identical with power supply commonly used.
Switch M is normal battle of control output of electric life controller, when M is at normally closed, the expression elevator there was a mechanical failure need the maintenance, operating voltage makes photoelectric coupled circuit U2 conducting through resistance 2R1 dividing potential drop, output low level is connected to the 1st pin of single chip machine controlling circuit U1, export through single chip machine controlling circuit U1 internal processes s operation control, by the 10th of single chip machine controlling circuit U1,21,75176 transceiver U3 the 1st of 11 pin and communication interface circuit 4,2,3,4 pin connect, form the communication data driving circuit, by the 6th of 75176 transceiver U3,7 pin transfer two buses to and are connected to the RS485 communication bus, send alert data information to PC.
More than show and described groundwork of the present utility model and principal character and advantage thereof; the technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the explanation just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
