Detailed description of the invention
With embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
As shown in Figure 1, this utility model hoistway door loop short circuit detection device includes transmitting terminal 1 and receiving terminal 2, wherein, transmitting terminal 1 includes battery 11, switching value modular converter 12 and wireless transmitter module 13, and battery 11 is powered for switching value modular converter 12 and wireless transmitter module 13；Receiving terminal 2 includes supply module 21, wireless receiving module 22 and acousto-optic alarm module 23, and supply module 21 is powered for wireless receiving module 22 and acousto-optic alarm module 23.When hoistway door is opened, hall door loop is become normally open from normally off, the logical signal in hall door loop is overturn by switching value modular converter 12, and transmits the signal after upset to wireless transmitter module 13, and the signal received is sent by wireless transmitter module 13.Wireless receiving module 22 receives the signal that wireless transmitter module 13 sends, and drives sound and light alarm module 23 to carry out sound and light alarm.If hoistway door is opened, sound and light alarm module 23 does not carry out sound and light alarm, then show that hoistway door loop is shorted.
When this utility model hoistway door loop short circuit detection device is installed, transmitting terminal 1 is arranged in the switch board of elevator(lift) machine room, the two of hoistway side hall door lines is respectively connected to two inputs of wireless transmitter module 13, opens the on and off switch of transmitting terminal 1.Receiving terminal 2 is arranged on elevator car top, and in the socket of the 220V alternating current that the plug of 220V alternating current is inserted elevator car top.When using this utility model hoistway door loop short circuit detection device that hoistway door loop is detected, elevator can run from top to bottom, inspection personnel only need to artificially open each fan hall door, disconnect the electric loop of each hall door, if receiving terminal 2 sends sound and light alarm, then show that opened hall door loop is not shorted, be qualified；If receiving terminal 2 does not sends sound and light alarm, then show that there is short circuit phenomenon in opened hall door loop, be underproof.
This utility model hoistway door loop short circuit applicable height of detection device is the building within 1 km, and in this range, wireless signal will not be impacted by the height in building.User only needs that two hall door lines are accessed dischargers and can use, and either repair and maintenance person or elevator Quality Inspector can readily use this utility model hoistway door loop short circuit detection device and detect hall door loop.
As in figure 2 it is shown, hoistway door line connects input IN1 and IN2 respectively, relay K 1 is used for detecting whether input is connected.When hoistway door is closed, and i.e. hoistway door loop is connected, input IN1 and the input of IN2 no-voltage, relay K 1 exports a normally opened signal, and by normally opened signal by port Port1 and Port2 transmission to integrated circuit NE555；When hoistway door is opened, when i.e. hoistway door loop disconnects, the high voltage of input IN1 and IN2 input 110V, relay K 1 exports a normally closed signal, and by normally closed signal by port Port1 and Port2 transmission to integrated circuit NE555.
As it is shown on figure 3, when hoistway door is closed, and i.e. hoistway door loop is connected, integrated circuit NE555 does not produce concussion, and the sound and light alarm module 23 of receiving terminal 2 is not reported to the police.
When hoistway door is opened, when i.e. hoistway door loop disconnects, integrated circuit NE555 obtains and electric exports an oscillator signal from port 3, thus triggers transistor Q1 and carry out exporting high-frequency signal, is finally launched by high-frequency signal by antenna E1.As shown in Figure 4, wireless receiving module 22 is mainly made up of audion Q1, audion Q2 and integrated circuit LM368 etc..The element composition hyperfrequencies such as audion Q1 and electric capacity C1, electric capacity C2, inductance L1 receive circuit.When antenna E1 receives modulating wave, amplify through audion Q1 tuning and low-frequency component, low-frequency component sends into integrated circuit LM368 again after the preposition amplification of audion Q2, is exported by DATE end after integrated circuit LM368 amplifies shaping, and output signal enters sound and light alarm module 23.As it is shown in figure 5, output signal is from DATA end input sound and light alarm module 23, luminous tube LED0 lights, simultaneously Q3 conducting, and buzzer LS1 obtains electric alarm.The disconnection in hoistway door loop is Tong Bu with the sound and light alarm of sound and light alarm module, postpones less than or equal to 0.3 second.
As shown in Figure 6, supply module 21 includes 220V alternating current, AC transformer T1, rectifier bridge KBL406 and manostat LM317.220V alternating current input AC transformator T1, it is transformed to low-voltage AC by AC transformer T1, input after low-voltage AC rectified bridge KBL406 rectification in manostat LM317, after manostat LM317 voltage stabilizing, export 5V unidirectional current, and provide running voltage for wireless receiving module 22 and acousto-optic alarm module 23.
This utility model is not limited to above-mentioned preferred forms; those skilled in the art can draw other various forms of products under enlightenment of the present utility model; no matter but in its shape or structure, make any change; every have same as the present application or akin technical scheme, within all falling within protection domain of the present utility model.
