Description of drawings
Fig. 1 shows the block diagram of the formation of embodiments of the present invention.
Fig. 2 is used for the diagram of circuit of action of instruction diagram 1.
The specific embodiment
The block diagram of Fig. 1 shows the formation of embodiments of the present invention.In this Fig. 1, lift car 1 has cage side and send words receiver 2 and emergency state button 3, and cage side send words receiver 2 to be connected in distant surveillance device 4.Then, when an emergency state calling signal that is produced by emergency state button 3 is sent to distant surveillance device 4, distant surveillance device 4 carries out dial action, send cage side words receiver 2 to be connected to the common line road network 5 of telephone line etc.In addition, distant surveillance device 4 is connected with elevator control gear (not shown), and the running state that can make elevator is by distant surveillance.
On the other hand, central monitoring position side monitor unit 6 possesses the transmission acceptance division 7 that is connected to common line road network 5, and this transmission acceptance division 7 is connected to this central side and send words receiver 8.Therefore, the operator of central monitoring position can send words receiver 8 to carry out sending with cage side the conversation of words receiver 2 by this central side when the emergency state.
The maintenance of the necessary inscape of maintenance of call function was handled control part 9, maintenance mode setting part 10, test audio output unit 11, is received sound detection unit 12 and maintenance outcome record portion 13 when central monitoring position side monitor unit 6 also possessed as the emergency state.
Maintenance handle control part 9 administer about and the cage side maintenance of sending the call function between the words receiver 2 whether to obtain guaranteeing handle.Maintenance mode setting part 10 is used for setting the maintenance pattern that can carry out the maintenance processing, has only set under the situation of maintenance pattern at this maintenance mode setting part 10, and control part 9 is handled in maintenance just can carry out the maintenance processing.Usually, though setting that should the maintenance pattern is when maintenance or under the situation of other necessity, operator by central monitoring position is undertaken by M/C, but also can or specify the date in advance and automatically set the maintenance pattern constantly or according to the remote indication from the maintenance activity personnel.
Test is sent the words test voice data that receiver 2 is made in advance with audio output unit 11 output needles to cage side.Use voice data as this test, for example, can use the voice message of ' we will carry out the maintenance of call function from now on ' etc., also can use all effect sound or melody etc. and be not limited to speech message.
Whether receive 12 pairs of transmissions of sound detection unit acceptance division 7 send the words sound that receiver 2 receives normally to judge from cage side.In order to be received sound normally, preestablish the such sound that becomes to make that people with common sense of hearing can easily discern.Therefore, perhaps inferior more than or equal to the such situation of prescribed level under the situation of volume at noise smaller or equal to prescribed level, just can not be judged to be normal reception sound.
Though control part 9 is handled in maintenance will be according to the result of determination of above-mentioned reception sound detection unit 12, to differentiate whether normally about the maintenance result of call function, this result of determination for example can record the maintenance outcome record portion 13 that is made of hard disk.Therefore, the operator of central monitoring position can be after the end of upkeep operation suitable in, make the maintenance that is recorded in this maintenance outcome record portion 13 the results are shown in display part (not shown) and confirm.
Below, according to the action of flowchart text Fig. 1 of Fig. 2.In addition, the diagram of circuit of Fig. 2 is that the processing action of handling control part 9 with maintenance is the diagram of circuit that the center is recorded and narrated.
Now, the maintenance activity personnel that suppose elevator maintenance company for example in the upkeep operation of periodicity, ride in the lift car 1 of the maintenance of call function in the time of will carrying out the emergency state, supress emergency state button.So distant surveillance device 4 carries out dial action according to the emergency state calling signal of being sent by emergency state button 3.Thus, can send emergency state calling signal to sending acceptance division 7 by common line road network 5.Then, maintenance is handled control part 9 inputs and is sent the emergency state calling signal (step 1) that acceptance division 7 receives.
At this moment, maintenance is handled control part 9 and is checked whether the setting of maintenance mode setting part 10 is maintenance patterns (step 2).Then, if be not set at maintenance pattern (in other words, if be set at normal mode), then maintenance processing control part 9 finishes the maintenance processing unchangeably with regard to maintaining the original state and does not play a role.So in this case, the operator can use central side to send words receiver 8 and cage side to send words receiver 2 to converse.
On the other hand, if set the maintenance pattern at maintenance mode setting part 10, then maintenance is handled control part 9 to test audio output unit 11 output maintenance sign ons.Thus, test with audio output unit 11 to the test that sends acceptance division 7 output sound message etc. with voice data (step 3).This voice message sends to cage side by common line road network 5 and distant surveillance device 4 and send words receiver 2, the maintenance activity personnel in the lift car 1 is propagated the output sound that send words receiver 2 from this cage side.
If the maintenance activity personnel can hear this output sound, for example send words receiver 2 to send sound about suitable message such as ' carrying out the maintenance test of the car of No. 1 equipment at present ' to cage side.This maintenance activity personnel's sound can send to by distant surveillance device 4 and common line road network 5 and send acceptance division 7.Receive sound detection unit 12 after test has been carried out the output of above-mentioned voice message with 11 pairs of cage side of audio output unit, judge whether send acceptance division 7 has normally received cage side sound (step 4).
When reception sound detection unit 12 is judged to be the sound that has normally received cage side, it is normal with regard to differentiation for call function that control part 9 is handled in maintenance, further (for example report sound to what 7 outputs of transmission acceptance division were stipulated, ' effect sound that Pi Pi ' is such), it is sent to cage side by common line road network 5 and distant surveillance device 4 send the words receiver 2 (step 5).' Pi Pi ' reports sound to the maintenance activity personnel, and just can confirm to have differentiated call function is normal situation by listening to this.With respect to this, even receive sound detection unit 12 behind the setting-up time and also represented normally to receive under the situation of judgement of cage side sound having passed through, it is call function unusual (step 6,7) that maintenance handles that control part 9 will differentiate.
Then, maintenance is handled control part 9 the differentiation result about call function is promptly arrived maintenance outcome record portion 13 (step 8) to the differentiation outcome record of step 5 or step 7.Therefore, the operator just can after time period more than needed on the display part, show and confirm and need not confirm the result of the upkeep operation that the maintenance activity personnel are carried out immediately.
Then, maintenance is handled control part 9 after the maintenance outcome record has been arrived maintenance outcome record portion 13, to sending communicating by letter between acceptance division 7 output maintenance END instruction cut-outs and the cage side, remove the maintenance pattern of setting at maintenance mode setting part 10 again, turn back to normal mode (step 9).Thus, upkeep operation finishes, and becomes the operator and can reuse central side and send words receiver 8 and cage side to send the words state that receiver 2 is conversed.
In addition, maintenance is handled control part 9 and is being differentiated (step 7) under the situation unusual for call function, be that the maintenance activity personnel are at the voice data of having heard test usefulness from central monitoring position and after central monitoring position has sent certain voice message, wait for and for a long time also not hearing from ' under the situation of reporting sound of Pi Pi ' of central monitoring position side, the maintenance activity personnel can not transfer to next number equipment and carry out upkeep operation as the processing of practical business with regard to placing so.At this moment, the maintenance activity personnel carry out upkeep operation at the investigation abnormal cause and after having removed unusually once more from step 1 beginning.If desired, the maintenance activity personnel will wait by the phone contact with the operator of central monitoring position and carry out necessary information collection etc.
In addition, in the formation of Fig. 1, though the common line road network 5 by distant surveillance device 4 and telephone line etc. has formed the conveyor line that lift car 1 and central monitoring position side monitor unit 6 are coupled together, this conveyor line also can be formed by for example dedicated line.
The formation of the said Fig. 1 in top, be at first to export constituting of the voice data made in advance with 11 pairs of cage side of audio output unit by test, rather than in the central monitoring position side to after recording from the sound of the maintenance activity personnel in the car, regenerate this sound of recording and foldback are given the such formation of maintenance activity personnel in the car.Therefore, can finish upkeep operation at short notice.
In addition, differentiating for to exist aspect the call function under the unusual situation, as long as the maintenance activity personnel can hear the voice data of self test with audio output unit 11, then can obtain such information at least: not unusual in the conveyor line that transmits from central monitoring position lateral car side.
Further, if exist meeting bring influence to upkeep operation possibility though the sound deterioration takes place repeatedly, but in the formation of Fig. 1 and since be at first by test with audio output unit 11 to the constituting of cage side output sound data, so be can the sound-inhibiting deterioration formation.
