Description

[Detailed Description of the Invention] The invention relates to a monitoring device for an elevator, particularly an elevator monitoring device equipped with a backup display of a separate system.In recent years, with the rapid development of electrical technology, In addition, elevator monitoring equipment has also been computerized9, and central processing equipment (hereinafter referred to as CP) has been developed.
In this case, the CPU and CRT use a large number of electronic components and mechanical components, and the system is also complex. For this reason, the reliability is lower than that of a conventional monitoring AT composed of a relay and a detection diode. Also, CPU
In the event of a failure of the CRT, all displays will no longer be displayed and elevator monitoring will become impossible. If an elevator malfunction occurs during this time, not only will it be impossible to notify the staff;
Rescue and recovery 1 is delayed and has 1 xd problem.

This invention was made to solve the above-mentioned problem, and even if the CPU or CRT breaks down, there is no need to notify the staff! ξ continues the elevator monitoring by providing the minimum information, and C provides the elevator monitoring *tv* that can be performed.

Figure 1m is a schematic diagram showing an example of the elevator monitoring position A according to the present invention. In the l'ElI diagram, the gate is the Unit 1 elevator fault detection Its device and %IJib
When the eX No. 1 elevator fails, the elevator failure signals become @l'' independently of each other. 2 is the No. 1 elevator failure detection device, and 2a.

Reference numeral 2b indicates an elevator failure signal that becomes "lo" independently of each other. Reference numeral 3 indicates a backup display device, 4 indicates a CPU, and 5 indicates a memory, in which a program for obtaining a monitoring operation is stored.

6 is a CRT, and 7 is an interface, which serves as a relay for reading the failure signal VCPU of each elevator.

The second diagram is a detailed view of the backup display device 3 shown in FIG. 030b is a potential convertible signal that becomes ``0'' when ``0'', and is the No. 1 elevator fault light signal.
is the No. 1 elevator fault light signal which is "l" when the elevator fault signal 2 is "l" and becomes @01 when the signal 21 is "01". 31.32 is the light emitting diode 35.364 Nantes Gate to drive, 35.
36 are the elevator failure lights of the first car and the first car, respectively. 31.34 is a resistor, and 3F is a power supply. ◎ If no failure occurs in the capacity configured in this manner, an elevator failure signal 1a is generated.

lb, 2m, lb is ding bay @o'''H 0 follower, elevator failure signal 30m, 30b is @0'', 31m,
31b becomes 11", and accordingly, the output ffi/iode 35.36 is turned off. 0 or 1 relay fault light signal 1b, 2b is sent to CP via the interface?
The CPU 4 is to display it on the CRT 6 according to a predetermined task, but since the elevator failure signal is 1b, 2bp@o'', the elevator failure is not displayed on the CR'T6. ◎ For example, when a failure occurs in elevator No. 1, elevator failure signals 1.a and 1b both become 11@, and along with this, elevator failure detection signal 30m becomes @.
111 and 31m becomes 101. As a result, current flows from the power source 37 to the light emitting diode 35, causing the light emitting diode 3
5 lights up. Also, the elevator failure signal lb is “lo”.
CPIJ4 via interface 7 to
reads the failure detection signal 1b)l and displays on the CRT 6 that the first unit has failed according to the predetermined procedure. In this case, the interface? , CPU4 or CR
When T"6 fails and the failure indication is no longer displayed on the CRT 6, the elevator failure signal 1a is independent of lb, so l&="''l@ and the backup display tc
tGenerally turned off l-9 aircraft - elevator failure light 35 lights up. That is, if the CRT cannot display the image of the staff due to some kind of malfunction, the backup display device operates normally and transmits information to the staff. Therefore, the staff can continue to monitor the elevator, and even if a failure occurs in the elevator, they can immediately take action to rescue and restore the elevator.

In the above explanation, only the failure of the elevator was backed up, but there is no harm in backing up other signals. In addition, the backup display may be activated by the alarm % and /L/ without using the light emitting diode. It has an excellent effect in that reliable elevator monitoring can be performed even in the situation 11 where backup display is performed using 9th=V.
