Abstract

PURPOSE:To make stable control achievable without receiving any effect of high-frequency noise due to an inverter by making a switch in circuit at time of power failure and feeding an inverter circuit and a control circuit with electric power from a direct voltage source. CONSTITUTION:AC power of a power source 1 is converted into a direct current by a rectifier circuit 2, and further it is smoothened by a smoothing capacitor 4, inputted into an inverter switching circuit 5, and an induction motor 7 is driven via a motor circuit 6, thus operation takes place at the specified speed. In addition, the power source 1 comes to a dc power source 10 for a dc control circuit by a rectifier circuit 9, through which a signal control circuit 11 operates, inputting a signal from an external switch circuit 12 or outputting it to an external output circuit 13 of a brake or the like. When the power source 1 is normal, an operating switch 18 at time of power failure is being opened, keeping off any noise to the control circuit. At time of the power failure, this switch 18 is closed, thereby driving the induction motor 7. With this constitution, operation can be done without receiving any effect of high frequency noise and, what is more, operation to the nearest floor can be done at the power failure.

[In order to make the applied voltage as close as possible to a sinusoidal wave, high-speed switching is performed.
Generates a large amount of harmonic noise. On the other hand, for household use, it is sometimes used by people. In the event of a power outage, a system is used that uses batteries to drive the train to the nearest floor. In an emergency operation device using a battery,
Since two batteries supply power to the motor drive circuit and control circuits such as signal transmission circuits, the motor circuit and control circuit are connected through the battery circuit, and high-frequency switching noise generated in the motor drive circuit is transmitted to the battery. The noise enters the control circuit through the noise, and the control circuit is affected by the noise, increasing the possibility of malfunctions caused by the noise, resulting in problem 6. The present invention eliminates the problem described in 1. Even in the Nileveter, which can operate on the nearest floor during a power outage, it emits household 1.3 noise.
This is to realize an elevator control system that does not cause 1. The present invention provides a control device for a home computer that is driven by an inverter and is capable of stable control, which is affected by high frequency noise caused by the inverter.
[Structure of the Invention] (Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides an inverter circuit for supplying power to the hoisting machine of the 171 Noveta. , the operation of the elevator ↓・, - the control circuit of the control device of the various equipment used, the power outage special number, the inverter circuit and the control circuit number, the DC power supply that supplies the power, and 5 usually the inverter circuit and the control circuit. A control device for a household elevator is provided, which has an opening/closing switch that electrically insulates 7 and connects the DC power source 1 and 2 to the inverter circuit and the control circuit number 2T in the event of a power outage. (Function) Normally Electrically isolates the inverter circuit and control circuit,
By preventing the high frequency noise of the inverter circuit from being transmitted to the control circuit side, and by turning on the on/off switch in the event of a power outage, power is supplied from the DC power supply to the inverter circuit and the control circuit, thereby reducing the influence of high frequency noise on the control circuit. Embodiment 3 An embodiment of a control device for a household elevator based on the present invention will be described with reference to the drawings. The drawing shows a control device for a domestic elevator based on the present invention.
・Shows a circuit diagram of an example. AC power is supplied from a power supply and converted into DC by a rectifier circuit 2. A DC power supply circuit 3 is connected to a smoothing capacitor 4, smoothed, and input to an inverter switching circuit 5. In the inverter switching circuit 5, the voltage frequency is set according to the driving command, etc., and is inputted to the induction motor ``7'' via the motor circuit 6, and is operated at a predetermined speed. , a predetermined control voltage]-, the rectifier circuit 9 converts the current into direct current, and it becomes a direct current power source 10 for the control circuit. This power supply operates the signal control circuit 11, and the external switch circuit 12
External output circuit 1 for human power or play key etc. for signals from
Output to 3. If the power supply is lost due to a power outage, the output of the rectifier circuits 2 and 1 will be low, so the voltage of the battery 14 will be transferred to the DC power supply circuit via the power outage operation switch 18 and the rectifier 17. 3 also supplies power to 3. The voltage of the battery 14 is supplied to the control circuit power supply circuit 10 via the rectifier 15, and is sent to the control signal control circuit 11 (C). Next, the operation of the household elevator control device having the above-described configuration will be explained. A DC power source 3 for motor control is produced from a power source 1 via a rectifier circuit 2. Further, the power source whose voltage is stepped down by the transformer 8 is converted into a DC power source 10 for a control circuit by a rectifier circuit 9. Normally, the DC power supply 3 supplied from the power source is converted into a voltage frequency according to the operation command etc. by the inverter switching circuit and supplied to the induction motor 7, and the motor is operated 1. *1. ,drive. Similarly, on the control circuit side, the electric power supplied from the source J power source 1 is used to create a control power source and to output signals such as a switch signal 12 or a brake signal. At this time,
Both the positive and negative sides of the battery 14 are connected to the motor drive circuit via a power outage operation switch 17, but when the power supply is normal, the power outage operation switch 18 is open and the motor circuit is not switched. Noise is prevented from entering the control circuit via the battery circuit 14&. In addition, when the power supply decreases, power is first supplied from the battery 14 to the control circuit O through the rectifier 15, and the control circuit such as a microcomputer is activated. Then, when preparations for operating the electric motor are completed, the switch 18 for operation during power outage is turned on. Then, the inverter switching circuit 5 is driven to generate a voltage and frequency to obtain a predetermined operating speed, and the induction motor 7 is driven to drive the train to the nearest floor and release the passengers. During this power outage, the motor main circuit and the control circuit are connected via the battery 14, and switching noise may be output from the motor main circuit to the control circuit. Since the number of operations is small and the number of operations is only once, the impact is small. In addition, under normal conditions, the control circuit and the electric motor 1jljJ
Since the lines are completely isolated, switching noise of the main circuit is not emitted from the control line. [Effects of the Invention] As described above, the present invention can provide a home elevator control device that is not affected by high frequency noise caused by an elevator drive inverter and can be operated even during a power outage.
