Elevator detection and alarm device

Abstract

The invention discloses an elevator detection and alarm device which comprises a central processor, a sensor unit and an earthquake alarm output unit, wherein the central processor is respectively connected with the sensor unit and the earthquake alarm output unit. The elevator detection and alarm device further comprises a device fault output unit and a backup power source unit, wherein the backup power source unit is respectively connected with a main power source and the central processor through a charging and discharging control circuit, and the device fault output unit is connected with the central processor. After power failure occurs, during the instant of power failure or when the power failure and the earthquake occur simultaneously, the elevator detection and alarm device can accurately detect danger signals of the location where the alarm device is installed when an earthquake occurs and give out corresponding warning, so that latent damage risks caused by automatic device recovery when an external power grid recovers can be avoided. The elevator detection and alarm device can timely inform an owner (or an upper computer) that the device maybe have problems and needs detection and maintenance when failure occurs through self detection, and further risk of devices and users is reduced.

Description

technical field [0001] The invention relates to an earthquake control operation device for construction equipment, in particular to an elevator detection and alarm device. Background technique [0002] With the continuous development of my country's urban construction speed, there are more and more high-rise buildings, high-precision instruments and rail transit have become a common operating tool. However, most equipment and rail transit facilities do not have early warning devices. When an earthquake occurs, emergency measures can only be taken artificially, and they are in a completely passive situation. It is almost impossible to respond effectively and escape from danger in an extremely short time. Some equipment is equipped with early warning devices. Once the shaking of the building caused by the earthquake exceeds the specified value, the earthquake detector will operate. After the earthquake control operation, abnormal test operation is carried out for the equipment...

Problems solved by technology

It is impossible to judge whether the acceleration sensor and the A / D conversion circuit are invalid

[0004] Existing earthquake sensors also use mechanical vibration to detect alarm output. The alarm equipment in this way is in a standby state for a long time. In a corrosive and humid environment, the mechanical structure will inevitably be corroded. Determine whether the device is accurate and effective

[0005] There are not many devices for installing seismic detectors. The existing technology generally uses two uniaxial acceleration sensors, A / D converters, and DPS. The consistency of the sensors and the difficulty in testing the acceleration lead to high cost of the seismic sensor.
