The elevator monitoring system is required to be able to monitor elevator status and complete daily management.
The Observation Elevators Manufacturer introduction can be divided into the function of the module: the elevator status at the time of failure; the data summary of each work cycle; daily management information. There are a lot of information that needs to be monitored when the elevator is running. The rough classification includes: door open limit switch, door close limit switch, safety touch panel, light curtain protection, hall door lock circuit, car door lock circuit; safety circuit, emergency stop circuit, limit Switch, limit switch status; drive information, call information, position information, brake status; running time, frequency, annual inspection time, maintenance history, etc.
The monitoring of the elevator can make the fault clear. As we all know, the door system is a frequent component of elevator failure. There will always be some small faults frequently occurring before the elevator fails to stop, but these small faults are often ignored because they will not cause the elevator to stop. Take the improper adjustment of the gap between the hall door lock and the door knife as an example. When the load is uneven, the door knife may collide with the door opening wheel, causing the elevator to stop suddenly, but because of the elevator's self-correction function, the elevator will be within a few minutes This type of failure is very random, so it is often not noticed, especially for elevators that run automatically, but as small failures accumulate, they will eventually lead to major failures and even the accident monitoring system will not miss these failures. It can even locate the faulty floor to save maintenance personnel's time to find the fault point. "When a fault occurs, the collection of various information will help the judgment of the fault and the prevention of the accident." As long as the targeted settings are made, all needs The information can be collected.
For the statistical content required by managers, the monitoring system can summarize different data in different categories. For example, to judge the operation status of elevators, it is mainly judged by the failure rate, and the failure rate is usually calculated by the number of failures in a period of operation. The operation times and operation times of elevators in different buildings and different purposes are very different, and it is difficult to use This kind of failure rate is used as the basis for measuring the operating status of the elevator, and it can be measured by the number of faults in the operating time or the number of operating times, and then the judgment of the operating status can be completed. The monitoring system can accurately count the operating time and operating frequency of the elevator. Data, it is much easier to solve this problem. The daily management information includes annual inspection time, maintenance costs, use of accessories, etc." The above information is very easy to collect and transmit in a system based on the control unit, some of them are/switches, and some are The internal variables used by the control program for calculation and comparison. As long as a simple specific module is installed, the available network functions can be used to complete field data collection and transmission.
