Abstract
Provided is a counter capable of predicting the service life of an electric actuating mechanism. The counter calculates the maintenance-free service life of the electric actuating mechanism by detecting the operation status of the electric actuating mechanism in real time. The counter comprises a counting module, a detecting module, a data processor, and a display module and remote interface. The counting module detects the number of the starts of a motor. The detecting module detects the accumulative operation time and the once operation time of the motor. The detecting module is connected with the data processor which is connected with the display module and remote interface. The remote interface is a network interface based on a wired network interface card or a wireless network interface card or a serial or parallel data transmission interface with various types.
Description
Technical field
A kind of counting assembly is specially a kind of electric operator counter in serviceable life that is used to detect.
Background technology
Automatically control promptly is that manually-operated is substituted by machinery or automation equipment.Can play " interface " effect between control system and the valve mechanical motion as the electric operator of one of automatic control equipment, electric operator has designing requirement on security and the reliability.Yet the environment for use of electric operator is very complicated, and can change according to the environment for use difference serviceable life of electric operator.There is serviceable life during design and actual life error.
The utility model content
Technical problem to be solved in the utility model provides a kind of measurable electric operator counter in normal serviceable life, by the operation conditions of real-time detection electric operator, calculates non-maintaining serviceable life.
In order to achieve the above object, the technical solution of the utility model provides a kind of electric operator lifetime counter, comprise and detect the electric motor starting number of times and detect the motor Cumulative Elapsed Time and detection module, data processor, display module and the remote interface of single operation duration.Detection module is connected with data processor, and data processor connects display module and remote interface.Display module is all kinds of display device, and remote interface is based on the network interface of wired network adapter or wireless network card or all kinds of string, parallel data transmission interface.
Detection module comprises A/D output counter, A.C. contactor or scr promoter counter, motor operating current CT sensor.During electric motor starting, detection module detects that electric motor starting number of times, motor Cumulative Elapsed Time comprise that motor just changes, counter-rotating and stall accumulated time, and described motor single operation duration refers to the averaging time and the maximum duration of motor single operation.
Analysis-by-synthesis was calculated after described data processor referred to detect above-mentioned data, and compared with the master pattern data, calculated lifetime data.Lifetime data comprises, parameters such as accumulative total number of run, accumulated running time, average duration, residual life value, life curve, and output interface and remote interface are included.Also can export pulpit and remote server to by remote interface.
The electric operator lifetime counter that the utility model proposed is by receiving from control panel A/D control signal, contactor actuating signal, current of electric information, and comprehensive computing changes into the information and the trend of reflection topworks operation life through counter.This information can show by display module simultaneously, and is sent to remote server, realizes the initiative monitoring to field apparatus.

As shown in Figure 2, data processor comprises CPU, and CPU connects memory module and real time clock by the I2C bus, and CPU links to each other with described comparer device by the USART bus, and CPU also connects display module and current control module respectively.
In this preferred embodiment of the present utility model, CPU adopts PIC16F877A.Real time clock adopts the special-purpose realtime clock chip of I2C interface, produces accurately real time clock information such as current time for the circuit board of control device.
The EPROM memory module is selected 2 line I2C serial EEPROMs (AT24C64W chip) for use, in order to preserve user configuration information, possesses power down and does not lose function.
During electric motor starting, detection module detects that electric motor starting number of times, motor Cumulative Elapsed Time comprise that motor just changes, counter-rotating and stall accumulated time, and described motor single operation duration refers to the averaging time and the maximum duration of motor single operation.
Analysis-by-synthesis was calculated (detection is accepted data flow as shown in Figure 3) after data processor detected above-mentioned data, and compared with the master pattern data, calculated lifetime data.Data processor transfers to display module and remote interface with lifetime data.
The content that display module and remote interface received is included in parameters such as showing accumulative total number of run, accumulated running time, average duration, residual life value, life curve on topworks's display screen.
In this example of the present utility model, output interface is a LCD.Remote interface then is the network interface card of RJ-45 for connecter type.
The electric operator lifetime counter that the utility model proposed is by receiving from control panel A/D control signal, contactor actuating signal, current of electric information, and comprehensive computing changes into the information and the trend of reflection topworks operation life through counter.This information can show by display module simultaneously, and is sent to remote server, realizes the initiative monitoring to field apparatus.
