Description
Technical field
The utility model relates to a kind of control monitor unit, specifically a kind of electric control line of tower crane power on/off recording device.
Background technology
The electric control line of tower crane integrated use sensor technology, embedded technology and data acquisition technology.Main purpose is exactly that the hoisting weight of hoisting crane is controlled.When lifting weight surpasses preset value, will produce warning and make corresponding action.At present the technology that adopts of electric control line of tower crane mainly contains two kinds of mechanical type and electronic types.Mechanical type triggers micro-switch by mechanical device and realizes the control purpose, and electronic type gathers data by sensor, realizes the control of hoisting crane after by treater data being processed afterwards by control relay.By the existing market existing product is analyzed discovery, above two schemes has mainly been realized the real-time control of tower crane, and unrealized timely record to data in the gatherer process is in order to check from now on.Based on this problem, the utility model rises to such an extent that transform on the basis of machine control system in existing electronic type, added and powered on and the power down recording device, solved the record of tower crane startup and shutdown, can inquire about at any time to such an extent that the use of machine is recorded and the time after convenient.
Summary of the invention
The purpose of this utility model provides the recording device of a kind of electric control line of tower crane power on/off, is used for the tower crane startup and shutdown time is carried out record, calculates the work-hours of hoisting crane so that the user can check the job record of hoisting crane at any time.
The utility model adopts following technical scheme to achieve these goals: the recording device of electric control line of tower crane power on/off, comprise voltage stabilizer, power-fail detection circuit, memory device, treater and RTC, wherein, described voltage stabilizer power end external source, it is anodal that the voltage stabilizer other end connects diode D, diode D negative pole is connected with processor power supply, the treater connected storage, the power end of memory device is connected with diode D negative pole, diode D negative pole is also by capacitor C ground connection, RTC is connected with treater, and an end of power-fail detection circuit is connected with treater, the other end connects the voltage stabilizer power end.
The beneficial effects of the utility model are: the utility model device can in time carry out record to the switching on and shutting down time of hoisting crane, conveniently checks the job record of hoisting crane and work-hours is added up.
Description of drawings
Device of the present utility model can further specify by the indefiniteness embodiment that accompanying drawing provides.
Fig. 1 is schematic block circuit diagram of the present utility model;
Among the figure: the 1-voltage stabilizer; The 2-power-fail detection circuit; The 3-memory device; The 4-treater; 5-RTC.
The specific embodiment
Be described further below in conjunction with accompanying drawing.
Referring to Fig. 1 functional block diagram of the present utility model, the utility model device comprises voltage stabilizer 1, power-fail detection circuit 2, memory device 3, treater 4 and RTC5, it is characterized in that: described voltage stabilizer 1 power end external source, it is anodal that voltage stabilizer 1 other end connects diode D, diode D negative pole is connected with treater 4 power supplys, treater 4 connected storages 3, the power end of memory device 3 is connected with diode D negative pole, diode D negative pole is also by capacitor C ground connection, RTC5 is connected with treater 4, and an end of power-fail detection circuit 2 is connected with treater 4, the other end connects voltage stabilizer 1 power end.Described power-fail detection circuit 2 sends to treater 4 by interrupt mode with power down information.
Mainly by the realization of micro controller system (being treater) internal processes, behind the device power voltage stabilization, SCM program can be recorded to the current time in the external memory storage power-on time writing function of the present utility model.
The hardware circuit of realizing the power down writing function comprises power-fail detection circuit 2, fast recovery diode D, chemical capacitor C etc.After device power, charge to capacitor C by fast recovery diode D, and give micro controller system and external memory storage power supply.After device looses power, power-fail detection circuit 2 is notified micro controller system by interrupt mode after detecting power-off signal, and micro controller system response power-fail interrupt writes external memory storage 3 with the power down time.In the power down process when 7805 stabilizer output voltages are lower than a certain setting voltage value, fast recovery diode D cuts off 7805 voltage stabilizer feed circuit, play buffer action, this moment, micro controller system and external memory storage were powered by capacitor C, for micro controller system record required power supply of power down time.After the capacitor C discharge finished, equipment was closed fully.The RTC unit is clock unit, for micro controller system provides correct time information.
