Abstract
The utility model provides an open phase protection for medical X -ray production apparatus, belongs to medical instrument technical field. The device is divided by uneven detection circuitry (1), filter rectifier circuit (2), optoelectronic isolation circuit (3), MCU control circuit (4) four bibliographic categories and forms its characterized in that: connect outside live wire and zero line to uneven detection circuitry (1) and detect, pass through filter rectifier circuit (2) again and become DC signal to give MCU control circuit (4) with the signal transmission through optoelectronic isolation circuit (3), whether MCU control circuit (4) passing signal is judged provides the protection to equipment and the suggestion of reporting to the police, simultaneously judging that the result offers PC or other relevant equipment through communication interface. Its advantage is: analog circuit and digital circuit combine together, and strong and weak electrical isolation is reliable and stable, can go deep into programming control to MCU to at any time, adjust the code as required, it is convenient nimble, the circuit is reliable and stable, and the debugging is simple, and the extension is convenient, the easily production.
Description
Technical field
This utility model belongs to technical field of medical instruments.
Background technology
At present in the open-phase protection field of medical apparatus and instruments, commonly use ready-made brand open-phase protection module, and the disconnected phase of ready-made brand
Protection module, generally requires regulation live wire line sequence, not easy to operate, and does not provide protection to neutral line break, there is potential safety hazard,
Install fixing also inconvenient.
Content of the invention
The purpose of this utility model is: invention is a kind of and ready-made brand open-phase protection module compared with it is not necessary to regulation live wire
Line sequence, and line off zero can provide the open phase protection of protection.
This utility model be the technical scheme is that this device by uneven testing circuit, filter rectifier, photoelectricity
Isolation circuit, mcu control circuit four part composition it is characterised in that: outside live wire and zero line are connected to uneven testing circuit
Detected, then rectification circuit is become direct current signal after filtering, and passed through photoelectric isolating circuit by signal transmission to mcu control
Circuit, mcu control circuit passes through whether signal determining provides protection alarm to equipment, result of determination is passed through logical simultaneously
Letter interface is supplied to pc machine or other relevant devices.
The beneficial effects of the utility model are: analog circuit is combined with digital circuit, strong and weak electric isolution, reliable and stable；
Can mcu be carried out going deep into programming Control, and adjust code as needed at any time, convenient, flexible；Circuit stability is reliable, debugging letter
Single, extension is conveniently it is easy to produce.
Brief description
Fig. 1 is a kind of theory diagram of the open phase protection for Medical X-ray machine.
Fig. 2 is a kind of uneven testing circuit schematic diagram of open phase protection for Medical X-ray machine.
Fig. 3 is a kind of filter rectification of the open phase protection for Medical X-ray machine and photoelectric isolating circuit schematic diagram.
