Description
Technical field
The present invention relates to the ultrasonic diagnosis technical field, be specifically related to a kind of channel connectivity diagnostic equipment of probe-head control module of ultrasonic diagnostic device.
Background technology
As shown in Figure 1, existing ultrasonic diagnostic equipment mainly is made up of five parts: probe-head control module, receiver module, transmitter module, beam synthesizer, digital signal processing module.Concrete realization principle is such: the pulse that transmitter module sends out is added on the wafer of probe array element, the ultrasonic pulse that wafer sends is propagated in the soft tissue of human body, after running into tissue, ultrasound wave reflects, the echo that reflects amplifies by receiver module and handles, signal after the processing uploads to computer by pci card, demonstrates image by display then.
The transmitted pulse of transmitter module arrives probe array element by behind the high-voltage switch gear through probe-head control module, and probe array element is encouraged.In this process, the probe-head control module of forwarding pulse seals to the passage of probe array element, we observe the some passages that can not find probe-head control module and whether have fault or damaged from the outside, because the passage that damages can not encourage probe array element, therefore also can't receive the signal that returns, this has just influenced the quality of ultrasonoscopy, and bad track appears in a spot of probe-head control module passage, and only the mass discrepancy from ultrasonoscopy is difficult to make judgement accurately.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of channel connectivity diagnostic equipment of probe-head control module of ultrasonic diagnostic device, overcomes prior art and can not accurately judge the defective whether the probe-head control module passage exists fault or damaged when carrying out the production test of ultrasonic diagnostic equipment.
The present invention solves the problems of the technologies described above the technical scheme that is adopted to be:
A kind of channel connectivity diagnostic equipment of probe-head control module of ultrasonic diagnostic device, comprise power supply, direct current signal generator, high-voltage switch gear, front-end control module and display module, described power supply links to each other respectively with described direct current signal generator, described high-voltage switch gear and described front-end control module, described direct current signal generator links to each other with described high-voltage switch gear respectively with described front-end control module, described high-voltage switch gear links to each other with the input of the probe-head control module of needs test, needs the outfan of the probe-head control module of test to link to each other with described display module.
Described channel connectivity diagnostic equipment of probe-head control module of ultrasonic diagnostic device is characterized in that: described direct current signal generator output multi-channel DC level.
Described DC level is made as 3.3 volts DC level.
Described high-voltage switch gear is made as four and selects a high-voltage switch gear.
Described front-end control module comprises the field-programmable unit, the signal of the described high-voltage switch gear break-make of described field-programmable unit output control.
Described display module is made as light-emitting diode display panel.
Described light-emitting diode display panel comprises the corresponding light emitting diode of port number of the probe-head control module that number and needs are tested, and described light emitting diode is connected with the passage of the probe-head control module that needs test.
The described light emitting diode resistance of also connecting.
Need the probe-head control module of test to be made as the probe panel of controlling 128 probe array elements.
Beneficial effect of the present invention is: because channel connectivity diagnostic equipment of probe-head control module of ultrasonic diagnostic device of the present invention directly applies low DC level by the passage for the probe-head control module that needs test, for the light emitting diode on the LED display panel provides drive current, when the passage of the probe-head control module of needs tests breaks down, light emitting diode is not luminous, so just whether exist fault to provide simple for the passage of judging the probe-head control module that needs test, intuitively, means efficiently, save the diasonograph testing cost, improved production test efficient.

The specific embodiment
With embodiment the present invention is described in further detail with reference to the accompanying drawings below:
As Fig. 2, Fig. 3, Fig. 4, Fig. 5 and shown in Figure 6, channel connectivity diagnostic equipment of probe-head control module of ultrasonic diagnostic device of the present invention, comprise power supply, the direct current signal generator, high-voltage switch gear, front-end control module and display module, power supply and direct current signal generator, high-voltage switch gear links to each other respectively with the front-end control module, the direct current signal generator links to each other with high-voltage switch gear respectively with the front-end control module, high-voltage switch gear links to each other with the input of the probe-head control module of needs test, need the outfan of the probe-head control module of test to link to each other with display module, display module can be made as light-emitting diode display panel, light-emitting diode display panel comprises the corresponding light emitting diode of port number of the probe-head control module that number and needs are tested, and light emitting diode is connected with the passage of the probe-head control module that needs test.The light emitting diode resistance of also connecting.The direct current signal generator is to need each passage of the probe-head control module of test to export 3.3 volts DC level, also can select to export 5 volts of DC level certainly, needs only the resistance of adjusting the light emitting diode series connection this moment.High-voltage switch gear also can be made as four and select a high-voltage switch gear.The front-end control module comprises the field-programmable unit, the signal of field-programmable unit output control high-voltage switch gear break-make.Need the probe-head control module of test to be made as the probe panel of controlling 128 probe array elements.
The mode of FPGA (field-programmable unit) control high-voltage switch gear is for all to be changed to high level with its control signal.When test set powers on, 128 passages of probe panel all are connected to the direct current signal generator of 3.3 volts or 5V DC voltage by high-voltage switch gear.
Test philosophy of the present invention is that the array element of will pop one's head in all changes light emitting diode into, to need every paths of the probe-head control module tested to apply low DC level by high-voltage switch gear, the other end of every paths connects light emitting diode, if this paths fault-free, then the lumination of light emitting diode of series connection with it can directly be observed the connectedness of judging the probe-head control module passage with eyes like this.
