Electric device probe expansion device and expansion-probe control method of main frame

Abstract

The present invention discloses a probe expanding device of electronic equipment and a method for controlling expanding probe by the host machine, wherein the device comprises a body and a probe expanding device plug. The body is provided with a controller, a probe signal commutation circuit, a first probe socket, a second probe socket and a probe expanding device plug. A host machine determines whether the reading of expanding probe is finished and enquires the on-position state of probe through a controller of probe expanding device. The probe which is to be executed with information reading transmits a power supply enable signal through a controller for supplying power to the corresponding probe. The communication interface of corresponding probe is gated for reading probe information.When the host machine confirms that the probe information reading is finished, a probe de-electrifying command is transmitted to the controller by the host machine. The controller controls the power supply enable signal. The corresponding probe is de-electrified and the operation is finished. An interface communication connection is realized between the probe expanding device and the host machinedevice according to the invention. An inner controller analyzes command of host machine system and realizes the functions of probe identifying, working probe switching, etc. The control to various functions is conveniently and reliably executed. The automatization degree of operation is high.

Description

【Technical field】 [0001] The invention relates to a circuit device and a control method, in particular to a structure of a probe expansion device used in electronic equipment and a related control method. 【Background technique】 [0002] In the prior art, some electronic devices, such as portable ultrasonic diagnostic equipment, have only one socket for an ultrasonic probe on the host device due to their own portability requirements and structural characteristics. Such a structure increases the frequency of replacement of the ultrasound probe by the doctor during the use of the ultrasound equipment, and increases the possibility of damage to the plug of the ultrasound probe during operation. Therefore, a probe expansion device for portable ultrasonic diagnostic equipment has appeared, which is used to increase the probe interface of the system. This expansion device can reduce the replacement of the probe to a certain extent and avoid damage. [0003] The operation of the ul...

AI Technical Summary

Problems solved by technology

The external connection of high-voltage power supply is likely to cause the danger of electric shock for operators; and the high-voltage switch is expensive, which makes the cost of the whole module more expensive

[0009] In addition, the existing probe expansion device is bulky, which is not conducive to placing it on the operating table
