As shown in fig. 1, an embodiment of the present invention provides a miniaturized SSI data acquisition system, the miniaturized SSI data acquisition system includes:

a control chip;

In the technical scheme adopted by the embodiment, the input interface module comprising the plurality of input interfaces can meet the requirement that the plurality of input interfaces are simultaneously connected with a plurality of products or systems for acquiring data. Meanwhile, the chip is directly controlled to be electrically connected through each input interface, so that the structure of the whole small-sized SSI data acquisition system is simple, and the size is small.

Further, referring to fig. 2, in an embodiment of the present invention, the miniaturized SSI data acquisition system further includes:

and the output interface is connected with the control chip.

In the technical scheme adopted by the embodiment, in order to enable the data acquisition system to be directly connected with an upper computer, namely a PC (personal computer), an output interface is also arranged, so that the direct connection of the small SSI data acquisition system and the PC is facilitated, and the requirements of different data acquisition and processing are met.

and the power supply module is connected with the control chip.

In the technical scheme adopted by the embodiment, different voltage values required by the whole system are supplied, so that the stable operation of the whole miniaturized SSI data acquisition system is ensured.

Further, in an embodiment of the present invention, the miniaturized SSI data acquisition system further includes:

In the technical solution adopted in this embodiment, in order to ensure that the connected data acquisition sensor, for example, the angle sensor, can transmit the data acquired by the angle sensor to the control chip more accurately, an encoder needs to be arranged between the input interface and the control chip.

Specifically, with the development of technology, there is a demand for higher accuracy. To meet such a demand, absolute value encoder resolution is becoming higher and higher. However, high precision requires an increase in the number of bits and the number of cable cores, thereby increasing installation costs and being prone to errors; the SSI interface has the advantages of low installation cost and simplified circuitry, and transmits position data of the absolute value encoder only in a serial manner of two signals (clock and data) regardless of the accuracy of the encoder through a serial line synchronized by a clock. The working principle of an SSI encoder is very similar to that of a standard absolute value encoder. The main parts are as follows: the device comprises a code disc formed by a luminous source transparent and non-transparent windows, a photoelectric receiver, a starting/triggering circuit, a parallel/serial converter, a monostable circuit, a clock signal input circuit and data signal output equipment. The data is read by the encoder reading system and continuously transferred to a parallel/serial converter ("conversion register" with parallel functionality). When this monostable current is activated by a clock signal transfer, data is stored and transmitted to the output with a clock synchronization signal.

and the flash memory chip is connected with the control chip.

In the technical scheme adopted in this embodiment, in order to enable the miniaturized SSI data acquisition system to transmit acquired data to the host computer in real time and to store and package the acquired data and send the data to the host computer, a flash memory chip is required to be connected to the control chip, and the acquired data is temporarily stored by the flash memory chip.

In the technical scheme adopted by the embodiment, in order to facilitate the connection of the miniaturized SSI data acquisition system and the PC without an SSI interface, a USB-to-serial port connection line is further arranged at the output port, so that the data transmission between the miniaturized SSI data acquisition system and the PC is facilitated.

Furthermore, in an embodiment of the present invention, the miniaturized SSI data acquisition system includes 4 input interfaces

Further, in an embodiment of the present invention, the input interface is a DB9 female interface. The output interface is a DB9 public interface.

In the technical solution adopted in this embodiment, the DB9 interface is a common interface and is easy to implement, and preferably, the input interface is a DB9 female interface, and the output interface is a DB9 male interface.

The above description is only a preferred embodiment of the present application, and not intended to limit the scope of the present application, and all modifications and equivalents of the technical solutions that can be directly or indirectly applied to other related fields without departing from the spirit of the present application are intended to be included in the scope of the present application.
