Embodiment 1

[0027] A telemetry signal input circuit includes a primary analog switch and a secondary analog switch.

[0028] The primary analog switch includes a primary telemetry signal analog switch and a primary telemetry / loop signal analog switch. When used to connect single-ended collected telemetry data, a primary telemetry signal analog switch and a primary telemetry / loop signal analog switch Both are used to connect external telemetry signals, and output telemetry signals through address selection. When used to connect telemetry data collected at both ends, the primary telemetry signal analog switch is used to connect external telemetry signals, and output telemetry signals through address selection. The level telemetry / loop signal analog switch is used to connect the external loop signal and output the loop signal through address selection.

[0029] The secondary analog switch includes the secondary telemetry signal analog switch and the secondary ground / return signal analog swit...

Abstract

The invention discloses a telemetry signal input circuit and a telemetry signal acquisition chip. The telemetry signal input circuit comprises a primary analog switch and a secondary analog switch. The primary analog switch comprises a primary telemetry signal analog switch and a primary telemetry / loop signal analog switch; and the secondary analog switch comprises a secondary telemetry signal analog switch and a secondary ground / loop signal analog switch. The telemetry signal input circuit can be used for collecting telemetry data collected at a single end and can also be used for collectingtelemetry data collected at double ends.

Description

technical field [0001] The invention relates to the technical field of high-precision temperature measurement, in particular to a remote measurement signal input circuit and a remote measurement signal acquisition chip. Background technique [0002] At present, new satellite and spaceship platforms are developed using the design idea of ​​integrated electronics. Electronic equipment is developing in the direction of modularization, standardization, integration, and miniaturization in terms of hardware, and tends to use SOC or SIP to improve the circuit implementation. System integration and reduce system power consumption. At present, the realization of the telemetry acquisition function module in the satellite platform still stays in the use of general-purpose integrated circuits to build hardware. The product function integration density is low, the volume and weight are large, and there is no competitive advantage. [0003] In view of this, propose this invention especia...
