The controller controls the electronic switch to make each output channel conduct or disconnect, so that the measurement data obtained by the AD measurement module is output from the corresponding output channel; The user interface is used for user operations and displaying monitoring data; the user interface is respectively connected to the controller and the output channels of the electronic switch by signals.
[0005] The second object of the present invention is to provide a multi-channel input and single-channel output measurement method, which includes the following steps: S1.

[0014] The plurality of input channels 1 are respectively connected to signal sensors. The signal sensors can be the same type of signal sensors or different types of signal sensors. The signals collected by each signal sensor are respectively transmitted to the controller 2 through the corresponding input channels 1.
[0015] The controller 2 is used to automatically classify the signals input from each input channel 1 and control the on / off of the electronic switch 4 to ensure that the signals input from different input channels 1 can correspond to the corresponding test results, realizing flexible switching between channels.
[0016] The controller 2 can be a single-chip microcomputer controller. A signal classification module and an electronic switch channel control module are built in the single-chip microcomputer controller. By setting the signal classification module, the signals input from the plurality of input channels 1 can be classified, and the classified signals are sent to the AD measurement module 3 for signal processing. Because of the different classifications of the signals, different processing methods are applied to the AD measurement module 3. Through this setting, different signals can be processed according to the corresponding processing methods respectively, and measurement data can be obtained. By setting the electronic switch 4 channel control module, the conduction and disconnection of each output channel 5 can be controlled, so that the obtained measurement data can be sent to the user interface 6 through the corresponding output channel 5.
[0017] The AD measurement module 3 is used to process the classified input signals, obtain measurement data, and transmit the measurement data to the electronic switch 4. Different types of input signal processing modules are built in the AD measurement module 3, and different types of signals are processed according to the corresponding processing modules to obtain measurement data.
[0018] The electronic switch 4 is connected to the controller 2. The electronic switch 4 is controlled by the controller 2 to make each output channel 5 conduct or disconnect, so that the measurement data obtained by the AD measurement module 3 is output from the corresponding output channel 5; The user interface 6 is used for user operation and displaying monitoring data; the user interface 6 is respectively signal-connected to the controller 2 and each output channel 5 of the electronic switch 4.
[0019] The user interface 6 can be a touch screen display, on which an intuitive and simple user interface can be designed, enabling users to easily view the measurement results of each channel.
[0020] The multi-channel input and single-channel output measurement method of the present invention includes the following steps: S1. Collect monitoring signals through multiple signal sensors; S2. The collected monitoring signals are respectively transmitted to the controller through the corresponding input channels, and the controller automatically classifies the collected monitoring signals; S3. The classified monitoring signals are respectively sent to the AD measurement module. The AD measurement module processes the signals to obtain measurement data and outputs the measurement data to the electronic switch; S4. Control the on / off of each output channel of the electronic switch through the controller, so that the measurement data obtained by processing the input signal is transmitted to the user interface through the corresponding output channel; S5. The user can operate on the user interface and view the measurement data corresponding to each input channel.
[0021] For the multi-channel input and single-channel output monitor of the present invention, only one AD measurement module needs to be set, instead of setting an AD measurement module respectively corresponding to each input channel, which greatly reduces the manufacturing cost of the monitor; the present invention can expand the functions of the monitor, collect and process multi-channel data, ensure that the collected signals are output from the corresponding output channels, and are displayed on the user interface according to different channels, improving the accuracy and convenience of data query.
