Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings. The following content is only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0020] Such as figure 1 As shown, a remote communication module interface extender of an electricity information collection device in the present invention includes a boost power supply module, an electrical isolation module, a host 485 circuit module, a step-down power supply module, and a slave 485 circuit module, wherein:
[0021] The boost power supply module boosts the interface power supply of the power consumption information collection device to 30V to supply power for the slave machine of the interface extender. The interface power supply of information collection equipment has multiple voltage levels of 4V, 5V, and 12V.
[0022] The electrical isolation module electrically isolates the ...
