Problems solved by technology
When this power monitoring method is applied to some special communication occasions such as electronic medical record systems, there are the following problems: 1) If the embedded device is not with the owner, the alarm message cannot remind the owner to take measures to avoid power exhaustion; 2) The user When the power is insufficient, important information may be lost or misrepresented; 3) When the communication connection is interrupted, it is impossible to know whether the interruption is due to the shutdown of the device or the exhaustion of the power; these may lead to adverse consequences and even serious accidents
In addition, the power consumption during the alarm is too high, which is not conducive to energy saving; the fixed audio alarm information cannot meet the current needs of people pursuing personalized alarm information; it is also the deficiency of the existing technology

The invention relates to an electric quantity voice alarm monitoring device and a monitoring method for embedded equipment, and belongs to the technical field of embedded wireless communication facilities. The device comprises a storing device, a monitoring device, a comparing device, a warning device and a communication device. A first voltage threshold value is greater than a second voltage threshold value by storing the first voltage threshold value and the second voltage threshold value; detected power supply real-time voltage values are transmitted to the comparing device and are compared in a first round and a second round; and a voice frequency alarm signal is ensured to be sent, or information of electric quantity shortage is sent for a monitoring server on duty in a wireless communication manner by the voice frequency alarm signal. Therefore, not only can an equipment owner be reminded of charging by the device, but also remedial measures can be timely taken by an operator on duty when the embedded equipment is absent from the equipment owner's side. Compared with the prior art, the monitoring device and the monitoring method can provide more reliable guarantee for communication keeping on important occasions.
Description
technical field [0001] The invention relates to a power voice alarm and monitoring device, in particular to a power voice alarm monitoring device for embedded equipment, and also relates to a corresponding monitoring method, which belongs to the technical field of embedded wireless communication facilities. Background technique [0002] Currently, embedded systems such as PDAs and mobile phones all use lithium batteries as electrical energy. How to manage limited power more effectively and make better use of it has always been an important design content of embedded devices. [0003] As far as the applicant knows, the power monitoring of existing embedded devices such as PDA mainly monitors the battery power through a dedicated power management chip, and the method used is to send out a fixed alarm sound when the power is about to run out to remind the user to charge. When this power monitoring method is applied to some special communication occasions such as electronic med...
