The radio, etc., thereby receiving the security signal transmitted from the sensor 42.

The security host 40 is provided with a communication unit 406, which can be connected to the control center 46 via a wired or wireless network, and can transmit the signal converted by the message processing unit 407; and the security host 40 is connected to the control center 46. The message generated by the host 40 can be processed by the message processing unit 407, including the display content, converted into a displayable message, and displayed on the display device.

It is worth mentioning that the display device provided on the security host 40 can be a kind of pointing device, and does not exclude the function that the light signal or the specific screen can be used as the status indication, and can be used to display the power state according to the indication message. In addition, the display device can display more complex information with richer content, such as messages generated by graphics, text or a combination thereof.

Figure 5 then shows an embodiment of a process for the security master to detect power.

In this creation, the security host has a power detection unit that can detect the state of the supplied power, is connected to an external backup power source, and obtains power information such as voltage according to the electrical signal carried on the connection line with the backup power source, as in step S501. Then, the state of the power output of the standby power source can be calculated, as in step S503.

The relevant circuit in the security host may be provided with a threshold value for reporting. In step S505, it is determined whether the voltage of the external power is lower than a voltage threshold.

If the detected voltage value is not lower than the voltage threshold (No), it indicates that the external standby power supply is in a normal state, and the uninterruptible power supply can be normally provided. The step returns to S501 to continue to obtain power information and judge the same. status.

If the detected voltage is lower than the voltage threshold (Yes), indicating that the power service is not normally provided, the security host converts the message into information displayed on the display device and displays it (step S507), and displays the content. In addition to the battery condition (voltage value) and the charging status, the display content may include the network connection status, the sensor information, and the maintenance of the host operating status. The message can be sent out if necessary, as in step S509, including delivery to the control center.

Therefore, the maintenance host and system with the power warning function described in the present disclosure mainly enable the security host to obtain the power state of the external backup power source, such as voltage, at any time during operation, thereby judging the status of the power supply. For example, the battery life, battery charging status, power status, etc. can be known by voltage, and the power information can be converted into a message displayed on the display device, or the control center can be notified, and the display content includes a security host and a control. The connection status of the center and the sensor signal generated by the security host. Therefore, the security host can obtain the state of the standby power supply, and can provide early warning to avoid the security problem that the security host cannot be operated when the power is turned off.
