Detailed Description
The technical solution of the present invention will be described in further detail through the following embodiments.
Example 1
The embodiment provides an intelligent alarm unit of a lightning protection junction box, as shown in fig. 1 and 2, including:
the first CAN interface circuit is used for receiving a volume adjusting instruction;
the switching value acquisition circuit is used for acquiring the state of a lightning protector, the disconnection state of a ground wire and the state of an alarm switch in the cabinet;
the intelligent voice warning circuit comprises a voice chip, an audio power amplifier and a loudspeaker, wherein the voice chip is used for outputting a warning sound signal, and the audio power amplifier is used for amplifying the warning sound signal output by the voice chip and playing the warning sound signal through the loudspeaker;
and the CPU minimum system circuit is respectively connected with the first CAN interface circuit, the switching value acquisition circuit and the intelligent voice alarm circuit, and is used for generating alarm information according to the state of the lightning protector, the disconnection state of the ground wire and the state of the alarm switch, controlling the intelligent voice alarm circuit to carry out sound alarm according to the alarm information and a preset alarm configuration file, or controlling the intelligent voice alarm circuit to adjust the volume of alarm sound according to the volume adjusting instruction.
Specifically, the alarm configuration file comprises an alarm sound form, a sound size, priority of alarm information and alarm information accuracy, and a user modifies the alarm configuration file on the upper computer according to the actual needs of the station. And after modification, sending an alarm configuration file to the CPU minimum system circuit by the upper computer, wherein the CPU minimum system circuit stores the alarm configuration file as a basis for subsequent specific alarm.
Taking the lightning protection device as an example, the sound can be "alarm sound", "lightning protection cabinet lightning protection device failure warning" or "lightning protection cabinet layer XX lightning protection device warning", etc., if there are a plurality of or a plurality of warning messages, the warning is performed from high to low according to the priority sequence of the warning, and different types of warning messages correspond to different volumes and different warning types, thereby facilitating the user to distinguish the specific warning types.
Preferably, the voice chip is NV180C, supports 190 voice messages, has a voice duration of 40 seconds, plays and stops any voice through the CPU, supports 8-level alarm volume adjustment, and can perform various alarm modes such as voice alarm, warning sound alarm, and the like.
When the intelligent alarm unit is used specifically, the intelligent alarm unit is installed in the lightning protection junction cabinet, and the accuracy of alarm information can be accurate to a combined layer; the intelligent alarm unit collects the states of all lightning protection devices in the lightning protection junction box and the states of the ground wire state alarm switches through the switching value acquisition circuit and gives an alarm according to the state information of the monitored object.
Example 2
This example differs from example 1 in that: as shown in fig. 3, the device further includes a second CAN interface circuit, where the second CAN interface circuit is connected to the CPU minimum system circuit, and is configured to receive an alarm message and send the alarm message to the CPU minimum system circuit; and the CPU minimum system circuit controls the intelligent voice alarm circuit to carry out voice alarm according to a preset alarm configuration file according to the alarm information.
