Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as restriction of the present utility model.
As shown in Figure 1, the warning circuit of a kind of real-time monitoring fire omen early warning, comprises testing circuit, is arranged at the preposition place of electrical equipment and/or cable and wire, in order to obtain the status information of electrical equipment and/or cable and wire;
At least one remote monitoring end, remote monitor is carried out in order to right electrical equipment and/or cable and wire, wherein: also comprise a communication module, being connected to testing circuit and remote monitoring end, sending status information for status information being converted into the communication signal matched with messaging format to remote monitoring end.
Principle of work of the present utility model is: testing circuit obtains the status information of electrical equipment and/or cable and wire; Communication module, is converted into the communication signal matched with messaging format and sends status information to remote monitoring end by status information.Remote monitoring end receiving status information also shows.Remote monitoring end can be a mobile terminal, the form of status information one note is sent to mobile terminal, even if monitor staff is not at Control Room, also the status information of monitored object can be obtained at any time by mobile terminal, once find that monitored device is run wrong, failture evacuation can be carried out in time, thus avoid accident to occur, this mobile terminal also can be placed in fire department simultaneously, once there is fire the condition of a disaster, fire fighter can obtain information the very first time, and rushes towards field rescue, avoids the loss of great property.
As further preferred embodiment, as shown in Figure 2, Figure 3, Figure 4, communication module comprises a SIM900 chip, and one and the SIM card holder that matches of SIM900 chip.Adopt SIM900 chip, status information can be converted into the messaging format information matched with it and be sent to remote monitoring end.Be conducive to the text realizing status information, facilitate monitor staff to obtain the status information of monitored object.
As further preferred embodiment, also comprise the first resistance R1, the second resistance R2, the 3rd resistance R3, the 4th resistance R4, the first resistance R1 is connected to the VDD EXT pin of SIM900 chip and a PRESENCE pin of SIM card holder; Second resistance R2 is connected to the SIM VDD pin of SIM900 chip and the I/O pin of SIM card holder; 3rd resistance R3 is connected to the SIM RST pin of SIM900 chip and the RST of SIM card holder; 4th resistance R4 is connected to the SIM CLK pin of SIM900 chip and the CLK of SIM card holder.Also comprise the 5th resistance R5, connect the I/O pin with the second resistance R2 and SIM card holder.The resistance of the 3rd resistance R3, the 4th resistance R4, the 5th resistance R5 is 22 Ω.The resistance of the 7th resistance R7 is 300 Ω.The resistance of the 8th resistance R8 is 1K Ω.
As further preferred embodiment, also comprise capacitive branch, be connected between the VBAT pin of SIM900 chip and power supply ground.
