Detailed Description

The present invention will be further described with reference to the following drawings and examples, and embodiments of the present invention include, but are not limited to, the following examples.

Examples

Portable fire extinguisher status monitoring system, including fire extinguisher 1 and the carrier case 2 that is used for placing a plurality of fire extinguishers 1, its characterized in that, still be equipped with a plurality of monitoring module that are used for monitoring whether fire extinguisher 1 is located carrier case 2 in the carrier case 2, a plurality of be connected with monitoring module and just to installing and be used for judging the gravity sensor 3 of the powder content in fire extinguisher 1 bottom fire extinguisher 1, be connected with monitoring module and be used for carrying out the radio frequency module 4 that uploads monitoring module monitoring information, and the fire control host computer 5 of the information of uploading of receiving radio frequency module 4 through the signal receiver who matches with radio frequency module 4, wherein, fire control host computer 5 rolls the status information of fire extinguisher 1 in every carrier case 2, and every fire extinguisher 1 places the position below and all just to one gravity sensor 3.

Example 1

As shown in fig. 1 and 2, firstly, a magnet 11 is arranged at the center of the bottom of each fire extinguisher 1, then the magnetic induction switch 9 is welded on the first printed circuit board 7 through a signal wire, wherein the reserved length of the signal wire satisfies that no matter where the first printed circuit board 7 is installed on the rigid plastic mounting box 6, the magnetic induction switch 9 welded with the first printed circuit board 7 can be placed on the first mounting frame 17, a plurality of gravity sensors 3 are welded on the first printed circuit board 7 through the signal wire, and the welding requirements are the same as the requirements of the magnetic induction switch 9. STM32 series of monolithic is chooseed for use to first controller 8, weld first controller 8 and radio frequency module 4 on first printed circuit board 7, pass through modes such as screws with first printed circuit board 7 and fix on the inner wall of mounting box 6, then fix magnetic induction switch 9 and gravity sensor 3 respectively on 1 bottom central point of every fire extinguisher puts first mounting bracket 17 and the second mounting bracket 18 that corresponds mounting box 6 inside, gravity sensor 3 installation requirement satisfies when fire extinguisher 1 puts into bearing box 2, gravity sensor 3 can be fine monitors the weight of fire extinguisher 1, insert power cord one end in the first interface 10 that charges, place mounting box 6 in the bottom that bears box 2.

The collected values of several gravity sensors are input into the first controller 8 according to the weight of a brand-new fire extinguisher and the weight of the empty-shell dry powder fire extinguisher after use, and the weight of the fire extinguisher is calculated according to the national standard of the people's republic of China: GB 12515-90, the dry powder filler of portable dry powder fire extinguisher is 2-8KG, and the empty bottle weight A of dry powder fire extinguisher can be obtained simultaneously, consequently sets for the warning threshold value of gravity sensor to be A +0.5KG through first controller 8, sets for simultaneously that first controller 8 is every 20min with the information that receives upload to fire-fighting host computer 5 to numbering all positions of placing the fire extinguisher.

The other end of the power line is connected with a power supply, so that the first controller 8, the gravity sensor 3 and the like are in working states, the fire extinguisher 1 is put into the bearing box 2 at the beginning, when the carrying case 2 is filled with completely new fire extinguishers, the magnetic induction switch 9 positioned below each fire extinguisher forms a passage with the magnet 11 positioned above the fire extinguishers, and feeds back information to the first controller 8, meanwhile, the gravity sensor 3 monitors the weight of the fire extinguisher above and feeds the monitored information back to the first controller 8, the first controller 8 sends the weight information about the existence and fire extinguisher of each fire extinguisher storage position to the fire fighting host 5 with a signal receiver through the RFID radio frequency module 4 every 20min, the fire fighting host 5 is actually provided with a display screen, so that the display screen scrolls to display all information related to the location of the fire extinguisher.

When someone lifts one or more fire extinguishers 1 in one carrying box 2, the magnet 11 is far away from the magnetic induction switch 9, and the magnetic induction switch 9 is in an off state, so that the first controller 8 cannot receive related information of the magnetic induction switch 9 at the position. When someone used dry powder fire extinguisher, the inside filling powder of dry powder fire extinguisher reduces, when filling the powder and reducing to 0.5KG and below, be less than the threshold value of settlement, consequently when above-mentioned two kinds of circumstances appear, correspond on the fire engine 5 and show "do not exist" and "change", form obvious difference with whole demonstration "normal" under the normal condition, consequently the position of the unusual fire extinguisher of locking that the staff can be quick, thereby send other staff to look over and handle the fire extinguisher of relevant position.

Example 2

The monitoring device of this embodiment adopts pressure sensor 14, install pressure sensor 14 in first mounting bracket 17 position, wherein pressure sensor 14 installation satisfies and is in same horizontal atress with the gravity sensor 3 on the second mounting bracket 18 at fire extinguisher 1 state of depositing, thereby realize pressure and gravity monitoring simultaneously, come the monitoring through pressure sensor 14 whether have the fire extinguisher to place in the bearing box 2 that corresponds the position, adopt pressure sensor 14 to monitor the existence of fire extinguisher 1 simultaneously, need not be at the bottom fixed magnet 11 of fire extinguisher 1, and other detection and connected mode all are the same with embodiment 1.

In addition, in the present application, the first printed circuit board, the first controller, the first charging interface, the second printed circuit board, the second controller, and the second charging interface are completely the same, and meanwhile, the specific connection mode and the working principle of the radio frequency module, the first controller, the second controller, the magnetic induction switch, the first charging interface, the second charging interface, and the pressure sensor on the first printed circuit board and the second printed circuit board are well known to those skilled in the art, and therefore, no further description is given in this application document.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and is not a limitation to the protection scope of the present invention, but all the changes made by adopting the design principle of the present invention and performing non-creative work on this basis should belong to the protection scope of the present invention.
