Description
Technical Field
The invention relates to a remote real-time monitoring system for fire extinguishers in a transformer substation, and belongs to the field of fire extinguisher management.
Background
In the transformer substation room, fire extinguishers play an important role. In order to ensure that the fire extinguisher does not fail, the fire extinguisher box needs to be opened periodically to check the fire extinguisher, and the check period is usually one month. In the process of checking the fire extinguisher, it is possible to touch the pressure part of the fire extinguisher, causing damage to the exterior of the fire extinguisher (see fig. 2). If the fire extinguisher is provided with a pressure gauge, the pressure of the fire extinguisher needs to be checked whether the pressure of the fire extinguisher is in a qualified range. If the fire extinguisher is not provided with a pressure gauge, the fire extinguisher is qualified by weighing. For example, in a 220kV substation, hundreds of fire extinguishers are usually installed, and if the fire extinguishers are checked once, a lot of time and labor are consumed, and omission is easily caused.
At present, the mainstream fire extinguisher inspection method is to manually inspect the pressure or weight of the fire extinguisher one by one. Methods for monitoring fire extinguishers in real time and studying and judging working conditions through weight sensing and pressure sensing technologies also appear. The disadvantages of these three solutions are:
1. the application range of the inspection method of the weight-sensitive fire extinguisher is limited: for the inspection of the carbon dioxide fire extinguisher, whether the fire extinguisher leaks or not can be judged through the change of the weight, but the weight of the dry powder fire extinguisher which leaks through the pressure does not change obviously.
2. The pressure sensing type fire extinguisher inspection method is a fragile fire extinguisher: when the fire extinguisher is used or checked, the fire extinguisher box needs to be opened, and in the process of opening the fire extinguisher box, the pressure gauge part of the fire extinguisher is possibly touched, so that the pressure sensor is easy to break down or damage, and the sampling data is inaccurate.
3. The fire extinguisher is manually checked one by one, the problems of overlong patrol time, low efficiency and missing patrol exist, the patrol maintenance period is too long, and the fire extinguisher is usually checked once a month, so that the change of working conditions such as the pressure of the fire extinguisher and the like cannot be found in real time.
Patent "fire extinguisher pressure on-line data acquisition device" with publication number CN203989648U discloses a data acquisition device including a plurality of fire extinguishers, a plurality of front-end devices and a monitoring backstage. The front-end equipment is in one-to-one correspondence with the fire extinguishers and comprises a digital pressure gauge and a wireless transmitting module, and the digital pressure gauge and the wireless transmitting module are connected through data lines. The digital pressure gauge is arranged on the fire extinguisher and used for detecting the pressure value of the fire extinguisher. The monitoring background comprises a wireless receiving module, a numerical value comparator and an alarm, and the wireless receiving module and the wireless transmitting module realize wireless communication. The input end of the numerical value comparator is connected with the wireless transmitting module, and the output end of the numerical value comparator is connected with the alarm through the trigger circuit. The whole device has simple structure and convenient installation, realizes the monitoring of the pressure state of the fire extinguisher in the whole building, does not use a control chip and a program, and greatly reduces the use cost.
