Description of drawings
Fig. 1 is the entire system structural representation of the utility model embodiment;
Fig. 2 is the principle assumption diagram of the system break electric alarm device of the utility model embodiment.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, the power alarm protection system of the utility model embodiment comprises uninterrupted power source 1 (being UPS (Uninterruptible Power Supply)), power failure alarm device 2, network alarming device 3, audible-visual annunciator 4, remote terminal 5.Safety defense monitoring system 6 among Fig. 1 is effective objects of this system.Described power supply is connected with network alarming device 3, and described power failure alarm device 2 is connected with network alarming device 3, and described network alarming device 3 is connected with audible-visual annunciator 4, and described remote terminal 5 and network alarming device 3 are connected by network interface.The switching value warning output interface of described power failure alarm device 2 is connected with the switching value warning input interface of network alarming device 3.
As shown in Figure 2, power failure alarm device 2 comprises power input interface 201 (being J102), power supply change-over device 202 (being M101), relay 203 (being LS101) and warning output interface 204 (being J101).Described power input interface 201, power supply change-over device 202, relay 203 and warning output interface 204 connect successively.Be connected with voltage protection diode 205 (being D101) between power supply change-over device 202 and the relay 203.M101 realizes the voltage transitions of civil power input 220V to direct current 5V, adopts the power supply change-over device of specialty; LS101 realizes the output of power failure alarm device 2 outage back switching values.Jumper wire device (JUMPER) 206 (J103) is used for often opening and normally closed pattern of selector switch amount output." COMMON " among Fig. 2 refers to common port, is meant earth signal here.
Principle of work of the present utility model is as follows: after the burst powering-off state takes place front end system, civil power input 220V disappears, UPS works on, for safety defense monitoring system and network alarming device provide power supply, to guarantee the operate as normal of safety defense monitoring system and network alarming device.Power failure alarm device triggers own inner relay switch closure after detecting the disappearance of civil power input power supply immediately, and the switching value alarm output signal amount of power failure alarm device becomes normally off by normally open.After the warning input interface of network alarming device receives the alerting signal of power failure alarm device, trigger local sound and light alarm signal, audible-visual annunciator responds this alerting signal and sends sound and light alarm, the local monitor personnel receive alert, make response, the network alarming device uploads to remote terminal with power alarm information by network simultaneously, thereby has realized the function that local and remote network is reported to the police simultaneously.The remote terminal personnel arrange the corresponding engineering personnel to carry out the front end maintenance work after receiving the power alarm information of front end site, recover the front end electric power supply and guarantee the front-end equipment long-term stable operation.
Above embodiment only is used to illustrate the utility model; and be not to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from spirit and scope of the present utility model; can also make various variations and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be defined by the claims.
