Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail, to make those skilled in the art can implement according to this with reference to description word.
As inscribed 1, shown in Fig. 2, conventional fire control system all adopts 24V Control of Voltage.On-the-spot fire-fighting control chamber is divided in each single building of community, and Non-follow control dish is arranged in the fire protection control room of community.DC24V power supply it is provided with in Non-follow control dish, the first hand control switch and the second hand control switch, by two hand switches, DC24V power supply is derived.It is provided with fire-fighting equipment control circuit in on-the-spot fire-fighting control chamber, including coil KA4, KA5, after coil KA4, KA5 energising, malleation fan starting can be made.It is connected by wire between Non-follow control dish with on-the-spot fire-fighting control chamber, passes into DC24V electricity by what the first hand control switch may be controlled to coil KA4, pass into DC24V electricity by what the second hand control switch may be controlled to coil KA5.Owing to the voltage in the wire of erection between Non-follow control dish and on-the-spot fire-fighting control chamber is DC24V, there are many buildings community, but fire protection control room is generally provided only with a place, the circuit so connected is general longer, running voltage is DC24 volt, the voltage drop of wire is bigger, it is possible to cause that the voltage of coil KA4, KA5 does not reach the running voltage of coil, thus causes that in community, in single building, positive pressure fan can not normally start.The miscellaneous equipment of fire control system is also in like manner, so this running voltage is DC24 volt, it is possible to cause that the running voltage of a lot of equipment of fire control system is not enough, it is impossible to normal operation, cause fire-fighting cisco unity malfunction, there is hidden fire-fighting danger.
As shown in Figure 3, in order to solve drawbacks described above, this utility model provides a kind of fire control system with power source conversion function, on-the-spot fire-fighting control chamber 130 is still divided in each single building of community, Non-follow control dish 110 is arranged in the fire protection control room of community, additionally, set up a voltage cross box 120 in the fire protection control room of community, and voltage cross box 120 is arranged apart with Non-follow control dish 110.
As shown in Figure 4, Figure 5, in Non-follow control dish 110, it is provided with DC24V power supply, some hand control switches such as the first hand control switch 111 and the second hand control switch 112, by these hand switches, DC24V power supply is derived.
On-the-spot fire-fighting control chamber 130 is arranged in each single building of community, is provided with fire-fighting equipment control circuit at the scene in fire-fighting control chamber 130, for controlling the work of fire-fighting equipment.
Power supply transverse box 120 and Non-follow control dish 110 are all placed in the fire protection control room of community, and power supply transverse box 120 is connected with Non-follow control dish 110 and on-the-spot fire-fighting control chamber 130 respectively by wire；It is provided with solenoid KA1, KA2 in described power supply transverse box 120 and fire-fighting equipment controls switch, described solenoid KA1, KA2 are connected with the low-tension supply in Non-follow control dish and hand control switch, manually control switch Guan Bi and pass into low tension for solenoid KA1, KA2；Fire-fighting equipment can be made after described solenoid KA1, KA2 energising to control switch Guan Bi, thus 220V fax being passed to on-the-spot fire-fighting control chamber, directly pass into 220V electricity for coil KA4, KA5, the running voltage of energy Reliable guarantee coil KA4, KA5, it is ensured that in community, in single building, positive pressure fan can normally start.
Fire-fighting equipment also includes the equipment such as Smoke prevention blower fan, smoke exhaust fan, fire pump, is controlled also by this mode equally.So setting up voltage cross box in fire protection control room, the running voltage of a lot of equipment of reliable guarantee fire control system, normal operation, eliminate the hidden danger of fire-fighting equipment cisco unity malfunction.
As shown in Figure 6, in another embodiment, the wire connected between described power supply transverse box and on-the-spot fire-fighting control chamber arranges deicer, described deicer includes vibrator 141 and Temperature Humidity Sensor 142, wherein vibrator 141 is arranged at the top of the support 143 of wire erection, described vibrator 141 can produce different vibration altofrequencies, to remove ice on wire or water；Temperature Humidity Sensor 142 is arranged on support 143, and it is used for detecting wire ambient temperature T0With relative humidity RH0。
Described vibrator 141 is provided with high, medium and low three gear working strengths, and described vibrator 141 selects corresponding working strength according to ambient temperature and humidity.
As it is shown in fig. 7, humiture region is divided into three regions A1, A2, A3, wherein A1 region meets 80≤RH0< RH1, T1< T0≤273；A2 region meets 80≤RH0< RH1, 0 < T0≤T1；Wherein A3 region meets RH1≤RH0≤100.Wherein humidity RH0Unit be %, ambient temperature T0Unit be Kelvin K.Preferred as one, RH1=95, T1=263K.
As ambient temperature T0With relative humidity RH0It is in vibrator during A1 region and opens low gear working strength, as ambient temperature T0With humidity RH0It is in gear working strength during vibrator during A2 region is opened, as ambient temperature T0With relative humidity RH0It is in vibrator during A3 region and opens high gear working strength.
The operating frequency f and ambient temperature T of described vibrator0With relative humidity RH0Meet:
Pass through this set, vibrator can select to vibrate working strength accordingly according to different ambient temperatures and humidity, the frequency of vibration of vibrator increases along with relative humidity etc. and increases, namely relative humidity is more big, wire more easily adheres to upper water and then build-ups ice, it is therefore desirable to what vibrator was more fast vibrates the water to remove on wire in time or ice.
The service behaviour of deicer that this utility model provides is described with embodiment below.
