Detailed Description
Fig. 1 is a schematic structural diagram of a cable trench fire alarm system of a large-scale substation, and fig. 2 is a schematic structural diagram of a cable trench in which the fire alarm system of the present application is installed, and as shown in fig. 1 and 2, the cable trench fire alarm system of the large-scale substation includes a sensing unit 1, an alarm unit 2, a transmission unit 3 and a monitoring unit 4. The sensing unit 1 includes a plurality of sensors 11 disposed in the cable trench 7, and at present, there are various types of the sensors 11, such as a temperature sensor and a smoke sensor, and those skilled in the art can select an appropriate sensor according to the actual situation of the cable trench, which is within the protection scope of the present application.
In order to determine the location information of the fire place, in this embodiment, each sensor is numbered, and the number has the function of identifying the identity of the sensor. Each sensor detects the fire in the cable trench in the monitoring range, and if a fire signal is detected, the sensor sends the detected fire signal and the number of the sensor to the transmission unit.
The alarm unit 2 comprises a plurality of alarm devices 21 positioned outside the cable trench 7, the alarm devices 21 are arranged corresponding to the sensors 11, and the alarm devices 21 are used for carrying out fire alarm. It should be noted that the alarm 21 is located outside the cable trench, so that the operation and maintenance personnel can quickly find the alarm 21 for alarming, and further quickly find the fire occurrence position. The alarm comprises an audible alarm, an audible and visual alarm and the like, and can be selected by a person skilled in the art according to actual needs.
In this embodiment, the alarm 21 is disposed corresponding to the sensor 11, and specifically includes dividing the cable trench into a plurality of trench partitions, each trench partition being provided with a plurality of sensors 11, and each trench partition being provided with an alarm 21 outside, and the alarm 21 in the trench partition giving an alarm if a fire signal detected by any one of the sensors 11 in the trench partition is detected. The reason why the sensors and the alarms are arranged in a one-to-many structure is that if one sensor corresponds to one alarm, on one hand, a large number of alarms are used, and the cost of the fire alarm system is increased; on the other hand, the corresponding circuit is complex, so that the installation process of the fire alarm system is complex, and the consumption of manpower and time is caused. For the above reasons, in the present application, a plurality of adjacent sensors are grouped, and the sensors in the group share one alarm device, and when any sensor in the group detects a fire signal, the alarm device will give an alarm. According to the alarm signal, the operation and maintenance personnel can quickly find the alarm for alarming, and further quickly find the position of the fire.
The transmission unit 3 receives the fire signal and the number information transmitted from the sensor 11 and transmits the received fire signal and the number information to the monitoring unit 4.
The monitoring unit 4 receives the fire signal and the number information, determines the fire occurrence position according to the number information, and controls the alarm device 21 in the fire occurrence position to give an alarm. The monitoring unit 4 determines the fire occurrence position according to the number information, and the specific implementation process comprises that the monitoring unit 4 comprises an inductor 11 information database, and the inductor 11 information database comprises information of the number, the set position, the affiliated channeling areas, the corresponding alarm 21 and the like of the inductor 11. By using the signal database of the sensor 11, the set position of the fire can be determined according to the mark number of the sensor 11, and then the fire occurrence position can be determined.
In this embodiment, the monitoring unit 4 generates a control signal to trigger the alarm 21 of the corresponding trench division area to alarm. Of course, the alarm 21 may also be connected to the sensor 11 in the trench area where the alarm 21 is located, and when any sensor 11 in the trench area receives a fire signal, the alarm 21 in the trench area is directly triggered to alarm, and the process is not controlled by the monitoring unit 4, and both of the above two ways of triggering the alarm 21 belong to the scope of protection of the present application.
The fire alarm system also comprises a mobile terminal 5, the mobile terminal 5 is in communication connection with the transmission unit 3, and the transmission unit 3 transmits a fire signal to the mobile terminal 5 while transmitting the fire signal to the monitoring unit 4. The mobile terminal 5 receives the fire signal and performs fire alarm, so that operation and maintenance personnel can receive the fire alarm at the first time.
The mobile terminal 5 is also in communication connection with the monitoring unit 4, and the monitoring unit 4 determines the position of the fire according to the number information and sends the position of the fire to the mobile terminal 5.
In the process of reaching the fire place, on one hand, the mobile terminal 5 can provide the fire place information for the operation and maintenance personnel, and on the other hand, the alarm 21 at the fire place emits sound or light to indicate the fire place, so that the operation and maintenance personnel can reach the fire place as soon as possible under the combined action of the mobile terminal and the alarm, thereby being beneficial to the control and rescue of the fire and further reducing the damage and loss caused by the fire. Of course, when the alarm 21 is out of order or the monitoring unit 4 determines that the function of the fire place is out of order, the operation and maintenance personnel can still arrive at the fire place in a short time according to the item without the failure, so that the operation and maintenance personnel can provide double guarantee for arriving at the fire place.
In this embodiment, the fire alarm system further includes a camera unit 6, where the camera unit 6 includes a plurality of cameras disposed in the cable trench 7, and each camera can collect image information in the cable trench within a monitoring range of the camera; the transmission unit 3 is also used for sending the image information collected by the camera to the monitoring unit 4; the monitoring unit 4 is also used for converting the image information into an image to be displayed.
Through the image information in the cable pit of camera collection, the condition of cable pit can be observed in real time to fortune dimension personnel, in case the conflagration takes place, fortune dimension personnel will the very first time perceive. In addition, when receiving a fire alarm, the operation and maintenance personnel can retrieve the influence information to determine whether the fire is actually occurring, thereby excluding the case where a false alarm occurs in the sensor 11 or the alarm 21. Of course, if the alarm condition really occurs, the best fire extinguishing measure can be selected in time according to the actual fire condition in the cable trench. After the fire disaster, operation and maintenance personnel can analyze the reason of the fire disaster according to the image information before and after the fire disaster, thereby avoiding the occurrence of the fire disaster.
The utility model provides a large-scale transformer substation cable pit fire alarm system divides the cable pit into the several and divides the ditch district, is equipped with the several inductor in every branch ditch district, and every inductor all contains a serial number that is used for the sign identity, and every inductor detects its monitoring range's condition of a fire. An alarm is arranged outside each ditch dividing area, any sensor in each ditch dividing area detects a fire signal, and the alarm of the ditch dividing area gives an alarm. When a fire disaster occurs, the sensor sends the detected fire disaster signal and the number of the sensor to the transmission unit; the transmission unit sends the data to the monitoring unit; the monitoring unit receives the fire signal and the number information, can accurately determine the fire occurrence position according to the number information, and controls an alarm in the fire occurrence position to give an alarm. The operation and maintenance personnel can reach the fire place in time according to the determined fire occurrence position and the alarm signal of the alarm to perform corresponding fire control and rescue, thereby reducing the harm and loss caused by the fire.
