Description

Intelligent smoke detection alarm

Technical Field

The utility model relates to an intelligence smog detects technical field, in particular to intelligence smog detection alarm.

Background

The smoke alarm is important equipment in a fire alarm system, the traditional wired smoke alarm is in wired transmission, wiring is needed, wiring design and wiring workload are large, operation is troublesome, the installation position needs to be installed according to wiring design, and installation is inconvenient; in addition, traditional maintenance cost is high, and based on above two reasons, wired smoke detector alarm needs the wiring, and manpower and material resources cost are all very high, and the maintenance cost in later stage in addition is more troublesome and not cost-effective.

Because the smoke sensor is generally installed, the smoke sensor is low in use frequency and less in maintenance, once the existing smoke sensor falls off, fires, artificial damage and the like, the smoke sensor is difficult to find, and great hidden danger exists.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a wireless transmission and have the smoke alarm who detects whether can normally work function.

The above technical purpose of the present invention can be achieved by the following technical solutions:

the utility model provides an intelligence smoke detection alarm, includes hemispherical casing, install the upper cover on the casing, be equipped with smoke detector in the casing, smoke detector is connected characterized by with the control unit: the upper cover is provided with a test button and a test indicator light, the inner side of the upper cover is also provided with an uncovering detector, and the test button and the uncovering detector are both connected with the control unit; the control unit is connected with an acousto-optic alarm module and an intelligent networking module based on NB-IoT technology, meanwhile, the control unit is connected with a timing test module for testing whether the acousto-optic alarm module normally gives out an alarm or not at regular time, a pickup module for detecting the sound of the alarm is arranged on the upper cover, and the pickup module is connected with the control unit.

More preferably: the cover opening detector is a normally closed switch or a normally open switch, one end of the normally closed switch or the normally open switch is connected to the upper cover, and the other end of the normally closed switch or the normally open switch is connected to the shell.

More preferably: and a fire indicator lamp is also arranged in the shell and is electrically connected with the control unit.

More preferably: the control unit is set as a single chip microcomputer.

To sum up, the utility model discloses the beneficial effect who contrasts in prior art does:

the smoke alarm takes an intelligent networking module based on NB-IoT technology as a wireless transmission module without wiring, and directly walks an NB-IOT wireless network based on three operators; in the aspect of installation, the NB-IOT is convenient to install, does not need to be bound by wires like the traditional wired smoke sensor, and can be directly installed in any place; compared with the maintenance of a wired smoke sensor, the maintenance of the NB-IOT wireless smoke sensor is convenient, and the equipment can automatically report when equipment fails or data is abnormal. In the aspect of cost, the NB-IOT smoke sensor has lower cost and does not need maintenance cost and routing cost;

in addition, the upper cover is provided with a test button, a debugging button is convenient for delivery and field and maintenance tests to test whether the product can be normally transmitted and responded to alarm, and the cover opening detection sensor is used for alarming to a background after the cover opening detector senses that the cover opening detector is manually detached and falls off after the equipment is well installed and fixed, so that a platform monitoring person is informed at the first time to survey and confirm the field and ensure the normal smoke alarm of the product; meanwhile, the timing test module and the pickup module which are matched are used for opening the sound-light alarm module to give out alarm sound at regular time, and whether the equipment can work normally is determined through the pickup module.

Drawings

Detailed Description

The following provides a more detailed description of the present invention with reference to the accompanying drawings.

The utility model provides an intelligence smog detection alarm, refer to fig. 1, including hemispherical casing, install the upper cover on the casing, be equipped with smoke detector in the casing, smoke detector is connected with the control unit, the control unit adopts 51 singlechips as the master control, on cover and install test button, test indicator and fire indicator, the detector that uncaps is still installed to the upper cover inboard, test button, uncap detector and fire indicator all are connected with the control unit, the detector that uncaps can set up to normally closed switch or normally open switch, two kinds of implementation forms have, normally closed switch or normally open switch homogeneous end are connected on the upper cover, the other end is connected on the casing.

The control unit is connected with an acousto-optic alarm module and an intelligent networking module based on NB-IoT technology, the control unit is connected with a timing test module for testing whether the acousto-optic alarm module normally gives out an alarm or not at regular time, a pickup module for detecting the sound of the alarm is arranged on the upper cover, and the pickup module is connected with the control unit.

Because the intelligent networking module based on the NB-IoT technology performs data transmission through the base stations of three operators, the base station operators already build the intelligent networking module, pay for transmission, can access the Internet by analogy with the current mobile phone 3/4G when the data goes through the operator network, is low in price and wide in coverage range, and can provide improved indoor coverage, and the NB-IoT gains 20dB more than the current network in the same frequency band, which is equivalent to improving the capacity of a coverage area by 100 times; the system has the capacity of supporting massive connections, one NB-IoT sector can support 10 thousands of connections, and low delay sensitivity, ultralow equipment cost, low equipment power consumption and an optimized network architecture are supported; in addition, the standby time of the NB-IoT terminal module may be as long as 10 years, with lower power consumption.

A test button is arranged on the upper cover and connected with the singlechip; still install the test pilot lamp, the test pilot lamp also connects the singlechip, and the test button is whether can normally transmit response warning to the test product, so install on the upper cover because this button is only used for the test, thereby can not someone maloperation press the test button and take place the alert condition of wrong report when using because the upper cover is sheltered from.

In the use of reality, the utility model discloses an after intelligence smog detecting alarm installed, under the condition that does not take place the conflagration, intelligence smog detecting alarm did not send the police dispatch newspaper, when intelligence smog detecting alarm received artificial or fire damage, the detector of uncapping can detect the anomaly of alarm, carries out the remote communication through the intelligent networking module based on NB-IoT technique and informs, and the utility model discloses be equipped with regularly test module and pickup module, regularly open the audible-visual alarm module and send out alarm sound to confirm whether equipment can normally work through pickup module, guarantee the availability of alarm.

The above description is only an exemplary embodiment of the present invention, and is not intended to limit the scope of the present invention, which is defined by the appended claims.
