Abstract
The utility model discloses a wireless alarm system for combustible gas in an Ad-Hoc network. According the wireless alarm system, an output signal of a gas detecting and alarming sensor far from a control bus is transmitted to a module transmitting terminal below 1GHz; an output signal of a gas detecting and alarming sensor close to the control bus is transmitted to a 2.4GHz Zigbee module transmitting terminal; the module transmitting terminal below 1GHz and the 2.4GHz Zigbee module transmitting terminal are connected with a host machine of a controller through the control bus, and the host machine of the controller receives alarm signals of two frequencies through corresponding modules. The wireless alarm system utilizes two wireless carrier wave technologies to transmit an alarm signal and a fault signal of a combustible gas alarm on the basis of the distance between the alarm and a position where the host machine is placed through carrier frequencies of below 1GHz and 2.4GHz respectively, so as to adapt to various complicated working conditions in practical application.
Description
Technical field
The utility model relates to combustible gas alarm safety detection field, more particularly, relates to a kind of MANET wireless alarm system.
Background technology
Existing gas detecting alarm system mainly makes in two ways, and a kind of is wire communication mode, and another kind is the wireless network communication mode by telecom operators.Wire communication mode often needs to lay a large amount of sunkening cord, and not only wastes resource, safeguards also inconvenient.The reasons such as and the wireless self-networking of common single carrier wave is often large owing to the wiring difficulty, and communication effect is unreliable are difficult to promote in actual applications.For both can realizing that wireless telecommunications can also not restricted by telecom operators, and the reliable wireless ad hoc network of communication effect is also unrealized.
The utility model content
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, and a kind of MANET inflammable gas wireless alarm system of high reliability is provided.
The utility model MANET inflammable gas wireless alarm system flows to 1GHz with the lower module transmitting terminal with the output signal of the distant detection of gas alarm sensor of control bus; Flow to the Zigbee module transmitting terminal of 2.4GHz with the output signal of the detection of gas alarm sensor of control bus close together; 1GHz is connected Zigbee module receiving end with the lower module receiving end and is connected with the controller main frame by control bus respectively with 2.4GHz, the controller main frame receives respectively the alerting signal of two kinds of frequencies by corresponding module receiving end.And the distant distance that refers to of control bus refers in 1 kilometer with the control bus close together between 1 kilometer to 3 kilometers.
The utility model is by using two kinds of wireless carrier technology, with the warning of flammable gas alarm and fault-signal according to alarm and place distance between the position of host machine, respectively by launching with the 2.4GHz carrier frequency below the 1GHz, nearer for communication distance, block less node, adopt the 2.4GHz carrier frequency, stable communication effect can be provided; Far away for communication distance, block more node, adopt the following carrier frequency of 1GHz, communication distance far away can be provided, so just can adapt to the operating mode of various complexity in the practical application.
Description of drawings
Fig. 1 is the utility model theory diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the output signal with the distant detection of gas alarm sensor of control bus flows to 1GHz with the lower module transmitting terminal; Flow to the Zigbee module transmitting terminal of 2.4GHz with the output signal of the detection of gas alarm sensor of control bus close together; The following radio station of 1GHz module receiving end is connected Zigbee module receiving end and is connected with the controller main frame by control bus respectively with 2.4GHz, the controller main frame receives respectively the alerting signal of two kinds of frequencies by corresponding module receiving end.And the distant distance that refers to of control bus refers in 1 kilometer with the control bus close together between 1 kilometer to 3 kilometers.
Nearer for communication distance, block less node, adopt the 2.4GHz carrier frequency, stable communication effect can be provided; Far away for communication distance, block more node, adopt the following carrier frequency of 1GHz, communication distance far away can be provided, so just can adapt to the operating mode of various complexity in the practical application.
