Embodiment 1

[0022] An overload alarm system, including a manhole cover, a server, such as figure 1 As shown, the well cover includes a cylindrical cover body 5, the cover body is provided with a lifting hole 50, and the lifting hole can be used to lift the well cover after putting in the lifting handle. A normally open button 51 is arranged on the edge of the bottom surface of the cover body. The normally open button is in an open circuit or disconnected state when not being squeezed, and is in a closed or closed circuit state when being squeezed. A battery, a controller and a WIFI module are set in the cover, and a pressure sensor is set on the surface of the cover. The controller is connected with the battery, the normally open button, the WIFI module, and the pressure sensor. The controller is used to send and receive WIFI signals and Send the pressure sensor signal, the normally open button signal and the manhole cover number to the server. When the present invention is in use, the W...

Embodiment 2

[0029] A light-weight high-strength manhole cover. In this embodiment, the structure of the light-weight high-strength manhole cover is similar to that of the light-weight high-strength manhole cover in Example 1. They are all connected in series by wire ceramsite. The difference is that the concrete is prepared The ratio of the parts by weight of the raw materials is different. In this embodiment, the raw materials for preparation include the following parts by weight:

[0030] Cement: 50 parts, sand: 25 parts, fly ash: 25 parts, ceramsite 50 parts;

[0031] Wherein, the diameter of the ceramsite is 3-5 cm.

[0032] The pouring process of the lightweight high-strength manhole cover is:

[0033] Prepare the following preparation raw materials in parts by weight: cement: 50 parts, sand: 25 parts, fly ash: 25 parts, ceramsite 50 parts, foaming agent 1 part;

[0034] Wherein, the diameter of the ceramsite is 3-5 cm, and the ceramsite has three through holes through which metal ...

Embodiment 3

[0042] A light-weight high-strength manhole cover, the light-weight high-strength manhole cover is cast from ceramsite concrete, and the preparation raw materials of the ceramsite concrete include the following materials in parts by weight:

[0043] Cement: 40 parts, sand: 30 parts, fly ash: 20 parts, ceramsite 40 parts;

[0044] Wherein, the diameter of the ceramsite is 1-3 cm, the concrete structure also includes a metal wire, the ceramsite has a through hole for the metal wire to pass through, and the metal wire passes through the through hole and connects two or more of ceramsite.

[0045] The preparation process of the lightweight high-strength manhole cover is:

[0046] Prepare raw materials for preparation, which include the following materials in parts by weight: cement: 40 parts, sand: 30 parts, fly ash: 20 parts, ceramsite 40 parts, foaming agent 0.5 part;

[0047] Mix the cement, sand, fly ash, foaming agent and 25 parts by weight of water in the raw materials to ...

Abstract

The invention provides an overload alarm system based on the Internet of Things. The system comprises a server and a manhole cover, the manhole cover comprises a cylindrical cover body, a pull hole is arranged in the cover body, the edge of the bottom of the cover body is provided with a normally-open button, the cover body is internally provided with a battery, a controller and a WIFI module, the surface of the cover body is provided with a pressure sensor, the controller is connected with the battery, the normally-open button, the WIFI module and the pressure sensor, and the controller is used for sending received WIFI signals via the WIFI module and sending signals of the pressure sensor and the normally-open button and the number of the manhole cover to the server. The system can raise the alarm when a vehicle is overload as well as the manhole cover is opened, the manhole cover can receive and send the WIFI signals, manhole covers can be networked, construction of an emission station is not needed, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to an overload alarm system based on the Internet of Things. Background technique [0002] Existing roads have their design standards, such as allowing multiple vehicles with a single wheel to pass through, avoiding damage to the road due to overweight wheels, and the detection of these vehicles can only be detected by setting up checkpoints, which is very troublesome. At the same time, the existing manhole covers have at least the following problems: 1. The strength is not enough, and the manhole cover is often damaged. 2. There is no anti-theft alarm measure, and the manhole cover is often stolen. In the case of falling, 4. The equipment of the Internet of Things needs to set up multiple networked transmitting stations, which is costly. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an overload alarm s...
