Problems solved by technology

[0002] As an indispensable part for the normal operation of the city, the manhole cover also has considerable economic value. Due to the special nature of the work of the manhole cover, the material for making the manhole cover must be a heat-resistant and cold-resistant metal material with relatively high hardness. Such a manhole cover It has a certain economic value, and the setting of the manhole cover facilities is removable, which will give criminals an opportunity to steal a large number of manhole covers, which will not only cause economic losses to the country and the people, but also to people. Generally, terminals with anti-theft alarm function use mechanical switches to judge the opening state of the manhole cover. There are problems such as non-waterproof, easy short circuit due to water ingress, short battery life, wired connection, and low switch sensitivity in winter. Disadvantages, the requirements for the environment are very high, and the service life of the anti-theft alarm device is reduced under harsh conditions. The existing anti-theft terminal uses GPRS communication, which has high communication and maintenance costs, and a lot of manpower and material resources are required to manage the SIM card of the GPRS module. The disadvantages greatly increase the cost of use, which is not conducive to the promotion of manhole cover anti-theft alarm devices

Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 The manhole cover wireless anti-theft alarm terminal shown has an outer box, which is round in shape. The outer box is composed of two parts, the upper cover 1 and the lower cover 2. The upper cover 1 and the lower cover 2 are connected by screws to provide a good seal. Effect, the side of the outer surface of the upper cover 1 is provided with an arc-shaped protrusion 3, the protrusion 3 can play an anti-slip effect, and the bottom surface of the outer surface of the upper cover 1 is provided with a direction identification mark 4, and the wireless anti-theft alarm terminal of the manhole cover is installed. It plays the role of direction identification. The position of the fold line in the middle of the b...

Abstract

The invention discloses a wireless anti-theft alarm terminal for a well lid. The wireless anti-theft alarm terminal comprises an outer box, wherein the outer box is composed of an upper lid and a lower lid, the upper lid is helically connected with the lower lid so as to well play a water proof and moisture proof function, a fixed connecting structure is arranged in the upper lid of the outer box, the fixed connecting structure is respectively connected and fixed with a power supply switch and a circuit board through screws, a power supply groove is formed in the upper lid of the outer box, a power supply is installed in the power supply groove, the power supply is connected with the power supply switch through an electric wire, the power supply switch is connected with the circuit board through the electric wire, the power supply switch is a gravity conductive ball sliding rail switch, and a wireless anti-theft alarm terminal (which is arranged adjacent to the circuit board) of the well lid can automatically organize a network, the circuit board is connected with an antenna through the electric wire, a connecting device of an external power supply is arranged in the upper lid, and a metal device connected with the antenna is arranged in the upper lid, so that the power consumption of the gravity conductive ball sliding rail switch is low, the use is safe, the open state of the well lid can be automatically monitored, and the position of the antenna can be automatically selected according to external environments, so that a signal is good and the antenna can be normally used under severe natural environments.
