[0023] A parking equipment weight limiter includes a weighing platform 1, a weight sensor 2, a transmitter 3 and a host instrument 5. The weighing platform 1 is symmetrically fixed on the ground in front of a garage entrance 6, as close to the garage entrance 6 as possible without affecting the closing of the garage door. The weight sensor 2 and the transmitter 3 are fixedly installed inside the weighing platform 1. The host instrument 5 is fixedly installed on the wall next to the garage entrance 6 by bolts, with the lower edge about 1.6 meters above the ground, or installed and positioned according to customer needs. The weight sensor 2 is electrically connected to the host instrument 5 through the transmitter 3, and the host instrument 5 is electrically connected to the garage management system.

[0024] The weight sensor 2 adopts the FDZX-XB-0.2T sensor produced by our company, the transmitter 3 adopts the FDZX-BSQ-01 four-channel digital weighing transmitter produced by our company, and the host instrument 5 adopts the FDZX-TC3 instrument produced by our company. The host instrument 5 is provided with a first display window 501, a second display window 502, a setting key 503 and a voice alarm 504. The first display window 501 displays the weight of the first weighing, and the second display window 502 displays the weight of the second weighing. After 3 seconds, the first display window 501 displays "----", and the second display window 502 displays the sum of the first weighing weight and the second weighing weight. The setting key 503 is used to set the weight alarm value. The voice alarm 504 is used to issue a voice prompt when the vehicle weight exceeds the weight alarm value to remind the driver and garage staff that the vehicle is overweight.

[0025] The weighing platform 1 includes a base 101 and a slope 102. The slope 102 is symmetrically located at the front and rear ends of the base 101 with the top facing the base 101. The weight sensor 2 is fixedly installed on the side of the top of the slope 102. The base 101 is located above the weight sensor 2 and is fixedly connected to the weight sensor 2 by bolts. A certain gap is left between the base 101 and the slope 102 to avoid interference between the base 101 and the slope 102 when the vehicle is weighed. The slope 102 is fixed to the ground by expansion bolts.

[0026] A first crossbeam 103 is welded to the bottom of the top of the slope 102, and first mounting holes 104 are provided at the bottom of both ends of the first crossbeam 103. First grooves 105 are provided on the sides of both ends of the first crossbeam 103. Second crossbeams 108 are symmetrically welded to the bottom of the front and rear ends of the base 101, and second grooves 109 are provided at both ends of the second crossbeam 108. Mounting plates 106 are welded at the four corners of the base 101, and the mounting plates 106 are located in the second grooves 109. The mounting plates 106 are provided with second mounting holes 107. The weight sensor 2 is abutted against the mounting plate 106 and one end passes through the second groove 109 and the first groove 105. The weight sensor 2 is fixedly connected to the slope 102 and the base 101 through the first mounting hole 104 and the second mounting hole 107 respectively.

[0027] The transmitter 3 is fixed to the bottom of the base 101 by bolts.

[0028] Four weight sensors 2 and one transmitter 3 are provided in each weighing platform 1 . The weight sensors 2 are electrically connected to the input ends of the transmitter 3 , and the output ends of the transmitter 3 are electrically connected to the host instrument 5 .

[0029] The cable between the transmitter 3 and the host instrument 5 is covered with a corrugated tube, and the ground portion is covered with a wire trough speed bump 4 to protect the cable. The wire trough speed bump 4 is fixed to the ground by expansion bolts.

[0030] Working principle of this utility model:

[0031] The present invention is provided with eight weight sensors 2 with a rated load-bearing capacity of 8×0.2=1.6T. Since the front and rear wheels of the vehicle pass through the weighing platform 1 in sequence, the present invention is suitable for vehicles weighing 0-3.2T. After the utility model is installed, the weight alarm value is set by setting key 503 according to actual conditions. In this embodiment, the weight alarm value is set to 3T. When the vehicle wants to enter the automatic parking garage for storage, the front wheels of the vehicle first slowly pass through the weighing platform 1, and the weight sensor 2 transmits the front wheel weight information to the host instrument 5 and displays it in the first display window 501. When the rear wheels of the vehicle slowly pass through the weighing platform 1, the weight sensor 2 transmits the rear wheel weight information to the host instrument 5 and displays it in the second display window 502. The vehicle continues to move forward into the garage entrance 6. After 3 seconds, the first display window 501 displays "----" and the second display window 502 displays the gross vehicle weight. If the gross vehicle weight is less than or equal to 3T, it is not overweight, and the garage management system stores the vehicle according to the established procedure. If the gross vehicle weight is greater than 3T, the host instrument 5 sends a signal to the garage management system, and the garage management system stops working and does not store the vehicle. At the same time, the voice alarm 504 issues a voice prompt to remind the driver and garage staff that the vehicle is overweight and cannot be stored in this garage.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
